Answer:

<u>Option B: square is the answer.</u>

Step-by-step explanation:

Rotational symmetry occurs when any given shape or pattern can be rotated around a central point and it remains the same throughout. Many shapes like- rectangles, squares, circles, regular polygons have rotational symmetry. The point around which the rotation occurs is the center of the shape.

Here, out of the given four figures, square has a rotational symmetry as it will remain the same throughout rotation.

Rest options A,C and D will not retain the same shape throughout the rotation of 360 degrees, that is why these are wrong options.

I think around 17 min...

Step-by-step explanation:

there is 60 sec in a minute so divide 60/8 , divide 60/6, then add them together....

60/8= 7.5 and 60/ 6=10

so 7.5+10 = 17.5

Set Q contains 20 positive integer values. The smallest value in Set Q is a single digit value and the largest value in Set Q is

Lerok [7]

Answer: possible values of Range will be values that are >=91 or <=998

Step-by-step explanation:

Given that :

Set Q contains 20 positive integer values. The smallest value in Set Q is a single digit value and the largest value in Set Q is a three digit value.

Therefore,

given that the smallest value in set Q is a one digit number :

Then lower unit = 1, upper unit = 9( this represents the lowest and highest one digit number)

Also, the largest value in Set Q is a three digit value:

Then lower unit = 100, upper unit = 999 ( this represents the lowest and highest 3 digit numbers).

Therefore, the possible values of the range in SET Q:

The maximum possible range of the values in set Q = (Highest possible three digit value - lowest possible one digit) = (999 - 1) = 998

The least possible range of values in set Q = (lowest possible three digit value - highest possible one digit value) = (100 - 9) = 91

For her presentation on the Wonders of the World, Mary baked a square pyramid-shaped cake as pictured below. The slant height of

miskamm [114]

Answer:

volume = 195.52 in³

Step-by-step explanation:

given data

slant height of the cake = 10 inches

base length = 8 inches

solution

we know that volume pyramid is express as

volume = $\frac{A^2\times h}{3}$ ..............1

here

we use pythagoras for height

hypotenuse² = side1² + side2²

put here value with other side is half of a square side

10² = h² + 4²

solve it we get

h = 9.165 in

so put here value in equation 1 we get

volume = $\frac{8^2\times 9.165}{3}$

volume = 195.52 in³

It’s number 5 please help

Oksanka [162]

8x+100 with x representing the number of classes attended. For Ms.Wiggins, the equation would be 8(18)+100. You would multiple 8 x 18 getting 144+100. You add 144+100 to get $244 for Ms.Wiggins.
