Answer:
one 20 inch pizza
Step-by-step explanation:
radius of one 10 inch pizza is 10/2 = 5
so area of one 10 inch pizza : [tex]\pi[/tex]× [tex]5^{2}[/tex] = 25 [tex]\pi[/tex]
there are 2 ; 10 inch pizza so 25 [tex]\pi[/tex]⇒[tex]50\pi[/tex]
however 20 inch pizza radius is 10
so
[tex]10^{2}[/tex]×[tex]\pi[/tex] = 100[tex]\pi[/tex]

is -0.75 bigger or less than -0.4?
Answer:
Because they are both negative that means they are on the left side so -0.4 is closer to the 0 so less.
What 2 whole numbers is the square root of 75 between?
Answer:
8 and 9
Step-by-step explanation:
Rate of change and slope. Can anybody help me? This is a major and I do not understand the problem.
Step-by-step explanation:
1. the rate of change is constant. the slope is 3
2. the rate of change is variable, because it's not consistent.
Some number added to -12 is 36. Add this number to -15. Then multiply this
number by 2. What is the final number?
What's the additive inverse of 0.75.
Answer:
[tex]additive \: inverse = - 0.75[/tex]
My old account is h acked lol <3
Answer:
PUK me montoon are 8ii88iiii8
Help please.
Is algebra.
Answer:
3
Step-by-step explanation:
To find the average rate of change, we can use the formula: (y2-y1) / (x2-x1).
Let (15, 45) be (x1, y1) and (29, 87) be (x2, y2).
So we have: (87-45) / (29-15)
This can be simplified to: 42/14, or 3.
Let me know if this helps!

Solve for the inequality x / 3 < -7
Answer:
[tex]x < - 21[/tex]
Step-by-step explanation:
1. Multiply both sides by 3.
[tex]x < - 7 \times 3[/tex]
2. Simplify 3 × 7 to 21.
[tex]x < - 21[/tex]
therefor, the answer is x < -21
HELP HELP HELP HELP The answer is not 34.5 or 124.5
Answer:
x=37, Angle A is 74. Exterior angle B is 185
Step-by-step explanation:
I'm pretty sure this right but This is a triangle that is folded to the inside. This means that most likely there is a negative interior degree
angle. Using the interior theorem, we can add up all the non adjacent sides to find the exterior angle of the adjacent side. 79+2x+32=5x, 2x+111=5x, 111=3x, x=37. Then plug 37 in for x Angle A is 74 degree and B exterior angle Is 185 degree.

Find the inverse of f(x) = √x-1
Answer:
Step-by-step explanation:
For a function to have an inverse, it has to pass the horizontal and vertical line test, yes both of them. This function does, so we can continue. The first step for finding an inverse is replacing f(x) with y. Then switch the places of x and y.
[tex]x=\sqrt{y-1}[/tex]
Now the next step is to solve for this new y value, which is equivalent to f^-1(x). Square both sides to get rid of the radical.
[tex]x^2=y-1[/tex]
Add 1 to both sides and that is your inverse function
[tex]y=x^2+1[/tex]
What is an equation of the line that passes through the points -6, -2 and 6,-2
Answer:
y = 2
Step-by-step explanation:
m = (2 - 2)/(6 - (-6))
m = 0
there's no slope, so it's just 2
As you can see the 2 points have the same y coordinate that means the line passing through it is going to be a horizontal line with a consistent y level of -2.
The equation will be just what I said y=2
Hope this helped!

Answer:
9) 5/10
10) 4/5
Step-by-step explanation:
A terminating decimal is a decimal that stops eventually
2/3 = 0.6666666...
5/6 = 0.833333...
5/10 = 0.5
6/9 = 0.6666666...
5/10 has a result of a terminating decimal
8/9 = 0.888888...
1/7 = 0.142857...
4/5 = 0.8
4/11 = 0.36363636....
solve the equation below
-3 (x+7) =9
Answer:
x=-10
Step-by-step explanation:
-3(x+7)=9
-3x-21=9
add 21 to both sides of equation
simplify divide both sides by like terms
simplify again and you have your answer

Actually Welcome to the Concept of the Surface areas and Volume.
Since Box A is cube, it's volume is Side^3
hence taking the cube root of 512 , we get as,
Side length of Box A is 8 m.
hence diving 8/2 = 4 m
4 m is a side of Box B.
hence, Volume of Box B is = (4)^3 = 64 cubic metres.
Vol. Box B = 64 m^3
Answer:
The correct answer is D: 64 meters cubed
Step-by-step explanation:
You can take any example but let's say 128 times 2 times 2 which equals box A, now you must divide all dimensions by 2 and you will get 64 times 1 times 1 which adds up to 64, this will work with any example.

Answer:
(-4,1)
Step-by-step explanation:
The answer is just where the two lines intersect
I'm rather tired so double check me on this but I'm getting about (-4,1) and it's asking for an approximation so think (-4,1) is fine
Answer:
It's around (-4. 5, 1.5). It's somewhere in that range.
