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

Answers

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

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.

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.

Answers

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

How do I solve them?

Answers

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

Answers

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% .

Susan can swim 105 meters in 70 seconds. At this rate, how far can she swim in 30 seconds?

Answers

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

The cost, y y , for x x pounds of nails can be represented by the equation y=3.20x y = 3.20 x . What is the constant of proportionality of the equation?

Answers

Answer:

3.20

Step-by-step explanation:

If y is proportional to x as represented as;

y = 3.20x

This means that the relationship between y and x is a direct proportionality

y = kx

k is the constant of proportionality

Comparing with the given equation we will see that k = 3.20

Hence the constant of proportionality is 3.20

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?

Answers

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.
