Answer:

10859.94

Step-by-step explanation:

To solve this, you need to know the formula for solving the area of a circle: πr²

The first thing you should do is find the area of the square: 78 x 78 = 6084

Then, we find the area of the circle. To do this, we must figure out the radius. Luckily, the problem states that the combined diameter of both half circles is 78, which means the radius is 39. Then, we can apply the formula: π39².

39² = 1521

1521 x 3.14 = 4775.94

This is the combined area of both half circles.

Finally, we have to add: 4775.94 + 6084 = 10859.94

A scale on a hiking map shows that 1.5 inches represents 4 miles
Alexxandr [17]

Answer: 24 miles.


Step-by-step explanation:

1. You must keep on mind that, according the scale on the map, 1.5 inches represents 4 miles. Then, you can set up the following ratio:

\frac{1.5}{4}=\frac{6}{x}

Where x is the number of actual miles asked

2. You must solve for x, as following:

(1.5)(x=4*6\\x=\frac{24}{1.5}\\x=16

3. Therefore, 6 inches on the map represents 24 miles.

A missile is fired at an angle of 75 from the horizontal. At one point, its speed was 900 mph. Find its horizontal velocity in m
mezya [45]

Hello  Chrisd117991999.

If the missile was going 900mph and we are trying to find the horizontal velocity

This could be 3.88, and rounding it to the nearest hundredth would be <u><em>3.90 miles per minute</em></u>

Identify the solution to the following inequality: -1/2 (x+3) &gt; x - 3
mrs_skeptik [129]

Answer:

A

Step-by-step explanation:

- \frac{1}{2} (x + 3) > x - 3 ( multiply both sides by 2 to clear the fraction )

- (x + 3) > 2x - 6 ← distribute parenthesis on left side by - 1

- x - 3 > 2x - 6 ( subtract 2x from both sides )

- 3x - 3 > - 6 ( add 3 to both sides )

- 3x > - 3

divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity

x < 1
