Mike is building storage boxes. Each box will have a length of 5 feet, a width of 412 feet, and a height of 312 feet. A pint of

alex41 [277]

The pints of paint that Mike needs to buy in order to paint 4 boxes is 9 pints.

How many pints is needed?

The first step is determine the total surface area of a box.

Total surface area of a cuboid = 2 (lw + wh + lh)

where:
l = length
w = width
h = height

2 x[ (5 x 9/2) + (9/2 x 7/2) + (5 x 7/2) ]
2 x ( 45/2 + 63/4 + 35/2) = 111.5ft

The second step is to determine the total surface area of 4 boxes:

111.5 x 4 = 446

Now, divide 446 by 50

446 / 50 = 9 pints

Find the value.<br> 9x+6 when x=-2/3

OLEGan [10]

Answer:

Step-by-step explanation:

Given,

$- \frac{2}{3}$

Now, let's find the value of 9x + 6

$9x + 6$

plug the value of X

$= 9 \times (- \frac{2}{3} ) + 6$

Multiplying a positive and negative equals a negative

$( + ) \times ( - ) = ( - )$

$= - 9 \times \frac{2}{3} + 6$

Reduce the number with Greatest Common Factor 3

$= - 3 \times 2 + 6$

Multiply the numbers

$= - 6 + 6$

The sum of two opposites equals 0

$= 0$

Hope this helps..

best regards!!

City A grows by 5% every year. In 2021, it has a population of 145,201. What will the population be in 2037?

Diano4ka-milaya [45]

Answer:

About 316,955 people

Step-by-step explanation:

The population of this city can be modeled with the formula $P=I\cdot(1.05^t)$ , where P represents the current population, I represents the initial population, and t represents the amount of time in years since the start of the model. Plugging in 145,201 for I and (2037-2021)=16 for t, we get:
