Answer:

C.y=5, x=10

Step-by-step explanation:

In this case when you have a triangle that is being cut by paralell lines you can use the Triangle Proportionality Theorem, which states that a triangle that is cut by a parallel line to any side the resultant sides would be proportional to those of the original triangle.

So you equation would be like this:

\frac{15}{12} =\frac{y}{4}

If you clear the function to get the value of X it´ll look like this:

y=\frac{15*4}{12}

y=\frac{60}{12}

y=5

Now that we have calculated the length of Y we can calculate the length of X

Since x+y=15

Then

x=15-y

x=15-5

x=10

So the value of X would be 10.

Tickets to the movies are $7 for adults and $4 for children. If 272 tickets
rewona [7]

Answer:

202 tickets for adults were sold and 70 tickets for children are sold.

Step-by-step explanation:

Solve this question using simultaneous linear equation.

•Let the number of tickets sold for adults be a

•Let the number of tickets sold for children be b

The question stated that 272 tickets were sold altogether. So:

a + b = 272

Now, make sure that only one of the unknown values remain on the left hand side. For example:

a = 272 - b

I will refer to the above equation as equation 1.

Now, the question also stated that the tickets sold $1694. This means that:

7a + 4b = 1694

I will refer to this equation as equation 2.

Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:

7(272 - b) + 4b = 1694

Then just solve the equation by finding the value of b.

7(272 - b) + 4b = 1694 \\ 1904 - 7b + 4b = 1694 \\ 1904 - 3b = 1694 \\ 1904 - 1694 = 3b \\ 210 = 3b \\ b = 210 \div 3 \\  = 70

Lastly, find the value of a. Just take the value of b and then substitute into equation 1.

a  = 272 - b \\  = 272 - 70 \\ a = 202

pd-100 has a half-life of 3.6 days. if one had 6.02 x 1023 atoms at the start, how many atoms would be present after 20.0 days?
Irina18 [472]
<span>half-life means you divide by 2 
21.6 / 3.6 = 6 hf (hf = half-life) 
then you divide by 2^6 
6.02 x 10^23 / 2^6 = 9.40625 x 10^21 atoms 
-------------- 
26 
3hf ===> 2^3 
10.0 / 2^3 = 1.25 gram (remaining) 
answer : 10 - 1.25 = 8.75g 
------- 
27 
128 / 2^n = 2 
64 = 2^n 
n = 6 
24 /6 = 4  
4 days is the half-live of the sample 
----------- 
28 
2.5/4.46 of 50% initial mass 
(2.5/4.46) x 0.5 x 2 = 0.5605 g 
answer: 2 - 0.5605 = 1.4395 g 
---------- 
29 
2^7 = 128 
so 7 half-lifes 
7* 8040 = 56200 days 
---------- 
30 
the time of 10 half-lifes 
= 10 x 0.334s = 3.34s </span><span>
