can someone help me with this pls​

Answer:

She must score 90 points

Step-by-step explanation:

Find the average of the first 2 tests

76 + 80 = 156

Divide the sum of the first 2 tests by how many tests there were

156 ÷ 2 = 78

Multiply 82 by 3

82 x 3 = 246

Subtract 156 from 246

246 - 156 = 90

Add all the numbers together to get the average

90 + 80 + 76 = 246

246 ÷ 3 = 82

Hope this helps!

Answer:

AC = 15.52 centimeters

Step-by-step explanation:

Step 1) Determine the definition of the Pythagorean Theorem.

According to the Pythagorean Theorem, the square of the length of the hypotenuse of any right triangle equals the sum of each of the legs squared.

Step 2) Apply the theorem to the problem.

In this specific situation, AB and BC are the legs of the right triangle, while AC is the hypotenuse. This means that AB^2 + BC^2 should equal AC^2.

Step 3) Create an equation based on the formula.

The equation should look like this:

AB^2 + BC^2 = AC^2

4^2 + 15^2 = AC^2

16 + 225 = AC^2

241 = AC^2

AC = [tex]\sqrt{241}[/tex]

AC = 15.52 centimeters

Answer is None of the above

Step-by-step explanation:

First we distribute the 4 amongst everything inside the parentheses.

(Remember that when we distribute numbers, we are basically multiplying them.)

So now we have: 4x - 856 = -3.7

Next we do: 856 + (-3.7), and that gives us 852.3

Finally, we divide both sides by 4 in order to isolate the x-value.

Our answer is now x = 213.075

Hope this helps you :)

Answer:

45 degrees

Step-by-step explanation:

Vertical angle 105, so we put it on the other side. We then do 105+30+(Angle 1)=180, because all lines add up to 180, and we get angle 1=45

please consider brainliest!

Answer:

45

Step-by-step explanation:

the line will be 180 degrees so we already got 30. Then we have two lines that seem to be vertical so both 105. You add 105+35=135 then 180-135=45

Answer:

There could be 30 kids in the gym class.

Step-by-step explanation:

If there were 30 total kids, 12 would be boys(6*2) and 18 would be girls(6*3).  Any number that is divisible by 5 would work because 2+3=5.

The expression can be used to show the length of one side of the triangle is 4x+6.

Given

An equilateral triangle has a perimeter of 12 x + 18 units.

The perimeter of the Equilateral Triangle is simply the sum of its three sides which are equal in length. Perimeter is denoted by the P symbol.

[tex]\rm Perimeter= 3 \times S[/tex]

Therefore,

The expression that can be used to show the length of one side of the triangle is;

[tex]\rm Perimeter = 12x+18\\\\Perimeter = 3(4x+6)[/tex]

Hence, the expression can be used to show the length of one side of the triangle is 4x+6.

To know more about the Perimeter of the Equilateral triangle is given below.

[Let me know if there is another method your instructor wanted you to use]

Step-by-step explanation:

Given:

[tex]3x^2+5x+2=0[/tex]

Factor using the quadratic formula:

[tex]x=\frac{-b+-\sqrt{b^2-4(a)(c)} }{2a}[/tex]

[tex]x=\frac{-5+-\sqrt{(5)^2-4(3)(2)} }{2(3)}[/tex]

[tex]x=\frac{-5+-\sqrt{25-24} }{6}[/tex]

[tex]x=\frac{-5+-\sqrt{1} }{6}[/tex]

[tex]x=\frac{-5+1}{6}[/tex] and [tex]x=\frac{-5-1}{6}[/tex]

Finally:
