3. Here is a diagram of a softball field:
a. About how long is the fence around the field?
Outfield
Infield
b. About how big is the outfield?
110 ft
250 ft
(Hint: You can assume the infield is a circle.)
Answers
a. Length of the fence around the field = perimeter of quarter circle = 892.7 ft.
b. The area of the outfield is about 39,584 sq. ft..
What is the Perimeter of a Quarter Circle?Perimeter of circle = 2πr
Perimeter of a quarter circle = 2r + 1/4(2πr).
a. The length of the fence around the field = perimeter of the quarter circle fence
= 2r + 1/4(2πr).
r = 250 ft
Plug in the value
The length of the fence around the field = 2(250) + 1/4(2 × π × 250)
= 892.7 ft.
b. Size of the outfield = area of the full field (quarter circle) - area of the infield (cicle)
= 1/4(πR²) - πr²
R = radius of the full field = 250 ft
r = radius of the infield = 110/2 = 55 ft
Plug in the values
Size of the outfield = 1/4(π × 250²) - π × 55²
= 49,087 - 9,503
= 39,584 sq. ft.

find the missing angle for the irregular polygon. show your work.
Answers
Answer:
x = 114 , ∠A = 132 , ∠B = 114 and ∠D = 124
Step-by-step explanation:
The polygon has 7 sides
A 7 sided polygon has angles that add up to 900 degrees.
So if we add all the measures of the angles and set it to 900 we can solve for x
900 = x + 18 + 132 + 130 + 130 + x + 10 + 138 + x
step 1 : combine like terms
18+132+130+130+10+138 = 558
x + x + x = 3x
We now have 3x + 558 = 900
step 2 : subtract 558 from both sides
900 - 558 = 342
we then acquire 342 = 3x
step 3 : divide both sides by 3
342 / 3 = 114 and 3x / 3 = x
we're left with x = 114
Now we plug in the value of x into the x's to find the measures of the unknown angles
∠B = x and x = 114 so ∠B simply has a measure of 114°
∠A = x + 18
x = 114
∠A = 114 + 18 = 132°
∠D = x + 10
x = 114
∠D = 114 + 10 = 124°
So we can conclude x = 114 , ∠A = 132 , ∠B = 114 and ∠D = 124
Solve the equation or formula for the indicated variable.
T= 2rπh + 2πr^2; for h
Steps would be much appreciated
Answers
Answer:
h = [tex]\frac{T - 2\pi r^{2}}{2\pi r}[/tex]
Step-by-step explanation:
T= 2rπh + 2πr²
Subtract terms that don't include the indicated variable from both sides:
T= 2rπh + 2πr² ⇒ T - 2πr² = 2rπh
Divide values being multiplied by indicated variable from both sides:
T - 2πr² = 2rπh ⇒ [tex]\frac{T - 2\pi r^{2}}{2\pi r}[/tex] = h

The legs of the right triangles are drawn along the grid lines. You can count the grid lines to see how long they are. Use the given formula to find the square of the hypotenuse, then take the square root. The hypotenuse of each triangle is the straight-line distance between its end points.
It should be no surprise that 3^2 +4^2 is more than 3^2 +3^2, so the length from B to C will be longer than from A to C.

3. If a store had a 20% discount on a coat that was $29.99, how much would you have to pay for the coat?
Answers
Answer:
$23.99
Step-by-step explanation:
$29.99 x 0.2 = 5.998
$29.99 - 5.998 = $23.99
Explanation: Since there is a 20% discount, the coat costs 80% of the original.
As such, 29.99 * 80%= 23.992

Answers
Answer:
2q + 6Step-by-step explanation:
Expand the expression with the help of distributive property.
2(q + 3)=> (2 x q) + (2 x 3)=> 2q + 6Hence, the expanded expression is 2q + 6.
Answer:
2q +6
Step-by-step explanation:
The distributive property is used for this purpose. The factor outside parentheses (2) multiplies each of the terms inside parentheses (q, 3).
2(q +3) = 2·q +2·3 = 2q +6
_____
Additional comment
It might help to think of the parentheses as a "bag" containing one "q" and 3 tokens. The number outside parentheses tells you how many "bags" you have. Expanding the expression is equivalent to dumping out the bags and describing the total contents:
2(q +3) = (q +3) +(q +3) . . . . multiplication is the same as repeated addition
= (q +q) +(3 +3)
= 2q +6

Right now Seth's age is 4/5 the age of his brother Eric. Twenty-one years ago, Eric was twice as old as Seth. What are their ages now?
Answers
Answer:
Present Time
Let X= Eric's age (4/5)X= Seth's age
Question: What are their ages now?________________________________________________________________________
Past (21 years ago)
X-21 =Eric's age (4/5)X-21=Seth's age
2*[4/5(X-21]=Eric's age
Therefore, X-21= 2*[4/5(X)-21]=Eric's age Substitution
_______________________________________________________________________
X-21= 8/5 X - 42 Solve for "X" by adding 42 to both sides.
X-21+42=(8/5) X
X+21 = (8/5)X Subtract "X" from both sides.
21=(3/5)X Multiply both sides of equation by reciprocal of (3/5), which is 5/3
21*(5/3)= X Finish the problem to find value of "X," which is Eric's age.
Then find 4/5 (X)= Seth's age
Seth age = 4/5 × Eric's age
seth age = x
eric age = y
x = 4y/5 .....eqa 1
2(x-21) = y-21 ......eqa 2
2(4y/5 - 21) = y-21
8y/5 - 42 = y -21
8y/5 - y = 21
1.6 y - y = 21
0.6 y = 21
y = 35 years Eric's age
x = 28 years Seth's age
