Grant mows lawns for extra money. He mows 9 lawns in 9 hours on Wednesday and 6 lawns In 6 hours on Saturday.

What is the constant of proportionality that relates the total number of lawns mowed, y, to the number of hours mowing lawns, x?

It would be y=x or x=y as we can see that 9 lawns in 9 hrs equal 1 lawn in 1 hr. 6 lawns in 6 hrs equals to 1 lawn in 1 hr as well.

The simplified expression is [tex]27/(16x^6y^8).[/tex]

We have,

To simplify the expression [tex]4(3x^2y^4)^3 / (2x^3y^5)^4,[/tex] we can simplify each part separately and then divide.

Let's simplify the numerator first:

[tex](3x^2y^4)^3 = 3^3 * (x^2)^3 * (y^4)^3 = 27x^6y^{12}[/tex]

Now, let's simplify the denominator:

[tex](2x^3y^5)^4 = 2^4 * (x^3)^4 * (y^5)^4 = 16x^{12}y^{20}[/tex]

Now we can divide the numerator by the denominator:

[tex](27x^6y^{12}) / (16x^{12}y^{20})[/tex]

To divide the variables with the same base, we subtract their exponents:

[tex]27/16 * x^{6-12} * y^{12-20}[/tex]

Simplifying further:

[tex]27/16 * x^{-6} * y^{-8}[/tex]

To make the exponents positive, we can move the variables with negative exponents to the denominator:

[tex]27/(16x^6y^8)[/tex]

Therefore,

The simplified expression is [tex]27/(16x^6y^8).[/tex]

there is 10 fishes in a tank.
1 dies
3 swim away
4 choke on water
2 are breathing
how many fish are in the tank ?

Answers

10

It doesn't say they jumped out of the tank.

Answer:

Im not quite sure but I think it is either 10, cause it says there are 10 fish in the tank. Either that or 8 (ill explain)

Step-by-step explanation:

1 died, but that doesnt mean it was taken out of the tank. 3 swam away, but if they are in a tank they probably just swam to a different part of the tank. 4 choke on water, but that doesnt mean they didnt recover. however, the "2 are breathing" part got me confused since the definition of breathing means taking in air and expelling stuff out...fish "breathe" water so it didnt make sense. So, if you include the 2 breathing fish there are 10, but if u dont there are 8.

A community swimming pool is a rectangular prism that is 30 feet long, 12 feet wide, and 5 feet deep. The wading pool is half as long, half as deep, and the same width as the larger pool.
How many times greater is the volume of the swimming pool than the volume of the wading pool?

Enter your answer as a number, like this: 42
HELLLLPPPP PLEASEEEEEE

Answers

Answer:

The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

Step-by-step explanation:

By definition of rectangular prism, we get the respective formulas for the volumes of the community swimming pool and the wadling pool, respectively:

Community swimming pool

[tex]V_{c} = l\cdot w\cdot h (1)[/tex]

Wading pool

[tex]V_{w} = \left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w (2)[/tex]

Where:

l – Length of the swimming pool, measured in feet.

h – Depth of the swimming pool, measured in feet.

w – Width of the swimming pool, measured in feet.

[tex]V_{c}[/tex] – Volume of the community swimming pool, measured in cubic feet.

[tex]V_{w}[/tex] – Volume of the wading swimming pool, measured in cubic feet.

The ratio of the volume of the community swimming pool to the volume of the wadling pool is:

[tex]\frac{V_{c}}{V_{w}} = \frac{l\cdot w \cdot h}{\left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w} (3)[/tex]

[tex]\frac{V_{c}}{V_{w}} = \frac{1}{\frac{1}{4} }[/tex]

[tex]\frac{V_{c}}{V_{w}} = 4[/tex]

The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

Because of demand, concert tickets that normally sell for 89.99 each are marked up 20%, If Mark wishes to purchase 8 tickets, how much will he pay in total?

20 points will be given

Answers

Answer:$863.92

Step-by-step explanation:20% of 89.99 is 18

89.99x8=719.92

18×8=144

719.92+144=

863.92

Answer:

he will pay 864 dollars in total

Step-by-step explanation:

first we have to find 20% of 90 (i just rounded 89.99 to 90).

20% = 1/5, and 1/5 in decimal form is 0.20.   (you can find the decimal value by multiplying the numerator and denominator by 10/10 and then simplifying it)

0.20 * 90 is 18, so we then add that to 90 making 108.

next, since Mark is buying 8 tickets, we multiply 108 by 8, giving us 864

therefore, 864 is our final answer
