Answer:
A. $101/month
Step-by-step explanation:
From January to February, it changes by 195
From February to March, it changes by -72
From March to April, it changes by 180.
Now, you just find the average of these three numbers.
195 - 72 + 180 = 303
303 / 3 = 101
This means that the answer is A. $101/month
Write 19/4 as a decimal

AB is parallel to CD
Find the value of X
Find the value of Y
Answer:
∠y° = ∠69°
∠x = ∠69°
Step-by-step explanation:
1) The question relates to parallel line theorem
The given parameters are;
AB is parallel to CD
∠111° and ∠y° are consecutive interior angles
∠69° and ∠x° are alternate interior angles
When two parallel lines are crossed by a common transversal, the consecutive interior angles are supplementary (sum up to 180°), and the alternate interior angles are equal
Therefore, we have;
∠111° + ∠y° = 180°
∠y° = 180° - ∠111° = ∠69°
∠y° = ∠69°
2) For the alternate interior angles, ∠69° and ∠x°, we have;
Alternate angles are equal, therefore ∠x = ∠69°

Step-by-step explanation:
Find the radius: 6 ÷ 2 = 3m
Circumference = 2r with pi = 3cm x 3.14cm x 2 = 18.84m
Area = pi x 3cm x 3cm = 28.27m2
Calculate the circumference and area of given triangle.
Formula applied:Circumference of circle = 2πr
Area of circle = πr²
Solution:Radius,r = diameter/2 => 6/2 = 3 m
( i ) As we know that formula of circumference,
Circumference of circle = 2πr
[tex] \bf \: \star \: putting \: the \: values[/tex]

Which function's graph is shown below?
Answer:
B: y=sinx
Step-by-step explanation:
the parent sine function is a repeating function that goes from 0 to 1, with sin(0)=0 sin(pi/2)=1 sin(pi)=0 sin(3pi/2)=-1 and sin(2pi)=0, π≈3.1415926 and we see on this graph that the graph matches at all these major points.
the cosine parent function is essentially the same thing but shifted to the left by π/2. It is essential to familiarize yourself with the unit circle and the key angles and their respective sin and cosine values.
The answer is y = sin x!!

3. Find the slope and y-intercept of the graph of the following equation.
2y + 4 = -6x
Answer:
slope= -3,y - intercept y = -2
Step-by-step explanation:
- Make y the subject by taking four on the opposite side of the equal sign.
2y = -6x - 4
- Divide throughout by 2 and from there you get the gradient which is also the slope.
- To get the y - intercept,the value of x =0. Thus you get y =-2.

What is the apparent solution to the system of equations?
y = -2 +2
y=40 +7
Graph the system of equations using the Line tool. Plot a point at the apparent solution to the system using the point tool.
Answer:
y=−x+2y=4x+7 NO
y=−x+2 YES
y=4x+7
Multiply the first equation by 4, obtaining: 4y = -4x + 8
Add the 2nd equation to this result: y = 4x + 7
--------------------
5y = 15, and y = 3
Then, using the first equation, determine x:
y = 3 = -x + 2
1 = -x, so x = -1
The solution is (-1, 3)
Answer: (-1; 3)
Step-by-step explanation:
y = -x + 2
y = 4x + 7
4x + 7 = -x + 2
4x + 7 + x - 7 = - x + 2 + x - 7
5x = - 5
x = - 1
y = 4(-1) + 7
y = 3
Intersection point: (-1; 3)

Find a pair of numbers that have a sum of −3 and a difference of −7.
Answer:
x = -5 and y = 2
Step-by-step explanation:
You want to start by writing these two equations:
x + y = -3
and
x - y = -7
Then, you want to add the solutions to these two equations, like so:
-3 + -7 = -10
Then, to find the x value, because x > y, divide the answer by two:
-10/2 = -5
So, the x value is -5.
With this information, you can figure out that the y value is 2.
Check the answer:
-5 + 2 = -3
-5 - 2 = -7

It takes 900 pounds of steel to make one steel beam. How many beams can be made from 6,300 pounds of steel?
Answer:
7
Step-by-step explanation:
6,300 divide by 900 would equal 7
Answer:
7 beams
Step-by-step explanation:
To find how many beams can be made from steel, we have to find how many times 900 goes into 6,300. So our equation is:
6,300 ÷ 900 = 7
So you can make 7 beams out of 6,300 pounds of steel (and you won't have any steel left.)

Answer:
1. 12 2. 12 3.1/8 4. 11 5. -15 6.-60 7.20 8.225
Step-by-step explanation:
Given that :
m=2 and n=16 , p = {1-6 =-5} then;
1. m+10 = 2+10 = 12
2. n-4 = 16-4 = 12
3. m / n = 2/16 = 1/8
4. 6m - 1 = 6*2 - 1 = 12 -1 = 11
5. 3p =3* -5 = -15
6.12 p = 12* -5 = -60
7. 12m-4 = 12*2 - 4 = 24 -4 =20
8. 9p² = 9*-5² = 9 * 25 = 225

Find the area of the triangle with A = 60°, b = 11 feet, and c = 8 feet. Round to the nearest tenth.
Answer:
41.25 ft^2
Step-by-step explanation:
Literally all you need to do is Pythagorean Theroem.
a = ?
b = 11ft
c = 8ft
a^2 + b^2 = c^2
a^2 + 11^2 = 8^2
a^2 + 121 = 64
64 - 121 = a^2
a = 7.5
Then area of a triangle formula is (bh)/2
(11 x 7.5)/2 = 41.25

A builder needed to buy one hundred fifty-four boards for his latest project. If the board he needs comes in packs of three, how many packets will he need to buy
Answer:
51.3 packets or 51 1/3 packers
Step-by-step explanation:
From the above question:
The board he needs comes in packs of three. This means
1 pack = 3 boards
Hence:
3 boards = 1 packet
154 boards = x
Cross Multiply
3x = 154
x = 154/3
x = 51.333333333 packets
Approximately = 51.3 packets or 51 1/3 packers
The builder will need to buy 51.3 packets or 51 1/3 packers
