4)Which of the following would be a good estimate for -7.94 - 2.31?

-9
-5
-6
-10

Answers

Answer 1
Answer:


1) add.

for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3


2) subtract

for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3


3) change
for example 3 - (- 2) = 3 + 2


4) -10

the sum is -10.25, which is closest to -10

Answer 2
Answer:

Answer:

1) add

2) subtract

3) change

4) -10

0.2 as a whole number

Answers

Ummm there is no possible way to change 0.2 into a whole number but you can change it into a fraction by simply putting the number of the place it is in under it like this 2/10=0.2
The smallest whole number is ' 1 '.  

0.2 is only 20% of ' 1 '.

0.2 does not have what it takes to be a whole number.

Hope this helps :)

Is 11/15 less than 4/5?

Answers

you start by dividing them and turning them into decimals
11/15 = .73 repeating
4/5 = .8

So that is a yes/ 11/15 is less then 4/5
yes 11/15 is greater than 4/5 because if u divide u will find the answer

Polygon ABCDEFGH will be dilated by a scale factor of 3.4 with the origin as the center of dilation to produce polygon A'B'C'D'EFG'H'. What will the length of A'H' be?

Answers

Even though you didn't attach any options I bet you have the same that I write in your task. I am pretty sure that length of A'H' should be 6.8 units. Do hope it will help you.

Solution:

Polygon ABCDEFGH is  dilated by a scale factor of 3.4 with the origin as the center of dilation to produce polygon A'B'C'D'EFG'H'.

As, when a polygon is dilated , the two pre image and image are similar to each other.

Also, similar shapes have same ratio of their corresponding sides length.

→Pre image (Polygon ABCDEFGH) ~Image ( A'B'C'D'EFG'H').

Dilation factor >1, equal to 3.4.

(AB)/(A'B')=(BC)/(B'C')=(CD)/(C'D')=(DE)/(D'E')=(EF)/(E'F')=(FG)/(F'G')=(GH)/(G'H')=(AH)/(A'H')=(1)/(3.4)\n\n A'H'=3.4* AH

Length of segment A'H'=3.4 AH

The most famous irrational number is pi because it pops up in so many different situations. Probably the next most famous one is 'e', the base of natural logarithms. The square root of 2 is also right up there.

5 1/10 divided 6 2/5

Answers

So, first, to make things easier, you should convert these mixed fractions into improper fractions so it's easier to deal with later. The improper fractions will be 51/10 divided by 32/5. 

Since you're are dividing fractions, there is a rule when dividing fractions, you have to multiply the number by the reciprocal, meaning the second fraction needs to be flipped and the divide signs will turn into a multiply sign. It will be:

51/10 times 5/32

This is the time where you simply where you can:
51/2 times 1/32

After simplifying, you times the numerator together (the top number of the fraction) and the denominator (the bottom number of the fraction).
=51/64
