Answer: The least common denominator is: 60
Then comparing 100/60 with 100/60

100/60 = 100/60,

Round 649,418 to the nearest ten,_____,nearest hundred_____,nearest thousand_____,nearest ten thousand_____,nearest hundred thousand______

Answers

The approximations of 649,418 are as follows;

Nearest ten = 649,420

Nearest hundred = 649,400

Nearest thousand = 649000

Nearest ten thousand = 650000

Nearest hundred thousand = 600000

This is about approximation of whole numbers.

When given whole numbers, the last number from the right is called units and the next is called tens followed by hundreds then thousands, then ten thousands, then hundred thousands e.t.c.

We are given the number 649,418; It means;

Units digit is 8

Tens digit is 1

Hundreds digit is 4

Thousands digit is 9

Ten thousands digit 4

Hundred thousands digit is 6

1) Approximating the nearest tenmeans if the units digit is 5 or more than 5, we add 1 to the tens digit. In this case, we will have; 649,420.

2) Approximating thenearest hundred means if the tens digit is 5 or more than 5, we add 1 to the hundreds digit otherwise we leave it and make every other term to its' right 0 to get; 649,400.

3) Approximating thenearest thousand means if the hundreds digit is 5 or more than 5, we add 1 to the thousands digit otherwise we leave it and make every other term to its's right 0 to get; 649,000.

4) Approximating thenearest ten thousand means if the thousands digit is 5 or more than 5, we add 1 to the ten thousand digit to get 650,000.

5) Approximating the nearest hundred thousandmeans if the ten thousand digit is 5 or more than 5, we add 1 to the hundred thousand digit otherwise we leave it and make every other term 0 to get 600,000.

A student solved this problem and said the answer is 5 pounds. Todd has two packages of hamburger. One package weighs 4/5 pound and the other weighs 9/10 pound. What is the total weight of both packages of hamburger combined?

Is the student's answer reasonable?

Answers

No, the students answer is decently far off the correct answer would be 1 7/10 pounds because, to add fractions you first need to find a common denominator that both of the numbers go into for example for this one 10 is a common denominator because 5 goes into 10 twice and 10 goes into 10 once so we multiply 4/5 by 2 because it take twice the amount of 5 to get to 10 and what we do to one side we must replicate on the other side as well. Like so,
4/5*2=8/10 now all the we have to do is take 8/10+9/10=17/10 and simplifying that down you get 1 7/10 because 10 goes into 17/10 one time with 7 left over and because 7 is prime that answer can not be simplified down any more.

Enjoy!=)

The answer is no, because the net weight or the pounds the packages weigh together isn't close to 5 pounds---------->

given
two packages of hamburgers
4/5 of a pound, package 1
9/10 of a pound, package 2
--------------------------------
10/10 =1pound
5X 10/10= 50/10= 5pounds
first convert both to same denominator, find the lowest common multiple between the denominators, 10,5
10 is the smallest so lets turn all answer into something over #/10
4 X
-- = --
5 10
  √
5x2=10
what ever you multiply the bottom you multiply to the top
we multiplied the bottom by 2 so we need to multiply the top by 2/ 4X2=8

--
10
-------------
since 9/10 already has 10 in the denominator we can keep this as this is
-----------------------------------------------------------------------------------
8 9 17   7 17   17 50
-- + --= --- = 1 -- =---pounds of hamburgers.   -- ≠5 pound/ --- pounds

A park ranger finds that 35% of the park's visitors stay at the campground. if 105 visitors stayed at the campground one day, how many visitors did the park have that day? can you please explain it too.

Answers

Answer:

The park had 300 visitors that day

Step-by-step explanation:

The park ranger finds that 35 percents of their visitors stay at the camp ground. This means if y numbers of visitors visits the park, it is likely 35% of y stayed at the campground.

According to the question, a particular day 105 visitors stayed at the camp ground. The visitors that stayed at the campground that day represent 35% of the visitors that visited the park.

Let us make the number of people that visited the park = y

35% of y can be computed below ;

35/100 × y = 105

35y/100 = 105

cross multiply

35y = 10500

y = 10500/35

y = 300

Marissa researched the cost to have custom T-shirts printed by several local and online vendors. She found that each store’s charge for the job could be modeled by a linear function that combined a flat charge for artwork with a per T-shirt rate. Marissa plotted the functions on a coordinate grid and found that two of the functions produced lines that had the same y-intercept. How should Marissa interpret this result?A.Those two vendors charge the same rate per shirt.B.Those two vendors charge the same flat rate for artwork.C.Those two vendors will have the same total cost to produce one shirt.D.Those two vendors will charge the same total cost for any size job.
