Step-by-step explanation:

3,230 x 80% = 3,230 x 0.8

3,230 x 80% =2584

2584+3230=5,814

Answer:

A opens upward

Step-by-step explanation:

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

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

So we can see 49cm is the longest.

x = 120 : 3

x = 40°

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

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

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

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.

The shower head follows a linear function

From the complete question, we understand that:

Each minute, 5 gallons of water are used

This mean that, the possible ordered pairs are:

[tex]\mathbf{(x,y)= \{(1,5),(2,10),(3,15).....\}}[/tex]

When the shower head is used for 0 minutes we have:

[tex]\mathbf{(x,y)= \{(1-1,5-5)\}}[/tex]

[tex]\mathbf{(x,y)= \{(0,0)\}}[/tex]

The ordered pair when the shower head is used for 0 minutes is (0,0)

The location on the graph is called the y-intercept.

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

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!
