C cuz if it opens down a is negative and also it’s a parabola so it’s quadratic
Answer:
B
Step-by-step explanation:
A rectangular door for a shed has a width of 42 in and a diagonal support of 94 in. The triangle formed by the rectangle's width (first leg), rectangle's length (second leg) and rectangle's diagonal (hypotenuse) is right triangle. By the Pythagorean theorem,
Thus,
Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25
Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450
Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420
The class earned more money in September and they earned $30 more than in October.
L= 3w
Perimeter form = 2(l+w)
2(3w + w) = 112
6w + 2w = 112
8w = 112
w= 14
The greatest possible value for w is 14
Hope this helps!
Answer:90minutes
Step-by-step explanation:
Speed=distance/time
Speed=40miles per hour, distance=60miles
40=60/t
Cross multiply
40t=60
Divide both sides by 40
40t/40=60/40
t=1.5 hour =90minutes
