Noah has a toy that requires 4 batteries. Noah buys batteries with a chance of lasting more than 2/3 hours, and he wants to estimate the probability that at least one of the 4 batteries in his toy will go dead before 15 hours are up. Noah wants to use a spinner with equal-sized sections to represent each battery’s chance of lasting more than 15 hours. He will use red sections to represent a battery that dies before 15 hours are up and green sections to represent batteries that last more than 15 hours. How many of each section should Noah have in his spinner? Explain.

Answer:

Pyramid: In fact, the volume of any pyramid is one-third the area of the base times the height. Finding the surface area of a pyramid is done by first finding the area of the base and the area of each lateral face. … Lastly, the surface area of a pyramid is the sum of the area of the base and the lateral area!

Cone: a volume of 4 3 π r 3 \frac{4}{3} \pi r^3 34πr3 and a surface area of 4 π r 2 4 \pi r^2 4πr2.

Sphere: A cone is essentially a pyramid with a circular base. The volume of a pyramid is given by Vpyramid=Abase⋅h3. Since the area of the base of a cone is πr2, the formula for the volume of a cone is Vcone=πr2h3.

Answer:

16 quarters and 1 dime

17 coins in all

Step-by-step explanation:

quarter = .25

.25+.25+.25+.25=1

.25+.25+.25+.25=1

.25+.25+.25+.25=1

.25+.25+.25+.25=1

dime = .10

1+1+1+1+.10= $4.10

Answer:

2, 49, 63

Step-by-step explanation:

multiply x by 7 to get y

Answer:

1) 2

3) 49

4) 63

Step-by-step explanation:

basically, you just have to figure out the difference between the input and the output. So input 4, output 28, I would guess that the proportion is 7, because 4 x 7 = 28. So for #1, do 14/7 to get 2. and so on. See the answer above.

Answer:im kinda confused can you explain what it means?

Step-by-step explanation:

Answer:

The slope for 7. is 1

Slope for 8. is  3

Step-by-step explanation:

7. if you graph the points, you will find a slope of 1/1 (1)

8. if you graph the points, you will find a slope of 1.5/0.5 (3)

Answer:

x= 6

Step-by-step explanation:

For (A) Mean: (24+13+17)/3 = 18

Median: 17 because it is the middle number

For (B) Mean: (14+32+20+x)/4=18    18*4 = 72    14+32+20= 66   72-66= 6

x= 6   6, 14, 20, 32      (14+20)/2 = 17

Answer:

x-3y+12 = 12-3y-2x+x+2x

3y+12 = x+3y+2x-3x+7+5

3x+y-12 = 4y+3y+3x-6y-10-2

x+3y+12 = 3x+2y-2x+y+12

Step-by-step explanation:

Answer:

Here ya go

Step-by-step explanation:

x-3y+12 = 12-3y-2x+x+2x

3y+12 = x+3y+2x-3x+7+5

3x+y-12 = 4y+3y+3x-6y-10-2

x+3y+12 = 3x+2y-2x+y+12

Answer:

Cube 2

Step-by-step explanation:

The order of operations are PEMDAS.

P = parenthesis

E = exponent

M = multiplication

D = division

A = addition

S = subtraction

Since we don't have any parenthesis, so the first thing we have to do is solve the exponent

Answer:

c

Step-by-step explanation:

The location where Jonathan should plot this value is at the one-third mark or one-third of the total distance on the number line. Option B

To plot the value of 33 1/3% on a number line, we need to locate the position that represents one-third of the total distance.

Given that one-third is equal to 33 1/3%, Jonathan should plot this value at the point that is one-third of the way from the starting point to the endpoint on the number line.

This indicates that the location where Jonathan should plot this value is at the one-third mark or one-third of the total distance on the number line. Option B

Answer: the common ratio would be -9

Answer:

18 m

Step-by-step explanation:

Given,

Volume of the cone = 3183.96 cubic meters

Radius of the cone = 13 m

Therefore, by the problem,

[tex] = > \frac{1}{3} \pi {r}^{2} h = 3183.96[/tex]

[tex] = > h = \frac{3183.96 \times 3}{3.14 \times 13 \times 13 \times 1 } [/tex]

=> h = 18 m (Ans)

A negative times a negative is a positive, so basically you just multiply 3x5

Answer: The answer is positive 15

Step-by-step explanation: 2 negatives make a positive so -3 x -5 would be 15

Answer:

=15j+15

Step-by-step explanation:

Answer:

Here are some expressions you could use!

15j + 15

or

5(2j + 3 + j)

or

25(10j + 18 + 5j)

or

4(5j + 8 + 4j)

or

10(4j + 6 + 2j)

All of these are right you can choose which one to use! 25(10j + 18 + 5j) is the easiest one to solve in my opinion.

Answer: -3x-5

Step-by-step explanation:

Answer:

-3x -5

Step-by-step explanation:

You would do -8x + 2 + 5x - 7. Then add 2 and 7 to get 5. After that you do -8x -5 + 5x. Then -8x - 5 +5x to get -3x - 5 because you do 8-5 to get 3.

Answer:

a= 4

Step-by-step explanation:

here's your solution

=> 4a - 4 = 8 + a

=> 4a - a = 8 + 4

=> 3a = 12

=> a= 12/3

=> a = 4
