Answer:
point slope, slope intercept form, and I think two point
7. the wall is 12 the ladder is 15 find the ground
this will make a right angle from the wall and the ground
a^2+b^2=c^2
12^2+b^2=15^2
144+b^2=225
-144 both sides
b^2=81
square root both sides
b=9 ft
8. area of square is s^2
s^2=81
square root both sides s=9cm
diagonal=
a^2+b^2=c^2
9^2+9^2=c^2
81+81=c^2
162=c^2
square root both sides
12.73cm is diagonal
9. a^2+b^2=c^2
a=9
b=12
c=
9^2+12^2=c^2
81+144=c^2
225=c^2
square root both sides
c=15km
As for this problem, it would be best to approach this with a ratio to ratio approach. This would then involve the equation with fractions which is the common conversion from ratios to easily solve the problems concerning these. The equation then would look somehow like this:
0.01 miles / 1 hour = x miles / 2.4 hours
The easiest way would be just to multiply the numerator, which is the miles, to 2.4. So when it is multiplied to the numerator, the equation then would turn to:
0.01 miles x 2.4 / 1 hour = x miles / 2.4 hours
0.024 miles would be the answer.
Answer:
The answer is 1, 3, and 5
Step-by-step explanation:
First, you have to solve the equation, making the mixed number fractions into improper fractions. You then get 7/3 x 3/14. You can cross cancel, and thus the equation on the top is equal to 1/2.
Solve the rest of them, the same way you did in the first, and you would get 1, 3, and 5.
