Which figure could be the result of dilating this rectangle with a scale factor between 0 and 1?

Answers

Answer 1
Answer:

Answer:

Option B

Step-by-step explanation:

The figure is shown in the attachment.

The first figure is the main question.

The options are in the second attachment.

We want to chose the figure that could be the result of dilating this rectangle with a scale factor between 0 and 1.

When we dilate a figure with a scale factor between 0 and 1, the size of the figure shrinks but maintains the same orientation as the original figure.

Therefore the correct option is B.
Answer 2
Answer:

Answer:

The sides of the resulting rectangle must be shorter than the original figure.

Step-by-step explanation:

The figures are missing, so I will answer this question in general terms. When a rectangle is dilated by a scale factor between 0 and 1 the resulting rectangle must have shorter sides than the original.

Let's say for example that the original has 2 sides 5 units length and the other 2 sides 8 units length. Then, the resulting figure will have 2 sides less than 5 units length and 2 sides 8 units length, where the proportion 5:8 must still be satisfied.

Answer:

D. 11

Step-by-step explanation:

If the average rate of change on the interval [2,6] is 15 then;

(f(2)-f(6))/(2-6)=15

(f(2)-71)/(-4)=15

Multiply both sides by -4.

f(2)-71=15* -4

f(2)-71=-60

Group similar terms;

f(2)=-60+71

Simplify;

f(2)=11

Answer:

Choice D

Step-by-step explanation:

The average rate of change over the interval [2,6] is simply the slope of the line that joins the points (2,f(2)) and (6,f(6)). To determine f(2) we shall thus be solving the equation;

(f(6)-f(2))/(6-2)=15\n(71-f(2))/(4)=15\n71-f(2)=60\nf(2)=71-60=11

Answers

Commutative property of addition:

a + b = b + a

Associative property of addition:

a + (b + c) = (a + b) + c

Opposite of a sum:

- a - b = - (a + b)

If we look at the options, A and D follow associative property.

B follows commutative property.

C follows opposite of a sum property.

Answer: Associative Property

rebeccas kitten weighed 2 pounds 3 ounces. A month later the kitten weighed 56 ounces. How much weight did the kitten gain in that month ?

Answers

1 pound equals 16 ounces.

Convert the weight from pounds to ounces.

2 pounds 3 ounces:

2 pounds x 16 ounces per pound = 32 ounces

32 + 3 = 35 total ounces


Now find the difference by subtracting:

56 ounces - 35 ounces = 21 ounces

The kitten gained 21 ounces ( 1 pound 5 ounces)
Sh now weighs 3.5 pounds she gained 21 ounces 1.3125 pounds
