A garden box has a perimeter of 18½ feet. If the length is 5 feet, what is the area of the garden box?
Travka [436]

Answer:

area=\frac{85}{4}feet^{2}

Step-by-step explanation:

1. Approach

Since it is given that the garden box is a rectangle, then the opposite sides are congruent. One can use this to their advantage, by setting up an equation that enables them to solve for the width of the rectangle. After doing so, one will multiply the width by the given length and solve for the area.

2. Solve for the width

It is given that the garden box is a rectangle. As per its definition, opposite sides in a rectangle are congruent. The problem gives the length and the perimeter of the rectangle, therefore, one can set up an equation and solve for the width.

perimeter=18\frac{1}{2}\\\\length=5

2(length+width)=perimeter

Substitute,

2(5+width)=18\frac{1}{2}

Conver the mixed number to an improper fraction. This can be done by multiplying the "number" part of the mixed number by the denominator of the fraction. Then add the result to the numerator.

2(5+width)=\frac{37}{2}

Inverse operations,

2(5+width)=\frac{37}{2}\\/2\\\\5+width=\frac{37}{4}\\-5\\\\width=\frac{17}{4}

3. Solve for the area

Now that one has solved for the width of the box, one must solve for the area. This can be done by multiplying the length by the width. Since the width is a fraction, one must remember, that when multiplying an integer by a fraction, one will multiply the integer by the numerator (the top of the fraction), and then simplify by reducing the fraction, if possible. Reducing the fraction is when one divides both the numerator and the denominator by the GCF (Greatest Common Factor).

length=5\\\\width = \frac{17}{4}

length*width=area

Substitute,

5*\frac{17}{4}\\\\=\frac{85}{4}

area=\frac{85}{4}feet^{2}

There are 24 pizzas. each person gets 1/3 of a pizza. how many people can be fed from the 24 pizzas?
ValentinkaMS [17]
Hello there.

<span>There are 24 pizzas. each person gets 1/3 of a pizza. how many people can be fed from the 24 pizzas?

Answer: There are 3 thirds in a whole.
Therefore 3 people could be fed by 1 pizza.
Since there are 24 , multiply 3 by 24.
3 x 24 =  72.
The number of people that could be fed from the 24 pizzas is 72.

Hope This Helps You!
Good Luck Studying ^-^</span>

4) The triangle on the right is an equilateral <br><br> Find the value of X and Y
ozzi

Answer:

<em>angle Y is 29 degrees</em>

<em>angle X is 120 degrees</em>

Step-by-step explanation:

Well, if the triangle is an equilateral, then all the angles are equal to

60 degrees

that means the the angle at the top point is 60+31 = 91 degrees

the right point is 60 degrees

every triangle has 180 degrees total

180 - (91+60) = 29 degrees

NOW FORGET ABOUT THE EQUILATERAL FOR A BIT

180 = 31+x+29

simplify

180 = 60+x

subtract 60 from both sides

120 = x

The width of a rectangle is 2 less than twice the length, x. If the perimeter is 44, what is the width?
Butoxors [25]

Take the length as 'x'

Width = 2x - 2

Perimeter = 44 [ Formula = 2(l + w) ]

2 (l + w) = 44

2 (x + 2x - 2) = 44

2 (3x - 2) = 44

6x - 4 = 44

6x = 44 + 4

6x = 48

x = 48/6

<u>x </u><u>=</u><u> </u><u>8</u> => length

Width = 2x - 2 = 2(8) - 2 = <u>1</u><u>4</u><u> </u><u>units.</u>

Hope it helps!

At the end of the study, the sociologist had a sample of 500 expectant parents. He estimates that there are 6 million expectant
sertanlavr [38]

If at the end of the study, the sociologist had a sample of 500 expectant parents and he estimates that there are 6 million expectant parents in the United States then the value of n is 500.

Given that the sample size is 500 and the number of expectant parents be 6 million.

We are required to find what n represents and value of n.

The value of n is 500. Small n shows the sample size and capital N shows the size of population.

Sample is that part of the population that represents the characteristics of the whole population.

Population is the number of individuals present in the area which a researcher wants to observe.

Hence if at the end of the study, the sociologist had a sample of 500 expectant parents and he estimates that there are 6 million expectant parents in the United States then the value of n is 500.
