Which expression finds the measure of an angle that is coterminal with a 126° angle?
Answer:
Therefore the expression that finds the coterminal angles is:
[tex]coterminal = 126\º \pm 360[/tex]
Step-by-step explanation:
Coterminal angles are angles that finish at the same line. Therefore in order to find the coterminal angles with 126º we need to add or subtract a angle of 360º. So the expressions are:
coterminal angle = 126º + 360º = 486º
coterminal angle = 126º - 360º = -234º
Therefore the expression that finds the coterminal angles is:
[tex]coterminal = 126\º \pm 360[/tex]
Answer:
126° + (720n)°, for any integer n or D on edge :)

Answer:
a. x = 61 degrees.
Step-by-step explanation:
By the External angle of a Triangle Theorem:
116 = 55 + x
x = 116 - 55
x = 61 degrees.
Answer:
a) 61
Step-by-step explanation:
The classic way to do this is to subtract 116 from 180, then adding that result to 55 and subtracting this second result from 180.
But another way that I have discovered is to subtract 55 from 116. You will get the same answer of 61.

Answer:
b) 40
Step-by-step explanation:
By angle sum property of a triangle:
[tex] x°+20°+120°=180°\\
x°+140°=180°\\
x°=180°-140°\\
x° = 40°\\
\huge \red {\boxed {\therefore x = 40}} [/tex]
Answer:
B)40°
Step-by-step explanation:
Sum of angles in a triangle =180°
120°+20°+x°=180°
140°+×°=180
Collect like terms
x°=180°-140°
x°=40°

Jakob was asked to write an equation and solve this problem. Max saved enough money to buy three tickets to a baseball game. If each ticket costs $18.75, how much money did Max save? Jakob’s work is shown below.
Answer:
$56.25
Step-by-step explanation:
We know that Max has just enough money to buy 3 tickets that each cost $18.75, so let's write the expression:
18.75 * 3
We just solve this by multiplication:
18.75 * 3 = $56.25
Max saved $56.25.
Answer:
$56.25
Step-by-step explanation:
His savings were equal to the cost of 3 tickets, therefore
Savings = 3 × 18.75
Savings = 56.25

Celia drank 2 3 liter of water Monday before going jogging. She drank 3 7 liter of water after her jog. How much water did Celia drink altogether? Write your answer as a mixed number.
Answer:
23/21 liters
Step-by-step explanation:
Celia drank
Before going jogging=2/3
After jogging=3/7
Total amount of water drank by Celia=2/3+3/7
L.C.M of the denominators 3 and 7 is 21
=14+9/21
=23/21
=1 2/21 liters
Answer: 23/21
Step-by-step explanation:
Litre of Water drank before jogging = 2/3
Litre of water drank after jogging = 3/7
The total amount of water drank altogether ;
2/3 + 3/7
The lowest common factor of 3 and 7 = 21
= (14 + 9)/21
= 23/21 litres
= 1 2/21 litres [1 whole number 2/21]

A soccer team orders 15 wooden pedestals to mount their brass trophies on. The design of each pedestal is shown below. The team is charged $0.12 per cubic inch of wood. What is the total cost of the order, rounded to the nearest dollar?
Answer:
$1193
Step-by-step explanation:
First we need to find the volume of one pedestal, that has a cylindrical part and a cubic part.
The volume of the cylindrical part is:
V1 = pi * r^2 * h
The radius is half the diameter, so r = 8/2 = 4 in. So the volume is:
V1 = pi * 4^2 * 3 = 48pi in3
The volume of the cubic part is:
V2 = side^3 = 8^3 = 512 in3
So the total volume of the pedestal is:
V = V1 + V2 = 512 + 48pi in3
If we want 15 pedestals, we have a total volume of:
15 * V = 15 * (512 + 48pi) = 9941.9467 in3
As each cubic inch costs $0.12, we just need to multiply the volume by the price to find the total cost:
Cost = 9941.9467 * 0.12 = $1193.03
Rounding to the nearest dollar, we have a cost of $1193
Last question: What equation represents three less than five times a number is twelve?
A. 3 - 5x = 12
B. 5x - 3 = 12
C. 5(3 - x) = 12
D. 5(x - 3) = 12
Answer:
B, 5x - 3 = 12
Step-by-step explanation:
3 less means subtracting, it's going to be -3.
It says 3 less than five times a number, meaning we don't know the number, so we can put it as x.
3 less means your subtracting from something, which would make it 5x - 3.
Finally, they state that it equals 12, making the equation 5x - 3 = 12.

