Anyone know how to do this?? I need help plss!!! Tyyy!!

Answer:

75.4yd

Step-by-step explanation:

Find the diagram attached

Perimeter of the figure = perimeter of the 4 semicircles

Perimeter of a semicircle = πd/2

d is the diameter of the semicircle = 12yd

Perimeter of a semicircle = 3.14(12)/2

Perimeter of a semicircle = 37.68/2

Perimeter of a semicircle = 18.94yd

Perimeter of the 4 semicircles = 4 * 18.94

Perimeter of the 4 semicircles = 75.36yd

Hence the perimeter of the swimming pool to nearest tenth is 75.4yd

Answer:

D. 30 Ft.

Step-by-step explanation:

Split the trapezoid into two shapes for an easier process .

The ideal split shall result in two shapes: A rectangle and a right triangle .

Rectangle Formula: L · W = A

Substitution: 6 · 4 = 24 Ft.

Right Triangle Formula: ( B · H )  ÷ 2 = A

Substitution: ( 3 · 4 ) ÷ 2 = 6 Ft.

Add the separate areas together to get the final result .

24 + 6 = 30 Ft.

Answer:

Cubic Inches

Step-by-step explanation:

I hope this helps you.

Answer:

104 degrees

Step-by-step explanation:

The whole shape will come to 360 degrees, so if you add 126 degrees and 26 degrees it will come to 152 degrees. You then subtract 152 degrees fro. 360 degrees, this will give you 208 degrees. Then you divide 208 degrees by 2 that results in 104 degrees. So 104 degrees is the answer.

Answer:

65 degrees

Step-by-step explanation:

90 - 25 = 65

Answer and Step-by-step explanation:

To find x, we need to subtract all of the other angles from 180.

180 - 25 = 155

155 - 90 (that's the right angle) = The answer is 65.

The other way to find x is be subtracting 25 from 90, since 25 and x, when added together, forms a right angle, which is 90.

Answer:

56 rabbits

Step-by-step explanation:

Given that  t represents the time, and weeks, and P(t) is the population of the rabbits and that the population doubles every 6 weeks.

In 126 days, there are

= 126/7

= 18 weeks

It means that the rabbit population will double

= 18/6 times

= 3 times

Since there are currently 7 rabbits at the end of 6 week,

P(6) = 7 * 2

= 14

At the end of 12 weeks

P(12) = 14 * 2 = 28

At the end of 18 weeks

P(18) = 28 * 2 = 56

Hence there will be 56 rabbits at the end of 126 days

Given:

The principal value = $10,000

Rate of interest = 8.5% compounded monthly.

To find:

The amount of money in the account in 15 years.

Solution:

The formula for amount is:

[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]

Where, P is principal, r is the rate of interest in decimal, n is the number of times interest compounded in an year, t is the number of years.

Number of months in an year is 12. So, n=12.

Substitute [tex]P=10000, r=0.085, n=12, t=15[/tex] in the above formula.

[tex]A=10000\left(1+\dfrac{0.085}{12}\right)^{12(15)}[/tex]

[tex]A=10000\left(\dfrac{12.085}{12}\right)^{180}[/tex]

[tex]A=35626.53335[/tex]

[tex]A\approx 35626.53[/tex]

Therefore, the amount of money in the account in 15 years is $35626.53.

Answer: 4PCL3 -> P4 + 6CL2

Step-by-step explanation:

So a slope of 1/4 means that for every 4 steps you take forward, you would go up 1.

With this, beginning at the point (6,3), lets take 4 steps back and go down 1. This is instead of going forward, as that value would be outside of your graph We would end up at (2,2). By using these two points, you can graph your line.

Answer:

A. 320 cubic centimeters

Step-by-step explanation:

First, you want to multiply 4 by 4 to get 16. Then what you want to be is multiply 16 by 20 and you will get 320 cubic centimeters.

