Answer:
x=7 y=6
Step-by-step explanation:
x = 7 hous worked by Lillian
y = 6 hours worked by Jacob
Step-by-step explanation:
Let call " x " and " y " numbers of hours Lillian and Jacob worked respectively, then according to problem statement we have:
They both combined a total of 13 hours, therefore
x + y = 13 ⇒ y = 13 - x
And the number of ironed shirts was 295 then we have
25*x + 20*y = 295
We need to solve that system of equations for x and y then
25*x + 20 * ( 13 - x ) = 295
25*x + 260 - 20*x = 295
5*x = 295 - 260
5*x = 35
x = 35/5
x = 7
And y = 13 - x ⇒ y = 13 - 7
y = 6
A factory is going to hire 33 new employees. There are 79 applicants. Which
choice represents the ratio of new hires to applicants?
Answer:
33:79
Step-by-step explanation:
We are told that a factory is going to hire 33 new employees.
and the total applicants is 79
In this problem, we want to represent the situation as a ratio of new hires to applicants
Since the question says new hires to applicants
Hence, the ratio will be
33 to 79
or
33/79, we can simplify this as
33:79
Triangle A is a right triangle. The hypotenuse is 10”. One side is 8”. Find the other side.
12.8. is answer by formula
^^ this is the last oneeee
Answer:
30 degrees
Step-by-step explanation:
So a complete circle consists of 360 degrees but we are trying to find what ADB equals so we are going to subtract BDC and ADC from 360:
BDC = 150
The graph does not say what ADC equals so we are going to look at the graph and see that ADC is half of the circle so we are going to divide 360 by 2:
360/2 = 180
So ADC equals 180, since we know what ADC and BDC equal we are going to add them together and then subtract them from 360:
180 + 150 = 330
360 - 330 = 30
So ADB = 30 degrees
Hope this helps!

The equation for line p can be written as y = 1/4x + 3. Line q includes the point (-1, 5) and is
perpendicular to line p. What is the equation of line q?
Answer:
[tex]y=-4x+1[/tex]
Step-by-step explanation:
To get this, use the following steps:
1) Knowing that line q is perpendicular to the line p, the slope of line q must be the negative reciprocal of the slope of line p. Thus the slope is [tex]-(\frac{1}{4})^{-1} = -4[/tex]
2) To find the equation, plug in the point given:
[tex]5 = -4(-1) + b[/tex]
[tex]b = 1[/tex]
3) The equation of line q is thus:
[tex]y= -4x+1[/tex]

A rectangular monitor’s size is measured diagonally from 1 corner to the opposite corner. What is the size of a rectangular monitor that is 30 centimeters wide by 24 centimeters high, to the nearest centimeter?
Answer:
38cm
Step-by-step explanation:
Using the Pythagorean Theorem, it is found that the size of the monitor is of 38 centimetres.
------------------------
In a right triangle with legs [tex]l_1[/tex] and [tex]l_2[/tex] and hypotenuse h, these measures are related by the Pythagorean Theorem, given by:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In this problem:
The diagonal of the rectangle, which is the size of the monitor, is the hypotenuse.The width of [tex]w = 30[/tex] and the length of [tex]l = 24[/tex] are the legs, thus:[tex]s^2 = l^2 + w^2[/tex]
[tex]s^2 = 24^2 + 30^2[/tex]
[tex]s = \sqrt{24^2 + 30^2}[/tex]
[tex]s = 38[/tex]
The size of the monitor is of 38 centimetres.

