Answer:
1) 189.25 square inches
2) 21 square feet
Step-by-step explanation:
1) In order to find the area of a semicircle, you use (πr^2)/2. When you plug in 3.14 as pi and 5 as your radius, you'll get 39.25. The area of the rectangle is base x height which is 10 x 15/150. 150 + 39.25 = 189.25
2) If you draw a vertical line that is parallel to the 2 feet measure, you'll have two rectangles with areas (5x3) and (3x2). 15 + 6 = 21

Step-by-step explanation:
6 times 3.14 is 18.84
Given,
Diameter of circle = 6 in.
As we know that radius is half of diameter.
Radius = 6 × 1/2 = 3 inches
Now,
[tex] \sf Circumference \: of \: circle = 2 \pi \: r[/tex]
[tex] = \: 2 \times \dfrac{22}{7} \times 3[/tex]
[tex] = \dfrac{44}{7} \times 3[/tex]
[tex] = \dfrac{132}{7} [/tex]
[tex] = 18.84\: in.[/tex]

What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
It is given that Mr. Ammons is constructing a walkway through his rectangular Garden. The walkway runs diagonally as shown in the diagram.
We need to find the length of the walkway.
Using Pythagoras Theorem;
[tex]15^2 + 24^2 = x^{2} \\\\x^{2} = 225 + 576\\\\x^{2} = 801\\\\x = \sqrt{801} \\\\x = 28.30[/tex]
Therefore, 28.3 ft is closest to the length of the walkway. answer will be Option B. 28.3 ft

how do you write the equation of a line in slope intercept form looking at a table?
Answers
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept
1) Determine the slope (m)
To find the slope, take two points from the table, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] and plug them into the following equation to solve for m:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug m into [tex]y=mx+b[/tex] .
2) Determine the y-intercept (b)
Take any point given in the table and plug them into [tex]y=mx+b[/tex] (along with the slope that you solved for earlier) as [tex](x,y)[/tex]. Solve for b. Plug b back into [tex]y=mx+b[/tex] along with the slope.

Melissa has a total of $250 in her savigns account. She started with $110 and then earned the rest of her savings by babysitting. Melissa charges $7 per hour. Write an equation to represent the situation and determine the number of hours (h) she babysat last week.

Giving the following information:
Net savings (babysitting)= 250 - 110= $140
Rate per hour= $7
To calculate the number of hours that Melissa worked as a babysitter, we need to use the following formula:
Number of hours= net savings / rate per hour
Number of hours= 140 / 7
Number of hours= 20 hours
