PLEASEEE PLEASSE HELP!! BRANLIEST!!!PLEASEEE Triangle XYZ is formed by the three squares J, K, and L: Which statement best explains the relationship between the sides of triangle XYZ? XY + YZ = ZX, because 144 + 256 = 400 (XY)2 + (YZ)2 = (ZX)2, because 144 + 256 = 400 (XY)2 + (YZ)2 = (ZX)2, because 202 + 122 = 162 XY + YZ = ZX, because 202 + 122 = 162
Solution 1

Triangle XYZ is formed by the three squares J, K, and L

So it is a right triangle.

Pythagorean Theorem: a^2 + b^2 = c^2


(XY)^2 + (YZ)^2 = (ZX)^2, because 144 + 256 = 400

Solution 2
I would say is the correct answer because of the Pythagorean theorem.
a^2 + b^2 = c^2
XY^2 + YZ^2 = ZX^2
12^2 + 16^2 = 20^2
144 + 256 = 400

My best guess is B.

Hope this helps =)
A barrel of tomato sauce has spilled on a tile floor. The sauce flow can be expressed with the function r(t) = 2t, where t represents time in minutes and r represents how far the sauce is spreading. The spilled sauce is creating a circular pattern on the tile. The area of the pattern can be expressed as A(r) = πr2. Part A: Find the area of the circle of spilled sauce as a function of time, or A[r(t)]. Show your work. (6 points) Part B: How large is the area of spilled sauce after 5 minutes? You may use 3.14 to approximate π in this problem. (4 points)
Solution 1

Part A:
Given in the statement
r(t)= 2t
A(r) = πr2
So to find A[r(t)]
You have to plug r(t) into A(r)
Answer: A[r(t)] =π(2t)2=4πt

Part B:
The statement tells you t=5 min and

So plug in you values
A[r(t)]=π(2(5))2=4* 3.14*5=62.8

Prove that x²+6x+18 is always greater than For any value of x.
Solution 1
One way to solve this would be to graph both y=x^2+6x+18 and y=2 - 1/x.  If the graph of the polynomial is always higher up (above) the graph of y=2-1/x, that alone is sufficient cause to state that the poly is always greater than 2-1/x.

You could also do this algebraically:  write the inequality

x^2+6x+18 > 2 -1/x.  This can be rewritten as x^2+6x+18-2+1/x > 0, or
                                                                         x^2+6x+16+1/x > 0

Try x=-3.  Then 9-18+16-1/3 = 6 2/3, which is greater than 0.

Or you could graph x^2+6x+16+1/x by hand or on a calculator.  Is the graph always above the x-axis?  If so,  x²+6x+18 is always greater than 2-1/x.

The area of a trapezoid is 70.55 square feet. The length of the bases are 11.4 feet and 5.6 feet. What is the height of the trapezoid? 4.15 ft 4.15 ft2 8.3 ft 8.3 ft2
Solution 1

The height of the trapezoid with an area of 70.55 sq feet is, 8.3 feet.

What is a trapezoid?

A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.

The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.

The altitude is the measurement of the angle perpendicular to the parallel sides.

We know, The area of a trapezoid is,

(1/2)×(sum of the two parallel sides)×height.

Therefore, From the given information,

(1/2)×(11.4 + 5.6)×h = 70.55.

(1/2)×(17)×h = 70.55.

17h = 141.1.

h = 8.3 feet.

Solution 2
I got 8.3 ft.
By using the formula for finding the area of a trapezoid

H=8.3 ft
What is the place value of the digit 4 in 6,296.04
Solution 1

The digit 4 is in the hundredths place, since it's behind a decimal.

Place value in front of a decimal goes as:

Ones, tens, hundreds, thousands, etc

Place value behind a decimal goes as:

dankllord Mark simplified three over five divided by five over eight.; his work is shown below. Identify where he made his error. Original division problem: three over five divided by five over eight. Step 1: three over five multiplied by eight over five. Step 2: three times eight over five times five. Step 3: twenty-four over five. Step 4: four and four over five. Step 1 Step 2 Step 3 Step 4
Solution 1


100% Correct

The correct answer is C) Step 3


3 × 8 = 24 and 5 × 5 = 25 not 5

Hope this helps!!!! :)


*If you don't mind... can you please mark me Brainliest. I only need 1. Please!!!! :)

Solution 2
The error is in Step 3.
\dfrac{3}{5} \times \dfrac{8}{5} = \dfrac{3 \times 8}{5 \times 5} = \dfrac{24}{25}  not  \dfrac{24}{5}
You spin a spinner 48 times. Out of the 48 trials, the pointer lands 6 times on section two. What is the experimental probability of the pointer landing on section two? 1/3 1/27 1/8 1/7
Solution 1
The experimental probability would be equal to the number of times the event happened over the number of times it was attempted. In this case, the experiment was tried 48 times, and only 6 times did it land on 2. The experimental probability is 6/48, which simplified to 1/8.

Step-by-step explanation:

Can anyone help what is the answer to 2[3w - 5y]
Solution 1
2 ( 3w-5y )
= 2*3w-2*5y
= 6w-10y

Therefore, the product is 6w-10y
Solution 2
2 times 3w= 6w

2 times 5y= 10y
so the answer is 6w-5y
Maria is ordering copy paper for her office. The office is low on white paper and on blue paper. She will pay $3.50 per realm of white paper and $3.75 per realm of blue paper. If the purchase order is for $36.00 and she ordered 10 realms of paper, how many realms of white paper will she receive
Solution 1
You have:

 x: the number of reams of white paper purchased 
 y:the number of reams of blue paper purchased 

 Then, you have the following system of equations:


 When you solve the system shown above, you obtain:


 The answer is: 6 reams of white paper
Solution 2
Let a =  reams of white pape b =  reams of blue paper

1>>>  a+b=10
2>>> 3.50a+3.75b=36

There will be 6 realms of white paper that Maria will receive
