Actual distance between two places is 130 miles. The scale of the map is
1 in:100 miles. What is the distance between these two places in the map?
Answer:
1.3 inches
Step-by-step explanation:
1. Determine what you already know in order to set up the equation:
1 inch = 100 miles
x inches = 130 miles
Solving for x
2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)
[tex]\frac{100}{1}[/tex] = [tex]\frac{130}{x}[/tex]
3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)
100x = 130
4. Divide each side by 100 to isolate the variable.
x = 1.3
A particle is moving along the number line so that its distance (in meters) from the origin at any time t (in seconds) is given by s(t) = 8t2 + ln t.
The velocity of the particle at t = 1 second is:
Answer:
The velocity is 17 m/s
Step-by-step explanation:
To find the velocity, we find the first differential of the displacement
That will be
S’(t) = 16t + 1/t
We simply proceed to replace t with 1
That will give;
16(1) + 1/1
= 16 + 1 = 17 m/s

What is the equation in slope-intercept form of the line that crosses the x-axis at 12 and is perpendicular to the line represented by y = 6/5x + 9 ?
Answer:
The equation of the line in slope-intercept form is;
y = 10 - 5/6·x
Step-by-step explanation:
The given equation of the line to which the required line is perpendicular is presented as follows;
y = 6/5·x + 9
A point on the desired line = (12, 0)
The relationship of the slope, m₁ of a line, perpendicular to the another line of slope m₂, is given as follows;
m₁ = -1/m₂
Therefore;
The slope of the desired line = -1/(The slope of the given line)
The slope of the desired line = -1/(6/5) = -5/6
The equation of the desired line in point and slope form is given as follows;
y - 0 = -5/6 × (x - 12)
Therefore, the equation of the line in slope-intercept form is;
y = -5/6·x + 10 = 10 - 5/6·x.

Answer:
x> -10
Step-by-step explanation:
in order to find what the value of X is you have to multiply the 5 of the denominator into the -6 which would make -30.
You would then divide by 3 in order to get x by itself and would get -30÷3= -10
therefore the answer should be greater than -10
Hope this helped :)
Answer:
x > -10
Step-by-step explanation:
[tex]\frac{3x}{5} > -6[/tex]
Multiply both sides by 5/3
[tex]\frac{5}{3} * \frac{3x}{5} > \frac{5}{3} *(-6)[/tex]
Reduce Everything
[tex]x > -5*2[/tex]
Multiply
x > -10

If gym strong charges a $350 fee and $15 a month and gym fit charges $100 fee and $24 a month, how many months would take for gym string to be a better buy?
Answer:
It would take 28 months for Gym Strong to be a better buy.
Step-by-step explanation:
There are two possible options for gyms to choose from:
Gym Strong charges $350 plus $15 a month
Gym Fit charges $100 plus $24 a month.
Since Gym Strong charges less per month but has a higher initial fee, there will be some time when it will be a cheaper option than Gym Fit.
Let's solve this by analyzing the differences in fixed fees and monthly fees.
The difference of fixed fees is $350 - $100 = $250
The difference on monthly fees is $24 - $15 = $9
Both gyms will charge the same total fees when have passed 250/9 = 27.7 months. Since the number of months is a whole number, we round up.
It would take 28 months for Gym Strong to be a better buy.

Please help! I think of a number, I double it, and then add 3. The result is 19. Write this in the form of an equation and then solve the equation to find the number I was thinking of.
Answer:
8
Step-by-step explanation:
Y×2+3=19
19-3=16
16÷2=8
You subtract the 3 first to get what the number was when doubled. After getting that number you would divide it by 2 to get the number that you thought of.
Only 35 people out of the 250 to whom the offer was made refused it. What percent refused it?
Answer: 14% refused the offer.
Step-by-step explanation: Divide the number of refusals by the total sent.
35/250 = 0.14 Then multiply by 100 to change from decimal to percent.
The quick way to multiply by 100 is to move the decimal point two places to the right. (Delete the 0 at the left.)
0.14 × 100 = 14. So the answer is 14%

Which sequence of transformations will map figure Q onto figure Q′?

A) Translation of (x, y + 2), reflection over x = 1, and 180° rotation about the origin
B) Translation of (x, y − 2), reflection over x = 1, and 180° rotation about the origin
C) Translation of (x, y − 2), reflection over y = 1, and 180° rotation about the origin
D) Translation of (x, y + 2), reflection over y = 1, and 180° rotation about the origin
Answer:
Which sequence of transformations will map figure Q onto figure Q′?
Its D.Translation of (x, y + 2), reflection over y = 1, and 180° rotation about the origin
Step-by-step explanation:
The sequence of transformations that will map figure Q onto figure Q′ : 'Translation of (x, y + 2), reflection over y = 1, and 180° rotation about the origin.'
The correct answer is option (D)
What is translation?"It is a geometric transformation in which the displacement of a figure from one place to another."
What is reflection?"It is a geometric transformation where all the points of an object are reflected on the line of reflection."
What is rotation?"It is a transformation in which the object is rotated about a fixed point."
For given question,
Quadrilateral Q with coordinates (-9, 2) ,(-6, 4) ,(- 4, 4) , and (-2, 2) Quadrilateral Q' with coordinates (2, 2), (4, 4), (6, 4), and (9, 2)
Consider a point (-4, 4) of quadrilateral Q. If we reflect Q over x = 1, then it would push the x coordinate of (-4, 4) to new x value 5 units to the right of x = 1, which is x = 6, and 180 rotation would make x = -6 But x = -6 is not in Q' . So it must be reflection over y = 1.Consider the transformations at option C, First translate to (x, y - 2) So, the translation of (-4,4) becomes (-4, 2), reflection over y = 1 gives (-4, 4), and 180° rotation about origin gives (4, -4) which is not the coordinate of Q'Now, consider the translation of (x, y + 2) So, the translation of (-4, 4) becomes (-4, 6), reflection over y = 1 gives (-4, -4), and 180° rotation about origin gives (4, 4) which is the coordinate of Q'Therefore, the sequence of transformations that will map figure Q onto figure Q′ : 'Translation of (x, y + 2), reflection over y = 1, and 180° rotation about the origin'
The correct answer is option (D)
