Troy is making a flag shaped like a square. Each side measure 12 inches. He wants to add ribbon along the edges. He has 36 inches of ribbon. Does he have enough ribbon? Explain.

Answers

Answer 1

Answer:

The ribbon required to be combined is 48 inches but he had only 36 inches. so, he does not have enough ribbons.

Given that,

Troy is making a flag-shaped like a square.

Each side measure 12 inches.

He wants to add a ribbon along the edges. He has 36 inches of ribbon.

We have to determine,

Does he have enoughribbon?

According to the question,

A square has 4 sides, and all sides have the same length.

If one side measures 12 inches, then the total length of all sides is,

= 4 × 12 inches = 48 inches

All edges combined are a total of 48 inches.

He only has 36 inches of ribbon, so he does not have enough ribbon.

Hence, The ribbon required to be combined is 48 inches but he had only 36 inches. so, he does not have enough ribbons.

Answer 2

Answer: Since each side is 12 inches, then multiply 12 by 4 since it's a square and has 4 sides which makes 48.
48 is bigger than 36, so therefore, Troy does not have enough ribbon.

two mechanics worked on a car. The first mechanic worked for 10 hrs, and the second mechanic worked for 5 hours. Together they charged a total of $1475. What was the rate charged per hour by mechanic if the sum of the two rates was $190 per hour? What is the first mechanic make per hour? And what did the second mechanic make per hour?

Answers

Answer:

The first mechanic $90/hour and the second charged $70/hour

Step-by-step explanation:

Lets start off by letting x be the first mechanics rate and y being the second mechanics rate. We know that the first mechanic worked 5 hours and that the second mechanic worked 10 hours and together they charged 1150. An equation to express this would be:

5x+10y = 1150

We also know that together they charged 160/per hour. An equation to express this would be:

x+y = 160

Now we can solve the second equation for x or the first mechanics rate.

x+y = 160

x = 160 - y

Now that we have an expression for x we can plug that back into the first equation and solve for y or how much the second mechanic charged.

5x+10y=1150 plug in x =160-y

5(160-y)+10y=1150 Distribute

800 -5y+10y = 1150 Combine like terms

800 +5y = 1150 Subtract 800 from both sides

5y = 350 divide by 5

y = 70

So we know that the second mechanic charged $70/hour. We also know that(from our work before) that the first mechanic charges $160 - the rate the second mechanic charged. We know that's $70/hour so we can plug in and solve for the first rate.

x = 160-y

x = 160-70

x = 90

So we know that the first mechanic charged $90/hour and the second mechanic charged $70/hour.

Final answer:

The rate per hour for the first mechanic is $105 and for the second mechanic is $85.

Explanation:

This problem is a case of simultaneous equations where we need to determine the rates at which the two mechanics charge. Let's denote the hourly rates of the first and second mechanics as x and y respectively. From the question, we know:
1. x + y = $190 (The sum of the two rates was $190 per hour)
2. 10x + 5y = $1475 (The first mechanic worked for 10 hours and the second mechanic worked for 5 hours, and together they charged a total of $1475)

To solve these equations, you can start by multiplying the first equation by 5 to match the second equation:
5x + 5y = $950

Now, subtract this from the second equation:
10x - 5x = $1475 - $950
5x = $525

Therefore, x ($/hour by the first mechanic) = $525 / 5 = $105

You can now substitute x = $105 into the first equation to get:
$105 + y = $190
Therefore, y ($/hour by the second mechanic) = $190 - $105 = $85

Marty wants to plant grass in a rectangular section of his backyard. The section where he wants grass measures 6.62 meters by 4.55 meters. What is the area of this section? (Area = length × width) Do not round your answer.

Answers

Lets first look at the formula, then substitute for the formula, then solve. lets do it:-

A = lw
A = Area
l = lentgh
w = width

A = lw
l = 6.62 meters
w = 4.55 meters

A = lw
A = 6.62 × 4.55
A = 30.121 meters

So, the area of this section is 30.121 Meters.

Hope I helped ya!! xD

a=l×w
6.62m×4.55m
=30.121m

The area of a circle is 615.44 in2. What is the diameter of the circle? Use 3.14 for π.

Answers

The diameter of the circle is 28 inches.

Given:
Area of a circle = 615.44 in²

Area of a circle is computed by multiplying pi and the radius raised to the 2nd power.

A = π r²
615.44 in² = 3.14 * r²
615.44 in² / 3.14 = r²
196 = r²
√196 = √r²
14 in = r

Diameter is twice its radius. So, d = 2r; d = 2 * 14 ; d = 28 inches

Answer:

The diameter= 28in
