You and four friends go to a baseball game. The total
cost is $110. How much did each ticket cost? One step word problem HELP ME PLEASEEE
Step-by-step explanation:
You and four friends = 5 people
To see how much one ticket costs we have to divide the total amount spent by the number of people who bought tickets.
Total amount spent: $110
People who bought tickets:5
110÷5=22
Each ticket cost $22
Answer:
$110÷5
=$22
therefore each ticket costs $22

prove that if a is a factor of b and b is a factor of c, then a is a factor of c
Answer:
The set of numbers a = 3, b = 6, and c = 9 proves the hypothesis because 3 is a factor of 6 and 3 is a factor of 9. Property 1 states that therefore 3 is a factor of 9 + 3 =12, which we know is true because 3 × 4=12. You can prove that this property is true for all integers if you know what the term factor means.

Identify the domain of the function shown in the graph.
y
10
10
10
-10
A. X20
B. All positive real numbers
C. All real numbers
D. All positive integers
The domain of the function shown in the graph are all real numbers. Therefore, option C is the correct answer.
What is domain and range of the function?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.
The coordinate points from the given graph are (-2, 0) and (10, 6).
Here, slope m=(6-0)/(10+2)
= 6/12
= 1/2
= 0.5
Substitute m=0.5 and (x, y)=(-2, 0) in y=mx+c, we get
0=0.5(-2)+c
0=-1+c
c=1
So, equation of a line is y=0.5x+1
Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain.
Domain: (−∞,∞),{x|x∈R}
Range: (−∞,∞),{y|y∈R}
Therefore, option C is the correct answer.

A 6-kilogram bag of cement costs $24.81. What is the unit price, rounded to the nearest cent?
Answer:
$4.14
Step-by-step explanation:
To find the unit price, we divide $24.81 by 6.
24.81/6 = 4.135
The question says to round to the nearest cent so we round it to 4.14.
4.135 = 4.14

Solve the following proportion. Round your answer to two decimal places.
Answer:
x = 2
Step-by-step explanation:
[tex]\frac{x+1}{x+3}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
5(x + 1) = 3(x + 3) ← distribute parenthesis on both sides
5x + 5 = 3x + 9 ( subtract 3x from both sides )
2x + 5 = 9 ( subtract 5 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2

Megan will multiply the first equation by 3 then add the result to the second equation.
What will be the resulting system of equations that produces the same solutions?
The resulting equation will be x + y = 4 and 4y =20
System of equationGIven the system of equation given as:
x + y = 4
-3x + y = 8
If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:
3x + 3y = 12
-3x + y = 8
Adding both equation
3y + y = 12 + 8
4y = 20
Hence the resulting equation will be x + y = 4 and 4y =20

Step-by-step explanation:
Formula:
V = (4/3)π r^3
Knowns:
r = 3.4
Work:
- (4/3)π 3.4^3 ≈ 164.64 cm^3
- Now, round .6 to a 1 because it is >4, this turns 164.64 cm^3 into 165 cm^3

can someone explain this to me? i’m not for sure how to solve it. will mark brainliest
Answer:
x = 2√2
y = 2√6
Step-by-step explanation:
Consider the ratio of the two legs of the two smaller interior right triangles. (refer to attached diagrams for the triangles - I have outlined one in blue and the other in red)
These will be equal since the triangles are similar
shorter leg : longer leg
(blue triangle = red triangle)
⇒ x : 4 = 2 : x
⇒ x/4 = 2/x
⇒ x² = 8
⇒ x = √8
⇒ x = 2√2
Now we have x, we have the two legs of the right triangle with hypotenuse labelled y.
Using Pythagoras' Theorem a² + b² = c² (where a and b are the legs and c is the hypotenuse)
⇒ 4² + (2√2)² = y²
⇒ y² = 24
⇒ y = √24
⇒ y = 2√6

Find a polynomial F(x ) of degree 5 that has the following zeros.
8(multiplicity 2) -2, -9, 0
Leave your answer in factored form.
F(x) = ?
Answer:
f(x) = x(x + 2)(x + 9)(x - 8)²
Step-by-step explanation:
Given x = h is a zero of f(x) then (x - h) is a factor
If h has multiplicity 2 then the factor is squared , that is (x - h)²
here the zeros are x = 8 of multiplicity 2 , x = - 2, x = - 9, x = 0
then (x - 8)² , (x - (- 2)) , (x - (- 9)) , x - 0 are the factors, that is
(x - 8)² , (x + 2) , (x + 9) and x
f(x) = x(x + 2)(x + 9)(x - 8)² ← in factored form

Answer:
64.4
Step-by-step explanation:
In one of the trig formulas, it states sin <a/A = sin<b/B = sin<c/C
So we have in this case:
sin(70)/12 = sin x/14 Note: x is just a variable for the angle <ABC
14(sin70)/12 = sin x
sin^-1(14(sin70)/12) = x
x=64.4
