Answer:
Step-by-step explanation:
A ride on the roller coaster costs 4 tickets while the boat ride only costs 3 tickets. Michael went on the two rides a total of 10 times and spent a total of 37 tickets.
A table titled Ride Tickets, showing Times on the Ride, Tickets per Ride, and Total Tickets. The first row shows Roller Coaster, with r, 4 and 4 r. The second row shows Boat Ride, with 10 minus r, 3, and 3 left parenthesis 10 minus r right-parenthesis. The third row shows, Total, with 10, blank, and 37.
Which equation is true?
r(10 – r) = 10
r + (10 – r) = 4 + 3
4r[3(10 – r)] = 37 this is your answer
4r + 3(10 – r) = 37
Which relation is a function
Answer:
A function is a relation in which each input has only one output.
Step-by-step explanation:
In the relation Y is a function of X because for each input x(1,2,3 or 0) there is only one output y.
The relation that is a function is the relation (d)
Checking the relations that are functionsFrom the question, we have the following parameters that can be used in our computation:
The relations (1) to (4) represent the given parameter (see attachment)
Next, we test the options
Relation (a)
This relation is not a function
This is because it fails the vertical line test i.e. some output values all point to the same input value,
Relation (b)
This relation is not a function
This is because it fails the vertical line test i.e. some output values all point to the same input value,
Relation (c)
This relation is not a function
This is because it fails the vertical line test i.e. some output values all point to the same input value,
Relation (d)
This relation is a function
This is because the inputs all point to different output values
Hence, the option (d) is a relation

The dotplot shows the heights of 25 students in Mrs. Navard’s statistics class.
A) Find the Percentile for Lynette, the student who is 65 in. tall.
B) Ashers height is at the 88th percentile of the distribution. Interpret this value in context. How tall is Asher?
Answer:
A)Percentile for Lynette, the student who is 65 in. tall is 36th
B) Asher is 22 inches tall.
Step-by-step explanation:
Percentile : It is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls
A) Find the Percentile for Lynette, the student who is 65 in. tall.
No. of students below 65 inch =9
So, Percentage of data below 65 inch =[tex]\frac{9}{25} \times 100 = 36 \%[/tex]
So, Percentile for Lynette, the student who is 65 in. tall is 36th
B)Ashers height is at the 88th percentile of the distribution. Interpret this value in context. How tall is Asher
[tex]88=\frac{x}{25} \times 100 \\\frac{2200}{100}=x[/tex]
22=x
So, No. of students below or st 88th percentile = 22
So, Asher is 22 inches tall.

Ana angle measure 79.8 degrees less than the measure of it’s complementary angle what is the measure of each angle
Answer:
x = 129.8 degrees, y = 50.2 degrees, x + y = 180
Step-by-step explanation:
Let's say you have 2 supplementary angles, x and y
So x + y = 180
if x is 79.8 degrees less than the measure of a supplementary angle, then x = y - 79.8
Putting this into our x + y = 180 equation, we get
(y - 79.8) + y = 180
2y - 79.8 = 180
2y = 180 + 79.8
2y = 259.8
y = 259.8/2 = 129.9 degrees.
so x = 129.9 - 79.6 = 50.3 degrees.
See if it worked. x = 129.9 degrees, y = 50.3 degrees, x + y = 180 so we found the correct two angles! :-)

What is the inverse of the function f(x) = 2x – 10?
Answer:
f^-1(x) = (x+10) / 2
Step-by-step explanation:
sooo
f(x) = 2x - 10
y = 2x - 10
x = 2y - 10
x + 10 = 2y
y = (x + 10) / 2
f^-1(x) = (x+10) / 2
Answer:
[tex]f^{-1}(x)=\frac{x+10}{2}[/tex]
Step-by-step explanation:
[tex]f(x)=2x-10\\\\y=2x-10\\\\x=2y-10\\\\x+10=2y\\\\\frac{x+10}{2}=y\\ \\f^{-1}(x)=\frac{x+10}{2}[/tex]

7) Find the base of a triangle whose height is 12cm, and area is 96cm? Your answer
Answer:
16 cm
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Substitute given information into the formula:
96= ½ ×base ×12
Simplify:
96= 6 ×base
Divide both sides by 6:
base= 96 ÷6
base= 16 cm
Answer:
16 cm[tex] \\ [/tex]
Step-by-step explanation:
It is given that, the height of a triangle is 12cm, and its area is 96cm² and we have to find the base of triangle.

