Answer:
x = 7
Step-by-step explanation:
The triangles are similar
12/8 = (x+3+5)/(x+3) cross multiply expressions
12x + 36 = 8x + 64
12x - 8x = 64 - 36
4x = 28 divide both sides by 4
x = 7

Find the volume of this sphere.
I need help I don’t understand.
Answer:
2048
Step-by-step explanation:
Formula for volume of a sphere is given:
V = 4/3πr^3
Where r = radius
The sphere shown has a given radius of 8
All we have to do to find the volume of the sphere is simply plug in the given value of the radius (8) into the volume of a sphere formula
(Note it says use 3 for π )
V = 4/3(3)r^3
Substitute 8 for r
V = 4/3(3)(8)^3
Plug this into a calculator and you get that the volume is 2048
Answer:
2,048in³
Step-by-step explanation:
The formula to find the volume of the sphere is already given to you in the problem. All we need to do is substitute and solve.
V = 4/3π(8)³
V = 4/3π(512)
V ≈ 682.67(3)
V ≈ 2,048

A total of 585 tickets were sold for the school play. They were either adult tickets or student tickets. There were 65 fewer student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
325
Step-by-step explanation:
Total Tickets = 585
Let the adult tickets be = x
If 65 fewer student tickets were sold than adult tickets then Student tickets = x-65
Student Tickets + Adult Tickets = 585
x + (x-65) = 585
x + x - 65 = 585
2x - 65 = 585
2x = 585 + 65
2x = 650
2x/2 = 650/2
x = 325

In a co-educational school, 47 of the students are girls. If there are 324 boys, find the number of girls in the school.
Answer:
The total number of girls is 47.
Step-by-step explanation:
Below are the following values:
Total number of students = girls + boys
Total number of students = 47 + 324
Total number of students = 371
We are required to find the number of girls in the school.
Since a total number of boys is 324 and thus total number of girls is 47.

Answer:
1/12
Step-by-step explanation:
The probability of any given outcome is the ratio of the number of ways that outcome can happen to the total number of outcomes.
P(4) = 1/6 . . . . . roll = 4 is one of 6 possible outcomes
P(odd) = 3/6 = 1/2 . . . . . of the 6 possible outcomes, 3 are odd
__
The two rolls of the die are presumed to be independent, so the probability of the two outcomes is the product of their individual probabilities.
P(4 & odd) = (1/6)(1/2) = 1/12

Answer:
19.3
Step-by-step explanation:
The base of the top triangle is 24.158 (approximately) found from the bottom triangle using the sine rule
from that,
sin(53) = r/24.158
or, r = 24.158×sin(53)
or, r = 19.3 (rounded to the nearest tenth)
In a car dealership, all of the vehicles are either
a sedan or a SUV. If 36 sedans are sold and 36
SUVs are added, there will be an equal number
of sedans and SUVs. If 8 SUVs are sold and 8
sedans are added, there will be twice as many
sedans as SUVs. How many sedans were at the
dealership before any vehicle was sold?
Answer:
The number of sedans before any vehicle was sold is 168
Step-by-step explanation:
Let's define the variables:
x = number of sedans
y = number of SUVs
We know that:
"If 36 sedans are sold and 36 SUVs are added, there will be an equal number of sedans and SUVs"
If 36 sedans are sold, the new number of sedans is:
x - 36
if 36 SUVs are added, the new number of SUVs is
y + 36
And these numbers are equal, then:
x - 36 = y + 36
We also know that:
" If 8 SUVs are sold and 8 sedans are added, there will be twice as many
sedans as SUVs. "
If 8 SUVs are sold, the new number of SUVs will be:
y - 8
If 8 sedans are added, the new number of sedans wil be:
x + 8
From this we can write the equation:
(x + 8) = 2*(y - 8)
x + 8 = 2*y - 16
Then we have two equations:
x - 36 = y + 36
x + 8 = 2*y - 16
We want to find the number of sedans, x, then we need to isolate the other variable in one of the equations, let's isolate y in the first one:
Let's isolate x in the first one:
x - 36 - 36 = y
x - 72 = y
Now we can replace it in the other equation:
x + 8 = 2*y - 16
x + 8 = 2*(x - 72) - 16
Now we can solve this for x.
x + 8 = 2*x - 144 - 16
8 + 144 + 16 = 2x - x
168 = x
The number of sedans before any vehicle was sold is 168

A horizontal line has a slope of 0.
A vertical line has a undefined slope.
Any other line will have a slope of some number.
Answer:
D
Step-by-step explanation:
The slope of a line represents the number of units a line rises or falls vertically for each unit of horizontal change from left to right.
1) A line with positive slope (m > 0) rises from left to right.
2) A line with negative slope (m < 0) falls from left to right.
3) A line with zero slope is horizontal (parallel to x-axis).
4) A line with undefined slope is vertical (parallel to y-axis).
Ans: The line is parallel to y-axis. So, the slope is undefined

For the question below, you will need to find the GCF of 45 and 60. In this instance it is 5, so it will be outside the box. The GCF answers will be inside the parenthesis, which is 7 and 12.
45x + 60 = 5(7x + 12)
In this question you have to multiply 2 with every number inside the parenthesis. So 2 × 10x and 2 × 4.

c. -77 < f(x) < -2
d. 8 < f(x) < 23
Answer:
[tex]choice \: c. \: - 77 < f(x) < - 2[/tex]
Step-by-step explanation:
Find the y-values of the functions endpoints.[tex]f( - 4) = - 5 ({ - 4}^{2}) + 3 = - 77[/tex]
[tex]f( - 1) = - 5( { - 1}^{2}) + 3 = - 2[/tex]
Thus finding the range of F(x).
The range of the given function is - 77 < f(x) < - 2.
What is the range of a function?"The range of a function is a set of all the images of elements in the domain."
The given function is:
f(x) = - 5x² + 3
It is defined over the domain - 4 < x < - 1.
For x = - 4, f(x) = - 5(- 4)² + 3 = - 80 + 3 = - 77
For x = - 1, f(x) = - 5(- 1)² + 3 = - 5 + 3 = - 2
Therefore, the range of the given function f(x) is:
- 77 < f(x) < - 2.

Which of the following is an arithmetic sequence? 1, -3, 9, -27,... -2, 4, -6, 8, ... -8, -6, -4, -2, ... 2, 4, 8, 16, ...
Answer:
Given the proposed interrogate, the answer(s) to the following are identified as “-8, -6, -4, -2…” and “2, 4, 8, 16”.
Step-by-step explanation:
Accountable Conditions: Although the question implies there is only one individual mathematical statement which fits the conditions stated in the interrogate, both sequences listed above fit such, thus are both correct.
To evaluate for such, a comprehension of an “Arithmetic Sequence” is obligated:
In arithmetic sequences, the presence of a consecutive deviation or fixed pattern must be consistent and present throughout each and individual number or value contained within the particular set.
For Example: 3, 5, 7, 9, 11, 13, …
The deviation, or the number required to produce the subsequent value is identified as +2.
Now, apply such definitions to the peculiar problem:
A. 1, -3, 9, -27,… has -4, +12, -36, hence is not consistent. Thus, A cannot be correct.
B. -2, 4, -6, 8,… has +6, -10, +14, hence does not obtain a persistent consecutive pattern.
C. -8, -6, -4, -2… has +2, +2, +2, hence is consistent. Thus, C is correct.
D. 2, 4, 8, 16,… has +2, +2, +2, hence is consistent. Thus, D is correct.
