PLEASE HELP RIGHT NOW! 15pts Square RSTU is constructed with line PQ drawn through its center. If the square is dilated using a scale factor of one over two(1/2) and a line is drawn through the center of the new dilated figure, what relationship will the new line have with line PQ? Explain your reasoning using complete sentences.
Answers
The line PQ will also dilate using a scale factor of 1/2 and length becomes PQ/2.
What is dilation?Dilation is the process of increasing an object's size without altering its shape. Depending on the scale factor, the object's size may increase or shrink. A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's shape doesn't change.
Given that,
A square is RSTU.
Also, a line PQ drawn through the center.
When the square is dilated using a scale factor of 1/2,
The line that is drawn through the center will also be dilated.
Hence, the line PQ will be dilated by 1/2,
And the length of line will be PQ/2.

Answers
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

For your party you purchased balloons for $.79 each. You spent a total of $11.85. About how many balloons were purchased?
Answers
Let us suppose the number of balloons purchased is x in number.
It is given balloons are purchased for $.79 each
Cost of x balloons = .79x.
Total amount spent on purchasing balloons = $11.85
Cost of x balloons = Total cost of balloons.
.79x=11.85
With x .79 is multiplied .Opposite of multiplication is division.
We perform the opposite operation both sides
Dividing both sides by .79
x=11.85÷.79
x=15
Total number of balloons purchased is 15.

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
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.
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

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
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
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
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.

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

Lucy has a strawberry lace that is 36cm long. She needs pieces 18mm long to decorate a cake. How long is the 36cm one in mm
Answers
36 cms = 360 mm
(Because we multiply by 10, when we convert from cm to mm).
Given Lucy has a strawberry lace that is 36cm long.
The question is asking to convert 36 cm to mm.
1 centimeter is equal to 10 millimeters: 1 cm = 10 mm.
The distance 36 in millimeters (mm) is equal to the distance 36 in centimeters (cm) times 10
36 cm = 36x 10=360 mm
36 cm converted to mm is 360 mm.
The strawberry lace that is 36cm long in mm is equal to 360 mm.

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.
