Here are some letters and what they represent. All costs are in dollars. M represents the cost of a main dish n represents the number of side dishes s represents the cost of a side dish t represents the total cost of a meal What does ns = 6 mean in this situation?
Answer:
[tex]ns=6[/tex] means total cost of side dishes is equal to 6.
Step-by-step explanation:
M represents the cost of a main dish.
n represents the number of side dishes.
s represents the cost of a side dish.
t represents the total cost of a meal
Total cost of side dishes = Cost of a side dish × Number of side dishes = ns
Therefore,
[tex]ns=6[/tex] means total cost of side dishes is equal to 6.

On a map to cities are about 50 mm apart if the scale is 1 cm equals 15.5 miles how far apart are the two cities
Given:
On a map to cities are about 50 mm apart.
Scale is 1 cm equals 15.5 miles.
To find:
The distance between two cities.
Step-by-step explanation:
We have,
1 cm = 15.5 miles
It means
10 mm = 15.5 miles [1 cm = 10 mm]
Now,
10 mm on a map = 15.5 miles
1 mm on a map = [tex]\dfrac{15.5}{10}[/tex] miles
= 1.55 miles
50 mm on a map = 50 × 1.55 miles
= 77.5
Therefore, the two cities are 77.5 miles apart.
A triangle has exactly three sides. Prove the conditional by proving the contrapositive. If a polygon has more than three sides, then it is not a triangle. Contrapositive: If _____, then _____. Since ______, the contrapositive is _____, the original statement must be _____.
Answer:
If a polygon is a triangle, then it has exactly three sides
Since as have been presented above, the contraposition is true, the original statement must be true
Step-by-step explanation:
The contrapositive statement; If a polygon has more than three sides, then it is not a triangle
We have that the definition of a triangle = A polygon with exactly three sides
Therefore;
A polygon with more than three sides is not a triangle and has (n - 1)/2×180 degrees interior angle, where n = The number of sides
Therefore, when n > 3, (n - 2)/2×180 > 180°
The sum of interior angles of a triangle = 180°
Therefore, the contrapositive statement, if a polygon has more than three sides, then it is not a triangle is true
Therefore, we have;
If a polygon is a triangle, then it has exactly three sides
Since as have been presented above, the contraposition is true, the original statement must be true
what is the equation of a like that goes through the point 5,-2 and has a slope of. 6/5
Answer:
y= 6/5x -8
Step-by-step explanation:
The slope-intercept form (basically the form for the equation of a line)
y=mx+b
m is the slope
x is the value you want to plug in, or the x term in a point (x, y)
we know so far,
y=6/5x + b
so to find the missing value let's plug in the x & y value from (5, -2) and use the given slope
-2 = 6/5(5) + b
6 / 5 x 5/1 or 6/5 times 5 is 30/5 or 6
so
-2 = 6 + b
subtract 6 from each side to isolate the b value or y-intercept ( the point on the graph that is on the y-axis)
-8 = b
2. A computer shop charges P20.00 per hour (or a fraction of an hour) for the first
two hours and an additional P10.00 per hour for each succeeding hour. Find how
much you would pay if you will use one of their computers for: (a) 40 minutes (b) 3
hours (C) 150 minutes?
Answer:
(a) For 40 minutes the charge is P20.00
(b) For 3 hours the charge is P30.00
(c) For 150 minutes the charge is P30.00
Step-by-step explanation:
The given parameters are;
The amount the computer shop charges for the first two hours = P20.00
The amount the computer shop charges for a fraction of an hour = P20.00
The amount the computer shop charges for each extra hour = P10.00
Therefore, the amount the computer shop will charge for each time, is given as follows;
(a) For 40 minutes, we have;
The duration of 40 minutes is less than two hours, therefore, the amount the computer shop will charge = P20.00
(b) For a duration of 3 hours, the amount the computer shop will charge is given by the following relation
The amount charged for the first two hours = P20.00
The amount charged for the next extra hour to make 3 hours = P10.00
The total amount charged for the 3 hours = P20.00 + P10.00 = P30.00
(c) For a duration of 150 minutes, we have;
150 minutes = 2 hours 30 minutes
Therefore, the amount charged will be equivalent to the amount charged for 3 hours or P20.00 + P10.00 = P30.00.
The amount you would pay if you will use one of their computers for:
40 minutes40 minutes is within the range of the first 2 hours. Therefore, you will pay P20.00 using their computers for 40 minutes.
3 hours3 hours can be divided into: 2 hours + 1 hour
Charges per hour for the first 2 hours = P20.00
Charges for each succeeding hour = Additional P10.00
Hence: 2 hours + 1 hour
P20.00 + P10.00
= P30.00
Therefore, you will pay P30.00 using their computers for 3 hours.
150 minutesConverting 150 minutes to hours
60 minutes = 1 hour
150 minutes = ?
150/60
= 2 .5 hours = 2 hours 30 minutes
3 hours can be divided into: 2 hours + 1 hour
Charges per hour for the first 2 hours = P20.00
Charges for each succeeding hour = Additional P10.00
Therefore, you will pay
2 hours + 30 minutes
P20.00 + P10.00
= P30.00
Therefore, you will pay P30.00 using their computers for 150 minutes.

ITS DUE SOOM
Answer:
Tyler is correct. The temperature dropped at a rate of about 4° per hour between 4 and 6, while the temperature dropped at about 2.25° per hour between 6 and 10.
Edit: Explanation
The question is asking about which window of time had a faster decline in temperature, not a larger total change in temperature.
In a 2 hour timeframe, the temperature dropped 8°. (4-6 PM)
In a separate 4 hour timeframe, the temperature dropped 9°. (6-10 PM)
To find which window had a faster change in temp, I took the total temperature drop for each timeframe, then divided it by the number of hours each drop took.
8° / 2 = 4° per hour for 4-6 PM
9° / 4 = 2.25° per hour from 6-10 PM
Since the speed at which the temperature dropped per hour was greater from 4-6 PM than 6-10 PM, Tyler was correct.
Answer:
i agree with Mai because she/he (im not really sure) said that the temperature changed quicker in the time between 6 and 10 pm. the temperature change was 9 in those 4 hours.
Step-by-step explanation:
well there's a 4 hour difference between all 3 of the times
4 pm - 6pm
25 - 17 = 8
8 degree difference
6 pm - 10 pm
17 - 8 = 9
9 degree difference
the temperature changed quicker during 6 pm to 10 pm

Choose the graph that matches the inequality y <-2x+4.
The graph for the Inequality y <-2x+4 is attached below.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
For example, Olivia is selected in the 12U Softball. How old is Olivia? You don't know the age of Olivia, because it doesn't say "equals". But you do know her age should be less than or equal to 12, so it can be written as Olivia's Age ≤ 12. This is a practical scenario related to inequalities.
Given:
y <-2x+4.
The Inequality shows the shaded region in the Graph.
So, the intercept for the inequality is 4 and slope is of 2 units.
Hence, the graph for the Inequality y <-2x+4. is attached below.

For two numbers x and y, we have:
x + y = y + x

Then, we have
(a+b) + c = a + (b + c)
