Step-by-step explanation:
Ariel is training for her pilot's license. The school requires students to learn from the teacher and learn in the simulator. Airplane tutoring costs $105 per hour, and the flight simulator costs $45 per hour. The school requires students to spend 4 more hours in airplane instruction than in the simulator. If Ariel can afford to spend $3870 on training, what is the maximum number of hours of training in an airplane and in a simulator she can afford in getting her license?
Answer: Simulator = 23 hours
Airplane = 27 hours
Step-by-step explanation:
Let the number of hours spent in the simulator be x.
Since the school requires students to spend 4 more hours in airplane instruction than in the simulator. Thai means that the number of hours spent in the airplane will be: x + 4
To determine the maximum number of hours of training in an airplane and in a simulator she can afford in getting her license will then be:
= 105(x+4) + 45(x) = 3870
105x + 420 + 45x = 3870
105x + 45x = 3870 - 420
150x = 3450
x = 3450/150
x = 23
Number of hours spent in simulator = 23 hours.
Number of hours used in airplane = 23 + 4 = 27 hours

PLEASE HELP ME FOR THE LOVE OF GOD
Answer:
Answer my question first!!!! Please, I love god too.
Step-by-step explanation:
what is the y-intercept and x-intercept for the equation -3x - 4 = -5y - 8
Step-by-step explanation:
=> -3x - 4 = -5y - 8
=> 8 - 4 = 3x - 5y
=> 4 = 3x + (-5)y
=> 1 = (3x/4) + (-5y/4)
=> 1 = x/(4/3) + y/(-4/5)
Compare this with x/a + y/b = 1 where a and b are x & y intercepts.
Here,
x intercept = 4/3
y intercept = -4/5
Jessica wants to make pillows for her couch. She has 6 yards of fabric. Each pillow use 2/3 of a yard each. How many pillows can she make?
Answer my answer is 9 :please give me brainliest
Step-by-step explanation:
You divide 6 by 2/3
The number of pillows that she can make will be 9.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Jessica wants to make pillows for her couch. She has 6 yards of fabric. Each pillow uses 2/3 of a yard.
Then the number of pillows that she can make will be given by the division of the numbers 6 and 2/3. Then we have
⇒ 6 / (²/₃)
⇒ 6 x 3 / 2
⇒ 3 x 3
⇒ 9
The number of pillows that she can make will be 9.

The graph of the equation y equals 1/2 x - 3 is shown determine the value of y for the point (4,y)
Answer:y =-1
Step-by-step explanation:
Y=1÷2 x-3 ,y=half (4)-3 ,y=2-3=-1
The table below represents a proportional relationship.
Answer:
y = 3x
Step-by-step explanation:
Note the values of y are 3 times the corresponding values of x, that is
x = 4 → y = 4 × 3 = 12
x = 7 → y = 7 × 3 = 21
x = 10 → y = 10 × 3 = 30
x = 13 → y = 13 × 3 = 39
Thus the equation describing the proportion is
y = 3x

A cab company charges $3 per cab ride, plus an additional $1 per mile driven. How long is a cab ride that costs $20?
Answer:
You will be able to ride 17 miles.
Step-by-step explanation:
So to get into the cab you need to pay 3 dollars. For every mile it will cost you 1 dollar. And you can only spend 20 dollars.
The first step to do is subtract 3 from 20.
This gives us 17.
Now that our cab cost is deducted we can divided 17 dollars by 1 dollar.
17 / 1 = 17.
You will be able to ride for 17 miles

Last year Shaun wiped out 950 times.This year he had a 44% decrease in the
number of times he wiped out.How many times did Shaun wipe out this year?*
Answer:
Shaun wiped out 532 times this year
Step-by-step explanation:
Given
Number of times Shaun wiped out last year = 950
Decrease this year = 44%
In order to find the times Shaun wiped out this year, we have to find 44% of 950 and then subtract it from 950
So,
Decrease in number:
[tex]= 44\%\ of\ 950\\=0.44*950\\= 418[/tex]
The number of times he wiped out this year is:[tex]950-418 = 532[/tex]
Hence,
Shaun wiped out 532 times this year
A bag of marbles contains only the colors blue, yellow, and green.
If the probability of getting a yellow marble is 1/3, and the probability of getting a blue marble is 1/5, what is the probability of getting a green marble?
Answer:
[tex]\frac{7}{15}[/tex]
Step-by-step explanation:
Given parameters:
Marbles in the bag = blue, yellow, and green
Pr(yellow) = [tex]\frac{1}{3}[/tex]
Pr(blue) = [tex]\frac{1}{5}[/tex]
Unknown:
Pr(green) = ?
Solution:
Probability is the likelihood of an event to occur;
For this problem;
Pr(yellow) + Pr(blue) + Pr(green) = 1
[tex]\frac{1}{3}[/tex] + [tex]\frac{1}{5}[/tex] + Pr(green) = 1
Pr(green) = 1 - ( [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{5}[/tex] )
Pr(green) = 1 - [tex]\frac{8}{15}[/tex]
Pr(green) = [tex]\frac{7}{15}[/tex]
