A student missed 16 problems on test and got a grade of 66% how many problems were on the test

Mathematics
1 answer:
seraphim [82]3 years ago
7 0

Those 16 problems cost him 34%

One problem is worth 34/16 = 2.0625


So each question is worth about 2 point.

2*x = 66 Divide by 2

x = 66 /2 = 33 questions that he got right.


The total number of questions is 33 + 16 = 49


Does the rounding really matter?

2.0625 x = 66

x = 66/2.0625

x = 32 yes it matters.


Total number of questions = 32 + 16 = 48 <<<< answer.

ayme built a box in the shape of a rectangular prism with the dimensions shown. What is the volume of the box, in cubic inches?
Snezhnost [94]

Answer:

64(in)^{3}

Step-by-step explanation:

The volume of a box is equal to the length l times the width w times the height h.

(lenght) \times (width) \times (height)

Substitute the values of the length l=8, the width w=2, and the height h=4 into the formula.

8 \times 2 \times 4

Multiply 8 by 2.

16 \times 4

Multiply 16 by 4.

64 {in}^{3}

Hence, the volume of the rectangle prism is 64(in)³.
