Answer:

Step-by-step explanation:

B) Small triangle:

height = 20 - 15 = 5

base = 1

height to base =  5 :1

Medium triangle :

height = 60 -30 = 30

base = 2

height to base =  30 :2  = 15 :1

Large triangle:

height = 120 - 60 = 60

base = 4

height to base =  60 : 4 = 15 : 1

c) The ratios are same. This is true because wage and working hours are in direct proportion.

E) Take any two points. (1 , 15) & (2 , 30). Find the slope.

Slope = Change in y ÷ change in x

 m = (30-15) ÷ (2 -1) = 15/1 = 15

y -y1 = m(x -x1)

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x - 15 + 15

y = 15x

The answer is: Y= 15x

Volume of smaller cube:

CLAIM:

Examine the system model below, which shows a car moving along a track at two different points in time. Assume there is no friction between the car and the track.


In the before image, a car is moving along a track at a constant speed towards a motionless wheel.


In the after image, the car has contacted the wheel, which begins to spin. The car continues to travel along the track at a slower speed.


THE QUESTION:

Which Claim below best explains what causes the wheel to spin after contact with the car?

1 - The wheel stops spinning because kinetic energy was transferred from the car to the wheel.

2 - The wheel begins to spin because kinetic energy was transferred from the car to the wheel.

3 - The wheel pushes the car, causing it to go faster

4 - The wheel begins to spin because kinetic energy was transferred from the wheel to the car.

Latasha deposits 250$ into a account savings. The simple intrest rate paid is 3.5%. how much interest does Latasha earn in one year?

Answers

Multiply $250 by 3.5% = 8.75
250 + 8.75 = 258.75

The amount of interest that Latasha earns in one year will be $8.75.

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

The formula for interest is written as,

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

Latasha deposits $250 into her account savings. The simple interest rate paid is 3.5%.

Then the amount of interest that Latasha earns in one year will be given as,

I = ($250 x 3.5 x 1) / 100

I = $875 / 100

I = $8.75

The amount of interest that Latasha earns in one year will be $8.75.
