Jason poured 1 gallon 1 quart of water into an empty 2-gallon bucket. How much more water can be added to reach the bucket's 2-gallon capacity?
Answer: 3 quart
Step-by-step explanation:
Given
Jason poured 1 gallon 1 quart of water into an empty 2 gallon bucket
1 gallon can be written as 4 quart
So, 2 gallon can be written as 8 quart
Subtract 1 gallon 1 quart(5 quart) from 2 gallon(8 quart) to get the volume added
[tex]\Rightarrow 8-5\\\Rightarrow 3\ \text{quart}[/tex]
So, 3 quart of water must be added to reach 2 gallon capacity.

Here is part of a timetable for the Paris to Montpellier express train service.
The average speed of the 20 07 train from Paris is 224 km/h. Work out the distance this train travels from Paris to Montpelli
Answer:
772.8 km
Step-by-step explanation:
Speed is the rate of change of distance. Speed is the ratio of distance travelled to time taken. Average speed is the ratio of the total distance travelled to the total time taken, it is given by:
Average speed = Total distance / total time
The 20 07 train leaves Paris at 20:07 and reaches Montpellier at 23:34. This means that the total time taken is 3 hours 27 minutes, that is 3.45 hours.
Given that average speed is 224 km/h, hence:
Average speed = total distance / total time
224 km/h = total distance / 3.45 h
total distance = 224 * 3.45 = 772.8 km

Answer:
[tex] \large \boxed{ \boxed{ \tt x \geqslant 2 \: \: is \: \: the \: \: domain \: \: of \: \: function}}[/tex]
Step-by-step explanation:
We are given the square root function below:
[tex] \large{g(x) = \sqrt{x - 2} }[/tex]
Recall that domain is the set of all x-values and that a number inside the square root cannot be negative.
From the given square root function above, substituting x >= 2 gives a positive output. But if we substitute x < 2, evaluating the numbers inside result in negative number in the square root which does not exist in Real Number.
Hence,
[tex] \large{y = \sqrt{x - a} }[/tex]
And thus, the domain is
[tex] \large \boxed{x \geqslant a}[/tex]
Since if x < a, the output would become an imaginary number.
From the given function,
[tex] \large{g(x) = \sqrt{x - 2} }[/tex]
From the form of sqrt(x-a) where domain is a-term which is 2.
Since a = 2, and thus
[tex] \large \boxed{x \geqslant 2}[/tex]
Solve for x xx. Your answer must be simplified. − 18 < 9 x −18<9x
Answer:
x > -2
Step-by-step explanation:
-18 < 9x is the inequality, right?
We'll divide both sides by 9 to isolate x
-2 < x or x > -2

Angle A terminates in the fourth quadrant with cosA= 4/5. The exact value of A is?
Answer:
324.13°
Step-by-step explanation:
Applying,
cosA = 4/5
To find the value of A, we find the inverse of the cosine of both side,
(cosA)cos⁻¹ = cos⁻¹(4/5)
A = cos⁻¹(0.8)
A = 36.87° (First quadrant)
The above value of A is its value in the first quadrant
To find the value of A in the fourth quadrant, we use the expression
∅₄ = 360-∅₁............... Equation 1
Where ∅₄= value of A in the fourth quadrant, ∅₁ = value of A in the first quadrant.
Therefore,
∅₄ = 360-36.87
∅₄ = 324.13°
Hence the value of A in the fourth quadrant is 324.13°
An apartment cost $870 per month to rent. The owner raises the price by 20% and then gives a discount of 8% to returners who sign an 18 month lease. How much less the renters who signed the 18 month lease pay per month to rent the apartment
Answer:
$34.8
Step-by-step explanation:
Given data
Cost of apartment= $870 per month
increase= 20%
Discount= 8%
Let us find the amount of increase
=20/100*870
=0.2*870
=$174
New cost = 870+174
=$1044
New cost of apartment for 18 month
=1044*18
=$18792
He gave them 8% discount
=8/100*18792
=0.8*18792
=$15033.6
Hence the monthly fee will be
=15033.6/18
=$835.2
Therefore the difference in price is
=870-835.2
=$34.8
Write the equation of the line through (8,-2); m = 0
ANSWER ASAP PLEASE!!
Answer:
y = -2
Step-by-step explanation:
The formula for point-slope is as follows:
y - y1 = m(x - x1)
We are given the slope, m, or 0, and we are given the point (8, -2), which we can substitute into the point (x1, y1):
y + 2 = 0(x - 8)
y + 2 = 0
y = -2
Badwater Basin, California, has the lowest elevation in North America. It is 279 feet below sea level. New Orleans, Louisiana, is 7 feet below sea level.
Answer:
272 feets
Step-by-step explanation:
Badwater Basin = 279 feets below sea level = - 279 feets (relative to sea level)
New Orleans = 7 feets below sea level = - 7 feets (relative to sea level)
Hence,
New Orleans is higher Than Badwater Basin by :
279 feets - 7 feets
= 272 feets

Jerry 1/5 of his allowance on a book and 3/8 of the remainder of his allowance for $12.00. Calculate: A.Jerry's allowance B.The cost of the book C.The cost of the pen
Answer:
Allowance = $24
Cost of book = $4.8
Cost of pen = $7.2
Step-by-step explanation:
[tex]Let \ his \ allowance\ be\ x\\\\\frac{1}{5} \ of \ x \ on\ books\\\\\frac{3}{8} \ of \frac{4}{5} \ of \ x\ on \ pen\\\\Balance \ in \ hand = 12[/tex]
[tex]x = \frac{1}{5}x + (\frac{3}{8} \times \frac{4}{5})x +12\\\\x = \frac{1}{5}x + \frac{12}{40} +12\\\\x =\frac{1}{5}x + \frac{3}{10} +12\\\\x - \frac{1}{5}x - \frac{3}{10} =12\\\\\frac{10x - 2x -3x}{10} = 12\\\\\frac{5}{10}x = 12\\\\5x = 12 \times 10\\5x = 120\\x = 24[/tex]
[tex]cost \ of \ book = \frac{1}{5} \times x = \frac{1}{5} \times 24 = 4.8\\\\cost \ of \ pen = \frac{3}{8} \times \frac{4}{5} \times x = \frac{3}{8} \times \frac{4}{5} \times 24 = 7.2[/tex]

Four coins are tossed in succession. What is the probability of getting all heads?
1/4
1/2
1/16
Answer:
1/16
Step-by-step explanation:
There is a 1/2 chance to flip a heads.
So, in this case, we would multiply 1/2 four times in reference to the coins being flipped a total of 4 times to find its probability.
1/2 x 1/2 x 1/2 x 1/2 = 1/16
Thus, there is a 1/16 chance that you'd get heads four times in a row.

depth at point B = 5 m
Step-by-step explanation:
y = -(2/5)x - 1
Point C is located 10 m from the origin O which means that x = 10. Using this value in our equation,
