Answer:
x = 9
Step-by-step explanation:
(7x + 2)
7x can't be added with 2 because 2 has no x
therefor ,
we take x out
X ( 7 + 2 )
so
X = 9

You roll a 6 sided die. what is P?
Answer:
Finding the probability of a single die roll requires little effort.
First, remember that by definition, a prime is an integer with precisely two factors: 1 and the number itself (which is why 1 does not qualify: it has only one factor). The numbers from 6 on down that fit the bill are {2,3,5}. Since there are six sides, your answer is:
P(prime) = 3/6 = 1/2 = 50%

GIVING BRAINLIEST TO THE PERSON THAT CAN EXPLAIN THIS THE BEST (:
Answer:
25π-24
Step-by-step explanation:
from the figure,
radius of the circle(r)=diameter of the circle(d)/2
=10/2
=5
Area of the circle(A)=πr^2
=π5^2
=25π
Again,
base of the right angle triangle(b)=6
perpendicular of right angle triangle(p)=8
we also know,
the area of right angle triangle = 1/2*base*height
=1/2*6*8
=1/2*48
=48/2
=24
Now, Area of the shaded region=Area of circle - Area of right angle triangle (given in the figure)
Area of shaded region= 25π -24

The cosine of one acute angle of a right triangle is 817.
What is the sine of the other acute angle?
The sine of the other acute angle is 15/17 if the cosine of one acute angle of a right triangle is 8/17.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a cosine of one acute angle of a right triangle is 8/17.
Let's suppose the angle is α
[tex]\rm Cos\alpha = \frac{8}{17}[/tex]
As we know the cos is the ratio of adjacent to hypotenuse and Sin is the ratio of the opposite to hypotenuse.
Let's suppose the length of the hypotenuse is x units
From the Pythagoras theorem:
[tex]\rm 17^2=x^2+8^2[/tex]
x = 15 units
Now the Sin ratio:
[tex]\rm Sin\alpha = \frac{15}{17}[/tex]
Thus, the sine of the other acute angle is 15/17 if the cosine of one acute angle of a right triangle is 8/17.

a spherical tank holds 8,000 ft^3 of water. What is the diameter of the tank?
Answer:
24.8 ft
Step-by-step explanation:
Formula to find the volume of a sphere is :
Volume = [tex]\frac{4}{3}[/tex] π r³
Here,
r ⇒ radius
Given that,
Volume ⇒ 8000 ft³
Let us find the radius of the tank now.
Volume = [tex]\frac{4}{3}[/tex] π r³
8000 = [tex]\frac{4}{3}[/tex] π r³
8000 = [tex]\frac{4}{3}[/tex] × 3.14 × r³
8000 × 3 = 4 × 3.14 × r³
24000 = 12.56r³
Divide both sides by 12.56.
1910.822 = r³
∛1910.822 = r
12.40 ft = radius
And now let us find the diameter of the sphere.
d = 2r
d = 2 × 12.40
d = 24.8 ft
The diameter of the tank is 24.80 ft
Step-by-step explanation:
Given-
A spherical tank holds 8,000 ft^3 of wateri.e. The volume of spherical tank = 8,000 ft^3
Now, the formula for finding volume of any spherical figure is-
[tex] \boxed{\mathfrak{ \purple{volume \:of \: sphere = \frac{4}{3} \pi {r}^{3} }}}[/tex]Therefore, substituting value, we get
[tex]⇢8000 = \frac{4}{3} \pi {r}^{3} [/tex]
[tex]⇢8000 \times \frac{3}{4 } = \frac{22}{7} \pi {r}^{3} [/tex]
Transposing 4/3 to left hand side ,it will become 3/4 . And Here, 8000 will get cancelled by 4 leaving 2000
[tex]⇢2000 \times 3 \times \frac{7}{22} = {r}^{3} [/tex]
Similarly , On performing further calculations, we get. ..
[tex]⇢ \frac{21000}{11} = {r}^{3} [/tex]
[tex]⇢1910.822 = {r}^{3} [/tex]
[tex]⇢ \sqrt[3]{1910.822} = r[/tex]
[tex]⇢ \underline{12.40 = r}[/tex]
Thus, the radius of the tank is 12.40 ft
Now,
The diameter of the tank = 2 × radius
[tex] \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 12.40[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: = 24.80[/tex]
•°• The diameter of the tank comes out 24.80 ft

