Answer and Step-by-step explanation:

$First, ~multiply~base~and~height.~In~our~case~the~base~is~30~inches~and$ $the~height~is~12~inches.$ $Then,~we 'll~take~16~inches~and~multiply~it~with~12~inches$

So, it'll be :

$30~inches$ × $12~inches$ $=360~inches$

$16~inches$ × $12~inches=192~inches$

$Now,~that~we've~got~ 360 ~and~ 192~ as~ our~ answers ~we ~add~ them ~up..$

Like this :

 $360+192=552$ 

 $And,~that's~our~final~answer!-522~in^2$

A yearbook printer charges based on the number of pages printed. Here is a table that shows the cost of some recent yearbooks:

asambeis [7]

y = 0.012x + 0.65

Number of pages 50.00 100.00 150.00 200.00 
Cost 1.25 1.85 2.45 3.05

x = number of pages
y = cost

intervals of x = 50 pages
intervals of y = 0.60
0.60 / 50 = 0.012

y = 0.012x + 0.65

 x 0.012*x y 
 0.012 50 0.60 0.65 1.25
0.012 100 1.20 0.65 1.85
 0.012 150 1.80 0.65 2.45
 0.012 200 2.40 0.65 3.05

Find four consecutive integers with the sum of -142

Akimi4 [234]

n, n + 1, n + 2, n + 3 - four consecutive integers

-142 - the sum

The equation:

n + (n + 1) + (n + 2) + (n + 3) = -142

n + n + 1 + n + 2 + n + 3 = -142

4n + 6 = -142 |subtract 6 from both sides

4n = -148 |divide both sides by 4

n = -37

n + 1 = -37 + 1 = -36

n + 2 = -37 + 2 = -35

n + 3 = -37 + 3 = -34

Answer: -37, -36, -35, -34.

Answer:

See below

Step-by-step explanation:

Question 7

The rate of change in Health Club A is 12 as given in slope-intercept form
The rate of change in Health Club B is 21 as given by an increase of $21 per month
The rate of change in Health Club C is 15 as given by (70-40)/(3-1)=15
The rate of change in Health Club D is 20 as given by "$20 each month for x months"
Therefore, Health Club B has the greatest rate of change of $21 per month

Question 8:

The initial value of Health Club A is 60 as given in slope-intercept form
The initial value of Health Club B is 0 as given by $0 for 0 months
The initial value of Health Club C is 25 as given by y=mx+b --> 40=15(1)+b --> b=25
The initial value of Health Club D is 20 as given by "A customer pays a one-time fee of $20"
Therefore, Health Club A has the greatest initial value (or y-intercept) of $60