To find the base of the triangle, we have to know this formula :
[tex] \\ {\longrightarrow \pmb{\frak {\qquad \frac{1}{2} \times Base \times Height = Area_{(Triangle)} \:}}} \\ \\[/tex]
Now, substituting the values in the formula :
[tex]{\longrightarrow \pmb{\sf {\qquad \frac{1}{2} \times Base \times 12 = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad \frac{1}{ \cancel2} \times Base \times \cancel{12 } = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad {1} \times Base \times 6 = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad Base \times 6 = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad Base = \frac{96}{6} \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\frak {\qquad Base = 16\:}}} \\ \\[/tex]
Therefore,
The base of the triangle is 16 cmSimplify 6 - 2^3 + (-9 + 5) • 2.

The banana bread card states it serves 10 people. How much flour is required to make enough bread for 30 people?
========================================================
The card says we need 1 & 1/2 cups of flour
Let's convert this to decimal form
1 & 1/2 = 1 + 1/2
1 & 1/2 = 1 + 0.5
1 & 1/2 = 1.5
The mixed number 1 & 1/2 is equivalent to the decimal number 1.5
Now multiply this by 3. This is because the recipe originally serves 10 people, but we want to serve 3 times as many people (3*10 = 30 total).
So, 3*1.5 = 4.5
Now convert back to a mixed number
4.5 = 4 + 0.5
4.5 = 4 + 1/2
4.5 = 4 & 1/2
We'll need 4 & 1/2 cups of flour.
----------------------
Here's another way to approach the problem
Multiply 3 by 1 & 1/2 to get
3*(1 & 1/2) = 3*(1 + 1/2)
3*(1 & 1/2) = 3*1 + 3*1/2
3*(1 & 1/2) = 3 + 3/2
3*(1 & 1/2) = 3 + (2+1)/2
3*(1 & 1/2) = 3 + 2/2 + 1/2
3*(1 & 1/2) = 3+1 + 1/2
3*(1 & 1/2) = 4 + 1/2
3*(1 & 1/2) = 4 & 1/2

what is the measure of 6?
explain why please
please anwser this asap.
Statement Reason
1. 3x + 7 = ∠2 (Vertically opposite angles)2. ∠2 = ∠5 (Corresponging angles)3. ∠5 = ∠6 (Vertically opposite angles)⇒ ∠2 = ∠5 = ∠6 = 3x + 7
Looking at the picture, we can see that ∠6 and 4x + 5 are a linear pair.
Finding the value of x:
⇒ ∠6 + 4x + 5 = 180
⇒ 3x + 7 + 4x + 5 = 180
⇒ 7x + 12 = 180
⇒ 7x = 180 - 12
⇒ 7x = 168
⇒ 7x/7 = 168/7
⇒ x = 168/7 = 24
Now, substitute the value of x into the expression "3x + 7" to find ∠6.
Finding the measure of ∠6:
⇒ ∠6 = 3x + 7
⇒ ∠6 = 3(24) + 7
⇒ ∠6 = 72 + 7
⇒ ∠6 = 79°

6x - 10y = 20 in slope intercept form
The general equation of a straight line in slope-intercept form is given as:
y = mx + c
The slope-intercept form of 6x - 10y = 20 is y = (3/5)x - 2.
What is equation of a line?The equation of a line is a form of representing the set of points, which form a line in a coordinate system.
The general equation of a straight line is given as:
y = mx + c,
where m = slope of the line and c = y-intercept.
We have,
6x - 10y = 20 _____(1)
The slope intercept form is y= mx + c
So,
Subtract -6x on both sides.
6x - 10y - 6x = 20 - 6x
-10y = 20 - 6x
Divide both sides by -10.
y = 20/-10 + 6x/10
y = -2 + 3x/5
y = (3/5)x - 2
Thus,
The slope-intercept form of 6x - 10y = 20 is y = (3/5)x - 2.

Devaughn is 14 years older than Sydney. The sum of their ages is 110. What is Sydney's age?
Answer:
The answer would be 48
Sydney is 48
Devaughn is 62
48 + 62 = 110
Okays so you start by doing the equation 110 - 14 = 96
then dividing 96 by 2 (96 ÷ 2) which is 48
add 14 to 48 and you will get 62. We can automatically assume that sydney is 48 because when you add 48 to 62, you will get 110. I hope that this helps! ^‿^

Dominic goes jogging every morning. If m represents the number of miles he jogs each day, which expression represents the total number of miles he jogs in a week?
7 m
7 + m
7 minus m
StartFraction 7 over m EndFraction
Answer:
The expression which represents the total number of miles he jogs in a week is 7 m ⇒ A
Step-by-step explanation:
Let us solve the question
∵ Dominic goes jogging every morning
∵ m represents the number of miles he jogs each day
→ That means he jogs m miles every day
∵ There are 7 days in a week
→ That means he jogs m miles every day for 7 days
∵ m + m + m + m + m + m + m = 7 × m
∴ He jogs in 1 week 7 × m miles
∴ He jogs 7 m miles in a week
The expression which represents the total number of miles he jogs in a week is 7 m
