Studio = 7 yards by 4 yards

Area = 7*4 = 28 square yards.

Area of square carpet = 1 yard * 1 yard = 1 square yard

Number needed = Area of studio / Area of square carpet = 28 / 1 = 28

Number needed = 28

Find the constant of variation k for the direct variation 2x +6y = 0
scoray [572]
<span>A relationship between two variables in which one is a constant multiple of the other. The constant here is also called the constant of variation. In order to obtain this value, we manipulate the equation by isolating the variables. We do as follows:

</span><span>2x +6y = 0
y = -x/3

Therefore, the constant of variation is -1/3. Hope this answers the question. Have a nice day.</span>

You walk 3/8 miles to a music store. Then you walk another 1/3 miles to a clothing store. How many miles have you walked in all?
Rudik [331]

Answer:

You have walked \frac{17}{24} miles

Step-by-step explanation:

In order to add these two fractions, we must find a common denominator. In this case, I used 24

\frac{3}{8} +\frac{1}{3} \\\\\frac{9}{24} +\frac{8}{24} =\frac{17}{24}

1. The county fair charges $1.50 per ticket for the rides. Jermaine bought 20 tickets for the rides and spent a total of $48.75
MAVERICK [17]

Answer: Our variable be z for fair admission and our required linear equation will be

\$1.50x+z=\$48.75

Explanation:

Since we have given that

Cost per ticket for the rides =$1.50

Total amount she spent = $48.75

Let the total cost be y

Let the number of ride tickets be x

<u>a) Define your variable:</u>

Let the amount spent on fair admission be z

<u>b) Write a linear equation that can be used to determine the cost for ride tickets and fair admission:</u>

Our required equation will be

\$1.50x+z=\$48.75

Here, number of ride tickets = 20

So,

20\times 1.50+z=48.75\\\\30+z=48.75\\\\z=48.75-30=18.75

So, the cost for fair admission = $18.75

Suppose a2 + 4a + 3 represents the area of a rectangle. What is the perimeter of that rectangle? A) 2a + 4 B) 4a + 8 C) 6a + 12
allsm [11]
A² + 4a + 3
(a+3)(a+1)         This is the length and the width of the rectangle.

Perimeter = length + length + width + width
P = (a+3) + (a+3) + (a+1) + (a+1)
P = a + a + a + a + 3 + 3 + 1 + 1
P = 4a + 6 + 2
P = 4a + 8

B) 4a + 8
