y equals to 31
Step-by-step explanation:
6(5) = 30
30+1 = 31
Answer:
Step-by-step explanation:
Translate the verbal statements into a system of linear equations: Fatima invested a total of $1000 in two simple-interest bank accounts. One account paid 5% annual interest; the other paid 6% annual interest. The total amount of interest she earned after 1 year was $56
Simple interest formula =
I = PRT
We are to find the Amount = Principal invested
For Account 1
I1 = P × 5% × 1
= 0.05P
Account 2
I2 = P × 6% × 1
= 0.06P
Therefore:
0.05P + 0.06P = $56
Answer:
90
Step-by-step explanation:
0.4/0.3=1.3
1.3 is the answer
You have to divide 4/10 and 1/3 and what ever two answers you get from there is the two that you divide
Answer: Choice C) 41.13 square meters
---------------------------------------------------------------------------------------------
This figure is a composition of two quarter-circles and a square
Area of quarter circle = (1/4)*(area of circle)
Area of quarter circle = (1/4)*(pi*r^2)
Area of quarter circle = (1/4)*(pi*4^2)
Area of quarter circle = (1/4)*(pi*16)
Area of quarter circle = (1/4)*16*pi
Area of quarter circle = 4pi
There are two quarter circles, so the two circular areas add to 4pi+4pi = 8pi
Area of square = s*s = 4*4 = 16 square meters
Add the square area to the circular area: 8pi+16
Now use a calculator to find 8pi+16 = 41.1327412287183 which rounds to 41.13
