Answer:

Option B. 12\ ft

Step-by-step explanation:

we know that

The area of a square is equal to

A=x^{2}

where

x is the length side of the square

In this problem we have

A=144\ ft^{2}

substitute and solve for x

144=x^{2}

suqre root both sides

x=12\ ft

Solve this equation. Enter your answer in the box.<br> 75 – 3.5y – 4y = 4y + 6
Wewaii [24]

y=6

Step-by-step explanation:

75 - 3.5y - 4y = 4y + 6

Collect like terms and simplify

- 3.5y + 4y - 4y = 6 - 75 \\  - 11.5y =  - 69

Divide both sides of the equation by-3.5

\frac{ - 11.5y}{ -11.5}  =  \frac{ - 69}{ - 11.5}

Simplify

y = 6

Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%. Its current value is $2,000. The equ
77julia77 [94]

Answer:

Step-by-step explanation:

Use the equation 2,000 = 16,000(1-r)^t to solve for t;

2000 = 16000(1-0.35)^t

Divide both sides by 16000

2000/16000 = 0.65^t

0.125 =0.65^t

Introduce logarithm on both sides;

<em>ln</em> 0.125 = t <em>ln</em> 0.65

Divide both sides by <em>ln</em> 0.65;

(<em>ln</em> 0.125) / (<em>ln</em> 0.65) = t

-2.07944/ -0.4308 = t

4.827 = t

t= 5 (as a whole number)

Therefore, the car is about 5 years old.

Sergeeva-Olga [200]

Number of toothpicks required per student = At least 9

Total number of students = 30

Number of toothpicks required for the entire class = At least 9 × 30 = At least 270

Number of toothpicks in the bag in the class storage room = 50

Additional number of toothpicks required to be bought to make sure there are enough toothpicks = 270 - 50 = 220

Hence, she needs to buy 220 toothpicks.
