Answer:

63

Step-by-step explanation:

She finds her average resting heart rate to be 62 after  5 days.

That means, average of the 5 heart rate pulse=62

If the last day was 58 and all the other days were the same.

Let x be her pulse on the other days,

Then,

Average, 62=\dfrac{58+4x}{5}\\\text{Cross Multiply}\\58+4x=62 X 5\\\text{Suntract 58 from both sides}\\4x=(62X5)-58\\4x=310-58\\4x=252\\\text{Divide both sides by 4}\\x=63

Her pulse on all the other days is 63.

Ari is designing a patio that will be 20 feet long and 16 feet wide. He makes a scale drawing of the patio using a scale of 1 in
Anna007 [38]

Answer:

80 square feet

Step-by-step explanation:

This time I will get it right for sure!

So first we need to find the area in feet, and then convert it in to inches.

1) Since the patio has the shape of a rectangle, then the formula is:

A = a * b

A = 20 * 16

A = 320 feet

2). Now we have to find the ratio, so:

320 / 4 = 80

So, the answer is

1 square inch to 80 square feet.

Hope this helps))

vekshin1

Answer: $180,000

Step-by-step explanation:

Gross Domestic Product (GDP) is the total monetary value of all finished goods and services made within a country during a specific period. It can be used to estimate the size and growth rate of the country's economy.

In the case above Company X sell leather which is not a finished good to Company Y, so it will not contribute to the gross domestic product (GDP). Company Y sells leather shoes which is a finished good to the consumers, which will contribute to the GDP.

Therefore the total contribution to GDP is $180,000
