Step-by-step explanation:
A bird leaves its nest and travels 15 miles per hour downwind for x hours. On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
a. What is the distance of the entire trip?
miles
b. How long does the entire trip take?
_hours
_minutes and
_seconds
Answer:
A)
10 miles.
B)
0 hours, 40 minutes, and 0 seconds.
Step-by-step explanation:
Remember that distance is given by the formula:
[tex]d=st[/tex]
Where d is the distance, s is the speed, and t is the time.
We know that the bird leaves its nest and travels 15 miles per hour for x hours. So, let's substitute 15 for s and x for t:
[tex]d=15x[/tex]
On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
Since this is the return trip, the distance d remains the same. We know that the bird travels 3 miles per hour slower, so it's speed is 15-3 or 12 miles per hour.
However, after x hours, it still has 2 miles left until reaching the destination. So, we will subtract 2 from d. This gives us the equation:
[tex]d-2=12x[/tex]
We can solve this using substitution. Since we already know that d is 15x. Substitute:
[tex]15x-2=12x[/tex]
Solve for x. Subtract 12x from both sides:
[tex]3x-2=0[/tex]
Add 2 to both sides:
[tex]3x=2[/tex]
Divide both sides by 3:
[tex]x=2/3[/tex]
Therefore, the bird traveled for a total of 2/3 hours or 40 minutes.
And the distance the bird traveled is:
[tex]d=15x[/tex]
Substitute 2/3 for x to get:
[tex]d=15(2/3)=30/3=10\text{ miles}[/tex]
And we're done!

A half-marathon is 13.1 miles long. There is a water station every 1 1/3 miles along the race trail and at the finish line. How many water stations are needed for the half-marathon?
choices
15
13
10
11
Answer:
10 water stations are needed
Step-by-step explanation:
To get the number of water- station needed, we simply divide the total length of the half marathon by the distance where we can find a water station
mathematically,
that would be 13.1 divided by 1 1/3
= 13.1 divided by 4/3
= 13.1 * 3/4 = 9.825 which is approximately 10
Write -0.89 as a fractions.

Which statement correctly describes this expression 2m3-11 A. Twice the cube of the number subtracted from 11 B.the difference of twice a number and 11 cubes
A number is :
[tex]m[/tex]
_________________________________
Cube of it equals :
[tex] {m}^{3} [/tex]
_________________________________
Twice the cube equals :
[tex]2 {m}^{3} [/tex]
_________________________________
Subtract it from 11 equals :
[tex]2 {m}^{3} - 11 [/tex]
Which is the expression we have.
_________________________________
So the correct answer is A.
And we're done.
Thanks for watching buddy good luck.

A triangle has a base of 10 inches and a height of 8 inches. What percent of the area of the triangle is within 4 inches of the base?
Answer:
40%
Step-by-step explanation:
Firstly
Area of triangle when base is 10 inches and height is 8 inches
= 1/2*b*h
= 1/2*10*8
=40square inch
Again when base =4 inches
= 1/2*4*8
= 16square inches
percent of the area of the triangle is within 4 inches of the base
= 16/40*100%
= 40%
A triangle has an 8-inch height and a 10-inch base. The percent of the area of the triangle is within 4 inches of the base exists 40%.
What is meant by the area of triangle?Area of triangle = 1/2 (b h), where b is the base and h is the height, is the fundamental formula for calculating a triangle's area.
The type of the triangle and the known dimensions can affect other formulas that are used to calculate the area of a triangle.
Given: A triangle has an 8-inch height and a 10-inch base.
Let the equation be
Area of a triangle = (1/2) bh
substitute the values in the above equation, we get
= (1/2) × 8 × 10
= 40 square inches.
Once more with a 4 inch base
= 1/2 × 4 × 8
= 16 square inches.
Within 4 inches of the base, % of the triangle's surface area
= 16/40 × 100%
= 40%
Therefore, the percent of the area of the triangle is within 4 inches of the base exists 40%.

how to you find the simplest interest
Answer:

Step-by-step explanation:
Simple Interest
Simple interest represents a fee you pay on a loan or income you earn on deposits.
When borrowing money: You must repay the amount you borrowed and make extra payments for interest, which represents the cost of borrowing.
When lending money: You typically set a rate and earn interest income in exchange for making your money available to other people.
When depositing money: Interest-bearing accounts such as savings accounts pay interest income because you are making money available to the bank to lend to others.
How to Calculate It
In the following example, the term "simple" means you're working with the simplest way of calculating interest. Once you understand how to calculate simple interest, you can move on to other calculations, such as annual percentage yield (APY), annual percentage rate (APR), and compound interest.

1/5*p = 15 // : 1/5
p = 15/1/5
p = 75
p = 75

g(x) = 2 log(x - 1)
what is the inverse
Answer:
[tex]g^{-1}(x)=1+10^{x/2}[/tex]
Step-by-step explanation:
Inverse Function
Let's call:
[tex]y=2 log(x-1)[/tex]
Divide by 2:
[tex]y/2=log(x-1)[/tex]
Assuming the base of the log is 10, apply exponential base 10:
[tex]10^{y/2}=x-1[/tex]
Solving for x:
[tex]x=1+10^{y/2}[/tex]
Swap variables:
[tex]y=1+10^{x/2}[/tex]
Calling this function the inverse:
[tex]\boxed{g^{-1}(x)=1+10^{x/2}}[/tex]

Ayah akan membuat sebuah kolam ikan hias. Kolam tersebut berbentuk lingkaran dengan panjang diameter 80 cm, luas tanah yang di perlukan untuk membuat kolam adalah??
Answer:
[tex]A=5024\ cm^2[/tex]
Step-by-step explanation:
Father will make an ornamental fish pond. The pool is circular with a diameter of 80 cm, the area of land needed to make a pool is ??
The diameter of a circular pool, d = 80 cm
It means that,
Radius, r = d/2
r = 40 cm
We need to find the area of the land needed to make a pool. The area of a circular path is given by :
[tex]A=\pi r^2[/tex]
Put the values in the above formula.
[tex]A=3.14\times (40)^2\\\\A=5024\ cm^2[/tex]
So, it will require [tex]5024\ cm^2[/tex] area of land to make a pool.

farmer has 120 bushels of wheat to sell at her roadside stand. She sells an average of 16
5
8 bushels each day. Represent the total change in the number of bushels she has for sale after 5 days.
Answer:
The total change in the number of bushels she has for sale after 5 days is 83.125 bushels
Step-by-step explanation:
The given parameters are;
The initial number pf bushels the farmer has = 120 bushels
The amount of bushels of wheat the farmer sells each day = 16⁵/₈ = 16.625
The number of bushels sold after 5 days = 16.625 × 5 = 83.125 bushels
The total change in the number of bushels she has for sale after 5 days = The number of bushels sold after 5 days
The total change in the number of bushels she has for sale after 5 days = 83.125 bushels.
