Mr. Nelson is buying property in the shape of a triangle to build a new house. If the property costs $42.50 per square foot, how much will he pay?

Answers

First, you find the area of the figure. Use the formula a=h(b/2)

a=h(b/2)
a=47(98/2)
a=47(49)
a=2303

Now, you multiply that by $42.50 to find out how much he will pay.

2,303x42.50=97,877.50.

He will pay $97,877.50.

To find the area of a triangle, multiply the base by the height and divide by 2.
The figure shows a base of 98 ft and a height of 47 ft.

[tex] A = \dfrac{bh}{2} [/tex]

[tex] A = \dfrac{98~ft \times 47~ft}{2} [/tex]

[tex] A = 2,303 ~ft^2 [/tex]

Now that we know the area, we multiply it by the cost of the land per square foot.

2,303 ft^2 * $42.50/ft^2 = $97,877.50

He must pay $97,877.50

Please Be Sure Answer is 100% CORRECT!

Answers

I have these same questions but the way i solved them i did

A: 1/3 x 3.14 x 2*2 x 8 = 32/3 = 2000 divided by 32 = 63 scoops
The formula is 1/3 x 3.14 x r*2 x h
B: 1/3 x 3.14 x 8*2 x 8 = 128/3 = 2000 divided by 128 = 16 scoops

Figure TUVW is transformed to T’U’V’W’, as shown:

Which of the following sequences of transformations is used to obtain figure T’U’V’W’ from TUVW?

Reflection about the y-axis followed by a translation left by 2 units
Reflection about the x-axis followed by a translation left by 2 units
Counterclockwise rotation by 90 degrees about the origin followed by a translation right by 2 units
Counterclockwise rotation by 90 degrees about the origin followed by a translation left by 2 units

Answers

The first sequence of transformation.
If you look closely, the reflection was made from the y-axis. The reflection would be above or below the x-axis if the reflection was to be made through the x-axis.
Also, the figure was moved 2 units to the left. Hence the reflection was moved 2 units from where the reflection should originally be which was (-6,-4).

Hope this answer is helpful.

The correct answer is Reflection across the y-axis and then Translation 2 units to the left. In a translation, the sign on the x of every point is changed. The reflected image is too far to the left to be just a reflection or even a rotation. That is why I said it was translated 2 units

Aiden needs 15 liters of cleaning solution. He can buy a 2-gallon jug ($4.28) a 3 gallon jug ($5.92) a 4 gallon jug ($6.56) a 7 gallon jug ($12.98). Which jug should he purchase to get at least 15 liters of cleaning solution and spend the least amount of money?

Answers

We need 15 liters
2 gallon jug 4.28*2=8.56 1 gallon=3.78, 2 gallons=7.57 liters

3 gallon jug 5.92*3=17.76 3 gallons=11.35 liters

4 gallon jug 6.56*4=26.24 4 gallons=15.14 liters

the best solution is to buy 2 times the 2 gallon jug because he will spent
8.56*2=17.12 for 4 gallons(aprox 15 liters)
instead of the 4 gallon jug which costs 26.24

7 gallon this is more expensive and he does not that much solution

Aiden should purchase a 4-gallon jug ($6.56) to get at least 15 liters of cleaning solution and spend the least amount of money.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that:

Aiden needs 15 liters of cleaning solution.

He can buy a 2-gallon jug ($4.28) a 3-gallon jug ($5.92) a 4-gallon jug ($6.56) a 7-gallon jug ($12.98).

As we know,

1 gallon = 4.54 liters

2 gallon = 9.09 liters

3 gallon = 13.63 liters

4 gallon = 18.18 liters

7 gallon = 31.82 liters

Thus, Aiden should purchase a 4-gallon jug ($6.56) to get at least 15 liters of cleaning solution and spend the least amount of money.

In a survey of 398 students, 52% said they loved music. Use estimation to explain how many students loved music. PLZ HELP I HAVE THIS FOR HOMEWORK RIGHT NOW AND I NEED TO FINISH IT!!!!!

