Find the circumference of the circle that has a radius measurement of 11 1/4
Answer:
22.5π units² or about 70.65 units²
Step-by-step explanation:
11 [tex]\frac{1}{4}[/tex] is equivalent to 11.25
The formula for the circumference of a circle is 2πr. Using that formula we get:
2*π*11.25 = 22.5π ≈ 70.65
Answer:
70.69 or 22.5 pi
Step-by-step explanation:
To find the circumference of a circle, you can use the formula:
2 x pi x radius
Using this formula, we can substitute the information that we already know, and solve for the circumference:
2 x pi x 45/4
6.28 x 45/4
70.69 or 22.5 pi

b) 10/35 of the participants who preferred B are girls.
c) The ratio of boys who preferred C is equal to the ratio of girls who preferred C.
d) 20/35 of the boys preferred D.
Answer:

Answer:
(C) The ratio of boys who preferred C is equal to the ratio of girls who preferred C
Step-by-step explanation:
A is incorrect because the ratio of girls to boys in the survey is 120/80 which is 60%
B is incorrect because the ratio of girls who prefrerred B to the ratio of boys is 10/25 not 10/35
D is incorrect because once again 20/15 does not equal 20/35
C is the correct answer and the only correct answer despite the multiple choice question because the ratio of boys that preferred c to girls is the exact same
What are all the simplified form of the equation 3(4x - 2) = 9 + 2x + 5
Step-by-step explanation:
Step 1: Distribute
[tex]3(4x - 2) = 9 + 2x + 5[/tex]
[tex](3 * 4x) + (3 * -2) = 14 + 2x[/tex]
[tex]12x - 6 = 14 + 2x[/tex]
Step 2: Add 6 to both sides
[tex]12x - 6 + 6 = 14 + 6 + 2x[/tex]
[tex]12x = 20 + 2x[/tex]
Step 3: Subtract 2x from both sides
[tex]12x - 2x = 20 + 2x - 2x[/tex]
[tex]10x = 20[/tex]
Step 4: Divide both sides by 10
[tex]10x / 10 = 20 / 10[/tex]
[tex]x = 2[/tex]
Answer: [tex]x = 2[/tex]

A clothing company has 4 different kinds of sweatshirts. Each year, the company makes 60,000 of each kind of sweatshirt. How many sweatshirts does the company make each year?
Answer:
Step-by-step explanation:
Given that,
The company makes 4 different sweat shirts
Each year they make 60,000 of each kind.
So, if they will make 60,000 sweat shirt for each brand and the company design 4 different brand.
So, number of brand is 4
n = 4.
Then,
1 brand = 60,000
Therefore, 4 brand = 60,000 × 4
4brand = 240,000 sweat shirts.
So, in a year the company will make 240,000 sweat shirts.
The company makes a total of 240,000 sweatshirts each year by producing 60,000 of each of the 4 different kinds.
The question asks for the total number of sweatshirts produced by a company each year if it makes 60,000 of each kind and there are 4 different kinds of sweatshirts.
Identify the number of different kinds of sweatshirts: 4.Determine the number of each kind of sweatshirt made annually: 60,000.Multiply the number of kinds by the number of each kind: 4 x 60,000 = 240,000.Therefore, the company makes a total of 240,000 sweatshirts each year.
A pack of 6 cans of pop costs £1.80. A pack of 10 cans of pop costs £3.50.
Which one should you buy?
Let us look at the cost per can of both packs.
Cost of can in 6-pack = 1.80/6
= £0.30
Cost of can in 10-pack = 3.50/10
= £0.35
Since the cost of a can in the 6-pack is cheaper, it would be better to buy the 6-pack if you were looking to save money.

