Answer:
Step-by-step explanation:
2A:3B
= 5:6
3B:2C
= 36:15
A:C
= ?:?
2A/3B x 3B/2C
=5/6 x 36/15
=1/1 x 6/3
=1/1 x 2/1
=2
3B and 3B got canceled
For 2A and 2C, the 2 in front of A and C, got canceled as we are cross multiplying.
So I think the answer is
A:C
=1:1 ??
My answer could be wrong.

A model rocket is launched vertically from a platform 64 feet above the ground. The height of the rocket reaches during the flight is modeled by the equation h(t) = -16t² + 128x, where h is the height of the rocket and t is the time in seconds since the launch. Determine algebraically the time when the ball hits the ground.

[tex]2x-7y=9\\x+2y=10[/tex]
Answer:
x=8 y=1
Step-by-step explanation:
you have first and second equation, YOU MUST FIND THE THIRD EQUATION
SOLUTION
FIND equation 3 from 2
x+2y=10
x=10-2y...........3
Substitute equation 3 from first (not from the equation where you got equation 3)
2 (10-2y)-7y=9
20-4y-7y=9
-11y=9-20
-11y= -11
-11y/-11= -11/-11
y=1
Find the value of x from the third equation
x=10-2 (1)

Ayden had a goal of finishing painting at least 80\%80%80, percent of the 500500500 square meters of a house's walls by today. He actually finished painting 415415415 square meters today. Did Ayden meet his goal? Why? , Ayden painted square meters than his goal.
Answer: Yes, [tex]15\ m^2[/tex]
Step-by-step explanation:
Given
The surface area of the house [tex]A=500\ m^2[/tex]
Ayden aims to finish 80% of the painting
The actual painting done by him is [tex]A_c=415\ m^2[/tex]
Now 80% of the total is
[tex]\Rightarrow A'=500\times \dfrac{80}{100}=400\ m^2[/tex]
Clearly, actual painting done is more than 80% of the painting
[tex]\therefore[/tex] Ayden meet his goal
[tex]\Rightarrow A_c-A'=415-400=15\ m^2[/tex]
He painted [tex]15\ m^2[/tex] more than his target

Which inequality does the graph represent?
1. x>17
2.x<17
3.x<_17
4.x>_17
Answer:
1. x > 17
Step-by-step explanation:
When the point on the graph is an open circle you are going to be using < or > as an open circle means greater than or less than
Immediately we can eliminate number 3 and 4
When the line is going in the direction of the right than the inequality sign will face the variable (x)
the numbers are getting larger meaning that x is greater than the constant (17)
Hence, your answer is x > 17
Extra notes:
when the point on the graph is a closed circle ( filled in ) then you will use ≤ or ≥ as a closed circle means greater than or equal to or less than or equal to
Answer:
1. x > 17

Find the perimeter RST. Round answer to the nearest tenth. Show all the work !!!
Given:
The figure of a triangle RST on a coordinate plane.
To find:
The perimeter of the triangle RST.
Solution:
From the given graph it is clear that the vertices of the given triangle are R(-2,7), S(-5,1) and T(-7,-5).
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, we get
[tex]RS=\sqrt{\left(-5-\left(-2\right)\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-5+2\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-3\right)^2+\left(-6\right)^2}[/tex]
on further simplification, we get
[tex]RS=\sqrt{9+36}[/tex]
[tex]RS=\sqrt{45}[/tex]
[tex]RS=3\sqrt{5}[/tex]
Similarly,
[tex]ST=\sqrt{\left(-7-\left(-5\right)\right)^2+\left(-5-1\right)^2}[/tex]
[tex]ST=2\sqrt{10}[/tex]
[tex]RT=\sqrt{\left(-7-\left(-2\right)\right)^2+\left(-5-7\right)^2}[/tex]
[tex]RT=13[/tex]
Now, the perimeter of the triangle RST is
[tex]Perimeter=RS+ST+RT[/tex]
[tex]Perimeter=3\sqrt{5}+2\sqrt{10}+13[/tex]
[tex]Perimeter=26.032759[/tex]
[tex]Perimeter\approx 26.0[/tex]
Therefore, the perimeter of the triangle RST is 26.0 units.

Factor the following quadratic expression n^2+ 4n-12
Answer:
(n + 6)(n - 2)
Step-by-step explanation:
Given
n² + 4n - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the n- term (+ 4)
The factors are + 6 and - 2 , since
6 × - 2 = - 12 and 6 - 2 = + 4
Then
n² + 4n - 12 = (n + 6)(n - 2) ← in factored form

Answer: D, -13<-10
Step-by-step explanation:
Which ever way the open part of the '<' is facing, means that it is greater than the other number.
-13 is smaller than -10 so the open part of the symbol would face towards -10 and the pointy part would fact towards the -13.
