Which plane is closer to the base of the airport tower? Explain.
Write the distance for each plane to the nearest 10th
Answer:
Plane B is closer.
Step-by-step explanation:
Plane B is closer.
The distance for Plane A is 7.9 km.
The distance for Plane B is 7.4 km.
Step-by-step explanation:
To find the distance to the tower, altitude must be converted to kilometers. Each 1000 ft is 0.3048 km, so the heights of the planes are ...
-- Plane A: (20 thousand ft)*(0.3048 km/thousand ft) = 6.096 km
-- Plane B: (8 thousand ft)*(0.3048 km/thousand ft) = 2.4384 km
The Pythagorean theorem can be used to find the distance from each plane to the tower:
-- distance = √((ground distance)² + (height)²)
-- Plane A distance = √(5² +6.096²) ≈ √62.16 ≈ 7.9 . . . km
-- Plane B distance = √(7² +2.4384²) ≈ √54.95 ≈ 7.4 . . . km
The distance for Plane B is shorter, so Plane B is closer to the tower.
Can someone help me D: it's math (if you don't know, I'm terrible at math, so please help lol)

So the basic idea of this type of math is if you know how to multiply you are gonna KEEP CHANGE and Flip. Keep the number chand the division sign to a multiplication sign or vise versa the Flip the fraction where the denominator is offically the numerator.
Example 1:
4 divided by 1/2
KEEP CHANGE FLIP
4 x 2/1 =8/1 or 8
See its that simple!
Here is you math

a + 6.6 = 12.6 helpp please !
Answer:
it is 6
Step-by-step explanation:
because if you subtract 12.6 - 6.6 = 6 so 6 + 6.6 is 12.6
Answer:
A = 6
Step-by-step explanation:
To solve the equation A + 6.6 = 12.6, you need to isolate the variable "A," which represents an unknown value.
Subtract 6.6 from both sides of the equation:
=> A + 6.6 - 6.6 = 12.6 - 6.6
Simplifying this equation gives:
=> A = 6
Therefore, the solution to the equation A + 6.6 = 12.6 is A = 6.

Curt’s kite is 48 yards above the ground, and directly above a tree. The length of the string from Curt to the kite is 52 yards. How far is Curt from the tree?
Answer:
he is 4 feet
Step-by-step explanation:
52 minus 4 is 48 so...
HELP THIS IS DUE TODAY?!
52.5 Yards (yd).
7 + 7 = 14
14 + 14 = 28 ( 10 + 10 + 4 + 4)
14 + 28 = 42 (4 - 2 + 8 = 10 + 20 + 10)
42 + 10.5 = 52.5
⚠⚠ if you need to multiply this by itself (squaring is the proper name) then the answer is 2756.25 Yards.

Solve the system of equations by substitution
Answer:
x = 4
y = 30
Step-by-step explanation:
Since y = 8x - 2, substitute into 2nd equationThis gives you 3x + 8x - 2 = 42Add 2 to both sides11x = 44Divide both sides by 11x = 4Put this value into either equationI choose the first oney = 8x - 2 = 8 × 4 - 2 = 32 - 2 = 30Answer:
x=4
y=30
Step-by-step explanation:
First re-write the system like this:
[tex] - 8x + y = - 2 \\ 3x + y = 42[/tex]
Now substitute them together:
[tex] - 11x = - 44[/tex]
So
[tex]x = 4[/tex]
put x=4 in one of the equations
[tex]3(4) + y = 42 \\ \\ y = 30[/tex]
so
x=4
y=30
I am going into the hard math now, Will you please help me understand this problem?
Answer:
17.6
Step-by-step explanation:
I like to approach surface area problems by solving the invdividual 2d shapes on the figure.
First we will solve the triangle(s)
1/2xbh=a
1/2x2=a
1=a
As there is another triangle reflected behind it we so far have 2 units.
Now we solve the 3 rectangles in the figure
3x2.2 = 6.6 (first slanted rectangle)
3x1= 3 (bottom rectangle)
2x3=6 (side rectangle)
Now we add up all our units
2 + 6 + 3 + 6.6
17.6 = SA

Joshua wants to purchase a new cell phone, but he does not have enough money in his bank account to pay for one. Which of these is not an option for Joshua?
Answer:
The answer is the debit card.
Step-by-step explanation:
Because a debit card takes money straight from your bank account and if he doesn't have enough money in his bank account he can't pay for it. Does that make sense?? If not let me know and I will explain it better.
Answer:
Debit card
Step-by-step explanation:
He doesn't even have enough money and debit cards base your spending limit on how much money you have in your account.

The first sequence rule is multiply by 4 starting from 7. The second sequence rule is add 5 starting from 8. What is the first number that appears in both sequences?
Answer: The first number that appears in both sequences is 28.
Step-by-step explanation:
Let's write down numbers from each of the sequences
Sequence 1) We need to start from 7 and multiply 4
7x4=28, 28x4=112
The sequence is 7,28,112...
Sequence 2) We need to start from 8 and add 5
5+8=13, 13+5=18, 18+5=23, 23+5=28
The sequence is 8,13,18,23,28...
They both have 28
28 is the first number that appears in both sequences.
multiply by 4 starting from 7
First sequence: 7 * 4 = 28 *4 = 112 * 4 = 448add 5 starting from 8
Second sequence: 8 + 5 = 13 + 5 = 18 + 5 = 23 + 5 = 28Give your answer in minutes.
Answer:
38 minutes
Step-by-step explanation:
This is simple because can add 17 minutes to get to 11 AM
There, we can just add 21 more minutes to get to 11:23 AM!
17+21=38!

Thirty percent of the beads in a bag are blue. One bead is randomly chosen and replaced. Then a second bead is chosen. What is the probability that neither is blue?
Answer:
Answer: 12%
Step-by-step explanation:
To find the probability of picking not only a sphere but one that is blue as well, you need to multiply the probabilities of both events because this would show the probability of getting the second event if the first is gotten:
= Probability of sphere * Probability that sphere is blue
= 40% * 30%
= 12%
