What is the solution to the equation below?
5 - n/2 = 12
Step-by-step explanation:
5 - n/2 = 12
10/2 - n/2 = 12
n = (12 × (-2)) + 10
n = (-24) + 10
n = -14
Let's prove it :
[tex]5 - ( - \frac{14}{2} ) \\ = \frac{10}{2} + \frac{14}{2} \\ = \frac{24}{2} \\ = 12[/tex]
Conclusion :
5 - n/2 = 12
5 - (-14/2) = 12
and
n = -14
A quiz has eight multiple choice questions with four options for each ( A B C & D ) how many ways are there to answer the question
Answer:
1680 ways.
Step-by-step explanation:
This question is solved using Permutation formula.
Permutation formula is given as
nPr = n! / (n -r)!
In the above question we are to find how many ways we can answer 8 multiple choice questions with 4 options(A, B,C,D)
Therefore,
n = 8 multiple choice questions
r = 4 options
nPr = n! / (n - r)!
8P4 = 8! / ( 8 - 4) !
8P4 = 8! / 4!
8P4 = (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (4 × 3 × 2 × 1)
8P4 = 40320 / 24
8P4 = 1680 ways
Therefore, the number of ways to answer 8 multiple choice questions with 4 options (A, B, C, D) for each is 1680 ways.
Answer:
65,536 ways.
Step-by-step explanation:
The Fundamental Counting Principle states that:
"If decision M can be made m ways and decision N can be made n ways, then the two decisions can be made m⋅n ways"
Therefore, we can create a model of the eight questions by drawing eight blanks:
_ _ _ _ _ _ _ _
Then, filling in each "question" with the number of options for each, which is four:
4 4 4 4 4 4 4 4
And finally, we can multiply the fours together, which would be 4⋅4⋅4⋅4⋅4⋅4⋅4⋅4 or 4⁸, which is equal to 65,536.

To save for a car when he turns 18, Pascale deposited $500 each year into a savings account with a 7.5% interest rate compounded annually.
Using the formula A = P (1 + r) Superscript t, what is the value of the account at the end of the fifth year?
A.$3,071.92
B.$3,122.00
C.$3,851.77
D.$4,140.65
Answer:
$3122.00
Step-by-step explanation:
Since we have been given that
Initial amount deposited into a savings account each year = $500
Rate of interest compounded annually = 7.5%
Number of years = 5 years
So, Amount in the account at the end of the fifth year would be:
A = P( 1+r )^5} - 1
500{(1+7.5/100) - 1 }÷ ( 7.5/100)} (1+7.5/100)
500{( 1.075^5 -1/0.075} × 1.075
500( 1.4356 -1/0.075) × 1.075
500( 0.4356/0.075) × 1.075
500(5.80839)×1.075
= 3122.01
$3122.00

A. (-8,-4)
B.(-4,-8)
C.(-4,4)
D.(4,-4)
Answer:
B. (-4, -8)
Step-by-step explanation:
Put -4 into the first equation where x is, then evaluate. You will find ...
y = (1/2)(-4) -6 = -2 -6 = -8
Then the point that satisfies both equations is ...
(x, y) = (-4, -8) . . . . matches choice B

You can eliminate choices A and D, because they don't have -4 for the x-value.
You discovered 1000 grams of an unknown element called Coolium 23 that has a half life 23 days. How long will it take for you to have 600 grams remaining.
Answer:
13.8 days
Step-by-step explanation:
In this case we can solve it by means of a rule of three, knowing the amount of life for 1000 grams, it must be proportional for 600 grams, like this:
grams days
1000 23
600 x
x = 600 * 23/1000
x = 13.8
which means that for the 600 grams it would be an average life of 13.8 days.

Câte diagonale are un poligon cu 5 laturi, dar cu 6 laturi?
Your question isn't clear. But I infer this is the clear rendering of it;
How many diagonals does a polygon have with 5 sides, but with 6 sides?
Answer:
a. For 5 sides= 5
b. For 6 sides= 9
Step-by-step explanation:
Remember, this is the formula to calculate the number of diagonals of a polygon;
n (n-3) / 2 where n is the sides.
Thus,
for 5 sides= 5 (5-3) /2
= 5 (2) /2 = 10/2= 5
for 6 sides= 6 (6-3) /2
= 6 (3) /2 = 18/2= 9
In Circle M, points A, B, and C are located on the circle such that measure angle CBM equals to 34 degrees. What represents angle CAB
Answer:
Angle CAB=56 degrees

