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

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.

Step-by-step explanation:

Find the volume with the formula, V = (4/3)πr³.

Step-by-step explanation:

2= 2/1

so you do 2/1 x 5/8

then you do 2 x 5 over 1 x 8 and you answer will be 10/8 or 1 2/8

Step by step solution :Step  1  :Equation at the end of step  1  : (((3•(x2))•(y4))3) 4•—————————————————— ((2x3•(y5))4) Step  2  :Equation at the end of step  2  : ((3x2 • (y4))3) 4 • ——————————————— 24x12y20 Step  3  : 33x6y12 Simplify ———————— 24x12y20 Dividing exponential expressions :

3.1    x6 divided by x12 = x(6 - 12) = x(-6) = 1/x6

Dividing exponential expressions :

3.2    y12 divided by y20 = y(12 - 20) = y(-8) = 1/y8

Equation at the end of step  3  : 27 4 • —————— 16x6y8 Step  4  :Final result : 27 ————— 4x6y8

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]

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.

I really hope this helps :)

Answer:

I believe the answer is (4 * 5 +1) = 21

Step-by-step explanation:

The fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.

To guarantee that you have picked 5 beads of the same color, you need to ensure that you have at least 4 beads from each of the 5 colors.

To calculate the fewest number of beads you must pick, we can consider the worst-case scenario where you have picked the maximum number of beads from each color without having 5 of the same color.

In this scenario, you would have 4 beads from each color, which totals 4 * 5 = 20 beads.

However, to guarantee that you have 5 beads of the same color, you need to pick one more bead from each color, which is an additional 5 beads.

Therefore, the fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.

The answer is c.

Step-by-step explanation:

Rate of change means slope, in C, the slope is 6. Whenever you see an equation like that and a number with x after it, that's the slope, or rate of change. On the graph, the rate of change is -3, on answer choice C, the slope is -6.
