Imagine you have a job where you earn $700 each week after taxes. Your monthly living expenses include $725 for rent, $125 for u
Softa [21]

The monthly income is $844.

Given:

  • Weekly earning after taxes is $700
  • Monthly rent is $725
  • Monthly expense for utilities is $125
  • Monthly expense for cable/internet is $120
  • Monthly expense for cellphone is $35
  • Monthly expense for bus fare is $48
  • Minimum monthly payment of credit card debt is $78
  • Monthly expense for groceries is $600
  • Monthly expense for dining out and entertainment is $225

To find: The monthly income

The monthly income refers to the amount of money left over each month after paying all expenses.

Evaluating, we have,

The total monthly expense = $(725 + 125 + 120 + 35 + 48 + 78 + 600 + 225)

That is, the total monthly expense is $1956.

It is given that weekly earning after taxes is $700. Since a month contains 4 weeks, we can say that monthly earning after taxes is $(700 \times 4), that is, $2800.

Then, monthly income is given by the difference between the monthly earnings and the monthly expenses. So, monthly income is $(2800-1956), that is, $844.

The monthly income is $844.

Which shows the pre-image of triangle X’Y’Z’ before the figure is rotated 90° about the origin
Xelga [282]

Answer:

From the figure shown the coordinates of W'X'Y'Z' are W'(2, 3), X'(6, 3), Y'(6, 4) and Z'(3, 5)

The coordinates of the pre-image that yeilded W'X'Y'Z' according to the rule (-x, -y) can be obtained by changing the signs of the coordinates of W'X'Y'Z'.

Thus, the coordinates of the pre-image that yeilded W'X'Y'Z' are W(-2, -3), X(-6, -3), Y(-6, -4) and Z(-3, -5).

Therefore, the correct graph is graph c.

In a triangle, the midline joining the midpoints of two sides is parallel to the third side and half as long

2(5x+2) = 3x + 32
10x + 4 = 3x + 32
10x - 3x = 32 - 4
7x = 28
x = 28/7
x = 4

The length of the midsegment = 5x+2 = 5·4 + 2 = 22
