What is 19% of 41?
(Simplify, no links)
Answer:
7.79
Step-by-step explanation:
19 percent of 41 is the same as 19 per hundred of 41. We can therefore make the following equation:
19/100 = X/41
To solve the equation above for X, you first switch the sides to get the X on the left side, then multiply each side by 41, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:
19/100 = X/41
X/41 = 19/100
X*41/41 = 19*41/100
X = 779/100
X = 7.79
The work above shows the long way to explain how to calculate 19 percent of 41 in order to give you a foundation and better understanding of how to calculate the percentage. In the future, you could use this simplified formula:
(Y * P)/100
In our problem "What is 19 percent of 41?", Y is 41 and P is 19:
(41 * 19)/100 = 7.79
And once again you see that the answer is 7.79.

3+x=2–3x how many solutions and the answer thank you
Answer:
[tex]1[/tex] solution
Step-by-step explanation:
Let's try to solve this and see where we get.
We can add 3x to both sides of the equation to get [tex]3+4x=2[/tex].
We can then subtract 3 from both sides of the equation to get [tex]4x=-1[/tex].
We lastly divide both sides of the equation by 4 to get [tex]x=-1/4[/tex].
Because all of our steps are reversible(for instance, when we divide by 4, we can multiply(the "reverse" of division) by 4, so dividing by 4 is reversible), there is only [tex]\boxed{1}[/tex] solution, [tex]x=-1/4[/tex].

Point A is (2, -3) Use each transformation rule to find the coordinates of A’. Final answer in ( )
(x,y) ---->(x +3, y-1) A’=_________________________
(x,y) ----> (x, y-4) A’ = ________________________
By transformation rules, the points A₁(x, y) = (5, - 4) and A₂(x, y) = (2, - 7) are images of point A(x, y) = (2, - 3)
How to obtain the image of a point by a vector
In this problem we must determine two images associated to a given point and that are result of an transformation rule known as a translation. This transformation rule is described below:
A'(x, y) = A(x, y) + T(x, y)
Where:
A(x, y) - Original point.A'(x, y) - Image of the point.T(x, y) - Translation vector.First, write the coordinates of the original point:
A(x, y) = (2, - 3)
Second, find the images of the original point by transformation rule:
A₁(x, y) = (2, - 3) + (3, - 1)
A₁(x, y) = (5, - 4)
A₂(x, y) = (2, - 3) + (0, - 4)
A₂(x, y) = (2, - 7)

Terry’s average driving speed for a 2 and a half hour trip was 58 mph. How far did Terry travel?
145 miles. lets see how i got this.
so first i took the 2.5 hour trip and the average speed, which was 58 mph (or 93.3 kph), and multiplied them together, because of the rule of d=rt.
sidenote: also if you want to find the speed, use r=d/t. also, for finding the time, use the t=d/r rule.
side-sidenote: i hope this answers your question and helps you in the future.
key: r= rate (mph or kph), d=distance, and t=time.

The formula for the volume, V, of a sphere with radius r is V=(43)πr3. If the radius of a baseball is 113 inches, what is the volume to the nearest cubic inch?
A. 6
B. 8
C. 10
D. 14
15
The volume of the baseball, to the nearest cubic inch, is A. 6 inches³
The volume of a sphere is calculated by the formula:
= 4/3 x π x radius ³
A baseball is a sphere and in this case its radius is 1.13 inches.
The volume of the baseball is:
= 4/3 x 22/7 x 1.13³
= 4/3 x 22/7 x 1.442897
= 6.0464 inches³
To the nearest inch it is:
= 6 inches ³
In conclusion, the volume of the baseball is 6 inches.
