Answer:
Lewis can paint 320 square yards.
Step-by-step explanation:
1 quart covers 80 square yards
8 x 10=80
4 quarts covers 320 square yards
80 x 4=320
I believe that the zeros would be -2 and -6, assuming that the first 2 that you wrote in the equation is supposed to be a power to the x.

V = 209.3 in^3
pi = 3.14
h = 8 in
Formula
V = 1/3 pi r^2 h
209.3 = 1/3 * 3.14 * r^2 * h Multiply both sides by 3
209.3 * 3 = 3.14 * r^2 * 8
627.9 = 3.14 * r^2 Divide by 3.14
627.9/3.14 = r^2 * hThis rounds to 200
199.968 = r^2 * 8
8*r^2 = 199.968 Divide by 8
r^2 = 199.968 / 8
r^2 = 24.996
r = sqrt(24.996)
r = 4.9996 That's not quiet the answer.
diameter = 2*r
diameter = 2* 4.9996
diameter = 9.9992
d = 9.9992 <<<<< answer
You might want to think about rounding to 10 when you enter your answer.
Answer:
The distance between them
is 67 miles
Step-by-step explanation:
Here, we want to know how far apart they both are
From the question, the time they have both driven is 1 hour
Mathematically;
distance = speed * time
For Matt,
distance Is = 45 * 1 = 45 m
For John
distance is 50 * 1 = 50 m
To find the distance between them, we will use pythagoras’ theorem which states that the square of the hypotenuse is equal to the sum of the squares of the two other sides
In this question, the hypotenuse is the distance between the two sides
Thus; we have
D^2 = 45^2 + 50^2
D^2 = 2025 + 2500
D^2 = 4525
D = √4525
D = 67.27
this is approximately 67 miles
These girls really need to get their cookie situation organized!
Alright, so... first let's get this problem into a simpler form.
They made 3/5 of the total, then 2 dozen which = 24 and they still have to make 1/3 more.
So to make 3/5 and 1/3 more compatible, find the LCM of the Denominator. This = 15. 5*3=15 so take 3 (from 3/5) and multiply by 3, which is 9.
This turns 3/5 to 9/15
Then do the same to the other fraction. The Denominator (3) x 5 = 15, so take the Numerator (1)x5= 5.
This turns 1/3 to 5/15
Now that this is a little more clear, let's look at the problem with our equal and substituted values.
They made 9/15 of the total, then 2 dozen which = 24 and they still have to make 5/15 more.
So from this, we can see that after they made 24 (2 Dozen) that they need 5/15 more. 15/15 would mean they're done, so that minus 5/15 = 10/15.
The difference from 9/15 & 10/15 is 1/15. This is how much was added when they made 24 more. So now we know that 1/15=24.
With this information, we can finally solve the problem.
They plan to bake 15/15 of the cookies. This is just a term that is equal to 1 whole. The "whole" is the whole amount of cookies being baked. Since 1/15=24, we can figure out 15/15 by taking 15x24.
15 x 24 = 360. So they made 360 cookies. Sounds delicious.
I hope this helped! And hopefully these imaginary friends sell all 360 cookies!
