$1\% =\frac{1}{100}\\ \\25 \ \% * x =60\\ \\ \not25^1*\frac{1}{\not100^4}x = 60 \\ \\\frac{1}{4}x =60 \ \ /*4\\ \\x=60*4\\ \\ x=240$

jeka57 [31]

X : the gas used by first car in 1 particular week
y : the gas used by second car in 1 particular week
$x + y = 60 \\ x = 60 - y$
$30x + 35y = 1975 \\ 30 \times (60 - y) + 35y = 1975 \\ ... \\ y = 35 \\ x = 60 - y = 60 - 35 = 25$

Calculate the perimeter for the parallelogram if a= 7.6 , b= 5.9 and c= 14.6

kolezko [41]

Although the problem gives the value of b, it's really not needed.

Opposite sides of a parallelogram are congruent, so we just need to calculate: 2a + 2c = P

Plug the given values in:

2 * 7.6 + 2 * 14.6 = 44.4 units, or choice (C).

Find the volume of a box that has a length of 7 cm, a width of 9 cm, and a height of<br> 11.2 cm.

astra-53 [7]

The answer is 705.6 cm^3.

Remember that volume of a box, rectangular prism, is: V = LWH.

So, V = 7(9)(11.2) = 705.6 cm^3
