Let x is Jiri's age
2x is Pamela's age

x + 2x = 33
3x =33
x = 33/3
x =11
Answer: Jiri's age is 11

Jiri's age is 11 because x + 2x is 3x... 3x =33 and then when you divide it, you get 11

What’s the correct answer for this question?

podryga [215]

Answer:

Step-by-step explanation:

Circle with centre (0,2) will have the equation

(x)²+(y-2)² = r²

Finding r² by distance formula using P(-7,2)

r² = (-7-0)²+(2-2)²

r² = (-7)²

r² = 49

So substituting in the equation

x²+(y-2)² = 49

To avoid mildew and mold, Clay's new oat barn has an open shaft lengthwise through the barn with small holes drilled throughout

Nadusha1986 [10]

Answer:

Therefore, Clay can order 1,776 cubic feet of oats.

Step-by-step explanation:

To determine how many cubic feet of oats the barn can hold, break the barn up into three sections, the rectangular prism that makes up the bottom section of the barn, the triangular prism that makes up the top of the barn, and the rectangular prism that makes up the shaft.

The rectangular prism that makes up the bottom section of the barn is 12 feet wide, 16 feet long, and 8 feet high. Use the formula for the volume of a rectangular prism to find the volume.

Therefore, the volume of the bottom rectangular prism is 1,536 cubic feet.

The triangular prism that makes up the top section of the barn is 12 feet wide, 4 feet high, and 16 feet long. Use the formula for the volume of a triangular prism to find the volume.

Therefore, the volume of the top triangular prism is 384 cubic feet.The rectangular prism that makes up the shaft through the barn 3 feet wide, 3 feet high, and 16 feet long. Use the formula for the volume of a rectangular prism to find the volume.

Therefore, the volume of the shaft is 144 cubic feet.

The total volume available to store oats is the volume of the bottom section plus the volume of the top section minus the volume of the shaft.

There are 5,280 feet in one mile. How many feet are there in 6 miles?

ella [17]

You simply multiply
5280*6= 31680

So your answer would be 31,680 ft in 6 miles

Hope this helps!<span />

E) Natasha's parents want to support Natasha by saving $5000 for her college. They searched up for some investment options and c

Bas_tet [7]

Answer:

Amount she would have in 2 years at a simple interest of is

$5000 + ($5000 x 0.048 x 2) = $5480

Amount she would have in 2 years at a 4.1 % / year compounded semi- annually is :

$5000 x ( 1 +0.041/2)^4 = $5422.78

the first option yields a higher value in two years when compared with the second option. Thus, the first option is the best one to choose

Step-by-step explanation:

Future value with simple interest = principal + interest

Interest = principal x interest rate x time

0.048 x 5000 x 2 = 480

future value = $480 + 5000 = $5480

The formula for calculating future value with compounding:

FV = P (1 + r)^nm

FV = Future value

P = Present value

R = interest rate

m = number of compounding

N = number of years

5000 x ( 1 + 0.041 / 2)^(2 x 2) = $5422.78
