Match each circular flower bed on the left to its circumference and its area on the right. Some answer options on the right will not be used.
Answer:
Bed A --- Third Option
Bed B --- Fifth Option
Step-by-step explanation:
Flower Bed A)
The formula for circumference is:
[tex]C=2\pi r[/tex]
The diameter of A is 10 feet. So, its radius is 5 feet.
Substitute 5 for r. So, the circumference of Bed A is:
[tex]C=2\pi (5)=10\pi\text{ feet}[/tex]
The formula for the area of a circle is:
[tex]A=\pi r^2[/tex]
Substitute 5 for r:
[tex]A=\pi (5)^2[/tex]
Square and simplify:
[tex]A=25\pi \text{ square feet}[/tex]
So, the circumference of Bed A is 10π feet and its area is 25π square feet.
Therefore, match Bed A to the third option.
Flower Bed B)
The radius of Bed B is 6 feet. Again, we can use the circumference and area formulas. Substitute 6 for r for circumference:
[tex]C=2\pi (6)[/tex]
Multiply:
[tex]C=12\pi\text{ feet}[/tex]
Substitute 6 for r for the area formula:
[tex]A=\pi(6)^2[/tex]
Square and simplify:
[tex]A=36\pi\text{ square feet}[/tex]
So, Bed B has a 12π feet circumference and a 36π square feet area.
Therefore, match Bed B to the fifth option.
And we're done!

The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Josh is comparing the cost of having his car wash plus filling up his tank with gas at each business. How many gallons of gas would he need to purchase for the cost to be the same at each car wash?
Answer:
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash
Step-by-step explanation:
We need to model both car wash's costs. The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. If x is the number of gallons of unleaded gasoline. the total charges of this store are:
C1=15+2.5*x
The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Following the same procedure, their costs are:
C2=10+2.75*x
Josh wants to know how many gallons of gas will make both businesses charge the same. Equating both equations:
15+2.5*x=10+2.75*x
Simplifying:
-0.25x=-5
Solving:
x=-5/(-0.25)=20
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash

Step-by-step explanation:
1. A specialty shop sells gift baskets that contain three different types of
candles: tapers, pillars, and jar candles. Tapers cost $1 each, pillars cost $4
each, and jar candles cost $6 each. Each basket contains 8 candles costing
a total of $24, and the number of tapers is equal to the number of pillars
and jar candles combined. Which system of equations represents the
situation, where t is the number of tapers, p is the number of pillars, and jis
the number of jar candles? *
Answer:
Option (B)
Step-by-step explanation:
Let the number of tapers in the basket = t
Number of pillars = p
And the number of jar candles = j
Tapers cost = $1 each
Jar candles cost = $6 each
Pillars cost = $ 4
Total number of candles in the basket = 8
Therefore, equation will be,
p + t + j = 8 -----(1)
Cost of the candles in the basket = $24
$1t + $4p + $6j = $24
t + 4p + 6j = 24 -------(2)
Since number of tapers is equal to the number of pillars and jar candles combined,
t = p + j
t - p - j = 0 ------(3)
Therefore, Option (B) is the answer.

Fun Zone charges an entrance fee
of $4.50 and $0.65 per ticket. Happy
Town charges $0.40 per ticket and a
$5.00 entrance fee. How many
tickets must be purchased in order
for the total to be the same at both
Fun Zone and Happy Town?
Answer:
2 tickets
Step-by-step explanation:
To be the same they must equal each other.
4.50 + 0.65x = 0.40x + 5
isolate the variable
subtract 4.50 from both sides
0.65x = 0.40x + 0.50
subtract 0.40x from both sides
0.25x = 0.50
divide both sides by 0.25
x = 0.50 ÷ 0.25
x = 2

The graph shows a proportional relationship because it is a line, and the difference between each point is the same.
The graph shows a proportional relationship because it is a line, and each x-value is a multiple of 2.
The graph does not show a proportional relationship because each point written as a ratio gives a different value.
The graph does not show a proportional relationship because a line that increases by 1 in the y-value cannot have a
constant of proportionality.
I think but it can also be the first one
The graph shows a proportional relationship because it is a line, and each x-value is a multiple of 2.
Answer: it may be C
Step-by-step explanation:
The graph does not show a proportional relationship because the line does not go through the origin.

What is the slope for (-3,7) and (9,-14)
Answer:
-7/4
Step-by-step explanation:
The slope of the line is -7/4
Answer:
= -7/4
Step-by-step explanation:
When we have 2 points, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -14-7)/(9- -3)
= ( -14-7)/(9+3)
= -21/12
Simplify
= -7/4

Maggie's brother is 6 years younger than four times her age. The sum of their ages is 69.
How old is Maggie?
Answer:
15
Step-by-step explanation:
If Maggies age is, for example, x, we can say that her brothers age is 4x-6. We know from the problem that Maggies age (x) plus her bothers age, (4x-6) is 69. So,
4x-6+x=69
5x-6=69
5x=75
x=15
So, Maggie is 15.
Answer: Maggie is 15 years old
Step-by-step explanation:
69 = (4m - 6) + m --- get an equation
69 - m = 4m - 6 --- lets subtract m from both sides first
75 - m = 4m --- add 6 on both sides
75 = 5m --- add m on both sides
15 = m --- divide by 5 on both sides
m = 15, so Maggie is 15 years old
Let's check:
69 = (4(15)-6) +15
69 = (60 - 6) + 15
69 = 54 + 15
69 = 69
