0.1y = 3x^2
divide each side by 0.1
y = 3x^2/0.1
factor the right side to get y = 30x^2
this can't be written in the form y = kx so y does not vary directly with x
so there is no constant of variation.
Answer:
Distance=520cm
Step-by-step explanation:
The solution is in the image
The ice cream cone consists of a semi-circle with a diameter of 10 cm and a triangle with a base of 10 cm and height of 12 cm.
The area of a semi-circle is half the area of a full circle, so we can find it by using:
If the diameter of the circle is 10 cm, then the radius is 5 cm. Plug in the known values:
or about 39.25
The area of a triangle is:
So we can plug in the known values to find the area to be:
When we add the areas of the two sections together, we get an exact answer of:
(60 + 12.5pi) cm^2
or about
99.25 cm^2
Answer:
1850 cents or $18.50
Step-by-step explanation:
50*8=400
3*35=105
5*269=1345 ($2.69 can be converted to 269 cents)
400+105+1345=1850
A² + b² = c²
a² + 7² = 25²
a² = 25² - 7²
a² = 576
a = 24
Answer: The height is 24 feet.
