Answer: 13 dimes and 7 quarters I think
Step-by-step explanation:
Adding all of these should equal to 180 from the way the angle is set up.
So the equation should be:
(3x + 2) + (2x + 5) + (2x - 9) = 180
You can remove parentheses as it doesn’t affect the equation since it is all addition.
Let’s first add the common variables together.
3x + 2x + 2x = 7x
2 + 5 + (-9) = -2
So now we should have:
7x - 2 = 180
Now add 2 to both sides.
7x = 182
Divide both sides by 7 to isolate x.
x = 26
So x is 26.
1130.97 is the surface area of the cylinder
Use pythagoras teorem
10^2 = 3^2 + x^2
x^2 = 100 - 9 = 91
x = 9.54 feet to nearest hundredth
Answer:
- a. 1 / 13
- b. 3 / 13
- c. 10 / 13
Step-by-step explanation:
<h3>a.</h3>
There are four 5's in the deck. This means that, from 52 possible cards to drawn, we have 4 chances of drawing a 5. This means that the probability will be:


<h3>
b.</h3>
For every suit, there are three face cards, J, Q and K. There are 4 suits, so, the total number of face cards its:

The total possible cards are, still, 52, so, the probability will be


<h3>
c.</h3>
We know that the card drawn must be a face card, o not being a face card. There is no third choice here. So, the probability of drawing a face card OR not drawing a face car its:

so


but, we know that

so
