Kevin plans to put concrete on a rectangular portion of his driveway the portion is 10 feet long and 3 inches high the price of

Fudgin [204]

First we need to know the total volume of concrete used:
$V_total = \frac{cost_{total}}{cost{unit}}$
$V_total = \frac{\$72.98}{\frac{\$90}{yd^{3}}}$
$V_total = 0.7407yd^{3}$

Now we can use the formula for volume of a rectangular prism:
$V=lwh$
Convert everythig to yards and substitute:
$0.7407yd^{3}=(3.33yd)(w)(0.08333yd)$
$w=\frac{0.7407}{3.33 \times 0.08333}$
$w \aprox 2.66yd$

The measures of three angles are (2x)°, (3x)° , and (x+60)°. what is the value of x?

ratelena [41]

Well combine:
2x + 3x + x + 60 = 180
combine like terms:
6x + 60 =180
then move the 60:
6x = -120
now divide both sides by 6:
x= -20
i hope this helped! :)
