Answer:

1/4(πr²)

Step-by-step explanation:

Answer: 189.1 astronomical units

Step-by-step explanation:

The formula for the circumference of a circle is the C=dπ (circumference = diameter times pi)

the diameter is just the radius times 2

30.1 · 2 = 60.2

now multiply that by pi to find the circumference

60.2 · π = 189.1 astronomical units

Answer:

6 1/6 feet

Step-by-step explanation:

1. Add the fractions

2. Multiply the sum of the fractions by 2

6 1/6 feet

Lets Go deeper.

First add the whole numbers.
2+2=4
Next lets add the fractions 1/3 +1/3 = 2/3
When a fraction has the same denominator there is no need for finding the GCF
So far we have two sides done let us do the other side.
3/4+3/4=3/2

Next lets combine what we got

Answer:

1. MAD= 1.75

2. 2.204

3. 6.16

4. 13

5. 2.33

6. 4.11

7. 1.33

8. 2.33

Answer:

Box plot graphs tell you about your outliers and what their values are.

Answer:

I only know the first 1 sorry but here is the answer y=-3/4+2

Step-by-step explanation:

3x+4y=8

-3x      -3x subtract -3x to get on the right side

4y=-3x+8

/4     /4    /4 divide by 4 on both sides

y=-3/4x+2 since 4 can't go into 3 you leave as a fraction -3/4x

UPDATE: I found the answer to number 4

The answer is y=-11/7x+8

-11x-7y=-56

+11x       +11x Add 11x

-7y=11x-56

/-7   /-7  /-7 Divide by -7 on both sides

y=-11/7x+8 Since -7 can't go into 11 you leave as a fraction -11/7x

ANOTHER UPDATE: I found the answer to number 7

-14x+y=7

+14x     +14x Add 14x to both sides

y=14x+7 Since y doesn't have a number your answer is as shown

Answer:

5.1 pints

Step-by-step explanation:

Theres 2 ways

First way:

We can do 2/5 of 8.5 which is 3.4. Then, we can subtract 3.4 from 8.5 and get 5.1 pints.

Second way:

We can simply do 3/5 of 8.5 because the remaining 3/5 of the paint is blue. 3/5 of 8.5 is 5.1 pints

Answer:

they decreases

Step-by-step explanation:

with the 25 taken away the mean goes from 10 to 8.3

big math

Answer:

1)

16=25%

x=100%

25x=1600

x=64

2)

6300/1260 * 100 = 20

100 - 20 = 80%

3)

Total: 40

Set desingers: 16

16/40 =  40%

4)

500*22%=110

500-110=390

Hope this helped you! I would appreciate a Brainliest, if this answer helped you out!

1.) 64

2.) 80%

3.)40%

4.)390

Step-by-step explanation:

Answer:

Answer = 93.6

Step-by-step explanation:

frist multipy 9 x 13 to get 117 than divided it by 2 = 58.5, than times it by 3 since there is three sides.

(58.5 x 3 is 175.5)      

Than for the base multipy 7.8 x 9 = 70.2, but since its a tri, divided it by 2 = 35.1.

Add 58.5 and 35.1 to get 93.6

Answer:

38% or .38

Step-by-step explanation:

I think

Answer:

The only answer that would possibly would make sense would be E.

Step-by-step explanation:

First, let's find out how many ounces of berries it takes to make 8 berry pies. If you got 224, that's correct. If you don't understand, just look at the chart and see how many Blueberries, Raspberries, and Strawberries, in the weight of ounces, which is 8+8+12=28. Then, multiply 28x8=224.

The second step to finding the problem is converting 224 ounces to pounds, the quick answer being 14 pounds.

(You will need to reread the question to look at this step). If you read the question properly, you will see that Jude picked 2 pounds of raspberries.    Reading information is crucial to answering any question. If you're going to fully answer the question, you need to convert 2 pounds to ounces, so you can add all the ounces, and then convert the total ounces to pounds. I would suggest reread the question now, if you need to. If you saw that Karen picked 48 ounces of Blueberries. (that was just extra info if you needed it), but now we need to convert 6 pounds to ounces, that being 96 ounces. Now, add the 3 total ounces for each berry, which is 32+48+96, which is 176.

Now, we need to convert 176 ounces to pounds, which is 11 pounds.

(Again, the total amount of ounces of berries needed to make 8 berry pies is 14 pounds). Now, if you look at the answer, now it makes immediate sense, ( the answer E). If the total pounds of berries that they picked is 11, and the total amount needed is 14 pounds, the total amount they picked is 3 pounds off, and what answer E says is 1 more pound of blueberries and 2 more pounds of raspberries, 1+2=3, it just clicks in your brain immediatly.

Answer:

[tex]8y^2-10y+3[/tex]

Step-by-step explanation:

Step 1:  Distribute

[tex](2y - 1)(4y - 3)[/tex]

[tex](2y * 4y) + (2y * -3) + (-1 * 4y) + (-1 * -3)[/tex]

[tex]8y^2 - 6y - 4y + 3[/tex]

Step 2:  Combine like terms

[tex]8y^2 +( - 6y - 4y )+ 3[/tex]

[tex]8y^2+(-10y)+3[/tex]

[tex]8y^2-10y+3[/tex]

Answer:  [tex]8y^2-10y+3[/tex]

Step-by-step explanation:

the sisters used a total of 5 cards out of 12 cards

If it's likely to happen, but it's not a certainty, then it has a high chance of happening. Pick P(D).

Answer:

2/8 probability

Step-by-step explanation:

Answer:

total number of outcomes possible = 8 { from table }

Number of outcomes with exactly one tail = 3

probability of getting exactly one tail = 3/8

I hope it's understandable.
