The relative velocity of one plane with respect to the other plane is given
by the sum of the velocity of the two planes.
The time it would take the two planes to meet is [tex]\underline{1. \overline 6 \ km/hr}[/tex]Reasons:
The distance between the two airports = 2,400 km
Speed of the plane from NAIA = 800 kilometer per hour
Speed of the plane coming from SIN = 640 kilometers per hour
Let t represent the time after which the two planes meet, we have;
800 × t + 640 × t = 2,400
[tex]\displaystyle t = \frac{2,400 \ km}{800 \ km/hr + 640 \ km/hr} = \frac{5}{3} \ km/hr = 1.\overline 6 \ km/hr[/tex]
The time after which the two planes meet, t = [tex]\underline{1. \overline 6 \ km/hr}[/tex]

What is the slope of the line that passes through the points (2,0) and (32,-5)?
Write your answer in simplest form.
Answer:
y = -1/6x + 1/3
Step-by-step explanation:
y2 - y1 / x2 - x1
-5 - 0 / 32 - 2
-5 / 30
= -1/6
y = -1/6x + b
0 = -1/6(2) + b
0 = -1/3 + b
1/3 = b
Nick and Natalie regularly change the oil in their vehicles.
The equation y = 4000x represents the number of miles Nick drives while performing x oil changes.
The equation y = 3500x represents the number of miles Natalie drives while performing x oil changes.
What is true of the comparison of the two graphs?
The line representing the number of miles Nick drives while performing x oil changes is less steep than the line
O representing the number of miles Natalie drives while performing x oil changes because he drives fewer miles between oil
changes than Natalie does.
The line representing the number of miles Nick drives while performing x oil changes is steeper than the line representing
o the number of miles Natalie drives while performing x oil changes because he drives farther between oil changes than
Natalie does.
The line representing the number of miles Nick drives while performing x oil changes is less steep than the line
o representing the number of miles Natalie drives while performing x oil changes because he drives farther between oil
changes than Natalie does
O I don't know

point p is the midpoint of de dp 6x+4 and de = 14x -10
Answer:
x = 9
Step-by-step explanation:
A midpoint is found by adding up two numbers and then dividing by 2 (Also known as an average). Therefore, a midpoint marks half of a line. That means that DP is 1/2 of DE. We can now form an equation. 6x + 4 = 1/2 * (14x - 10), making 6x + 4 = 7x - 5 by using the distributive property. Next, isolate x by subtracting by 6x on both sides and adding by 5 on both sides. You would get x = 5 + 4, which means that x = 9.

x-2y=4 going through (1,-6)
Answer:
false
Step-by-step explanation:
Okay so we plug in the values for x and y to make the equation:
1 - 2 x -6 = 4
And then we just solve the left side:
2 x -6 = -12
1 - -12 = 1 + 12 = 13
So this is false

Answer:
-5 ≤ y ≤ 3
Step-by-step explanation:
The range of a function is all the possible values that y can be. We can carefully look at the graph to determine the range. It looks like the greatest y can be is 3, since that's the point on the graph where the function stops going up. Now we can trace down the function to find the least y can be.
It looks like the least y can be is -5, since that's the bottom value of the function. Which option uses says that -5 is the least y can be, and 3 is the greatest y can be?
It looks like -5 ≤ y ≤ 3 is this option, so we can select it as our answer.

Answer:The Indianapolis Motor Speedway is an automobile racing circuit located in Speedway, Indiana (an enclave suburb of Indianapolis) in the United States. It is the home of the Indianapolis 500 and the Verizon 200,[4] and formerly the home of the United States Grand Prix. It is the largest sports venue in the world. It is located on the corner of 16th Street and Georgetown Road, approximately six miles (10 km) west of Downtown Indianapolis.
Constructed in 1909, it is the second purpose-built, banked oval racing circuit after Brooklands and the first to be called a 'speedway'. It is the third-oldest permanent automobile race track in the world, behind Brooklands and the Milwaukee Mile. With a permanent seating capacity of 257,325,[1] it is the highest-capacity sports venue in the world.[5]
Considered relatively flat by American standards, the track is a 2.5-mile-long (4.0 km) rectangular oval with dimensions that have remained essentially unchanged since its construction. It has two 5⁄8-mile-long (1,000 m) straightaways, four geometrically identical 1⁄4-mile (400 m) turns, connected by two 1⁄8-mile (200 m) short straightaways, termed "short chutes", between turns 1 and 2, and between turns 3 and 4.
Step-by-step explanation:
The average displacement of the car would be 33.33 Km
What is displacement?Displacement [x] of an object is the length of the straight line joining the initial and final position of the object. Mathematically, if the velocity of the body is 'v' m/s at an instant of time, then displacement can be written as-
v = dx /dt
x = vdt
∫dx = ∫vdt
Given is the following problem -
A race car completes race in 10 minutes. Its average speed is 200km/hr.
The average displacement of the racetrack would be -
[x] = v x t = 200 x 1/6 = 33.33 Km
Therefore, the average displacement of the car would be 33.33 Km

Answer:

Step-by-step explanation:
12 divided by (2+2/3)^2 =1.6875
1.6875 in a decimal form is 11/16
Answer:
[tex]1\dfrac{11}{16}[/tex]
Step-by-step explanation:
[tex]\left(2 + \dfrac{2}{3}\right)^{2} =\left(\dfrac{2*3}{1*3}+\dfrac{2}{3} \right)^{2}\\\\\\=\left( \dfrac{6}{3}+\dfrac{2}{3} \right)^{2}\\\\\\=\left( \dfrac{8}{3} \right)^{2}\\\\=\dfrac{64}{9}[/tex]
12 ÷ (2 + 2/3)² = 12 ÷ (64/9)
