Find the perimeter of the diagram.
Answer:
D. 52cm
Step-by-step explanation:
The perimeter of a shape is the sum of all its sides.
Not all of the sides are labelled in the diagram. We are missing two sides which I labelled "x" and "y" in the photo below.
We assume all sides are either parallel or perpendicular to each other since they look mostly "straight".
Find the length of the side x:
This side is like the 14cm side, except it's shorter by 3cm at the top and 3cm at the bottom.
x = 14cm - 3cm - 3cm
x = 8cm
Find the length of the side y:
This side is the same length as the 7cm side already labelled at the top.
y = 7cm
Find the perimeter:
Add all of the sides together.
P = 14cm + 7cm + 7cm + 3cm + 3cm + 5cm + 5cm + 8cm
If you want, you can simplify to this equation since some numbers are repeated.
P = [ 2(7 + 3 + 5) + 14 + 8 ] cm
Either way, you get the same answer.
P = 52 cm
find the mean deviation of 1,2,3 and 4
Personal Communication Fees An Internet ,telephone, and cable TV package plan costs month 90$ each month .The Internet part the bill is 35$. The telephone bill is $14 Write the ratio of the Internet bill to the cable TV bill in three different ways
Answer:
internet : cable = 35 : (90 -35 -14)internet / cable = 35 / (55 -14)internet / cable = 35 ÷ 41Step-by-step explanation:
A proportion can be written a number of ways. Here, we're asked for a specific ratio. Ratios are generally written using a colon (:) or a division symbol (/ or ÷). Here, the cable bill must be computed from the amounts of the other portions of the bill. That computation lends itself to being written in different ways. The point of the exercise is unclear, so the desired 'three different ways' are also unclear.
__
If we assume that the cable TV portion of the bill is separable from the package, it can be written as ...
cable bill = $90 -35 -14 = $55 -14 = $41
So, the ratio of internet to cable bills can be written as any of ...
internet : cable = 35 : (90 -35 -14)
internet : cable = 35 : (55 -14)
internet : cable = 35 : 41
internet / cable = 35 / (90 -35 -14)
internet / cable = 35 / (55 -14)
internet / cable = 35 / 41
__
Of course, the computation of the cable bill can be accomplished other ways, so that expression could be any of
cable bill = 90 -49 = 76 -35
Then you could have ...
internet : cable = 35 : (90 -49)
internet / cable = 35 / (76 -35)
Find the slope of the line.
Answer:
Brainleist!
Step-by-step explanation:
first obvious thing is the line is positive
it goes up 3 over 2
so its 3/2
positive = 3/2
Bottle G and bottle H have the same length.
find the value of X.
please show your working...
THANKS for your helping✨✨
Answer:
x = 2
Step-by-step explanation:
The length of bottle G in cm is 5x + 12
The length of bottle H in cm is 3x + 16
The bottles are of equal length, so set them equal to each other to solve for x:
5x + 12 = 3x + 16
2x = 4
x = 2
Amy was looking at a table of conversions from meters to kilometers. The table showed that 2 kilometers are equivalent to 2,000 meters, How can she determine how many kilometers are equivalent to 8,000 meters? Explain.
Answer:
The answer is in the question! If 2km = 2000m then 8km = 8000m
Step-by-step explanation:
Answer:
Sample Response: Amy can multiply 2 by 4, because the number of meters was multiplied by 4 to get 8,000 meters. 1 kilometer is a 1,000 times bigger than 1 meter. She could also divide 8,000 by 1,000 to get 8 kilometers.

What is the distance between the two points (5, -2) and (-3, 8)?
Answer:
2√41 ≈ 12.81 units
Step-by-step explanation:
The distance between two points is conveniently found using the distance formula:
d = √((x2 -x2)^2 +(y2 -y1)^2)
d = √((-3-5)^2 +(8-(-2))^2) = √(64 +100) = 2√41 ≈ 12.81 . . . units
I need help with this ASAP!!!!!!!!! A=1/2πr² and its solving for pi/π
Answer:
2A/r²=π
Step-by-step explanation:
A=1/2πr²
Multiply each side by 2
2A=2*1/2πr²
2A=πr²
Divide each side by r^2
2A/r² = πr²/r²
2A/r²=π
how do I solve one step equations
Step-by-step explanation:
To solve one step equations you have to do the opposite of whatever operation is being performed on the variable so you have to get the variable by itself
The most important thing to remember is that whatever you do to one side of the equation, you have to do the same thing to the other side.

