Answer:

The new area of the similar figure would actually be 256 square centimeters. Want to know why it would by 256 and not 128 like you think and like the other answer says? That is because they are not saying the area is being doubled they are saying that the SIDES are being doubled. Therefore if the area was 64 then one side was 8. If you double 8 it is 16. Then the area of the new figure would be 16*16 or 16 squared which equals to 256 centimeters squared.

Answer:

read the explanation, i'm not gonna answer this one for you, but instead I want you to try this on your own.

Step-by-step explanation:

divide the 360 by each percentage, and if you dont know how to do that, there are videos out there, i <em>would</em> explain it <em>but </em>i dont have much time to write all of that. after you get each number from dividing 360 by each percentage <em>individually </em>you will add up the <u>needed</u> numbers. that will give you your answer! have a nice day :D

10.9 + (-15.6) + 2.1 write as a decimal​
Delvig [45]

Answer:

-2.6

Step-by-step explanation:

10.9 + (-15.6) becomes 10.9 - 15.6 which equals -4.7. The last step is to add the 2.1 to the -4.7: -4.7 + 2.1 = -2.6

Therefore the answer is -2.6

The sum of a two digit number and the number obtained by interchanging the digits is 132. If the two digits differ by 2, find th
damaskus [11]

Answer:

A two-digit number can be written as:

a*10 + b*1

Where a and b are single-digit numbers, and a ≠ 0.

We know that:

"The sum of a two-digit number and the number obtained by interchanging the digits is 132."

then:

a*10 + b*1 + (b*10 + a*1) = 132

And we also know that the digits differ by 2.

then:

a = b + 2

or

a =  b - 2

So let's solve this:

We start with the equation:

a*10 + b*1 + (b*10 + a*1) = 132

(a*10 + a) + (b*10 + b) = 132

a*11 + b*11 = 132

(a + b)*11 = 132

(a + b) = 132/11 = 12

Then:

a + b = 12

And remember that:

a = b + 2

or

a = b - 2

Then if we select the first one, we get:

a + b = 12

(b + 2) + b = 12

2*b + 2 = 12

2*b = 12 -2 = 10

b = 10/2 = 5

b = 5

then a = b + 2= 5 + 2 = 7

The number is 75.

And if we selected:

a = b - 2, we would get the number 57.

Both are valid solutions because we are changing the order of the digits, so is the same:

75 + 57

than

57 + 75.

124 - 67 = 57
142 - 96 = 46
272 - 119 = 153
261 - 95 = 166
225 - 88 = 137

p.s a calculator does exist.
