Answer:
To find the scale factor, all you have to do is <em>divide a side value of one figure by its congruent side value on another figure. </em>
Step-by-step explanation:
To start:
- The values 15 and 10 are both for the same congreunt side --> EF and E'F'
- The values 4 and 6 are both for the same congreunt side --> DE and D'E'
- The values 4 and 6 are both for the same congreunt side --> DG and D'G'
- The values 8 and 12 are both for the same congreunt side --> FG and F'G'
So, to find the scale factor, all you have to do is divide the smaller congruent value from the larger congruent value.
Larger congruent value ÷ smaller congruent value = scale factor
15 ÷ 10 = scale factor
\____________________/
1.5
<h3>So, the scale factor is 1.5</h3>
To double check, we will use another congruent side to find the scale factor:
12 ÷ 8 = scale factor
1.5 = scale factor
<h3>So, the scale factor is most definitely 1.5</h3>
I hope this helps!

Any number ends with 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9
Given any number. The square of this number is the last digit of square of the original numbers units digit.
For example
23*23 ends with 9 (3*3=9)
149*149 ends with 1 (9*9=81)
2564*2564 ends with 6 (4*4=16)
and so on
so all the possible unit digits of a square number are {0, 1, 4, 5, 6, 9}
because:
0*0= 0 ; 1*1=1; 2*2=4; 3*3=9; 4*4=16; 5*5=25, 6*6=36; 7*7=49; 8*8=64, 9*9=81
Thus, the probability that the square of a number selected from any set of numbers being 7, is 0.
Answer: 0
Answer:
21.74 ft
Step-by-step explanation:
We use Cosine because we are dealing with the Adj and Hyp
Cos 85 = x/20
x = 20 Cos 85
x = 1.74 feet away from the base of the wall.
Since the ladder is 20 foot long, the total distance will be 1.74 + 20 = 21.74 ft
Answer:
<u>86°F</u>
Step-by-step explanation:
Simplify terms, then move the terms over so 'y' is by itself.
-7y-0.6=3.6-y
-0.6-3.6=-y+7y
-4.2=6y
y=-4.2/6
y= -0.7