A former residential complex was found to be a Superfund site polluted with several hazardous materials. Tamela is an investigative journalist who would like to show whether the proportion of the residents of the complex who eventually died from cancer is greater than the regional average of 14%. She randomly selects 54 residents who lived in the complex and finds that 12 of those residents eventually died from cancer. Are all of the conditions for this hypothesis test met, and if so, what are the null and alternative hypotheses for this hypothesis test?
Considering the situation described, we have that:
The null hypotheses is [tex]H_0: p = 0.14[/tex].The alternative hypotheses is [tex]H_1: p > 0.14[/tex].What are the hypotheses tested?At the null hypotheses, it is tested if the proportion at the complex is the same as the rest of the population, that is, of 14%, hence:

Write 2 at the top of your division problem, subtract 150 by 165 short form of 1,659150 - 165 = 15(9) the 9 comes from dropping the ones place in 1,659
Reconsider how many times 75 goes into 1,659(22) and since we do not have any other numbers, we write 150 and 159, because again, 1,659 has to help us solve the problem by dropping the ones place.150 - 159 = 9

What are linear equations?Linear equations are relations between two expressions having their degree less than or equal to 1.
How do we solve the given question?In the question, we are given that the sum of a number and 12 is 21.
We are asked to find the number.
We assume the number to be x.
∴ The sum of a number and 12 is expressed using the expression: x + 12
This expression is equal to 21, which can be represented by the linear equation: x + 12 = 21.
To find x, we solve this linear equation using the given steps:
Equation: x + 12 = 21
Subtract 12 from both sides of the equation: x + 12 - 12 = 21 - 12
∴ x = 9.
∴ The number that makes the sum of 21 when added with 12 is 9. Found solving the linear equation x + 12 = 21. Hence, option B is the right choice.

Transformation involves changing the position of a shape through translation, dilation, rotation and reflection.Marcus's claim is correct.
What is transformation?A process by which one figure, expression, or function is converted into another one of similar value.
The triangles are given as: ΔTSR and ΔUSV
By comparison, we can see that point S is on both triangles, and this point on both triangles corresponds.
So, to map ΔTSR to ΔUSV, then ΔTSR must be rotated about point S to ΔUSV or rotate ΔUSV about point S to ΔTSR.

Which statement correctly compares the average number of eggs laid per day for each barn?
By taking the average number of eggs for both barns, we will see that the correct option is A.
How to get the average?
For a set of N elements {x₁, x₂, ..., xₙ} the mean is given by:
[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]
For barn 1, the set is {2, 5, 5, 6}
So the mean is:
M1 = (2 + 5 + 5 + 6)/4 = 4.5
For the barn 2, the set is {3, 6, 8, 9}
So the mean is:
M2 = (3 + 6 + 8 + 9)/4 = 6.5
Now, taking the quantity 100%(M2 - M1)/M1 we get:
100%*(6.5 - 4.5)/4.5 = 44%
So the average in barn 2 is around 50% larger than the average in barn 1. Then the correct option is A.

To draw the graph plot the 3 points and you should be able to draw a straight line through them.
Answer:
The first y value with -3, is 1.
The second y value with 0, is -2.
The third y value with 4, is -6.
A graph is shown below.
Step-by-step explanation:
It states that the rule is y = -x-2. So all we do is plug in the values shown in the table.
y = -(-3)-2
y = 1
The first point of intersection is at (-3,1)
y = -(0)-2
y = -2
The second point of intersection is at (0,-2)
y = -(4)-2
y = -6
The third point of intersection is at (4,-6)
So now, we plot the points, and draw a line connecting them all.
