Answer:

Step-by-step explanation:

you have to make a box like this:

║ ---------- ║------------ ║ label one side percent and the other amount

║ x% ║ 96 kg ║

║ _ _ _║_____ _║ Now if the patient originally weighed 102 kg which

║100% ║ 120 kg ║ is 100% place the numbers in the bottom box.

║ _ _ _ ║ _ _ _ ║ and if the patient currently weighs 96 kg then let

Percent Amount percentage of the weight lost be x. Now cross multiply. You should get 100*96=120*x. Simplify that to get 9600=120x, now divide by 120 on both sides and you get 80 so x= 80. But the problem isn't done yet. Now you have to subtract 80% from 100% to find the weight lost, because 80% is the percentage of the current weight. after you have subtracted you get 20

20% of the original weight was lost.

A town has a small zoo. These two lists show information about the zoo.

Natasha_Volkova [10]

Answer:

For which list does the total number have meaning? (What to see at the zoo)

For the list of facts it (does not) make sense to add the cost of a past, the area and the employees because these quantities (cannot) be expressed using the same unit. The number of 168 (does not) have meaning for the list

Step-by-step explanation:

Area is usually described in square feet while a population has no unit and a price is described in dollars therefore the list of facts has no meaning ( i got this question correct)

The sanitation department calculated that last year each city resident produced approximately 1.643 × 103 pounds of garbage. The

bija089 [108]

Given that, according to sanitation departments report; the samount of garbage produced by 1 resident $= 1.643 \times 10^3$ pound.

Given that population of the city $= 2.61 \times 10^5$

Now we have to find how much garbage did the city sanitation department collect last year.

To find that we just need to multiply the garbage produced by 1 resident with the population of the city.

Total garbage collected $= (2.61 \times 10^5 ) * (1.643 \times 10^3 )$ pounds

Total garbage collected $= (2.61*1.643) \times 10^{5+3}$ pounds

Total garbage collected $= 4.28823 \times 10^8$ pounds

Hence final answer is $4.28823 \times 10^8$ pounds.

Equation represents the difference in the number of foreign and domestic stamps Malik collected: X-34=y

equation represents the total number of stamps Malik collected:
212 = X-34-y
so,
245= X-Y

Situation :
Y= X-34
X-Y= 245

Mr Chua borrows a sum of money from the bank which charges a compound interest of 4.2% per annum, compounded 6.Given that Mr Chu

Inessa [10]

Answer:

Original sum of money = $2246.51

Step-by-step explanation:

Interest = $96.60

Interest is compounded 6 times in a year ; n = 6

time = 1 year ; Rate of interest (r) = 4.2%

Interest = Future Value - Principal Value ...........(1)

$\text{Future Value = }Principal\cdot (1+\frac{r}{100\times n})^{n\cdot t}\\\\\text{Substituting this value in equation (1) , We get }\\\\Interest=Principal\cdot (1+\frac{r}{100\times n})^{n\cdot t}-Principal\\\\\implies 96.60=Principal[\cdot (1+\frac{4.2}{100\times 6})^{6\cdot 1}-1]\\\\\implies Principal=\$2246.51$

Hence, the original sum of money borrowed = $2246.51
