∠A and ∠B are supplementary angles. If m∠A = (3x+1)∘ and m∠B = (x-9)∘, then find the measure of ∠B.
Answer:
X= 45
Step-by-step explanation:
So you do
3x+1+x-9=180
Because supplementary angles are 180°
Then
3x+x = 4x
1 - 9 = -10
4x-10=180
4x-10+(10)=180+(10)
4x=190
x=45

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
Pls, help! A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number less than 3. Find the probability of not rolling a number less than 3.
1/3; 2/3
1/2; 1/2
5/6; 1/2
1/6; 5/6
Brainlist for positive attitude and correct answer :D
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Your cousin is building a sandbox for his daughter.
How much sand will he need to fill the box? Explain.
How much paint will he need to paint all six surfaces of the sandbox? Explain.
Answer:
Explained below...
Step-by-step explanation:
So, I believe that for the first question, you are finding the volume. Volume is what makes up the inside of a 3- dimensional shape.
So, as you may know, the formula for volume is length x width x height.
This means you will multiply 1, 4, and 6 feet. (1 * 4 * 6, which equals 24) So, I would say 24 pounds? I am unsure, but I hope this helps!
For question 2, you will have to find the area of each rectangle. With a concluding fact that the opposing sides are similar, this will make things easier.
First, locate all of your measurements for area (A = l * w) So, for the smaller rectangle, or two short sides, you will multiply 1 by 4, which is 4. For the longer sides, you will multiply 1 by 6, which is 6. For the top and bottom, you will multiply 6 by 4, which is 24.
Don't forget to remember that there are two of each rectangle!
Considering he will have to cover a total of 68 feet, I am sadly unsure of how many.
Hope this helps! :)
I'm sorry if it doesn't. You may delete my answer if it does not.

i'm so confuzzled, please help
Step-by-step explanation:
0.5% of w is 12 is what they are asking
0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is
\(12 = 0.005 \times w\)
Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite
\(w = \frac{12}{0.005} = 2400\)
Answer:

in wich of the tables are x and y inversely proportional
A
x=1,2,3,4
y=6,3,2,1.5
B
x=2,3,5,7
y=7.5,5,3,2
C
x=1,3,4,24
y=24,8,6,1
D:
x=0.1,0.3,25,100
y=200,40,0.8,0.2
Answer:
A, C
Step-by-step explanation:
If it is inversely proportional then y = k/x
Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)
A.
6 = k/1 (k=6)
3 = k/2 (k=6)
2 = k/3 (k=6)
1.5 = k/4 (k=6)
Yes! It's the same everywhere so this is correct!
B.
7.5 = k/2 (k=15)
5 = k/3 (k=15)
3 = k/5 (k=15)
2 = k/7 (k=14)
For the last one k is not the same so nope. It is wrong.
C.
24 = k/1 (k=24)
8 = k/3 (k=24)
k = 6×4 = 24
k = 24×1 = 24
This is correct too.
D.
k = 0.1×200 = 20
k = 0.3×40 = 12
k = 0.8 × 25 = 20
We can already see that k is not the same everywhere.
Only A and C, x and y are inversely proportional for all of the values

The graph shows a reading between 1,200 and 1,500, so it can be presumed that the initial investment was aroundabout $1,350.
The sum of two consecutive even integers is 38.
Let x represent the smaller of the two integers.
Which expression represents the larger of the two integers?
Translate the sentence into an equation by dragging the correct expressions into the boxes.
Answer:
Large integer = x + 2
x + 2 + x = 38
Step-by-step explanation:
Large integer = x + 2
x + 2 + x = 38
ex. 2. 4. 6.
x. x+2. x+4
x+2 is the expression which represents the larger of the two integers and x+x+2=38 is the required equation.
Let's represent the two consecutive even integers as x and x + 2, where x is the smaller integer, and x + 2 is the larger integer.
Since the sum of the two integers is 38, we can set up an equation as follows:
x + (x + 2) = 38
Now, we can solve this equation to find the value of x and then find the larger integer (x + 2).
To find the larger integer, we need to drag the correct expression, which is (x + 2), into the box:
Larger integer: (x + 2)
Hence, larger integer is x+2 and x+x+2=38 is the required equation.