Two lines defined by the equations $y = mx + 4$ and $y = 3x + b$, where $m$ and $b$ are constants, intersect at the point $(6, 10)$. What is the value of $b + m$?
Answer:
-7
Step-by-step explanation:
The two lines intersect at the point (6,10), so this point belongs to both lines. This means that if we use the value of x = 6 in the lines, we will find y = 10
So we can use this point to find the values of b and m:
y = mx + 4
10 = 6m + 4
6m = 6
m = 1
y = 3x + b
10 = 3*6 + b
b = 10 - 18 = -8
So the value of b + m is -8 + 1 = -7
After substituting the intersection point (6, 10) into both line equations and solving for m and b respectively, we find that the value of b + m is -7.
To find the value of b + m when two lines intersect at the point (6, 10), we can substitute the coordinates of the intersection point into both line equations. Since the coordinates (6, 10) must satisfy both equations, we have:
For the first equation y = mx + 4:
10 = m*6 + 4,
which simplifies to:
m = 1.
For the second equation y = 3x + b:
10 = 3*6 + b,
which simplifies to:
b = -8.
Having both values, we can now calculate b + m:
b + m = (-8) + 1 = -7.
The value of b + m is -7, which represents the sum of the y-intercept of the second line and the slope of the first line.
The table shows the prices of 8 different treadmills at a sporting goods
store. This week the store is having a 50% off sale on all treadmills. What
are the mean, median, mode and range of the discounted prices?
$640 $810||$755 $810
$1175 $900 $1080 $530
mean: $736.25, median: $900; mode: $810; range: $645
mean: $837.50; median: $810; mode: $810; range: $645
mean: $368.13, median: $450; mode: $405; range: $322.50
mean: $418.75; median: $405; mode: $405; range: $322.50
The mean of the discounted prices is $736.25, the median is $810, the mode is $810, and the range is $645.
Explanation:To find the mean of the discounted prices, we add up all the prices and divide by the total number of prices. In this case, the mean is $736.25 because (640 + 810 + 755 + 810 + 1175 + 900 + 1080 + 530) / 8 = 736.25.
To find the median of the discounted prices, we arrange the prices in ascending order and find the middle value. Since there are 8 prices, the median is the average of the 4th and 5th values, which are $810 and $810, respectively. So, the median is $810.
To find the mode of the discounted prices, we look for the value that appears most frequently. In this case, $810 appears twice, which is more often than any other price. Therefore, the mode is $810.
To find the range of the discounted prices, we subtract the smallest price from the largest price. In this case, the range is $645 because $1175 - $530 = $645.

∠1 and ∠2 form a straight angle. ∠1 has a measure of 28°.
What is the measure of ∠2? PLZ HELP
Answer:
∠2 = 152
Step-by-step explanation:
A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.
That means that 180-28, will give us our other angle.
Answer:
152°
Step-by-step explanation:
Angles on a straight line add up to 180°
Angle 2 + 28 = 180
Angle 2 = 180 - 28

1. Write the ratio in the simplest form. (1 point)
45:15
9:3
3:1
1:3
4:1
Answer:
45:15=9:3=3:1
9:3=3:1
3:1 stays the same.
1:3 stays the same.
4:1 stays the same.
The simplify ratios such as 45:15 and 9:3. The simplified form of 45:15 and 9:3 is 3:1. The correct option is B.
To write the ratio 45:15 in the simplest form, you have to divide both numbers by their greatest common divisor (GCD), which in this case is 15.
So, 45 divided by 15 is 3, and 15 divided by 15 is 1, which gives us the simplified ratio of 3:1.
[tex]\frac{45}{15} = \frac{3}{1}[/tex]
For the ratio 9:3, again, we divide both numbers by their GCD, which is 3, resulting in the simplified ratio 3:1.
The ratio 3:1 is already in its simplest form.
1:3 is the simplest form and 4:1 is the simplest fraction.
Which line appears to have the same slope as the equation x-y=4 and has a y-intercept that is 2 units above the y-intercept of the given equation?
Answer:
B
Step-by-step explanation:
First, find the y-intercept form of the equation:
x - y = 4
x - x - y = 4 - x
-y = 4 - x
-y = -x + 4
-y/-1 = -x/-1 + 4/-1 (to get the y positive)
y = x - 4
The y-intercept is -4. This means that a y-intercept two units above 4 would be -2. Whichever line crosses the y axis at the value of -2 is the answer (line B)

Out of the 30 days in June, you run 13 days and swim 6 days. You lift weights 7 days and ride a bike 4 days. If you make a pie chart to show this data, how many degrees of the circle should represent swimming?
Answer:
3. 72 degrees
Step-by-step explanation:
We can convert the values to percentage values and since a circle is 360°, we can multiply the percentages with 360° to get the degrees. The total of day is all the the things added up:
= 13+6+7+4=30
Percent swimming:
=(6/30) times 360= 72
Answer is 72 degrees
Answer:
Step-by-step explanation:
swim = 6/30= 0.2 -> 0.2*360 = 72 degree
run = 13/30= 0.433 -> 0.4333 *360 = 156 degree
lift weight = 7/30 = 0.23333 -> 0.23333 *360 = 84 degree
ride bike = 4/30 = 0.133333 -> 0.133333 *360 = 48 degree
