Answer:
18
Step-by-step explanation:
when rounding to the nearest whole number, if the number after the decimal is less than 5, than the whole number would stay the same. If the number after the decimal is 5 or greater, than the whole number would be one greater.
Hello!
<h2>Answer:</h2>
<h2>__________________________________________________</h2><h2>Explanation:</h2>
We'll start by calculating the areas of Kylie and Paige's circles.
Kylie's Circle:
A = πr²
Since we need the radius for the formula, we must divide the diameter in half to get it.
r = d ÷ 2
r = 8 ÷ 2
r = 4
Now, let's substitute our values into the formula.
A = 3.14 × 4²
A = 3.14 × 16
A = 50.24 cm²
Paige's Circle:
A = πr²
A = 3.14 × 3²
A = 3.14 × 9
A = 28.26 cm²
We can round both of these areas to the nearest whole number. Then, we must subtract Paige's circle area by Kylie's.
50 - 28 = 22
Answer:
A is graph 3
B is graph 1
C is graph 2
Step-by-step explanation:
A is graph 3 because it’s says that she begins with at least a total of 80 os the y should not start at 0, instead it should, start at 80 but every time she gets a question wrong the graph keeps going down.
B is graph 2 because it States that Heath has 10 pennies to begin with so the y isnt 0 but 10 and every time she doubles it the graph only goes up.
C is graph 1 because it states that to Exeter a school fair it’s 5 bucks but each ticket cost 50 cents so it starts at 5 then keeps going up.
(I’m 100% sure of A but I’m not really sure about B and C but this is my best guess)
Answer:
Solution: (-4,5)
Step-by-step explanation:
x=16-4y
3x+4y=8
-----
The 1st equation tells you x = 16-4y
---
Substitute that into the 2nd equation
and solve for "y":
3(16-4y)+4y = 8
48 - 12y + 4y = 8
-8y = -40
---
y = 5
---
Solve for "x"
x = 16-4y
x = 16-4*5
x = 16-20
x = -4
I would divide 12 by 10 and after doing that, I would get 1.2. Hope this helps!
