Answer:

41235

Step-by-step explanation:

There are 120 five-digit numbers that can be made from the digits 1, 2, 3, 4, 5 if each digit is used once in the number,

The total number of times where each number will occur or be at first place is calculated as:

4! = 4 × 3 × 2 × 1

= 24

Hence,

24th number = The last number where 1 is at first place

We can write this out as:

12345

12354

12435

12453

12534

12543

13245

13254

13425

13452

13524

13542 e.t.c.

48th number = The last number where 2 is at first place

72nd place = The last number where 3 is at first place.

This means, the 73rd number is the first number where 4 is at first place.

Therefore, the 73rd number based on pattern is 41235

anna is buying a house selling for 185,000. to obtain the mortgage, anna is required to make a 20% down payment. anna obtains a
JulsSmile [24]

Answer:

a. The Amount of the required down payment is $37,000

b. The amount of the mortgage is $148,000

c. The monthly payment for principal and interest is $953.62 per month

Step-by-step explanation:

a) In order to calculate the Amount of the required down payment  we would have to use the following formula:

Amount of down payment = Value of home x Required down payment percentage

= $185,000 x 20%

= $37,000

b)  In order to calculate the Amount of the mortgage we would have to use the following formula:

Amount of the mortgage = Value of home – Down payment

= $185,000 - $37,000

= $148,000

c)  Loan Amount (P) = $148,000

Monthly Interest Rate (n) = 0.5% per month [6.00% / 12 Months]

Number of months (n) = 300 Months [25 Years x 12 Months]

Therefore, the Monthly Loan Payment = [P x {r (1 + r)n} ] / [(1 + r)n – 1]

= [$148,000 x {0.005 x (1 + 0.005)∧300}] / [(1 + 0.005)∧300 – 1]

= [$148,000 x {0.005 x 4.464}] / [4.464 – 1]

= [$148,000 x 0.02232] / 3.464

= $3,303.36 / 3.464

= $953.62 per month

The monthly payment for principal and interest is $953.62 per month

Dennis and Ivy share some sweets between them in the ratio 7:4 Dennis got 42 sweets. How many does ivy get
MrRa [10]

Answer:

Ivy = 24

Step-by-step explanation:

Given

Dennis : Ivy = 7 : 4

Required

Determine the amount of sweet Ivy gets when Dennis = 42

We have:

Dennis : Ivy = 7 : 4 and

Dennis = 42

Substitute 42 for Dennis in Dennis : Ivy = 7 : 4

42 : Ivy = 7 : 4

Convert to fraction

\frac{42}{Ivy} = \frac{7}{4}

Cross Multiply:

Ivy * 7 = 42 * 4

Divide through by 7

\frac{Ivy * 7}{7} = \frac{42 * 4}{7}

Ivy = \frac{42 * 4}{7}

Ivy = 6* 4

Ivy = 24

write the equation in standard form of the line that passes through the point (1,26) and has a slope of -0.4
katovenus [111]
The beginning formula that you start with is y=m(x)+b
after the problem is written into the formula your ready to start.

It should look like this:

26y=-0.4(1)+b

to get the entire formula you've gotta find the
y-intercept or "b"

to start solving multiply the "m" by the "x" A.K.A:

-0.4×1

you should come up with the answer -0.4 since everything multiplied by 1 is still the same thing depending on if its positive or negative

after you've finished solving the multiplication part the equation should look slightly different like this:

26y=-0.4+b

the next step is the get "y" by itself since right now is a variable.

also you should always remember what ever process of simplifying by the same number to get rid of it in a "y=m(x)+b" equation should be done the same to the other side

take a look at the "-" sign in front of 0.4 this would mean that you are going to do the oppisite opperation to cancel it out so you would be adding the same number to either side. after adding the -0.4 to itself that would leave "b" by itself the problem should now look like this:

(26y+0.4)=b

forget about the y for now and focus on the (26+0.4)
you should get 26.4=b

insert this into the original equation of "y=m(x)+b" and this should look like this:

y=-0.4(x)+12.4
