Answer:

See below.

Step-by-step explanation:

Formula: A = πr²

Since the radius is 4, we fill in the formula with the radius.

A = (3.14)4²

A = (3.14)16

A = 50.24

Answer:

36.5 sq cm

Step-by-step explanation:

If you find the length of AB then you know the diameter and can find the area.

3.9^2 + 5.6^2 = c^2

15.21 + 31.36 = c^2

46.57 = c^2

6.82 = AB

The radius is half of that, so it is 3.41. Radius squared x pi = area

36.5 sq cm

Answer:

36.576 cm²

Step-by-step explanation:

We can simply figure out the hypotenuse of the triangle which is the diameter of our circle, then use the radius to get the area of the circle:

[tex]a^2+b^2=c^2\\\\5.6^2+3.9^2=c^2\\\\31.26+15.21=c^2\\\\46.57=c^2\\\\c=\sqrt{46.57}[/tex]

Since we have our diameter, the radius is simply [tex]r=\frac{\sqrt{46.57}}{2}[/tex],  and finding the area of the circle becomes simple enough:

[tex]A=\pi r^2\\\\A=\pi(\frac{\sqrt{46.57}}{2})^2\\ \\A=\pi(\frac{46.57}{4})\\ \\A\approx36.576[/tex]

Therefore, the area of the circle is 36.576 cm²

If the mean time to respond to a stimulus is much higher than the median time to respond, the shape of the distribution of response times is positively skewed

For a distribution, the following are the relationships between the mean and the median values

When the mean is greater than the median, it means that the distribution is skewed right or positively skewed

Hence, the shape of the distribution of response times is positively skewed.

Answer:

first one is 42/7 = 6

11*6 = 66

second one

1/2 inch = 3/2 feet

17/2 inches = 17*3 = 51/2 = 25.5

Answer:

Question 4

You have actual length of the stage is 42 feet and the scale drawing is 11cm: 7ft. Divide the 42 by 7 and the answer is 6. You would need 6 of the 7 ft increments to equal the total of the 42 ft stage. If you multiply one side of a ratio, then you have to multiply both sides. 11 x 6= 66!

Step-by-step explanation:

42/7 = 6

11cm x 6: 7ft x 6

66cm: 42ft

Question 5

You have an actual length of the garage is 8 1/2 inches, or 8.5 inches on the blueprint. It take 2 of the 1/2 inch segments to get 1 inch. You need 8 1/2 or 8.5 total inches. You have to multiply 8.5 by 2 to get the total number of 1/2 inch increments that you need. 8.5 x 2 = 17. This tells you that you would need 17 of the 1/2 increments to get your total blueprint length. If you multiply one side of a ratio, then you have to multiply the other side. 17 x 1 1/2 or 1.5 = 25.5

Step-by-step explanation:

1/2 inch or 0.5 inch x 2 = 1 inch

8 1/2 inches or 8.5 inches x 2 increments = 17 increments

1 1/2 ft or 1.5 ft x 17 = 25.5 ft

$100

Step-by-step explanation:

if you are increasing your total amount by a percent, add 100 to the number and multiply. make sure you have your decimals in place.!!!

The groceries cost price on the next bill is $100.

The original price of the product is the cost price. The amount that a customer pays to buy a product is called the selling price.

For the following situation,

Initial spending amount on groceries = $80

Expensive percentage on next bill = 25% = 0.25

Groceries cost on next bill = [tex]80 + (80) ( 0.25)[/tex]

⇒ [tex]80+20[/tex]

⇒ [tex]100[/tex]

Hence we can conclude that the groceries cost price on the next bill is $100

Step-by-step explanation:

3/4x - 7 = -1

Your first step is to isolate the variable term 3/4x, to do this you have to add 7 to both sides:

3/4x -7 (+7) = -1 (+7)

3/4x = 6

Next, you want to get rid of the fraction by multiplying both sides by the denominator #, 4

3/4(x4) x = 6(x4)

3x = 24

Final step, you divide by three to isolate the x!

3x/3 = 24/3

x = 8

Hope this helps! =D

Step-by-step explanation:      

Step 1: Add 7 to both sides.

[tex]\frac{3}{4}x-7+7=-1+7[/tex]

Step 2: Simplify

[tex]\frac{3}{4}x=6[/tex]

Step 3:  Multiply both sides by 4

[tex]4\cdot \frac{3}{4}x=6\cdot \:4[/tex]

Step 4: Simplify

[tex]3x=24[/tex]

Step 5: Divide both sides by 3

[tex]\frac{3x}{3}=\frac{24}{3}[/tex]

Step 6: Simplify

[tex]x=8[/tex]

Explanation in words (Short Form)

-  The first step is to add 7 to both sides and the answer will result as 3/4x=6.

- The second step is to multiply both sides by 4/3 and the final answer will result as x = 8.

There are 32 conference games scheduled.

Since the little twelve football conference has two divisions, with nine teams in each division. each team plays each of the other teams in its own division twice once.

Since each team plays two matches against every other team, and plays against 8 teams, the number of games in each division is 2 games/team × 8 teams = 16 games.

Since there are the same number of teams in each division, so there are the same number of games per division and there are 2 divisions, the total number of games in the conference = games per division × number of divisions

= 16 games/division × 2 divisions

= 32 games.

So, there are 32 conference games scheduled.
