I have 31 stamps in total. I have 4 more 1 cent stamps than 8 cent stamps and twice as many one cent stamps as 12 cent stamps. I

Neko [114]

Answer:

There area 14 one cent stamps

Step-by-step explanation:

Let

x -----> the number of 1 cent stamps

y -----> the number of 8 cent stamps

z -----> the number of 12 cent stamps

we know that

0.01x+0.08y+0.12z=1.78 -------> equation A

x=y+4 ------> y=x-4 -----> equation B

x=2z -----> z=0.5x ------> equation C

substitute equation B and equation C in equation A and solve for x

0.01x+0.08(x-4)+0.12(0.5x)=1.78

0.01x+0.08x-0.32+0.06x=1.78

0.15x=1.78 +0.32

0.15x=2.10

x=14

therefore

There area 14 one cent stamps

It's moving day, and Lydia has packed her books into large and small boxes. The large boxes hold 35 books, and the small ones ho

Virty [35]

The number of large boxes is 4 and the number of small boxes is 14.

<u><em>Explanation</em></u>

Suppose, the number of large boxes is $x$ and the number of small boxes is $y$

As, the total number of boxes is 18, so the first equation is....

$x+y= 18 .......................................(1)$

The large boxes hold 35 books, and the small ones hold 20 books and the total number of books is 420. So the second equation will be .....

$35x+20y=420................................(2)$

Now solving equation (1) for $y$ itself , we will get....

$y= 18-x$

We will plug this $y= 18-x$ into equation (2). So.....

$35x+20(18-x)=420\\ \\ 35x+360-20x=420\\ \\ 15x= 420-360\\ \\ 15x=60\\ \\ x= \frac{60}{15}=4$

Now plugging this $x=4$ into the equation $y= 18-x$ .......

$y= 18-4= 14$

Thus, the number of large boxes is 4 and the number of small boxes is 14.

F. A bag contains 3 red, 4 blue, 3 green, and 5 yellow marbles. What is the probability of

umka21 [38]

Answer:

Step-by-step explanation:

you first add up the marbles together. 3 + 4 + 3 +.5 = 15. Then you take the amount of green marbles their are, and make a fraction: 3/15. Then you remove one without putting it back, which is green, so you have 1 less total and one less green marbles, and you turn that into a fraction: 2/14.

First Pick: 3/15 chance of getting green

Second Pick: 2/14 chance of getting green

Then. You divide the first number by the second one.

3 / 15 = 0.2

2 / 14 = 0.142

Then to turn into percentage you move the decimal over two spots and drop the 0 and add a percentage sign:

20%

14.2% (Round Up Percentage) 15%

Which means that:

20% Probabiltiy for first pick

15% Probability for second pick
