Your Overall grade is calculated by adding 35% of your Minor grade to 65% *
max2010maxim [7]

Answer:

69%

Step-by-step explanation:

Overall grade = 0.35*minor grade + 0.65*major grade

major grade: 0.65*61 = 39.65

minor grade: 0.35*84 = 29.4

total: 39.65+29.4 = 69.05

Rounded = 69%

two high school students are hired to rake leaves. They will work a couple hours each afternoon until the job is completed. They
Schach [20]

Answer:

x = 14 days

Step-by-step explanation:

To answer the question, find a function that represents the payment mode of plan A and an equation that represents the mode of payment of plan B.

For Plan B the payment is constant every afternoon, $ 11.5 (or 1150 cents) so the equation to represent this form of payment is as follows:

A = 1150x (with units in cents)

This equation represents the line of a line of slope 1150, which passes through point (0,0). Where x is the number of days {1, 2, 3 ....}

In form of payment B, the amount of payment is doubled each day. And the first payment is 2 cents. Therefore this model is represented by an exponential base 2 equation of the form:

B = (2) ^ x

Where x represents the number of days, which is always greater than 0 {1, 2, 3, 4 ...}

To know in which day the salary will be approximately the same we equate both equations and we clear x.

A = B

1150x = (2) ^ x\\1150x- (2) ^ x = 0

It is a somewhat difficult equation to solve, so I recommend iterating to get a value where the function approaches 0 (when this difference is zero it means that the A and B salaries are the same).

Suppose

x = 13 days

1150(13) - (2) ^ {13} = 6758cents

It is not equal to 0.

Let's try with x = 15

1150(15) - (2) ^ {15} = -15518 cents

Then the value that makes the function zero is between x = 13 and x = 15

Let's try with x = 14

1150(14) - (2) ^ {14} = -284 cents = 2.84 $ difference. X = 14 is the whole number where functions A and B are closer together (the salary is approximately the same). Therefore the answer is

x = 14 days

-6(x + 3)+ 2x=7x-18-11x
Serggg [28]

Answer:

<em>X=</em><em>-</em><em>1</em><em>8</em><em>/</em><em>7</em>

Step-by-step explanation:

-6x+18+2x=-18x-18

-4x+18= -18x-18

-4x+18x=-18-18

14x=-36

x=-36/14

x=-18/7
