If Derek swims 5 laps in 1/4 of an hour, he swims 4 times of 5 laps in an hour. This is because 4 times 1/4 is one, or an hour. 5 times 4 is 20.
What is x? Round your answer to the nearest thousandth.
Answer:
[tex]x=10[/tex]
Step-by-step explanation:
We can utilize the Triangle Propotionality Theoerm.
Therefore, we acquire that:
[tex]\displaystyle \frac{14}{x-3}=\frac{16}{x-2}[/tex]
Solve for x. Cross-multiply:
[tex]16(x-3)=14(x-2)[/tex]
We can first divide everything by 2:
[tex]8(x-3)=7(x-2)[/tex]
Distribute:
[tex]8x-24=7x-14[/tex]
Add 24 to both sides:
[tex]8x=7x+10[/tex]
Subtract 7x from both sides. Therefore, the value of x is:
[tex]x=10[/tex]

[tex]x = 27.2 \text{ cm}\\\\x = 27.2 \text{ cm} * \frac{1 \text{ inch}}{2.54 \text{ cm}}\\\\x = \frac{27.2}{2.54} \text{ inch}\\\\x \approx 10.7086614 \text{ inches}\\\\x \approx 10.7 \text{ inches}\\\\[/tex]
Effectively all we do is divide 27.2 over 2.54 to convert from cm to inches.
This means that 27.2 cm is roughly the same as 10.7 inches.
I rounded to one decimal place because 27.2 is to one decimal place. If your teacher says for you to round otherwise, then follow those instructions of course.

After a dilation centered at the origin, the image of CD is C'D'.
If the coordinates of the endpoints of these segments are C(6,-4),
D(2,-8), C'(9,-6), and D'(3.-12), the scale factor of the dilation is
3/2
2/3
3
1/3
Answer: 3/2
Step-by-step explanation: just believe me
The value of the dilation factor is 3/2 after a dilation centered at the origin, and the image of the CD is C'D' option first is correct.
What is dilation?The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.
We have CD after dilated from centered it becomes C'D'
Let m be the dilation factor:
Then,
6m = 9 ⇒ m = 3/2
-4m - -6 ⇒ m = 3/2
2m = 3 ⇒ m = 3/2
-8m = -12 ⇒ m = 3/2
Thus, the value of the dilation factor is 3/2 after a dilation centered at the origin, and the image of the CD is C'D'. If the coordinates of the endpoints of these segments are C(6,-4), D(2,-8), C'(9,-6), and D'(3.-12)

The legs of a right triangle measure 8 cm and 6 cm respectively. How long is the longest side of the triangle?
a.12
b.10
c.14
d.11
Answer:
b. 10
Step-by-step explanation:
Based on the Pythagoras Theorem, the longest side of a right-angled triangle is: [tex]\sqrt{a^{2}+b^{2} }[/tex] where a and b are the legs of the triangle.
Longest side of triangle = [tex]\sqrt{8^{2}+6^{2}}[/tex]
= [tex]\sqrt{64+36}[/tex]
= [tex]\sqrt{100}[/tex]
= 10
In 200920092009, Usain Bolt set the world record for sprinting 100 \text{ m}100 m100, start text, space, m, end text in approximately 9\dfrac359 5 3 9, start fraction, 3, divided by, 5, end fraction seconds
Answer:
Average speed = 10.41 m/s
Step-by-step explanation:
It is given that, in 2009, Usain Bolt set the world record for sprinting 100 m on 9 3/5 seconds.
It can be assumed to find her average speed. Speed is equal to total distance covered divided by total time taken.
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{100\ m}{9\dfrac{3}{5}\ s}\\\\=\dfrac{100}{\dfrac{48}{5}}\ m/s\\\\=\dfrac{500}{48}\ m/s\\\\=10.41\ m/s[/tex]
So, the average speed of Usain Bolt is 10.41 m/s.

Select the correct answer. What is the standard form of this complex number?
Answer:
C
Step-by-step explanation:
Given
3i + ([tex]\frac{3}{4}[/tex] + 2i) - (3 + 3i) ← distribute both parenthesis
= 3i + [tex]\frac{3}{4}[/tex] + 2i - 3 - 3i ← collect like terms
= - [tex]\frac{9}{4}[/tex] + 2i → C
The sides of two similar trapezoids are in a ratio of 1:3. The area of the smaller trapezoid is 12 squared inches. Find the area of the larger trapezoid
Answer:
108 sq in.
Step-by-step explanation:
The ratio of the areas is the square of the ratio of the sides.
Side ratio 1:3
Area ratio 1:9
The side of the larger trapezoid is 3 times the side of the smaller trapezoid.
The area of the larger trapezoid is 9 times the area of the smaller trapezoid.
9 * 12 sq in. = 108 sq in.

A company produces 7,200 gallons of bottled water each day. The company puts 8 one-gallon bottles in each carton. How many cartons are needed to hold all the one-gallon bottles produced in one day? I think the answer is 900 because 8x9 is 72 and if you add two zeros to the nine its 900 hundred then you add the two zeros from the nine and get 72,000 so this is why i think the answer is 900 *-*
Answer:
900 cartons
Step-by-step explanation:
A company produces 7,200 gallons of bottled water each day.The company puts 8 one-gallon hoteles in each cartón.How many cartons are needed to hold all the one-gallon bottles produced in one day
Total gallons of water produced by the company each day = 7,200 gallons gallons bottles
Gallons of water in each carton = 8 one-gallon bottles
How many cartons are needed to hold all the one-gallon hoteles producen in one day
= Total gallons of water produced by the company each day / Gallons of water in each carton
= 7,200 / 8
= 900 cartons
900 cartons are needed to hold all the one-gallon bottles produced in one day

Hillary needs a few new items for the start of softball season. She found some great sales! Help her find out the price she will pay for each item. 1. $50 softball glove, 30% off 2. $50 softball bat, 60% off 3. $50 cleats, 20% off
Answer:Hillary will pay $35.00 for softball glove, $20.00 for soft ball bat and $40.00 for cleats
Step-by-step explanation:
Step 1
A percentage off of a price of an item is the amount that can be saved from purchasing that item, it can also be referred as a discount given on an item purchase.
Step 2 --- Calculation
Actual Price of Softball glove= $50
Discount= 50 x 30/100 = $15.00
Price to pay= $50 - $15.00 = $35.00
Actual Price of soft ball bat= $50
Discount= 50 x 60/100 = $30.00
Price to pay= $50 - $30.00 = $20.00
Actual Price of cleats= $50
Discount= 50 x 20/100 = $10.00
Price to pay= $50 - $10.00 = $40.00
Therefore, Hillary will pay $35.00 for softball glove, $20.00 for soft ball bat and $40.00 for cleats
