The table shows the amount earned for washing cars. How much is earned for washing 25 cars? 3 cars=$13.50, 6 cars=$27, 9 cars=$4

katrin2010 [14]

You need to find out how much it costs to wash one car, so:

3×=13.50
Divide both sides by 3.
x=4.5 per car.
Now multiply 4.5 by 25 which should give you $112.50

Multiply. 32√⋅28√⋅3√⋅6√ in simplest radical form, in the box.

PolarNik [594]

Answer: $48\sqrt{7}$

Step-by-step explanation:

Given expression, $\sqrt{32} \times \sqrt{28}\times \sqrt{3}\times \sqrt{6}$

= √(4×8)×√(4×7)×√3×√(3×√2)

= √4×√8×√4×√7×√3×√3×√2 ( because √(m×n)=√m×√n)

=√4×√4×√8×√2×√7×√3×√3

=4×√(4×2)×√2×√7×3

=4×√4×√2×√2×√7×3

=4×2×2×√7×3

=48√7

Thus, $\sqrt{32} \times \sqrt{28}\times \sqrt{3}\times \sqrt{6}$ = $48\sqrt{7}$

May I please receive help???? <br> Please

zheka24 [161]

Answer:

43°

Step-by-step explanation:

<h2><u>Equation:</u></h2>

<u />

m∠ABD = m∠1 + m∠2

Substitute:

68° = m∠1 + (m∠1 + 18°)

<h2><u>Solve:</u></h2>

68° = m∠1 + (m∠1 + 18°)

68° = 2(m∠1) + 18°

50° = 2(m∠1)

25 = m∠1

<h2><u>Solution:</u></h2>

<u />

Know that we know that m∠1 is, we can add 18* to find m∠2

25° + 18° = 43°

Fiber One Bran Cereal boasts that it contains 57% of the Daily value of fiber you need. If 1 serving contains 14 grams of fiber,

Makovka662 [10]

The amount of fiber needed in a day is 7.98 grams

<h3>Proportions</h3>

Proportions are parts, in comparative relation to a whole.

In other words, proportions are fractions of a larger dataset

The given parameters from the question are given as:

Proportion of the daily value of fiber needed = 57%
Daily serving = 14 grams.

<h3>Amount of fiber</h3>

The amount of fiber needed in a day is the product of the proportion and the size of the daily serving.

So, we have:

$Amount = 57\% \times 14g$

$Amount = 7.98g$

Hence, the amount of fiber needed in a day is 7.98 grams
