Answer:
Let x be odd such that LCM {x,40} = 1400 .
Since 1400 = 23×52×7 , then
x ∈ {5m×7n∣(m,n) ∈ {0,1,2}×{0,1}} .
By testing these values, we find that x = 175 .
Answer:
B
Step-by-step explanation:
Answer:
The answer is A.
Step-by-step explanation:
Answer:
19.1 feet
Step-by-step explanation:
Length of the ladder = 20 feet
Distance from the ladder to the wall = 6 feet
Height of the ladder on the wall = x
x² + 6² = 20²
x² = 20² - 6²
x² = 364
x = 19.1 feet (Rounded to nearest tenth)
Answer:
center=(-7,5)
Step-by-step explanation:
The center form of the circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k).
you can find center by making equal to zero each term, then:
x+7 = 0
x=-7
y-5 = 0
y=5
then the center is (-7,5).
