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.

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

7. The distance between point (–4, 5) and another point is 10. What are the possible
coordinates of the other point?
A (2, 2)
B (2, 3)
C (2, –3)
D (–2, –3)
Answers
Answer:
D (-2, -3)
Step-by-step explanation: The distance is 10 units, so you take -4 (x) and go over 2 spaces so your at x = -2, and 2 units are down, 8 more to go. Then for (y) you do 5-8 and get -3 so now y = -3 . Now you have moved 10 spaces because 2 + 8 = 10 spaces, and are left at D (-2, -3).
The Distance Between -4 And 2 Is 6 (6^2=36)
The Distance Between 5 And -3 Is 8 (8^2=64)

What is a function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given that, a graph we need to find its function,
To analyze the given graph let us,
compare the given to a known, standard functiontake maxima and minima points from the graph and analyze them.From the given graph we can pick the points which can tell us about the nature of the cosine function we took,
It is clear from the graph that the function plotted is equal to the standard function i.e. cos(x)
in cos(x) ⇒ we have minima at (-π, 1)
in the given graph, the function has a maximum and touches the y-axis at (0, 0.5)
Therefore, 0.5cosx is the function represented in the graph.

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.
