Rosa's test scores are 78, 92, 88, and 89. What must she score on her next test to have an average of 90? A) 95 B) 97 C) 99 D) 1

Morgarella [4.7K]

Answer: D

Step-by-step explanation:

Let x represent the score on her next test

$\frac{78 + 92 + 88 + 89 + x}{5} = 90$

$(5)\frac{78 + 92 + 88 + 89 + x}{5} = (5)90$

78 + 92 + 88 + 89 + x = 5(90)

347 + x = 450

-347 -347

x = 103

I need help with number 33!!!

Area of Big Rectangle Area of Small Rectangle

A = L x w A = L x w

= (25 + 2w)(10 + 2w) = 25 x 10

= 250 + 50w + 20w + 4w² = 250

Big - Small

74 = 250 + 70w + 4w² - 250

74 = 4w² + 70w

0 = 4w² + 70w - 74

= 2(2w² + 35w - 37)

= 2[2w² -2w | +37w - 37]

= 2[2w(w - 1) | +1(w - 1)]

= 2(2w + 1)(w - 1)

0 = 2 0 = 2w + 1 0 = w - 1

FALSE so disregard w = -1/2 w = 1

NEGATIVE so disregard

PLEASE HELP ME!!! THE RIGHT ANSWER WILL GET THE BRAINIEST!

Answer:

$\sf D) \quad s=8 \frac{1}{4}t$

Step-by-step explanation:

t = time (in hours) → this is the independent variable
s = total area cleaned (in square feet) → this is the dependent variable (as the number of square feet cleaned depends on the number of hours worked)

Therefore, if the rate of cleaning is 8 1/4 square feet per hour, the relationship between s and t is:

$\sf s=8 \frac{1}{4}t$