the sum of four consecutive integers is 34. find the least of the numbers
Answer:
7
Step-by-step
n=smallest integer; n+1=second integer; n+2=third integer; n+3=fourth integer
n+(n+1)+(n+2)+(n+3)=34
4n+6=34
4n=28
n=7 ANSWER: The smallest integer is 7
CHECK:
7+8+9+10=34
34=34
the least of the four consecutive integers is 7.
Let's denote the four consecutive integers as x, x + 1, x + 2, and x + 3.
According to the given information, the sum of these four consecutive integers is 34:
x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) = 34
Simplifying the equation:
4 x + 6 = 34
Subtracting 6 from both sides:
4 x = 28
Dividing both sides by 4:
x = 7
The four numbers are 7, 8, 9, 10
Therefore, the least of the four consecutive integers is 7.

Find the value of c (x-2) is a factor of the polynomial p(x). P(x)=x^3-4x^2+3x+c
Answer:
c = 2
Step-by-step explanation:
P(x)=x^3-4x^2+3x+c
The polynomial has x - 2 as a factor
Rewriting the polynomial as:
x^3-4x^2+3x+c = x^3 - 2x^2 - 2x^2 + 4x - x + c =x^2(x - 2) - 2x(x - 2) - (x - c)As we see the first 2 terms have (x -2) as a factor, so the third term:
(x - c) = (x - 2) c=2Answer is c= 2
What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?
Answer:
Step-by-step explanation:
if m is the slope of given line.
Then eq. of parallel line through (-4,-6) is
y+6=m(x+4)
Answer:
y=-6
Step-by-step explanation:
The line shown is a horizontal line through the y-axis and has the equation y=4. A parallel line to it is a line that does not cross it. It will also have the form y=a where a is the y-coordinate of its points. The point (-4,-6) is on the line so y=-6 is the line.
If 30% of the students taking a module failed the practical test. The class has 130 students. How many students passed the test?
Answer:
91 students passed the test.
Step-by-step explanation:
130 / 10 = 13
13 x 3 = 39
130 - 39 = 91
Answer:
91 students passed the test.
Step-by-step explanation:
We need to find 10% of 130.
130÷10=13
Then we need to make it 30% in order to see the amount of students that failed the test.
13×3=39
Then we need to do 130 - 39 (The whole class- 30%)
130-39=91

A rectangular prism has a base with a length of 25, a width of 9, and a height of 12. A second prism has a square base with a side of 15. If the volumes of the two prisms are equal, what is the height of the second prism?
picture is here
Answer:
Step-by-step explanation:
the volume of a rectangle is length x width x height, so the volume of the first rectangle is 2700.
the square has a length and width of 15 with a missing height. because they have the same volume, you can plug in the length and width of the square with the volume of the prism to find the height
v = length x width x height
2700 = (15)(15)h
2700/225 = h
the height is 12

Each interior angle of a regular polygon is 140°.Find the number of sides of the polygon.
Answer :
9 sides
Explanation:
Step 1
Since the interior angle is 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.
Step 2
Method 2: Since the exterior angle is 140°
The sum of the interior angles = (2n - 4) × right angles.
So 140n =(2n - 4) ×right angles, or we can also say
140n =(2n - 4) × 90
140n = 180n - 360
40n = 360
Divide both sides of the equation by 40
n = 9 sides.
n = 9 sides.Hence the number of sides is 9 sides.

f(x) = 4^x-1; find f(3)
Answer:
f(3) = 63
Step-by-step explanation:
f(x) = 4^x-1;
Let x =3
f(3) = 4^3 -1
= 64-1
=63
Answer:
f(3)=16
Step-by-step explanation:
This question asks us to find f(3). We have to find what f(x), or y is, when x is equal to 3.
f(x)=4^x-1
Substitute 3 in for x.
f(3)=4^3-1
First, subtract what is in the exponents.
f(3)=4^2
4^2 is the same as multiplying 4, 2 times.
4^2=4*4=16
f(3)=16
