Answer:
b = 30
Step-by-step explanation:
b - 1 + 8 = 37 (Given)
b + 7 = 37 (Simplify)
b + 7 - 7 = 37 - 7 (Subtract 7 on both sides)
b = 30 (Simplify)

Find the perimeter and area of the figure.
5 cm
The perimeter of the figure is
centimeters
The area of the figure is
square centimeters.
PS: I got it wrong and I need help :)
Answer:
The perimeter is 20 cm.
The area is 25 cm^2.
Step-by-step explanation:
The perimeter is the distance around the figure.
This is a square, so each side is the same length.
There are four sides, so
5 + 5 + 5 + 5 = 20 cm
The area of the figure is
s^2
where s is a side
so 5 * 5 = 25 cm^2
What letter stays the same when reflected over the x-axis
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.p explanation:

Step-by-step explanation:
n = 2006-11+1 = 1996
the sum A = 1996/2 × (11+2006)
= 2,012,996

Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle C?
Enter your answer in the box.
Answer:
C = 80
Step-by-step explanation:
A cyclic quadrilateral is one where all 4 vertices touch the circumference of a circle.
It has 1 interesting property that should concern you: <B + <D = 180 degrees.
3x - 59 + 2x - 1 = 180 Combine like terms
5x - 60 = 180 Add 60 to both sides.
5x = 180 + 60
5x = 240
x = 240/5
x = 48
Now go to 2x + 4.
x = 48
A = 2*48 + 4
A = 96 + 4
A = 100
So C = 180 - 100
C = 80

-5n-4(-7-4n)=36+7n
What is N?
Answer:
n=2
Step-by-step explanation:
-5n-4(-7-4n)=36+7n
Distribute
-5n +28 +16n = 36+7n
Combine like terms
11n +28 = 36+7n
Subtract 7n from each side
11n+28-7n = 36+7n-7n
4n+28 = 36
Subtract 28 from each side
4n+28-28 = 36-28
4n = 8
Divide by 4
4n/4 = 8/2
n=2

how many numbers are there between 256 and 789 that are divisible by 7
Answer:
76
Step-by-step explanation:
How many numbers are between 256 and 789 are divisible by 7 ?
Generalizing, we could look for a procedure that, given two integers A and B, with B>A , and a module M, tells us how many integers x, with A<=x<=B , are divisible by M.
a) let n1 be the lowest integer >=A such that n1 is divisible by M.
If n1>B , than not even n1 has the required properties and the output of the procedure is 0; otherwise, go to the next step.
n1 will be the first number of the sequence of numbers divisible by M.
b) let n2 be the highest integer <=B such that n2 is divisible by M.
Notice that it’s not possibile that n2<A , as you alway have the possibility n2=n1 .
n2 w
A simple way to think about this is by calculating the largest multiple of 7 less than 256 (let’s call it y) and the smallest multiple of 7 greater than 789 (let’s call it x). The answer is then all the multiples of 7 in between these two numbers, which can be represented by:
x−y7−1
Let’s do it:
252 is the largest number less than 256 divisible by 7. y = 252
791 is the smallest number greater than 789 that’s divisible by 7.
Thus, our answer is 113-36–1 = 76.
Note: we subtract 1 or else we would include the number on the top end of the range (in this case, 791).
Hope it helped you!!

- Judy wrote a check for $63, then made a deposit
of $ 110. What was the overall chang to her
Account.
Answer:
$47
Step-by-step explanation:
110-63=47
Answer:
+$47
Step-by-step explanation:
As you are calculating for change, assume that the bank account has $0.
Judy wrote a check for $63, or she withdrew $63:
0 - 63 = -63.
Next, she deposited $110, or she added $110:
-63 + 110 = 47
The over all change to her account is a net profit of +$47.

In a three-person tug-of-war, three ropes are tied at a point. Gary is pulling due East with a force of 650 Newtons, June is pulling due North with a force of 450 Newtons, and Levi is pulling the third rope. The knot in the middle is not moving. What is the magnitude of Levi's effort?
A) 34.7 Newtons
B) 55.3 Newtons
C) 550 Newtons
D) 790.6 Newtons
Answer:
Its D) 790.6
Step-by-step explanation:
All I can say is that I aced the test so.
The answer to the question what is the magnitude of Levi's effort is D 790.6 N
Since Gary is pulling due East with a force of 650 Newtons, June is pulling due North with a force of 450 Newtons, the force due to Levi will be equal to the resultant force from Gary and June.
Since both Gary and June pull due East and due North respectively and these directions are perpendicular to each other, their resultant force is
R = √[(650 N)² + (450 N)²]
R = √[422500 N² + 202500 N²]
R = √[625000 N²]
R = 790.57 N
R ≅ 790.6 N
Since the resultant force due to Gary and June is 790.6 N, this is equal to the magnitude of Levi's effort since the knot does not move.
So, the magnitude of Levi's effort is 790.6 N
So, the answer to the question what is the magnitude of Levi's effort is D 790.6 N
