Which of these rotations will map an equilateral triangle to itself?(1 point)
45°
60°
90°
120°
Answer:
120°
Step-by-step explanation:
The equilateral triangle is the triangle that has three sides equal also they are congruent to each other and each side has an angle of 60 degrees
Now for rotation it would be a map to itself at 120 degrees counterclockwise
So the same is to be considered
Hence, the last option is correct
And, the other options are incorrect

When adding 32.6 to a certain number, the sum is 36.14, as seen below. What number should go in the box to complete the addition problem?
36.14÷16=
Answer:
3
Step-by-step explanation:
because
32.6 + 1.54 = 34.14
32.6 + 2.54 = 35.14
32.6 + 3.54 = 36.14

When I am 6 my brother is half my age. How old will my brother be when I am 70?
Answer:
67
Step-by-step explanation:
Your brother is three years younger than you, so when you're 70, he'll be three years younger, 67.
~theLocoCoco
Answer:
35 years old
Step-by-step explanation:
Since your brother is half your age, that means it should be exact. 70 is not a number than would have an even split, so you would have to have either an odd number such as 5. 40 plus 40 is 80, which is to high. 30 plus 30 is 60, too low. 35 plus 35 is 70 exact. Hope this helped! Also, I dont know if this was trick question, either way, he should be half. So if you were 10, he would be 5. If you were 18, he would be 9.

To raise funds for a trip, members of a high school math club are holding a game night in
the gym. They sell tickets at $5 per person. The gym holds a maximum of 250 people.
The amount of money raised is a function of the number of tickets sold.
Which statement accurately describes the domain of the function?
all numbers less than 250
all integers
all positive integers
all positive integers less than or equal to 250
Answer:All positive integer less than or equal to 250
Step-by-step explanation: Teacher told me so
The correct option for the given situation is option C i.e. all positive integers.
What is Integers?
An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.
Here, Price of per ticket = $ 5
Maximum number of people = 250.
Total amount of fund raised = $ 5 X 250
= $ 1250
Thus, The correct option for the given situation is option C i.e. all positive integers.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3y = -2x
y = x - 5
Step 2: Solve for x
Substitution
Substitute in y: 3(x - 5) = -2xDistribute 3: 3x - 15 = -2xAdd 2x on both sides: 5x - 15 = 0Add 15 on both sides: 5x = 15Divide 5 on both sides: x = 3Step 3: Solve for y
Define equation: y = x - 5Substitute in x: y = 3 - 5Subtract: y = -2Answer:
y = -2
x = 3
Step-by-step explanation:
First plug in the y= x-5 equation into the 3y = -2x so that it looks like this:
3(x-5)=-2x
Second after distributing the 3 to the x and -5 you will have an equation that looks like this: 3x -15 = -2x
Then you have keep the x's on one side so you add 2x to both sides and add 15 as well so now you have: 5x = 15
Divide both sides by 5 and get x = 3
To find y, you plug x=3 in in to the y = x-5 and get that y = -2
calculate the angles of a triangle if the angle alpha is 16 ° greater than the angle beta and the angle gamma is 52 ° smaller than the beta GIVING BRANLIEST***
Answer:
88°, 72°, 20°Step-by-step explanation:
Angle alpha is 16° greater than the angle beta:
α = β + 16°Angle gamma is 52° smaller than the beta:
γ = β - 52Sum of angles is 180°, substitute α and β:
α + β + γ = 180°β + 16° + β + β - 52° = 180°3β - 36° = 180°3β = 216°β = 216°/3β = 72°Then
α = 72° + 16° = 88°γ = 72° - 52° = 20°A geometric sequence is shown below.

What is an explicit representation for the nth term of the sequence?
A.f(n)=12(−4)n
B. f(n)=−12(4)n−1
C. f(n)=−12(4)n
D. f(n)=12(−4)n−1
Answer:
An explicit representation for the nth term of the sequence:
[tex]f_n=-\frac{1}{2}\cdot \:4^{n-1}[/tex]
It means, option (B) should be true.
Step-by-step explanation:
Given the geometric sequence
[tex]-\frac{1}{2},\:-2,\:-8,\:-32,...[/tex]
A geometric sequence has a constant ratio, denoted by 'r', and is defined by
[tex]f_n=f_1\cdot r^{n-1}[/tex]
Determining the common ratios of all the adjacent terms
[tex]\frac{-2}{-\frac{1}{2}}=4,\:\quad \frac{-8}{-2}=4,\:\quad \frac{-32}{-8}=4[/tex]
As the ratio is the same, so
r = 4
Given that f₁ = -1/2
substituting r = 4, and f₁ = -1/2 in the nth term
[tex]f_n=f_1\cdot r^{n-1}[/tex]
[tex]f_n=-\frac{1}{2}\cdot \:4^{n-1}[/tex]
Thus, an explicit representation for the nth term of the sequence:
[tex]f_n=-\frac{1}{2}\cdot \:4^{n-1}[/tex]
It means, option (B) should be true.

Heather opened a lemonade stand on her street. It costs her $5.25 to buy the supplies each day, and she sells lemonade for $1.50 a cup. If she wants to make at least $100.00 in profits (sales - expenses) each day, what is the minimum number of cups of lemonade Heather needs to sell? Input your answer as a whole number.
Answer:
around 66.66
Step-by-step explanation:
hope this helps
Answer:
70 cups
Step-by-step explanation:
C. P. of lemonade supplies = $5.25
S. P. of one cup of lemonade = $1.50
Let us assume that she should sell n cups of lemonade to make a profit of $100.00.
Therefore, S. P of n cups = $1.50n
Since,
Profit = S. P. - C. P.
Therefore,
100 = 1.5n - 5.25
100 + 5.25 = 1.5n
105.25 = 1.5n
n = 105.25/1.5
n = 70.1666667
n = 70 cups

Factor the expression.
A. ++
Answer:
(x+4) * (x+3)
Step-by-step explanation:
To factor the general expression:
X²+ax+c
We need to find the numbers b and d of the factoring expression:
(x+b) * (x+d)
Where:
b*d = c
b+d = a
For the expression:
X²+7x+12
We need to find b and d that:
b+d = 7
b*d = 12
If b = 4 and d = 3, the expression could be:
(x+4) * (x+3) = X² + 4x + 3x + 12 = X² + 7x +12
Which expression below is equivalent to -3x+5(x+2).

On a blueprint, the length of a wall is 5 centimeters. If the actual length of the wall is 15 feet, what is the scale of the blueprint
Answer:
1 cm = 3 feet.
Step-by-step explanation:
Divide 15 by 5 to get 3; on the blueprint, every centimeter represents 3 feet.
The scale of scale factor of the blueprint is 1 cm = 3 feet.
What is a scale factor?The scale factor defines a variable in a ratio of two different measurements.
Sometimes drawings of large models are represented in a scale factor of a smaller unit.
Given, On a blueprint, the length of a wall is 5 centimeters and the actual length of the wall is 15 feet.
Therefore, The scale factor of the blueprint is,
= (5/15).
= 1/5.
So, It can be written as 1 cm = 3 feet.
