How to find a measure of angle A?

vodomira [7]

To find the measure of the smallest angle of the triangle, we multiply 4 times 10. So, 4 x 10 = 40. Remember, the sum of the angles of a triangle is 180 degrees. Just take what you are given in a problem and try to determine what will make the final angle add up to 180 degrees. Hope this helps even though it probably won’t :D

A worm travels 1250 millimeters.how many meters did the worm travel?

Trava [24]

we know that

$1\ meter=1,000\ millimeters$

by proportion

$\frac{1}{1,000}\frac{m}{mm} =\frac{x}{1,250}\frac{m}{mm} \\ \\1,000*x=1,250\\ \\x=1,250/1,000\\ \\x=1.25\ m$

therefore

the answer is

$1.25\ m$

Part B

yan [13]

Using the probability concept, it is found that there is a 0.8456= 84.56% probability that client A lives to be 20 years old.

<h3 /><h3>What is probability?</h3>

A probability is the chances of happening of any event from the random variables. A probability is the number of desired outcomes divided by the number of total outcomes, that is:

$P=\dfrac{D}{T}$

In this problem:

Out of 100,000 clients, 84,560 lives to age 64, hence

Then:

$P=\dfrac{84560}{100000}=84.56\%$

There is a 0.8456= 84.56% probability that client A lives to be 30 years old.

(URGENT)use the vectors to determine two dot products<br>

MAXImum [283]

u = 9 i - 6 j

v = -3 i - 2j

w = 19 i + 15 j

u • v = (9 i - 6 j) • (-3 i - 2j)

Distribute the dot products:

u • v = 9*(-3) (i • i) + 9*(-2) (i • j) + (-6)*(-3) (j • i) + (-6)*(-2) (j • j)

i and j are orthogonal unit vectors, so their dot products are 0, while i • i = j • j = 1. So we have

u • v = 9*(-3) + (-6)*(-2) = -27 + 12 = -15

In other words, the dot product can be computed by simply multiplying corresponding components, and taking the total.

u • w = 9*19 + (-6)*15 = 81
