Answers
2 1/3 + 1 2/3 = 4
2 + 1 = 3; 1/3 + 2/3 = 1
3 + 1 = 4
3 3/3 = 4
3 = 3; 3/3 = 1
3 + 1 = 4
Now, let's come up with a fraction that is equal to 4.
2 6/3
This answer works because we already have 2 as an integer, and 6/3 is 2.
2 + 2 = 4
Hope this helps!
remember
a=a
a/a=1 where a=a
a. 3+3/3=3+1=4
b. 2+2/5+2+2/5=2+2+2/5+2/5=4+2/5+2/5=4+4/5=4 and 4/5
c. 3+3/8+1+5/8=3+1+3/8+5/8=4+3/8+5/8=4+8/8=5+1=6

Answer:
D 20 *1.10 * 1.05
Step-by-step explanation:
We have 19.8 tons of wheat. That is close to 20 tons
We increase by 9.8 percent. 9.8% is close to 10%
When we increase, that is 100% of what we had plus the increase, so we multiply by 100 +10% or 110%. In decimal form that is 1.1
20 *1.10
Then the next year we increase by 5.1%. That is close to 5%
We have 100% plus the 5% or 105%, which in decimal form is 1.05
We multiply what we had (20 *1.10) by 1.05
20 *1.10 * 1.05
This is the total amount we have

The question is incomplete. Here is the complete question:
Samir is an expert marksman. When he takes aim at a particular target on the shooting range, there is a 0.95 probability that he will hit it. One day, Samir decides to attempt to hit 10 such targets in a row.
Assuming that Samir is equally likely to hit each of the 10 targets, what is the probability that he will miss at least one of them?
Answer:
40.13%
Step-by-step explanation:
Let 'A' be the event of not missing a target in 10 attempts.
Therefore, the complement of event 'A' is
Now, Samir is equally likely to hit each of the 10 targets. Therefore, probability of hitting each target each time is same and equal to 0.95.
Now,
We know that the sum of probability of an event and its complement is 1.
So,
Therefore, the probability of missing a target at least once in 10 attempts is 40.13%.

Answer:
For given isosceles triangle ΔMKL with MK≅ML, x=9; MK=48, KL=31, ML=48.
Explanation:
An isosceles triangle has two of its 3 sides congruent.
For given ΔMKL, MK is congruent to ML (MK ≅ ML); i.e. length of side MK is equal to length of the side ML.
Given:
MK=7x-15
KL=4x-5
ML=10x-42
Equating MK with ML, we get:
MK=ML
7x-15 = 10x-42
Taking all x terms to the right,
42-15 = 10x-7x
27 = 3x
x=9
To find measure of each side MK, ML and KL; substitute the value of x=9 in corresponding equations.
MK = 7x-15
= (7×9) - 15
= 63-15
= 48
KL = 4x-5
= (4×9)-5
= 36-5
= 31
ML = 10x-42
= (10×9)-42
= 90-42
= 48
Therefore, for given ΔMKL with MK≅ML, x=9; MK=48, KL=31, ML=48.

about "half-life" until you're sure you understand what it means.
"Half life"means the length of time it takes for half of the shaky atoms that
you started with to fall apart. If you start with 100 of them, then 50 of them
die in the first half-life. If you start with 2 million of them, then 1 million of
them die in the first half-life. If you start with 2 radioactive atoms, then
one or the other will decay during the first half-life.
In this problem, you started with 96 grams of radioactive chromium.
Half of it ... 48 grams ... decays away in the first half-life.
What happens after that ? Exactly the same thing.
You start the next half-life with 48 grams of radioactive chromium.
Half of that ... 24 grams ... decays away in the next half-life.
After two half-lifes, you have 1/4 of what you started with.
