Answer:
[C] 25π square inches
Step-by-step explanation:
Given that:
the long hand of the clock is about 5 inches long.
To Find:
What is the approximate area of the clock face?
Solve:
Formula - A =πr²
Note that;
π = 3.14 (about)
Radius - 5 inches
A =πr²
A = 3.14(5)²
A = 3.14(25)
A = 78.5
Now let see the answer choices:
A. 5π square inches ≈ 5(3.14) = 15.7
B. 10 π square inches ≈ 10(3.14) = 31.4
C. 25 π square inches ≈ 25(3.14) = 78.5
D. 100 π square inches ≈ 100(3.14) = 314
Hence, the answer is [C] 25 π square inches

Kai bought 3 1/8 pounds of ground beef, 1 3/4
pounds of sausage, and some ground turkey for a chili cook-off. He bought 6 pounds of meat total. How much ground turkey did he buy?
A. 1 1/2 pounds
B. 1 1/8 pounds
C. 4 1/2 pounds
D. 4 7/8 pounds
Answer:
B. 1 1/8 pounds
Step-by-step explanation:
What we know:
6 Pounds of meat in total
3 1/8 pounds of ground beef
1 3/4 pounds of sausage
Combining the pounds of ground beef and sausage together:
3 1/8 + 1 3/4 = 4 7/8
In all he has 6 pounds of meat. He we know the combined weight of the ground beef and sausage combined: 4 7/8 pounds. Therefore, the equation is...
6 - 4 7/8 =
The answer is...
B. 1 1/8 pounds
Answer:
B. 1 1/8 pounds.
Step-by-step explanation:
Let the weight of turkey he bought be x pounds.
Then we have the equation:
x + 3 1/8 + 1 3/4 = 6
x = 6 - 3 1/8 - 1/ 3/4
Converting to improper fractions
x = 6 - 25/8 - 7/4
We could use a calculator to do this but it also can be done manually by converting all amounts to fractions with denominator 8:
x = 48/8 - 25/8 - 14/8
= 9/8
= 1 1/8 pounds.

Find the surface area of the pyramids
first one:
The surface area of a pyramid can be found using the formula:
Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area
Since the side lengths of the base are equal, the perimeter of the base is:
Perimeter of Base = 4 x Side Length
Perimeter of Base = 4 x 9 = 36 feet
To find the slant height, we can use the Pythagorean theorem:
Slant Height^2 = Height^2 + (1/2 x Side Length)^2
Slant Height^2 = 12^2 + (1/2 x 9)^2
Slant Height^2 = 144 + 20.25
Slant Height^2 = 164.25
Slant Height = 12.81 feet
The base area can be found using the formula for the area of a square:
Base Area = Side Length^2
Base Area = 9^2 = 81 square feet
Plugging in the values into the formula for surface area:
Surface Area = (1/2) x 36 x 12.81 + 81
Surface Area = 218.16 square feet
So the surface area of the pyramid is 218.16 square feet.
second one:
The surface area of a pyramid can be found using the formula:
Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area
Since the side lengths of the base are equal, the perimeter of the base is:
Perimeter of Base = 4 x Side Length
Perimeter of Base = 4 x 8 = 32 meters
To find the slant height, we can use the Pythagorean theorem:
Slant Height^2 = Height^2 + (1/2 x (Side Length1 + Side Length2))^2
Slant Height^2 = 3.5^2 + (1/2 x (8 + 4))^2
Slant Height^2 = 12.25 + 36
Slant Height^2 = 48.25
Slant Height = 6.94 meters
The base area can be found using the formula for the area of a square:
Base Area = Side Length^2
Base Area = 8^2 = 64 square meters
Plugging in the values into the formula for surface area:
Surface Area = (1/2) x 32 x 6.94 + 64
Surface Area = 107.52 square meters
So the surface area of the pyramid is 107.52 square meters.
please help, i dont understand an ounce of this
Let x be the length of each side of the nonagon. We then split up the nonagon into 9 congruent, isosceles triangles, each with base = x and height = 12. Then the area of each triangle is 1/2 • x • 12 = 6x, so the total area of the nonagon will be 9 • 6x = 54x.
To find x, we can use some facts from geometry and trigonometry.
• In any polygon, the sum of the measures of the exterior angles is 360°. So each of these exterior angles will measure 360°/9 = 40°.
• Exterior angles are supplementary to the interior angles. So each interior angle will measure 180° - 40° = 140°.
• Each of the 9 triangles are isosceles with base angles measuring half the interior angles of the nonagon, 140°/2 = 70°.
• Cut the triangle in half along the labeled inradius of the nonagon, which has length 12. In the resulting right triangle, we have
tan(70°) = 12 / (x/2)
and solving for x gives
tan(70°) = 24/x
x = 24/tan(70°)
x = 24 cot(70°) ≈ 8.7
Then the total area of the nonagon is
54x = 54 • 24 cot(70°) ≈ 471.7

