Answer:

432 square feet

Step-by-step explanation:

We know perimeter of rectangle is 2(length + width)

we already know that length is 8 yards

and perimeter is 84 feet

we need to find width first

then

we find area of garden by using formula

area of rectangle = length * width

first we need to convert yards into feet as perimeter is in yards

1 yard = 3 feet

8 yards = 3*8 feet = 24 feet

now we plug value of length and perimeter in formula

perimeter = 2(length + width)

84 = 2(24 + width)

84/2 = 24 + width

=> 42 = 24 + width

=> width = 42 - 24 = 18

Thus, width of garden is 18 feet

now

area of the garden = length * width = 24* 18 feet square

area of the garden= 432 square feet

Other way to explain:

perimeter = 2 *length + 2 *width

length = 24 feet (8 yards = 24 feet)

since perimeter = 84 feet

84 = 2 * 24 + 2 * width

36 = 2 * width

18 = width

width = 18 feet

area of rectangle is length * width = 24 * 18 = 432 square feet

A retired woman has $40,000 to invest. She has chosen one relatively safe investment fund that has an annual yield of 9% and ano

nalin [4]

She should invest $30000 in the 9% fund and $10000 in the 13% fund.

Explanation

Suppose, the amount of investment at 9% rate is $x$ dollar.

As the total amount of investment is $40000 , so the investment at 13% rate will be: $(40000-x) dollar$

So, the amount of earnings per year from 9% fund $= 0.09x$ dollar

and the amount of earnings per year from 13% fund $= 0.13(40000-x)$ dollar.

Given that, the total earnings per year is $4000. So the equation will be......

$0.09x+0.13(40000-x)=4000\\ \\ 0.09x+5200-0.13x=4000\\ \\ -0.04x=4000-5200\\ \\ -0.04x= -1200\\ \\ x= \frac{-1200}{-0.04}=30000$

So, the amount of investment at 9% fund is $30000 and the amount of investment at 13% fund = ($40000- $30000)= $10000

Hannah weighed 7.2 pounds at birth. Her weight was recorded at each of her infant doctor visits. The records from her appointmen

lorasvet [3.4K]

Answer:

So If Hannah weighed 7.2 lb at birth during the six months that are shown on the table hanna puts on 8.7 during those six months so if we’re estimating what her weight will be at her one year visit

8.7(what she put on during the six months)+ 15.9 (her weight now)= 24.6

Answer: I estimate she will weigh 24.6lb at her one year visit

6 1/2 chocolate chips and 5/2 cups of flour how many more cups of chocolate chips use than cups of flours

PIT_PIT [208]

Answer: 4

Step-by-step explanation:

Amount of chocolate chips = 6 1/2

Amount of cups of flour = 5/2

The cups of flour should be changes to a mixed fraction and this will be 5/2 = 2 1/2

The question simply means we should find the difference between the fractions given and this will be:

= 6 1/2 - 2 1/2

= 4

Determine wether the function is increasing, decreasing, or constant

evablogger [386]

Answer:

decreasing

Step-by-step explanation:

"Increasing" means the graph is going up from left to right.

"Decreasing" means the graph is going down from left to right.

"Constant" means the graph is "flat" (this is not a technical term) it is keeping the same y value, neither going up nor going down.

What can be super confusing is the

(2.2, 5) mentioned in the question. THIS IS NOT A POINT. It is an interval and points and intervals unfortunately have the same notation sometimes.

An "interval" is a section of the graph, here: FROM 2.2 not including 2.2, TO 5 not including 5. These are like the address on the x-axis. If you look at your graph at 2.2 on the x-axis, it is a peak(relative maximum) and it goes down to the right to where x is 5 where it bottoms out (relative minimum) So on that interval, from 2.2 to 5, the graph is DECREASING.
