Answer:
1.58
Step-by-step explanation:
So, we know there are 2.1 pounds, and for every pound it costs 0.75 dollars.
We can multiply the 2.1 by the 0.75 to find our answer.
The easiest way to do this is multiply the two numbers on 2.1 seperatly:
2 * 0.75 = 1.5
0.1 * 0.75 = 0.075
Then add them together:
1.5 + 0.075 = 1.575
Now we can round this to the nearest cent(hundreths place), and since the thousandths place is 5, we round up:
1.58
So our answer is $1.58!
Hope this helps!
Answer:
40
Step-by-step explanation:
Area is a squared measure of the one-to-one measure of the figures. If the surface areas of the figures, from smaller to larger, are 36 and 49, by taking the square roots of those numbers, you get the perimeter measure of the figures, which is the one-to-one measure. The square root of 36 is 6, and the square root of 49 is 7. Now, in order to find the ratio of the volumes smaller to larger, we take that one-to-one measure and cube it, since volume is a cubed measure. We will set up the proportions to find the cubed measures first. My proportion will be set up with the smaller figure's info on top and the larger figure's info on bottom: 
. Those are the cubed ratios. Now we will set up our equation to solve for the volume of the larger: 
. Now we can cross-multiply to solve for x, the volume of the larger figure. 216x = 222264. Dividing both sides by 216 gives us a volume for the larger figure of 1029 inches cubed. There you go!

Step-by-step explanation:
Total number of cards in the deck = 52
Number of clubs = 13
Number of picture cards = 12
Number of picture cards that are clubs = 3
So, number of picture cards or clubs = 
P(club or picture) = 
The answer is .
