Answer:
Answer:1200
Step-by-step explanation:
Consider the cost price to be x.
1st equation x - (15/100)x = x + (20/100) ...15% discount and gain of 20%
2nd equationx - (25/100)x = x + 120 ....25% discount and a gain of 120Rs
Solving above equations by subtracting we get
(10/100)x = (20/100)x - 120
Solving LHS and RHS..(10/100)x =120
x=1200

The volume of the oil is 18.0864 that is filled at a rate of $22 then the cost to fill the drum of oil is $397.9.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
What is a cylinder?A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
Given
A drum of oil has a height of 4 feet and a radius of 1.2 feet.
The oil costs $22 per cubic foot.
We know the volume of the cylinder
[tex]\rm Volume = \pi r^2h\\\\Volume = \pi *1.2^2 * 4\\\\Volume = 3.14 *1.44*4\\\\Volume = 18.0864[/tex]
The cost to fill the drum of oil will be
cost to fill the drum of oil = 22 x 18.0864
cost to fill the drum of oil = 397.9
Thus, The cost to fill the drum of oil is $397.9.

Isaiah is jogging near his college. He runs south along Capitol Street for about 0. 75 miles and east along H Street for about 1. 2 miles. He then turns left and runs along Florida Avenue until he reaches his starting point. How long is his total run to the nearest hundredth of a mile? A triangle. The sides are Capitol Street, H Street, and they hypotenuse is Florida Avenue. 2. 89 miles 3. 37 miles 3. 67 miles 3. 92 miles.
Answer:
His total run is approximately 3.37 miles.
Step-by-step explanation:
Let F represents his starting point, C represents his position from where he went to east direction and H represents his position from where he went to left towards Florida Avenue.
Thus, according to the question,
FC = 0.75 miles,
CH = 1.2 miles,
By making the diagram,
∠FCH = 90°,
By Pythagoras theorem:
Hence, the total distance he covered = FC + CH + FH
= 0.75 + 1.2 + √2.0025
= 3.36509716981
≈ 3.37 miles.

Is it possible to write a polynomial of degree 3 with zeros at 5, 3 and 8i? Explain your reasoning.
Answer:
No
Step-by-step explanation:
Because if 8i is a zero then -8i is also a zero. That means you now have four zeros, so the function is at least a fourth degree (quartic) function.
It is not possible to write a polynomial of degree 3 with zeros 5, 3 and 8i.
What is degree of polynomial?
A polynomial’s degree is the highest or the greatest power of a variable in a polynomial equation.
The degree of a polynomial is equal to the real zeros of the polynomial. Real zeros of the polynomial are 5 and 3 only. 8i is a complex number. Thus degree of the polynomial is 2.

Elliot makes and sells key chains. His profit depends on what price he charges for a key chain. He writes the expression (1 - 10) (60 - 3x) to represent his profit based on the price per key chain, I. Profit (S) 40+ 20+ Use the drop-down menus to complete the statements about Elliot's profit.
Using the vertex of the quadratic function, it is found that his maximum profit is of $75 when he charges $15 for a key-chain.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, the function is:
[tex]f(x) = (x - 10)(60 - 3x)[/tex]
In standard format, it is given by:
[tex]f(x) = -3x^2 + 90x - 600[/tex]
Which means that it's coefficients are a = -3, b = 90, c = -600.
Hence:
[tex]x_v = -\frac{90}{2(-3)} = 15[/tex]
[tex]y_v = -\frac{90^2 - 4(-3)(-600)}{4(-3)} = 75[/tex]
Hence, his maximum profit is of $75 when he charges $15 for a key-chain.
