Mr. Howard planted a new garden. The garden is 15 feet long and 4 feet wide. What is the perimeter of mr. Howard's garden?

MrRissso [65]

Answer: 38 feet

Step-by-step explanation:

Based on the dimensions of the garden, we can infer that it a rectangular garden because one side is longer than the other.

The perimeter of a rectangle is calculated as:

= (2 * length) + (2 * width)

= (2 * 15) + (2 * 4)

= 30 + 8

= 38 feet

<h2>SOLVING</h2>

$\Large\maltese\underline{\textsf{A. What is Asked}}$

Which ordered pairs make the equation $\bf{3x+2y=-7}$ true? Select all that apply. 3 options are given

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

We can tell which ordered pairs make equations true by plugging in the coordinates.

$\mathbb{ORDERED\;PAIR\;NUMBER\;ONE}$

$\bf{3(3)+2(-8)=-7}$ | simplify

$\bf{9-16=-7}$ |simplify

$\bf{-7\equiv-7}$ | this one checks

$\mathbb{ORDERED\;PAIR\;NUMBER\;TWO}$

$\bf{3(-2)+2(-1)=-7}$ | simplify

$\bf{-6-2=-7}$ | simplify

$\bf{-8\neq-7}$ | this one does not check

$\mathbb{ORDERED\;PAIR\;NUMBER\;THREE}$

$\bf{3(1)+2(-4)=-7}$ | simplify

$\bf{3-8=-7}$ | simplify

$\bf{-5\ne-7}$ | this one does not check

$\rule{300}{1.7}$

Step-by-step explanation:

Question

Lisa lit a candle with a height of 8 inches. When lit, this candle loses 10% of its original height every hour.
Please complete the following sentence by writing the number in the blank. Until the candle has been burning for at least _______ hours, the height of Jennifer's candle will be more than 7 inches.

Candle looses 10% of 8 inches, it equals:

8*0.1 = 0.8 inches an hour

Let x be required time, then:

8 - 0.8x > 7
0.8x < 8 - 7
0.8x < 1
x < 1/0.8
x < 1.25
or 1 hour 15 minutes
