Answer: 38

Step-by-step explanation:

Answer:

Perimeter= 38, EC- Area= 19.5

Step-by-step explanation:

substitute all the x's for 5. simplify each equation. H=3, Base= 13, 4x+2=22

h- 5-2=3

4(5)+2=22

base- 2(5)=3=13

then add all answers together to get 38.

multiply 13 and 3 to get 39, then divide by 2 to get 19.5 for the area.

find the area.......

Jack had $200 when he got to the festival. He spends $4 per ride. The equation T = 200 – 4R models his amount of money. If he has $100 left how many rides did he go on

Answers

Answer:

Step-by-step explanation:

Given the equation :

T = 200 - 4R

T = amount of money left ; if T = $100

R = number of rides

$100 = 200 - 4R

$100 - $200 = - 4R

-$100 = - 4R

R = 100/ 4

R = 25

25 rides

mya bought some pizza for $12 each . f p represents the number of pizza she bough , what expression shows the total amount she spent ?

Answers

Answer:

Step-by-step explanation:

f(p)=12p

Answer:

12p

Step-by-step explanation:

Since each pizza costs $12 dollars and "p" represents how many pizzas she bought, you multiply 12 by "p" to get the total amount of money that she had spent.

Let the number be (10 x + y)

Then, 10 x + y = 3 * (x + y) (given)

Or, 10 x + y = 3 x + 3 y

Or, 10 x - 3 x = 3 y - y

Or, 7x = 2 y

Or, x = 2 y / 7 ( Eq. 1)

Also, 10 x + y + 45 = 10 y + x ( given)

Or, 10 x - x = 10 y - y - 45

Or, 9 x = 9 y - 45 ( Eq. 2)

Substituting the value of x from (Eq. 1) in (Eq. 2), we have:

9 * 2 y / 7 = 9 y - 45

Or, (9 y ) - (18 y / 7) = 45

Or, 63 y - 18 y = 315

Or, 45 y = 315

Or, y = 7

From (Eq. 1),

x = 2 * 7 / 7 = 2

So, the number is 10 x + y = (10 * 2) + 7 = (20 + 7) = 27

Answer

Check:

Sum of the digits = 2 + 7 = 9

9 * 3 = 27 ✓

Adding 45 to the number 27, we get 72. So, the digits get reversed.

If a bowling ball is dropped out of an airplane,
what will its speed (velocity) be after 3.4
seconds, assuming no air resistance? (Hint: Use
the equation v = 32t).

Answers

Answer: The velocity of the ball is 108.8 ft/s downwards.

Step-by-step explanation:

When the ball is dropped, the only force acting on the ball will be the gravitational force. Then the acceleration of the ball will be the gravitational acceleration, that is something like:

g = 32 ft/s^2

To get the velocity equation we need to integrate over time, to get:

v(t) = (32ft/s^2)*t + v0

where v0 is the initial velocity of the ball. (t = 0s is when the ball is dropped)

Because it is dropped, the initial velocity is equal to zero, then we get:

v(t) = (32ft/s^2)*t

Which is the same equation that we can see in the hint.

Now we want to find the velocity 3.4 seconds after the ball is dropped, then we just replace t by 3.4s, then we get:

v(3.4s) = (32ft/s^2)*3.4s = 108.8 ft/s

The velocity of the ball is 108.8 ft/s downwards.

school is only 5 days a week and if she walks 60 yards to the bus stop and 60 yards back from the bus stop than she walks a total of 120 yards a day

120 x 5 =600 the answers are in feet so we need to convert to feet and to do that we need to multiply by 3

600x3=1800

so she walks 1800 feet in a normal school week

2(1 – x) > 2x HELP ASAP!!! I CANT FIGURE THIS OUT

Answers

Answer: x < 1/2

This is the same as saying x < 0.5 since 1/2 = 0.5

====================================================

Work Shown:

2(1-x) > 2x

2*1 + 2*(-x) > 2x ..... distribute

2 - 2x > 2x

2 > 2x+2x .... adding 2x to both sides

2 > 4x

4x < 2 ..... flip both sides; flip the inequality sign

x < 2/4 ..... dividing both sides by 4; see note below

x < 1/2

Note: We do not flip the inequality sign here because we are dividing both sides by a positive value. The inequality sign would only flip if you divide both sides by a negative number.
