Answer:

7.5×10^4

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps <3

Quadrilateral A has side lengths 6, 9, 9, and 12. Quadrilateral B is a scaled copy of Quadrilateral A, with its shortest side of

Varvara68 [4.7K]

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new location is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

a) The scale factor from Quadrilateral A to Quadrilateral B = smallest side length of side B / smallest side length of side A = 2 / 6 = 1/3

Scale factor = 1/4= 1 / 3

The side length of 6 in A corresponds to a side length of 2 in B

Side length of B that corresponds with side length of 9 in A = scale factor * 9 = 1/3 * 9 = 3

The side length of 9 in A corresponds to a side length of 3 in B

Side length of B that corresponds with side length of 12 in A = scale factor * 9 = 1/3 * 12 = 4

The side length of 12 in A corresponds to a side length of 4 in B.

c) perimeter of Quadrilateral B = sum of side lengths of quadrilateral B = 2 + 3 + 3 + 4 = 12 units

In order to store paint, a factory has purchased a cylindrical tank that is 6 feet across and 9 feet deep. What is the maximum n

SOVA2 [1]

Answer:

254 cubic feet.

Step-by-step explanation:

It is given that the a cylindrical tank is 6 feet across and 9 feet deep. It means

Diameter of cylinder = 6 feet

Radius of the cylinder = 6/2 = 3 feet

Height of the cylinder = 9 feet

The volume of a cylinder is

$V=\pi r^2h$

where, r is radius and h is height of the cylinder.

Substitute r=3 and h=9 in the above formula.

$V=\pi (3)^2(9)$

$V=81\pi$

$V=254.46900$

We need to find the maximum number of cubic feet. So approx the value to a whole number.

$V\approx 254$

Therefore, the maximum number of cubic feet of paint the tank will hold is 254 cubic feet.

1. A, Because you're able to take any point on that plane and use it to name it.
2. b (not really sure how to explain....)
3. not sure.
4. d, since e is under plane p

In the 500 spin test, 4 was chosen 121 times. This mean it was chosen 121 times out of 500, or 121/500.

Now, we need to convert this into a percent. We do this by dividing the numerator by the denominator, and multiplying the result by 100.

121/500 * 100 = 24.2, so the probability of spinning a 4 is 24.2%.
