A class is having a water balloon tossing contest. There is a large tub of water. Gavin uses 3 1/5 quarts of water to fill some balloons, and Quinley uses 6 1/2 quarts to fill more balloons. Find the total change of volume of water in the tub
We want to find the total change in the volume of water of a tub, given that we know how much water is used.
The change in volume is: -(9 + 7/10) quarts.
To find the change in volume, we need to find the total volume of water used.
We do know that:
Gavin uses (3 + 1/5) quarts of waterQuinley uses (6 + 1/2) quarts of water.The total amount used is the sum of the two quantities above, we get:
(3 + 1/5) quarts + (6 + 1/2) quarts
(3 + 6 + 1/2 + 1/5) quarts
(9 + 7/10) quarts.
So the change in volume is related to this, and we should write:
Final Volume - Initial Volume = -(9 + 7/10) quarts.
Where the negative sign is because at the end we have less volume than at the beginning.

−22x+121
After substitute y=25. we get,
x

−22x+121−25=0
⇒x

−22x+96=0
⇒(x−16)(x−6)=0
⇒x=16,x=6
∴ two points are A,B are (16,25),(6,25).
Distance between A and B is

What is the value of x in the equation 5 − 3x = −7?
Step-by-step explanation:
5 − 3x = −7
=> 5 + 7 = 3x
=> 12 = 3x
[tex] = > x = \frac{12}{3} [/tex]
=> x = 4 (Ans)
Given :
5 − 3x = −7⠀
To Find :
The required value of x .⠀
Solution :
[tex]\qquad \sf \: { \dashrightarrow 5 - 3x = - 7}[/tex]
⠀
Adding (–5) to both sides :
[tex]\qquad \sf \: { \dashrightarrow 5 + ( - 5) \: − 3x = −7 + ( - 5)}[/tex]
[tex]\qquad \sf \: { \dashrightarrow \: − 3x = - 12}[/tex]
⠀
Dividing both sides by 3 :
[tex]\qquad \sf \: { \dashrightarrow \dfrac{ - 3x}{3} = \dfrac{ - 12}{3} } [/tex]
[tex]\qquad \sf \: { \dashrightarrow − x = −4}[/tex]
⠀
Cancelling (–) from both sides we get :
[tex]\qquad {\pmb {\bf{ \dashrightarrow x = 4}}} \\ [/tex]
⠀
Therefore, The required value of x is 4.

To make papier-mâché, Emma uses 3/4 cup of white school glue for each batch. For a big project, she will make 11 batches of papier-mâché. Emma has half of 1-gallon bottle of white school glue. Does Emma have enough glue?
Emma will not have enough glue since she'll have 10 2/3 rather than 11 batches.
Note that 1 gallon = 16 cups
Since Emma has half of 1-gallon bottle of white school glue, this means that she has 1/2 × 16 = 8 cups
Since Emma uses 3/4 cup of white school glue for each batch, therefore the number of batches that van be made with 8 cups will be:
= 8 ÷ 3/4
= 8 × 4/3
= 10 2/3
Therefore, Emma will not have enough glue since she'll have 10 2/3 rather than 11 batches.

sin^2 x - 2sinx + 2 = sin^2 3x
Recall the triple angle identity for sine:
sin(3x) = 3 sin(x) cos²(x) - sin³(x)
… = 3 sin(x) (1 - sin²(x)) - sin³(x)
… = 3 sin(x) - 4 sin³(x)
So the equation is equivalent to
sin²(x) - 2 sin(x) + 2 = sin²(3x)
sin²(x) - 2 sin(x) + 2 = (3 sin(x) - 4 sin³(x))²
sin²(x) - 2 sin(x) + 2 = 9 sin²(x) - 24 sin⁴(x) + 16 sin⁶(x)
16 sin⁶(x) - 24 sin⁴(x) + 8 sin²(x) + 2 sin(x) - 2 = 0
or, by replacing y = sin(x),
16y ⁶ - 24y ⁴ + 8y ² + 2y - 2 = 0
By inspection, y = 1 is a root, since
16 - 24 + 8 + 2 - 2 = 0
so we get one family of solutions,
sin(x) = 1 ===> x = arcsin(1) + 2nπ = π/2 + 2nπ
Now suppose y ≠ 1. Dividing both sides of the sextic equation by y - 1 then gives
(16y ⁶ - 24y ⁴ + 8y ² + 2y - 2)/(y - 1) = 0
16y ⁵ + 16y ⁴ - 8y ³ - 8y ² + 2 = 0
Unfortunately, the remaining roots can only be obtained through numerical methods. Using a calculator, you would find
y ≈ -1.127
y ≈ -0.475 ± 0.368i
y ≈ 0.539 ± 0.127i
But if you're solving over the reals, you can ignore these solutions. Remember that sin(x) is bounded between -1 and 1, and its value goes outside this interval only when x is complex.

A rectangular field is five times as long as wide. If the perimeter of the field is 780 feet, what are the dimensions of the field?
Answer:
65 and 325
Step-by-step explanation:
(l+w)*2 = 780
l+w = 390
l = 5w
5w + w = 390
6w = 390
w = 65
length = 325
It is first down in a football game. Your team has the ball at your 25-yard marker, and the play is a successful run for 6 yards. A number line from ten to forty with labels at ten, twenty, thirty, and forty. Between each pair of labeled points are four tick marks. Where does the ball end up? Where is the ball relative to where it started? Use the number line to find the answer. Enter the correct answers in the boxes.
Using the theory of Number line in location linear distances, the final position of the ball is 31 yards while the relative position is 6 yards to the right of its initial position.
Initial position of the ball = 25 yards Distance moved by the ball = 6 yardsFinal position of the ball = Initial position + distance moved
Final position = (25 yards + 6 yards) = 31 yards
Final position of the ball relative to its starting position :
Since the ball moves to towards the right of the starting position, then the new position of the ball is 6 yards to the right of its starting position.Therefore, the final position of the ball is 31 yards and it is 6 yards to the right of its starting position.
