A).1090 π in²
B).1270 π in²
C).6715 π in²
D).5625 π in²
Answer:
D.) 5625 pi inches squared
Step-by-step explanation:
square root of 625 = 25
25 x 3 = 75
A= pi r(squared)
A= 75squared pi
A= 5625 pi inches squared

Find the missing side.
6 is A^2
10 is B^2
what is the missing side
Answer:
8
Step-by-step explanation:
This is a right triangle, which fits the Pythagorean Theorem, a^2 +b^2 = c^2. The variables a, b, and c all are sides of the triangle, while a and b are the two legs and c is the hypothenuse.
In this problem, we see that 6 and x are the legs and 10 is the hypothenuse. We put 6 as "a" and x as "b" (but it doesn't matter which is a and b) and 10 is c. Therefore, we have the equation:
6^2 + x^2 = 10^2
which further simplifies to:
36 + x^2 = 100
x^2 = 64
and so x would equal 8 (or -8, but it is impossible to have a side length of -8).
Therefore, the missing side is 8.
Answer:
The missing side is x=8
Step-by-step explanation:
The missing side equation is a²+b²=c²
So we plug in 6²+b²=10²
This gives us 8²
(x + 3) (2x – 7) = 0

How many solutions does the system have?
5y = 15x - 40
y = 3x -8
A. Infinitely many solutions
B. No solutions
C. Exactly one solution
Answer:
A; infinitely many solutions
Step-by-step explanation:
first, let's simplify the first equation to make it simpler.
divide both sides by 5
y=3x-8
new system
y=3x-8
y=3x-8
as you can see, they are the same.
not mandatory but useful!⬇⬇⬇⬇
just to be more clear, let's substitute them. since they're both already in y=, we can make them both set to each other.
3x-8=3x-8
add 8 to both sides; subtract 3x from one side
0=0
the answer is A, Infinitely many solutions.

2x-56=34 solve for x
Answer:
x = 45
Step-by-step explanation:
2x - 56 = 34
2x = 34 + 56
2x = 90
x = 45
Answer:
x = 45
Step-by-step explanation:
2x-56=34 add 56 to both sides
2x = 90 divide both sides by 2
x = 45

Answer:
1.9
Step-by-step explanation:
just put it into he calculator, because with 3 above the square root.
Answer:
Approximately 1.9 (rounded to the nearest tenth)
Step-by-step explanation:
First, we are left off with the equation:
[tex]y^{3} = 7[/tex]
We know we want to solve for y. So, let's do the opposite of what is being done to y. In other words, let's find the cube root of [tex]y^{3} = 7[/tex].
[tex]\sqrt[3]{y^3} = \sqrt[3]{7}[/tex]
Then, the [tex]\sqrt[3]{y^3}[/tex] just simplifies to y. On the other side, we cannot find the cube root of 7 in our minds, so that is why it tell us to use a calculator. So...
y = 1.9
Therefore, the cube root of 7 is around 1.9. Hope this helps!

You always have to use x and y as your variables when writing
equations for word problems.
Answer:
false
Step-by-step explanation:
you can use whatever letters you want to represent things. x and y make sense that you would use just them for graphing, but if it is a word problem you could have like c for cost or t for time or something
PLEASE HELP WILL GIVE BRAINLIEST:) If S (0,2) is the midpoint of RT and the coordinates of T are (3,5), find the coordinates of R.
Answer:
(-3,-1)
Step-by-step explanation:
So we need to find a number, x=a, such that when we average that number and x=3, we get x=0.
Since we want x=0 to be middle and x=3 is 3 units right of 0, then we are looking for number 3 units left of 0 which is x= -3.
Since we want y=2 to be the middle and y=5 is 3 units above 2, then we are looking for a number 3 units below 2 which is y=-1.
The other endpoint is (-3,-1).
Let's average (-3,-1) and (3,5).
(-3+3)/2=0/2=0
(-1+5)/2=4/2=2.

Pasta Place needs to make pasta with garlic cream sauce for 80 guests at a party. One batch of pasta calls for 3 cups of cream and feeds 10 people. The restaurant already has 5 pints of cream in the fridge. How many more pints of cream will they need for the pasta?
Answer:
Total pints of cream will they need for the pasta = 7 pints
Step-by-step explanation:
Given - Pasta Place needs to make pasta with garlic cream sauce for 80 guests at a party. One batch of pasta calls for 3 cups of cream and feeds 10 people. The restaurant already has 5 pints of cream in the fridge.
To find - How many more pints of cream will they need for the pasta?
Solution -
10 people = 3 cups of cream
⇒80 people = 8×3 = 24 cups of cream
Now,
We know that,
1 cup = 0.5 pints
⇒24 cup = 24×0.5 = 12 pints.
Now,
Given that, The restaurant already has 5 pints of cream in the fridge.
So,
Total pints more needed = 12 - 5 = 7 pints.
∴ we get
Total pints of cream will they need for the pasta = 7 pints

180 - 64= 116
116 divided by 4 = 29
x=29
Have a good day:>
Answer:
x = 29
Step-by-step explanation:
Supplementary angles add up to 180 degrees:
4x+64 = 180
Subtract 64 from both sides:
4x+64-64 = 180-64
4x = 116
Divide both sides by 4:
4x/4 = 116/4
x = 29
