Answer:
x = 18°
Step-by-step explanation:
∠AOB and ∠BOD form linear pair of angles, so they are supplementary, i.e., their sum is 180°.
130° + (2x + 14)° = 180°
=> 130° + 2x° + 14° = 180°
=> 2x° = 180° - 130° - 14°
=> 2x° = 36°
=> x = 36°/2°
=> x = 18°

The diameter of a circle is 21 inches. Find the area of the circle. (Use 22/7 as the approximation of pi.)
Step-by-step explanation:
Area of a circle is pi times r-square
[tex]\pi \: {r}^{2} [/tex]
So...
[tex] \frac{22}{7} \times \frac{21}{2} \times \frac{21}{2} = \frac{22 \times {21}^{2} }{28} [/tex]
Do the rest yourself, my calculator and pen are not handy. Sorry
Solve for x: 1/3(21-3x)=1/2(8-4x)
Answer:
x = -3
Step-by-step explanation:
[tex] \frac{1}{3} -(21 - 3x) = \frac{1}{2} (8 - 4x)[/tex]
[tex]21 - 3x = 3(4 - 2x)[/tex]
[tex]21 - 3 x = 12 - 6x[/tex]
[tex] - 3x + 6x = 12 - 21[/tex]
[tex]3x = - 9[/tex]
[tex]x = - 3[/tex]
does anyone have the answers for all?
Answer and Step-by-step explanation:
1-6
a.
What you can do is plug in 6 and start by doing the first machine first, then the second. If this doesn't work, do the second machine, then the first machine.
The order that works is second machine, then first machine.
Second Machine:
y = [tex](6)^{2} -6[/tex] = 36 - 6 = 30
Plug into first machine now.
First Machine:
y = [tex]\sqrt{(30) - 5} = \sqrt{25} = 5[/tex]
We see that the result is 5.
b. If we were to do the order of second machine, then first machine, we will never get a negative result (or -5 for that matter), due to the fact that you can't algebraically square root a negative number.
However, if we were to do the order of first machine, second machine, we can get a negative number. To get -5, we plug in 6 for x in the first machine, getting an answer of 1. We plug this into the second machine, getting 1^2 - 6, which results in -5.
1-7. The absolute value of a value is the positive version of that value.
a. |54| = 54
b. [tex]-|-7\frac{3}{5}|[/tex] = [tex]-7\frac{3}{5}[/tex]
c. |3| - |-1| = 3 - 1 = 2
d. |2.2 - 5.13| = |-2.93| = 2.93

b. The amount of squares on each side of the figure increases by 1.
c. There would be 1 square, because we know that the pattern is there is 2 squares added to the next figure, 1 at each end. If we go back a figure, we take away 2 squares.
1-9.
a. -42 - 17 = -59
b. 8 - (-9) = 8 + 9 = 17
c. 8(-9) = -72
d. -42 ÷ (-7) = 6
e. -2(-3)(-4) = 6(-4) = 24
f. -18 - 7 = -25
g. [tex](-5)^{2}[/tex] = 25
h. [tex]-5^{2} = -(5)^2 = -(25)[/tex] = -25
i. [tex]\sqrt{49}[/tex] = 7
1-10. x = 2 Plug 2 in for x, then solve.
a. y = 7 - 3(2) = 7 - 6 = 1
b. y = [tex](2)^2 -1[/tex] = 4 - 1 = 3
c. y = [tex]\frac{18}{2}[/tex] = 9

A new cars salesperson, sold an average of $59,699 per day for the first 4 days she worked. The next 11 days she worked, she sold an average of $49,221. How much did she sell on average per day over the entire time she worked??
Answer:
5,000
Step-by-step explanation:
Solve using a weighted average like so:
{ (6 days)($34,000) + (4 days)($45,000) }/(6 days + 4 days) = $38,400
It doesn't appear as if the correct answer is listed in the choices? You can tell from the information given that the answer must be between $34,000 & $45,000!

Please help: is the square root of -9 a whole number, integer, rational., or irrational?
Answer:
Step-by-step explanation:
None of the above.
It is a complex number. The sqrt(-9) is defined as 3i.
i is a definition brought into existence to represent the square root of -1. There is nothing at this level of math that you can point to and say this is the physical thing that is the square root (-1). It is just a math/physics definition.

smallest would be 5 since it is already above 4
You start at (-4, -5). You move up 5 units. Where do you end?
Answer:
-4,0
Step-by-step explanation:
Moving up 5 units means moving 5 positive units in the y axis.
-5 + 5 = 0.
Therefore, you end up in (-4,0)

0 less than or equal to theta less than 2pi
sin theta= 1/2
HELP QUICK PLEASE !!!
WILL GIVE BRAINLIEST !
Answer:
theta = 4.5642792103077898247
Step-by-step explanation:
0 <= theta < 2Pi sin(theta) = 1/2
so
2Pi sin(theta) = 1/2
Pi sin(theta) = 1/4
sin(theta) = 1/(4Pi)
sin(theta) = .0795774715459
theta = arcsin(.0795774715459) = 4.5642792103077898247
2x-ky=14 and 5x-2y=5
In the system above, k is a constant and x and y are variables For what values of k will the system of equations have no solution.
Answer:
Step-by-step explanation
In these type of questions we can use a trick to find answer
let's say we have two linear equation
1) ax+by+c=0
2)mx+ny+t=0
if a/m = b/e ≠ c/f that means we don't have any solution for these two equations ( that's because of analitic geometry)
so,
2x-ky-14=0
5x-2y-5=0
2/5=k/2≠14/5 k=5If k is 4/5, the system of equations will have no solution because the lines are parallel.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The system will have no solution if the two equations represent parallel lines, because parallel lines do not intersect.
To determine if the lines are parallel, we can compare the slopes of the two lines.
The slope of the first line is 2, since it is the coefficient of x when we solve for y:
2x - ky = 14
ky = 2x - 14
y = (2/k)x - 14/k
The slope of the second line is 5/2, since it is the coefficient of x when we solve for y:
5x - 2y = 5
2y = 5x - 5
y = (5/2)x - 5/2
Therefore, the two lines are parallel if the slopes are equal:
2/k = 5/2
4 = 5k
k = 4/5
So, if k = 4/5, the system of equations will have no solution because the lines are parallel.

Answer:
m = 5s - 4
Step-by-step explanation:
Man = m
Son = s
the mans age is 4 years less than 5 times his sons age
5 times his sons age is 5s
4 less than that is 5s - 4
The man's age is 5s - 4 or m = 5s - 4

Going from x = -6 to x = -1 is 5 units to the right. We move another 5 units to the right to go from x = -1 to x = 4 when arriving at its reflected location (4,3). The y coordinate stays the same the entire time.
