the boeing 747 airplane is 250 feet in length. If a model of this airplane is 8 inches long, what scale was used to create the model.
please help!!!
Answers
answer: The wingspan is 36 m.
Using a proportion to solve this, we write the scale factor as a ratio first: 19/38, since 19 is the size of the model's length and 38 is the real length. For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:
19/38 = 18/x
Cross multiply:
19*x = 38*18
19x = 684

is -5.1 greater than -4?
Answers
Answer:
-4 is greater than -5.1.
Answer:
No
Step-by-step explanation:
In integers, it's almost backwards. If you are looking at a scale, -4 would be further up, or closer to zero than -5.1.
So, if you are looking at negative numbers, basically, the closer the number is to zero, the greater it is.

Given the lines shown here, what are two possible equations for this system of equations?
Answers
Answer:
Blue line: either y=1/4x+1, y=1/5x+1, or y=1/6x+1 (depending on how u see where it intercepts in the x-axis.
Black line: either y=1/4x-10, y=1/5x-10, or y=1/6x-10 (depending on how u see where it intercepts in the x-axis.
Step-by-step explanation:
Well because they don't have the numbers it's hard to tell. But they will have the same slope which makes them parallel. So the Y intecept for the blue line would be 1 if it's how it's shown. Then the slope would be one over 4,5 or 6. Then again I cannot see numbers there so... anyways, the equation for the blue line would be about y=1/5x+1. For the black line, I think it intercepts on the -10 for the Y. So if the slope is the same so that they can be parallel then it would be y=1/5x-10. (WARNING: This answer might change if they give you the numbers of the actual line. THIS IS JUST AN ESTIMATE!! THEY ARE POSSIBLE ONES!!!!!) But remember when lines are parallel they have the same slope but different Y-intercept! Hope this helped a bit... ask me if u have any questions.
cause y=mx+b (m is the slope which is rise over run) (b is the y-intercept)

Answer:
no, because the number line shows the arrow going backward, so now we know its subtraction, so you're going to count backward until you reach the number we are looking for so 7/8 minus 2/8 equals 5/8.

Before we write 3 paragraphs, we need to solve the equation ourselves using the order of operations.
Order of Operations: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. (PEMDAS)
3 · (10 - 2) + 4²
3 · (8) + 4²
3 · (8) + 16
24 + 16
40
Finally, here's the prompt:
The requirements of the prompt are to show step-by-step how to solve the problem and to explain the order of operations in 3 paragraphs.In order to solve the equation, we have to understand the order of operations, which is the order used in solving expressions. The order of operations are parenthesis, exponents, multiplication, division, adding, and finally subtracting. It's usually abbreviated to 'PEMDAS'.
The first step of solving the equation is solving what's in the parenthesis, which is 10 - 2. By subtracting, you should get 8. The second step is solving the exponents, which is 4 to the second power. to do that, we multiply 4 by itself, so we should get 16. Now, for the third step, we have to multiply 3 x 8 before we add 16 so we follow the order of operations. After multiplying 8 x 3, you should get 24.
Now, all that's left is to add 24 and 16. Our answer should be 40. That's how you solve the equation using order of operations. In this equation, we only used parenthesis, exponents, multiplication, and addition. Even though there was no division or subtracting (besides subtracting in parenthesis), we still follow the order of operations.
Answer: I did Parenthesis, I subtracted 10-2, that gave me 8. Next I did exponents, I multiplied 4 twice or to the 2nd power. That gave me 16. Then I multiplied 3 and 8 and that equals 24. After that the only thing left to do is add 16 and 24 which equals to 40. That's how I got my answer by using PEMDAS. I followed the order of operations even though I didn't have to use division.

Georgia practiced for her dance recital for 3/4 of an hour on Monday, 3/8 of an hour on Tuesday, and 5/6 of an hour on Wednesday. How much longer did she practice on Monday than on Tuesday?
Answers
Answer:
The Answer is 22.5
Step-by-step explanation:
because 3/4 is 45 minutes.'
and 3/8 is 22.5 minutes.
45-22.5=22.5 minutes different.
3/8 longer or 2 times longer or 22.5 minutes longer on Monday depending on the type of answer they want.
EXPLANATION:
3/8 longer or 2 times longer Explanation is:
Gotta find common denominator
Common denominator is 8
6/8 on Monday and 3/8 on Tuesday so difference of 3/8 or twice as long
22.5 Minutes Longer explanation is:
3/4 of an hour is 45 minutes (60/4=15x3=45) 3/8 of an hour is 7.5 minutes (60/8=7.5x3=22.5)
So 45-22.5= 22.5 minutes longer on Monday
