4. Estimate the sum of 9.327 + 5.72 + 4.132 to one decimal place.18.729

Answers

Answer 1

Answer:

Answer:

Hence, the estimate value of 9.327 + 5.72 + 4.132 to one decimal place is:

19.2

Step-by-step explanation:

We have to Estimate the sum of 9.327 + 5.72 + 4.132 to one decimal place

We find the sum of these numbers:

Sum= 9.327+5.72+4.132

= 19.179

Now we have to estimate the value to one decimal place

so, on approximating the value, we get the sum=19.2

Hence, the estimate value of 9.327 + 5.72 + 4.132 to one decimal place is:

19.2

Answer 2

Answer: The sum for those numbers is 19.179 NOT 18.729. HOWEVER the Estimation of the sum and the answer for this question is 19.2 because the decimal place you are finding has a number to its right that is greater to that decimal place so you add the one to the decimal place you are finding.

What is 2x116 and 4x17

Answers

2* 116
= 2*(100+16)
= 2*100+ 2*16 ( distributive property)
= 200+ 32
= 232

The final answer is 232~

4*17
= 4*(10+7)
= 4*10+ 4*7 (distributive property)
= 40+ 28
= 68

The final answer is 68~

For 2times116 =232 and for 17times4=68

Answer the following questions about the problem above. Write in complete sentences to get full credit. 1. What is the slope for section "d" of Mrs. Washington's commute.
2. What does it mean that the slope is negative in context of the problem?
3. Why are the slopes different over different intervals?
4. How long does it take Mrs. Washington to get home? How did you know this?

Answers

Note: Since you missed to add the image, so after a little research, I was able to find the image related to this question, which hopefully serves the purpose to clear your concept. The image is attached below.

Step-by-step explanation:

Part 1) What is the slope for section "d" of Mrs. Washington's commute

Calculating the slope for section "d" of Mrs. Washington's commute:

Slope of the section d $=(y_(2) - y_(1))/(x_(2) - x_(1))$

$(6 - 0)/(32 - 20)=(1)/(2)=0.5$

Part 2) What does it mean that the slope is negative in context of the problem?

The slope is being negative as it is moving downward from the left. In negative slop, the value of x increase, while the vale of y decreases. In positive slop, the value of both x and y increases.

Part 3) Why are the slopes different over different intervals?

Slopes are different at different intervals as the distance covered in time taken for each part of the given journey are different, also the speed is not the same for each interval.

As the speed can be calculated as

$Speed\:=\:(distance)/(time)\:$

Distance = $y_(2) -y_(1)$ = $20 - 15 = 5$

Time = $x_(2) -x_(1)$ = $8 - 0 = 8$

Speed = $(5)/(8)=0.625$

Therefore, the speed in the part 1 is $0.625$ $ms^(-1)$

Part 4) How long does it take Mrs. Washington to get home? How did you know this?

It is clear from the graph that does take 32 minutes to her to get home.

We can observe it from the graph that it represents the total time taken across the entire journey.

It seems like you didn't provide the specific values for the difference of the numbers, so I cannot calculate the two numbers without that information. If you can provide the difference of the numbers or any additional information, I'd be happy to help you find the two numbers.

1. Discuss the differences between the measurement of the surface area and the measurement of the volume of a right rectangular prism. Include the following topics in your discussion:• Description of regions that are measured
• Units for each type of measure and why the units are different
• Examples of when you would want to measure for each type of measure.

Answers

Surface area define or calculate the exact space that each face of the said shape is taken up while the volume is how much space is inside the said object. The area use the unit that is squared because it only measured 2 face in the shape while the volume measures 3 faces in the object. an example of an area is a card board area, while the volume is the glass of water.

Which expression is irrational? 8 over 5. square root of 4 square root of 10. square root of 64

Answers

The expression which is irrational is √10. Also, 8/5 is rational. √4 is rational. √64 is rational.

What are rational numbers and irrational numbers?

Rational numbers are numbers that can be written in the form of $(a)/(b)$ where a and b are integers.

Example: 1/2, 3.5 (which is writable as 7/5), etc.

Irrational numbers are those real numbers that are not rational numbers.

Know that all natural numbers are integers, and all integers are rational numbers. That means natural numbers are not irrational.

8/5 is rational. It is expressed in the form of $(a)/(b)$ .

√4 = 2 = 2/1 . This is rational because it is expressed as the ratio of two integers.

√64 = 8. This is rational because it is expressed as the ratio of two integers.

√10 = 3.16227..... The decimal part does not end and it is irrational because it can not be expressed in the form of $(a)/(b)$ .

Therefore √10 is irrational.
