Answer:
x=100 if im correct
Step-by-step explanation:
15.
2500 X 15 = 37500
37500 ÷ 100 = 375
375 + 200 = 575
The answer is C.
16.
The easiest way to answer this question is by going through each answer one by one:
14:6 = 28:18
28 <span>÷ 14 = 2
</span>18 <span>÷ 6 = 3
</span>Since both numbers were multiplied by different numbers, we can establish that this is not a true proportion.
42:7 = 6:2
42 ÷ 7 = 6
7 ÷ 7 = 1
42:7 = 6:1
By dividing both numbers by the same number, we can establish that the answer is wrong.
2:3 = 3:2
This is obviously wrong. That is because, in ratios, the order counts. So the first 3 is more than the first 2, therefore the second number on the other side of the ratio should be more than the first.
3:5 = 12:20
12 <span>÷ 3 = 4
</span>20 <span>÷ 5 = 4
</span>Since both numbers were multiplied by the same number, this is a true proportion.
The answer is D.
There are four different ways to fold the square in half, however there are no different ways to fold the letter G.
A square has four symmetry lines.
Each symmetry line splits the square in half.
This indicates that the square can be folded into one half along any of its lines of symmetry.
As a result, there are four different methods to fold the square in half.
There is no symmetry line in the letter G.
This indicates the letter can't be folded such that the two parts are exactly aligned.
As a result, there are no methods to fold the letter G.
Answer:
Option A.
Step-by-step explanation:
we know that
The lateral area of a cone is equal to
we have
substitute and solve for l (slant height)
simplify
Answer:put a pt on the y on -2 then go down 3 and 2 right put another pt
Then from first pt go up 3 and 2 left
Now you have 3 pts look at picture
