A baker makes a circular cake that has a radius of 7 inches. If
the baker wants to cover the top of the cake with frosting, how
much frosting should the baker use?

Answer:

Dimensions : L = 12 inches, Width = 2 inches

Step-by-step explanation:

Let width be w

Let length be w + 10

Area = length x width

24 = w x (w + 10)

[tex]24 = w^2 + 10w\\\\w^2 + 10w - 24 = 0\\\\w^2 +12w -2w -24 = 0\\\\w(w+12) -2(w+12) = 0\\(w-2)(w+12)=0 \\w = 2 , -12[/tex]

Since width is a side of a rectangle , it cannot be negative. so w = 2 inches .

Therefore , length = w + 10 = 12inches

Answer:

Mr. peter puts 24 students into groups of 8. How many groups are there?

Step-by-step explanation:

Whenever the word "groups" is used, it typically means to divide. Because we see the word "groups", it would be reasonable to assume that you will be dividing something.

Step-by-step explanation:

To solve exponential equations with same base, use the property of equality of exponential functions . If b is a positive number other than 1 , then bx=by if and only if x=y . In other words, if the bases are the same, then the exponents must be equal.

Answer:

Step-by-step explanation:

volume of pyramid with square base=a^2(h/3)

84=a^2*7/3

84*3/7=a^2

252/7=a^2

36=a^2

[tex]\sqrt{36[/tex]=a

6=a

therefore length=6

Answer:

$16,000

Step-by-step explanation:

This is because 5 is the thousand place and the hundredth place is more than 5 so, it rounds up (to 16000)

Answer:

16,000

Step-by-step explanation:

15,827

8 is greater than 4 so you round up

5 turns to 6 and everything to the right turns to 0

So the answer is 16,000

Answer:

It is a  sampling distribution of the sample proportion for which n = 150 and p = 0.58

Step-by-step explanation:

Given -

Probability of tails of a weighted coin = 0.58

Number of tail is noted each 25 times

Repetition of procedure = 150 times

mean =  p = 0.58

SD = Sqrt {p(1-p)/n}

Substituting the given values, we get -

SD = Sqrt {0.58(1 – 0.58)/150}

=  0.04029

It is a  sampling distribution of the sample proportion for which n = 150 and p = 0.58

Answer:

The options are not given so these are the options:

- A binomial distribution with n = 25 and p = 0.58

- A binomial distribution with n = 2 and p = 0.58

- A sampling distribution of the sample proportion with n = 25 and p = 0.58  

- A sampling distribution of the sample proportion with n = 150 and p = 0.58

- There is not enough information to determine the distribution.

Step-by-step explanation:

The answer is - A binomial distribution with n = 25 and p = 0.58.

I got it right on my test.

Answer:

y = 4x + 4

Step-by-step explanation:

2 points:

(-1, 0) and (0, 4)

Slope:

m=(y2-y1)/(x2-x1)

m=(4-0)/(0+1)

m= 4/1

m= 4

Slope-intercept:

y - y1 = m(x - x1)

y - 0 = 4(x + 1)

y = 4x + 4

Answer:

B and D

7/12 cups

Step-by-step explanation:

2 1/3 + 2 1/4 = cups of flour needed

4 = cups of flour had

2 1/3 + 2 1/4

To have the same denominator, we take the lcm

2 + 2 + (4/12 + 3/12) =

2 4/12 + 2 3/12 - 4

Or

2 + 2 + (3 + 4) / 12 - 4

2 + 2 + (3 + 4) / 12 - 4 = 4 7/12 - 4

4 7/12 - 4 = 7/12 cups of flour needed

Answer:

A. Yes

Step-by-step explanation:

I calculated it logically

Yes the given figure with triangular tessellates the plane.

All triangles tessellate.

The picture works because all three corners (A, B, and C) of the triangle come together to make a 180° angle - a straight line.

This property of triangles will be the foundation of our study of polygon tessellations, so we state it here: The sum of angles of any triangle is 180°.

Yes, the given figure tessellates the plane.

Hence, Yes the given figure tessellates the plane.

Answer:

Step-by-step explanation:

A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.

Total = 18 marbles.

Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.

Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.

Answer:

Step-by-step explanation:

1.  (a) 24 X 3/4= 18 multiplication

you have to multiply to get a smaller answer since you are using a fraction.

2. (a) 24 / (-3/4)= -32 division

you have to divide to get a bigger number than started since you are using a fraction

3. (A) 12-15= -3 subtraction

when you subtract a bigger number than the first number you end up normally with a negative number

4. (a) 12 -(-15) subtraction

when you subtract with a negative number you distribute so the two negatives cancel out and it become an addition sign. (if you look at it the two negatives and the parenthesis looks like an addition sign (+)

5. (A) -18 / (-3/4) =24 division

when you divide two negative values you will always get a positive answer. And again dividing a fraction will get you a bigger answer.

Answer:

Positive number: Elevation of a mountain above sea level, growth of a plant, money saved. Negative number: Temperature colder than 0.

Step-by-step explanation:

Elevation of a mountain that is above sea level is positive since it isn't below sea level, which would be negative, you are increasing as you go up. Growth of a plant is positive since it isn't growing shorter. Money saved since you aren't spending it. Temperature colder than 0 because that is when the negative numbers start to occur.