Answers

52 percent of 398 is 206.96 that's the answer

We have 398 students with 52% that love music. To find the percentage for this problem, we can use this equation.
S= total number of students in the survey
M= music lovers
S• (52/100)=M
We have to divide the percentage by 100 because that allows use to calculate under 1, so there isn’t an increase in anyway, it should be less than the initial number. So if we multiply 398 by 52, we would get more than 100 percent, using 1 as 100 for percentages allow for an increase or decrease.
398•.52=206.96
For estimation, we can say there are about 400 students and we have to find 50%. Half of 400 is 200, which is a close estimate. So around 200 students in the school share a love of music.

A parachutist's speed during a free fall reaches 207 kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 20 seconds of free fall? Do not round your answers.

Answers

The speed is 57.5 m/s and the parachutist will fall 1150 m in 20 seconds.

Explanation:
We start out with the ratio 207 km/1 hr.

We know that 1 km = 1000 m; this means 207 km = 207*1000 = 207000 m. This gives us 207000 m/1 hr.

We know that 1 hr = 60 minutes, so we have 207000 m/60 min.

We also know that 1 min = 60 seconds, so 60 min = 60*60 = 3600 sec; this gives us 207000 m/3600 sec.

Dividing this, we get 57.5 m/s.

In 20 seconds, the parachutist will fall 57.5(20) = 1150 m.

Answer:

1150 meters

Step-by-step explanation:

Speed of parachute = 207 kilometers per hour

Speed of parachute in meter /second = (207 x 1000)/ (60 x 60)

= 57.5 meter /second

Parachute fall for 20 seconds with a speed of 57.5 meter /second, Thus the distance covered in 20 seconds

= 57.5 meter /second x 20 seconds

= 1150 meters.

Last week, you finished Level 2 of a video game in 32 minutes. Today, you finished Level 2 in 28 minutes. What is your percent of change?

Answers

The first step to solve this problem is to compute how much change in minutes were you able to have today compared to the last week.

32 minutes – 28 minutes = 4 minutes faster than last week

To compute the percent of change you have to divide the change in minutes to the duration in minutes for the last week:

4 minutes / 32 minutes = 0.125 or 12.5% faster than last week

The original price of an item is $130. The item is on a discount of 1/5 off the original price. You then pay a sales tax of 10%. What is the amount you paid for the item?

Answers

Hello!

First, find 1/5 of $130, and then subtract that from the original price of the item, because it is a discount.

Divide the price of the item by 5.

130 ÷ 5 = 26

130 - 26 = 104

So, the price of the item (not including tax) is $104. Now, we must calculate the sales tax and then add that onto the price of the item, as tax is money collected by the government.

To calculate the tax, multiply the discounted price of the item by the percentage of tax, and then add it.

104 × 10% = 10.4

104 + 10.4 = 114.4

ANSWER:

The amount of money you paid fot the item is $114.4.

the ratio of the areas of two similar polygons is 81:64. If the perimeter of the first polygon is 32 cm, what is the perimeter of the second polygon? Round to the nearest tenth

Answers

In two similar polygons, the ratio of their areas is the square of the ratio of their sides. If the sides of any polygon are a and b then :

Ratio of area =[tex] a^{2} :b^{2} [/tex]

Given ratio of area =81:64

Or 81:64=[tex] a^{2} :b^{2} [/tex]

Taking root of both sides

9:8=a:b

The ratio of perimeter of any two similar polygon is equal to the ratio of sides.

Ratio of perimeter = a:b

Perimeter of first polygon is 32 cm.

Let the perimeter of second polygon be x.

32:x=a:b

Or, 32:x=9:8

[tex] \frac{32}{x} =\frac{9}{8}
[/tex]

Cross multiplying

9x= (32)(8)

9x=256

Dividing both sides by 9

x=28.4.

The perimeter of second polygon is 28.4cm.

A = 3.14 × 64

A = 200.96
