Complete Question:
Find the coordinates of the point after the described reflection. Give the distance between the point and its reflection. R(-5, 8) is reflected across the x-axis _____________.
Answer:
[tex](a)[/tex] [tex]R' = (-5,-8)[/tex]
[tex](b)[/tex] The distance is 16 units
Step-by-step explanation:
Given
[tex]R = (-5,8)[/tex]
Solving (a): Reflection across x-axis
The rule is:
[tex]R(x,y) ==> R(x,-y)[/tex]
So, the reflection of [tex]R = (-5,8)[/tex] is:
[tex]R' = (-5,-8)[/tex]
Solving (b): The distance between R and R'
Distance (d) is calculated as:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
Where:
[tex]R = (-5,8)[/tex] ---- [tex](x_1,y_1)[/tex]
[tex]R' = (-5,-8)[/tex] --- [tex](x_2,y_2)[/tex]
This gives:
[tex]d = \sqrt{(-5- -5)^2 + (-8- 8)^2}[/tex]
[tex]d = \sqrt{(0)^2 + (-16)^2}[/tex]
[tex]d = \sqrt{256}[/tex]
[tex]d = 16[/tex]
The distance is 16 units

mr. torres ordering 250 School t-shirts to sell in a school store the t-shirts come in blue gray or red to know how many of each color to order mr. torres polled a random sample of students l.the results are in the table
Answer:17
Step-by-step explanation:
so i think it would be 17 as 5 is equivlent to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since i think ur school rounds that percentage it would 17 red shirts
The results are in the table of the 250 total T-shirts about should be red 17.

Mr. torres ordered 250 School t-shirts to sell in a school store the t-shirts come in blue-gray or red to know how many of each color to order Mr. Torres polled a random sample of students. the results are in the table.
What is the random sample?
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
So I think it would be 17 as 5 is equivalent to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since I think your school grounds that percentage it would be 17 red shirts.

juan drove 126 miles in 3 hours. If he continued at the same rate, how long would it take to travel 336 miles?
Answer:
8 hours
Step-by-step explanation:
First you divide 126 by 3 to get the Miles Per Hour, you should get 42 Miles Per Hour, then, just divide 336 by 42 to get the numbers of hours he will have to drive, (which is 8)
Answer:
8 hours
Step-by-step explanation:
126 miles - 3 hours
336 miles - x hours
Cross multiply
126x = 336 x 3
126x = 1008
Divide both sides by 126
x = 1008/126
x = 8
Round 27.2847 to the nearest a. tenth and b. hundredth. SHOW YOUR WORK AND NO LINKS PLEASE, THANK YOU!
Answer:
A. 27.3
B. 27.28
Step-by-step explanation:
You would have to round the tenth place up because of the 8 in the hundredths place, and for the hundredth place you would have to see if the thousandths place is higher than a 5 and if not don’t round up.
Answer:
a=27.3000
b=27.2800
Step-by-step explanation:
you just look at the decimal places and ignore the whole numbers for now the you look at the 2 since it is tenth the number at its back will add one to it because 8 is greater than 5 and it becomes 3 since we added 1 to 2 . our number then becomes 27.3 and the zeros you can remove them or put them it doesn't matter.

ABC and is a straight line
Work out the length of AC
Give your answer to 1 decimal place
Answer:
19.2
Step-by-step explanation:
I hope it helps you.....
Answer:
AC ≈ 19.2 cm
Step-by-step explanation:
Using Pythagoras' identity in Δ BCD to find BC
BC² + BD² = DC² , that is
BC² + 12.6² = 19.3²
BC² + 158.76 = 372.49 ( subtract 158.76 from both sides )
BC² = 213.73 ( take the square root of both sides )
BC = [tex]\sqrt{213.73}[/tex] ≈ 14.62
Using the tangent ratio in Δ ABD to find AB
tan20° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{BD}[/tex] = [tex]\frac{AB}{12.6}[/tex] ( multiply both sides by 12.6 )
12.6 × tan20° = AB , then
AB ≈ 4.59
Then
AC = AB + BC = 14.62 + 4.59 ≈ 19.2 cm ( to 1 dec. place )
A school band went on a trip to a music festival. The band director was admitted for free, but it cost $100 to rent a bus for the trip and $4 for each student to get into the festival. The total cost of the trip was $244. Which equation can be used to find s, the number of students that went on the trip?
Answer:
100 + 4s = 244
Step-by-step explanation:
Cost of the ticket for s students = 4s
Bus rent + cost of ticket for 's' students = $ 244
100 + 4s = 244

A fish tank in the shape of a rectangular prism holds 30 cubic feet of water .the tank has a length of 5 feet and width of 3 feet . What is the length in depth,in feet ,of the tank ? A-2
B-6
C-10
D-15
Answer:
A - 2 feet
Step-by-step explanation:
We know that the tank is a rectangular prism which means the volume is equal to length*width*depth
since the tank can hold 30 cubic feet of water, we can divide 30 by the given dimensions of the length and width to find the depth
30/5 = 6
6/3 = 2
therefore, the depth of the tank has to be 2 feet (A)
Length x Width x Depth
From the question:
Volume of the rectangular prism = 30 cubic feet
Length of the rectangular prism = 5 feet
Width of the rectangular prism = 3 feet
Depth of the rectangular prism = ?
The formula to find the Depth of the rectangular prism is :Depth = Volume / (Length x Width)
Hence,
Depth = 30 cubic feet / 5 feet x 3 feet
Depth = 30/ 15
Depth = 2 feet
The correct option is option A
