Answer:
Length = 17 cm
Width = 8 cm
Step-by-step explanation:
Let the length be x cm
Therefore, Width = (x - 9) cm
Perimeter of rectangle = 2(l +w)
50 = 2[x + (x - 9)]
50/2 = 2x - 9
25 = 2x - 9
25+ 9 = 2x
2x = 34
x = 34/2
x = 17 cm
x - 9 = 17 - 9 = 8 cm
Therefore,
Length = 17 cm
Width = 8 cm
Thus, the dimensions of the rectangle are 17 cm and 8 cm.

<u />
<u>Compound Interest Formula</u>

where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- n = number of times interest applied per time period
- t = number of time periods elapsed
Given:
- A = $17,474.00
- P = $7,790.00
- r = 15% = 0.15
- n = 12
- t = number of years
Substitute the given values into the formula and solve for t:






Therefore, the money was in the account for 5 years and 5 months (to the nearest month).
Answer:
21/32 square inches.
Step-by-step explanation:
The area of a rectangle = length x width
The area of her picture = length x widht
= 7/8 x 3/4
= 21/32
The area of her picture is 21/32 square inches.
Yes, I agree the area of the picture is 21/32 square inches.
The area must be in square inches. So she need to specify it.
Thank you.
Answer:D) 1 hr
Step-by-step explanation:
Given
Pump A and B can fill tank in 
Pump A and C can fill tank in 
Pump B and C can fill tank in 
Let A be the total hr taken A therefore rate of 
Let B be the total hr taken B therefore rate of 
Let C be the total hr taken C therefore rate of 
-----1
-----2
-----3
Adding 1,2 & 3



thus time taken by A,B and C combined is 1 hr
