Why 1 hundred 4 tens and 14 tens name the same amount.

<span>Because 1 hundred contains 10 tens. So if you are saying 1 hundred and 4 tens it is the same as you would say 10 tens and 4 tens. And if you add them together 10 tens plus 4 tens it will be 14 tens together.</span>

First you need to translate these words mathematically as follows:

1 hundred = 100,

1 ten = 10,

2 tens = 2*10 = 20,

3 tens = 3 * 10 = 30,

4 tens = 4 * 10 = 40,

.

.

10 tens = 10 * 10 = 100

We can express 1 hundred 4 tens and 14 tens as follows:

1 hundred 4 tens = 1 hundred + 4 tens = 100 + 40 = 140 --- (1)

14 tens = 14 * 10 = 140 --- (2)

As (1) = (2), therefore, we can say that 1 hundred 4 tens and 14 tens yield the same amount (which is 140).

For question 7, if we add all votes for tiger and eagle, we get

tiger = 14 + 13 + 8 + 5 = 40
eagle = 6 + 7 + 12 + 15 = 40

so choices A and B are wrong.
C is also wrong because fifth and sixth grade votes for eagle are 6 + 7 = 13 and the 5th and 6th grade votes for tiger are 14 + 13 = 27. clearly 5th + 6th like tiger more.

D is the answer for question 7

question 8

rolling a cube does not affect the other cube so it is all independent probability.
cube: 1 2 3 4 5 6
3 even numbers and 3 odd numbers

so probability of rolling an even number is

1/6 + 1/6 + 1/6 = 3/6 = 1/2

multiplying by total number of rolls, she will get even numberss

300 * 1/2 = 150

about 150 time.
so half of the time, Cassie will roll and even number about half the number of rolls. never exactly since this is all probability. more likely for it to be around 150 times than exactly 150 time.

choice C is answer for question 8

Am i doing this right????

You are going in the right direction. For the distance of ST I get √136
√(-5-1)² + (6+4)² =
√(-6)² + (10²) =
√ 36 + 100 =
√136

√34² + √136² =√170²
34 + 136 = 170
170 = 170
