Answer:
C = 2π(3/8) = 3π/4 units
Step-by-step explanation: The area of the circle is given by the formula A = πr^2, where A is the area and r is the radius.Therefore, 9/64π = πr^2Simplifying, we get:r^2 = 9/64Taking the square root of both sides, we get:r = 3/8The circumference of a circle is given by the formula C = 2πr, where C is the circumference and r is the radius.Therefore, the circumference of the circle is:C = 2π(3/8) = 3π/4 units
Referring to the Fig, Mrs. Hawkins took four slips of paper
and wrote a different student's name on each. Two of the names were
boys and two girls. She put the four slips of paper in a bag and said
she is going to draw two slips out. She then drew the tree diagram
to show the different outcomes that are possible. "B" represents a
boy's name and "G" represents a girl's name. What is the theoretical
probability that the teacher draws two names that are the opposite sex?
a. 2/3 c. 1/3
b. 3/4 d. 7/12
Answer: 2/3
Step-by-step explanation: When the teacher pulls a B you can see that the probability is 2 G's to 1 B so you have a 2 in 3 chance of pulling a G
What is the effect of multiplying both sides of an inequality by a negative number? Explain and give an example.
Answer: You would swap the ineqaulity
Step-by-step explanation:
Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to >, and vice versa. For example, given that 5 < 8 we can multiply both sides by 6 to obtain 30 < 48 which is still true.

Select all the expressions that are equivalent to –8.
A)80100
B)–800100
C)80 ÷ (–10)
D)–80 ÷ (–10)
E)−80−100
Answer:
The only one I can see right now is (C)
Step-by-step explanation:
Because a positive divided by a negative is negative, so 80/-10 is -8.
For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers? I can help in comments if you tell me.
The expressions that are equivalent to –8 is only option C i. e 80 ÷ (–10)
What is Expression?Expression is a combination of operators, variables and numbers
Two expressions are said to be equivalent when we solve both we get the same answer.
For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers
For option C, –8 is equivalent to 80/-10 because a positive divided by a negative is negative, so 80/-10 is -8.
For option D, –8 is not equivalent to -80/-10 because a positive divided by a positive is positive, so -80/-10 is 8.
So option C is equivalent to -8.

E.Total cost for two sweatshirts is $41.28.
Answer:

Step-by-step explanation:
because im big brain
Answer:
A, D, and E
Step-by-step explanation:
I did all the math
20% of 16 = 3.2
3.2 + 16 = 19.20
7.5% of 19.20 = 1.44
1.44 x 2 = 2.88
19.20 x 2 = 38.4
38.4 + 2.88 = 41.28

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Answer:
You're correct. x= 28
Step-by-step explanation:
2x - 49 + x + 90 + 55 = 180
2x - 49 + x + 145 = 180
3x - 49 + 145 = 180
3x + 96 = 180
3x + 96 - 96 = 180 - 96
3x = 84
3x/3 = 84/3
x= 28

Answer:
13/8 in
Step-by-step explanation:
1) Since you know that there are 2 sticks with a length of 1/8 in, 3 sticks with a length of 2/8 in, and 1 stick with the length of 5/8 in, we need to add them together.
2) They have the same denominator, so we can add the fractions together easily. 1/8+1/8+2/8+2/8+2/8+5/8=13/8

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

d = t. 610
in your own words, describe the equation's meaning. What does each part of the equation represent?
It should be noted that the equation for the Denver to Chicago situation is d = t. 610. This implies that the distance is 610 miles multiplied by the time taken.
How to illustrate the information?It should be noted that an equation is used to show the relationship that can be found between the data or variable that are given.

Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which two numbers the length of the third side must fall.) Write an inequality.
8 and 13
Explanation:
Let x be the length of the third side. We can't find the exact value of x, as we don't have enough info, but we can find possible values for x.
The lower boundary for x is 13-8 = 5. It must be larger than this value.
At the same time, x must be smaller than 13+8 = 21 as well.
So x > 5 and x < 21 becomes 5 < x < 21
In short, x is between 5 and 21. It cannot equal either endpoint.
