The perimeter of a triangle is 29 millimeters. The length of the first side
is twice the length of the second side. The length of the third side is
5 more than the length of the second side. Find the side lengths of the
triangle. Then classify the triangle by its side lengths.

Answers

Answer 1

Answer:

7.25, 3.625, 18.125

Scalene triangle

Step-by-step explanation:

Turn the lengths into a ratio:

First side twice as long as second side

Third side 5 times as long as second side

First side : Second side  : Third side = 2 : 1 : 5

2 + 1 + 5 = 8

29 / 8 = 3.625

Multiply the ratio by 3.625:

3.625 x 2 = 7.25

3.625 x 1 = 3.625

3.625 x 5 = 18.125

The sides so not follow Pythagoras's theorem a² + b² = c² (c being the largest side, so it is not a right angled triangle  so it is a scalene triangle

A circular garden has a diameter of 28 feet. The garden is to be covered with peat moss. If each bag of peat moss covers 160 feet square, how many bags of peat moss will be needed?

Answers

Answer:

15.39 bags or 16 bags

Step-by-step explanation:

To get the area of a circular garden, you use the following formula:

area = pi * r^2

Plug in r = 28 feet:

area = pi * 28^2

area = about 2463 square feet

Each bag covers 160 sq ft, so divide:

2463 sq ft / 160 sq ft per bag

= 15.39 bags

But you can't have a partial bag, so round up to:

16 bags

Whats is 7 = 12v - 24?

Answers

Answer:

To the nearest tenth: v = 2.6

To the nearest hundredth: v = 2.58

Fraction form = 31/12

Step-by-step explanation:

1. Add 24 to both sides to cancel it out on the right

7 = 12v - 24

+24          +24

2. Divide each side by 12

31 = 12v

31/12 = 2.5833333

12/12 = 1v = v

v = 2.583333

It’s V=31/12

(1). 7=12v-24 (12v is a variable so you move it left hand side and change its sign)

(2). 7-12v=-24 (7 is a constant so move it to the right hand side and change its sign)

(3). -12v=-24-7 (now calculate the difference -24-7)

(4). Now it’s -12v=-31, now after that divide both sides of the equation by -12

(5). So the answer is V=31/12

The angles represented by the expressions (2x+46) and (3x-6) are complementary angles. find the measure of the larger angle. Im really confused. Could someone help.​

Answers

Answer:

66

Step-by-step explanation:

complimentary angles add up to 90 so:

3x-6 + 2x +46 = 90

5x +40 = 90

5x = 50

x = 10

2(10)+46 = 66

3(10) - 6 = 24

complementary angles add up to 90 so we want to add the two angles together and set it equal to 90° so 2x+46+3x-6=90
5x+40=90
5x=50
x=10
now that we know what X is we can figure out which angle is bigger and what your answer will be,
2(10)+46=66
3(10)-6=24
and to check our answer 66+24=90 so your answer is 66°
