Answer:
see explanation
Step-by-step explanation:
Before simplifying the ratios we require them to have the same units.
(1)
$4.50 = 450c, thus
90c : $4.50
= 90 : 450 ← divide both parts by 10
= 9 : 45 ← divide both parts by 9
= 1 : 5
(2)
1.2 m = 1.2 × 100 = 120 cm, thus
80 cm : 1.2 m
= 80 : 120 ← divide both parts by 10
= 8 : 12 ← divide both parts by 4
= 2 : 3
Answer: adjacent and hypotenuse
Step-by-step explanation: Cos theta is adjacent/Hypotenuse
Answer: 55/126
Step-by-step explanation:
For this equation, the easiest way to solve is to change the denominators, or bottom halves, of both fractions to be the same thing. The easiest way to do this is to multiply themselves with a “funny form” of one. A funny form of one is just a way of representing “1” with numbers that aren’t 1. “2/2” is a funny form of one. log(x)/log(x) is a funny form of one, etc..
(3/7)x(9/9)=27/63
(4/9)x(7/7)=28/63
These fractions are very close. If you are willing to settle for an unsimplified fraction, the answer here would be 27.5/63. If you aren’t willing to settle for the unsimplified form, we can multiply both fractions by a funny form of one again, most easily 2/2, and find the median of the two fractions.
(27/63)x(2/2)=54/126
(28/63)x(2/2)=56/126
The median of these two fractions is 55/126.
55/126 is exactly halfway between 3/7 and 4/9.
Answer:
<h2><em><u>
3. V = 1,498.2</u></em></h2><h2 /><h2><em><u>
4. V = 2,813.44</u></em></h2><h2 /><h2><em><u>
5. V = 96.293</u></em></h2>
Step-by-step explanation:
3. Formula of a Cylinder + Formula of a Cone = Total
V=πr^2h + V=πr^2h
/3 = total
V = 3.14 * 36 * 10 + V = 3.14 * 36 * 10/3
V = 1,130.4 + V = 376.8 = Total
<h2><em><u>
V = 1,498.2</u></em></h2>
4. Formula of Cone + Formula of Cone = Total
V=πr^2h
/3 + V=πr^2h
/3 = Total
V = 3.14 * 36 * 8/3 + V = 3.14 * 100 * 8 = Total
V = 301.44 + 2,512 = Total
<h2><em><u>
V = 2,813.44</u></em></h2>
5. Formula of a cylinder + formula of a sphere = Total
V=πr^2h + V=4
/3πr^3 = Total
V = 3.14 * 4 * 5 + V = 4/3 * 3.14 * 8
V = 62.8 + V = 33.493 = Total
<h2><em><u>
V = 96.293</u></em></h2>
DEFINITELY hope this helped,
