Answer:the smallest possible sum of the two numbers is 537

Step-by-step explanation:

Two three-digit numbers are made up of six different digits.

To interpret this, let the two three digit numbers be;

ABC and. DEF

The first digit of the second number is twice as big as the last digit of the first number.

Interpret;

D=2C

The first digit of the first number can be 1, the second digit 0 and the third digit 2.

102.

For the second number:

D=2C

The first digit is 4, second digit 3 and last digit 5 since no repetition of digits

435.

Answer:the smallest possible sum of the two numbers is

102+435= 537

o-na [289]

Answer:

Number of students= 820.64 = 821

Step-by-step explanation:

Giving the following information:

Current attendance= 950 students

Number of periods= 3 years

Decrease rate= 5%

To calculate the number of students in attendance in 3 years, we need to use the following formula:

Number of students= current attendance*(1+decrease rate)^(-n)

Number of students= 950*(1.05^-3)

Number of students= 820.64 = 821

Ilya [14]

Question is not proper, Proper question is given below;

For a birthday party, Mr. Perkins orders 8 chocolate chip cookies and 16 sugar cookies. Each cookie is the same price. He also picks up a cupcake for himself, which costs $2.75. The total bill is $44.03. What is the cost of a cookie?

Answer:

The Cost of the cookie will be $1.72.

Step-by-step explanation:

Given:

Mr Perkins orders 8 chocolate chip cookies and 16 sugar cookies.

Since cost of both the cookies are same then Let us assume the cost of cookies be 'x'.

Total cost of the cookies = $(8 + 16)x = 24x$

Cost of Cup cakes = $2.75.

Total bill he pays = $44.03

We need to find the cost of each cookies.

Now we know that Total bill he pays is equal to sum of Cost of cookies and Cost of Cup cakes he bought.

Framing in equation form we get;

$44.03 = 24x + 2.75$

Now Subtracting both side by 2.75 using Subtraction property we get;

$2.75+24x-2.75 = 44.03 - 2.75\\\\24x = 41.28$

Now Dividing both side by 24 using Division property we get;

$\frac{24x}{24} = \frac{41.28}{24}\\\\x=1.72$

Hence The Cost of the cookie will be $1.72.

Use your answer from Part I to find the slope of a line going through each set of points. Then

Zinaida [17]

Answer:

Step-by-step explanation:

to find the slope of a line that passes for two given points we can use this formula (y2-y1)/(x2-x1). x and y inidcate the coordinates of the two points.

A (-2-7)/(-4-5) = (-9)/-9 = 1 (m is positive)

B (-10-3)/(1-1)) = the denominator is equal to zero, so the division is impossibile. This mean that m is undefined and the line is parallel to y axis
