Answer:
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3).
Step-by-step explanation:
Answer:
-31
Step-by-step explanation:
since x+5 is a factor then
x=(-5)
f(-5)=-5×3-4×2+3×-5+7
=-15-8-15+7
=-30-1
=-31
Answer:
Step-by-step explanation:
(new - original)/original = mark up
(78.08-64)/64= mark up
14.08/64 =mark up
.22 = mark up
multiply by 100 to get to a percent
mark up = 22 percent
Answer:
103.65 mph
Step-by-step explanation:
A bearing of 250 deg is 200 deg on the coordinate plane.
Find the x- and y-components of the speed vectors. Add them. Then find the magnitude of the resultant.
Hx = 110 cos 200° = -103.366
Hy = 110 sin 200° = -37.622
Ax = 0
Ay = 30
Hx + Ax = -103.366
Hy + Ay = -37.622 + 30 = -7.622
sqrt(-103.366^2 + -7.622^2) = 103.65
Answer: 103.65 mph
