Answer:
I think that it is B because its the only answer that makes sense
Step-by-step explanation:
Step-by-step explanation:
the area of a triangle
baseline × height / 2
in our case
baseline × height / 2 = 60 in²
height = 6×baseline - 16
baseline × (6×baseline - 16) / 2 = 60
baseline × (3×baseline - 8) = 60
3×baseline² - 8×baseline = 60
baseline = x
3x² - 8x - 60 = 0
general solution to a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 3
b = -8
c = -60
x = (8 ± sqrt(64 - 4×3×-60))/(2×3) =
= (8 ± sqrt(64 + 720))/6 = (8 ± sqrt(784))/6 =
= (8 ± 28)/6
x1 = (8 + 28)/6 = 36/6 = 6
x2 = (8 - 28)/6 = -20/6 = -10/3
x2 as a negative number is not a valid solution for a length in a geometric shape.
so, x = 6 in is our solution for the baseline.
height = 6x - 16 = 6×6 - 16 = 36 - 16 = 20 in
base = 6 in
Answer:
11.9375 and just round it
Step-by-step explanation:
multiply 8 pounds to 16 to get ounces and then add three and 60(5 x 12) and then add all of it together and then divide it to 16 to get 11.94 pounds or however you want to round it. If you need more a more deeper explanation just ask.
Answer:
150in²
Step-by-step explanation:
The surface area of a cube is given by the following equation where <em>s</em> is the length of a side:
So, in this case, s is equal to 5:
Answer:
Sofia went on a road trip to visit her family. She first traveled from West Palm Beach to Fort Myers which is 108 miles away. The next day, she drove to Miami for a distance of 135 miles. Finally, driving back home for 81 miles. Determine if the three towns on Sofia’s road trip form a right triangle. Which statement is correct?"
