Answer:

Area = 245 ft

(Width

Step-by-step explanation:

l = 5w

Where l is length and w is width.

We also know that the perimeter is 84 ft, so:

2l + 2w = 84

Now we can plug in 5w for l since we found the equality earlier:

2(5w) + 2w = 84

and then solve for w:

10w + 2w = 84

12w = 84

w = 7

so

l = 5 × 7

l = 35

The length is 35 and width is 7 so

the area of the rectangle is

7  \times  35 = 245ft

On the number line below, Point B lies somewhere between Points A and C. If AB = \frac{1}{3} AC. Find BC. a 16 b 0 c 8 d 24
ollegr [7]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the number line is not attached.

<em>However, the following will guide you through</em>

Given

AB = \frac{1}{3}AC

Required

Determine BC

First, we need to get the fraction of BC using the following

AB + BC = AC

Substitute \frac{1}{3}AC for AB

\frac{1}{3}AC + BC = AC

Make BC the subject of formula

BC = AC - \frac{1}{3}AC

Take LCM

BC =  \frac{3AC - AC}{3}

BC =  \frac{2AC}{3}

BC =  \frac{2}{3}AC

This implies that you multiply the length of AC by 2/3 to get BC

<em>Take for instance, AC = 24</em>

<em>BC will be:</em>

<em />BC = \frac{2}{3} * 24<em />

<em />BC = \frac{48}{3}<em />

<em />BC = 16<em />

<em />

<em>Or if AC = 12</em>

<em>BC will be:</em>

<em />BC = \frac{2}{3} * 12<em />

<em />BC = \frac{24}{3}<em />

<em />BC = 8<em />

<em />

<em>Or if AC = 36</em>

<em>BC will be:</em>

<em />BC = \frac{2}{3} *36<em />

<em />BC = \frac{72}{3}<em />

<em />BC = 24<em />

<em />

What is real numbers
Salsk061 [2.6K]

Answer:In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line. The adjective real in this context was introduced in the 17th century by René Descartes, who distinguished between real and imaginary roots of polynomials

I NEED YOUR HELP PLEASE GRADES ARE DUE TODAY AND I DONT KNOW HOW TO DO THIS.​
lawyer [7]

Answer:

#1 c. -1

#2 b. 1 is less than or equal to x which is less than or equal to three

#3 a. 37.5 is less than or equal to y which is less than or equal to 87.5

#4 b. 3

#5 b. (2, 3, 4, 5, 6)

#6 d. (45, 55, 65, 75, 85)

Step-by-step explanation:

Domain is the x value and y is the range. For #1 the answer is c because you can't go golfing for -1 hours. For #2, the answer is b because they are all the acceptable values for the domain which is represented by x and x is the time spent at the golfing bay. The answer would not be c because you could go to the bay for 2.75 hours it doesn't have to be just 1, 2, 3.  For #3 the concept is similar because the range aka total cost can be all the values in between 37.5 and 87.5. For #4  a reasonable domain value which is number of people is 3 because you can't have 2.5 people and you can't have -4 people and thus all of the above isn't possible leaving three. #5 is b because you can only have those set numbers to represent people. If you chose a that would mean you could have 1.5 people which isn't possible thus only numbers 2, 3, 4, 5, and 6 are possible. For #6 The answer is d because when you plug in numbers 2, 3, 4, 5, 6 into the x value one at a time and solve the equation, those numbers equal t. Just use your basic knowledge to figure these out there isn't much math you just have to know that domain means x and range means y. y is 9/10 always by itself on one side of the equal sign. When in doubt think, can I have a half a person. Think of the real world and apply to math. Goof luck on future problems!
