1. Answer: The price of Andrea's tacos is $8.
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
Tip amount: $2.0
Percentage: 25% = 0.25 (decimal form, 25/100=0.25)
So, if we multiply the taco's price (x) by the percentage (0.25) we will obtain the amount of the tip (2).
Mathematically speaking:
x (0.25) = 2
Solving for x
x = 2/0.25
x = 8
The price of Andrea's tacos is $8.
2. To solve this problem what you can do is the following rule of three:
40 iris blooms -----> 100%
x iris blooms -------> 115%
Clearing the value of x we have:
x = (115/100) * (40)
x = 46
Then, comparing with last year we have:
40-46 = 6
Answer:
Savanna had this year 6 more iris blooms than last year.
Ennis wants to make a border for a triangular-shaped vegetable garden. He has 4 pieces of wood that measure 8 inches, 10 inches, 12 inches, and 18 inches. How many different triangular borders can ennis make?.
After considering all the combinations of three pieces of wood, we can conclude that Ennis can make 2 different triangular borders for his vegetable garden.
A triangle is a shape with three sides, and each side can be considered as a side length. In order to form a triangle, the sum of the lengths of the two shorter sides must be greater than the length of the longest side.
To find the number of different triangular borders that Ennis can make, we need to consider all the combinations of three pieces of wood as the sides of the triangle. There are four pieces of wood, so the number of combinations of three pieces is 4 choose 3, which is 4.
Now, we need to determine if each combination of three pieces of wood forms a triangle. If the sum of the lengths of the two shorter sides is greater than the length of the longest side, it forms a triangle. If not, it does not form a triangle.
If Ennis uses the 8-inch and 10-inch pieces as two sides, he can use the 12-inch or 18-inch piece as the third side, and it forms a triangle.
If he uses the 8-inch and 12-inch pieces as two sides, he can only use the 10-inch piece as the third side, and it forms a triangle. If he uses the 8-inch and 18-inch pieces as two sides, it does not form a triangle.

If the measure of each central angle of a regular polygon is 60degree. What is the measure of each interior angle
The measure of each interior angle is 120 degrees.
In conclusion, the measure of each interior angle of a regular polygon with central angles measuring 60 degrees is 120 degrees.
Measure of each interior angleThe measure of each interior angle of a regular polygon with central angles measuring 60 degrees can be found using the formula (n-2)180/n, where n is the number of sides of the polygon.
First, we need to find the number of sides of the polygon. Since the measure of each central angle is 60 degrees, we can use the formula 360/n = 60 to find the number of sides.
Solving for n, we get: 360/n = 60 360 = 60n n = 360/60 n = 6 So the polygon has 6 sides.
Now we can use the formula (n-2)180/n to find the measure of each interior angle:

The value of the greatest integer such that the smaller integer subtracted from 6 times the greater integer, difference is 41 is 8.
What is an Equation?An equation is a mathematical statement containing two expressions on either sides which are connected with an equal to sign.
Either sides of an equation is called as left hand side and right hand side.
Given that,
When an integer is subtracted from 6 times the next consecutive integer, the difference is 41.
Let the integer be x.
Then the next consecutive integer will be x + 1
6 times the next consecutive integer means 6 (x + 1).
an integer is subtracted from this means 6 (x + 1) - x.
The difference of this is 41.
6 (x + 1) - x = 41
By distributive property,
6x + 6 - x = 41
5x + 6 = 41
5x = 41 - 6

A backcountry airport has a runway that is 150 feet long. Approximately 75 feet past the runway is a large
grove of trees that average in height around 100 feet tall. What angle of elevation must a pilot take in
order to avoid crashing into the trees? Round to the nearest hundredths.
Select an answer
Question Help: Message instructor
To find the angle of elevation, we need to determine the height of the plane relative to the trees, and then use the tangent function to find the angle. Let's call the height of the plane "h".
We can set up a right triangle with the height of the plane, the distance from the runway to the trees, and the height of the trees.
We have:
h / (150 + 75) = 100 / h
Solving for h, we find that:
h = 125
So the height of the plane relative to the trees is 125 feet.
Now we can use the tangent function to find the angle:
tan(angle) = 100 / 125
angle = tan^-1(100 / 125)
angle = approximately 53.13 degrees
Rounding to the nearest hundredths, the angle of elevation that the pilot must take to avoid crashing into the trees is 53.13 degrees.
what day is 75 days from now?
The date that is 75 days from now, if today is February 22, 2023, is May 8, 2023.
To find the date that is 75 days from now, we can start with the current date and add 75 days to it. This can be done by adding the number of days to the day of the month, and if necessary, advancing to the next month or year.
For example, if today is February 22, 2023, we can count forward 75 days on a calendar to find the date that is 75 days from now. This would take us to May 8, 2023.
Here is the mathematical calculation:
Current date + 75 days = (February 22, 2023) + 75 days
= February 22, 2023 + 75 days
= (February 22, 2023 + 31 days) + (44 days)
= March 25, 2023 + 44 days
= (March 25, 2023 + 30 days) + (14 days)
= April 24, 2023 + 14 days
= (April 24, 2023 + 14 days)
= May 8, 2023
Therefore, the date that is 75 days from now, if today is February 22, 2023, is May 8, 2023.

The amount of time Jill trained for a marathon this month is 125% of the amount of time she trained last month. If Jill trained for 80 hours last month, how many hours did she train this month?
I need to do this in the Percent Porportion way. I know how to do it but I do not know the awnser. :)
Answer:
The amount of time Jill trained this month is 125% of the amount of time she trained last month, which was 80 hours. To find the number of hours she trained this month, we can multiply 80 hours by 125%:
80 hours * 125% = 80 hours * 1.25 = 100 hours
So Jill trained for 100 hours this month.
Answer:
100hours
100 hours / 80 hours * 100% = 125%
Step-by-step explanation:
The amount of time Jill trained this month is 125% of the amount of time she trained last month, which was 80 hours. So, she trained for 125% of 80 hours = 100 hours.
To find this answer as a percentage, we can calculate what percentage of 80 hours 100 hours is:
100 hours / 80 hours * 100% = 125%
So Jill trained for 125% of the amount of time she trained last month.

two trains, train a and train b weigh a total of 537 tons. train a is heavier than train b. the difference if their weights is 421 tons. what is the weight of each train?
Answer:
Let the weight of Train A be x tons. Then the weight of Train B is 537 - x tons. We know that the difference between their weights is 421 tons, so we can set up an equation to solve for x:
x - (537 - x) = 421
Expanding the right side:
x - 537 + x = 421
Combining like terms:
2x = 958
Dividing both sides by 2:
x = 479
So Train A weighs 479 tons and Train B weighs 537 - 479 = 58 tons.

The volume of the cone is 471 cubic yards and the radius is 5. What is the height of the cone?
ues 13.4 for π
Answer:
Step-by-step explanation:
The formula for the volume of a cone is given by:
V = (1/3)πr^2h
where V is the volume of the cone, r is the radius of the base, h is the height of the cone, and π is the mathematical constant pi (approximately equal to 3.14159).
Substituting the given values, we get:
471 = (1/3) x 13.4 x 5^2 x h
Multiplying both sides by 3 and dividing by 13.4 x 25, we get:
h = 471 x 3 / (13.4 x 25)
h ≈ 6.98 yards (rounded to two decimal places)
Therefore, the height of the cone is approximately 6.98 yards.
