Answer:
what??
Step-by-step explanation:
An aircraft flies against the wind for a distance of 300 miles in 2 hours then the aircraft makes the return trip with the wind in 1 hour what was the aircraft average speed for the entire trip
The aircraft's average speed for the entire trip, both against and with the wind, is 200 miles per hour. This is calculated by dividing the total distance travelled (600 miles) by the total time taken (3 hours).
Explanation:To solve this problem, we'll use the formula for average speed: Total Distance/Total Time. In this case, the aircraft flies 300 miles against the wind and 300 miles with the wind, so the total distance is 600 miles (300+300).
The total time is the time it takes to fly against the wind plus the time it takes to fly with the wind, which is 3 hours (2+1).
So, the average speed for the entire trip is 600 miles/3 hours = 200 miles per hour.

Kyle invests $20,000 in a partnership that has five other partners.
The total investment of the partners is $160,000. What percent of the
business is owned by the five other partners?
The percentage of the business that is owned by the five other partners is 87.5%.
Amount invested by Kyle = $20000
Total investment of the partners = $160000
The percentage of the business that is owned by the five other partners will be:
= ($160000 - $20000) / $160000 × 100
= $140000/$160000 × 100
= 87.5%
Therefore, the other partners have 87.5% of the investment.

d) Calculate the area of a circle with a circumference of 31.4 in.
Answer:
A ≈ 78.54
Step-by-step explanation:
Area of a circle is A=πr^2
Since you do not know r (radius) you take the formula for the circumference of a circle (C=2πr), plug in 31.4 for C, and solve for r
Now that you have the radius of 4.99746521, you round it up to 5 and solve the area formula with 5 in as r.

What is the distance between 178 and 313 on a number line some one help me
The distance between 178 and 313 on a number line is: 135
Step-by-step explanation:We know that the distance between two points a and b on a number line is equal to the absolute difference between the two numbers.
i.e. Distance between two numbers = |a-b|
Here we have:
a= 178
and b=313
This means that:
|a-b|=|178-313|=|-135|=135
C. You filled your car tank with gas at the beginning of the trip. At the start of
the trip, your odometer read 25,678 miles. At the end of your trip, your
odometer read 26,109 miles. When you filled your tank at the end of the trip,
it took 15 gallons of gas. How many miles per gallon did the car get?
Answer:
164
Step-by-step explanation:
To find the car's miles per gallon, divide the total miles traveled by the total gallons of gas used. In this case, the car got approximately 28.73 miles per gallon.
Explanation:To find the miles per gallon the car got, you need to divide the total miles traveled by the total gallons of gas used. In this case, the car traveled 26,109 - 25,678 = 431 miles and used 15 gallons of gas. Using the formula MPG = Miles / Gallons, we get MPG = 431 / 15 = 28.73 miles per gallon. Therefore, the car got approximately 28.73 miles per gallon.

A model for my number has
6 ones blocks, 2 hundreds blocks, and 3 tens
blocks. What number am I
Answer:
A model for my number has 6 ones blocks, 2 hundreds blocks, and 3 tens blocks. The model number is 236.
Solution:
Given that the model has 6 ones blocks, 2 hundreds blocks, and 3 tens blocks. The model number can be found out by,
[tex]\bold{\begin{array}{l}{=\text { (number of hundreds block } \times 100)+(\text { number of tens block } \times 10)+} \\ {\text { (number of ones block } \times 1)}\end{array}}[/tex]
Given that number of one blocks = 6 blocks. Hence we get [tex]6 \times 1=6[/tex]
Number of ten blocks = 3.Hence we get [tex]3 \times 10 = 30[/tex]
Number of hundred blocks = 2 .Hence we get [tex]2 \times 100=200[/tex]
So the model number = 6 + 30 + 200
=236
Hence the model number is 236.

