Fiona has a rectangular garden where the length to width ratio is 3:2.She has 54ft^2 of plants in her garden.Fencing is in sale for $2.50 per foot .How much will she spend to put a fence around her garden
Answer: $75.0
Step-by-step explanation:
Based on the above figures given in the question, the length of the rectangular garden will be 9feet and the width will be 6feet
Length = 9feet.
Width = 6feet
Perimeter = 2 (length + breadth).
= 2(9feet + 6feet)
= 2 (15feet)
= 30 feet
Since fencing is in sale for $2.50 per foot, the amount that she will spend to put a fence around her garden will be:
= $2.50 × 30
= $75.0
A supermarket has bags of red grapes for 22.96 for 7 bags
They also had bags of green grapes priced 9.60 for 3 bags
Which type was most expensive?
Answer:
The bag of red grapes costs more.
Step-by-step explanation:
We can do proportions.
A supermarket has bags of red grapes for 22.96 for 7 bags:
[tex] \frac{22.96 \: dollars}{7 \: bags} = \frac{x}{1 \: bag} \\ \frac{7x}{7 } = \frac{22.96}{7} \\ x = 3.28[/tex]
For one bag of red grapes, its costs $3.28.
They also had bags of green grapes priced 9.60 for 3 bags:
[tex] \frac{9.60 \: dollars}{3 \: bags} = \frac{x}{1} \\ \frac{3x}{3} = \frac{9.60}{3} \\ x = 3.2 \: \: \: - > 3.20[/tex]
One bag of green grapes costs $3.20.
The bag of red grapes costs more.

Answer:
The slopes of WX and XZ
Step-by-step explanation:
The singular factor that determines if the parallelogram is a rectangle are the angles at the edges
Mathematically, we can only have a rectangle if there are four right angles with one right angle each at the edges of the rectangle
So, by having the slope of the sides forming the width and that which forms the length, we can deduce if what we have is rectangle given that the slopes will yield a perpendicular product
Hence, the slopes of WX and XZ can be calculated to show this

Ida needs to hire a singer for her wedding. Singer A is offering his services for an initial $95 in addition to $12.95 per hour. Singer B is offering her services for an initial $99 in addition to $11.85 per hour. When will the two singers charge the same amount of money? If necessary, round your answer to the nearest tenth.
Answer:
The answer is 3.6
Step-by-step explanation:
Step one:
Singer A is offering his services for an initial $95 in addition to $12.95 per hour
let the number of hours be x and the total charge be y
the expression for the total for singer A is
y=12.95x+95----------2
Singer B is offering her services for an initial $99 in addition to $11.85 per hour
let the number of hours be x and the total charge be y
the expression for the total for singer A is
y=11.85x+99----------2
Step two:
Equating 1 and 2 we have
12.95x+95=11.85x+99
collect liker terms
12.95x-11.85x=99-95
1.1x=4
divide both sides by 1.1
x= 4/1.1
x=3.63
to the nearest tenth it is 3.6

Answer:
Step-by-step explanation:
(a) Since values 5 or up go up and 4.9 and under go down, Naomi could have gone 4555 to 4564.9, as 4555 rounds up to 4560 (and is the largest number that does so) and vice versa for 4564.9
Similarly, Peta could have went from 4550 to 4649.9.
(b)
Peta could have walked 4550 and Naomi 4564.9, so this could be true
Peta could have walked 4649.9 and Naomi 4555, so this could be true
Peta could have walked 4555 and Naomi 4555, so this could be true.
All values here are in the ranges of (a)

Susan can swim 105 meters in 70 seconds. At this rate, how far can she swim in 30 seconds?
Answer:
45 meters per 30 seconds
Step-by-step explanation:
To figure this question out you first gave to find the unit rate of meters per second by dividing 105 by 70.
105 divided by 70 = 1.5
So Susan can swim 1.5 meters per second.
Then we multiply that amount by 30 to find the number of meters she can swim in 30 seconds.
1.5 x 30 = 45 meters
So, in conclusion, Susan can swim 45 meters per 30 seconds
Madelyn has completed 10/20 problems. Will has completed 80% of the problems. Adam has finished 3/4 of them. Who has finished the most
Answer:
Will has completed the Most.

Madelyn has completed 50%
Adam has completed 75%
Will has completed 80%
I hope this helps!!! Please Mark Me Brainliest!!!!!!
Answer: Will
Step-by-step explanation:
Madelyn = 50%. 10/20 = 50%, because 10/20 is half, and 50% is half
Will = 80%
Adam = 75%. 3/4 x 25 = 75/100, which equals 75%.
So in conclusion, Will has finished the most problems, 2nd is Adam, and last is Madelyn.

In a survey of 3300 people who owned a certain type of car, 1320 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer: The percent of the people surveyed were satisfied with the car = 40% .
Step-by-step explanation:
Given: Total number of people surveyed = 3300
Number of people said that they would buy that type of car again = 1320
i.e. Number of people were satisfied with the car = 1320
The percent of the people surveyed were satisfied with the car =
[tex]=\dfrac{1320}{3300}\times100\\\\=\dfrac{12}{30}\times100\\\\=\dfrac{4}{10}\times100\\\\=0.4\times100=40\%[/tex]
Hence, the percent of the people surveyed were satisfied with the car = 40% .
a number c minus 4.3 is no less than 16. write this word sentence as an inequality.
ill give brainliest
Answer:
c - 4.3 > 16
(hope this helps)
The inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.
What is inequality?The relationship between two values that are not equal is described by inequalities. Equal does not necessarily mean unequal. The "not equal symbol" is typically used to denote that two values are not equal.
As the condition is suggesting c - 4.3 is no less than 16 means it is greater than 16,
So, c - 4.3 > 16
Therefore, the inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.

Someone please explain, it's most of my homework! I already did half the problem! Ellie bought 5 cups of apple juice and 7 sandwiches for $25.00. Jim bought 2 cups of apple juice and 3 sandwiches for $10.50. How much did each cup of apple juice cost? How much did each sandwich cost. I set up the equations 5a+7s=25 and 2a+3s=10.5. How do I solve them?
Answer:
5 cups of apple juice and 7 sandwiches for a total of 25 bucks Jim bought 2 cups of apple juice and 3 sandwiches for $10.50Now we must form some sort of equation for the following: (1) 5a+7s=25(2) 2a +3s =10.5Let us isolate for one variable 3s= 10.5-2a s= 3.5 -2/3a Plug that into (1)5a + 7 (3.5 -2/3a) = 25 a=1.5 Hence each apple juice cost 1.5 Now we can plug that into (2) to solve for the sandwich costs= 3.5- 2/3(1.5) s=2.5 Rate positively and give brainlist
