How do you estimate decimals?

Answers

Answer 1

Answer: If you are rounding to the nearest tenth
Let's say round 20.15 to the nearest tenth. 1 is the tenth place. You have to look at the hundredths place. Since it is 5 and over You round up. If it is under 4 then you round down to it would be 20.2

Answer 2

Answer: 1. Find the place value you want (the "rounding digit") and look at the digit just to the right of it.
2. If that digit is less than 5, do not change the rounding digit but drop all digits to the right of it.
3. If that digit is greater than or equal to 5, add one to the rounding digit and drop all digits to the right of it.

Hope this helps!!!!!!

Answer

You will pay $0.20 (20 cents) more on a $20 purchase.

Explanation

To find a percentage of any number we just need to multiply the number by the percentage and divide by 100

First, we'll find the 7% of $20:

$(7*20)/(100) =(140)/(100) =1.40$

Next, we'll find the 8% of $20:

$(8*20)/(100) =(160)/(100) =1.60$

Finally, we just need to subtract $1.40 form $1.60:

$Tax Increment=1.60-1.40=0.20$

We can conclude that after the increasing of sales tax from 7% to 8%, you will pay $0.20 (20 cents) more on a $20 purchase.

which equation is represented by the function table below? x's are 1,2,3,4 y's are 8,14,20,26

Answers

f: R -> R, f(x) = ax + b;
f(1) = 8 => a + b = 8;
f(2) = 14 => 2a + b = 14 => a = 6 and b =2;
f(3) = 20 => 6*3 + 2 = 20 True;
f(4) = 26 => 4*6 + 2 = 26 True;

then, f:R -> R, f(x) = 6x + 2;

$\int\limits{(x)} = 6x + 2$

One thousand and twenty students participated in the school math contest. Sample 1 is a random sample from grades 9 and 10 and consists of the following scores: 72, 89, 67, 81, 75, 79, 81, 80, 62, 64, 83.

Sample 2 is a random sample from grades 11 and 12 and consists of the following scores: 84, 86, 87, 84, 86, 89, 90, 87, 87, 84, 86.

Choose the following statements that correctly compare the two samples.
Check all that are true.

A). Sample 2 shows 11th and 12th grade students, on average, did better.

B) . Sample 1 has a higher probability than Sample 2.

C). The measure of center is the same for both samples.

D). Sample 1 shows 9th and 10th grade students, on average, did better.

E). Sample 2 has a higher median score than Sample 1.

Answers

Answer:

E)- Sample 2 has a higher median score than Sample 1.

Step-by-step explanation:

For comparing both samples by the median, We are more clear that Sample 2 (grades of 11th and 12th) is better than Sample 1 (grades of 9th and 10th).

We didn't choose other options because neither only seeing the samples nor by measuring the probability of both samples We do a better comparison of both the samples.

Also by measuring the mean and median of the both given samples we get both Option C and D are incorrect.

With the way its set up I would have to say the answer id E. due to the fact that the average, or median is higher in sample 2.

A box contains 100 colored chips; some are pink and some are blue. Milton chooses a chip at random, records the color, and places it back in the bag. Milton has recorded 12 pink chips and 18 blue chips. Using these results, what is the predicted number of pink chips in the box?

Answers

So milton picked up 30 chips and of these 12 were pink. 12/30 were pink. To make 30 to 100 we multiply by 3.3333. We must also multiply the top number of the fraction as well. So 12*3.333=40 and 30*3.333=100. So you can estimate that the total number of pink chips in the box is 40

The volumes of each figure that make the composite figure have been determined.Cone V = 24π cm3

Cylinder V = 63π cm3

How is the volume of the composite figure calculated?
-add the 2 volumes
-divide the 2 volumes
-multiply the 2 volumes
-subtract the 2 volumes

What is the approximate volume of the composite figure? Round to the nearest hundredth.
8.25 cubic centimeters
122.52 cubic centimeters

Carla is wrapping a present in the box shown. How much wrapping paper does she need, not including overlap? *it is a rectangular prism: 4in (height) 3in (width) 10in (length)

Answers

Answer:

Carla needed 164 inches² wrapping paper to wrap the present.

Step-by-step explanation:

Given : A rectangular prism having length 10 inch , width 3 inch and height 4 inch.

We have to find the length of wrapping paper does Carla need to wrap the present which is in form of given rectangular prism (not including overlap)

The length of wrapping paper needed will be equal to the total surface area of rectangular prism.

total surface area of rectangular prism = 2( lw +wh + hl)

Where l denotes length , w denotes width and h denotes height

Given length = 10 inch ,

width = 3 inch

height = 4 inch.

Substitute, we get,

total surface area of rectangular prism =2 (10× 3 + 3× 4 + 4 × 10 )

total surface area of rectangular prism =2 (30 + 12 + 40)

Total surface area of rectangular prism = 164 inches²

Thus, Carla needed 164 inches² wrapping paper to wrap the present.

2(area of s) + 2(area of f) + 2(area of ff) if s = side and f= opposite faces and ff = opposite faces.
2(4x3) + 2(3x10) + 2(4x10)=
24+60+80=
164 in squared
