The scale factor is: 2x

This is because if you take MN and see that it went from 4 sq to 8 sq. And we then take LM and see that it went from 6 sq to 12 sq. We can now see that it was a full 2x dilation.

Answer:

Step-by-step explanation:

The scale factor is 1/2.  The dimensions given for the smaller rectangle are 1/2 those of the larger rectangle.

Answer:

because it easily displays all of the info

Here's what we know:

4t = 7/10 (4 tasks take 7/10 of an hour)

Divide both sides by 4:

4t / 4 = 7/10 / 4

t = 7/40

So each task is 7/40 of an hour

7/40 n = 1 (Now we want to find the number of tasks completed in 1 hour)

Multiply both sides by 40/7:

n = 40/7

Converting improper fraction to a mixed number:

n = 5 5/7

So the robot will complete 5 5/7 tasks in an hour. If the answer is looking for fully finished tasks and not partially done ones, the you need to round down to 5.

We know that a robot can complete 4 tasks in [tex]\frac{5}{6}[/tex] hour. Each task takes the same amount of time

We need to know how long it takes the robot to complete one​ task

[tex]\frac{5}{6}[/tex] of an hour is also equal to 50 minutes.

So now, we divide:

50 ÷ 4 = 12.5

One thing we can do to check our work is to multiply:

12.5 x 4 = 50

it takes the robot 12.5 minutes to complete one​ task

We know that a robot can complete 4 tasks in [tex]\frac{5}{6}[/tex] hour. Each task takes the same amount of time

We need to know how many tasks the robot complete in one​ hour.

Using the information from Part A, we know that [tex]\frac{5}{6}[/tex] is 50 minutes. We also know it take the robot 12.5 minutes to complete one task. 60 minutes is equal to one hour. So what we would do is divide:

60 ÷ 12.5 = 4.80

The robot cannot complete 5 tasks in one hour.

To check our work, we can multiply:

4.80 x 12.50 = 60 or one hour

The robot can complete 4.8 tasks in one hour.

Answer:

The area of this triangle is 72 cm².

Step-by-step explanation:

We know all 3 lengths of this triangle (12, 12, 17), but all we need to answer this question is sides a and b (12, and 12).

The formula to find the area of a triangle is A = bh/2. Substitute b and h for 12 and 12 respectively.

A = (12 * 12)/2

A = 144/2

A = 72 cm²

The area of the triangle is 72 cm².

Solve for the first variable in one of the equations, then subsitute the result into the other equation.

Answer:

what grade?

Step-by-step explanation:

The shape of the sampling distribution of the proportions of consumers will be skewed to the left. Hence, option A is correct.

Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.

As per the given information in the question,

Proportion = 92% = 0.92

Sample size, n = 100

As,

np = (100)(0.92) = 92

Use the equation given below,

n(1 - p)

= 100(1 - 0.92)

= 100 - 92

= 8

n(1 - p) = r < 10

When sampling distribution have fewer than 10 expected failure per sample, distribution of sample is left skewed.

Answer:

volume of cone is 1÷3πr×r h

Step-by-step explanation:

when we put value in this formula then 1÷3×22÷7×6×6×6 then answer will 72πm×m×m hence it will option B

The volume of a cone diameter of 12 m and a height of 6m is 72π cubics meter. So, option B is correct.

The volume of the cone is the product of one-third of the height, pie, and square of the radius.

The volume of the cone = 1/3πr^2 h

We need to find the volume of a cone diameter of 12 m and a height of 6m.

r = 6m

h = 6m

The volume of the cone = 1/3πr^2 h

                                       = 1/3×π×6×6×6

                                        =   72π

Thus, the volume of a cone diameter of 12 m and a height of 6m is 72π cubics meter.

Answer: The original price is $70.00

Step-by-step explanation:

The problem states that $59.50 is the discounted price, this means that it is not the 100% price of the aquarium. Since 15% is the discount, the remaining price is equivalent to 85% of the original price, which amount to $59.50.

100% - 15% = 85%

100% - 15% = $59.50

To get original price, we must divide the discounted price by its corresponding percentage.

$59.50 / 85% = original price

$59.50 / 0.85 = $70

To check, we must get the 15% equivalent amount from the original price.

$70 x 15% = $10.50 discount value

$70 - $10.50 = $59.50 discounted price
