Tenaya earned 82 points on one math test and 94 points on the next test. Elena earned 94 points on the first test and then 82 po
jek_recluse [69]

Answer:

Total test score of Tenaya and Elena are same.

Step-by-step explanation:

Given:

Points earned by Tenaya on one math test = 82

Points earned by Tenaya on next math test = 94

Points earned by Elena on first math test = 94

Points earned by Elena on next math test = 82

We need to Compare the total test scores for Tenaya to the total scores for Elena.

Solution:

First we will find the Total test score of Tenaya and Elena.

Now we can say that;

Total test score of Tenaya is equal to sum Points earned by Tenaya on one math test and Points earned by Tenaya on next math test.

framing in equation form we get;

Total test score of Tenaya  = 94+82 = 176\ points

Total test score of Elena is equal to sum Points earned by Elena on one math test and Points earned by Elena on next math test.

framing in equation form we get;

Total test score of Elena  = 94+82 = 176\ points

Hence from we can say that Total test score of Tenaya and Elena are same.

Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varie
kodGreya [7K]

Answer:

New power = 88 Kw (Approx.)

Step-by-step explanation:

Given:

P = a(v³)

Old power p = 700 Kw

Old wind speed v = 12 m/s

Find:

New power when v = 6m/s

Computation:

P = a(v³)

700 = a(12³)

a = 0.4050 m²

New power = a(v³)

New power = (0.4050)(6³)

New power = 87.48

New power = 88 Kw (Approx.)

The area of a storage shed floor is 20 ft2. The length is 3 more than twice the width. Find the dimensions of the storage shed f
vladimir1956 [14]

Answer:

  • 2.5 ft wide
  • 8 ft long

Step-by-step explanation:

The given relation between length and width can be used to write an expression for area. The equation setting that equal to the given area can be solved to find the shed dimensions.

__

<h3>Given relation</h3>

Let x represent the width of the shed. Then the length is (2x+3), and the area is ...

  A = LW

  20 = (2x+3)(x) . . . . . area of the shed

__

<h3>Solution</h3>

Completing the square gives ...

  2x² +3x +1.125 = 21.125 . . . . . . add 2(9/16) to both sides

  2(x +0.75)² = 21.125 . . . . . . . write as a square

  x +0.75 = √10.5625 . . . . . divide by 2, take the square root

  x = -0.75 +3.25 = 2.50 . . . . . subtract 0.75, keep the positive solution

The width of the shed is 2.5 feet; the length is 2(2.5)+3 = 8 feet.

Answer:

Hello! A function is easily identified when an x value does not have more than 1 y value. a y value can have as many x values to infinity, but x can only have one y.

Example...

x                       y
