Answer:
x = 4
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
1.5(x + 4) - 3 = 4.5(x - 2)
1.5x + 6 - 3 = 4.5x - 9
1.5x - 4.5x = -9 - 6 + 3
-3x = -12
x = -12/-3
x = 4

What is a net and how can you use it to help you find the surface area of a 3-Dimensional figure?
84 points for brainliest!
Answer:Surface Area of a Solid
The surface area of a 3-dimensional object is the measure of the total area of all its faces. This means that one way to find the surface area of a solid is to find the area of its net. The surface area of a rectangular prism is the area of the six rectangles that cover it.

Answer:
2000 m²2827 m²B. MarciStep-by-step explanation:
It is convenient to compute the areas in terms of grid squares. Then those results can be converted to square meters by multiplying by the area of a grid square: (10 m)² = 100 m².
(a) The area of the school is the product of its side dimensions. The short side is (in terms of grid squares) ...
W = √(1²+3²) = √10
The long side is ...
L = √(2²+6²) = √40
Then the area is ...
A = LW = (√40)(√10) = √400 = 20
The area of the school is 20 grid squares = 2000 m² . . . . . where s = 10 m
__
(b) The area of the museum is given by the formula ...
A = πr² = π(3)² = 9π grid squares = 2827 m²
The area of the museum is 2827 m².
__
(c) Marci says the museum has a larger area than the school. She is correct.
Marci should win the debate.

Mr. Wilson wants to build a square roof for his square deck in the back yard.
The roof will be 12 feet long on each side. He uses the formula (A = s) to
find the area of the roof. What will be the area of the square roof on Mr.
Wilson's deck? (give only the number value of your answer) *
Answer:
The area of the square roof is 144 square feet.Step-by-step explanation:
Givens
He wants to build a square roof.The roof will be 12 feet long.We know that the area of a square is
[tex]A=s^{2}[/tex]
Where [tex]s=12 \ ft[/tex], according to the problem.
Replacing this value, we have
[tex]A=(12 \ ft)^{2} =144 \ ft^{2}[/tex]
Therefore, the area of the square roof is 144 square feet.
Answer: the area of the roof is 144 feet squared for each side (up and down), adding to a total of 288 ft^2
Step-by-step explanation:
If the roof is a square with a side lenght L = 12 feet, then we use the fact that the area of a square is equal to the square of the side lenght of the square, this is:
A = L^2 = (12 ft)^2 = 144 ft^2
Now, Mr. wilson uses the equation A = s, this is because the roof has 2 surfaces, one up and one bottom, then the total area is 2 times the value that we find earlier:
2*144 ft^2 = 288 ft^2

Find an equation equivalent to r = 10 sinθ in rectangular coordinates
Answer:
[tex]x^{2} + y^{2} - 10\cdot y = 0[/tex]
Step-by-step explanation:
The following expressions are used to transform from polar into rectangular form:
[tex]r = \sqrt{x^{2}+y^{2}}[/tex]
[tex]\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex]
Now, the variables are substituted and equation is finally simplified:
[tex]\sqrt{x^{2}+y^{2}} = 10\cdot \frac{y}{\sqrt{x^{2}+y^{2}} }[/tex]
[tex]x^{2}+y^{2} = 10\cdot y[/tex]
The equivalent equation in rectangular coordinates is:
[tex]x^{2} + y^{2} - 10\cdot y = 0[/tex]

Answer:
C. [tex]F(x) = -x^2 - 3[/tex]
Step-by-step explanation:
The function, F(x), has flipped over the x-axis (as seen) meaning that the function has to have a negative sign in front. The function has also shifted downwards 3 units, meaning that 3 has to have been subtracted from the function.
This makes "C," the correct answer, as it fulfills these requirements.

Imagine we wanted to investigate whether the reason for quitting smoking affects success rate. We recruited a sample of 120 smokers. Half wanted to quit to improve their appearance (yellow teeth and bad breath, etc) and half wanted to quit to improve their health (life expectancy, etc). After six months we measured how successful they had been at quitting smoking. The data were skewed, so we ran a Mann-Whitney test on the data (output below)
a) People who wanted to quit smoking to improve their appearance (M= 66.91) were significantly more successful at quitting than those who wanted to quit to improve their health (M= 54.09), U = -2.04, z = 188.57, p = .04
b) People who wanted to quit smoking to improve their appearance did not significantly differ from those who wanted to quit to improve their health, U = 1415.50, z = -2.04, p = .04
c) People who wanted to quit smoking to improve their health were significantly more successful at quitting than those who wanted to quit to improve their appearance, U = 1415.50, z = -2.04, p = .04
d) People who wanted to quit smoking to improve their appearance were significantly more successful at quitting than those who wanted to quit to improve their health,, U = 1415.50, z = -2.04, p = .04.

r = [tex]\frac{d}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2 inches
Solve for x: 1/2(6x - 10) = 2x - 7
Answer:
X=-2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/2(6x-10)=2x-7
(1/2)(6x)+(1/2)(-10)=2x+-7(Distribute)
3x+-5=2x+-7
3x-5=2x-7
Step 2: Subtract 2x from both sides.
3x-5-2x=2x-7-2x
X-5=-7
Step 3: Add 5 to both sides.
X-5+5=-7+5
X=-2

Out of 120 students at a pep rally 15 did not wear green. What percent of students at the rally did wear green
Answer:
87.5%
Step-by-step explanation:
First we find the number of students that did wear green which is 120-15=105. Then we need to find what percentage of these students who did wear green so we divide 105 by 120 which is .875. To find this number in percent form, we multiply this number by 100 which gives us 87.5%.
Answer:
87.5%

b)14°
c)24°
d)31°
Answer:
b) 14°
Step-by-step explanation:
To solve this, you need to make an equation. since a line is equal to 180°, you can add the two angles together. for example, x+96+5x=180. you would write this because these two angles are on a line, which makes the total sum 180°. now you solve: 6x+96=180. 6x=84. x=14°. :)
