A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people prefer eating out?
Answer:
400 people
Step-by-step explanation:
15 = 12
500 = x
Cross multiply
15x = 12 × 500
Divide both sides by 15
[tex]\frac{15x}{15}[/tex] = [tex]\frac{12 * 500}{15}[/tex] (* means multiplication if you do not know)
[tex]\frac{12 * 500}{15}[/tex] = 100 × 4= 400 people

Which figure correctly demonstrates using a straight line to determine that the graphed equation is not a function of x? HELP PLZZZZZZZZZZZZZZZZZZZZZZZZZZ the question is at the top and the choices are the attachments THX SO MUCH TO WHO EVER FIGURES THIS OUT.
Answer:
Lower left.
Step-by-step explanation:
To determine if a graph is a function the "vertical line test is used. If any point on a graph has one x value go to two y values it is not a function.
Witht he four pictures, the two on the right use a horizontal line, so it doesn't tell at all, on the leftthe upper one is vertical but it doesn't show that one x value has two corresponding y values. So it must be the lower left one.
The lower left picture has a line at x=1, and it passes through the line of the graph at two different y values, 4 and -4. So this has two y values with one x value.
Answer:
I believe the graph with the line going through 1,0 (x,y) is correct because it doesnt pass the vertical line test
Step-by-step explanation:
What should be the first step to solve the equation? 2x + 9(x – 1) = 8(2x + 2) – 5 Combine like terms on each side of the equation. Use the distributive property on each side of the equation. Use the subtraction property of equality to subtract 5 from each side of the equation. Use the addition property of equality to add 2x to each side of the equation.
Answer: The answer is B, use the distributive property on each side of the equation.
A hot air balloon rose from ground level to 1000 feet in order to pass over a mountain. The balloon then descended
800 feet to a cruising height.
Which point is a representation of cruising height in feet?
Point A
Point B
Point C
Point D
200ft.
Step-by-step explanation:
It's 200ft because you just do 1000 - 800 = 200ft
Point C represent the cruising height.
What is number line?when we represent the numbers on a line the numbers can be positive negative or any type are done on number line zero is the center of the number line.
Given that air balloon height is 1000 feet from ground
and descended to 800 feet
present height of air balloon is 1000 - 800 = 200 feet
Hence according to no. line in figure 200 feet lie in point C

Tonya plans to join a fitness club. She researched the costs to join different clubs in her area and found that there is a linear relationship between the total cost of belonging to a club and the number of months that you are a member. Each club charges monthly dues, and some clubs require new members to also pay a one-time membership fee. The total costs of being a member for 6 months, 12 months, and 24 months at each of three clubs are shown in the table.
Total Cost of Fitness Club Membership
Length of membership
Club 1
Club 2
Club 3
6 months
$108
$120
$126
12 months
$216
$210
$252
24 months
$432
$390
$504
How many of the clubs require new members to pay a one-time membership fee?
A: 0
B: 1
C: 2
D: 3
The number of clubs that require new members to pay a one-time fee is one.
In order to determine which fitness club requires a one-time membership fee, the average cost per month for each club has to be determined.
Cost of membership per month = cost / number of months
Average cost of Club 1
Average cost for 6 months = $108/6 = $18
Average cost for 12 months = $216 / 12 = $18
Average cost for 24 months = $432 / 24 = $18
The average costs each month is the same. This means that there is no one-time membership fee in this club.
Average cost of Club 2
Average cost for 6 months = 120 / 6 = $20
Average cost for 12 months = $210 / 12 = $17.50
Average cost for 24 months = $390 / 24 = $16.25
The average costs each month is not the same. This means that there is a one-time membership fee in this club.
Average cost of Club 3
Average cost for 6 months = $126 / 6 = $21
Average cost for 12 months = $252 / 12 = $21
Average cost for 24 months = $504 / 24 = $21
The average costs each month is the same. This means that there is no one-time membership fee in this club.

Maria had 4 full cement, blocks & one that was 5/9 the normal size, If each full block weight 3 8/9 pounds, What is the Weight blocks maria has? (20 POINTS!)
The total Weight blocks maria has is 15.2 pounds.
What is Fraction?A fraction represents a part of a whole.
Given that Maria had 4 full cement, blocks & one that was 5/9 the normal size.
Each full block weight [tex]3\frac{8}{9}[/tex] pounds
We need to find the Weight blocks maria has
Let us convert the mixed faction to improper fraction
35/9 = [tex]3\frac{8}{9}[/tex]
As there are 4 full cement, blocks
So multiply 4 with [tex]3\frac{8}{9}[/tex]
4×35/9
4×3.8
15.2
Hence, the total Weight blocks maria has is 15.2 pounds.