Easha has 3 less than 5 times the number of quarters (1)
that Isabelle has. Which expression shows the number of quarters Easha has?
a. 31 – 5
b. 51 - 3
c. 5 - 31
d. 3 – 51
The correct answer is B.
Explain WHY this the correct
answer, make sure to show your work PLEASE :)
Answer: b. 51 - 3
Step-by-step explanation:
Given, Easha has 3 less than 5 times the number of quarters (I) that Isabelle has.
Here I is the number of quarters that Isabelle has.
Then, as per given,
Number of quarters Easha has = 5 ( number of quarters that Isabelle has) -3
= 5I-3
Hence, the expression shows the number of quarters Easha has is "5I-3"
So the correct option is b.

Answer: 1/5
Step-by-step explanation: 2/5 - 1/5 = 1/5. So 1/5 more visitors saw the panda this month.
please help me and if I can I’ll help you but please I don’t get it!!
Step-by-step explanation:
To solve this problem, let's set up our equation to solve for x (time to travel 13 miles).
[tex]\frac{65}{1} =\frac{13}{x}[/tex]
We use this equation to find x. To solve, we divide 13 by 65 to get our answer.
13 ÷ 65 = 0.2
Our answer: 0.2 hours
PLEASE HELP ME IM REALLY CONFUSED :(
Answer:
∠abc=34°
∠dbc= 44°
Step-by-step explanation:
(5x+4)+(5x-6)=78
10x-2=78
10x=78+2
10x=80
x=8
put x in each equation
∠abc= 5x8-6
40-6
34°
78-34= ∠dbc
∠dbc= 44°
Find the length of AB to the nearest hundredth
Answer:
7.28
Step-by-step explanation:
It’s the hypotenuse of a right triangle, so we can use Pythagorean’s Theorem.
2²+7²=C²
4+49=c²
53=c²
c=7.28
Answer:
7.28 to the nearest hundredth.
Step-by-step explanation:
A is (-5, -4) and B is (-3,3)
The distance AB = √ [(-5 - (-3)^2 + (3 - (-4)^2]
= √(4 + 49)
=√53
= 7.2801

Can you combine 3x + 13y + 10? Why or Why not?
Answer: Nope.
Explanation: In order to combine like-terms, they must all have the same variable. In 3x + 13y + 10, none of them have the same variable, so therefore cannot be combined.
I do not understand.
x/5 + 1 = 7
x = 40
x = 5
x = 30
x = 35
Answer:
x = 30
Step-by-step explanation:
x/5 + 1 = 7
subtract 1 from each side
x/5 + 1-1 = 7-1
x/5 = 6
Multiply each side by 5
x/5 *5 = 6*5
x = 30

Evaluate the expression below for s = 4 and t = 6.
3st^2-s^2
Answer:
Hey there!
We have: [tex]3(4)(6)^2-4^2[/tex]
This simplifies to: 432-16, or 416
Let me know if this helps :)
Answer:
The answer is 416Step-by-step explanation:
3st² - s²
s = 4 , t = 6
Substitute these values into the above expression
That's
3(4)(6)² - 4²
12(36) - 16
= 432 - 16
= 416Hope this helps you
Somebody help me solve what is in the image
Answer:
√2 is approximately 1.4.
Step-by-step explanation:
Part E:
1.3 squared is 1.69.
1.4 squared is 1.96.
1.5 squared is 2.25.
√2 is not between 1.3 and 1.4 because 1.4 squared only reaches up to 1.96 and not 2.
√2 is between 1.4 and 1.5 because 1.4 squared is 1.96 while 1.5 squared is 2.25. The √2 will be somewhere between 1.4 between 1.5.
2 is closer to 1.96 (0.04 units) than 2.25 (0.25 units). Thus, √2 is approximately 1.4.

Find all numbers c [4,12] for which the derivative is equal to the slope of the secant line connecting the function endpoints. If there is more than one such number c, use a comma to separate your answers. Round to the nearest thousandth. If there is no such number c, type "does not exist" in the entry box.
Answer:
Step-by-step explanation:
[tex]f'(x) =\frac{1}{2\sqrt{x-3}}[/tex]
By MVT, there exist a number c on [4, 12] such that
[tex]f'(c) = \frac{f(12)-f(4)}{12-4}[/tex]
[tex]f(12) = 3, and, f(4) = 1, hence f'(c) = \frac{1}{4}[/tex]
therefore,
[tex]\frac{1}{2\sqrt{x-3}} = \frac{1}{4}[/tex]
Solve this equation, you have x =1.
However, this is out of the given interval. Hence does not exist

Examine the graph. Which statements are true about the function represented by the graph? Select all that apply.
The function decreases between −∞ and 0.
The function increases between −1 and ∞.
The function increases between −∞ and −1.
The function increases between −10 and ∞.
The function decreases between −∞ and −1.
Answer:
2 & 5 statement
Step-by-step explanation:
for this, you would need to look at the x values. statement 2 says the function is increasing between -1 and ∞. look at the graph and you can see that -1 to ∞ is increasing. same thing with -∞ and -1. the function decreases.
hope this helped :)
