If x represents hours worked and y represents total earnings in dollars, then the equation that corresponds to the earnings of someone who makes $12.75 an hour is___.A. x = 12.75y
B. y = 12.75x
C. y = 12.75 + x
D. y = 12.75/x

Answers

Answer 1

Answer:

The correct option is B. y=12.75x

cuz, y = total earnings

and x = hours worked

so total earnings(y) should be equal to the amount of money paid for an hour(12.75) * number of hours worked

Annual Percentage Yield (APY) of Burt's savings account is 2.5%

Step-by-step explanation:

Annual percentage rate refers to the annual percentage return of the saving account held by Burt's. The interest rate is compounded annually. Hence, the interest is added annually to the account.

Annual Percentage yield refers to the real rate of return that is earned on the savings. This interest is accrued in compounding fashion. Higher the interest rate more is the amount returned.

Hence, the Annual Yield of the Burt's savings account is 2.5%

Determine the equation of the line that passed through the given points. (-5,10) and (5,-10)

Answers

Answer:

$y=-2x$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=(y2-y1)/(x2-x1)$

we have

(-5,10) and (5,-10)

substitute the values in the formula

$m=(-10-10)/(5+5)$

$m=(-20)/(10)$

$m=-2$

step 2

Find the equation in point slope form

$y-y1=m(x-x1)$

we have

$m=-2$

$point\ (5,-10)$

substitute

$y+10=-2(x-5)$

step 3

Convert to slope intercept form

$y=mx+b$

isolate the variable y

apply distributive property right side

$y+10=-2x+10$

$y=-2x$

a train travels 210 miles in 3 hours moving at a constant speed. Find the speed of the train in miles per hour .

Answers

If a train travels 210 miles in 3 hours moving at a constant speed then the speed of the train is 70 miles per hour

What is Speed?

Speed is the time rate at which an object is moving along a path,

Given that a train travels 210 miles in 3 hours moving at a constant speed.

We have to find the speed of the train in miles per hour .

Speed= Distance/time

Distance = 210 miles

Time = 3 hours

Plug in these values in the formula

Speed =210/3

=70 miles per hour

Hence, if a train travels 210 miles in 3 hours moving at a constant speed then the speed of the train is 70 miles per hour
