Answer:

[C] 25π square inches

Step-by-step explanation:

Given that:

the long hand of the clock is about 5 inches long.

To Find:

What is the approximate area of the clock face?

Solve:

Formula - A =πr²

Note that;

π = 3.14 (about)

Radius - 5 inches

A =πr²

A = 3.14(5)²

A = 3.14(25)

A = 78.5

Now let see the answer choices:

A.  5π square inches                     ≈   5(3.14) = 15.7

B. 10 π square inches                    ≈  10(3.14) = 31.4

C. 25 π square inches                    ≈  25(3.14) = 78.5

D. 100 π square inches                    ≈ 100(3.14) = 314

Hence, the answer is [C] 25 π square inches

your welcome

After the first pour the water remains 1/2, after the second 1/3, after the third is 1/4, and after 9 pour the water remains 1/10.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

After the first pour container has = 1/2

After the second pour = 1/3

Third pour = 1/4

After n pour = 1/(n+1)

n = 9

= 1/10

Thus, after the first pour the water remains 1/2, after the second 1/3, after the third is 1/4, and after 9 pour the water remains 1/10.

Answer:  A = 0.28

Step-by-step explanation:

By using the graph, all of the true statements that apply include the following:

B. The variables are dollars and hours.

C. Hours is the independent variable and dollars is the dependent variable.

F. The relationship is y = 3.50x.

In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be modeled or represented by the following mathematical equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) by using the various data points from table D as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 3.5/1 = 7/2 = 10.5/3

Constant of proportionality, k = 3.50

Therefore, the required linear function is given by;

y = kx

y = 3.50x

Answer:

Area = 13

Step-by-step explanation:

see image. There's a brick of 8 whole squares on the bottom. Then a layer of 3 whole squares on top of that. There's a 1/2 a square besides the 3. Then on top, there is half of a layer of 3 squares. Half of 3 is 1 1/2.

8 + 3 + 1/2 + 1 1/2

= 8 + 3 + 2

= 13

The days she has recorded: 11 + 10 + 7 + 6 + 3 + 2 = 39
The mode distance (most often): 5 km
Median distance: 6.64 km ~= 6.5 km ~= 7 km by rounding upwards, so 3rd

Cumulative frequency: 11; 21; 28; 34; 37; 39

Answer:

The answer is [tex]\frac{4}{8}[/tex] (see the attached picture)

Step-by-step explanation:

the distance between 0 & 1 is divided into 8 sections, meaning each section = [tex]\frac{(1-0)}{8} =\frac{1}{8}[/tex]

It is given that Joe was being exposed to an electromagnet shrinking machine. Because of this his height started decreasing .

Given,

The decrease was at a constant rate per second.

In 1.5sec, the height is decreased by 120cm.

So,

Variation per second =

Change in each second would be with negative sign indicate's decrease .

Hence, Answer is “-80” .

Equivalent expressions: negative numbers & distribution

Step-by-step explanation:

Answer:

5.  s ÷ 10, 8b, h + 7, 3r - 8

6. 248

Step-by-step explanation:

5.s divided by 10 would be written as s ÷ 10. 8 times b would be written 8b or 8 x b. 7 more than h would be written h + 7 because you are doing 7 more that h not h more than 7. 8 less than the product of 3 and r is written 3r -8 because the word product means to multiply. So, the question is 8 less than 3 times r which is written 3r -8 or (3 x r) - 8.

6. is 248 because if you drive 62 miles each hour and you drive for four hours you will go 248 miles in total. You just multiply 62 times 4.

Answer:

G

Step-by-step explanation:

The decimal value (to the nearest hundredth) of √6 is : 2.49

Hence, the point which lies roughly in the middle of 2 and 3 is : G

Answer:

G

Step-by-step explanation:

to identify which number √6 is closest too, we should look at the perfect squares closest to 6

the two closest perfect squares would be 4 and 9

√4 = 2 and √9 = 3

6 is about in between 4 and 9

so we can expect √6 to be in between 2 and 3 more in the middle so G is the best answer

Answer:

We are given a perimeter and three different lengths and we need to determine the corresponding width and area.  

The first length that is provided is 2 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(2 + 6) which gives us a perimeter of 16 feet and a width of 6 feet.  We can then get the area by multiplying the length by width which gives us 12 feet squared.

The second length that is given is 4 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(4 + 4) which gives us a perimeter of 16 feet and a width of 4 feet.  We can then get the area by multiplying the length by width which gives us 16 feet squared.

The final length that is given is 5 feet and to get a perimeter of 16 feet which we can then use the perimeter formula to get 2(5 + 3) which gives us a perimeter of 16 feet and a width of 3 feet.  We can then get the area by multiplying the length by width which gives us 15 feet squared.

Therefore, the field that would require the most amount of paint (the largest area) is option B, region #2.

Answer:

The last test score should be 73

Step-by-step explanation:

[tex]88 = \frac{( 87 + 94 + 86 + 100 + X )}{5}[/tex]  

Add all the values in the parentheses together to get:

[tex]88 = \frac{367 + X}{5}[/tex]

You want to remove the 5 next, so you multiply both sides by 5.

[tex]5 * 88 = \frac{367 + x}{5} *5[/tex]

[tex]88 * 5 = 440[/tex]

You should get:

[tex]440 = 367 + x[/tex]

The last step is to subtract both sides by 367:

[tex]440 - 367 = 73[/tex]

[tex]X = 73[/tex]

I hope this helps!

Answer:

a) 156.25 cm^2  b) 221.67 cm^2  c) 65.42 cm^2

Step-by-step explanation:

a)

We know that the formula for the area of a quadrilateral is Length x Height (A = LH).

Since the length and height of a square is the same, L = 12.5cm and H = 12.5cm.

So we incorporate our formula for the area of a square into this situation:

A = 12.5 x 12.5

A = 156.25 cm^2

b)

We know that the formula for the area of a circle is Pi x radius squared (A = πr^2).

Since we know that the diameter of the circle is 16.8cm, we will use this to find the radius.

Radius can be found by halving the diameter (r = d/2).

So we incorporate our formula for radius into this situation:

r = 16.8/2

r = 8.4cm

Now that we have our radius, we can find the area of our circle.

So we incorporate our formula for the area of a circle into this situation:

A = π(8.4)^2

A = 221.6707776 = 221.67 cm^2

c)

We can see from the diagram that the shaded portion come mainly from the circle.  So to find the area of the shaded part, we can simply subtract the area of the square, from the area of the circle (A of circle - A of square = Area of shaded part).

So we incorporate our formula for the area of the shaded part into this situation:

A = 221.67 cm^2 - 156.25 cm^2

A = 65.42 cm^2

Answer: She went [tex]11[/tex] times during the summer.

Step-by-step explanation:

If Louisa's savings change by [tex]-6[/tex] each time she goes bowling and it went to [tex]-66[/tex], that means that Louisa went another [tex]11[/tex] times.

[tex]\frac{1}{11}[/tex]

So therefore your answer would be 11.
