Ella takes 1 3/5 hours to complete a painting. Holly takes 3/4 of the time that Ella takes. How long will Holly take to complete

Misha Larkins [42]

1. you have to figure out what 3/4 of Ella's time is.
$1 \frac{3}{5} = \frac{8}{5}$
(You find that out by multiplying 5x1. Then add 3.)
2. Convert the fractions into decimals. (This will help make it easier when dividing.)
$\frac{8}{5} = 8 \div 5 = 1.6$
$\frac{3}{4} = 3 \div 4 = .75$
3. Next you are going to divide 1.6 by .75
$1.6 \div .75 = 2.13$
4. Now multiple 2.13 by 5.
$2.13 \times 5 = 10.65$
Answer is 10

spin [16.1K]

A={1,2,3,8}

B={x|x is an even whole no less than 9}

B={2,4,6,8}

Now

$\\ \sf\longmapsto A\cap B=\{2,8\}$

Solve in(5x+7)=8 round to the nearest thousandth

Ivan

Answer:

$x=\frac{1}{5}$

$x=0.2$

Step-by-step explanation:

$(5x+7)=8$

$5x+7=8$

Subtract 7 from both sides.

$5x+7-7=8-7$

Simplify.

$5x=1$

Divide both sides by 5.

$\frac{5x}{5} =\frac{1}{5}$

Simplify.

$x=\frac{1}{5}$

Decimal form:

0.2

A wheel spins at 300 revolutions per minute. What is the angular velocity of the wheel, in radians per second? Round the answer

Ostrovityanka [42]

well, this is just a matter of simple unit conversion, so let's recall that one revolution on a circle is just one-go-around, radians wise that'll be 2π, and we also know that 1 minute has 60 seconds, let's use those values for our product.

$\cfrac{300~~\begin{matrix} r \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }{~~\begin{matrix} min \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }\cdot \cfrac{2\pi ~rad}{~~\begin{matrix} r \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }\cdot \cfrac{~~\begin{matrix} min \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }{60secs}\implies \cfrac{(300)(2\pi )rad}{60secs}\implies 10\pi ~\frac{rad}{secs}\approx 31.42~\frac{rad}{secs}$
