Answer:
Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be
The general formula is:
ρ
=
m
V
where
ρ
is density in
g/mL
if mass
m
is in
g
and volume
V
is in
mL
.
So to get the mass...
m
=
ρ
V
Or to get the volume...
V
=
m
ρ
When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.
Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.
These days, you should be able to search for the density of any common object.
When you have the density and volume but not the mass, then just make up a mass.
You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.

We know that the expression is 4x+40. How much will the length of the garden increase by if it uses 50 feet of fencing in total? Here is a photo to help.
Answer:
240
Since the expression is 4x + 40 we just substitute 50 in for x, so the new equation looks like this 4(50) + 40 which gets us 240.

Mr. Chang buys supplies for the school store. He bought 300 pencils on sale for $10. During the first three months of school, he sold 200 pencils and made $50. The other pencils were thrown away because they were broken. How much profit did Mr. Chang make on the pencils?
Answer:
$40
Step-by-step explanation:
He bought the pencils for $10, so his expense was $10. He sold the pencils for $50, and $50 - $10 is $40, and that's the total amount of money he made.

Step-by-step explanation:
Assume the two lines are parallel.
9. The corresponding angles are congruent.
9x - 3 = 7x + 11
2x = 14
x = 7
10. The alternate interior angles are congruent.

Answer:
4. 23
4. 206
5. 75 ft
7. 6 sections
8. 6 families
Step-by-step explanation:
4. 3x + 5 is the same thing as 3 x 6 + 5 so it equals to 23
4. x to the power of 3 - 10 is equal to 6 to the power of 3 - 10 so it equals to 206
5. Formula for area of triangle = 1/2 x base x height
So, it's 1/2 x 10 x 15 = 75
7. 3/4 ÷ 1/8 = 6 (Trick: When dividing fractions, make sure to flip the fraction for the 2nd one and leave the 1st one as the same. After that, multiply them together)
8. 3 families have 4-5 pets, 2 families have 6-7 pets and 1 family have 8-9 pets. At least 4 pets means 4 pets and above. So 3 + 2 + 1 = 6 families.
4. 3x + 5. Substitute the X for 6. The expression is (3 x 6) + 5= 23.
X³ - 10. Substitute the X for 6. 6³-10= 216.
5. I'm not 100% sure but I believe that it is 75. I might be wrong.
6. 6
7. 6

I NEED HELP REALLY FAST PLEASE! Find the measure of the missing angles.
Step-by-step explanation:
x+47=90
x=43
----------------
y+x=90
put in 43 for x
y+43=90
y=47
Hope that helps :)
Answer:
X=43
y=47
Step-by-step explanation:
Well you have 47 degrees. Finding X first would be easier.
X and 47 are complementary (90 degreees) so you can subtract 47 from 90 and get “x” Which is 43.
Now for y.
Y and X is complementary also, which means since x is 43, 90-43 is 47. So y is 47.

What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p : q = r : s or p/q = r/s
Given that,
Amount of food fed to Great Dane by Deon in 1 week = 62 cups
He has a new bag with 160 cups of dog food.
He needs this food to last up to 2 1/2 or 2.5 weeks.
We have,
Amount of food needed in 1 week = 62 cups
Let Amount of food needed in 2.5 weeks = x cups
Ratio of 1 week to 62 cups and 2.5 weeks to x cups will be equal.
So using proportional concept, we can write this as,
1 / 62 = 2.5 / x
We have to find the value of x.
Doing the cross multiplication,
x = 2.5 × 62 = 155 cups
So the amount of food needed in 2.5 weeks = 155 cups.
But he has a new bag with 160 cups which is more than enough for 2.5 weeks, since only 155 cups is needed for 2.5 weeks.
Hence the new bag of food will last until 2 1/2 weeks.
