What was the median number of items purchased? Show your work

Answer:

The ratio of copper, nickel and zinc required in the alloy = 12 : 5 : 3

12 → copper

5x → nickel

3 → zinc

The weight of the alloy = 5 kg

*12x + 5x + 3x = 512x+5x+3x=5*

Copper is 12*1/4 which equals 3kg

Nickel is 5*1/4 which equals 1.25kg

Zinc is 3*1/4 which equals .75kg

Have a great day! Hope this helps!

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:

-22

Step-by-step explanation:

it seems each point is increasing by 3. since the needed point is two behind -16 the result would be -22

(hopefully that'sright)

Answer:

50

Step-by-step explanation:

Step 1: Recognizing that we have an isosceles triangle

This is an isosceles triangle because it has two congruent sides(two sides with a length of 7). The angles across from the congruent sides are also congruent, so the angle without a label measures x∘

x, degrees:

Hint #22 / 4

Step 2: Writing an equation

The three angles in a triangle add up to 180 180  ∘

180, degrees. We can write this as an equation:

x + x + 80 = 180∘

+x  ∘

+80  ∘

=180  ∘

x, degrees, plus, x, degrees, plus, 80, degrees, equals, 180, degrees

Hint #33 / 4

Step 3: Solving for x

x+x+80

2x+80

2x+80−80

2x

2x

​

=180

=180        Simplify the left-hand side

=180−80        Subtract 80 from each side

=100

=

       Divide each side by 2

=50

Answer:

Number 9: A

Number 10: A

Step-by-step explanation:

Judging by the other answers for each questions, those make the most sense. Hope this helps :)

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:

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:

0.64 or 16/25

Step-by-step explanation:

multiply

4/5 times 4/5

that would be 0.64

or  16/25

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

Answer:

  600 cm³

Step-by-step explanation:

The volume of a prism is the product of the area of the base and the length of the prism (distance between parallel bases). It is given by the formula:

  V = Bh

__

This triangular prism has a base area that is ...

  A = 1/2bh . . . . . formula for area of a triangle with base b and height h

  A = 1/2(6 cm)(8 cm) = 24 cm²

Then the prism volume is ...

  V = Bh

  V = (24 cm²)(25 cm) = 600 cm³

The volume of the block is 600 cubic centimeters.

Answer:

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

Answer:

the volume of this is 36cm

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:

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
