Answer:

Step-by-step explanation:

Recall these rules of logs: log a + log b = log (ab), and log a^b = b log a

Then 3 log q = log q^3 and 6 log v = log v^6, and

log q^3 + 6 log v becomes log q^3 * v^6

Now rewrite this using b as the base:

log q^3 * v^6

Angles A and B are supplementary. Angle A has a measure of 80 degrees. What is the measure of angle B?

Aleonysh [2.5K]

Supplementary angles, when added, equal 180 degrees

so < A + < B = 180...and if < A = 80
80 + < B = 180
< B = 180 - 80
< B = 100 <==

Please help i am super confused on what to do :)

Answer:

About 9.1 yards tall.

Step-by-step explanation:

So, we can draw the right triangle shown below:

We want to find h.

Since we know the angle and the side adjacent to the angle and we wan to find the opposite side, we will use the tangent ratio:

$\displaystyle \tan(x^\circ)=\frac{\text{Opposite}}{\text{Adjacent}}$

So:

$\displaystyle \tan(20)=\frac{h}{25}$

Therefore:

$\displaystyle h=25\tan(20)$

Use a calculator. Ensure your calculator is in the correct mode (degrees mode):

$h\approx 9.1\text{ yards}$

The goal post is around 9.1 yards tall.

There is a 15% it will rain on both Saturday and Sunday. There is a 60% chance of rain on Saturday. What is the chance of

Artemon [7]

Answer:

25%

Step-by-step explanation:

This question is about conditional probability. Let's say that the probability of raining on Saturday is X=true and the probability of raining on Sunday is Y=true. There is a 15% it will rain on both Saturday and Sunday, to put into the equation it will be:

P(X= true ∩ Y = true) = P(X = true) * P(Y = true)= 0.15

There is a 60% chance of rain on Saturday, mean the equation is

P(X = true) = 0.6

The question is asking for the chance of rain on Sunday or P(Y = true). If we substitute the second equation to first, it will be:

P(X = true) * P(Y = true)= 0.15

0.6* P(Y = true)= 0.15

P(Y = true)= 0.15/0.6

P(Y = true)= 0.25 = 25%
