Answer: The formula for the volume of a cone is V = 1/3 b × h... b is the area of the base of the cone. The base of the cone is a circle, so we have to use the area of a circle formula... A = pi × radius^2 So first let's find the area of the base... a = pi × radius^2 a = 3.14 × 12^2 (diameter is 24 so radius is 12) a = 3.14 × 144 a = 452.16 in^2 Now we can plug that into the volume of a cone formula... v = 1/3 b × h v = 1/3×452.16 in^2 × 10 in v = 150.72in^2 × 10 in V = 1507.2 in^3

Allie answered 72% of the questions on her math test correctly. If she answered 18 questions correctly, how many questions were on the test?

Answers

Answer:

25 questions

Step-by-step explanation:

The answer to this question can be solved by setting up a proportion, or equivalent ratios (fractions). Since we know that 18 questions was equal to 72% correct on the test, we can set up a proportion to find the total number of questions:

$(72)/(100)=(18)/(x)$ , where 'x' represents the total number of questions (or 100%) of the questions on the test.

Cross-multiply and divide: 72x = 18(100) or 72x = 1800

Divide both sides by 72: 72x/72 = 1800/72

Solve for x: x = 25 questions

Which of these points lies on the line described by the equation below?y - 4 = -2(x - 6)

A. (-6, -4) B. (-4,-6) C. (6,4) D. (4,6)

Answers

Answer:

Option C is correct.i.e., ( 6 , 4 ) lie on given line.

Step-by-step explanation:

Given Equation, y - 4 = -2 ( x - 6 )

Option A:

From given point, x = -6 and y = -4

LHS = y - 4 = -4 - 4 = -8

RHS = -2 ( x - 6 ) = -2 ( -6 - 6 ) = -2 × ( -12 ) = 24

LHS ≠ RHS

⇒ This point does not lie on given line.

Option B:

From given point, x = -4 and y = -6

LHS = y - 4 = -6 - 4 = -10

RHS = -2 ( x - 6 ) = -2 ( -4 - 6 ) = -2 × ( -10 ) = 20

LHS ≠ RHS

⇒ This point does not lie on given line.

Option C:

From given point, x = 6 and y = 4

LHS = y - 4 = 4 - 4 = 0

RHS = -2 ( x - 6 ) = -2 ( 6 - 6 ) = -2 × ( 0 ) = 0

LHS = RHS

⇒ This point lie on given line.

Option D:

From given point, x = 4 and y = 6

LHS = y - 4 = 6 - 4 = 2

RHS = -2 ( x - 6 ) = -2 ( 4 - 6 ) = -2 × ( -2 ) = 4

LHS ≠ RHS

⇒ This point does not lie on given line.

Therefore, Option C is correct.i.e., ( 6 , 4 ) lie on given line.

Find the area of a square with a side of 20 cm

Answers

Answer:

80 cm

Step-by-step explanation:

This is because the shape is a square, and area is width x height x length.

Since the shape is a square, all sides are the same therefore the answer is 80 cm.

Need help.How to do it. Or could someone answer it.Thanks

so the sheet is called: sets of real numbers
you have the sets
1.natural numbers
2. whole numbers
3. integers
4. rational numbers
5. irrational numbers

1. Natural number: counting numbers not including zero ex. 1,2,3,4...
2. whole numbers: natural numbers and zero ex. 0,1,2,3,4...
3. integers: whole numbers and their negative counterparts ex. -4,-3,-2,-1,0,1,2,3,4...
4. rational numbers: numbers that can be expressed as a/b where b is not equal zero ex 1/4, 3/1, 0/9...
5. irrational numbers: numbers that don't end ex. pi, (note, 0.3333333333333 doesn't count since it can be expressed as 1/3)

so we calculate them and put them into the proper set

1. -15
this is negative, so it is an integer

2. 11
this is a counting number so it is a natural number

3. squarerootof 30
if you calculate this you get a long number. I am not sure weather it ends or not so it could be irrational

4. 17/3
this is rational since it is in the form a/b

5. 6
this is counting so it is natural number

6. 0
this is a whole number

7. -13
this is negative, so it is an integer

8. 3
this is a counting number so it is anatural number

9. 10/11
this is rational since it is in theform a/b

10. 14
this is a counting number so it is anatural number

11. -13
we did this already on no.7
it's an integer

12. pi
this is irrational

13. 475/325
this is rational since it is in theform a/b

14. squarerootof 77
if you calculate this you get a longnumber. I am not sure weather it ends or not so it could beirrational

15. 6/7
this is rational since it is in theform a/b

16. squarerootof 0
this is a whole number because swuareroot of zero=zero

17. -squareroot 196
this is an integer since if you calculate it, it gives you -13

18. -1
this is negative, so it is an integer

so the answers are
1. Integer
2. Natural
3. Irrational
4. Rational
5. Natural
6. Whole
7. Integer
8. Natural
9. Rational
10. Natural
11. Integer
12. Irrational
13. Rational
14. Irrational
15. Rational
16. Whole
17. Integer
18. Integer
