Answer:
2.) 7.8
Step-by-step explanation:
We can use Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 6^2 = c^2
25+36 = c^2
61 = c^2
Take the square root of each side
sqrt(61) = sqrt(c^2)
7.810249676 = c
Answer:
The answer is 10 minutes.
Step-by-step explanation:
First, convert the known amount of time to a fraction.
6/21 (min over hot dogs).
Set up a proportion.
6/21 = m/35 (m being the number of minutes)
Cross multiply.
210 = 21m
Solve for m. (divide each side by 21)
m = 10

Size of the painting: A * B
Scale factor: 1/3
Size of the photo: [1/3]A * [1/3]B
[1/3]A = 13inches
A = 13inches * 3 = 39 inches
[1/3]B = 17 inches
B = 17 inces * 3 = 51 inches.
Answer: the size of the painting is 39 inches by 51 inches.
