Miley and Cole ended up making the same number of biscuits for a bake sale at school, even though Miley made them in batches of 7 biscuits and Cole made them in batches of 11 biscuits. What is the smallest number of biscuits each must have baked?

Answers

Answer:

The smallest number is 77

Step-by-step explanation:

The LCM of 7 and 11 is 77 and I did LCM because it says "smallest number" which means I have to do LCM.

Answer:

Step-by-step explanation:

They each start at 0. Miley will be making them in groups of 7 and Cole 11.

Miley: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77.

Cole: 11, 22, 33, 44, 55, 66, 77.

Mark's bill for lunch at a restaurant is $14.50, and he wants to leave a 18% tip.
How much should he leave for the tip?

A. $2.18

B. $2.61

C. $11.60

D. $261.00

Answers

It’s B because you divide 18 percent from 14.50 dollars.

It would be B. Because 14.50 times .18 equals 2.61. Just put a decimal on it and move it to the right twice and multiply that by 14.50. If you need a better explanation you can message me! Hope this helps!:)

This is the graph of a __function.

The smallest positive x-intercept of the graph is located at x=
The greatest value of y is y=___, and it occurs when x=
For x between x = π and 2π, the function value y ___ 0

Answers

Answer:

1) Cos

2) 1

3) π

4) 1

5) y < 0

Step-by-step explanation:

Cos

The y-intercept is the value of y when x=0, ie the value of y when the line meets the y-axis. We can see from the graph that this is 1.

The x-intercept is the value of x when y=0, ie the value of x when the line meets the x-axis. We can see from the graph that the smallest positive value of x when the line crosses the x-axis is π.

Highest y value from graph is 1, and besides, for cos graphs, y≤1.

We can see from the graph that between x=π and x=2π, the function is bellow the y-axis, ie y<0.

The graph is of a cos function. The y-intercept of the graph is the function value y=1. The smallest positive x-intercept of the graph is located at x=π. The greatest value of y is y=1, and it occurs when x=2π. For x between x = π and 2π, the function value y<0.

The point on the graph where it crosses the y-axis is known as the y-intercept. The y-intercept in this situation is zero since the graph crosses the y-axis at (0, 0).

The point at which the graph first crosses the x-axis at a positive value of x is known as the graph's smallest positive x-intercept. The graph in this instance crosses the x-axis at (x,0), making the smallest positive x-intercept.

The maximum value of the function is equal to the highest value of y. The greatest value of y in this situation is 1, and it happens when x = 2.

The function value y declines from 1 to 0 for x between x = and 2. You can observe this by examining the graph.

Do 2 or more shapes with the same perimeter have to have the same area? Explain with examples. AND Do 2 or more shapes with the same area also have to have the same perimeter? Explain.

Answers

Yes. Take for example a square and an ellipsis with the same perimeter. The family of ellipses with the same perimeter can have any area between that of a circle to zero (if it is extremely “thin” i.e. if its eccentricity is large). The circle has the maximum area of any other shape with the same perimeter, so the square has the same area of one of the intermediate ellipses.
