Trina uses 8.6 pints of blue paint and white paint to paint her bedroom walls.

max2010maxim [7]

<h3>Trina uses 3.44 or $\frac{ 17.2}{5}$ pints of white paint</h3>

<em><u>Solution:</u></em>

Given that,

Trina uses 8.6 pints of blue paint and white paint to paint her bedroom walls

3/5 of the amount is blue paint, and the rest is white paint

From given,

3/5 of 8.6 pints is blue paint

$Remaining = 1 - \frac{3}{5}\\\\Remaining = \frac{2}{5}$

Thus, 2/5 of 8.6 pints is white paint

<em><u>How many pints of white paint did she use to paint her bedroom walls? </u></em>

$White\ paint = \frac{2}{5} \times 8.6\\\\White\ paint = \frac{17.2}{5}\\\\White\ paint = 3.44$

Thus she uses 3.44 or 17.2/5 pints of white paint

Solve for g gg. Give an exact answer. 10 ( 0.4 + 0.5 g ) = 4 g 10(0.4+0.5g)=4g10, left parenthesis, 0, point, 4, plus, 0, point,

kirill115 [55]

Answer:

the value of g is -4

Step-by-step explanation:

$10 ( 0.4 + 0.5 g ) = 4 g$

Our aim is to solve for g

multiply 10 inside the parenthesis

$4+5g = 4g$

Now combine like terms

Subtract 5g from both sides

$4+5g-5g= 4g-5g$

$4=-g$

Divide both sides by -1

$g=-4$

goblinko [34]

Answer:

$\huge\boxed{A=60\pi cm^2}$

Step-by-step explanation:

The formula of an area of a elipse:

$A=\pi ab$

We have:

$2a=10cm\to a=5cm\\\\2b=24cm\to b=12cm$

Substitute:

$A=\pi\dot5\cdot12=60\pi(cm^2)$
