A 20-inch bicycle has tires with a diameter of 20 inches. What is the circumference of these tires?
31.4 inches
62.8 inches
314 inches
1256 inches
Answers
Answer:B
Step-by-step explanation:
c=2nr or c=nd
2*3.14 * 10= 62.8
3.14 * 20= 62.8
The circumference of the tires is 62.8 inches.
What is Circumference?Circumference of a circle is defined for non straight curves which is the length of the boundary of the curve.
Given that, a 20-inch bicycle has tires with a diameter of 20 inches.
Diameter of the tire = 20 inches.
Radius of a circle or a circular object is half of the diameter of it.
Radius of the tire = 20 / 2 = 10 inches
Circumference of a circular object = 2πr, r is the radius.
Circumference of the tire = 2π r
= 2 (3.14) (10)
= 62.8 inches
Hence the circumference of a bicycle tire is 62.8 inches.

priya finds (1.05) x (2.8) by calculating 105 x 28 then moving the decimal point three spaces to the left
Answers
Answer:
Yes, That is correct.
Step-by-step explanation:
Example: Multiply 0.05 by 1.1
start with:
0.05 × 1.1
multiply without decimal points:
5 × 11 = 55
0.05 has 2 decimal places,
and 1.1 has 1 decimal place,
so the answer has 3 decimal places:
0.055
Priya's method easy finds the product of decimals because multiplying whole numbers is easier than multiplying decimal numbers.
Given that, Priya finds (1.05) × (2.8) by calculating 105 × 28 and then moving the decimal point three spaces to the left.
We need to explain why Priya's method makes sense.
How to multiply two decimals?To multiply decimals, first, multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.
Now, 105 × 28 = 2,940
Moving the decimal point three spaces to the left, we get 2.940.
Also, (1.05) × (2.8) =2.940
Therefore, Priya's method easy finds the product of decimals, because multiplying whole numbers is easier than multiplying decimal numbers.

As seen from the graph attached in answer area as well, The graph is above x-axis (i.e. y value of equation) only when x has values {0, 1, 2, 3, 4}.
At x = 0:

At x = 1:
[tex]y = -|0-1| + 2 \\\Rightarrow -1 + 2\\ \Rightarrow y = 1[/tex]
At x = 2:
[tex]y = -|2-2| + 2 \\\Rightarrow 0 + 2\\ \Rightarrow y = 2[/tex]
At x = 3:
[tex]y = -|3-2| + 2 \\\Rightarrow -1 + 2\\ \Rightarrow y = 1[/tex]
At x = 4:

An alloy is composed of nickel, zinc, and copper in a ratio of 7:2:9. How many kilograms of each metal are needed to make 3.6 kg of this alloy?
Answers
Answer:
Nickel= 1.8 kg
Zinc= 0.4 kg
Copper= 1.8 kg
Step-by-step explanation:
7:2:9
7=nickel
2=zinc
9=copper
7+2+9=18
18×2=36
7×2=14 2×2=4 9×2=18
Divide by 10
14÷10=1.4 4÷10=0.4 18÷10=1.8
1.8+1.4+0.4= 3.6
1.8=nickel
0.4=zinc
1.8=copper
Amount of each metal are needed to make 3.6 kg of this alloy are,
Nickel = 1.4 kg
Zinc = 0.4 kg
Copper = 1.8 kg
We have to given that,
An alloy is composed of nickel, zinc, and copper in a ratio of 7 : 2 : 9.
Now, We can assume that,
Amount of nickel = 7x
Amount of zinc = 2x
Amount of copper = 9x
Hence, We get;
⇒ 7x + 2x + 9x = 3.6
⇒ 18x = 3.6
⇒ x = 3.6 / 18
⇒ x = 0.2
Thus, WE get;
Amount of nickel = 7x
= 7 × 0.2
= 1.4 kg
Amount of zinc = 2x
= 2 × 0.2
= 0.4 kg
Amount of copper = 9x
= 9 × 0.2
= 1.8 kg

Twenty people apply for an open position at an accountant's office. The distribution of ages of the applicants is shown in the box plot.
Distribution of Applicant's Ages
How many of
age in years
the applicants have ages that fall within the box of the box plot?
Please help!!!!
Answers
Answer:
The number of applicants that have ages that fall within the box of the boxplot = 10.
Step-by-step explanation:
box plot is constructed from five values: the minimum value, the first quartile, the median, the third quartile, and the maximum value.
The boxplot usually consists of a box and a whisker plot.
The whiskers represent data that is less than the first quartile or 25th percentile and data that is more than the third quartile or 75th percentile.
The box of the boxplot is bounded by the first quartile or 25th percentile and the third quartile or 75th percentile.
Hence, the fraction of the distribution that is usually contained in the box of the boxplot is (75 - 25), 50% of the distribution.
The total number of applicants = 20
50% of 20 = 10.
Hence, the number of applicants that have ages that fall within the box of the boxplot = 10
