5000 principal earning 4% compounded annually, 7 years
almond37 [142]

Answer:

Step-by-step explanation:

Basically, you want to know interest. I = prt is the formula. 'I' will be left blank b/c that's unknown. P is principal, 5000. R is rate, 4%, or 0.04 when turned into a decimal. T is time, 7 years. So now when using the formula, it will all become I = 5000(0.04)(7). What that means is you first multiply 5,000 by 0.04, getting 200. Then when you multiply 200 by 7, it's 1,400, which will leave you with I = 1,400. Interest is 1,400.

2 Nine identical circles are cut from a square sheet of paper whose sides are
Ivanshal [37]

Answer:

278.64cm²

Step-by-step explanation:

Area of the sheet left out = Area of the square - Area of the 9 circles

Area of the square = L^2

L is the side length of the square

A = 36^2

Area of the square = 1296cm^2

Diameter of a circle = 38/3 = 12cm

Area of a circle = πr²

r is the radius = 12/2 = 6cm

Area of a circle = 3.14(6)²

Area of a circle = 3.14 * 36

Area of a circle = 113.04cm²

Area of 9 circles = 9 * 113.04

Area of 9 circles = 1,017.36cm²

Area of the left over = 1296 - 1,017.36

Area of the left over = 278.64cm²

8 less than the product of -3 and a number is greater than -26
Novay_Z [31]

Answer:

x > 6

Step-by-step explanation:

x = the number

we can write an inequality for this equation:

-3x = product of x and -3

-8 = 8 less than

> -26 = greater than 26

inequality:

-3x - 8 > -26

to solve this, we first add 8 to each side to get:

-3x > -18

then we divide both sides by -3 to get:

x > 6

that's your answer!
