x=9 because the triangle is equilateral which means every side is equal to 60. When you do the math you get 7x-3=60 which is 7x=63 and 63/7=9
Answer:
3 ft.
Step-by-step explanation:
When you imagine the sentence, it is a right angled triangle. In this case, it's a Pythagoras Theorem. The formula for it is:
a²(opposite) + b²(adjacent) = c²(hypotenuse)
The building is the opposite, the distance between the foot of the ladder and the building is the adjacent, while the ladder is the hypotenuse.
We have the measurements except for the adjacent. So it will be:
c² - a² = b²
5² - 4² = b²
25 - 16 = b²
9 = b²
√9 = b
b = 3 ft
The answer is 3 ft.

Answer:
a: 0.1%
b. No it does not
c. Probably for safety reasons
Step-by-step explanation:
for women: z = (55.9 - 63.9)/3.6 = -2.22
The p-value for z = -2.22 is 0.0132, so only 1.32% of women could walk through without bending
for men: z = (55.9 - 69.7)/3.6 = -3.83
The p-value for z = -3.83 is 0.001, so only 0.1% of men could walk through without bending
