Please help me with this problem it is pair each of triangles are similar but not drawn to scale. Calculate any lettered lengths
b = 5.5m a = 6m
b = 17cm a = 80cm
Step-by-step explanation:
The second triangle in the pair is a scaled-up version of the first triangle.
To find b in the first triangle you do 11/2 = 5.5m
To find a in the second triangle you do 3*2 = 6m
To find b in the third triangle you do 68/4 = 17cm
To find a in the fourth triangle you do 20*4 = 80cm

3 A piece of ibbon of lengh 84 cm is divided
into three pieces in the ratio 1:47. Calculate the
length of the longest pieces
?
Add the 3 ratio portions together: 1 + 4 + 7 = 12
Divide total length by 12:
84/12 = 7
Multiply each ratio portion by 7:
1 x 7 = 7
4 x 7 = 28
7 x 7 = 49
The longest piece is 49 cm
Answer:
49cm
Step-by-step explanation:
1x+4x+7x=84
12x=84
X=7
4*7=28
7*7=49

Given that f(x) = x^2– 5x– 36 and g(x) = x + 4, find (f +9)(x) and express

Cheyenne's car is in the shop, so she needs to rent a car for 4 days. The cost of a
rental car is $24.99 per day, and she will be charged $0.18 per mile for every mile
she drives over 200 miles. If she drives 300 miles and the sales tax she pays on the
rental is 5.5%, how much will she pay for this rental?
$117.96
$130.94
$99.96
$124.45
Answer:
Cheyenne's rental car will cost $124.45
Step-by-step explanation:
24.99(cost/day)*4 days=99.96
300(mi driven)-200(mi allowed)=100 miles that must be paid for
100*.18(cost per mile)=18.00
99.96+18.00=117.96
117.96*.055(5.5% tax rate)=6.49
117.96+6.48=124.45

Bounces in the horizontal plane
Balon7.gif (2174 bytes)
When a ball bounces off a rigid board, the component of the velocity perpendicular to the board decreases in value, leaving the parallel component unchanged
v x = u x
v y = -e u y
Heights of successive bounces
Suppose a ball is dropped from an initial height h . We are going to calculate the heights of the successive bounces.
1.-First bounce
The velocity of the ball before it hits the ground is calculated by applying the principle of conservation of energy
The velocity of the ball after the collision is (in modulus) v 1 = e u 1
The ball ascends with an initial velocity v 1 , and reaches a maximum height h 1 which is calculated by applying the principle of conservation of energy
2.-Second bounce
The velocity of the ball before it hits the ground is calculated by applying the principle of conservation of energy
The velocity of the ball after the collision is v 2 = e u 2
The ball ascends with an initial velocity v 2 , and reaches a maximum height h 2 which is calculated by applying the principle of conservation of energy
3.-Bounce n
After collision n , the maximum height the ball reaches is
h n = e 2n h
Loss of energy experienced by the ball
In the first collision, the ball loses an energy
In the second collision, the ball loses an energy
In the collision n the ball loses an energy
The sum of Δ E 1 + Δ E 2 + Δ E 3 +…. Δ E n is the energy lost by the ball after n collisions. After infinite collisions the ball will have lost all its initial energy mgh . We are going to check it by adding the infinite terms of a geometric progression of ratio e 2 and whose first term is Δ E 1
Time it takes for the ball to stop.
The time it takes for the ball to reach the ground when dropped from a height h from rest is
The ball bounces and rises to a height h 1 , then falls back to the ground. The time it takes to go up and down is
The ball bounces and rises to a height h 2 , and then falls back to the ground. The time it takes to go up and down is
The total time after infinite bounces is the sum of t 0 and the terms of a geometric progression whose first term is 2 t 0 e and whose ratio is e.
If the ball is given a horizontal initial velocity v x . After infinite bounces, it moves a horiz

3/400 as a percent step by step explanation
Answer:
0.75%
Step-by-step explanation:
First, do 3 divided by 4 which is 0.0075. But this is in decimal form, so we have to multiply this by 100. 0.0075 x 100 is 0.75, so therefore the fraction, 3/400 as an percentage is 0.75%. I hope this makes sense!
A store is open 9 hours each day. It is open 6 days each week. How many hours hours is the store open each week. Explain how you can find the answer using Distributive property with multiplication and subtraction
Answer:
54 hours
Step-by-step explanation:
9 hours everyday, so you just mulitply the amount of the hours to the amount of days. equation: 9x6
The hours is the store open each week would be 54 hours
What is the distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
a(b + c) = a x b + a x c
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space). This property is known by distributive law and applies to subtraction also.
Given that store is open 9 hours each day. It is open for 6 days each week.
Using Distributive property with multiplication and subtraction;
we just need to multiply the number of hours by the number of days. equation:
9 hour every day
9 x 6 = 54 hours
Hence, 54 hours every day the store is open each week.

Help me pleaseeee I need help
Answer:
a. 640 times 0.15 plus 8$ for monthly is 104dollars
b. kilowatts/hour, rise over run
c. 53-8 divided by 0.15 is 300 kilowatts
Please use the graph to answer
Answer:
Step-by-step explanation:
Pick two points and calculate the slope (Rise/Run).
I picked (-2,0) and (2,-2)
Rise = (-2 - 0) = -2
Run = (2-(-2)) = 4
Slope (Rise/Run) = -2/4 or -1/2
The line has an intercept of -1 (the "b" in y=mx + b)
So the equation is y = -(1/2)x -1
