Answer:

Step-by-step explanation:

Formula: $V = \frac{4}{3}$ πr³, r = d/2

Given: π = 3.14, d = 4

Sub: V = 4/3(3.14)r³, r = 4/2

Find r.

r = 4/2

Solve: r = 2

Sub: V = 4/3(3.14)2³

Simplify: V = (4.18)8

Solve: V = 33.44

For a sale, a store decreases its prices on all items by 25%. An item that costs $120 before the sale now costs $120 - 0,25($120

Alexxandr [17]

Answer:

$Cost = \$120 * 1 - \$120 * 0.25$

Step-by-step explanation:

Given

$Cost = \$120 - 0.25(\$120)$

Required

Solve using distributive property

$Cost = \$120 - 0.25(\$120)$

$\$120$ can be rewritten as $1(\$120)$

So:

$Cost = 1(\$120) - 0.25(\$120)$

Factorize:

$Cost = \$120(1 - 0.25)$

Now, we can apply distributive property on the expression;

$Cost = \$120 * 1 - \$120 * 0.25$

Hence, the above is an equivalent expression.

Solving further, we have

$Cost = \$120 - \$30$

$Cost = \$90$

Step-by-step explanation:

Let

h-----> the high of the balloon

we know that

In the right triangle of the figure

$tan(63\°)=\frac{4}{h}$

$h=\frac{4}{tan(63\°)}$

$h=2.04\ miles$

What’s x to 5x+2 is greater than 3x+10

katovenus [111]

<h2>The value of x is always grater than 4.</h2><h3>Therefore x = (4,∞)</h3>

Step-by-step explanation:

Given

5x+ 2 >3x+10

⇔5x - 3x >10-2

⇔2x > 8

⇔x > 4

<h3>The value of x is always grater than 4.</h3><h3>Therefore x = (4,∞)</h3>
