1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.
Answer:
C) twice the radius

Answer:
y
=
8
Step-by-step explanation:
Explanation:
the initial statement is
y
∝
x
to convert to an equation multiply by k the constant
of variation
⇒
y
=
k
x
to find k, use the given condition for x and y
y
=
10
when
x
=
5
y
=
k
x
⇒
k
=
y
x
=
10

Answer: 3.3 × 10⁹
Concept:
When multiplying exponents, add the exponents together.
When dividing exponents, subtract the exponents.
Solve:
<u>Given expression</u>
(3 × 10⁴) × (1.1 × 10⁵)
<u />
<u>Put like terms together</u>
=3 × 1.1 × 10⁴ × 10⁵
<u>Combine like terms</u>
=3.3 × 10⁴⁺⁵
=
