Aurora Corporation operated without insurance coverage for the first month of 2015. Then, on February 1, 2015, the company paid
vitfil [10]

Answer:

$2200

Step-by-step explanation:

$4800 premium for 2 years means for 2* 12 = 24 months, thus each month, the insurance expense is:

4800/24 = 200 dollars

Since they haven't used insurance in January, they will use insurance expense for the rest of the 12 - 1 = 11 months, thus the expense would be:

200 * 100 = $2200

I need help please please I appreciate it! ):

Answer:

!. Scale factor = 5

2. Scale factor = \frac{1}{5}

Step-by-step explanation:

scale = \frac{length in drawing}{actual length}

1. To increase the numbers, let the scale factor be \frac{5}{1} = 5. So that;

0.05 x 5 = 0.25

\frac{1}{2} x 5 = 0.5 x 5 = 2.50

7 x 5 = 35.00

13 x 5 = 65.00

25 x 5 = 125.00

102 x 5 = 510.00

2. To decrease the numbers, let the scale factor be \frac{1}{5}. So that;

0.05 x \frac{1}{5} = 0.01

\frac{1}{2} x \frac{1}{5} = 0.5 x \frac{1}{5} = 0.10

7 x \frac{1}{5} = 1.40

13 x \frac{1}{5} = 2.60

25 x \frac{1}{5} = 5.00

102 x \frac{1}{5} = 20.40

Two-thirds a number plus 4 is 7
ICE Princess25 [194]

The equation (form) is: \frac{2}{3}x + 4 = 7

The solution of the equation is: x = \frac{9}{2}


Explanation:

First, let's call the number we are going to solve for "x".

Then two thirds of this number can be written as:

\frac{2}{3}x

Then "plus 4" means add 4 we get:

\frac{2}{3}x + 4

"is 7" means that the above expression is equal to 7 (as follows):

\frac{2}{3}x + 4 = 7

The solution of the above equation is:

\frac{2}{3}x + 4 = 7 \\ \frac{2}{3}x = 3 \\ x =  \frac{9}{2}

Write the slope intercept form of the equation given the point (-2,4) and a slope of 3
Hitman42 [59]

Given the points:

(x, y) ==> (-2, 4)

slope, m = 3

To write the slope intercept form, use the form below:

y = mx + b

Where m = slope and b = y-intercept.

Now, substitute -2 for x, 4 for y, and m for 3 in the equation above to solve for b.

We have:

y = mx + b

4 = 3(-2) + b

4 = -6 + b

Add 6 to both sides:

4 + 6 = -6 + 6 + b

10 = b

b = 10

Therefore, the slope intercept form of the equation is:

y = 3x + 10

ANSWER:

y = 3x + 10
