A plane flew 720 miles in 6 hours. How many miles did the plane fly in 4 hours?
Answer:
[tex]\huge\boxed{\texttt{480 miles}}[/tex]
Step-by-step explanation:
We can create a ratio here to find the constant of proportionality and use that to find how many miles the plane flew in 4 hours.
We know the plane flew 720 miles in 6 hours. We can create a ratio, represented as a fraction, in the form [tex]\frac{miles}{hours}[/tex] .
[tex]\frac{720}{6}[/tex]
We can now make another ratio where we use a variable for the miles flown in 4 hours.
[tex]\frac{x}{4}[/tex]
Since the ratios are equal, we can create an equation.
[tex]\frac{720}{6}=\frac{x}{4}[/tex]
To find the value of x, let's cross multiply.
[tex]720 \cdot 4 = 2880\\\\2880\div 6 = 480[/tex]
So the plane flew 480 miles in 4 hours.
Hope this helped!
PLZ HELP ME!!!!!I DONT UNDERSTAND
Answer:
(attached image)
Step-by-step explanation:
The graph of y = f(x) is shown. Choose all the true statements.
−2 is a member of the domain of f.
−2 is a member of the range of f.
f(0) > 0
f(2) > 2
Answer:
−2 is a member of the domain of f.
f(0) > 0
Step-by-step explanation:
Statement 1 is TRUE. Domain value includes set of values of x of the function. -2 is plotted on the x-axis on the graph. Therefore, it is a member of domain of f.
Statement 2 is incorrect. Range includes all possible y-values of the function. On the graph, no y-value plotted is -2. Therefore, -2 is NOT a member of the range of f.
Statement 3 is TRUE.
f(0) is approximately 2.2 on the graph. i.e. at x = 0, y ≈ 2.2.
Therefore, f(0) > 0.
Statement 4 is INCORRECT.
f(2) = 1, that is at x = 2, y = 1 as seen in the graph. Therefore, f(2) is not greater than 2.

Step-by-step explanation:
Hank wants to add a row of tile to his kitchen wall. The space is 5.75 feet long. He plans to put a \frac {3}{4} 4 3 –foot yellow tile in the center. He'll fill the rest of the space with blue tiles that are 3 inches long. How many 3-inch blue tiles will he need?
Answer:
He will need 20 3-inch blue tiles
Step-by-step explanation:
Here, the total space to fill is a length of 5.75 ft
The tiles to place at the center has 3/4 ft which is same as 0.75 ft
The length left unfilled will be 5.75 - 0.75 = 5 ft
Now we want to know the number of 3 ft tiles needed to fill up this length;
Mathematically, we know that
1 ft = 12 inches
So 5 ft will be 5 * 12 = 60 inches
So the number of 3 inch tiles needed to fill this length will be 60/3 = 20 tiles
P = a + b + c; solve for b
Answer:
b = P - a - c
Step-by-step explanation:
Step 1: Write equation
P = a + b + c
Step 2: Solve for b
Subtract a on both sides: P - a = b + cSubtract c on both sides: P - a - c = bRewrite: b = P - a - cmaria has three more than twice as many crayons as elizabeth

A square patio has an area of 136 square feet. How long is each side of the patio to the nearest tenth?
Answer:
11.7
Step-by-step explanation:
Answer:
11.7 feet
Step-by-step explanation:
Area finds the length times the width (LxW). In other words, area is how long the first side is multiplied by how wide the second side is. If A=LxW, and we know A is 136, then we know that 136=LxW. This alone isn't enough to find L and W. However, we do know that the patio is a square. Squares have equal sides, so L and W will be the same number. Basically, you need to find the number that equals 136 when it's multiplied by itself. X multiplied by X needs to be 136. You can do this easily with a calculator, if you're allowed to have one. just use the square root function on 136, and be sure to round your answer. If you're not allowed to use a calculator, it's a bit more trial-and-error. Try to see what numbers multiplied by themselves get close to 136, and narrow it down from there (ex. if 11 is too little and 12 is too much, the answer is between 11 and 12). You can also look up video tutorials for how to find a square root without a calculator, or use other study platforms. I hope this helps, and feel free to ask me any questions!! :)
p(x)=6x-5. p(x)=13 what is x?
Answer:
x=3
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
p(x) = 6x - 5 but p(x) = 13
=> 6x - 5 = 13
<=> 6x = 18
<=> x = 18 : 6 =3

3x – 1 = 2(x + 34)
what is the answer in feet and inches?
Answer:
inches:-69
feet:-5 9/12 (-5 3/4 simplified)
Step-by-step explanation:
Write out the equation and distribute.
3x – 1 = 2(x + 34)
3x - 1 = 2x + 68
Get rid of the variable on one side first (it makes solving the equation less complicated.)
3x - 1 = 2x + 68
-3x -3x
-1 = -x + 68
Subtract 68 on both sides.
-1 = -x + 68
-68 -68
-69 = x
I'm guessing that the answer in feet and inches would be...
inches:-69
feet:-5 9/12 (-5 3/4 simplified)
I'm not sure how feet and inches can be negative, but that's what I got for the answer...hope this helps! Have an amazing day C:

Help Me Please This Was Due Saturday The 25th!
Answer:
the last box is 3
Step-by-step explanation:
Answer: 4
Step-by-step explanation: If you multiply 3/5 by 3/3, it will turn into 9/15. If you multiply -1/3 by 5/5, it will turn into -5/15. Since it is a negative, you will have to subtract. 9-5 is 4.

which angles of transformed figures have the same measure as ∠c in figure ABC?
Answer:
All of them
Step-by-step explanation:
It looks like the transformations that occurred here are reflections, translations, and rotations which are all rigid transformations. Rigid transformations conserve the angle measurements and side lengths of the corresponding image to the original one.
James and Tyree have new jobs at YumYum’s Ice Cream Parlor. James is Tyree’s manager. In their first year, James will be paid $14 per hour and Tyree will be paid $7 per hour. They have been told that after every year with the company, they will each be given a raise of $2 per hour. Is this realationship porprotional?
Answer:
No.
Step-by-step explanation:
(h represents the hours; y represents years; m represents the total money they'd get!)
If you put this into an equation, for James it would be:
14h +2y = M
For Tyree, it would be:
7h + 2y = M
Because the numbers don't match up, the answer is no. The relationship is not proportional.
