Answer:
Answer 1: C = 2πr or C = πd
Answer 2: d = 9 feet
Answer 3: r = 4.5 feet
Step-by-step explanation:
Answer 1: C = 2πr or C = πd
Answer 2: 28.26 = πd
28.26 = 3.14(d)
28.26/3.14 = d
9 = d
Answer 3: r = d/2
r = 9/2
r = 4.5

Una persona hace un trabajo en 6 horas, una segunda hace el trabajo en 8 horas y una tercera hace el trabajo en 10 horas. Si las tres personas trabajan al mismo tiempo ¿Cuánto tiempo durarán haciendo el trabajo?
a) 1 16/47 horas.
b) 2 26/47 horas.
c) 3 1/47 horas.
d) 4 36/47 horas.
Answer:
b) [tex]2\dfrac{26}{47}\ \text{horas}[/tex]
Step-by-step explanation:
Tiempo necesario para completar el trabajo en primera persona = 6 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{6}[/tex]
Tiempo necesario para completar el trabajo por segunda persona = 8 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{8}[/tex]
Tiempo necesario para completar el trabajo por tercera persona = 10 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{10}[/tex]
El tiempo necesario para completar el trabajo juntos viene dado por
[tex]\dfrac{1}{\dfrac{1}{6}+\dfrac{1}{8}+\dfrac{1}{10}}=\dfrac{1}{\dfrac{47}{120}}\\ =\dfrac{120}{47}=2\dfrac{26}{47}\ \text{horas}[/tex]
El tiempo necesario para completar el trabajo juntos es [tex]2\dfrac{26}{47}\ \text{horas}[/tex].

Answer:
The moon equals 7
and the stars equal 4
Step-by-step explanation:
Equation 1:
(substitute the symbols for the numbers)
7 + 1 = 4 + 4 (<< This is correct, both sides equal 8)
Equation 2:
(again, substitute the symbols)
7 = 3 + 4

pls help question is on picture
Answer:
We know that a triangle has angles that equal to 180°
[tex]45 + x + 77 + x + 72 = 180 \\ 194 + 2x = 180 \\ 2x = 180 - 194 \\ 2x = - 14 \\ x = - 7[/tex]
A= x+72
=-7+72

Solve the following trigonometric equation:
Answer:
45, 135, 195 and 345degrees
Step-by-step explanation:
Solve the following trigonometric equation:
2sin^22x + sin2x - 1 = 0
Let P = sin2x
Substitute
2P^2 - P - 1 = 0
Factorize;
2P^2 - 2P+P - 1 = 0
2P(P-1)+1(P-1) = 0
(2P+1)(P-1) == 0
2P+1 = 0 and P -1 = 0
P = -1/2 and 1
Since P = sin2x
sin2x = 1
2x = arcsin1
2x = 90
x = 90/2
x = 45degrees
Since sin is positive in the second quadrant
x = 180 - 45
x = 135 degrees
sin2x = -1/2
2x = arcsin(-0.5)
2x = -30
x = -15
Since sin is negative in the third and 4th quadrant
x = 180 + 15 = 195
x = 360 - 15 = 345
Hence the value of x are 45, 135, 195 and 345degrees

Answer:
x+3x=90
90/4= 22.5
x-22.5
Answer:
22.5
Step-by-step explanation:
its a 90 degree angle
90=3x+x

Answer:
In the teaching of the Catholic Church, an indulgence is "a way to reduce the amount of punishment one has to undergo for sins"
Step-by-step explanation:
Indulgence is the action or fact of indulging. (in the Roman Catholic Church) a grant by the Pope of remission of the temporal punishment in purgatory still due for sins after absolution. The unrestricted sale of indulgences by pardoners was a widespread abuse during the later Middle Ages.
Indulgence sentence example. The indulgence accentuated the division between those who accepted and those who rejected it. German chocolates are my only indulgence . I went to a party last night, and there out of five ladies three were Roman Catholics and had the Pope's indulgence for doing woolwork on Sundays.

How many solutions exist for the given equation?
1/2(x + 12) = 4x-1
zero
one
two
infinitely many
Answer:
one
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] (x + 12) = 4x - 1 ( multiply through by 2 to clear the fraction )
x + 12 = 8x - 2 ( subtract x from both sides )
12 = 7x - 2 ( add 2 to both sides )
14 = 7x ( divide both sides by 7 )
2 = x
There is one solution to the equation, that is x = 2

answer this plzz bc im confused i dont know what to do
Answer:
(2, 3)
Step-by-step explanation:
What is the solution to the system of equations represented by these two lines?
The solution of a system is a point that the lines have. In other words, it is the point where the two lines intersect.
The lines intersect at (2, 3), so the answer is the last option.
There is also a more reliable method of solving. In order for the two lines to be equal, their equations (1.5x = y and y= -0.5x + 4) must be equal.
So,
1.5x = -0.5x + 4
Add 0.5x to both sides.
2x = 4
x = 2.
Now, find how much y must be when x equals two. (You can use either equation to do this)
y = 1.5 * 2
y = 3.
Thus, the coordinates are (2, 3).

A camera has a listed price of $833.99 before tax. If the sales tax rate is 8.5%, find the total cost of the camera with sales
tax included.
Round your answer to the nearest cent, as necessary.
Answer:
904.88
Step-by-step explanation:
8.5% of 833.99 is 70.88915
70.88915 + 833.99 = 904.87915
904.87915 rounded to the closest cent is 904.88

A bridge being designed will cross the river at a right angle. The equation of the left bank of the river is j = 2x+8. The center of the bridge will pass through (0,2). What is the equation of the line representing the bridge?
This is the same as y = -0.5x+2
==========================================================
Explanation:
Refer to the diagram below.
The blue line is the graph of y = 2x+8, which is the left bank of the river.
For now, ignore the y = (-1/2)x+2 in the diagram and pretend we don't know that just yet. The red line is the bridge and it's some linear equation in the form y = mx+b. We're told the bridge is perpendicular to the river, so the bridge must also be perpendicular to the riverbank.
The blue line has slope m = 2. Apply the negative reciprocal to this to end up with -1/2. This is the perpendicular slope, and the slope of the red line. Note how the two slopes (2 and -1/2) multiply to -1. Any two perpendicular lines will have their slopes multiply to -1, as long as neither line is vertical or horizontal.
Since we want the bridge to pass through (0,2), this must mean the y intercept is b = 2.
So with m = -1/2 and b = 2, we go from y = mx+b to y = (-1/2)x + 2 which is the equation of the bridge shown in red.
This is the same as y = -0.5x + 2 since -1/2 = -0.5
A herd of 14 horses has 3 white and some black horses. What is the ratio of
black horses to all horses?
Answer:
11:14
Step-by-step explanation:
to find the amount of black horse you need to subtract 3 from 14
14 - 3 = 11
then you put it together
in this case the black horses were mentioned before all the horses so it would be:
11:14
