Answer:

B. 60

Step-by-step explanation:

Start by estimating 10% = 40

Then do 1/2 if that = 20

add them to get 60 cars

or 15 for every 100 15x4=60

Answer:

B 60

Step-by-step explanation:

Finding the exact percentage of 395 gets you to 59.25. Rounding it gets you to 60 so that would be your estimate.

To find the percentage of something, you have to take the percentage and move the decimal 2 spots to the left ( %15 = 0.15 )

You then just multiply, ignoring the decimal to get 5925

After that, you have to place the decimal. There's 2 numbers to the right of the decimal so you move the decimal 2 places to the right in your final answer to get 59.25

taurus [48]

Answer:

The answer to your question is the chocolates are slightly lighter than the weight stated on the label.

Step-by-step explanation:

Data

The label says 0.384 pounds

Actual mass = 0.3798 pounds

Process

To solve this problem the only thing we must do is substrate the actual weight of chocolates to the weight of chocolates stated on the label.

If the result is positive, then the chocolates are lighter

If the result is negative, then the chocolates are heavier

0.384 pounds - 0.3798 pounds = 0.0042

The measure of one angle of an octagon is two times smaller that of the other seven angles. What is the measure of each angle?

Anestetic [448]

Answer:

7 of the angles measure 144 degrees each and one angle measures 72 degrees

Step-by-step explanation:

Let

x -----> represent the measures of the seven same-size angles,

x/2 ----> represent the measure of the one that is "two times smaller."

we know that

The sum of internal angles of a polygon can be calculated as:

$S=180^o(n-2)$

where

n is the number of sides of the polygon

In this case

n=8 (octagon)

substitute

$S=180^o(8-2)=1,080^o$

The linear equation that represent this problem is

$\frac{x}{2}+7x=1,080$

solve for x

$\frac{15x}{2}=1,080\\\\15x=2,160\\\\x=144^o$

$\frac{x}{2}=72^o$

therefore

7 of the angles measure 144 degrees each and one angle measures 72 degrees

Simplify and write answer in standard form.

mamaluj [8]

Answer:

$x^3+8x^2+2x+1$

Step-by-step explanation:

Combine like terms (terms with the same exponent).

$x^3+(3x^2+5x^2)+(x+x)+1=x^3+8x^2+2x+1$

"Standard form" means to list terms so the exponents go from high to low (descending order).
