There are a total of 63 bikes, if ratio of blue bikes to Black is 4 to 5 how many bikes are blue
Alexus [3.1K]

Answer:

28 bikes are blue

Step-by-step explanation:

Set up the ratio:

Blue : Black

4 : 5

Find the total # of bikes in the ratio:

4 + 5 = 9

Find the relationship between 63 and 9:

63/9 = 7

Multiply both sides of the ratio by 7:

4(7) = 28

5(7) = 35

28 : 35

Therefore, the number of blue bikes is 28.

Zielflug [23.3K]

Answer:

∠ SPQ = 75°

∠ SPQ = 360° - (90 + 74 + 121)° = 360° - 285° = 75°

The polynomial x^3-kx^2+kx+2 has a factor of (x-2). What is the value of k?
laiz [17]

\text{Let}~ f(x) = x^3-kx^2 +kx +2.\\\\\text{If}~ x-2~ \text{is a factor of}~ f(x)~ \text{then,}\\ \\f(2) =0\\\\\implies 2^3-k\cdot 2^2 +2k+2 =0\\\\\implies -4k+2k+8+2=0\\\\\implies 10-2k=0\\\\\implies 2k =10\\\\\implies k= \dfrac{10}2 = 5\\\\\\\text{Hence, the value of k is 5.}
