witch ratio is equivalent to 1:2 A. 9:18 B.24:12 C.7:14
Answer:
C
Step-by-step explanation:
What is the slope-intercept form of this equation? Show all your work. 6x + 2y = 12
from converting the linear equation 6x - 2y = 12 and slope intercept form we have to transpose terms to get the value of y hence equation and slope intercept form is y = 3x - 6.

Diego is 78 years old. Kendra is 32 years old. How many years until Diego's age is 2 times Kendra's age?
Answer:
39
Step-by-step explanation:
Because if you want to know how many years until you get there you would need to divide to find how many year until Diego turns 2 times her age because the opposite of multiplication is division since they said 2 times
1. In a concert hall, the number of seats in each row increases as you move farther from the stage. There are
the first row, 38 seats in the second row, and 45 seats in the third row.
a) If this pattern continues, determine what type of sequence this represents. Then write a function rule in simplified
form that can be used to find the number of seats in the nth row. Be sure to use the correct notation you have
learned this unit. Show ALL work.
b) Use the rule to determine which row has 290 seats. Show ALL work.
According to the situation described, we have that:
a) The arithmetic sequence that gives the number of seats in the nth row is given by:
[tex]a_n = 24 + 7n[/tex]
b) The 38th row has 290 seats.
What is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
Item a:
The first row has 31 seats, the second has 38, the third has 45 and so on, hence:
It is an arithmetic sequence.The common difference is d = 7.The first term is [tex]a_1 = 31[/tex].Then, the rule is:
[tex]a_n = a_1 + (n - 1)d[/tex]
[tex]a_n = 31 + 7(n - 1)[/tex]
[tex]a_n = 24 + 7n[/tex]
Item b:
This is the nth row, for which [tex]a_n = 290[/tex], hence:
[tex]a_n = 24 + 7n[/tex]
[tex]290 = 24 + 7n[/tex]
[tex]7n = 266[/tex]
[tex]n = \frac{266}{7}[/tex]
[tex]n = 38[/tex]
The 38th row has 290 seats.

A fire department's longest ladder is 110 feet long, and the safety regulation states
that they can use it for rescues up to 100 feet off the ground. What is the maximum
safe angle of elevation for the rescue ladder?
Also can you guys draw a picture of the right triangle and show work
See the attached picture for the answer:
Answer:
The maximum angle they can use the ladder is 65.38º
Step-by-step explanation:
Sine law allows sinA/a = sin B/b = sin C/c
Reference the drawing attached
sin 90/110m = sinB/100m
1/110m = sinB/100
multiply both sides by 100
100/110 = sinB
divide each side by 10
10/11 = sinB
find inverse sin of both sides
sin^-1(10/11) = B
65.38º = B

Given in the question, [tex]\frac{4}{5} =\frac{y}{7} \\[/tex], using the concept of direct proportion, y = 5.6
Direct proportion is the concept of proportionality where one variable increases/decreases when another increases/decreases and vice versa. The rate of increase/decrease can be measured through the constant ratio. The two quantities which are directly proportional are related by a Direct Proportion symbol '∝'.
Given in the question,
[tex]\frac{4}{5} =\frac{y}{7} \\[/tex]
multiplying 7 on both sides,
[tex]\frac{4}{5}*7 = \frac{y}{7} *7\\ \\ \frac{28}{5} = y \\\\y = 5.6[/tex]

First we need the height of the cone
so we divide the cone to two equal parts that means the adjacent 5 inches will be divided into two to give 2.5
then we use get a triangle from the cone and that's how we find our height using pythagoras theorem
hypotenuse Square = opposite Square + adjacent Square
7^2 = x^2 + 2.5^2
therefore our height is 6.53
now to get the surface area of the cone we use the formula
pi×r( r + Square root of r^2 + h^2

100 points, put nonsense, get reported. Susan wants to build a floor to put at the bottom of her tree house. She made the scale drawing below using a scale of 2.5 in = 3 ft. Enter the length Susan must use for the floor.
Divide the length of the scale drawing by the scale (2.5) then multiply that by the scale feet (3)
11 inches / 2.5 = 4.4
4.4 x 3 = 13.2 feet
Answer: 13.2 feet

Kiara sets up a passcode on her smart phone, which allows only eight-digit codes. A spy sneaks a look at Kiara's smart phone and sees her fingerprints on the screen over
eight numbers. What is the probability the spy is able to unlock the smart phone on his first try? Express your answer as a fraction in lowest terms or a decimal rounded
to the nearest millionth.
Probabilities are used to determine the chances of events
The probability the spy is able to unlock the smart phone on his first try is 0.00000001
How to determine the probabilityThe length of the password is given as:
L = 8
Each of the digit in the password can take any of digits 0 - 9 (i.e. 10 digits)
So, the number of possible password is:
[tex]n = 10^8[/tex]
The probability that the spy unlocks the phone is:
[tex]p =\frac 1n[/tex]
So, we have:
[tex]p = \frac 1{10^8}[/tex]
Simplify
[tex]p = 0.00000001[/tex]
Hence, the probability the spy is able to unlock the smart phone on his first try is 0.00000001

Step-by-step explanation:
-5x - 8 > 22
Add 8 to both sides: -5x > 30
Divide both sides by 5: -x > 6
Divide both sides by -1 (reverse sign): x < -6
Answer:
x < -6
Step-by-step explanation:

look at the file customer A is your answerTo visit the manila Zoo, 11 adults and 5 Children have to pay 270 whereas 14 adults and 9 children have to pay 370? Find the total amount a family of 2 adults and 3 children has to pay to visit the zoo.
Step-by-step explanation:
let adults be x and childrens be y
a/q
11x + 5y = 270
14x + 9y = 370
→ x = -5/11y + 270/11 ; 14x + 9y = 370
→ 14(-5/11y + 270/11) + 9y = 370
→ y = 10
→ x = -5/11 × 10 + 270/11
→ x = -50/11 + 270/11
→ x = 20
therefore, we got
x = 20, y = 10
each adult have to pay 20 and each children have to pay 10
so,
2 × 20 = 40
3 × 10 = 30
40 + 30 = 70
for a family of 2 adults and 3 children they have to pay 70.

solve for x,y, and 15
Answer:
27
Step-by-step explanation:
x + y = 15 (gallons) (1)
0.25*x + 0.10 * y = 0.15 * 15 (2)
Multiply 100 on (2):
25x + 10y = 15
Divede by 5
5x + 2y = 3 (3)
From (1) y = 15 - x
so 5x + 10*(15 - x) = 15
5x + 150 - 10x = 15
-5x = 15 - 150 = -135
x = 135/5 = 27 (gallons)
