Sara takes 1/6 of an hour to vacuum his moms car it takes 4 times that long to wash the car then it takes you to wax the car twi

Nataly [62]

<h2>Answer:</h2><h2>2 hours & 10 minutes </h2><h2>Step-by-step explanation:</h2><h2>1/6 of an hour is 10 minutes. She vacuumed for 10 minutes. It took 4 times as long to wash the car so 10 * 4 = 40. She washed the car for 40 minutes. It took her twice as long to wax the car as it did for her to wash it so 40 * 2 = 80. She waxed the car for 80 minutes. 10 + 40 + 80 = 130 minutes or 2 hours and 10 minutes. </h2>

How can fact families and multiplication facts help you divide

Ksivusya [100]

The fact families you will need to know so you can figure out the answer or answers your multiplication facts will help you because division is backwards multiplication and if you know that 5 x 4 = 20 than you know that 20 divided by 4 = 5

Hoped this helped ;)

Which measures are accurate regarding triangle JKL? Check all that apply.

mixas84 [53]

Answer:

Option (1), (3) and (6) is correct.

m∠K = 84° , k ≈ 3.7 units and KL ≈ 3.2 units.

Step-by-step explanation:

Given : ∠J = 58° , ∠L = 38° and length of side JK = 2.3 units.

We need to check all the options and choose that follows.

First we find the measure of ∠K

Using angle sum property , Sum of angles of a triangle is 180°

⇒ ∠J + ∠k + ∠L = 180°

⇒ 58° + ∠k + 38° = 180°

⇒ ∠k + 96° = 180°

⇒ ∠k = 180° - 96°

⇒ ∠k = 84°

Also using sine rule on ΔJKL , we get,

$\frac{KL}{\sin J}=\frac{JL}{\sin K}=\frac{JK}{\sin L}$

Substitute the values, we get,

$\frac{KL}{\sin 58^{\circ}}=\frac{k}{\sin 84^{\circ}}=\frac{2.3}{\sin 38^{\circ}}$

Consider the last two ratios, we have,

$\frac{k}{\sin 84^{\circ}}=\frac{2.3}{\sin 38^{\circ}}$

${k}=\frac{2.3}{\sin 38^{\circ}}\times {\sin 84^{\circ}}$

On solving we get,

${k}=3.71$

Also, now consider the first and last ratio, we get,

$\frac{KL}{\sin 58^{\circ}}=\frac{2.3}{\sin 38^{\circ}}$

${KL}=\frac{2.3}{\sin 38^{\circ}}\times {\sin 58^{\circ}$

${KL}=3.16$

Thus, k ≈ 3.7 units and KL ≈ 3.2 units.

Option (1), (3) and (6) is correct.

Put 50%, 2/25, 5, and 0.31 in order from greatest to least

storchak [24]

Answer:

$5,50\%,0.31,\frac{2}{25}$

Step-by-step explanation:

we have

50%, 2/25, 5, and 0.31

1) 50%

we know that

$50\%=\frac{50}{100}$

2) 2/25

Multiply by 4/4

$\frac{4}{4}(\frac{2}{25})=\frac{8}{100}$

3) 5

Multiply by 100/100

$\frac{100}{100}(5)=\frac{500}{100}$

4) 0.31

Multiply by 100/100

$\frac{100}{100}(0.31)=\frac{31}{100}$

Now all numbers have the same denominator

so

$\frac{500}{100}> \frac{50}{100}>\frac{31}{100}>\frac{8}{100}$

therefore

$5 > 50\%>0.31>\frac{2}{25}$

$5,50\%,0.31,\frac{2}{25}$
