Answer:
$110
Step-by-step explanation:
we know
selling price = cost price + profit.
given
selling price of TV = $121
profit = 10%of cost
selling price of TV = cost of TV + 10%cost of TV
121 = cost of TV + 10/100 cost of TV
=> 121 = (100 cost of TV + 10 cost of TV)/100
=> 121*100 = 110 cost of TV
=> cost of TV = 121*100/110 = 110
Thus, cost price of TV is $110(option A)
Answer:
The volume is 140 cm3. See the explanation below, please
Step-by-step explanation:
We use the formula:
Volume (V) = 4/3 pi r ^3
V= 4/3x 3, 14x (6,44/2)^3 = 139,8 cm3= 140 cm3
Answer:
The answer is 7(tan 50°)
Step-by-step explanation:
So first you need to find which formula you will be using to do this you need to find if you're talking about the hypotenuse, opposite, or adjacent.
The side that measures 7 meters would be the adjacent because its right next to the angle and its not the hypotenuse because its not the largest side
The side which we do not know the length to will be the opposite side because it is opposite from where the angle is.
There are 3 formulas:
sin A = Opposite side/Hypotenuse = BC/AB
cos A = Adjacent side/Hypotenuse = AC/AB
tan A = Opposite side/Adjacent side = BC/AC
There is one formula that has Opposite and Adjacent which is tangent so thats the formula you'll use
Next you plug in the values that you have so your formula will look like this:
Tan 50° = x/7
A will always be where you plug in the angle and then you plug in the information according to what side it is
Every time that x is the numerator you will just multiply both sides by the denominator which gives you:
7(tan 50°)
Which is your answer :))
Answer: hi im mongraal
Step-by-step explanation:
In mathematics, a cube root of a number x is a number y such that y³ = x. All nonzero real numbers, have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8, denoted ³√8, is 2, because 2³ = 8, while the other cube roots of 8 are −1 + √3i and −1 − √3i. The three cube roots of −27i are 3i, 3√(3)/2-3/2i, and -3√(3)/2-3/2i.
Answer:
$17
Step-by-step explanation:
This is simply stated as a function.
We can rewrite this problem out as --> f(d) = -d + 42
If we simply say that he spent d, the problem states that d is equivalent to 25.
So the function looks like this --> f(d) = -25 + 42
Therefore your answer becomes --> f(d) = 17
