Janice estimate was that it was under by approximately 0.6
units to the actual length of the triangle as she was examining the given
triangle with an estimation that the longest side has a length of 25 units―if
it is a right triangle.
Answer:
option a (2,2,5)
Step-by-step explanation:
First we have to notice that it tells us that the scale is 1/5.
This means that the measures of the new triangle will be 5 times smaller than those of the other triangle.
Now we just have to take the measurements of the sides of the triangle and multiply them by 1/5 or divide them by 5
AB = 10 DE = 10/5 = 2
BC = 10 EF = 10/5 = 2
AC = 25 DF = 25/5 = 5
DE = 2
EF = 2
DF = 5
(2, 2, 5)
Answer:
A) x + 2 ≤ 3
Step-by-step explanation:
To solve for this, you subtract 2 from both sides leaving you with:
x ≤ 1
which is what the graph is showing.
ANSWER: 46.8
39% of 120
The word "of" means multiplied. So you will have to multiply 39% x 120
To do that, first step is to change the percent (39%) into a decimal
39% = 0.39 (You move the decimal twice to the left, not right)
There's an invisible decimal behind 9 so ALWAYS move it twice.
= 39(.)⇒ 0.39
Then your final step is to multiply
120 x 0.39
1 2 0
x 0 . 3 9 ← notice this decimal
_______ ∨
1 0 8 0 ∨
+ 3 6 0 0 ∨
_______ ∨
4 6 8 0 There's an invisible decimal before the 0. Move that decimal two times to the left. 4680(.)⇒ 46.8
Answer:
Area = 3*3 + 3*4 = 9 + 12 = 21
