Answer:

= 6.5 dollars per book

Step-by-step explanation:

This is a fraction equal to

13 dollars ÷ 2 books

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.

A contractor bought 8.2 ftsquared of sheet metal. She has used 3.5 ftsquared so far and has $141 worth of sheet metal remaining

Aleks [24]

Answer:

The cost of a sheet metal per square foot is $30

Step-by-step explanation:

Given

Size of Sheet Metal = 8.2ft squared

Used Sheet Metal = 3.5ft squared

Worth of leftover sheet = $141

Equation: $8.2x - 3.5x = 141$

Required

Find the cost per square foot of the sheet metal

Solving for x in the above equation will give the cost per square foot of the sheet metal.

$8.2x - 3.5x = 141$

$4.7x = 141$

Divide both sides by 4.7

$\frac{4.7x}{4.7} = \frac{141}{4.7}$

$x = \frac{141}{4.7}$

$x = 30$

Hence, the cost of a sheet metal per square foot is $30

3400 in scientific notation

qwelly [4]

3400 in scientific notation

To write 3200 in scientific notation we put a decimal after first digit

All whole numbers have decimal point at the end

3400.

Move decimal point three places to the left

so it becomes 3.400

When we move 3 places to the left we multiply $10^3$

$3.4 * 10^3$

3400, scientific notation is $3.4 * 10^3$

help me if you can...20-22 the midpoint M and one endpoint of GH are given. find the coordinates of the other endpoint.

kenny6666 [7]

Midpoint

x = (x1 + x2)/2

y = (y1 + y2)/2

19)

x = (x1 + x2)/2 = (5 + 4 )/2 = 4.5

y = y = (y1 + y2)/2 = (-6 + 3)/ 2 = -3/2= -1.5

Answer: Midpoint (4.5, -1.5)

20)

x = (x1 + x2)/2 = (-3 -2 )/2 = -2.5

y = y = (y1 + y2)/2 = (7 + 5)/ 2 = 6

Answer: Midpoint (-2.5, 6)

21)

x = (x1 + x2)/2 = (-2 + 8 )/2 = 3

y = y = (y1 + y2)/2 = (9 + 0)/ 2 = 4.5

Answer: Midpoint (3, 4.5)

22)

x = (x1 + x2)/2 = (-4 - 13/2 )/2 = -5.25

y = y = (y1 + y2)/2 = (1 - 6 )/ 2 = -2.5

Answer: Midpoint (-5.25, -2.5)
