Randal answers 96 out of 120 questions correctly on a science exam. What percent of the questions did Randal answer correctly

2 answers:

6 0

The fraction or division problem becomes the # right/the total number of problems=96/120=0.8 This is a DECIMAL, so to get a PERCENT you need to MULTIPLY by 100. 80% correct is the right answer.

You would divide the small number by the big to get a decimal from which u simply multiply by 109 to get a percentage so
96 divided by 120=0.8 and simply multiply by 100 to get a percentage which is also 80% that so now hope this helps :)

Here is you're answer:

In order to get you're answer you need to find the common denominator then add.

$\frac{1}{6} + \frac{3}{8}$
Find the common denominator:
$CD = 48$
$= \frac{26}{48}$
Simplify:
$\frac{26}{48} \div 2 = \frac{13}{24}$
$= \frac{13}{24}$

Therefore you're answer is option D "13/24."

Hope this helps!

Which of the following shows the numbers in the box below listed in increasing order?

Anarel [89]

9514 1404 393

Answer:

(A) -2, 3/7, 1/2, 1.2

Step-by-step explanation:

The numbers are in increasing order when they are listed left-to-right as they appear on the number line.

The only numbers that may give you trouble are 3/7 = 6/14 and 1/2 = 7/14.

The negative number is less than any positive number. 1.2 is greater than any fraction that is less than 1.

The correct ordering is found in choice A.

Find the area of the shaded region.

olasank [31]

Area of the big triangle (shaded area and small tris for below) is 36 * 51 divided by 2 (area of triangle is base * height over 2). this would give you 918.

area of the small triangle below is 51 * 11 divided by 2 (see above), which is 280.5.

shaded shape area is the big triangle shape minus the small triangle below, which is 918-270.5, which is 637.5 units.
