In my opinion I think it 35
T - the time that Dennis spent exercising ( in hours );

1 hour - 800 : 4 = 200 calories
Answer: D ) C = 200 t
Answer:
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
Answer:
The length of each leg = 5 units
The length of the base = 4 units
Step-by-step explanation:
Isosceles Triangle is a triangle with any two sides of it in equal measure.
Perimeter of a triangle = SUM OF ALL SIDES
Now, Perimeter of the triangle = 14
Let length of each leg = a
So, the length of the other leg is also a.
And, the base of the triangle is a -1
Now, as perimeter is 14.
⇒a + a + (a -1) = 14
or, 3 a = 14 + 1
⇒ 3 a = 15, or a = 15/3 = 5
Hence, the length of each leg = 5
And the length of the base = (a -1) = (5-1) = 4 units
Volume of a cylinder is given by πr^2h
Volume of the cylindrical water cooler is π x (12/2)^2 x 15 = 3.14 x 36 x 15 = 1,695.6 in^3
Volume of water in the cylindrical cooler is 1,695.6 / 2 = 847.8 in^2
Number of drinking cups that can be filled from the cooler is 847.8/20.14 = 42 cups.
