Answer:

Number of quarts=16

Money earned=$32

Step-by-step explanation:

Given

  • 4 Gallons of lemonade is prepared
  • They charge $2 for a quart

1 Gallon= 4 Quarts

Therefore Number of quarts

= \text{number of gallons} \times 4\\= 4 \times 4\\=16

Therefore Number of quarts of lemonade prepared by them = 16 quarts

As they charge $2 for each quart

⇒

Total money made if they sell it all

=\text{number of quarts} \times 2\\= 16 \times 2\\=32

Therefore, if they are to sell all the lemonade that they prepared

They would earn=$32

If a || b, m∠2 = 63°, and m∠9 = 105°, find the measure of each missing angle.
Ne4ueva [31]

Given that a || b, m∠2 = 63° and m∠9 = 105°.

Now, all the angles are as follows:

m∠5= m∠2 = 63° [vertically opposite angle]

m∠7= m∠9=105° [vertically opposite angle]

m∠8= 180°-m∠9=180°-105°=75° [Supplementry angles, m∠8+m∠9=180°]

m∠10= m∠8= 180° [vertically opposite angle]

m∠6= m∠8=75° [ Alternate angles]

m∠3= m∠6=75° [vertically opposite angle]

m∠1= 180°-(m∠2+m∠3)=180°-(63°+75°)=42° [as m∠1+m∠2+m∠3=180°]

m∠4= m∠1=42° [vertically opposite angle]

m∠11=m∠4=42° [ Alternate angles]

m∠13= m∠11=42° [vertically opposite angle]

m∠12= 180°-m∠11=180°-42°=138° [as m∠8+m∠9=180°]

m∠14 = m∠12=138° [vertically opposite angle]

Rita makes and sells necklaces. The materials to make each necklace cost $2.75. Last week she made 8 necklaces and wants to make
Tresset [83]

Answer:

The error she made was that she was adding x and 2.75. She should subtract 2.75 from x.

Another mistake that she made was that she sold each for $7 assuming that she would make a profit of 78, but she should see each necklace for $12.5 so that she could make a profit of $78.

Step-by-step explanation:

The error she made was that she was adding x and 2.75.

She should write the equation as 8 (x - 2.75) = 78; as she spends $2.75 to make a necklace.

By using the correct equation: 8 (x - 2.75) = 78

=> 8x - 22 = 78

=> 8x = 78 + 22

=> 8x = 100

=> x = 100/8

=> x = 12.5

Another mistake that she made was that she sold each for $7 assuming that she would make a profit of 78, but she should see each necklace for $12.5 so that she could make a profit of $78.

Hope this helps you.

1. a. A cube’s volume is 512 cubic units. What is the length of its edge?
Vanyuwa [196]

Answer:

a) The length of its edge is 8 units.

b) The volume of the sphere is approximately 268.083 cubic units.

c) The fraction of the cube that is taken up by the sphere is 0.524, whose equivalent in percentage form is 52.4 %.

Step-by-step explanation:

a) The volume of a cube (V_{c}), measured in cubic units, is defined by the following expression:

V_{c} = L^{3} (1)

Where L is the side length of the cube, measured in units.

If we know that V_{c} = 512\,u^{3}, then the length of its edge is:

L = \sqrt[3]{V_{c}}

L = 8\,u

The length of its edge is 8 units.

b) The volume of a sphere (V_{s}), measured in cubic units, that fits snugly inside this cube is defined by:

V_{s} = \frac{\pi}{6}\cdot L^{3} (2)

If we know that L = 8\,u, then the volume of the sphere is:

V_{s} \approx 268.083\,u^{3}

The volume of the sphere is approximately 268.083 cubic units.

c) The fraction of the cube taken by the sphere is the ratio of the volume of the sphere to the volume of the cube. That is to say:

r = \frac{V_{s}}{V_{c}}

If we know that V_{c} = 512\,u^{3} and V_{s} \approx 268.083\,u^{3}, then the fraction of the cube that is taken up by the sphere is:

r = 0.524

The result in percentage form is calculated by multiplying the result above by 100.

\% r = 52.4\,\%

The fraction of the cube that is taken up by the sphere is 0.524, whose equivalent in percentage form is 52.4 %.

I need help ASAP pleaseee helppp I’ll maker brainliest:((<br> It’s number 2
siniylev [52]

Answer:

J

Step-by-step explanation:

When finding the distance between the two points you use the formula

d(distance)= square root of ( x2-x1)^2+(y2-y1)^2. So since you have the two points you just plug them into the formula to get

square root of (5-(-3))^2+(2-(-5))^2 and if you put that in a calculator you get 10.63014581. Then you just round to the nearest tenth and get the final answer of 10.6 (J)
