If the scale on a map shows 1 in. = 100 mi., and you determine that two cities are 5.5 in. apart, how many actual miles is this? Question 11 options: 55 mi. 550 mi. 0.005 mi. 5.5 mi.
Answer:
550 mi. !!!!
Step-by-step explanation:
Answer: 550 miles
Work Shown:
1 in = 100 mi
5.5*(1 in) = 5.5*(100 mi) ..... multiply both sides by 5.5
5.5 in = 550 mi

Answer:
The equation in y = mx+b form is y = (4/3)x - 20/3
The equation in Ax+By = C form is 4x - 3y = 20
There are other ways to express the second equation.
==============================================================
Explanation:
First we must complete the square for x and y.
This will get the equation into (x-h)^2+(y-k)^2 = r^2 form so we can determine the center.
x^2+y^2 - 8x-14y + 40 = 0
(x^2-8x) + (y^2-14y) + 40 = 0
(x^2-8x+16 - 16) + (y^2-14y+49-49) + 40 = 0
(x^2-8x+16) + (y^2-14y+49) + (-16-49+40) = 0
(x-4)^2 + (y-7)^2 = 25
(x-4)^2 + (y-7)^2 = 5^2
This circle is centered at (h,k) = (4,7) and it has radius r = 5.
----------------------
Next, we need to find the slope of line AB such that
A = (4,7) = center of the circle
B = (8,4) = point on the circle, which is the point of tangency
m = slope
m = (y2-y1)/(x2-x1)
m = (4-7)/(8-4)
m = -3/4
The slope of line AB is -3/4. Any perpendicular slope will have us do two things:
flip the fractionflip the signthat would get us from -3/4 to +4/3 or just 4/3.
The perpendicular slope is 4/3.
----------------------
So we must find the equation of the line with slope m = 4/3 and it goes through (x,y) = (8,4)
That means,
y = mx+b
4 = (4/3)*8 + b
4 = 32/3 + b
4 - 32/3 = b
12/3 - 32/3 = b
(12-32)/3 = b
-20/3 = b
b = -20/3
Therefore, the equation of the tangent line is y = (4/3)x - 20/3
Optionally, we can get this equation into standard form like so
y = (4/3)x - 20/3
3y = 4x - 20 ... multiply everything by 3
3y-4x = -20
-4x+3y = -20
4x - 3y = 20

4. A craft store offered sewing classes on 12 of the 30 days in November.
What decimal is equivalent to the fraction of days in Movember that classes were
offered at the restaurant?
A
0.4
C. 0.5
B.
0.6
D. 0.3
Answer:
A. 0.4
Step-by-step explanation:
Write 12 of 30 as a fraction:
12/30
Convert this to be a fraction over 100 by setting up an equation:
Variable x = proportional answer to 12/30
12/30 = x/100
Cross multiply:
12 × 100 = 30 × x
1200 = 30x
40 = x
40/100
Convert this number into a decimal by adding a zero and decimal point before the "4" in 40:
0.40
Simplify:
0.40 = 0.4
I converted it into a decimal through the use of fractions, but you can also find the answer by doing long division: 12 ÷ 30. However, showing work for long division over a message is too complex so I solved the problem this way instead.

(a) What is the maturity value of the loan?
Answer:

Step-by-step explanation:
So first, you need to multiply 7 by four to get the quarterly part of it, which will be 28. Then, multiply 9% (.9) by your 28 to get 25.2. Finally, multiply that by 7,000 to get 176,400...

2x =
(SOMEONE PLEASE ANSWER)
Answer:
x°=43°
2x°=86°
(x+8)°=51°
Step-by-step explanation:
x+2x+x+8=180°[being sum of the angles of triangle]
or, 4x+8=180
or, 4x=180-8
or, 4x=172
or, x=172/4
or, x=43°
Then,
2x=2×43°=86°
(x+8)°=(43+8)°=51°

through : (- 5, - 5); slope = 3/5
Answer: y + 5 = 3/5 (x + 5)
Concept:
There are four general forms of equations:
Slope-intercept form: y = mx + b Point-slope form: y - y₁ = m (x - x₁) Standard form: Ax + By = C Intercept form: x/a + y/b = 1Here, we are going to use the point-slope form because the question has given us both the slope and one point.
Solve:
**Disclaimer** Since the question did not clarify, thus, I choose to use the point-slope form as it is the easiest method. However, if the question has a specified form of the equation, please tell me and I will redo it.
Given information
(x₁, y₁) = (-5, -5)
m = 3/5
Given expression
y - y₁ = m (x - x₁)
Substitute values into the expression
y + 5 = 3/5 (x + 5)
Hope this helps!! :)

