Answer:
x = 2
y = 15
Step-by-step explanation:
As the triangle is split with a line that is parallel to the base:
[tex]\implies x:6=6:18[/tex]
[tex]\implies \dfrac{x}{6}=\dfrac{6}{18}[/tex]
[tex]\implies x=\dfrac{6\cdot 6}{18}[/tex]
[tex]\implies x=\dfrac{36}{18}[/tex]
[tex]\implies x=2[/tex]
Similarly:
[tex]\implies y:20=6 : (6+x)[/tex]
[tex]\implies y:20=6:8[/tex]
[tex]\implies \dfrac{y}{20}=\dfrac68[/tex]
[tex]\implies y=\dfrac{6 \cdot 20}{8}[/tex]
[tex]\implies y=\dfrac{120}{8}[/tex]
[tex]\implies y=15[/tex]
Answer:
x= 5.18
y= 16.97
Step-by-step explanation:
Solve Y first-
trigonometric theorems-
[tex]c^2 =a^2 + b^2\\\\b^2 =c^2 - a^2[/tex]
[tex]y^2 =18^2-6^2 \\y^2 =324 - 36\\y^2= 288\\\sqrt{2} = \sqrt{288} \\ y=16.97[/tex]
solve x-
20-16.97=3.03
x=5.18
(I'm not sure if the answers are correct. I tried my best. I was confused to solve x though. )

Which statement describes the solutions of this equation?
Answers
Answer:
C. The equation has two valid solutions
Step-by-step explanation:
A rational equation like this is often solved by "cross-multiplying" to eliminate the fractions. When we do that, we get ...
4(2x+10) = x(3x+1) . . . . . . . multiply both sides by (3x+1)(2x+10)
3x² -7x -40 = 0 . . . . . . . . . . rearrange to standard form
3x² -15x +8x -40 = 0 . . . . . . separate -7 into factors of 3(-40)
3x(x -5) +8(x -5) = 0 . . . . . factor pairs of terms
(3x +8)(x -5) = 0 . . . . . . . finish factoring
The zeros of these factors are not zeros of the original denominators, so neither of the solutions these give is extraneous.
3x +8 = 0 ⇒ x = -8/3
x -5 = 0 ⇒ x = 5

Mrs. Chang's class built a platform for use in a school play. What is the
volume of the platform?
PLEASE HELP!
Answers
Answer:
Total Platform = 128 ft^3
Step-by-step explanation:
Volume = Length * Width * Height
Left Volume: 2 ft * 4 ft * 3 ft = 24 ft^3
Mid Volume: 4 ft * 4 ft * 5 ft = 80 ft^3
Right Volume: 2 ft * 4 ft * 3 ft = 24 ft^3
Total Volume = 24 ft^3 + 80 ft^3 + 24 ft^3 = 128 ft^3
Answer:
v = [tex]108^{3}[/tex]
Step-by-step explanation:
I'd start with breaking the platform into two parts, the long flat rectangle and then the bit on top. You'll have to add these together at the end!
_________________
So part one: the long piece
formula: v = lwh
dimensions: 12, 3, 2
plug in: v = 12 * 3 * 2
solve: v = 72^3
_________________
part two: smaller rectangle on top ::
formula: v = lwh
dimensions: 4, 3, 3
plug in: v = 4 * 3 * 3
solve:v = 36*3
__________________
now, we add for the total of the entire shape!
final answer: 72 + 36 = 108^3

Shen needs to read 2 novels each month
Let N be the number of novels Shen needs to read in M months.
Write an equation relating N to M. Then use this equation to find the number of novels Shen needs to read in 13 months.
Answers
Answer:
Equation: N = 2M, Shen needs to read 26 novels in 13 months
Step-by-step explanation:
Given : Shen needs to read 2 novels each month.
i.e. In One month , the number of novels read by Shen = 2
Let N be the number of novels Shen needs to read in M months.
Then , N = 2 M
Thus , the equation relating N to M : N = 2 M
If Number of months = 13 , then put M = 13 in the above equations , we get
N = 2(13) = 26
Hence, the number of novels he read in 13 months = 26.

Jack has a mask collection of 500 masks. He keeps 235 of the masks on his wall. What percentage of Jack's mask collection does he keep on his wall?
Answers
Answer:
47%
Step-by-step explanation:
First we need to find the ratio of masks on Jack's wall to the total number of masks, which is 235/500. Now we need to make the denominator 100 in order to find the percentage by dividing the numerator and denominator by 5 to get 47/100. Therefore the percentage of Jack's mask collection that is on his wall is 47%.

Find the sum of the first 40 terms of the arithmetic sequence.
14, 4, -6, -16, -26, -36
Answers
Answer:
-7240
Step-by-step explanation:
The nth term is -10n + 24.
So the combination of the first and second term would be (-10+24)+(-10x2+24) and this would continue for the first 40 terms so the 24s would add up to 24x40=960. Meanwhile, the -10s would keep adding up so it would be -10-20-30-40.... which you can simplify by making it -10(1+2+3+4) all the way to 40 to make the calculation easier... u can further simplify by making 41 = one pair of numbers so 40+1, 39+2 until you get 21+20 so ur left with -10(20 pairs of 41) so -10(20x41) = -10(820)= -8200.
Add this to your initial 960 so
-8200 +960 = -7240

Is 16+4 and 2(2w+8) equivalent?
Answers
Answer:
Below!
Step-by-step explanation:
Let us consider that 16 + 4 and 2(2w+8) are equal. Then;
⇒ 16 + 4 = 2(2w + 8)This equation can be solved in two ways. Listed below!
Method 1:
Let's simplify the left-hand-side of the equation.
⇒ 20 = 2(2w + 8)Then, divide "2" both sides of the equation to open the parentheses.
⇒ 20/2 = 2(2w + 8)/2⇒ 10 = (2w + 8)⇒ 10 = 2w + 8Subtract 8 to both sides of the equation to isolate the variable (w) and it's coefficient.
⇒ 10 - 8 = 2w⇒ 2 = 2wFinally, divide 2 to both sides of the equation to isolate the variable (w).
⇒ w = 1Therefore, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.
Method 2:
Let's simplify the left-hand-side of the equation.
⇒ 20 = 2(2w + 8)Then, simplify the distributive property to open the parentheses.
⇒ 20 = 2(2w + 8)⇒ 20 = 4w + 16Subtract 16 to both sides of the equation to isolate the variable and it's coefficient.
⇒ 20 - 16 = 4w + 16 - 16⇒ 4 = 4wFinally, divide 4 to both sides of the equation to isolate the variable (w).
⇒ 4/4 = 4w/4⇒ w = 1As said in method 1, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.

There are 2 triangles and 6 circles. What is the simplest ratio of triangles to circles?
Answers
Hi!
We are asked to find the ratio.
A ratio is a relationship/comparison between two or more numbers based on their numerical value.
We know that, for every 2 triangles there are 6 circles. We can set up our ratio to look like this:
[tex]\cfrac{2}{6}[/tex]
---
(NOTE: there are many different ways to write ratios, including: "x:y", "x to y", or "x/y")
---
The question asks us to write it in simplest form. The fraction [tex]\cfrac{2}{6}[/tex] is NOT in simplest form. It can be simplified to:
[tex]\cfrac{1}{3}[/tex]
This is the ratio in simplest form.
