Answer:

72 units squared

Step-by-step explanation:

6x2=12

10x6=6

60+12=72

Answer:

x = 8

Step-by-step explanation:

51° = 4x + 19

32° = 4x

8 = x

Answer:

x = 8

Step-by-step explanation:

well, 4 x something + 19 = 51

51-19=32

32/4=8

so your answer is 8

4 x 8 + 19 = 51

Answer:

2 -- True

0 -- True

-3 -- True

-4 -- False

-6 -- False

Step-by-step explanation:

When solved the inequality, 3x + 7 > -5, it would turn out to be x > -4

Anything greater than -4 is a solution.

Answer:

18

Step-by-step explanation:

12, 15, 16, 16, 20, 22, 24, 27

The average of 16 and 20 is 18

Answer:

$0.20

Step-by-step explanation:

if you divide 2.40 by 12 you get 0.20, which is the answer

Answer:

106

Step-by-step explanation:

Bring the values to one side and change the signs

Always substitute in brackets

_=136+(-30)

106=136-30

Thus your answer is 106

Answer:

10*sin(40)=AC

Step-by-step explanation:

[tex]sin(x)=\frac{opposite}{hypotenuse}[/tex]

so

here it says

[tex]sin(40)=\frac{AC}{10}[/tex]  multiply both sides by 10

[tex]10*sin(40)=AC[/tex]

Complete Question:

Lucas is planting grass on the shaded portions of the yard. What will be the total area of covered by grass? Fill in the missing.

Part A= 12 x ? = ? ft²

Part B= 0.5 x ? x 9 = ?ft²

Part C= 0.5 x 7 x ? = ?ft²

Total Area= ?ft²

Answer:

[tex]A = 108ft^2[/tex]

[tex]B = 27ft^2[/tex]

[tex]C = 24.5ft^2[/tex]

[tex]Area = 159.50ft^2[/tex]

Step-by-step explanation:

Given

See attachment

From the attachment;

Part A is a rectangle with dimension 9ft by 12ft

So,

[tex]A = 12ft * 9ft[/tex]

[tex]A = 108ft^2[/tex]

Part B is a triangle with dimension: height = 6 and base = 9

The height is calculated as:

[tex]Height = 12ft - 6ft = 6ft[/tex]

And the base is:

[tex]Base = 18ft - 9ft = 9ft[/tex]

So, the area is:

[tex]B = 0.5 * 6ft * 9ft[/tex]

[tex]B = 27ft^2[/tex]

Part C is a triangle with dimension: height = 7 and base = 7

So, the area is:

[tex]C = 0.5 * 7 * 7ft^2[/tex]

[tex]C = 24.5ft^2[/tex]

Total Area is:

[tex]Area = A + B + C[/tex]

[tex]Area = 108ft^2 + 27ft^2 + 24.5ft^2[/tex]

[tex]Area = 159.50ft^2[/tex]

Step-by-step explanation:

Std Error Mean – Standard Error Mean is the estimated standard deviation of the sample mean. This value is estimated as the standard deviation of one sample divided by the square root of sample size: 9.47859/sqrt(200) = . 67024, 10.25294/sqrt(200) = . 72499.

Answer:

c*(t)-((t-2)*(t+6)*(t-4))=0

Step-by-step explanation:

ct -  ((t - 2) • (t + 6) • (t - 4))  = 0

ct -  (t - 2) • (t + 6) • (t - 4)  = 0

3.1    ct-t3+28t-48  is not a perfect cube

ct - t3 + 28t - 48  = 0

Solve   ct-t3+28t-48  = 0

Answer:

Step-by-step explanation:

Area of a triangle is 1/2 * b * h

b = base, the one labeled b on the diagram

h = height, the dotted line in the middle

so, you do pythagorean theorem with a and b to find the dotted line

a² + b² = h² (h is for height)

h = [tex]\sqrt{a^{2} +b^{2}}[/tex]

Then, you just plug in the numbers from question 3 to find h and then you do

1/2 * b * h

Answer:

Whenever you see a letter beside a number, just know you should multiply that number by the letter. So z = 4, then 2z = 2×4, and x = 5, then 2× 5.

so : 2×4 = 8 - 2×5

so : 8-10

so the answer would then be -2.

Answer:

The right solution is "-8.25".

Step-by-step explanation:

The given values are:

Sampled people,

n = 150

Null and alternative hypotheses will be:

[tex]H_0:p=0.53[/tex]

[tex]Ha:p\neq 0.53[/tex]

The z-statistics will be:

⇒ [tex]z=\frac{\bar{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }[/tex]

On substituting the values, we get

⇒    [tex]=\frac{0.2-0.53}{\sqrt{\frac{0.53(1-0.53)}{150} } }[/tex]

⇒    [tex]=\frac{-0.33}{\sqrt{\frac{0.24}{150}} }[/tex]

⇒    [tex]=\frac{-0.33}{0.04}[/tex]

⇒    [tex]=-8.25[/tex]

Answer:

we need to know whats given above can you show us a picture of the table above?

Step-by-step explanation:

Answer: 1

Step-by-step explanation:

Rewrite as (i^4)^6

Rewrite i^4 as 1

Rewrite i^4 as (i^2) ^2

((i^2)) ^2)6

Rewrite i^2 as -1

((-1) ^2) 6

Raise -1 to the power of 2

1^6

One to any power is 1.

Answer:

104

Step-by-step explanation:

Hey There!

So essentially what this problem is asking us to do is solve for the missing angle in a triangle

Remember all of the angles in a triangle will add up to 180

so to find the missing angle we subtract the given angles (38 and 38) from 180

180-38-38=104

so we can conclude that angle A equals 104

Answer:

x = 5 / 3 = 1.667

Step-by-step explanation:

8*x+10-5*x-(15)=0

Solve  :    3x-5 = 0

Add  5  to both sides of the equation :

                     3x = 5

Divide both sides of the equation by 3:

                    x = 5/3 = 1.667

x = 5/3 = 1.667

Answer:

D - 9 students

Step-by-step explanation:

For this problem, you need to find the percentage of students left. Subtracting all the percentages you already know, you get 100 -  30 - 20 - 10 - 10, or 30. Since there are 30 students in the class, 30 percent of 30 is 9 students.

Hopefully this helps- let me know if you have any questions!
