Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
using the cosine ratio in the right triangle
cos71° =
=
=
( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC =
≈ 19.4 cm ( to 3 sig. figs )
Answer:
see below for a graph
Step-by-step explanation:
The equation is in slope-intercept form, so right away you know one point is the y-intercept: (0, -4).
Another point can be found using the slope, which is 3/2, to go 2 units to the right and 3 units up. (Slope = rise/run, so rise = 3 and run = 2 match the slope.)

Answer:
(0,7)
Step-by-step explanation:
Hi there!
To find equivalent fractions, we need to multiply both the numerator and the denominator by the same number.
These equivalent fractions are the original fractions multiplied by 2/2:
2/3 = 4/6
1/2 = 2/4
5/12 = 10/24
Hope this helps!
