Answer:
4 cm
Step-by-step explanation:
Take the 11 cm on the bottom and subtract the 7 cm right above it.
Imagine the bottom half of this shape as a rectangle, the bottom and top side are of the same length. The top side would have to be 11 cm in length as well, so just subtract 11-7 to get the missing part.
2/10 represents 20 percent, as 10 is 100% because it is the Max, so something like 4/10 would be considered 40%
y-y1 = m(x-x1)
y-2 = 7(x-1) point slope form
y-2 = 7x-7
add 2
y=7x-5 slope intercept form
Answer:
5 ft
Step-by-step explanation:
a square has all equal sides
Answer:
AB = 2*sqrt(5) or
AB = 4.47
Step-by-step explanation:
AB is the hypotenuse of a right triangle A and B and the corner where 2 and 4 meet.
The length of AB is governed by the Pythagorean Theorem.
AB^2 = x^2 + y^2 Substitute 2 and 4 for x and y
AB^2 = 2^2 + 4^2 Expand the right side
AB^2 = 4 + 16 Add the right side
AB^2 = 20 Take the square root of both sides
sqrt(AB^2) = sqrt(20)
Factor 20 = 2*2 *5
Rule: when taking the square root of a number the pairs can take 1 member of the pair outside the root sign and throw the other one a way.
AB = 2 * sqrt(5) One of the roots has been thrown away.