You are going on a field trip in a school bus. A special detector placed on one of the bus's tires counts the number of rotations completed by the tire during the journey. The tire's diameter is 1 meter, and it made 8000 rotations during the trip.
How far did the bus travel?
Answer:
25,133 m or 25.1 km
Step-by-step explanation:
The circumference of the tire is ...
C = πd
C = π(1 m)
The distance the bus traveled is 8000 times this far, so is ...
distance = (8000)(π m) = 8000π m
Using 3.14159 for π, we find the distance to be about
distance = (8000)(3.14159) m ≈ 25,133 m
The bus traveled about 25,133 meters or 25.1 km.
Answer:
25,133 m or 25.1 km
Step-by-step explanation:
The circumference of the tire is ...
C = πd
C = π(1 m)
The distance the bus traveled is 8000 times this far, so is ...
distance = (8000)(π m) = 8000π m

Find the circumference and area of a circle whose radius is 12.4 cm.Give your answer to the nearest centimeter (whole #). Circumference = cm Area = cm2
Final answer:
The circumference of the circle is approximately 78 cm and the area of the circle is approximately 484 cm².
Explanation:
The circumference of a circle can be found by using the formula:
Circumference = 2πr, where r is the radius of the circle.
Given that the radius is 12.4 cm, we can substitute this value into the formula:
Circumference = 2π(12.4 cm)
Using an approximation of π as 3.14, the calculation becomes:
Circumference = 2(3.14)(12.4 cm) = 77.9 cm
Therefore, the circumference of the circle is approximately 78 cm (to the nearest whole number).
The area of a circle can be found by using the formula:
Area = πr²
Substituting the given radius into the formula:
Area = 3.14(12.4 cm)² = 483.864 cm²
Therefore, the area of the circle is approximately 484 cm² (to the nearest whole number).

since 2010 the town of fall river has been experiencing a growth in population according to the model what will the population of fall river be in 2020
Answer:
the population of fall river will be 48558
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Since 2010, the town of Fall River has been experiencing a growth in population. The relationship between the elapsed time, t, in years, since 2010 and the town's population, P(t left parenthesis, t, right parenthesis, is modeled by the following function. P(t)=36,800⋅[tex]2^{\frac{t}{25} }[/tex] According to the model, what will the population of Fall River be in 2020? Round your answer, if necessary, to the nearest whole number.
My answer:
Given the exponential function:
P(t)=36,800⋅[tex]2^{\frac{t}{25} }[/tex] where:
t in years, since 2010 the town's population, P(t)As we know, from 2010 to 2010 are 10 years
Hence, to find the population of fall river be in 2020, we substitute t =10 into the given function:
[tex]P(10)=36800\cdot2^{^\dfrac{10}{25}}}\\=48557.9\\\approx 48558[/tex]
So in 2020, the population of fall river will be 48558
Hope it will find you well.
Answer:
By 2020 the population of Fall River will be 48558
Step-by-step explanation:
Here, we note that the equation for the model is p(t) = 36,800×2^(t/25)
That is the format;
[tex]p(t) = 36,800 \times 2^{\frac{t}{25}[/tex]
Where:
t = Number of years since 2010
Therefore, the population of the town in 2020 can be found by first finding the number of years between 220 and 2010 and plugging the value into the equation as follows;
Number of years, t = 2020 - 2010 = 10 years
Hence;
[tex]p(t) = 36,800 \times 2^{\frac{10}{25}} = 48557.89 \approx 48558[/tex]
Therefore, according to the model, by 2020 the population of Fall River will be 48558.
A baking pantry is making packages. Each package contains 4 identical bags of flour and a 7 pound bag of sugar. The package weighs a total of 64 pounds. How much does each bag of flour way
Answer:
The answer is 14.25 pounds.
Step-by-step explanation:
If the package contains 4 bags of flour and a 7 pound bag of sugar which weighs 64 pounds in total;
The total weight of the flour bags is 64 - 7 = 57 pounds.Since the flour bags are identical, they weigh the same. If we divide 57 by 4, we can find that the weight of each bag of flour is 57 / 4 = 14.25 pounds.I hope this answer helps.

Answer:
84 meters.
Step-by-step explanation:
Set each tower equal to each other and you get (3.1/1.71)=(x/46.5)
Solve for X
X≈84.2982
But we want the nearest meter, so it's just 84 meters.
Answer:
84 meters
Step-by-step explanation:
The proportional value, or ratio is as the following:
[tex]\frac{3.1}{1.71} = \frac{x}{46.5}[/tex]
Now we can cross multiply in order to solve the equation...
[tex]1.71x=3.1*46.5\\1.71x = 144 \frac{3}{20}\\ x=84.3[/tex]
Rounded to the nearest meter, x is 84 meters.
