It cost $36.75 for three tickets to visit the science center. It cost $51 for 4 tickets to visit the zoo. Which attraction will cost more money for a group of 12 students to visit? How much more?
Answers
36.75 ÷ 3 = 12.25
Multiply the product with 12 to get the cost of 12 tickets.
12.25 × 12 = 147
Find the cost of 1 zoo ticket.
51 ÷ 4 = 12.75
Find the cost of 12 tickets by multiplying the product and 12
12.75 × 12 = $153
12 Science Center Tickets cost $147
12 zoo tickets cost $153
The Zoo costs more than the Science Center.
To find out how much more the Zoo costed, subtract 147 from 153.
153 - 147 = 6
The zoo only costs $6 more for 12 students.
So, you're answers are Zoo and $6

David wants to start a lawn care business. He offers his clients two different service options: Plan A charges $20 per month plus $5 an hour. Plan B charges $30 per month plus $3 an hour. He used the system of equations below to determine how much money he can make on both plans. y = 5x + 20 y = 3x + 30 If x represents the number of hours he works, and y represents the total money he makes, how many hours would he have to work to make the same amount of money with both plans?
Answers
Answer:
1440 hrs
Step-by-step explanation:
5 is the number of hours he works, and 45 is the total money David makes.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that David offers his clients two different service options.
Plan A charges $20 per month plus $5 an hour.
Plan B charges $30 per month plus $3 an hour.
y = 5x + 20 and y = 3x + 30 are the system of equations to determine how much money he can make on both plans.
y = 5x + 20..(1)
y = 3x + 30..(2)
Substitute equation 2 from equation 1.
y-y=5x+20-3x-30
0=2x-10
2x=10
Divide both sides by 2
x=5.
Now substitute x in equation 1.
y=25+20
y=45
Hence, 5 is the number of hours he works, and 45 is the total money David makes.

-12y^10
Step-by-step explanation:
First let's rewrite the equation using the commutative property of multiplication
3 x (-4)y^8y^2
Multiply y^8 by y^2 by adding the exponents
y^8+y^2= y^10
3 x (-4)y^10
Now multiply 3 by -4
3 x -4= -12
Finally put them together
-12 + y^10= -12y^10
Answer:
[tex] - 12 {y}^{10} [/tex]
Step-by-step explanation:
We are to simplify:
[tex](3 {y}^{8} )( - 4 {y}^{2} )[/tex]
3 multiplies -4 to get -12, as shown below
[tex]3 \times - 4 = - 12[/tex]
Now, to multiply the exponents which are 8 and 2, we have to use the exponential rule of multiplication: [tex] {a}^{b} \times {a}^{c} = {a}^{b + c} [/tex]
Therefore:
[tex] {y}^{8} \times {y}^{2} = = > {y}^{8 + 2} = {y}^{10} [/tex]
Now, combine -12 and [tex] {y}^{10} [/tex] to get your final answer.
Final answer [tex] = - 12 {y}^{10} [/tex]

(04.01 MC) A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 10 inches. Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 10) would represent a height of 10 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points) Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points) Part C: If the rate at which the candle burned was 0.75 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values. (3 points)
Answers
The ordered pairs, justification of the function with different order pairs is required.
The ordered pairs are [tex](0,10),(1,9.5),(2,9),(3,8.5),(4,8),(5,7.5)[/tex]
All values of [tex]x[/tex] has a unique value in [tex]y[/tex] so, it is a function.
y = Height of candle
x = Number of hours
m = Rate = 0.5 inches per hour
c = y intercept = Initial height = 10 inches
The required function is
[tex]y=-0.5x+10[/tex]
Six ordered pairs would be
[tex]x=0,1,2,3,4,5[/tex]
[tex]y=-0.5\times 0+10=10[/tex]
[tex]y=-0.5\times 1+10=9.5[/tex]
[tex]y=-0.5\times 2+10=9[/tex]
[tex]y=-0.5\times 3+10=8.5[/tex]
[tex]y=-0.5\times 4+10=8[/tex]
[tex]y=-0.5\times 5+10=7.5[/tex]
The ordered pairs are
[tex](0,10),(1,9.5),(2,9),(3,8.5),(4,8),(5,7.5)[/tex]
It can be seen that all values of [tex]x[/tex] has a unique value in [tex]y[/tex] so, it is a function.
If m = 0.75 inches per hour
The function would change to
[tex]y=-0.75x+10[/tex]
Some ordered pairs would be
[tex]y=-0.75\times 0+10[/tex]
[tex]y=-0.75\times 1+10[/tex]
[tex](0,10),(1,9.25)[/tex]

