What is scale factor?

Answers

Answer:

Scale Factor is: When you divide the old shape by the new shape (explanation is here)

Step-by-step explanation:

When you have 2 shapes (lets say Y is the old shape and F is the new shape) you would divide the old shape (Y) by the new shape (F)

Another example: lets say shape F is 12 cm and shape Y is 7 cm (F being the old and Y being the new shape) you would divide 12 and 7 to get the answer to that problem

A scale factor is a number which scales, or multiples, some quantity.

The sum 9/10 and 1/32 is less than or greater than 1?

Answers

lets find out! well your trying to find the number that is closest... so lets try.... 160
So , $(9)/(10)$ x 16 = $(144)/(160)$ and $(1)/(32)$ x = $(5)/(160)$
$(144)/(160)$ + $(5)/(160)$ = $(149)/(160)$
so it is less than 1
Hope i helped! :D

Less than 1! If you simplify it the sum is less

Say that you put the set of tiles shown below into a bag and conduct a series of trials in which you draw one tile randomly from the bag, record the color, and replace it. The table below shows the number of times in each set of trials that you drew a blue tile. Round tiles: 5 purple, 6 orange, 2 yellow, 4 red, 1 white, 10 blue, 5 black, 3 green. Trial 1 2 3 4 5 # of Draws 54 36 80 22 75 # of Blues 18 11 20 4 32 Between the theoretical probability that you will draw a blue tile and the experimental probability that you will draw a blue tile, which is greater, and how much greater is it? Express all probabilities as percentages to two decimal places, and express differences by number of percentage points (for example, 12% is 2 percentage points greater than 10%). a. The theoretical probability is 2.78 percentage points greater than the experimental probability. b. The theoretical probability is 1.49 percentage points greater than the experimental probability. c. The experimental probability is 4.06 percentage points greater than the theoretical probability. d. The experimental probability is 2.17 percentage points greater than the theoretical probability.

Answers

The correct answer is (c) The experimental probability is 4.06 percentage points greater than the theoretical probability.

To compare the theoretical probability and the experimental probability of drawing a blue tile, we need to first calculate each one.

Theoretical probability of drawing a blue tile:

Total number of tiles = 5 + 6 + 2 + 4 + 1 + 10 + 5 + 3 = 36

Number of blue tiles = 10

Theoretical probability of drawing a blue tile = number of blue tiles / total number of tiles = 10 / 36 = 27.78%

Experimental probability of drawing a blue tile:

Number of draws in the five trials = 54 + 36 + 80 + 22 + 75 = 267

Number of blue tiles drawn in the five trials = 18 + 11 + 20 + 4 + 32 = 85

Experimental probability of drawing a blue tile = number of blue tiles drawn / number of draws = 85 / 267 = 31.84%

To compare the two probabilities, we subtract the experimental probability from the theoretical probability:

Theoretical probability - experimental probability = 27.78% - 31.84% = -4.06%

The result is negative, which means that the experimental probability is greater than the theoretical probability.

However, we need to express this difference as an absolute value (i.e., without the negative sign) and as a number of percentage points.

The absolute value of -4.06% is 4.06%, and this is the amount by which the experimental probability is greater than the theoretical probability.

Answers

Answer:

x = $(5)/(26)$

Step-by-step explanation:

Given equation:

$(3)/(4)x + (5)/(8) = 4x$

$(3(2)x + 5)/(8) = 4x$ ∵taking GCF 8

$(8 (6x + 5) )/(8)$ = 4x × 8

6x + 5 = 32x ⇒ 5 = 32x - 6x ⇒ 5 = 26x ⇒ x = $(5)/(26)$

1. Cylinder A, B, and C have the same radius but different heights. Put the cylinders inorder of their volume from least to greatest.

Answers

The order of volume from least to greatest is C, B and A.

Step-by-step explanation:

Given:

Three Cylinders namely A, B, and C with different heights have the same radius.

To Find:

Arrange the cylinders from least to greatest with respective to their volume.

Formula for volume of cylinder:

V= $\pi r^(2) h$

i.e V∝ h (for constant radius)

where,

r = radius of cylinder

h = height of cylinder

we see that Volume is directly proportional to height.

Consider, $h_(1), h_(2),h_(3)$ are the heights of cylinder A,B,C respectively, such that;

$h_(1)$ > $h_(2)$ > $h_3}$

And, $V_(1), V_(2),V_(3)$ are the volume of cylinder A,B,C respectively.

So the order of volume will also be,

$V_(1)$ > $V_(2)$ > $V_3}$

Can a rectangle also be a rhombus? Explain.

Answers

Answer:
No

Explanation:
There are some significant differences between the rectangle and the rhombus including:
A rectangle:
1- each two opposite sides are equal
2- all angles are right angles

A rhombus:
1- all sides are equal
2- each two opposite angles are equal but not right

Based on the above differences, we can conclude that a shape can never be a rectangle and a rhombus at the same time

Hope this helps :)

No. A rectangle MUST have 2 pairs of parallel sides and all equal angles.
A rhombus has 2 pairs or parallel sides with 2 pairs of equal angles.
