There are a few properties that will take a little while to learn, so reading this once will not necessarily teach you what you need to know.
1) exponent property of multiplication:
a^b(a^c)=a^b+c; what this means is if you have two terms with the same base multiplied by each other, you can add their exponents. Say that I have 2(2), we know that any singular number is raised to the first power. Both twos are raised to the first power so 2(2) is also 2^1+1, or 2^2. Similarly 2^2(2^3)=2^2+3=2^5. However if the terms have different bases this rule DOES NOT APPLY. (Sorry for caps, I needed emphasis).
2) exponent property of division:
a^b/a^c=a^b-c; what this means is that if you have two terms with the same base divided by each other you can subtract their exponents. For example 2^3/2^2=2^3-2=2^1=2.
3) exponent property of um... craziness: a^b^c=a^b(c); for this rule of exponents b and c don’t have to be the same. For example, if we have 2^2^3, 2^2^3=2^2(3)=2^6.
There are a few more, so these take patience, time, and attention to detail. I hope this helps a bit.
Answer:
2.3 mL
Step-by-step explanation:
This is called finding the volume by displacement. By subtracting the final volume and the initial volume you can determine how much the volume changed when the object was added. That change in voulme represents the volume of the object, so in this case:\
14.5-12.2 = 2.3 mL
Answer:
She sold 10 pounds of peaches and 45pounds of grapes
Step-by-step explanation:
X= pounds of peaches
x+35=pounds of grapes
2x+4(x+35)=200
2x+4x+140=200
6x=200-140
6x=60
x=10
She sold 10 pounds of peaches and 45pounds of grapes. (Sorry, can’t help you graph it.)
1 Yes
2 No
3 No
Hope this helps
We exclude bases for lateral area, so there are 4 sides. Each area of each of the sides can be found by 3*5. so, we have (3*5)*4, which equals 60 square meters.