Find the scale factor of trapezoid QRST if it’s dilated to Q’R’S’T’. Type your result in the empty box provided below. HELPP PLEASE!!!!!!
Answers
Answer:
5 units
Step-by-step explanation:
its hard to tell but i think it dilated 5 units
We want to find the scale factor at which QRST is dilated to form Q'R'S'T'
We will find that the scale factor is 2.
In a general dilation, we will see that all the measures change in the same way, by the scale factor.
This means that:
QR*k = Q'R'
RS*k = R'S'
And so on, where k is the scale factor.
Then we can just find one of the equivalent measures in both trapezoids and find the value of k.
For example, we have:
Q'R' = 8
QR = 4
Replacing these on the above equation we get:
4*k = 8
k = 8/4 = 2
k = 2
The scale factor of dilation is 2.

You want to choose the number line graph that appropriately represents the inequality 0 < x ≤ 26.
Graphing inequalitiesThe given compound inequality is conveniently written with the "arrows" pointing to the left. This means the lower limit of the variable is on the left side of the inequality, just as it is on the left end of the number line graph.
The inequality symbols used are "less than" (<) and "less than or equal to" (≤). The "less than" symbol is represented on a number line graph by an open circle. The "less than or equal to" symbol is represented by a filled dot on the number line.
This means you are looking for a graph that has an open circle on the left end of a solid line, and a filled dot on the right end. Only graphs B and C have finite-length lines, and only graph C has a filled dot at the right end.

The National Science Institute was conducting research on the speed of Cheetahs. After
concluding their research, they were able to predict the cheetahs speed or distance when given
certain times or miles that the cheetah traveled. Complete the table of values and graph the
data on the coordinate plane.
Time(min) |. Distance(mi)
0. 0
1/2. 2/3
1. ?
? 3
8. ?
Answer the following questions using the information above.
1.) Is the relationship proportional? Why or why not?
2.) What is the unit rate?
Answers
The table of values is:
Time(min) | Distance(mi)
0 0
1/2 2/3
1 4/3
9/4 3
8 32/3
1) The relationship between Distance and Time is proportional.
2) The unit rate is 4/3 miles
To complete the table, we need to find the missing values of time and distance.
We use the relation between Distance, speed and time ,to find the missing values, which is given by,
Distance = Speed x Time
Given when time = 1/2 minute, the distance = 2/3 miles
Speed = Distance/Time
= 2/3 x 2/1
= 4/3 mile per minute.
This is the constant speed of the cheetah. We use this constant speed to find the other values to complete the table.
So If we take 'y' as the distance and 'x' as the time, then the relationship between time and distance can be expressed as
y = (4/3)x [since Distance = Speed x Time ].
So this relationship is proportional because there is a constant of proportionality 4/3 in the linear equation above and hence can be graphed as well.
The graph will contain the time values on the x-axis and distance values on the y-axis.
So now we need to find the missing values on the table using the above linear equation.
When time, x = 1 minute, distance, y = (4/3) x 1 = 4/3 miles.
When distance, y = 3 miles, 3 = (4/3)x
⇒ time, x = 3 x (3/4) = 9/4 minutes.
When time, x = 8 minutes, distance, y = (4/3) x 8 = 32/3 miles.
So the table is:
Time(min) | Distance(mi)
0 0
1/2 2/3
1 4/3
9/4 3
8 32/3
The unit rate refers to the y-value when the x-value is unity(1). So the unit rate here is found when time = 1 minute.
From the table, distance when time = 1 minute is 4/3 miles.
Hence, unit rate = 4/3 miles.
