What is 70 X 12 1/2?

gulaghasi [49]

Answer:

70 x 12 1/2 = 875.

Step-by-step explanation:

Step 1.) When you multiply fractions, you put whole numbers over one.

Step 2.) Then, you change whole numbers with fractions, to improper fractions.

Step 1.)

70/1 x 12 1/2

Step 2.)

70/1 x 25 / 2.

And then we solve!

70 x 25 = 1750

1 x 2 = 2.

1750 divided by 2 = 875.

Hope this helps!!

Solve for x. −3/4x≥12 Will name brainliest!

Anuta_ua [19.1K]

<em>Answer:</em>

<em></em> $\boxed{x \leq -16}$ <em></em>

<em>Step-by-step explanation:</em>

<em></em> $(-\frac{3}{4})^{(x)} \geq 12$ <em></em>

<em>Simplify both sides of the inequality.</em>

<em></em> $\frac{-3}{4} x \geq 12$ <em></em>

<em>Multiply both sides by 4/(-3).</em>

<em></em> $(\frac{4}{-3}) * (\frac{-3}{4}x) \geq (\frac{4}{-3}) * (12)$ <em></em>

<em></em> $= x \leq -16$ <em></em>

<em>Hope this helped you!</em>

Tina has two rectangular playpens to keep her new pet dogs. The first rectangle has a width of 6 feet and a length of x - 4 feet

denpristay [2]

Answer:

4x+24 ft.

Step-by-step explanation:

Perimeter of first rectangular playpen mentioned: 2(6+x-4), which can be simplified to 2(x+2) = 2x + 4.

Perimeter of second playpen mentioned: 2(8+x+2), which can be simplified to 2(x+10) = 2x+20.

Add these two together: 2x+4 + 2x+20 = 4x+24. Don't forget to add units: 4x+24 ft.

Ainat [17]

Cost of aluminum required to make a ball of radius 7.5 inches is $ 161.71

<h3><u>Solution:</u></h3>

Given that

Goran's company makes solid balls out of scrap metal for various industrial uses.

For one project, he must make aluminum balls that have a radius of 7.5 inches.

Cost of aluminum = $0.12 per cubic inches

Need to determine cost of aluminum to make one ball.

Lets first calculate the volume of one ball

As shape of the ball is sphere , we can use volume of sphere formula

$\text {Volume of ball }=\text { Volume of sphere }=\frac{4}{3} \pi r^{3}$

Where "r" is the raius of ball

Given that radius of required ball = 7.5 inches

$\text { So, volume of ball of radius } 7.5 \text { inches }=\frac{4}{3} \pi \times 7.5^{3}$

$=\frac{4}{3} \times 3.14 \times 321.875=1347.5833 \text { cubic inches }$

So quantity of aluminum required is same as volume of ball = 1347.5833 cubic inches

Cost of aluminum for 1 cubic inch = $0.12

<em><u>So cost of aluminum required to make a ball of aluminium of 1347.5833 cubic inches is given as:</u></em>

$=0.12 \times 1347.5833=\$ 161.71$
