the total points scored in a basketball game can be calculated using the expression 3c - 3 if c = 41, how many points total were scored
Answer:
its actually 126
Step-by-step explanation:
The total points scored in the basketball game is 120 points.
Explanation:To find the total points scored in a basketball game, we can use the expression 3c - 3. Given that c is equal to 41, we can substitute this value into the expression to calculate the total points.
So, 3c - 3 = 3(41) - 3 = 123 - 3 = 120.
Therefore, a total of 120 points were scored in the basketball game.

two cruise ships are sailing towards each other from caribbean islands that are 264 km apart, one ship travels 4 km/h faster than the other. if they both started at the same time. and meet after 6h. how fast is the other ship travelling?
The slower ship is traveling at a speed of 21 km/h, while the faster ship is traveling at a speed of 25 km/h.
Explanation:This is a mathematics problem that involves solving for unknown speeds with the given conditions. Lets assume the speed of the slower ship is x km/h. Thus, the speed of the faster ship is x+4 km/h. They are moving towards each other, thus their combined speed is (x+x+4) km/h. As speed is distance over time, we can set up the equation: (2x+4)*6 = 264. Solving this equation, we end up with x=21 km/h as the speed of the slower ship, and hence the speed of the faster ship is 25 km/h.

Which statement is true about the difference 2√7-√28
Which does not describe the same situation?
Answer:
4. Option 3rd.
Step-by-step explanation:
In this question, three options are given.
We need to describe the same situation.
First option: y = 3 + 6x
this equation represent the equation of a line. In that line all the points are related with each other with same relation.
So, this equation describe the same situation.
Second equation:
y is two more than six times x.
We write this situation in equation form.
y = 6x + 2
this is also describe the same situation.
Third option:
this table shows the x-y relation table.
Here no two points are describe the same situation.
So, option 3rd doesn't describe same situation.

A shop makes $37.50 for selling 15 calendars. If the shop wants to make $2450, how many calendars does it need to sell?
The shop needs to sell 980 calendars to make $2450.
To find out how many calendars the shop needs to sell to make $2450, we first determine the price per calendar by dividing the total amount made from selling a batch of calendars by the number of calendars in that batch. The shop makes $37.50 from selling 15 calendars, so each calendar is sold for $37.50 / 15 = $2.50. To reach the goal of $2450, we need to calculate the number of calendars by dividing the target amount by the price per calendar.
$2450 / $2.50 = 980 calendars

A circle and a square have the same area. find the length of the diagonal of the square divided by the radius of the circle.
Let us say that the square have edge = sqrt(pi), then its area is pi since A = edge^2, and therefore the diagonal is pi*sqrt(2).
Meanwhile the circle of radius 1 has area pi since area of circle is A = pi *radius^2.
Therefore we get that the diagonal of the square divided by the radius is:
diagonal / radius = pi*sqrt(2) / 1 = pi*sqrt(2)

Reflection : Across the line y = 1
Reflecting across y = 1 means each point's position stays the same horizontally but mirrors vertically across the line.
When reflecting a point or shape across a line, y = 1,
it means that each point is mirrored on the other side of the line while maintaining the same distance from the line.
Here, the line y = 1 acts as a "mirror" or "axis of reflection."
To reflect a point (x, y) across the line y = 1, follow these steps:
Find the vertical distance between the point and the line y = 1. Let's call this distance "d."
If the point is above the line (y > 1), then d = y - 1.
If the point is below the line (y < 1), then d = 1 - y.
Move the point to the same vertical distance on the other side of the line y = 1.
If the point was above the line (y > 1), the new reflected point will be (x, 1 + d).
If the point was below the line (y < 1), the new reflected point will be (x, 1 - d).
Keep in mind that the x-coordinate remains the same in both cases since the line of reflection is vertical (parallel to the y-axis).
By repeating these steps for all points in a shape, obtain the reflection of the entire shape across the line y = 1.

An office uses 478 pounds of paper in one week. The paper comes in packages that hold 18 pounds of paper each. How many packages of paper does the office use each week?
The office uses 26 and a half package of papers.
What is division?Division is the process of splitting a number or an amount into equal parts.
Given that, An office uses 478 pounds of paper in one week. The paper comes in packages that hold 18 pounds of paper each.
To find the number of packages of paper, the office use each week, we will divide the total paper used in one week to paper in 1 package
Therefore, the number of packages of paper, the office use each week = 478 / 18 = 26.5
That means they are using 26 package plus a half package in one week.
Hence, The office uses 26 and a half package of papers.

what is the slope of the function?
-3
-2
3
4
Answer:
The answer is 3.
Step-by-step explanation:
In order to determine the slope of the function, we have to know about linear function.
In any linear function, we can get its slope using two pairs of coordinates that belong to the linear function.
m=Slope of the linear function.
P1=(x1,y1)=First pair of coordinate.
P2=(x2,y2)=Second pair of coordinate.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
In this case, we have many pairs of coordinates, so we choose two of them:
[tex]P_1=(-1,1)\\P_2=(0,4)[/tex]
Then, we replace them in the slope formula:
[tex]m=\frac{4-1}{0-(-1)}=\frac{3}{1}=3[/tex]
Finally, the slope of the function is 3.
