Answer:
1.5 as decimal, 1 1/2 as a fraction
Step-by-step explanation:
1. convert 2 5/6 & (-1 4/12) to a improper fraction.
17/6 and -16/12
2. multiply 17/6 by 2 to match -16/12's denominator
17/6 * 2 = 34/12
We now have
34/12 + -16/12
A positive number plus a negative number is the same thing as subtraction so we remove the negative sign and replace the plus with a minus sign.
We have:
[tex]\frac{34}{12}-\frac{16}{12}[/tex]
Now solve. 34-16 = 18
our answer is 18/12
what is the equation to the graph
Answer: y=2/(x-1)
Step-by-step explanation:
We can tell this is a rational function that looks somewhat like y=1/x, execpt that the asymptote is at x=1, not x=0. This means we have y=k/(x-1), where k is a constant.
Substituting in the coordinates of a point on the graph, say (0, -2), we get that -2=k/-1, meaning k=2.
So y=2/(x-1).
An angle measures 84° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
3 degrees and 87 degrees
Step-by-step explanation:
If the angle is x, its complement is (90-x).
This means that x+84=90-x.
2x=6
x=3.
So the measures are 3 degrees and 90-3=87 degrees

The domain of the square root parent function is x ≥ 0 as the square root of only non-negative values exists and that of negative values does not exist, while the domain of the cube root parent function is the set of all real numbers as the cube root of all numbers exists.
What is a function?A function is a relation between a dependent variable f(x) and an independent variable x, where for every value of x in its domain, there is one and only one value of f(x).
What is the domain of a function?The domain of a function is the set of values of x, for which f(x) exists.
What is the range of a function?The range of a function is the set of values of f(x), in a given domain of x.
How do we solve the given question?We are asked why is the domain of the square root parent function x ≥ 0 and the domain of the cube root parent function all real numbers.
We know that the domain of a function is the set of values of x, for which f(x) exists.
Let the square root parent function be f(x) = √x.
The domain of this function is x ≥ 0, as the square root of negative values does not exist in the real number system.
Let the cube root parent function be g(x) = ∛x.
The domain of this function is all real numbers, as the cube root of all values does exist in the real number system.
∴ The domain of the square root parent function is x ≥ 0 as the square root of only non-negative values exists and that of negative values does not exist, while the domain of the cube root parent function is the set of all real numbers as the cube root of all numbers exists.

Find the average yearly salary of an architect and a lawyer. The average yearly salary of an architect is $____ thousand
Answer:
Let x = salary of the architect, in thousands
Let 2x - 25 = salary of a lawyer, in thousands
2x + 2x - 25 = 206 (combined salaries, in thousands)
4x - 24 = 206
4x = 206 - 25 = 181
x = 45.25, in thousands.
The architect earns $45,250 yearly
The lawyer earns $65,500 yearly
If you want to set up a system of equations with 2 variables.
Let x = the salary of the architect, in thousands.
Let y = the salary of the lawyer, in thousands.
x + y = 206
y = 2x - 25
Solving by substitution will yield the same equation as above: x = 45.25 or $45,250
Then y = 2(45,250) - 25,000 = $66,500

A parallelogram has adjacent sides 25 cm and 6 cm . if one diagonal is 29 cm then find area , height corresponding to the sides 25 cm and perimeter.
very important question.....
plz do fast.
Answer:
height = 4.8 cm
area = 120 cm²
perimeter = 62 cm
Step-by-step explanation:
**Please refer to the attached diagram when following the step-by-step**
First, find m∠C (green angle on diagram) by using the cosine rule:
[tex]c^2=a^2+b^2-2abcos(C)[/tex]
[tex]\implies 29^2=6^2+25^2-2(6)(25)cos(C)[/tex]
[tex]\implies cos(C)= \frac{29^2-6^2-25^2}{-2(6)(25)}[/tex]
[tex]\implies cos(C)= \frac{180}{-300}=-\frac{3}{5}[/tex]
[tex]\implies cos(C)=126.8698976... \textdegree[/tex]
Therefore, the interior angle of the right triangle at point C (blue angle on diagram) is:
[tex]180-cos^{-1}(-\frac{3}{5})=53.13010235... \textdegree[/tex]
Now use the Sine Rule (for finding sides) to determine height (h):
[tex]\frac{6}{sin(90)}=\frac{h}{sin(53.13..)}[/tex]
[tex]\implies \frac{6}{1}=\frac{h}{\frac{4}{5}}[/tex]
[tex]\implies 6 \times \frac{4}{5}=h[/tex]
[tex]\implies h=\frac{24}{5}=4.8[/tex]
So the height = 4.8 cm
Now we have determined the height, we can calculate the area by using the area of a parallelogram formula:
Area of a parallelogram = base x perpendicular height
⇒ area = 25 x 4.8 = 120 cm²
Parallelogram is a four-sided shape made up of two pairs of straight parallel lines that are equal in length.
Perimeter = sum of the sides
⇒ perimeter = 6 + 6 + 25 + 25 = 62 cm

Julian owns a small business selling bagels. He knows that in the last week 57 customers paid cash, 12 customers used a debit card, and 70 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a debit card as a fraction in simplest form.
Considering the definition of probability, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].
Definition of probabilityProbability is the greater or lesser chance that a given event will occur.
In other words, the probability establishes a relationship between the number of favorable events and the total number of possible events.
Then, the probability of any event A is defined as the ratio between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases.
[tex]P(A)=\frac{number of favorable events}{ total number of possible events}[/tex]
The probability of event A can only be a number between 0 and 1; although it can also be written as a percentage.
Probability that the next customer pay with a debit cardIn this case, you know:
Total number of customers = 57 +12 +70= 139 (total number of possible cases)The number of customers that used a debit card = 12 (number of favorable cases)Replacing in the definition of probability:
[tex]P(A)=\frac{12}{ 139}[/tex]
Finally, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].

