You could use the Pythagorean theorem which is a squared +b squared= c squared
you know a and c
a=24
c=25
24 squared + x squared = 25 squared
576+x squared =625
subtract 576 from both sides
x squared = 49
square root x and 49
x=7
C is the answer
Answer:
B
Step-by-step explanation:
There are 12 inches in 1 feet, so
5 feet = 5 * 12 = 60 inch
6 feet = 6 * 12 = 72 inch
So, we can say most adult humans are between 60 to 72 inches tall
The model is 7 inches tall. So, from the answer choices, 7 * 10 = 70 [the number that is in between 60 to 72]. Thus we can take the model to be 1/10th of the original.
So the scale factor is 1/10, or option B
Y= 11-2x
Substitute in:
5x-2(11-2x)=-13
5x-22+4x=-13(combine like-terms)
9x-22=-13
9x=-13+22
9x=9
x=1
Answer:
Step-by-step explanation: (2,-3) & 9(4,3)
<u>Y2 - Y1</u>
X2 - X1
<u>3 - -3</u>
4 - 2
= <u>6</u>
