Answer:

A

Step-by-step explanation:

Since each star is worth 50 points, if 5 stars are zapped that would convert to 250 points. Each level the number of stars increase by 5, level 6 would have 45 stars and so on.. With level 10 having 65 stars to complete.

Pls help!! Find the volume of the flower vase. Round to the nearest tenth.
Contact [7]

Answer:

Volume = 1596.2 cubic cm

Step-by-step explanation:

Volume = volume of box - volume of cylinder

Volume = (LxWxH) - 1/3 (pi * r^2 *h)

Volume = (10 x 12 x 20) -1/3 (3.14 x 8^2 x 12)

Volume = 2400 - 803.8

Volume = 1596.2 cm^3

UNO [17]

Answer:

<em>2 solutions</em>

Step-by-step explanation:

Given the expression

2m/2m+3 - 2m/2m-3 = 1

Find the LCM of the expression at the left hand side:

2m(2m-3)-2m(2m+3)/(2m+3)(2m-3) = 1

open the bracket

4m²-6m-4m²-6m/(4m²-9) = 1

Cross multiply

4m²-6m-4m²-6m = 4m²  - 9

-12m = 4m²  - 9

4m²  - 9+12m = 0

4m² +12m-9 = 0

<em>Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2</em>

Olenka [21]

Answer:

4.0506100 x 10^-1

Step-by-step explanation:

Because all you need to do is move the decimal point to the right once, you write 10^-1 to show that to get back to the original number, you just multiply 4.0506100 by -0.1

Gina looked at the architectural plan of a room with four walls in which the walls meet each other at right angles. The length o
Lerok [7]

For a better understanding of the solution provided here, please find the diagram attached.

In the diagram, ABCD is the room.

AC is the diagonal whose length is 18.79 inches.

The length of wall AB is 17 inches.

From the given information, we have to determine the length of the BC, which is depicted a x, because for the room to be a square, the length of the wall AB must be equal to the length of the wall BC.

In order to determine the length of the wall BC, or x, we will have to employ the Pythagoras' Theorem here. Thus:

x=\sqrt{(AC)^2-(AB)^2}

x=\sqrt{(18.79)^2-(17)^2}\approx\sqrt{64.06} \approx8

Thus, BC\approx 8 inches

\therefore AB\neq BC and hence, the given room is not a square.
