Answer:
C) 24
Step-by-step explanation:
we know that 18 students is 75% of the class and we need to know 100% of the class. to calculate this, divide the 18 students by 75% to work out what 1% of the students equals:
18 ÷ 75 = 0.24
0.24 students = 1% of the class. multiply this number by 100 to calculate 100% of the class:
0.24 x 100 = 24
∴ there are 24 students in Ms. Perron's class

The ratio of the height (h) of the streetlight to its distance to the end of Laura's shadow is the same as the ratio of Laura's height to her distance from the end of her shadow.
.. h/(12+9) = 5'4"/9
.. h = (21/9)*5'4" = 12 4/9 feet
.. h = 12 ft 5 1/3 inches
The streetlight is 12 ft 5 1/3 inches tall.
True. There are two ways to solve this; one, a shortcut , which is when you add each of them up and they are greater than each other (9+4= 13, which is greater than 11), or you could also use the Pythagorean theorem to solve the problem; the formula is
a squared + b squared= c squared
