Step-by-step explanation:
Using cross- products, that is
=
then ad = bc
Given the ratios
and
Then equating and using cross- products
If both sides equate then the ratios are equivalent
=
, then
4 × 21 = 6 × 14 ⇒ 84 = 84
Both sides are equal thus the ratios are equivalent
Answer:
Step-by-step explanation:
A linear function has the following format:
In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.
Rate of change of 3
This means that
So
A solution at (6, 12).
This means that when x = 6, y = 12. So
The linear function is:
Answer:
Step-by-step explanation:
<h2>Given that :</h2>- The radius of a circle is 2.9 in.
- Find the circumference to the nearest tenth.
- circumference = 2 × π × r
where,
- π = 22/7
- r = 2•9 inches
⟼ c = 2πr
⟼ c = 2 × 22/7 × 2•9 inches
⟼ c = 2 × 3•14 × 2•9 inches
⟼ c = 6•28 × 2•9 inches
⟼ c = 18•21 inches.
<h2>Round to the nearest tenth :</h2>⟼ c = 18•21 inches
⟼ c = 20 inches
∴ circle circumference is 20 inches .
