If an equilateral triangle has a height of 8 metres find the length of each side. Round your answer to 2 decimal places.

Answers

Answer 1

Answer:

9.24 m to 2 DP's.

Step-by-step explanation:

Consider the right triangle formed from a side , altitude and 1/2 the base.

By pythagoras:

x^2 = 8^2 + (0.5x)^2     where x is the length of each side.

x^2 - 0.25x^2 = 64

0.75x^2 = 64

x^2 = 64/0.75 =  85.3333.

x = 9.2376 m.

Answer:

Step-by-step explanation:

18. x + 25 = 55

     x = 30

19. 2x - 5 = 95

     2x = 100

      x = 50

20. 3x - 22 = 2x + 26

     x - 22 = 26

     x = 48

21. 3x - 18 + 105 = 180

    3x + 87 = 180

    3x = 93

      x = 31

22. 19x + 17x = 180

      36x = 180

       x = 5

   27(5) = 135

23. 5x + 40 + 2x = 180

7x + 40 = 140

7x = 140

x = 20

5(20) = 100

2(20) = 40

5(20) + 40 = 100 + 40 = 140

Algebra I

Terms/Coefficients

Step-by-step explanation:

We know that Frank has 2 gardens, one with y vegetable seeds and another with 3y + 8 vegetable seeds. If we are trying to find the total amount of seeds planted, we must add the 2 gardens together:

Garden 1: y

Garden 2: 3y + 8

Garden 1 + Garden 2 = Total veggie seeds

y + 3y + 8 = Total veggie seeds

Total veggie seeds = 4y + 8

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 6% vinegar, and the second brand contains 11% vinegar. The chef
wants to make 200 milliliters of a dressing that is 9% vinegar. How much of each brand should she use?

Answers

Answer:

The chef will use 120 milliliters of 11% vinegar, and 80 milliliters of 6% vinegar.

Step-by-step explanation:

Since a chef is going to use a mixture of two brands of Italian dressing, and the first brand contains 6% vinegar, and the second brand contains 11% vinegar, and the chef wants to make 200 milliliters of a dressing that is 9% vinegar, to determine how much of each brand should she use the following calculation must be performed:

100 x 0.11 + 0 x 0.06 = 11

90 x 0.11 + 10 x 0.06 = 10.5

80 x 0.11 + 20 x 0.06 = 10

70 x 0.11 + 30 x 0.06 = 9.5

60 x 0.11 + 40 x 0.06 = 9

200 x 0.6 = 120

200 x 0.4 = 80

Thus, the chef will use 120 milliliters of 11% vinegar, and 80 milliliters of 6% vinegar.
