Answer:
40
Step-by-step explanation:
Because these angles are the same, we can make an equation, 5x-5=3x+13.
2x - 18 = 2 • (x - 9)
Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : x-9 = 0
Add 9 to both sides of the equation :
x = 9
Replace x with 9 in this equation, 3(9) + 13
27+13
=40
Write an equation for the line in slope-intercept form
The slope of the line is 3. The y-intercept is (0,4)
Answer:
y - 4 = 3(x - 0)
y - 4 = 3x - 0
y = 3x + 4

Which method can you use to prove these triangles congruent?
Answer: The HL Theorem.
Step-by-step explanation: We are given that the triangles have a congruent 90 degree angle and two congruent sides. This would indicate towards SAS but in this case, that doesn't work because the angle is not in between the two congruent sides. We know that the triangles are right, and that their hypotenuses are congruent and that one leg is congruent. Thus, the answer must be HL (hypotenuse & leg).

What is the volume of this sphere?
Use ≈ 3.14 and round your answer to the nearest hundredth.
4 ft
Rounded to the nearest hundredth, the volume of the sphere with a radius of 4 ft is approximately 267.95 cubic feet.
The formula for the volume V of a sphere is given by:
[tex]\[V = \frac{4}{3} \pi r^3\][/tex]
Given:
Radius r = 4 ft
Let's calculate the volume using the given radius:

The probability that Babe Ruth hits a home run on any given at-bat is 0.12, and each at-bat is independent.
Part A: What is the probability that the next home run will be on his fifth at-bat? (5 points)
Part B: What is the expected number of at-bats until the next home run? (5 points)
Answer:
A) 0.072 = 7.2%
B) 8.3333 at-bats (8 to 9 at-bats)
Step-by-step explanation:
A)
If the chance of hitting a home run is 0.12, the chance of not hitting a home run is 1 - 0.12 = 0.88.
To find the probability of the next home run being in the fifth strike, we need the four other strikes to not be a home run, so the probability is:
P = (0.88)^4 * 0.12 = 0.072 = 7.2%
B)
To find the expected number of at-bats until the next home run, we just need to divide 100% by the probability of hitting a home run (0.12 = 12%):
100/12 = 8.3333
So the expected number is 8 to 9 at-bats

The sum of three consecutive integers is 9.
1. Determine the variable.
2. Identify key words and translate their meanings.
3. Write the multistep equation for the scenario.
Use the variable n to represent the first integer. Finish translating to identify the third integer.
1st integer: n
2nd integer: n + 1
3rd integer: n + _
To solve for three consecutive integers whose sum is 9, we can express the integers as n, n + 1, and n + 2. Using the equation n + (n + 1) + (n + 2) = 9, we find that n = 2. Therefore, the three consecutive integers are 2, 3, and 4.
Explanation:To solve for three consecutive integers whose sum is 9, we can start by expressing the integers in terms of a variable. Let's use the variable n to represent the first integer.
The second integer would then be n + 1, and the third integer would be n + 2.
The sum of these three integers is given as 9, so we can write the equation n + (n + 1) + (n + 2) = 9.
Simplifying the equation by combining like terms, we get 3n + 3 = 9. Subtracting 3 from both sides, we have 3n = 6. Finally, dividing both sides by 3, we find that n = 2.
Therefore, the three consecutive integers are 2, 3, and 4.

Solve the equation 1/4 a =3
Answer:
a=12
Step-by-step explanation:
To solve, we need to isolate the variable, a
1/4a =3
To do this, divide both sides by 1/4, or multiply both sides by the reciprocal of 1/4: 4/1
4(1/4a)=3(4)
The 4 and 1/4 will cancel out
a=12
Answer:
a = 12
Step-by-step explanation:
1/4 a = 3
Multiply each side by 4
1/4a*4 = 3*4
a =12

Five years ago, Nina was twice as old as Sam. In five years, she will be 1.5 times as old as Sam. How old are Nina and Sam now?
Answer:
Nina is 25, Sam is 15
Step-by-step explanation:
5 years ago, Nina was 2S, and Sam was S.
In 5 years, she will be 1.5S and Sam is S.
In a span of 10 years, she will be 0.5S less.
20, 10 5 years ago
Currently, 25 and 15 years.
30 and 20 years in 5 years.
20*1.5=30
By solving from an expression Nina is currently 25 years old and Sam is currently 15 years old.
What is an expression?In mathematics, an expression is a combination of one or more numbers, variables, constants, and operators, which when evaluated, produce a value. Expressions can include mathematical symbols such as addition, subtraction, multiplication, division, exponents, roots, logarithms, and trigonometric functions.
Let's start by assigning variables to their current ages. Let N be Nina's current age and S be Sam's current age.
We know from the first sentence that 5 years ago, Nina was twice as old as Sam. So we can set up an equation based on that:
N - 5 = 2(S - 5)
Expanding the right side:
N - 5 = 2S - 10
N = 2S - 5
Now we can use the second sentence, which tells us that in 5 years Nina will be 1.5 times as old as Sam.
N + 5 = 1.5(S + 5)
Expanding the right side:
N + 5 = 1.5S + 7.5
N = 1.5S + 2.5
We have two equations, one for N in terms of S and one for N in terms of S. We can set them equal to each other:
2S - 5 = 1.5S + 2.5
Solving for S:
0.5S = 7.5
S = 15
So Sam is currently 15 years old. We can use either equation to find Nina's age:
N = 2S - 5
N = 2(15) - 5
N = 25
So Nina is currently 25 years old.

Gary has (10x + 7) dollars if gary decides to buy two pairs of jeans write an expression that represents how much money gary will have left over after the purchase then simplify your expression
The expression (2x + 17) represents how much money Gary will have left over after purchasing two pairs of jeans.
To find out how much money Gary will have left over after purchasing two pairs of jeans, we need to subtract the cost of the jeans from the total amount Gary has.
Total amount Gary has = (10x + 7)
Cost of two pairs of jeans = (2(4x - 5))
Now, subtract the cost of jeans from the total amount:
Leftover money = (10x + 7) - 2(4x - 5)
Let's simplify this expression:
Leftover money} = 10x + 7 - (8x - 10)
Leftover money} = 10x + 7 - 8x + 10
Leftover money} = 2x + 17
So, the expression (2x + 17) represents how much money Gary will have left over after purchasing two pairs of jeans.

Circle A: center (2, 3) and radius 5. Circle B: center (-1, 4) and radius 10. Which of the
following is the necessary transformation (translation; dilation) from B to A to prove
that the two circles are similar?
Answer:
see explanation
Step-by-step explanation:
The centre of circle B requires to be coincident with centre of circle A
(- 1, 4 ) → (2, 3 )
That is a translation of < 3, - 1 >
This ensures that the circles are concentric ( have the same centre )
radius of B is 10 and radius of A is 5, thus
dilatation = [tex]\frac{5}{10}[/tex] = [tex]\frac{1}{2}[/tex]
