Answer:

12 miles

Step-by-step explanation:

3 miles per 30 minutes

2 hours is made of 4 30 minutes, so 3 x 4 = 12

Answer:

The answer is 12 miles

Step-by-step explanation:

30 minutes is half an hour.

If 30 minutes is half an hour then, 2 hours is 120 minutes.

3 miles in this problem is 30 minutes, so 120 divided by 30 is 4 and 4x3 is 12.

There are no solutions to this question.

Step-by-step explanation:

Answer:

0=6       so there is no solution

Step-by-step explanation:

4(x+3)=2(2x+9)

expand the brackets

4x+12=4x+18

-12 on both sides

4x=4x+6

-4x on both sides

0=6

Answer:

2 meters

Step-by-step explanation:

I really don't know if this is right. It is just a guess:

8-6=2 so the windowsill is 2 meters off the ground because if the ladder is leaning 6 meters out, you have to take 6 meters away from 8, which leaves you with 2 meters.

Answer:

$2.40

Step-by-step explanation:

We know that the sales tax is 8% , we also know that we want to buy two t shirts that cost $15.00 each.

So first, look at what we are purchasing, two t-shirts costing 15.00 dollars each.

Since we are buying two, multiply $15 by 2,

==> $30.00 dollars

And since the sales tax is 8%, to find how much we will pay will mean to multiply the amount by the percent,

30 * 8%

==> $2.40 dollars

You will pay $2.40 dollars in tax

Answer:

the length of the pond is 10 feet.

Step-by-step explanation:

The computation of the length of the pond side is shown below:

Let us assume the length of the pond side be x feet

Now the one side length with the brick border is x + 4

And, the pond is 196 square feet

Now the equation would be

(x + 4)^2 = 196

(x+4) = 14

x = 10

Therefore, the length of the pond is 10 feet.

The length of each side of the pond is required.

The length of the side of the pond is 10 feet.

Let [tex]x[/tex] be the length of each side of the pool.

If the brick layer is 2 foot wide the size then 2 foot would be added to all the sides of the pool.

The length of each side would be [tex]x+2+2=x+4[/tex]

The area of the pool is [tex]196[/tex] square feet.

So,

[tex](x+4)^2=196\\\Rightarrow x+4=\sqrt{196}\\\Rightarrow x+4=\pm14\\\Rightarrow x=10,-18[/tex]

Since, negative number cannot be the length.

[tex]x=10\ \text{feet}[/tex]

Answer:

1. ▲ABC ~ ▲A'B'C' because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/3 and then rotating it about the origin by 180 degrees.

Step-by-step explanation:

given;

ABC / A= (-12, 12) / B= (-9, 6) / C= (-3, 12)

A'B'C' / A'= (4, -4) / B'= (3, -2) / C'= (1, -4)

consider line AC = 9

                      A'C' = 3

ratio is 9/3, so the factor is 1/3

(78, 80)

Step-by-step explanation:

Given a normal distribution :

Mean = 79 seconds

Standard deviation = 0.5 seconds

Using the empirical rule :

95% of her finishing times :

According to the empirical rule, 95% represents 2 standard deviations from the mean that is ± 2 standard deviations from the mean score or value.

Hence ;

The interval will be defined as ;

Mean ± 2(standard deviation)

79 ± 2(0.5)

79 ± 1

(79 - 1) ; (79 + 1)

78 ; 80

Answer:

$28.80

Step-by-step explanation:

Multiply $24 by 20% (0.20)

24 x 0.2 = 4.80

So, the tip is $4.80

Add the tip to the price of the tab

24 + 4.8 = 28.8

So the overall price of the restaurant tab is $28.80

In repeated sampling from the distribution of S , the average of the values will approach 4.66.

Step-by-step explanation:

The correct interpretation of the mean is in repeated sampling from the distribution of S, the average of the values will approach 4.66.

The Geometric distribution is a discrete probability distribution that shows the likelihood of the number of failures before the success attained.

Let consider S to be a random variable that represents the selected adults in a community surveyed.

Then

[tex]\mathbf{S \sim G(p) S = 4.66}[/tex]

Therefore, the correct interpretation of the mean is in repeated sampling from the distribution of S, the average of the values will approach 4.66.

Step-by-step explanation:

Answer:

1. -21

2. 46

3. 2

4. -4

5. 10

6. -10

Step-by-step explanation:

1. gh = (-7)(3) = -21

2. g² - h = (-7)² - (3) = 49 - 3 = 46

3. g + h² = (-7) + (3)² = -7 + 9 = 2

4. g + h = (-7) + (3) = -4

5. h - g= (3) - (-7) = 10

6. g - h = (-7) - (3) = -10