How to make Mixed fractions into Improper Fractions?
Easy!
What you do is, you multiply the denominator with the whole number, then add the result of multiplying the denominator with the whole number to the numerator, and then, when you have that result, you put that result as your new numerator, and the denominator remains same from the Mixed fraction.

The population of 150,000 decreases each year by 150
Since the population is decreasing it would be -150 iguana's
[tex]\frac{-150 iguanas }{1 year}[/tex]
Answer: A
Step-by-step explanation:
facts
there are 150,000 iguanas. each year, we lose 150.
The rate of change is a fixed amount of something increasing or decreasing in a certain amount of time. Since the population loses 150 iguanas each year, the rate of change, or unit rate, is -150 (if it decreases, its negative).

154 in²3168/7 km²38.5 m²Revising the area of a circle formula
We already know that the area of a circle is expressed as [tex]\pi r^{2}[/tex].
The "r" variable is known as the radius.Solving each problem given:Solving Problem 4:We are given the radius of circle, which is 7 in. Let us substitute the radius in the formula. Once substituted, we can simplify the expression obtained to determine the area of the circle shown in the picture.
[tex]\implies \pi (7)^{2}[/tex]
Take π as 22/7
[tex]\implies \huge\text{(}\dfrac{22}{7} \huge\text{)}(7)^{2}[/tex]
[tex]\implies \huge\text{(}\dfrac{22}{7} \huge\text{)}(7)(7)[/tex]
[tex]\implies (22)(7)[/tex]
[tex]\implies 154 \ \text{in}^{2}[/tex]
Solving Problem 5:In this problem, we are given the diameter to be 24 kilometers. Since the radius of the circle is half the diameter, we can tell that the radius of the circle is 24/2 kilometers, which is 12 kilometers.
[tex]\implies \pi (12)^{2}[/tex]
Take π as 22/7
[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (12)^{2}[/tex]
[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (12)(12)[/tex]
[tex]\implies \dfrac{3168}{7} \ \text{km}^{2}[/tex]
Solving Problem 6:We are given the radius of circle, which is 3.5 in. Let us substitute the radius in the formula. Once substituted, we can simplify the expression obtained to determine the area of the circle shown in the picture.
[tex]\implies \pi (3.5)^{2}[/tex]
Take π as 22/7
[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (3.5)^{2}[/tex]
[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (3.5)(3.5)[/tex]
[tex]\implies \huge\text{(}\dfrac{22}{2}\huge\text{)} (3.5) = (11) (3.5)[/tex]
[tex]\implies 38.5 \ \text{m}^{2}[/tex]

The Garza family uses about 12,000 kWh/year. If they install a wind turbine whose rotor has a diameter of 20 ft, the formula relating annual energy output to annual average wind speed, V, in mph, becomes 12,000=0.01328⋅202⋅V3, which simplifies to 12,000=5.312V3.
Solve 12,000=5.312V3 for V. With a rotor whose diameter is 20 ft, what is the annual average wind speed that the Garzas need to power their home?
Enter your answer into the box. Round to the nearest tenth.
V =
mph
Answer: V = 13.1 mph
Step-by-step explanation:
12,000 = 5.312V^3
Divide 5.312 from both sides, and on the right side it will cancel out.
12,000/5.312 = V^3
2,259 = V^3
Extract the cube roots of both sides, leaving V^3 to just V.
13.1 = V (I think)
