A circle is a curve sketched out by a point moving in a plane. The measure of the angle is 72°.
And, The measure of the angle is 126°.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
Now, Let the angle that turns through 1/5 of the circle be x.
We know that the measure of the center of a circle is 360°, while it is given that the angle turns through 1/5 of the circle.
Therefore, the angle will turn 1/5 of 360°.
⇒ x = 1/5 × 360°
⇒ x = 72°
Thus, the measure of the angle is 72°.
And, For angle that turns through 3/5 of a circle.
The value of angle is,
⇒ x = 3/5 × 360°
⇒ x = 216°

Simplify the expression (5k^2)^3
(5k^2)^3 simplifies to 125k^6.
To simplify the expression (5k^2)^3, we can apply the exponent rule. The rule states that when raising a power to another power, we multiply the exponents together.
In this case, we have (5k^2)^3. To simplify, we raise both the base, 5, and the exponent, k^2, to the third power.
First, let's raise the base, 5, to the third power:
5^3 = 5 x 5 x 5 = 125
Next, let's raise the exponent, k^2, to the third power:
(k^2)^3 = k^(2 x 3) = k^6
Therefore, (5k^2)^3 simplifies to 125k^6.

Use the net as an aid to compute the surface area of the triangular prism. A) 550m^2 B) 614m^2 C) 670m^2 D) 790m^2
Answer:
The correct answer is option D. 790 m²
Step-by-step explanation:
Formula:-
Area of triangle = bh/2
Area of rectangle = bh
where b - Base and h - Height
To find the area of prism
Area of prism = Base area + side rectangle area + side triangle area
= (16 * 11) + (2 * 11 * 17) + (2 * 16 * 15 /2)
= 176 + 374 + 240
= 790 m²
Therefore the correct answer is option D. 790 m²
The surface area of the triangular prism is 790m². ( option D)
A triangular prism is a type of prism with triangular base. The surface area of a prism is expressed as ;
SA = 2B + ph
where , B is the base area and p is the perimeter of the base.
Base area = 1/2bh
where b is the base and h is the height
= 1/2 × 16 × 15
= 8 × 15
= 120m²
Perimeter = 17 + 16 + 17 = 50m²
Surface area = 2 × 120 + 50 × 11
= 240 + 550
= 790 m²
Therefore, the surface area of the prism is 790m²
find the area of the composite figure... please help
Answer:
27.5 square yards
Step-by-step explanation:
So, we have two shapes connected together and we want to know the combined area of the two. All we have to do is find out the area of each one, then add the results.
First, the rectangle:
The area of a rectangle is the base multiplied by the height, so
A = 6 x 4 = 24 square yards
Then, the half-circle.
We know the area of a circle is calculated with A = π * r², so the area of a half circle will be A = (π * r²)/2.
We know the circle has a diameter of 3 yards because the wall next to it is also 3 yards and the whole structure is 6 yards wide, so...
A = (π (1.5)²)/2 = 2.25 π / 2 = 3.53 square yards
Overall, we have
Area of the rectangle: 24 square yards
Area of the half-circle: 3.53 square yards
Total: 27.53 square yards, rounded to the tenth: 27.5 square yards.
Answer:
27.5 yards^2
Step-by-step explanation:
We are given a figure which comprises of two shapes: a rectangle and a semicircle and we are to find the area of this composite figure.
We know that the area of these two shapes is given by the following formulas so we will put in the given values to get:
Area of rectangle = [tex]length \times width[/tex] = [tex]6 \times 4[/tex] = 24 yd^2
Area of semi-circle = [tex]\frac{\pi r^2}{2}[/tex] = [tex]\frac{3.14 \times 1.5^2}{2}[/tex] = 3.53 yd^2
Area of composite figure = [tex]24+3.53[/tex] = 27.5 yards^2

In a survey 3/4 of 400 parents said yes, they give their children fruit snack. How many answered yes to the survey?
300 parents
3/4 = x/400, and we are trying to find x.
Multiply the numerator and denominator of 3/4 each by 100 to make the denominator equal 400. This gives 300/400. So, 300/400 = x/400.
Multiply both sides of the equation by 400 to cancel out the division. This gives you 300 = x, so 300 parents said yes to the survey.

Answer:
Mean : 95
Median : 85
Mode : 90
Part B : Impossible
Step-by-step explanation:
We can make an equation to find the mean using the first 5 history test scores.
[tex]85=\frac{80+75+90+75+95+n}{6} \\ \\ 85=\frac{415+n}{6} \\ \\ 510=415+n \\ \\ n=95[/tex]
So a 95 would be needed to have a mean of 85.
Next, the median.
First, we sort the first 5 history scores from least to greatest.
We get 75, 75, 80, 90, 95.
Since, 80 is the middle value, it will be used in the calculation of the median.
We can make an equation with this.
[tex]82.5=\frac{80+n}{2} \\ \\ 165=80+n \\ \\ n=85[/tex]
So a score a 85 would be needed to have a median of 82.5
Thirdly, the mode.
Since 90 is already in the set once, we can just have Maliah score another 90 to make 90 the mode (with the exception of 75 of course).
Finally, Part B.
We can use the equation we had for the first mean calculation but change 85 to 90.
[tex]90=\frac{80+75+90+75+95+n}{6} \\ \\ 90=\frac{415+n}{6} \\ \\ 540=415+n \\ \\ n=125[/tex]
So Maliah would need a score of 125 to make her mean score 90, but since the range is only from 0-100, it is impossible.

