Answer 1

Given :

A hostel of 500 boys has provisions for 4 days.

To Find :

If the provisions were continued for  20 days, how many students have gone out of the hostel.

Solution :

Let, number of students left after 20 days are x.

Now, provisions are given by :

[tex]\text{Provisions = Number of students}\times \text{Number of days}[/tex]

Also, provisions remains same.

So, initial provision = final provision

[tex]500\times 4 = x \times 20\\\\x=100[/tex]

Therefore, 100 students have gone out of the hostel.

Hence, this is the required solution.

​

Answers

Answer:

h(4)=17

Step-by-step explanation:

Since we are just looking for h(4), all the other equations can be ignored. Then we replace the x in the equation with 4. Remember to do the multiplication before adding the numbers together according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

[tex]h(4)=2*2+7(4)-15\\h(4)=2*2+28-15\\h(4)=4+28-15\\h(4)= 32-15\\h(4)=17[/tex]

Step-by-step explanation:

You bought new furniture with the $3450 that you borrowed from the bank. For 2 years you kept up with the $92.27 monthly payments but then you lost your job. If the bank was charging you a 12.6% interest rate, how much money do you still owe for the furniture

Answers

Answer:

$1670.22

Step-by-step explanation:

In order to solve this probelm we must first calculate the total amount that you  have to pay the bank which would be the amount you borrowed times the interest rate 12.6% or 0.126 (but add the one to add it to the amount borrowed) in decimal ...

$3450 * 1.126 = $3884.70

Now we have to find how much you have already paid by multiplying the amount per month by the amount of months you have paid, since you have been paying for 2 years that means it has been 24 months

92.27 * 24 = $2214.48

Finally we subtract the amount you paid from the total owed to find out how much you still owe

3884.70 - 2214.48 = $1670.22
