Answer:
Value of x = 5 feet
Step-by-step explanation:
Given:
Volume of cone = 75π cubic feet
Missing information;
Height of cone = 9 feet
Radius of cone = x
Find:
Value of x
Computation:
Volume of cone = (1/3)(π)(r²)(h)
75π = (1/3)(π)(x²)(9)
75 = (1/3)(x²)(9)
75 = (x²)(3)
x² = 75 / 3
x² = 25
x = √25
Radius of cone = 5 feet
Value of x = Radius of cone
Value of x = 5 feet

Answer:
0.88
Step-by-step explanation:
We would consider the first case second column....
So 14/16 will be the probability that comes out be approximately 0.88.

What are the domain restrictions of the expression g2+7g+12/g2−2g−24 ?
Given:
The expression is:
[tex]\dfrac{g^2+7g+12}{g^2-2g-24}[/tex]
To find:
The domain restrictions of the given expression.
Solution:
We have,
[tex]\dfrac{g^2+7g+12}{g^2-2g-24}[/tex]
To find the domain restrictions, we need to find the input values such that the denominator is equal to 0.
[tex]g^2-2g-24=0[/tex]
Splitting the middle term, we get
[tex]g^2-6g+4g-24=0[/tex]
[tex]g(g-6)+4(g-6)=0[/tex]
[tex](g-6)(g+4)=0[/tex]
Using zero product property, we get
[tex](g-6)=0[/tex] and [tex](g+4)=0[/tex]
[tex]g=6[/tex] and [tex]g=-4[/tex]
Therefore, the domain restrictions of the expression are -4 and 6. It means domain is set of all real numbers except -4 and 6.

∠A and \angle B∠B are vertical angles. If m\angle A=(7x-8)
∘
and m\angle B=(6x+17)
∘
, then find the value of x.
Answer:
x=25
Step-by-step explanation:
We know vertical angles are equal
<A = <B
7x-8 = 6x+17
Subtract 6x from each side
7x-6x-8 = 6x-6x+17
x-8 = 17
Add 8 to each side
x-8+8 = 17+8
x=25

Consider statements in the table shown. Select True or False for each statement about the sequences of transformations that can
verify that square ABCD is congruent to square A'B'C'D'.
True False
Square ABCD is translated 9 units to the right, followed by a translation 6 units down.
Square ABCD is reflected across the y-axis, followed by a translation 6 units down.
Square ABCD is translated 6 units down, followed by a translation 9 units to the right.
Answers:
TrueFalseTrue==========================================================
Explanation:
Point A is at (-3, 4). If we apply the translation rule of "shift 9 units to the right and 6 units down", then we apply this transformation
[tex](x,y) \to (x+9,y-6)[/tex]
We add 9 to the x coordinate and subtract 6 from the y coordinate.
So (-3,4) becomes (-3+9, 4-6) = (6, -2) which is where point A' is located in the diagram. You should find that points B,C,D all map to B', C', D' following this same translation rule.
Therefore, statement 1 is true.
Statement 3 is the same idea, but the order has been swapped. The order doesn't matter in this case. So that makes statement 3 true as well.
-----------------------------------------------
Statement 2 on the other hand is false
Why? Because a reflection reverses the orientation of a figure. Note how both squares ABCD and A'B'C'D' all go clockwise when we go through the alphabet (ie A to B to C to D).
If a reflection happened, then A'B'C'D' would go counterclockwise and show that the orientation has been swapped. I recommend drawing an analogue clock and going up to a mirror to see that the orientation has swapped.
To swap the orientation back, you need a second reflection. This shows that two reflections either lead to a translation or a rotation (depending if the mirror lines are parallel or not).
If you wanted, you could track to see where point B ends up if you follow statement 2. Point B is at (-1, 4). Reflect over the y axis to get to (1, 4). Then shift 6 units down to arrive at (1, -2) which is not the correct location of B'. The diagram shows B' is actually at (8, -2). So this is an alternative way to see how statement 2 is false.
Answer:
True
False
True
Step-by-step explanation:
Triangle ABC is going to be reflected over the y-axis.
If A is located at (4,3), where will A' be located?
Answer:
(-4, 3)
Step-by-step explanation:
There are coordinate rules for reflection that really help me with these:
Reflection over x-axis -- (x, y) -> (x, -y)
Reflection over y-axis -- (x, y) -> (-x, y)
Reflection over y = x -- (x, y) -> (y, x)
Reflection over y = -x -- (x, y) -> (-y, -x)
Hope this helps :]

When Zoe was six-year-old Lulu is twice her age Zoe is 10 years old now how old is Lulu
Answer: 20 years old
Step-by-step explanation: when Zoe was six years old, Lulu would have been 12 years old since Lulu's age is twice that of Zoe's. Since Zoe is now 10 years old, Lulu would have to be 20 years old since 10 multiplied by 2 equals 20.

Tillmon is the point guard for his basketball team. out of 63 attempts, tillmon scores 33 times.
Based on this information, what is his probability of scoring on his next shot?
A 1/2
B 10/21
C 11/21
D 3/6
Answer:
C. 11/21
Step-by-step explanation:
Find the probability that he scores in general, by dividing 33 by 63:
33/63
Simplify this by dividing the numerator and denominator by 3:
= 11/21
So, the probability that he will score his next shot is 11/21
The correct answer is C. 11/21

For two odd consecutive numbers, seven times the first number is 1 more than six times the greater number. What is the sum of those numbers?
9514 1404 393
Answer:
28
Step-by-step explanation:
Let x represent the even number between them. Then the desired sum is 2x.
The given relation is ...
7(x -1) = 1 +6(x +1)
x = 14 . . . . . . . add 7-6x
2x = 28 = sum of those numbers

You roll a die 42 times. The table shows the results. Find the experimental probability of rolling each number. Write each probability as a fraction in simplest form. For which number is the experimental probability of rolling the number the same as the theoretical probability?
p(one)=
p(two)=
p(three)=
p(four)=
p(five)=
p(six)=
no links, please
There are 6 numbers in a die.
So, theoretical probability of each no. = 1/6
P(1) = 7/42 = 1/6
P(2)= 6/42 =1/7
P(3) = 14/42= 1/3
P(4)= 4/42=2/21
P(5)= 6/42= 1/7
P(6)= 5/42
For no. 1 experimental probability of rolling the number the same as the theoretical probability