The table below represents a linear function f(x) and the equation represents a function g(x):
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)
Part B: Which function has a greater y-intercept? Justify your answer. (4 points)
(10 points)
Answer:
Step-by-step explanation:
Part A
for f(x) slope between points (-1,-6) and (1,0)
m= y2-y1/x2-x1 = -6-0/-1-1 = -6/-2= 3
for g(x) slope m=4 because we compare to equation y=mx+b the given equation g(x)=4x-5
The slope of f(x) is 3 and the slope g(x) is 4 so the line of g(x) is steeper
part B
The y intercept for g(x) is (0, -5)
The equation of f(x) can be found
y-y1 =m(x-x1) take any point for example point (1,0)
y-1 =3(x-0)
y=3x+1 so the y-intercept is at (0,1)
The y-intercept for f(x) is greater at y=1 then the one of g(x) at y=-5
Whats the slope of (6,0) and (2,-2)
can someone plz help i need to graph it and identify the x-intercept
Answer:
(-7/2,0) is the x intercept
Step-by-step explanation:
1. y+3 = -6/7x
2. -3 -3 ....subtract 3 from both sides to isolate the variable y
y= =-6/7x -3 ....is your new equation
You graph it by putting your point on negative three and then counting 6 units down and 7 units right.
For the x intercept you set y to 0 and solve for x
0= -6/7x -3
+3 +3 ...to both sides
3= -6/7x .....divide both sides by -6/7
-7/2=x

Annika sells 6 inch pies for $5.00 and 8 inch pies for $9.00 each. Last week she sold twice as many 6 inch pies as she did 8 inch pies. She made $133.00 from her sales. Annika defined x as the number of 6 inch pies she sold and y as the number of 8 inch pies she sold. She wrote the system below.
6 x + 8 y = 133. 2 x = y.
Which statements about the system are true? Check all that apply.
Since the cost for each pie is $5 and $9, the first equation should be 5 x + 9 y = 133.
Since the 8 inch pies are 2 inches larger, the second equation should be x + 2 = y.
Since there are fewer 8 inch pies, the second equation should be x = 2 y to balance the values.
The first equation is correct because 6x represents the money earned for 6 inch pies and 8y represents the money earned for 8 inch pies.
The second equation is correct because there are more 6 inch pies and 2 times a number is always more.
Answer:
See below!
Step-by-step explanation:
Only the first choice is accurate.
The second choice is incorrect since it doesn't accurately represent the situation described.
The third choice is incorrect since it also doesn't accurately represent the situation described.
The fourth choice is incorrect since the equation is meant to show the cost of the pies, not the size.
While the fifth choice is correct in that the second equation is accurate, the reasoning is inaccurate.
Answer
Only option 1 is correct

59°
P
7 m
g

T
U
The answer is below
Step-by-step explanation:
Two triangles are said to be congruent if for the two triangles all the three sides are equal and all the three angles are equal to each other.
Given that ΔPQR is congruent to ΔSTU, hence all corresponding sides and corresponding angles are equal to each other.
∠P = ∠S = 59°
∠S + ∠T + ∠U = 180° (sum of angles in a triangle)
59 + 75 + ∠U = 180°
134 + ∠U = 180°
∠U = 46°
∠U = ∠R = 46°
∠Q = ∠T = 75°
Also, for the sides:
ST = PQ = 7 m
SU = PR = 8 m

On a busy day, a shop sells a total of 15 desks and chairs for a total amount of $960.The desks sell for $120 each and the chairs sell for $50 each.
(a) Express the information as two equations. Let d equal the number of desks and let c equal the number of chairs.
(b) Solve the equations simultaneously to find how many of each were sold.
Answer:
- sold 15 desks + chairs
- each desk is $120
- each chair is $50
- total amount is $960
- desk = d
- chairs = c
(a) i/ d + c = 15
ii/ 120d + 50c = 960
(b) d+c = 15 --------- (1)
120d + 50c = 960 --------(2)
from (1) d+c = 15
c = 15-d --------- (3)
substitute (3) into (2)
120d + 50c = 960
120d + 50(15-d) = 960
120d + 750 - 50d = 960
120d - 50d = 960 - 750
70d = 210
d = 210/70
d = 3
substitute d=3 into (3)
c = 15-d
c = 15-3
c = 12
thus, 3 desks and 12 chairs were sold