Solve for r: 3r+2-r=-4
Answer:
r = -3
Step-by-step explanation:
3r + 2 - r = -4
2r + 2 = -4
2r = -6
r = -3
Answer:
r = -3
Step-by-step explanation:
3r + 2 - r = -4 (Given)
2r + 2 = -4 (Simplify)
2r + 2 - 2 = -4 - 2 (Subtract 2 on both sides)
2r = -6 (Simplify)
2r/2 = -6/2 (Divide 2 on both sides)
r = -3 (Simplify)
5,356+2,398
=(5,356+2)+ (2,398 + 2)
5,358+2400=7,758
is kElly's answer correct? what mistake did she make?
Answer:
No because she added 2 instead of 2398. She thought the 2 was separate because of the comma separating the 2 thousand. She also made a mistake by thinking she could add easily by adding 2 to 2398 to make 2400.
The addition of the given numbers is 7,758.
Use the concept of addition defined as:
In mathematics, addition is an arithmetic operation that combines two or more numbers to produce a sum.
It is a fundamental operation used to calculate the total or the result of combining quantities. When adding numbers, you start with the first number, and then incrementally add subsequent numbers to obtain a final sum. The order in which numbers are added does not affect the result, thanks to the commutative property of addition.
This fundamental concept of addition forms the basis for more advanced mathematical operations and problem-solving techniques.
The given numbers are:
5,356+2,398
Now simply add these numbers:
5 3 5 6
+2 3 9 8
7 7 5 4
Hence,
The addition of the given numbers is 7,758.

In the figure, x= ?, y= ?, and z= ?
Answer:
x = 95
y = 147
z = 128
Step-by-step explanation:
x can be found by using the exterior angle triangle theorem, where, when you add the two opposite angles, it equals the measure of the exterior angle. In this case, 50 + 45 = 95.
The same theorem can be used to solve for y. 95 + 52 = 147
We see that angle z is composed of a linear pair, and we have one of the angle values, so just do 180 - 52 and you get 128.

Multiply both sides by 1/(x + 1) :

Simplify the following expression and show your work in details please .
Answer:
[tex]4m + 5 - 3m \\ = 4m - 3m + 5 \\ = 1m + 5 \\ = (m + 5)[/tex]
Given the expression:
[tex] \displaystyle \large{4m + 5 - 3m}[/tex]
To simplify the expression, notice that 4m and 3m have the same term.
These are called like terms. Let's see some examples of like terms.
x and 58x both are like terms because they have same x.90y and 35664y both are also like terms because they have same y.Then we also have the example of non-like term
50 and x both are not like terms because 50 is a constant and not a variable and x is not a number.920x and 790y both are not like terms because both have different variables.x and x^2 are not like terms as well because different degrees.In conclusion,
like terms have to be the same term and same degree.And that brings us to this topic, to evaluate or simplify the expression with two like terms and one non-like term.
Note that only like terms can evaluate. Let's see some examples:
5x+9x would be 14x since they are like terms and thus can be evaluated.x+x would be 2x. x is equivalent to 1x so 1x+1x = 2x. They are also like terms as well.How about a subtraction?
9x-2x would be 7x. x-x would be 0.10y-7y would be 3y.But what if it's non-like terms? Simple, we keep it like that!
8y+8z would be the same. They are not like terms so they cannot be evaluated.10x-7 would be the same as well. Not like terms.So to simplify the expression in the question, we evaluate like terms first!
Since 4m and 3m both are like terms. We can do 4m-3m.
[tex] \displaystyle \large{4m + 5 - 3m} \\ \displaystyle \large{4m - 3m + 5} [/tex]
Evaluate 4m-3m
[tex] \displaystyle \large{1m + 5} [/tex]
We don't usually write 1m so we keep as m instead.
[tex] \displaystyle \large{m + 5} [/tex]
Now, can we evaluate m+5? No, because m and 5 are not like terms so we keep like this.
Hence, the answer is m+5
