Answer:

1256, 125.6 (this is wrong sorry i didn't know that it wasn't a full circle)

Step-by-step explanation:

A) The area that the sprinkler is spraying is in a circle with a radius of 20 ft. The formula to find the area of a circle is pi*r^2, so the area of this circle will be 400pi (substitute 20 for r). Pi in this problem is 3.14, so 400*3.14 is 1256 feet.

B) The perimeter of the spray is technically just the circumference of the circle. The circumference is 2r*pi, so we substitute 20 for r again and we get 40pi. Again, pi is 3.14 in this problem, so 40*3.14 is 125.6 feet.

the function F is defined by F(x) 12/x+1/2. use this formula to find the following values of the function. F(a/2)

Answers

Subtract 1/2 by F(x) then multiply by 12

Answer:

F([tex]\frac{a}{2}[/tex]) = [tex]\frac{24}{a} +\frac{1}{2}\\[/tex]

Step-by-step explanation:

so basically what you want to do is insert the f(x) value into the equation. What I mean by that is in this equation, since f(x) = f(a/2), you want to substitute A/2 into the equation, so you'll have [tex]\frac{12}{\frac{a}{2} }[/tex], if you can't see that, its 12/a/2. In other words, this is 12 ÷ [tex]\frac{a}{2}[/tex] , which you can also format as 12 ·[tex]\frac{2}{a}[/tex], because of the "keep, change, flip" thing. Well, you know that equation is equal to 24/a so you just have to add back the 1/2, and you have your answer!

you basically do whatever the questions tell you right? if you’re stuck on one just search it up without the “you”
okay so what you do here, mean is when you all all these numbers together and then divide them by the number of numbers here but because they want the difference between these two, you will take whatever you get after you added all them up then divided them by the total amount of number. then you take those two numbers and minus them and that will give you, your answer.
let me work it out for you
56+47+67+77+55+76+85+80+87+69+47+58
=804
divide that by the total numbers you have in the table that is, 12 numbers
so 804 divided by 12 gives you
=67
let me do the next one
52+32+65+63+52+70+72+61+54+43+29+32
=652
then you take that 652 and divide it by the total numbers given in the table which is also 12
so 652 divided by 12
=that’s 54,3
then you take the final answers
67-54,3
and your final answer is 12,7

Wyatt makes and sells rope doormats. He uses 200 feet of rope for each doormat. He wants to make 25 doormats.

Which expression shows a correct way to find how many yards of rope he needs?

1 yard = 3 feet
Group of answer choices

200×25×3

200×25÷3

200÷25×3

200÷25÷3

Answers

200x25(divided)3

That’s because when you find out 200x25 (5000) it will still be in feet and not yards. 1 yard is 3 ft so you would divide your 5000 feet by 3 to change it to yards!
It’s 200x25x3 because he is using 200 feet of rope for each mat and he wants to make 25 of them so that means that is a multiply.Then each yard is 3 feet witch means that it’s multiplying again.

which is the measure of ∠DBC?

Answers

Answer: 20°

Step-by-step explanation:

There is 180 degrees in the triangle.  ∠C is 50°,  ∠A is 80°,  ∠B is 30°, and the total adds up to 160°, so 180-160 equals 20.

Answer: 20 degrees

Step-by-step explanation: if you add up the angles of any triangle, the sum should always be 180. so add up angle A and angle C :

80 + 50 = 130

subtract that from 180 to find out what angle ABC is:

180 - 130 = 50

since we know that angle ABD is 30 degrees, all we have to do now is subtract that from 50:

50 - 30 = 20

angle DBC = 20 degrees

Can someone answer this its just boxplots :)))

Answers

Answer:   50%

Explanation:

The boxplot, aka box-and-whisker plot, is a visual way to represent summary data. Each piece of the boxplot visually tells us one of the five items of a five number summary, which are:

Min = smallest valueQ1 = first quartileMedian = middle most valueQ3 = third quartileMax = largest value

The median is the vertical line inside the box of the boxplot. The diagram shows that the median is 25. Exactly half of the distribution is below the median, and the other half is above the median. So that means that 50% of the cars get at least 25 mpg.

Andre is making paper cranes to decorate for a party. He plans to make one large paper
crane for a centerpiece and several smaller paper cranes to put around the table. It takes
Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will
only have 30 minutes to make the paper cranes once he gets home.

1. Andre wrote the inequality to plan his time. Describe what , , 10,
and 30 represent in this inequality.

2. Solve Andre’s inequality and explain what the solution means.

Answers

Answer:

10 + 3x </= 30

x </= 6.666

He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.

Step-by-step explanation:

10 + 3x </= 30

10 is the minutes for the centerpiece

3 is the minutes to make each small crane

x is the number of small cranes he can make

he has less than or equal to 30 minutes to complete them.

10 + 3x </= 30

subtract 10 from both sides

3x </= 20

x </= 6.666

He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.

Find the value of x - this is circle segments.


Answers

Answer:

x = 12

Step-by-step explanation:

Given a tangent and a secant from an external point to the circle, then

The square of the tangent is equal to the product of the external part of the secant and the entire secant, that is

x² = 8(8 + 10) = 8 × 18 = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12

The answer should be x=12!