The integer m whose factors are 15,12,10 and 6 is 60 and 8 is not, therefore, for integer 60, 8 will be not the factor so option (D) is correct.
What is an integer?An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.
Integer ; ....-2 , -1 , 0 , 1 , 2 , .....
Integers are non-decimal numbers and all integers are rational numbers.
The factors of 10 ⇒ 2 × 5
The factors of 12 ⇒ 2 × 2 × 3
The factors of 10 × 12 ⇒ 2 × 5 × 2 × 2 × 3
We can make all factors by 2 × 5 × 2 × 2 × 3 like 5 × 3 = 15 , 2 × 2 × 2 = 8.
So find a number whose all will be a factor except one.
The factor of 60 ⇒ 2 × 2 × 3 × 5
We cannot make 8 by this factor but can make 15,12,10,6.
Example 15 = 3 × 5 , 12 = 2 × 2 × 3
Hence "The integer m whose factors are 15,12,10 and 6 is 60 and 8 is not, therefore, for integer 60, 8 will be not the factor".

A 3m ladder stands on horizontal ground and reaches 2.8 m up a vertical wall. How far is the foot of the ladder from the base of the wall?
Step-by-step explanation:
let T be the top of the ladder
let F be the foot of the ladder
let B be the base of the wall
you need to find the distance between the foot of the ladder and the base of the wall, in other words the distance of the 'ground' ( refer to the diagram).
you are given that the hypotenuse - H is 3 m and that the opposite - O ( wall ) is 2.8 m.
i) find the angle
given
H, O → use SOH, sin.
sin x = opp. /hyp.
sin x = 2.8 / 3
x = sin-1 ( 2.8/ 3)
x = 68.960...
x = 70.0 ° ( 3 s.f)
ii) use either tan or cos to find the adjacent (wall)
using TOA, tan:
tan ( 68.96) = 2.8/ adj.
2.8 / adj. = tan (68.96)
adj. × tan (68.96) = 2.8
adj = 2.8/ tan (68.96)
adj = 1.0770...
adj. = 1.08 ( 3 sf)
base = 1.08 m
or you could rather simply work this out using Pythagoras Theorem:
where hyp. is c², the base is b² and height is a²;
c² = a² + b²
b² = c² - a²
b² = (3)² - (2.8)²
b² = 1.16
b = √1.16
b = 1.0770
b = 1. 08 m ( 3sf)
you can give your answer to 3 sf or 2 sf.
hope this helps you!

Answer:
<DEF = 107
Step-by-step explanation:
The way to best solve this problem is by starting with angle F. Remember that all angles in a straight line must add up to 180. So by subtracting 135 from 180 we get 45 for angle F.
180 - 135 = 45
After that, we can figure out the measure of <DEF. All the angles of a triangle must add up to 180. So:
180 - 28 - 45 = 107
Making the answer 107 for the measure of <DEF
Each 1/2 centimeter on a map represents an actual length of 1/8 of a meter.
What length on the map represents 1 meter?
1/16 centimeter
5/8 centimeters
2 centimeters
4 centimeters
Answer:
4 cm
Step-by-step explanation:
1/8·n = 1/2
multiply each side by 8/1
n = 8/2 or 4
The length on the map that represents 1 meter in real is 4 centimeters.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that Each 1/2 centimeter on a map represents an actual length of 1/8 of a meter. Therefore, the ratio can be written as,
Length on Map / Actual Length = (1/2) centimeters / (1/8) meters
Length on Map / Actual Length = 4 centimeters per meters
Now, the length on the map that represents 1 meter in real is,
Length on Map / Actual Length = 4 centimeters per meters
Length on Map / 1 meter = 4 centimeters / 1 meters
Length on Map = 4 centimeters
Hence, the length on the map that represents 1 meter in real is 4 centimeters.

through: (-2, 4), slope = -7/-2
the formula is: y=mx+b
Answer:
[tex]y=\frac{7}{2}x+11[/tex]
Step-by-step explanation:
To solve, we need to find the y-intercept (b). In order to find the y-intercept, we can plug in the slope and the (x,y) coordinate pair given to us into the equation to solve for the y-intercept:
y=mx+b
4=(-7/-2)*-2+b
4=14/-2+b
4=-7+b
Add 7 to both sides
b=11
Therefore the equation is:
[tex]y=\frac{7}{2}x+11[/tex] (note that the fraction is positive since the two negatives cancel out)
If you're good at math, please help: Find the constants a and b such that the function is continuous on the entire real line.
Answers:
a = -2
b = -1
==========================================
Explanation:
The first piece 5 must match up with the ax+b when x = -2, or else the function wouldn't be continuous at this junction.
Plug in x = -2 and set the result equal to 5
We end up with -2a+b = 5
Solving for b gets us b = 5+2a
--------------
The middle piece ax+b must also equal the third piece -5 when x = 3 to ensure the second junction is continuous.
This leads us to the equation 3a+b = -5
Apply substitution and solve for 'a'
3a+b = -5
3a+5+2a = -5
5a+5 = -5
5a = -5-5
5a = -10
a = -10/5
a = -2 is one of the answers
Then use this to find b
b = 5+2a
b = 5+2(-2)
b = 5-4
b = -1 is the other answer
