Answer:

4050 cm²

Step-by-step explanation:

This is a question of scale factors:

The radius of the larger circle is 9× that of the smaller circle;

This is the linear scale factor of the enlargement of the smaller to larger circle;

The scale factor of the area pertains to 2 dimensions so the scale factor will be the square of the linear scale factor, which is:
9² = 81

The area of the larger circle is found by the area of the smaller circle multiplied by this number:
50 × 81 = 4050

Write the inequality shown by the graph.
OLga [1]

Answer:  A

Step-by-step explanation:

The line and dots are closed circle, so B and D would not be the answer.

The line have passed through the point (-6,4) and (0,2); we uses to find the slope.

slope = m = (y2 - y1)/(x2 - x1) = (2 - 4)/(0 - (-6)) = -2 / 6 = -1/3

we plug in slope to the linear equation in form of y = mx + b, where m is the slope, and b is the y- intercept.

y = -1/3x + 2

So the answer is A.

I can talking a flow proof about geometry 
A flow proof is just one representational style for the logical steps that go into proving a theoremor other proposition; rather than progress read in two columns, as traditional proofs do flow proofs utilize boxes and linking arrows to show the structure or the argument.

Betty and Dyan can pick 8 quarts of strawberries in 45 minutes if they work together. It takes Dyan x minutes to pick 8 quarts o
maks197457 [2]

Answer:

The answer is letter c.

Step-by-step explanation:

In order to know the answer, it is best to check what is given in the scenario above.

45 minutes = the time it takes for Betty and Dyan to pick 8 quarts of strawberries.

45x minutes= this refers to the time it takes for Dyan to pick 8 quarts of strawberries

In the rational expression, 45x-10, we've already known that 45x refers to minutes or the time it takes for Dyan to pick 8 quarts of strawberries, thus 10 here refers to minutes or time as well.

The mathematical operation used is<u> "subtraction,"</u> so this means that Betty takes a shorter time than Dyan when it comes to picking strawberries in the situation above.

Thus, the denominator represents the time it takes Betty to pick 8 quarts of strawberries if she takes 10 fewer minutes than Dyan.
