Jasmine has painted two of her bedroom walls. She wants to put decorative trim around the perimeter of the walls and around the door and window. The ceiling is 8 feet high. One wall is 18 feet in length, but it has a French door measuring 5 feet wide and 7 feet tall. The other wall is 15 feet in length and has a large window measuring 6 feet wide and 3 feet tall. She will not put trim at the base of the door.

Answers

Given the data below, the total length or amount of decorative trim can be calculated. It can be said that the total length of decorative trim is equal to the total perimeter of the two walls, the window, and the door, minus the base of the door.

Wall 1 = 2(8) + 2(18) = 52 ft.
Wall 2 = 2(8) + 2(15) = 46 ft.
Window = 2(3) + 2(6) = 18 ft.
Door = 2(7) + 5 = 19 ft.

Total length = 52+46+18+19 = 135 ft. of decorative trim

Cambridge has a job mowing lawns. He mowed 5 lawns last week and earned $82.50. The table shows his earnings for the week. Which coordinate pair represents the unit rate for this situation?A) (0, 0)
B) (1, 16.5)
C) (3, 49.5)
D) (5, 82.5)

Answers

Answer:

Option B.

Step-by-step explanation:

Consider the below table attached with this question.

It is given that Cambridge has a job mowing lawns. He mowed 5 lawns last week and earned $82.50.

We need to find the coordinate pair that represents the unit rate for this situation.

Unit rate represent the value of dependent variable when the value of independent variable is 1.

In the given situation, dependent variable is earnings and independent variable is number of lawns.

5 lawns = $82.50

Divide both sides by 5.

1 lawns = $16.5

So, the unit rate rate is $16.5 and the required coordinates are (1,16.5).

Therefore, the correct option is B.

i think so its B 82.50÷5=16.5

Don completes the square for the equation x^2 + 6x + 3 = 0. Which of the following equations reveals the vertex of the parabola?

Answers

x² + 6x + 3 = 0

y = x² + 6x + 3
y - 3 = x² + 6x

6x ⇒ 6x / 2x = 3 ⇒ 3² = 9

y - 3 + 9 = x² + 6x + 9
y + 6 = (x+3)²
y = (x+3)² - 6

vertex of the parabola is (x+3)²

y = (x+3)(x+3) - 6
y = x(x+3)+3(x+3) - 6
y = x² + 3x + 3x + 9 - 6
y = x² + 6x + 3
