10x3000

Step-by-step explanation:

Answer: 10 to the power of 3

Answer:

155in³, 465in³

The cone and cylinder have the same height and radius, so the volume of the cylinder is 3 times the volume of the cone.

Step-by-step explanation:

Formula: πr²[tex]\frac{h}{3}[/tex]

Given: π = 3.14, r = 4.6, h = 7

Sub: 3.14(4.6)²[tex]\frac{7}{3}[/tex]

SImplify: 3.14(21.16)[tex]\frac{7}{3}[/tex]

Simplify: (66.4424)[tex]\frac{7}{3}[/tex]

Solve: 155

The volume of the cone is 155in³

Formula: (πr²)h

Given: π = 3.14, r = 4.6, h = 7

Sub: (3.14(4.6²))7

Simplify: (3.14(21.16))7

Simplify: (66.4424)7

Solve: 465

The volume of the cylinder is 465.

Since the last term of the cone is 1/3 of the last term of the cylinder, we can say:

The cone and cylinder have the same height and radius, so the volume of the cylinder is 3 times the volume of the cone.

Answer and Step-by-step explanation:

We are given functions that show how much Frank gets payed at his two jobs.

To find his total pay, we must add the functions together.

T(x) = f+g(x) = 10x + 8x + 12

Add together 10x and 8x.

T(x) = 18x + 12

We get the answer to be:

C. T(x) = 18x + 12

Answer:

[tex]Area = 216\pi[/tex]

Step-by-step explanation:

Given

See attachment for semicircles

Required

The area of the paper

First, calculate the area of each petal.

The petal is made up of:

1. Semicircle of diameter 12cm

2. Semicircle of diameter 18cm (i.e. 12cm + 6cm)

3. A hole semicircle of diameter 6cm

The area of each semicircle is calculated as follows:

[tex]Area = \frac{\pi r^2}{2}[/tex]

For (1):

[tex]d = 12cm[/tex] --- diameter

[tex]r = 0.5 * d = 0.5* 12cm = 6cm[/tex] --- radius

So:

[tex]A_1 = \frac{\pi * 6^2}{2}[/tex]

Evaluate the exponent

[tex]A_1 = \frac{\pi * 36}{2}[/tex]

Divide 36 by 2

[tex]A_1 = 18\pi[/tex]

For (2):

[tex]d = 18cm[/tex]

[tex]r = 0.5* 18cm = 9cm[/tex]

So:

[tex]A_2 = \frac{\pi * 9^2}{2}[/tex]

[tex]A_2 = \frac{\pi * 81}{2}[/tex]

[tex]A_2 = 40.5\pi[/tex]

For (3):

[tex]d = 6cm[/tex]

[tex]r = 0.5* 6cm = 3cm[/tex]

So:

[tex]A_3 = \frac{\pi * 3^2}{2}[/tex]

[tex]A_3 = \frac{\pi * 9}{2}[/tex]

[tex]A_3 = 4.5\pi[/tex]

Recall that (3) is a hole.

So, the area (A) of a petal is:

[tex]A = A_1 + A_2 - A_3[/tex]

[tex]A = 18\pi + 40.5\pi - 4.5\pi[/tex]

[tex]A = 54\pi[/tex]

The paper uses 4 petals.

So:

[tex]Area = 4 * A[/tex]

[tex]Area = 4 * 54\pi[/tex]

[tex]Area = 216\pi[/tex]

Answer:

Step-by-step explanation:

Simplify this problem by dividing all three terms by 2:

x^2 + 20 = -4x

Rewrite this in standard form:

x^2 + 4x + 20

Take the coefficient of the x term and divide it by 2:  4/2 = 2

Square this result:  2^2 = 4

Between x^2 + 4x  and  20  add this 4, then subtract it:

x^2 + 4x + 4 - 4

Rewrite x^2 + 4x + 4 as the square of a binomial:

(x + 2)^2 - 4, or (x + 2)^2 = 4

Answer:

Pay for 40 hours would be [tex]\geq 40 * 148[/tex]

Step-by-step explanation:

Gabe works for 4 hours and earns $ 1,120

Pay for one hour is [tex]\frac{1120}{4} = 280[/tex]

When he works for 10 hours, he earns $1480.

Pay for one hour is

[tex]\frac{1480}{10} = 148[/tex]

Thus the per hours pay must be greater than or equal to 148 dollars

Pay for 40 hours would be [tex]\geq 40 * 148[/tex]

Answer:

Brian's rate is 15 km/hr

Adrian's rate is 16 km/hr

Step-by-step explanation:

Let r = Brian's rate

   r + 1 = Adrian's rate

4/r = Brian's time

4/(r + 1) = Adrian's time

The difference in times is 1 min = 1/60 hr

[tex]\frac{4}{r} - \frac{4}{r + 1} = \frac{1}{60}[/tex]     LCD = 60r(r + 1)

4(60)(r + 1) - 4(60)r = r(r + 1)

240r + 240 - 240r = [tex]r^{2}[/tex] + r

[tex]r^{2}[/tex] + r - 240 = 0

(r - 15)(r + 16) = 0

r = 15    or   r = -16

Since the rate cannot be negative, Brian's rate is 15 km/hr and Adrian's rate is 16 km/hr

Fraction of time that the Snowy Pines get at least 14 inches of snow is 1/4.

Box plot, which is also known as box and whisker plot, is a method of graphically representing the measures like minimum, maximum and the quartiles of the data set.

Given is a box and whisker plot.

We know that box plot represents the first quartile, median and third quartile of the data set.

First quartile is where the 25% of the data points lie.

Median is where the 50% of the data points lie.

Third quartile is where 75% of the data points lie.

Above 14 inches lie the third or upper quartile.

75% of the data points lies below 14.

Data points which are at least 14 inches is 14 or more than 14.

Snowy Pines get at least 14 inches of snow for 100% - 75% = 25% of data points.

Fraction = 25/100 = 1/4

Hence the required fraction of time is 1/4.

3:4:5 = 3+4+5=12

2. Out of the ratio we know that Colin gets 5 parts which is 5/12

3. If we subtract 5/12 from 1/3 we should get an answer of 1/12

5/12-1/3 =1/12
