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

Answer:

∠ADC and ∠BDC are supplementary

A pair of complementary angles is angles ACD and DCB.

<ADC and <BDC are supplementary angles

<ACD and <BCD are complementary angles)

Complementary Angles: Two angles that add up to 90 degrees, complementing each other to form a right angle, e.g., 30 and 60 degrees.

Supplementary Angles: Two angles that add up to 180 degrees, forming a straight line, e.g., 120 and 60 degrees.

From the figure

ED is a ray that bisects AB and <ACB

<ACB is 90⁰(given)

<ADC + <BDC = 180( linear angles)

Linear angles are supplementary

Therefore

<ADC and <BDC are supplementary angles

Since <ACB = 90⁰

ED is a bisector

Therefore

<ACD + <BCD = 90⁰

<ACD and <BCD are complementary angles)

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!

It’s C or 34+24=58 so the answer is C

It is c 58 your welcome

Answer:

C

Step-by-step explanation:

The scale factor is a quantity that "scales" another quantity.

Since, the dimensions of large is "3 times" that of the smaller box, the scale factor is 3.

This means, that we can multiply any dimension (length, width, or height) of the small box by 3 to get respective dimension of large box.

Remember, to get area, we need to multiply by scale factor squared. To get volume, we need to multiply by scale factor cubed.

Since, surface area is given of smaller box, we need to multiply by scale factor squared (3^2 = 9) to get surface area of larger box.

Hence, 79 * 9 = 711 cm^2

C is the correct answer.

f(x) is linear

g(x) is exponential

Answer: linear, exponential

Step-by-step explanation:

f(x) the blue line has a constant slope so is a line (linear).

g(x) the red line has an asymptote at x = 0 and has an exponential rate/slope so is exponential.

(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.

Step-by-step explanation:

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.

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.

Answer:

width = (x-1)

Step-by-step explanation:

The volume of the prisms is defined in the problem as

Volume = x^3 + 9x^2 + 6x − 16

Volume  = width*height* length

And we know that,

length = (x+2)

height = (x+8)

We can find the roots of the equation, which happen to be

x = -8

x = -2

x = 1

(See image below)

This means that the volume can be represented as

Volume = x^3 + 9x^2 + 6x − 16 = (x+8)(x+2)*(x-1)

Therefore,

The width = (x-1)

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.

Answer:

3.64

Step-by-step explanation:

65 + 66 + 70 + 58 + 61 = 319

319/5 = 63.8

65 - 63.8 = |1.2|

66 - 63.8 = |2.2|

70 - 63.8 = |6.2|

58 - 63.8 = |-5.8| = 5.8

61 - 63.8 = |-2.8| = 2.8

1.2 + 2.2 + 6.2 + 5.8 + 2.8 = 18.2

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]
