I turned the percent into a decimal (.15) then I multiplied the decimal by 50 and got 57.50.
Answer:
on 55 gallons of gas , you can drive 3,190 miles....the cars gas mileage 58 mpg or miles per gallon
49/2= 24.5
Z=24.5
Since you need to get rid of the 2 just divide 49 by 2 and that's what Z equals
N = first integer
n + 1 = second integer
n + 2 = third
n + 3 = fourth
the sum is 114 so:
n + (n + 1) + (n + 2) + (n + 3) = 114
solve:
4n + 6 = 114
4n = 108
n = 27
so 27 is your first.
27 + 1 is your second (remember n +1 n +2 and n +3)
so your first four integers are: 27 28 29 and 30
(I'll also help with one)
week one: x
week two: x + 5
week three: 2(x+5) or 2x + 10
week1 + 2 + 3 = 431
so its:
x + (x+5) + (2x + 10)
4x + 15 = 431
4x = 416
x = 104
its then:
week one: 104 sold
week two: 109 sold (x + 5)
<span>week three: 218 (2x + 10)

A couple wanted to install a square mirror that has:
Area of the mirror = 500 square inches.
x = nearest tenth of an inch , length of wood needed
s = sides of square
Area = s2
500 (area) = s2 | √
x = √500
=> √ 5 x 100
=> √ 5 x √100
=> 10 √ 5
=> approximately 22.4
Since we’re looking for the nearest tenth of decimal place value, the answer is approximately 22.4
