Answer:

Volume of sphere A = 128x (Approx.)

Step-by-step explanation:

Given:

Radius of sphere A = 2 x Radius of sphere B

Volume of sphere B = 16x

Find:

Volume of sphere A

Computation:

Volume of sphere = (4/3)(π)(r)³

Volume of sphere B = (4/3)(π)(r)³

16x = (4/3)(π)(r)³

16x = (4/3)(22/7)(r)³

16x = (88/21)(r)³

Radius of sphere B = 1.56∛x Approx.

Radius of sphere A = 2 x Radius of sphere B

Radius of sphere A = 2 x 1.56∛x

Radius of sphere A = 3.12∛x Approx.

Volume of sphere A = (4/3)(π)(r)³

Volume of sphere A = (4/3)(22/7)(3.12∛x)³

Volume of sphere A = (88/21)(30.37∛x)

Volume of sphere A = 127.27x

Volume of sphere A = 128x (Approx.)

Which information about the coordinates of G and H will prove that GH is a median of AABC?

Annette [7]

Answer:

G (3,-4) ; H (8,1)

Step-by-step explanation:

Midpoint formula:

(x₁ + x₂ / 2 , y₁ + y₂ / 2)

For G (Points B and A):

(3 + 3 / 2 , 1 + (-9) / 2)

(6/2 , -8 / 2)

(3,-4)

For H (Points B and C):

(3 + 13 / 2 , 1 + 1 / 2)

(16 / 2 , 2 / 2)

(8,1)

40% of the children in a sports club play badminton. 25% of the children who play badminton also play squash. There are 11 child

Keith_Richards [23]

Answer:

There are 110 children total in the sports club

Step-by-step explanation:

To get this answer, its actually easier than it seems. You might need a calculator however.

First you start with the 11 children who play both badminton and squash, then, you divide that by 0.25 (25%) to get 44.

Next you take 44 and divide it by 0.4 (40%) to get 110.

And there you go! If you want to make sure you got it right simply start with 110 and multiply it by 0.4 then multiply the number/decimal you get by 0.25. You should get 11 to confirm your answer :)

A pilot and co-pilot are performing a test run in a new airplane. The pilot is required to take off and fly in a straight path a

Using the slope concept, it is found that:

The minimum horizontal distance is of 14,281.5 feet.

The maximum horizontal distance is of 15,398.6 feet.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>.

It's also the tangent of the angle of depression.

In this problem, the vertical change is the altitude of 10,000 feet.

The minimum horizontal distance is with an angle of 35º, hence:

$\tan{35^{\circ}} = \frac{10000}{d}$

$d = \frac{10000}{\tan{35^{\circ}}}$

$d = 14281.5$

The maximum horizontal distance is with an angle of 33º, hence:

$\tan{33^{\circ}} = \frac{10000}{d}$

$d = \frac{10000}{\tan{33^{\circ}}}$

$d = 15398.6$

The attendance at a baseball game was 400 people. Student tickets cost $2 and adult tickets cost $3. Total sales were $1050. How

S_A_V [24]

We know the total tickets sold = 400. Let x be the number of adult tickets sold. That means 400 - x is the number of student tickets. The revenue from adult tickets will be $3 * x, which we can call 3x. The revenue from student ticks will be $2 * (400 - x), or 800 - 2x. The total revenue is $1050, so that means: 3x + (800 - 2x) = 1050. Removing the parentheses: 3x + 800 - 2x = 1050 Subtracting 800 from both sides: 3x - 2x = 250 Simplifying the left side: x = 250, which is the number of adult tickets. 400-x = student tickets = 400-250 = 150. ALWAYS check! In this case, check the revenue: 3x = 3(250) = 750 2(150) = 300 750 + 300 = 1050. Check!
