Which set of numbers could represent the lengths of the sides of a right triangle?
12, 18, 22
8. 15. 17
10. 15.20
7.9.11
Answer:
8, 15, 17
Step-by-step explanation:
The 2nd option. You know this by using this math formula: a^2 + b^2 = c^2. That is the formula to find a right triangle. So if you square 8 and 15 you get 64 and 225, and if you add them together you get 289, which is 17^2. Hope this helps! :)
8% of x is 20.
Plz help
Answer: 250 im not sure if its correct though
Step-by-step explanation: 8% = 8/100
8 /100 × x = 20
Multiplying both sides by 100 and dividing both sides by 8,
we have x = 20 × 100 /8
x = 250
If you are using a calculator, simply enter 20×100÷8, which will give you the answer.

4 When a ball bounces, the heights of consecutive bounces form
a geometric sequence. The height of the first bounce is
121 centimeters and the height of the third bounce is
64 centimeters. To the nearest centimeter, what is the height of the
fifth bounce?
Answer:
34 cm
Step-by-step explanation:
The nth term of a geometric progression Tₙ = arⁿ⁻¹ where a = first term, and r = common ratio.
Given that our first term, T₁ = ar¹⁻¹ = a = 121 cm and our third term T₃ = ar³⁻¹ = ar² = 64 cm
Then, T₃/T₁ = ar²/a = r²
r² = T₃/T₁
r² = 64 cm/121 cm
r = √64/121
r = 8/11
So, the height of our fifth bounce T₅ = ar⁵⁻¹
= ar⁴
= 121 cm × (8/11)⁴
= 121 × 4096/14641
= 4096/121 cm
= 33.9 cm
≅ 34 cm to the nearest cm
Using a geometric sequence, it is found that the height of the fifth bounce is of 33.85 cm.
In a geometric sequence, the quotient between consecutive terms is always the same, and it is called common ratio r.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1r^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem:
The height of the first bounce is of 121 cm, hence [tex]a_1 = 121[/tex].The height of the third bounce is of 64 cm, hence [tex]a_3 = 64[/tex], and this is used to find r.[tex]a_n = a_1r^{n-1}[/tex]
[tex]64 = 121r^{2}[/tex]
[tex]r^2 = \sqrt{\frac{64}{121}}[/tex]
[tex]r = \frac{8}{11}[/tex]
Hence:
[tex]a_n = 121\left(\frac{8}{11}\right)^{n-1}[/tex]
The height of the fifth bounce is of [tex]a_5[/tex], hence:
[tex]a_5 = 121\left(\frac{8}{11}\right)^{4} = 33.85[/tex]
The height of the fifth bounce is of 33.85 cm.

Brainiest answer to whoever is correct
2(6x + 1) - 4(x - 5) = -2
Answer:
x=−3
Step-by-step explanation:
2(6x+1)−4(x−5)=−2
Step 1: Simplify both sides of the equation.
2(6x+1)−4(x−5)=−2
(2)(6x)+(2)(1)+(−4)(x)+(−4)(−5)=−2(Distribute)
12x+2+−4x+20=−2
(12x+−4x)+(2+20)=−2(Combine Like Terms)
8x+22=−2
8x+22=−2
Step 2: Subtract 22 from both sides.
8x+22−22=−2−22
8x=−24
Step 3: Divide both sides by 8.
8x/8=−24/8

Answer:
4000π cm^2
Step-by-step explanation:
first we change the 1.6m to cm:
1.6m = 160cm
Now we can use the formula:
V = πr^2h
where π is just π, r is the radius (not the diameter) and h is the height
V = π * 5^2 * 160 = 4000π cm
Answer:
Step-by-step explanation:
[tex]\text{They give you the equation for the volume.}\\ \\ V=\pi r^2h\\ \\ \text{You simply need to plug in the values given to you for r and h.}\\ \\ r=10/2=5cm,\ h=1.6m(100cm/m)=160cm\\ \\
V=\pi 5^2(160)\\ \\ V=160(25)\pi\\ \\ V=4000\pi cm^3\\ \\ V\approx 12566.37 cm^3[/tex]

Problem situation:
Janelle is at the movie theater and has $20
to spend.
She spends $8 on a ticket and wants to buy some snacks. Each snack costs $4.99.
How many snacks, x, can Janelle buy?
Inequality that represents this situation:
20 > 8 + 4.99x
Drag each number to show if it is a solution to both the inequality and the problem
situation, to the inequality only, or if it is not a solution.
Answer:
Rewrite so x is on the left side of the inequality.
8 + 4.99x < 20
Move all terms not containing x to the right side of the inequality.
4.99x < 12
Divide each term by 4.99 and simplify.
x < 2.405

Sara and 3 of her friends went to lunch one day. Each person paid for her own lunch, but they agreed to split the tip. If the tip amount was 15% of the total, and the 4 lunches totaled $60, what was the portion of each person’s tip amount?
Answer:
Step-by-step equation:
15% of 60 is nine.
Percentage is equivalent to the portion of a quantity present in the whole. The portion of each person’s tip amount shared by Sara and 3 of her friends is $2.65.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The amount of tip is 15% of the total amount A.
The total amount of 4 lunches = $60.
As per the question, the total amount can be written as,
15% of A = A - 60
=> 15 / 100 × A = A - 60
=> A - (3 / 20) × A = 60
=> A - (3 / 20) × A = 60
=> (17 / 20) × A = 60
=> A = (60 × 20) / 17
=> A = 70.58
Now, the total amount of tip is,
15% of 70.58
(15 / 100) × 70.58 = 10.58
The tip shared by each friend = 10.58 ÷ 4
= 2.65
Hence, the portion of each person’s tip amount is $2.65.

Step-by-step explanation:
you can break it into a long rectangle in the middle with dimensions of 2(6+8) or 2(14) = 28 sq mm
the triangle on the bottom has a base of (8-4) x height of 3, which gives 6 sq mm (you have to divide by 2)
the upper left rectangle is 6 x 3 = 18 sq mm
