how many multiple- choices questions did tanika get correct

Answers

Answer 1
Answer: this is a ratio based problem.
knowing that there are 20 mc questions and she got 9/10 of them right, we can solve the problem by getting the equivalent fraction that has the same denominator as the total number of mc questions ( in this case,20)

multiplying 9/10 by 2/2, we get 18/20 and that's the answer
Answer 2
Answer: She got 19 answers correct.

The base of a rectangular box has a width of 3 inches and a length of 4 inches. The box is 12 inches inches tall. a) Draw a picture of the box below b) How far is it from one of the box's top corners to the opposite corner of the base of the box?

Answers

Answer:

a) attached the figure.

b) diagonal (d) = 13 inches

Step-by-step explanation:

The given figure is a rectangular box in which the length = 4 inches, width = 3 inches, and height = 12 inches.

a) Draw the figure and attached.

b) To find the diagonal from one of the box's top corners to the opposite corner of the base of the box, we have formula.

Diagonal length from top corner to corner of the base (d) = √(l^2 + w^2 + h^2)

We know that l = 4 , w = 3 and h = 12

Now plug in these values in the above formula, and find the diagonal.

d = √(4^2 + 3^2 + 12^2)

d = √(16 + 9 + 144) = √(169)

d = 13 inches.
it would be 144 inches
