If the ratio of two supplementary angles is 10 to 47, calculate the measure of the larger of the two angles.

Alex73 [517]

Answer:

a) 148.52

Step-by-step explanation:

If sum of two angles is 180, then they are supplementary

Ratio = 10 : 47

Smaller angle = 10x

Larger angle = 47x

10x + 47x = 180

57x = 180

Divide both sides by 57

x = 180/57

x = 3.16

Larger angle = 47x = 47 * 3.16 = 148.52

A person draws a card from a hat. Each card is one color with the following probabilities of being drawn: 1/10 for red, 1/5 for

Kay [80]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

We are given that a card is drawn from a hat.

Probability that a red card is drawn, P(red) = $\frac{1}{10}$

Probability that a blue card is drawn, P(blue) = $\frac{1}{5}$

Probability that a black card is drawn, P(black) = $\frac{1}{20}$

Probability that a pink card is drawn, P(pink) = $\frac{1}{5}$

All these events are mutually exclusive i.e. they do not have anything in common.

For any two events A and B which are mutually exclusive, with probability P(A) and P(B), the probability that any one of the two events occur:

$P(A\cup B) = P(A) + P(B)$

Here event A can be thought of as drawing a blue card and

event B can be thought of as drawing a black card

So, P(blue or black) = P(blue) + P(black)

$\Rightarrow \dfrac{1}{5}+\dfrac{1}{20}\\\Rightarrow \dfrac{4+1}{20}\\\Rightarrow \dfrac{5}{20}\\\Rightarrow \dfrac{1}{4}$

So, the probability that a blue or black card is drawn from the hat:

$\dfrac{1}{4}$

What is the coefficient of the term of degree 7 in the polynomial below? 4 + 6x^7 + 10x - 5x^6 - 2x5

mafiozo [28]

This is in fact a polynomial of degree 7 since 7 is the highest exponent. Written correctly, these would be in order from highest degree to lowest. The coefficient (or number) that goes with the 7th degree term is a 6.
