The diameter of a professional baseball mound is 18 feet. The radius of a little league baseball mound is 5 feet. What is the difference in the areas?
Answers
Answer:
175.93 feet
Step-by-step explanation:
First, you divide 18 by 2 to get the radius which is 9. Then you do nine squared. Lastly, you do 64 times 3.14 to get 254.47 (rounded)
Now, you do 5 squared which is 25. Then you multiply 25 by 3.14 to get 78.54 (rounded).
Now you subtract
254.47 - 78.54 = 175.93
Note: I rounded these in the example, the decimal places still go on so the rounded answers may not subtract to the correct answers because all the decimal points weren't shown, but the answer is correct.

Solve for the missing variables. (Geometry)
Answers
Step-by-step explanation:
we are using the right triangle altitude theorem. it means that in a right-angled triangle the geometric mean of the two segments of the Hypotenuse (the baseline opposite of the 90° angle) equals the altitude.
in other words
h² = p×q
h = height
p, q are the 2 segments of the Hypotenuse.
so, in our case we have
100 = x(x + 21) = x² + 21x
that gives us the following quadratic equation
x² + 21x - 100 = 0
the general solution to a quadratic equating is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 21
c = -100
so,
x = (-21 ± sqrt(21² - 4×1×-100))/(2×1) =
= (-21 ± sqrt(441 + 400))/2 = (-21 ± sqrt(841))/2 =
= (-21 ± 29)/2
x1 = (-21 + 29)/2 = 8/2 = 4
x2 = (-21 - 29)/2 = -50/2 = -25
x2 would give us negative lengths for the triangle, which does not make sense.
so, x = 4 is our solution.
that makes the segments of the Hypotenuse 4 and (4+21) = 25 units long (the whole baseline is then 4+25 = 29).

Answer: question one equals one mile and 206 feet. the second question equals 29 yards and 1 foot. the third question equals 2 miles and 25 yards.
Step-by-step explanation: one mile equals 5280 feet. 5486-5280= 206, so 1 mile and 206 feet.
one yard equals 3 feet. 29 x 3= 87, so there are 29 yards and 1 foot.
one mile equals 1760 yards. 1760 x 2= 3520. 3545-3520= 25, so there are 2 miles and 25 yards.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Dascha is making a decorative table to sell at a fair. The cost of her materials is $80. If the table sells for $150, what is the percent of markup?
Answers
Answer:
Step-by-step explanation:
120
.80 x 150 = 120
Explanation
So to solve for the percent of markup you have to minus the price of the product your selling to the cost of the materials then divide by the cost of the materials and multiply by 100 then you get your answer
150-80=70
70/80=0.875
0.875 • 100 = 87.5%

Answer:
228
Step-by-step explanation:
[Formulas Below]
Surface area means the sum of all the shapes on the figure, which means we have to calculate each area of the shapes on the triangular right prism and add them up. To calculate the triangles, we plug in 6 and 5 and get 15. Since there are 2 triangles, we multiply it by 2. Next, we have to find the areas of the rectangles. 11 * 6.5 = 71.5 (There are two of them so you multiply by 2), and 11 * 5 = 55. Finally, we add all of these up. 15 * 2 + 71.5 * 2 + 55 = 30 + 55 + 143 = 228. The surface area is 228.
Area of Triangle = (Length * Height)/2
Area of Rectangle = Length * Width

so Y = 1/3x + 2

Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Answer:
108 centimeters
Step-by-step explanation:
Given that :
Scale model used for the Eiffel Tower :
2 centimeter represents 6 meters;
This means 2 centimeters on the model represents 6 meters of the Eiffel Tower.
To obtain the height of the model in centimeter :
Let the height of the model = h
h of model = actual height of tower
Actual Height of tower = 324 meters
Using cross multiplication :
2 = 6
h = 324
6 * h = 324 * 2
6h = 648
h = 648 / 6
h = 108
Hence, height of the model = 108 centimeters
Answer: 108 centimeters
Step-by-step explanation:
2 centimeters represents 6 meters;
This means 2 centimeters on the model represent 6 meters of the Eiffel Tower.
Let the height of the model = h
h of the model is = to the actual height of the tower
Actual Height of tower = 324 meters
2 = 6
h = 324
6 x h = 324 x 2
6h = 648
h = 648 divided by 6
h = 108
