Answer:
2.25 hours or 2 hours and 15 minutes
Step-by-step explanation:
Using the information from the bill shown in the question we can determine the number of hours spent by first subtracting the amount of money spent on parts from the overall total, which would leave us with the total amount spent on labor. Now we would simply divide this by $44 which is how much each hour of labor costs. Finally, this would leave us with the total number of hours of labor that the mechanic put into the car repair.
$384 - $285 = $99
$99 / 44 = 2.25 hours or 2 hours and 15 minutes (0.25 * 60 minutes)

The angle measurements that can form triangle ABC are
m∠A = 40°, m∠B = 75°, m∠C = 65°m∠A = 136°, m∠B = 28°, m∠C = 16°m∠A = 60°, m∠B = 60°, m∠C = 60°How to determine the angle measurements?The angle measurements that can form a triangle must add up to 180 degrees.
i.e. a + b + c = 180
Using the above formula, we have:
40 + 75 + 65 = 180
136 + 28 + 16 = 180
60 + 60 + 60 = 180
Other angles do not add up to 180.
Hence, the angle measurements that can form triangle ABC are
m∠A = 40°, m∠B = 75°, m∠C = 65°m∠A = 136°, m∠B = 28°, m∠C = 16°m∠A = 60°, m∠B = 60°, m∠C = 60°Read more about triangles at:

What is "a" if B=
is a singular matrix
| 2
2 a
Answer:
The value of a=4
Step-by-step explanation:
Given the matrix
[tex]B=\begin{pmatrix}1\:&\:2\:\\ \:\:\:2\:&\:a\end{pmatrix}[/tex]
A matrix is singular if its determinent is zero.
so solving the matrix B by taking its determinant to get the value a
[tex]\det \begin{pmatrix}1&2\\ 2&a\end{pmatrix}=0[/tex]
as according to determinant formula
[tex]\det \begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}\:=\:ad-bc[/tex]
[tex]1\cdot \:a-2\cdot \:2=0[/tex]
[tex]a-4=0[/tex]
[tex]a=4[/tex]
Therefore, the value of a=4
If (4,-3) is the midpoint of the line segment ST and the coordinates of S are (1,5), find the
coordinates of T.
Answer:
[tex](7,-11)[/tex]
Step-by-step explanation:
Given
[tex]S = (1,5)[/tex]
[tex]M = (4,-3)[/tex]
Required
Determine the coordinates of T
Midpoint is calculated as:
[tex]M(x,y) = \frac{1}{2}(x_1 +x_2,y_1+y_2)[/tex]
Where:
[tex](x,y) = (4,-3)[/tex]
[tex](x_1,y_1) = (1,5)[/tex]
Substitute these values in the above formula:
[tex](4,-3) = \frac{1}{2}(1 + x_2,5+y_2)[/tex]
Multiply through by 2
[tex]2 * (4,-3) = 2 * \frac{1}{2}(1 + x_2,5+y_2)[/tex]
[tex](8,-6) = (1 + x_2,5+y_2)[/tex]
By direct comparison:
[tex]1 + x_2 = 8[/tex] and [tex]5 + y_2 = -6[/tex]
Solving for x2
[tex]1 + x_2 = 8[/tex]
[tex]x_2 = 8 - 1[/tex]
[tex]x_2 = 7[/tex]
Solving for y2
[tex]5 + y_2 = -6[/tex]
[tex]y_2 = -6 - 5[/tex]
[tex]y_2 = -11[/tex]
Hence, the coordinates of T is: [tex](7,-11)[/tex]

a. [tex]1\leq x^2 + y^2 + z^2 \leq 25[/tex]
b. [tex]x^2 + y^2 + z^2 \leq 25, x \geq 0[/tex]
Answer:
(C).The solid ball of radius 5 centered at (0,0,0) with the interior of the solid ball of radius 1 centered at (0,0,0) removed.
Step-by-step explanation:
These are the equation of Spheres
In the equation [tex]1\leq x^2 + y^2 + z^2 \leq 25[/tex], when we will take square root of 25 we will get radius as 5 so the Sphere is varying from radius 1 to 5, Which will make it into a Solid sphere with the center at (0, 0, 0)
In the equation [tex]x^2 + y^2 + z^2 \leq 25, x \geq 0[/tex] it is given that the sphere is less than
radius 5 units.
Also there will be no sphere with radius from 0 to 1 because the sphere is starting from radius 1 and increasing till radius 5.
Therefore, The sphere is a solid increasing from radius 1 to 5.
and another solid sphere is removed from inside with radius increasing from 0 to 1.

how many squares do I have to draw in(10 x 10 grid) for the percentage of 57.74%??
Answer:
There is obviously only 1 10x10 square. If we start with a 9x9 square in the top left corner, we can move it down 1, across 1 and back up 1, so there are 4 possible 9x9 squares.
For 8x8 we can move down 1, then 2 and we can move across 1 or 2 so that's 9 possible 8x8 squares.
For 7x7 we can go down 3 and across 3, so that's 4x4=16 possible squares.
The pattern is now clear the total number if squares is 1+4+9+16+…+100.
There's a formula for this, which I had to look up, but any the sum of the first n squared is 1/6n(n+1)(2n+1)1/6n(n+1)(2n+1), so the total number of squares is 10x11x21/6=5x11x7=385.

The present value of the payments over three years is $1600000.
Given that, the prize of lottery money is $1 million.
What is the simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.
Now, P=$1,000,000, R=20% and T=3 years
So, S.I. = (1,000,000 × 20 × 3)/100
= 600000
Amount = 1,000,000+600000
= $1600000
Therefore, the present value of the payments over three years is $1600000.

What is the inverse of function f?
f(x)=64x^3-1
The inverse function of f(x) is:
[tex]g(x) = \sqrt[3]{(x +1)/64}[/tex]
How to find the inverse function?
Here we have the function:
[tex]f(x) = 64*x^3 -1[/tex]
We want to find the inverse, we will say that is of the form:
[tex]g(x) = \sqrt[3]{a*x + b}[/tex]
If we evaluate f(x) on g(x), we get:
[tex]f(g(x)) = 64*(\sqrt[3]{ax + b})^3 - 1\\ \\f(g(x)) = 64*(ax + b) - 1[/tex]
If these are inverses, that must be equal to x:
[tex]64*(ax + b) - 1 = x\\\\64*a*x + 64*b - 1 = x\\[/tex]
Then:
64*a = 1
a = 1/64
64*b - 1 = 0
b = 1/64
So the inverse function is:

Austin would like to bake 20 more identical cupcakes to ice each cupcake in the likeness of a playing-card. Does he have enough left to create 20 additional cupcakes? Explain.
9514 1404 393
Answer:
no
Step-by-step explanation:
We can write a proportion to find how much mix is required to make 52 cupcakes.
quarts/cupcakes = 3.5/32 = x/52
Multiplying by 52, we find ...
x = 52(3.5/32) = 5.6875 . . . quarts needed for 52 cupcakes
This is more mix than Austin made. He does not have enough left for 20 more cupcakes.
