On a dinner of cost $2.25, you want to add 15% to the bill. As a result, your lunch will cost more money overall $2.59.
How to find the calculation?In order to perform a computation, first change the 15% to an actual value. To do this with percentages, just divide the percentage (in this case, 15%) by 100. In terms of a precise mathematical value, the colloquial word "15%" thus becomes 15% / 100% = 0.15.You should next calculate the 15% portion of your $2.25 meal's cost.Always multiply 0.15 by $2.25 to arrive at this figure.
0.15 x $2.25=$0.34.
Your planned tip is $0.34, so that is how much you will give.As a result, your lunch will cost more money overall (to write on your charge slip or other payment)$2.25 + $0.34 = $2.59.

Amy counts butterflies for a science project.
She wants to know how many more butterflies she saw this month than in the past 4 months.
First she adds the number of butterflies she saw in the past 4 months.
She calls this number b. What should Amy do next?
Answer: After adding the number of butterflies she saw in the past 4 months and assigning it to the variable "b", the next step for Amy would be to add the number of butterflies she saw in the current month.
Once she has both the current month and the past 4 months total number of butterflies, she can then subtract the past 4 months total from the current month total.
The result will be the number of butterflies seen this month than in the past 4 months.
Amy can then record and analyze her data.

Comparing Fractions by finding common denominator
(Picture Attached)
Answer: see below
Step-by-step explanation:
In order to compare these fractions, we must first ensure that the fractions have common denominators (that is the number under the fraction bar). The easiest way to do this is to find the smallest number that both are factors of, which in this case can be done by multiplying 3 by 5. This equals 15. Now, whatever we multiply by the denominator to get 15, we must also multiply by the numerator.
1/3 * 5/5 = 5/15
2/5 * 3/3 = 6/15
Now that the denominators are the same, we can compare the numerators to find the larger fraction. Since 5 is less than 6, 1/3 < 2/5. Hope this helps!

To find the area of a composite figure, you need to determine the areas of all the individual shapes that make up the composite figure and add them together.
The result will be the total area of the composite figure, expressed in square units.
Here are some steps you can follow:
Identify all the shapes in the composite figure and label them.Find the area of each individual shape. The formula for the area of different shapes such as a rectangle, triangle, circle, etc.Add the areas of all the individual shapes to find the total area of the composite figure.Express the answer in square units.Example: If the composite figure is made up of a rectangle with area 36 square units and a triangle with area 18 square units, the total area A would be 36 + 18 = 54 square units.
In this case, figure number 1, consists of two rectangles. To find the area of a rectangle, use the formula width x height. Follow these steps:
Step 1: determine the formulas needed. In this case, since there are two rectangles, use the formula width x height.Step 2: break down the composite figure into simpler shapes to solve.Step 3: use the formulas to find the area of each rectangle. For the first rectangle, the width is 8 and the height is 2, so the area is 8 x 2 = 16. For the second rectangle, the height is 4 and the width is 5, so the area is 4 x 5 = 20.Step 4: finally, add the areas of all the rectangles together to find the total area. In this case, the total area is 16 + 20 = 36.Learn more about composite figure here: brainly.com/question/30292204

6. Find the coordinates of point P that lie along the directed line segment overline AB from A to B and partitions the line segment in the ratio of 2 to 3.
The ratio of AP to PB is 3 to 2 then the point P exists (8, 2).
What is meant by line segment?An area or portion of a line with two endpoints is known as a line segment. A line segment has a set length as opposed to a line. Both metric measurements, such as millimeters and centimeters, as well as conventional units, such as feet or inches, can be used to measure the length of a line segment.
An uncurved path with two ends is called a line segment. With points at either end, a line segment is drawn.
The arrowheads at both ends are used to portray it as a straight, lengthy, and continuous road. It stretches out both ways. The straight line that connects two places is called a line segment.
Since 3+2 = 5, we are dividing line segment AB into 5 congruent parts with point P 3/5 of the way from A to B.

The Average speed of Andrea on thursday is 63 mph and on wednesday was 70 mph.
What is Speed and Distance ?Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route. In other words, velocity is a vector, whereas speed is a scalar number.
The size or extent of the displacement between two points is referred to as distance. Keep in mind that the distance between two points and the distance traveled between them are not the same. The length of the entire journey taken to go from one point to another is the distance traveled.
The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.
Let the average speed on thursday be x mph
Average speed on wednesday was x+7 mph
The distance covered is the same on both journey so
3 * x = 2.7 * (x + 7)