Find the surface area and volume of cone. A = rs + r2 V = 1/3r2 h A cone's slant height (s) is 14 cm and its radius is 4.5 cm. Surface area (to the nearest tenth) = cm2 Volume (to the nearest tenth) = cm3
Answer:
Surface area = [tex]261.6cm^2[/tex]
Volume = [tex]281.2cm^3[/tex]
Step-by-step explanation:
To find the surface area of our cone, we are using the formula for the surface area of a cone:
[tex]A=\pir(r+\sqrt{h^2+r^2} )[/tex]
where
[tex]A[/tex] is the surface area
[tex]r[/tex] is the radius
[tex]h[/tex] is the height
Notice that the height, radius, and slant height make a right triangle, so to find the height, [tex]h[/tex], we can use the Pythagorean theorem:
[tex]s^2=r^2+h^2[/tex]
[tex]14^2=4.5^2+h^2[/tex]
[tex]196=20.25+h^2[/tex]
[tex]h^2=196-20.25[/tex]
[tex]h^2=175.75[/tex]
[tex]h=\sqrt{175.75}[/tex]
[tex]h=13.26[/tex] cm
We have all we need now to find the surface area of our cone:
[tex]A=\pir(r+\sqrt{h^2+r^2} )[/tex]
[tex]A=\pi(4.5)(4.5+\sqrt{13.26^2+4.5^2} )[/tex]
[tex]A=261.6cm^2[/tex]
Now, to find the volume of our cone, we are using the formula for the volume of a cone:
[tex]V=\frac{\pi r^2h}{3}[/tex]
where
[tex]V[/tex] is the volume
[tex]r[/tex] is the radius
[tex]h[/tex] is the height
Replacing values
[tex]V=\frac{\pi (4.5^2)(13.26)}{3}[/tex]
[tex]V=281.2cm^3[/tex]
We can conclude that the surface area of our cone is 261.6 square centimeters and its volume is 281.2 cubic centimeters.
Answer:
Surface area [tex]= 261.405 cm^2\\[/tex]
Volume of the cone [tex]= 177.19 cm^3\\[/tex]
Step-by-step explanation:
Slant height of cone [tex]= (r + \sqrt{r^2 + h^2}) \\[/tex]
Height of the cone will be derived from this slant height
[tex]14 = 4.5 + \sqrt{4.5^2 + h^2} \\9.5 = \sqrt{4.5^2 + h^2}\\90.25 = 20.25 + h^2\\h = 8.36\\[/tex]
Surface Area of Cone
[tex]= \pi r (r + l)\\= (3.14) (4.5) (4.5 + 14)\\= 261.405[/tex]
Volume of the cone
[tex]= \frac{1}{3} \pi r^2h\\= \frac{1}{3} (3.14)(4.5^2) (8.36)\\= 177.19 cm^3\\[/tex]

.45 is 1/10 of what decimal?
Answer:
4.5
Step-by-step explanation:
To get the answer, you have to multiply the number 0.45 by the denominator of 1/10. [The denominator is 10.]The reason for this is because 10 is the whole number of parts. When you multiply 1/10 x 0.45, you get 4.5 [Just move the decimal point one place to the right because 10 has one zero.]
To double check your answer, divide 4.5 by 10 or multiply 4.5 x 1/10. Either way you get 4.5, so that's the correct answer.

The length of a rectangle is 2 inches more than its width. The perimeter of the rectangle is 24 inches. The equation 2x + 2(x + 2) = 24, where x is the width in inches, represents this situation. The value of x from the set {1, 3, 5, 7} that holds true for the equation is . So, the width of the rectangle is inches and its length is inches.
Answer:
Width is 5 and length is 7
Step-by-step explanation:
You can solve the equation using the distributive property and inverse operations.
2x +2(x+2)=24
2x + 2x + 4 = 24
4x + 4 = 24
4x = 20
X = 5
This means the width is 5 and the length is 7.
The width of the rectangle is 5 inches and its length is 7 inches.
Explanation:The given equation 2x + 2(x + 2) = 24 represents the situation with a rectangle's length being 2 inches more than its width and the perimeter of the rectangle being 24 inches. To find the value of x from the set {1, 3, 5, 7} that holds true for the equation, we can substitute each value into the equation and solve for x. By trying each value, we find that x = 5 holds true for the equation.
Therefore, the width of the rectangle is 5 inches and since the length is 2 inches more than the width, the length would be 7 inches.

Answer:
204
Step-by-step explanation:
To find the volume of a rectanguar prism, you must multiply legnth x width x height to get the volume.
Before we multiply, first lets convert the fractions into improper fractions to make multiplying a little easier.
6 3/8 = 51/8
10 2/3 = 32/3
Now, we multiply.
[To multiply fractions, multiply the numerators and denominators.]
51/8 x 32/3
51 x 32 = 1632
8 x 3 = 24
1632/24 = 68
Now that we've multiplyed the length and height, multiply 68 by the width, 3.
68 x 3 = 204
Therefore, the volume of the rectangular prism is 204. I hope this helps!

16 is 80% of what number
Answer:
20
Step-by-step explanation:
This reads mathematically exactly how it is stated in words. The word "is" means =, the word "of" means multiply, and "what number" is x. Therefore, the equation from that looks like this: 16 = .80x. Don't forget that you cannot use a percent in an equation without first changing it to its decimal equivalency. Solve that for x by dividing both sides by .80 to get that x = 20
The number that when 80 % is found of it, would give the result of 16 is the number 20.
What is 80 % of 20 ?To determine the number that 16 is 80% of, you can set up an equation using algebra.
Let's represent the unknown number with the variable "x." The equation can be written as:
16 = 80% of x
To solve for "x," we need to isolate it on one side of the equation.
Since 80% is equivalent to 0.8 as a decimal, we can rewrite the equation as:
16 = 0.8x
To solve for "x," divide both sides of the equation by 0.8:
16 / 0.8 = 0.8x / 0.8
Simplifying the equation:
20 = x
Therefore, the number that 16 is 80% of is 20.
