Answer:it will be -18 gallons

Step-by-step explanation:

Answer:

482 gallons

Step-by-step explanation:

if the total amount in the pool is 500 gallons and it is leaking at -3 gallons per hour then we can solve for how much it has lost in 6 hours by using this equation:

-3(amount loss per hour) x 6(number of hours)= -18

Now we do 500(total)-18(amount lost in 6 hours)= 482 gallons

Which means there are 482 gallons of water left after 6 hours.

Answer:

If we rant their axis of symmetry from least to greatest, it would be:

f(x),h(x), g(x)

Step-by-step explanation:

Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror like reflection of either side of the object.

We can find axis of symmetry with the help of formula:

x = -b/2a

We know that the quadratic equation is written like:

ax^2+bx+c

where a,b are coefficients: c is constant term and x is variable

Now look at the function f(x)= 3x^2

For this function we have a= 3, b =0 , c=0

Put the values in the above mentioned formula:

x = -b/2a

x = - (0)/2(3)

x = 0/6 = 0

Thus the axis of symmetry for f(x) = 0

Now  g(x) = x2 - 4x + 5

a = 1 , b = -4 , c =5

x = -b/2a

x = -(-4)/2(1)

x = 4/2

x = 2

Axis of symmetry for g(x) = 2

h(x) = -2x2 + 4x + 1

a = -2 , b =4 , c=1

x = -b/2a

x = -(4)/2 (-2)

x = -4 /-4

x = 1

Axis of symmetry for h(x) = 1

So if we rant their axis of symmetry from least to greatest, it would be:

f(x),h(x), g(x)

Answer:

When x=1 then the value of y=-2.

Step-by-step explanation:

We are given that a line  on the graph

We have to find the value of  y when x=1

From given graph, the line intersect the x- axis x=3 .Therefore, the point is (3,0).The line intersect y- axis at -3 .Therefor, the point is (0,-3).

We can see that the line passing from (3,0),(2,-1),(1,-2) and (0,-3).

When x=1 then the value of y=-2.

Hence, y=-2 when x=1

Answer:

he's on the 5th floor

Step-by-step explanation:

If he's at 0, then he goes down 4. 0-4=(-4)

Then, He goes up 9 floors from -4.

-4+9=5

Hope this helps!!!

Brady

The elevator starts at street level (0), goes down to -4 and then rises 9 floors to reach the conference center. The sum of -4 + 9 gives 5 which is the floor number for the conference center.

The elevator starts at street level, which we are defining as floor 0. It then goes down 4 floors, so it's at -4. However, it then travels up to the conference center, moving a total of 9 floors. You need to add these 9 floors to where the elevator currently is. So you'll calculate -4 (the current floor number) + 9 (the number of floors it goes up) which equals 5. Therefore, the conference center is on the 5th floor.

Answer:

Step-by-step explanation:

Part a)

Let the volume of water in glass pitcher be 'V'

Now it is given that 1/8 of water is poured in 2 glasses

Thus the volume of water in each glass is

[tex]V'=\frac{1}{2}\times \frac{V}{8}=\frac{V}{16}[/tex]

Part b)

Now it is given that volume of water in each glass is 3 fluid ounces thus to obtain the original volume we euate the volume obtained in part a with 3. Thus

[tex]\frac{V}{16}=3\\\\\therefore V=3\times 16=48ounces[/tex]

Part c)

After pouring out 1/8 water from the orifinal glass the volume of watre that remains in the pitcher euals

[tex]V_{rem}=V-\frac{V}{8}=\frac{7V}{8}[/tex]

Now since 1/4 of the above volume is poured out which euals

[tex]V_{poured}=\frac{1}{4}\times \frac{7V}{8}=\frac{7V}{32}[/tex]

Thus the volume of water that remains euals

[tex]V'_{rem}=\frac{7V}{8}-\frac{7V}{32}=\frac{21V}{32}[/tex]

Applying the value of V we get

[tex]V'_{rem}=\frac{21\times 48}{32}=31.5[/tex]ounces

I believe it is 5:3:1. I'm not completely sure, but that's what I think it is.

The ratio of cups of rice to cups of water in the recipe is 3:5, as there are 3 cups of rice for every 5 cups of water.

To find the ratio of cups of rice to cups of water from the recipe that calls for 5 cups of water and 3 cups of rice, you can simply compare the two quantities directly. The question asked does not require considering additional batches or conversions, so we look at the given amounts.

For every 3 cups of rice, there are 5 cups of water. This can be written as 3:5 or as a fraction \\(\frac{3}{5}\\).

Therefore, the ratio of cups of rice to cups of water is 3:5.

Final answer:

The correct calculation for the total cost to seed an area of 80 feet by 40 feet is $45.00, substantially less than the incorrect $1067 identified due to proper area conversion and cost calculation.

Explanation:

The question about the cost of seeding an area of 80 feet by 40 feet involves calculations for area conversion, determining the number of seeds needed, and calculating the total cost. The initial step involves calculating the area in square feet (80 x 40 = 3200 sq ft) and then converting this area into square yards by dividing by 9 (since there are 9 sq ft in a sq yd), which equals approximately 355.56 sq yds. The bags of grass seed required is then determined by the coverage rate of 1 bag per 25 square yards, yielding about 14.22 bags. However, since you cannot purchase a fraction of a bag, you would need to buy 15 bags of seeds. At a cost of $3.00 per bag, the total cost is $45.00, contrasting significantly with the incorrect calculation provided in the question.

Answer:

It would be week 4 through 6.

Step-by-step explanation:

This is because if you notice that during the first 4 weeks they drop and then week 5 and 6 they raise, which means it is 4 -  6 weeks.

Answer:

The correct option is C) week 4 to week 6.

Step-by-step explanation:

Consider the provided Table.

According to the given information.

Week        Average time on hold

  1                           7

  2                          5                        (Decrease -2)

  3                          3                        (Decrease -2)

  4                          2                        (Decrease -1)

  5                          3                        (Increase +1)

  6                          5                        (Increase +2)

If we observe the table we can find that from week 1 to week 4 average value decrease from 7 to 2.

But from week 4 to 6 the average value starts increasing. The average time  increase from 2 to 5.

Hence, the correct option is C) week 4 to week 6.

Step-by-step explanation:

To determine if the point lies on the line substitute the coordinates into the left side of the equation and if equal to the right side then the point lies on the line

Hence (- 3, 4) lies on the line x + 4y = 13

Answer: B. -5x - 24

Step-by-step explanation:

Simplify 3(2x − 8) – 11x it  is −5x−24

So the answer is B. -5x - 24

The equivalent Algebraic Expression is -5x - 24.

The correct option is (B).

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

3(2x − 8) – 11x

Now, simplifying

3(2x − 8) – 11x

= 6x - 24 - 11x

= -5x - 24

Hence, the equivalent Algebraic Expression is -5x - 24.
