After manipulating above equation we get, 2x^2 - 7x - 8= 0. Discriminant= b^2 - 4ac = (-7)^2 - 4(2)(-8) = 113>0. So there are 2 real roots :)
Answer:
Amount of people to serve x Serving Size = Size of ham
12 x 6.5 = ?
=78
Step-by-step explanation:
Looking for size ham chen should buy = ?
Amount of people to serve = 12
Serving Size = 6.5-ounce
Equation=
Amount of people to serve x Serving Size = Size of ham
12 x 6.5 = ?
=78
Answer: 27 candles.
Step-by-step explanation:
A rectangular prism has a volume calculated by length x width x height.
In this case, the candles have a volume of 220 cm³.
If the company used 5940 cm³ of wax, to find how many candles they made, you just divide them:
You get 27 candles.
Answer:
51 cm^2
Step-by-step explanation:
the formula for area of an icoselese triangle is
A = b * h / 2
h is a line from the angle where the 5 and 5 intersect to the middle of the third line
You can find h using the pythagoran theorm with the 5 being the hypotenuse and the a being half the third line
4^2 + b^2 = 5^2
16 + b^2 = 25
b = 3, so h = 3, so now
A = 8 * 3 / 2
A = 24 / 2
A = 12 cm^2
now we have the triangle, just multiply that by 2 (top and bottom)
12 * 2 = 24
sides
8 * 1.5 = 12
5 * 1.5 * 2 = 15
now add all of it
15 + 12 + 24 = 51