Answer:

options C -x^2/3z

Step-by-step explanation:

this is the correct answer after we cancelled them

Answer:

C

Step-by-step explanation:

This requires you to know the law of quotient for exponents. For this I recommend separating everything with the same variable into its own fraction to make it easier so you have (-2x^4/6x^2), (y^2/y^2), (z/z^2). Then to simplify you divide the coefficients and signs like normal but for the exponents, you subtract the exponent of the numerator from the denominator. This gives

(-x^2 / 3), (1), and ( 1/z), which you can multiple together to get c.

Hope this helps. Ask if you need me to clarify something.

Answer:

B Is the answer

Step-by-step explanation:

I think

Answer:

(4, 11) is one ordered pair  and (-4, 27) is the other ordered pair

Step-by-step explanation:

(1)  f(x) = x^2 - 2x + 3             (2)    f(x) = -2x + 19

-2x + 19 = x^2 - 2x + 3

x^2 - 16 = 0

(x - 4)(x + 4) = 0

x = 4   or    x = -4                                  -2(4) + 19 = 11

                                                             -2(-4) + 19 = 27

So, when x = 4, y = 11                   and when x = -4, y = 27

(4, 11) is one ordered pair              and (-4, 27) is the other ordered pair

Answer:

The cylinder with a height of 7.0 cm and a diameter of 10.0 cm

Step-by-step explanation:

v = πr²h

---------------------

cylinder with a height of 10.0 cm and a diameter of 7.0 cm

v = π(3.5²)10

v = 384.65 cm³

cylinder with a height of 7.0 cm and a diameter of 10.0 cm

v = π(5²)7

v = 549.5 cm²

549.5 > 384.65

[tex]V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}][/tex] or [tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

Step-by-step explanation:

Given

[tex]Ratio = \frac{\pi}{4}[/tex]

See attachment for complete question

Required

Determine the volume of the cone

The volume of a square pyramid is:

[tex]V = \frac{a^2h}{3}[/tex]

Where

a = base dimension

From the attachment, the base dimension of the square pyramid is 2r.

So:

[tex]a = 2r[/tex]

The volume becomes;

[tex]V = \frac{(2r)^2h}{3}[/tex]

To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.

So, we have:

[tex]V_2 = Ratio * V[/tex]

[tex]V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}][/tex]

[tex]V_2 = \frac{\pi}{4} * \frac{(2r)^2h}{3}[/tex]

Open bracket;

[tex]V_2 = \frac{\pi}{4} * \frac{4r^2h}{3}[/tex]

Cancel out 4

[tex]V_2 = \pi * \frac{r^2h}{3}[/tex]

The above can be written as:

[tex]V_2 = \frac{1}{3} * \pi r^2h[/tex]

[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

So, we have:

[tex]V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}][/tex]

or

[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

Answer:

Step-by-step explanation:

the number of bowls was 6 times the number of plates.

b = 6p

He made 90 bowls during the week.

90 = 6p

p = 15

He made 15 plates during the week.

Answer: c. When the number of pieces is 0, the predicted price is $1.20. This interpretation is not meaningful because a set cannot have 0 pieces

Step-by-step explanation:

The y-intercept in a regression equation shows the value of y when x is 0. For this scenario therefore, the y-intercept is the predicted price of a set when the number of pieces in the set is 0. As the y-intercept is 1.20, this means that when there are no pieces in the set, the predicted price is $1.20.

This however is not logical or meaningful because a set cannot have 0 pieces and if it did, it wouldn't make sense for somebody to pay $1.20 for it.

When the number of pieces is 0, the predicted price is $1.20.

This interpretation is not meaningful because a set cannot have 0 pieces.

We have given that,

Market researchers were interested in the relationship between the number of pieces in a brick-building set and the cost of a set.

regression analysis is a set of statistical processes for estimating the relationships between a dependent variable and one or more independent variables.

The y-intercept in a regression equation shows the value of y when x is 0. For this scenario, therefore, the y-intercept is the predicted price of a set when the number of pieces in the set is 0. As the y-intercept is 1.20, this means that when there are no pieces in the set, the predicted price is $1.20.
