Serena spent $8.20 buying cupcake ingredients. At the school bake sale she charged $0.75 per cupcake. If she made a profit of $14.30, how many cupcakes did she sell?


What is the equation?
14.30 - 8.20 = 0.75c
8.20 + 0.75c = 14.30
0.75c - 8.20 = 14.30
14.30 - 0.75c = 8.20

20% of the students in Mrs. Sosa’s class like veggie pizza. If there are 50 students in the class, how many students like veggie pizza?

Answers

Answer:

10 students like veggie pizza

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

20% is equivalent to 0.2. If we do the math 50 x 0.2, we get 10.

Solving 50 x 0.2:

50 x 0.2 | Move the decimal right once to make a whole in 0.2, move the decimal left one (because we are doing multiplication) in 50.

5.0 x 02 | Remove any unnecessary 0s.

5 x 2 | Solve.

10 | Answer.

50 x 0.2 = 10

The diagonal of a TV is 42 inches. The base is 38 inches wide. How tall is the Tv? Round your answer to the nearest tenth. Put your answer in the box. EX: 10

Answers

Answer:20.6 inches

Step-by-step explanation:

The diagonal measure of a rectangular TV screen is 42 inches. The width of the screen is 36.6 inches.

The diagonal , width and height forms a right angle triangle

So we apply pythagorean theorem

Diagonal is the hypotenuse

LEt the height of the screen is 'h'

c^2= a^2 + b^2

42^2= 36.6^2 + h^2

Subtract 36.6^2 from both sides

h^2 = 424.44

Take square root on both sides

h=20.60194

Round to nearest tenth

Height of the screen = 20.6 inches

Answer:

1,600 inches

Step-by-step explanation:

You need to take the height of the tv and the base of the tv. So you need to take 42x38= 1,596. Now you need to round to the nearest tenth. So take 1,596 and the nearest tenth would be 1,600. Because 1,596 is closer to 1,596 then 1,590.

Answer:

27. C

28. D

Step-by-step explanation:

The average of all grades in his fencing class, including the upcoming one, (all grades summed up divided by the amount of grades) must be equal to 86 (percent), hence C is the right answer for 27.

Solving this equation gives:

[tex]\frac{75+88+62+100+x}{5} = 86\\325 + x = 86 \cdot 5\\x = 430 - 325 = 105[/tex]

So D is the right answer for 28.
