Answer:
10+4h
Step-by-step explanation:
variation
the constant $10+the variable( 4×hpw many hours used).will give me that answer.
This one could be 8/10, or 4/5 simplified
63 and 84 are both divisible by 21 63/21=3 84/21=4 the reduced form would be 3/4
Answer:
Step-by-step explanation:
We are asked to find the density of a cylinder whose volume is 1000.0 cubic cm and mass is 556 grams.
Substitute the given values:
Therefore, the density of the metallic cylinder is 0.556 grams per cubic centimeter.
(3m+5n)(9m²-15mn+25n²)
1) Let's factorize 27m³ +125n³.
27m³ +125n³ <em>Let's use x³ +y³ product to factorize that</em>
<em />
x³ +y³ = (x +y)(x²-xy +y²)
2) So let's rewrite it, since 3³ = 27 and 5³ = 125
27m³ +125n³ =
Plug x =3m and y = 5n into those factors (x +y)(x²-xy +y²)
27m³ +125n³= (3m + 5n)(3²m² -5n*3m +5²n²)
27m³ +125n³= (3m+5n)(9m² - 15mn +25n²)
3) So the answer is
(3m+5n)(9m²-15mn+25n²)