Which quadratic function only has one x-intercept?
A f ( x ) = x 2 − 12 x + 36
B f ( x ) = x 2 − 13 x + 36
C f ( x ) = x 2 + 13 x + 36
D f ( x ) = x 2 + 20 x + 36
Answer:
f(x) = x² - 12x + 36 = (x - 6)²
The correct answer is A.
The quadratic function that has only one \(x\)-intercept is A. [tex]\( f(x) = x^2 - 12x + 36 \)[/tex]
A quadratic function has only one [tex]\(x\)[/tex]-intercept if it touches the [tex]\(x\)[/tex]-axis at exactly one point, which happens when the discriminant [tex](\(\Delta\))[/tex] of the quadratic equation is zero. The discriminant of a quadratic function [tex]\(ax^2 + bx + c = 0\)[/tex] is given by:
[tex]\[ \Delta = b^2 - 4ac \][/tex]
Let's calculate the discriminant for each given function to determine which one has only one [tex]\(x\)[/tex]-intercept.
Option A: [tex]\( f(x) = x^2 - 12x + 36 \)[/tex]
[tex]\[ a = 1, \, b = -12, \, c = 36 \][/tex]
[tex]\[ \Delta = (-12)^2 - 4 \cdot 1 \cdot 36 \][/tex]
[tex]\[ \Delta = 144 - 144 \][/tex]
[tex]\[ \Delta = 0 \][/tex]
Option B: [tex]\( f(x) = x^2 - 13x + 36 \)[/tex]
[tex]\[ a = 1, \, b = -13, \, c = 36 \][/tex]
[tex]\[ \Delta = (-13)^2 - 4 \cdot 1 \cdot 36 \][/tex]
[tex]\[ \Delta = 169 - 144 \][/tex]
[tex]\[ \Delta = 25 \][/tex]
Option C: [tex]\( f(x) = x^2 + 13x + 36 \)[/tex]
[tex]\[ a = 1, \, b = 13, \, c = 36 \][/tex]
[tex]\[ \Delta = 13^2 - 4 \cdot 1 \cdot 36 \][/tex]
[tex]\[ \Delta = 169 - 144 \][/tex]
[tex]\[ \Delta = 25 \][/tex]
Option D: [tex]\( f(x) = x^2 + 20x + 36 \)[/tex]
[tex]\[ a = 1, \, b = 20, \, c = 36 \][/tex]
[tex]\[ \Delta = 20^2 - 4 \cdot 1 \cdot 36 \][/tex]
[tex]\[ \Delta = 400 - 144 \][/tex]
[tex]\[ \Delta = 256 \][/tex]
Only option A has a discriminant of 0, which means it has exactly one \(x\)-intercept.

-3(y+3)=2y+3
what’s the answerrr is there even a solution???
Answer:
y = -2 2/5
Step-by-step explanation:
-3(y+3)=2y+3
-3y - 9 = 2y + 3
-3y - 2y = 3 + 9
-5y = 12
y = 12/-5 = -12/5 = - 2 2/5
-3(y+3)=2y+3
Mutiply the bracket by -3
(-3)(y)= -3y
(-3)(3)= -9
-3y-9= 2y+3
Move -9 to the other side
Sign changes from -9 to +9
-3y-9+9= 2y+3+9
-3y= 2y+3+9
-3y= 2y+12
Move 2y to the other side
Sign changes from +2y to -2y
-3y-2y= 2y-2y+12
-3y-2y=12
-5y= 12
Divide both sides by -5
-5y/-5= 12/-5
Answer:
y= -12/5 or y=- 2 2/5

use the digits 0-7 to create two 4 digit numbers whose sum is greater than 9999.
Answer:
7,045 and 6,123. The sum is 13,168
Answer:
The numbers 7654 and 5463 meets the given conditions.
Step-by-step explanation:
We are given the following information in the question:
We have to create two four digits number from the digits between 0 and 7 such that there sum is greater than 9999.
Let x and y be the four digits number, then x and y must satisfy the equation:
[tex]x + y > 9999[/tex]
We choose the number 7654 and 5463. These are randomly fenerated from digits between 0 and 7.
Adding the two numbers:
[tex]x + y = 7654 + 5463 = 13117 > 9999[/tex]
Hence, the numbers 7654 and 5463 meets the given conditions.

Jackson wants to divide a pound box of
trail mix into small bags. Each of the bags
will hold pound of trail mix. How many
bags of trail mix can Jackson fill?
Jackson can fill 2 bags of trail mix, with each bag holding ½ pound of trail mix.
To calculate how many bags of trail mix Jackson can fill:
First, determine how many bags can be filled with 1 pound of trail mix:
1 pound bag ÷ ½ pound per bag = 2 bags
Next, divide the pound box into bags: 1 pound box ÷ ½ pound per bag = 2 bags
Therefore, Jackson can fill 2 bags of trail mix.
A large multiplex movie house has many theaters. The largest theater has 44 rows. There are 20 seats in the first row. Each row has four seats more than the previous row. How many total seats are there in this theater?
The total number of seats in this movie theater is 4224. This is calculated using the sum of an arithmetic series formula.
Explanation:The question describes an arithmetic sequence where each row in the theater has four more seats than the previous row. The first row has 20 seats and the last row (44th row) has[tex]20 + 4*(44-1) = 172[/tex] seats. The total number of seats in this theater is therefore the sum of an arithmetic series formula, which is given by:
[tex]S = n/2 * (a + l)[/tex]
Where:
S is the sum of the sequence n is the number of terms a is the first term l is the last term
So for the number of seats, we have:
[tex]S = 44/2 * (20 + 172) = 22 * 192 = 4224.[/tex]
So, the total number of seats in the theater is 4224.
