Which Angel number supplementary to angel to AED
Answer:
Angle number 5
Step-by-step explanation:
The sum of supplementary angles equal 180°.
Angle AED, in the diagram given is labelled angle 4.
The angle labelled 4 forms a linear pair with the angle labelled 5.
Since a linear pair of angles = 180°, therefore:
m<AED + m<AEI = 180°.
That is:
m<4 + m<5 = 180°.
Both angles are supplementary.
Therefore, angle number 5 is supplementary to angle AED.

The required measure of the indicated angle b is 101°.
Use the concept of a triangle is defined as:
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
In the given figure,
Interior angle = 79°
And the corresponding exterior angle = b
If we combine both angles,
Then it becomes a complete angle of the line.
Since we know that,
The complete angle of a line = 180 degrees.
Therefore,
79° + b = 180°
Subtract 79° on both sides,
b = 101°
Hence,
The measure of angle b is 101°.

The length of a rctangle is to more than the
width. The perimeter of the rectangle is 72 meters
What is the length of the rectangle?
Answer:
19 m
Step-by-step explanation:
The width is 2 less than the length, so the perimeter is ...
P = 2(L +W)
72 = 2(L +(L -2))
76 = 4L . . . . . . . . add 4
19 = L
The length of the rectangle is 19 meters.

This is because rational numbers don't continue as a decimal infinitely
the sum of 3 consecutive integers is -69. Find the largest
x = the first integer
x + 1 = the second integer
x + 2 = the third integer.
Let's set each of our variables equal to -69
x + x + 1 + x + 2 = -69
Combine like terms
3x + 3 = -69
Subtract 3 from both sides.
3x = -72
Divide both sides by 3
x = -24
The first integer = x = -24
The second integer = x + 1 = -24 + 1 = -23
The third Integer = x + 2 = -24 + 2 = -22

Sarah has $400 in a savings account at the beginning of the summer. She wants to have more than $150 left in her account by the end of the summer. She withdraws $25 per week. How many weeks can she withdraw money from her account and still make her goal? Write an inequality to express the situation
Answer:
10 weeks; x >= $150
Step-by-step explanation:
400 - 150 = 250
She can only withdraw up to 250.
250 = 25w
250/25 = w
10 = w

What is N equal to? I think I know I want to make sure tho :/
Answer:
n = 5/7 or 0.7
Step-by-step explanation:
The goal is to isolate the variable N. First, you distribute the fractions to their repsective parentheses.
1/2(5n + 8) = 3/4(12 - 6n)
2.5n + 4 = 9 - 4.5n
2.5n + 4.5n = 9 - 4
7n = 5
Divide both sides by 7, and you get n = 5/7 or 0.7
Which has a larger value: 4 x 10^2 or 7 x 10^4?
Answer:
7 x 10^4
Step-by-step explanation:
4 x 10^2 equals to 400, when 7 x 10^4 equals to 70,000
Answer:
[tex]7[/tex]× [tex]10^{4}[/tex]
Step-by-step explanation:
Because the exponent means that the number is being multiplied by itself that many times. Like [tex]10^{4}[/tex] means 10000 and that times 7 is 70000.
[tex]10^{2}[/tex] would be 100 and 100 times 4 is 400. Now to determine is 400 or 70000 larger? 70000 is larger.
Hope that helps and have a great day!
12. Venu and Tanuj are running along a circular track. They take 48 seconds and 56 seconds to
complete a lap respectively. They begin from the starting point at the same time
6) How long does it take for them to meet at the starting point again?
How many laps will each boy have run by then?
Answer:
The meet at first time at starting point after 336 seconds,
Vanu have completed 7 laps while Tanuj has completed 6 laps.
Step-by-step explanation:
Given that Venu and Tanuj take 48 seconds and 56 seconds to
complete a lap respectively.
To meet them again at the startiong point, the time taken must be multiple of 56 and 48.
So, the minimum time required to meet them again at the startiong point is time taken for first time meet.
Time taken to first time meet is the smallest number which can be divided by 56 and 48, i.e the lowest common factor (LCM) of 56 and 48 which is 336 seconds or 5 minutes 36 seconds.
Number of laps by Venu
[tex]=\frac{336}{48}=7[/tex]
Number of laps by Tanuj
[tex]=\frac{336}{56}=6[/tex]

Answer:
7 weeks
Step-by-step explanation:
Joey gets 17 per week
[tex]17x[/tex] with x the number of weeks
he wants to buy a basketball cap that 43.67
[tex]equation\geq 43.67[/tex]
he has already saved 22.22

Solve for x and y: 10x=5y+5 y=2x-1
Answer:
So there are infinite solutions along the line y = 2x-1
Step-by-step explanation:
10x=5y+5
y=2x-1
Substitute y into the first equation
10x = 5(2x-1) +5
10x = 10x-5+5
10x = 10x
This is always true
So there are infinite solutions along the line y = 2x-1

Answer:
-3(4a+3)+4(6x+1)
12a+(-9)+24x+5
12a-4+24x
Step-by-step explanation:
Because you can't add 12a & 24x bc they're different variables ( a & x ) & -9+5 you always minus it and it's going to be a negative because -9 is bigger than 5

4. GROCERIES A local grocery store sells grapes for $1.99 per pound. Determine whether the function that models the
cost of grapes is discrete, continuous, or neither discrete nor continuous. Then state the domain and range of the
function.
Answer:
Ok, we know that the price, per pond of grapes, is $1.99.
Now the function that models the cost of grapes is:
C(x) = $1.99*x
Where x is the number of pounds that you buy.
Here we can assume two things:
1) The grapes are already in bags, so x can be only whole numbers, as x can take only whole numbers, the cost c(x) will be discrete because there are a lot of possible costs that are not accessible.
Then the domain is:
D: {0, 1, 2, 3, 4.....}
And the range is :
R: {0*$1.99. 1*$1.99, 2*$1.99, ...}
2)You can choose any amount of grapes that you want, and then the grapes are weighted when yo pay. (This has not really sense, but it is fun to analyze the problem in different ways)
Here the weight can take almost any value, because with individual grapes you can have almost any number of pounds.
But the unit that defines the total weight is the weight of a single grape.
Then if you have N grapes (and all of them weight almost the same, let's say M)
The total weight will e N*M
If you add one more grape, the weight is: (N + 1)*M
Then it is still discrete!
As we do not know the mean weight of a grape, we can not find the domain nor the range in this situation, so the one above is the one that we should consider the correct one.

\small \overrightarrow{QS} bisects \small \angle PQR. If \small m\angle PQS=5x-11 and \small m\angle RQS=3x+7, than what is \small m\angle PQR? \small m\angle PQR= 8x-4 degrees
Answer:
[tex] m\angle PQR =(8x - 4)\degree[/tex]
Step-by-step explanation:
Since, QS bisects angle PQR.
Therefore,
[tex]m\angle PQR = m\angle PQS = m\angle RQS\\
m\angle PQR =5x - 11 + 3x +7\\
m\angle PQR =5x + 3x + 7 - 11\\
