The sum of two numbers is 264. One number ends with a zero. If this zero is erased, you get the second number. Find these numbers.

Answers

Answer:

240; 24

Step-by-step explanation:

Given that:

Sum of two numbers = 264

One number ends with '0'

Second number = first number without '0'

Let the first number be 'a'

Since the second number is the first number with '0' erased, then,

Second number = (a ÷ 10)

Therefore, the expression becomes :

a + a/10 = 264

Multiply the equation by 10

10a + a = 2640

11a = 2640

a = 2640/11

a = 240

Therefore ;

a = 240 ;

a/10 = 240/10 = 24

The numbers are 240 and 24

tour takes his dog to be groomed. The fee to groom the dog is $75 plus 6.75 % tax. Is $80 enough to pay for the service? explain

Answers

Tour takes his dog to get groomed on a budget of $80

Now the fee to groom the dog is $75 plus 6.75% tax.
The question asks if the budget is enough to cover the fee.

lets find the total cost:

$75 + ($75 x 0.0675)
= 75 + 5.06
= 80.06

$80 is not enough to pay for the dog to get groomed

Answers

91 you multiply (2x1)+(2x4)+(2x9)+(2x16)+(2x25)+(2x36)=182,then divide the sum by 2,because they're triangles to get 91.

91 is the answer you multiply (2x1)+(2x4)+(2x9)+(2x16)+(2x25)+(2x36)=182,then divide the sum by 2,because they're triangles to get 91.

How to find area of square

Answers

To find the area of a square, remember that a square is a type of rectangle so we can use the following formula to find its area.

Area = length × width

However, since the length and width of a square are always equal, we use a special version of this formula to find the area of a square.

Instead of area = length × width, we say that the area of a square is equal to side × side or s².

I'll show an example.

Image provided.

Since each side of a square is the same, it can simply be the length of one side squared. So multiply the sides by one another say your square had a length of 10 and to find the area multiply the other side length since all squares mostly have the same side length multiply it by ten again and you get 100.

Professor henry knows from past experience that 30% of all homework papers handed in will be missing the name of the person who handed it in. In a class of 200, that is a problem. What is the probability that out of 200 homework papers,a) between 50 and 70 papers will be missing the name
b) at least 75 papers will be missing the name
c) at most 45 papers will be missing the name
d) exactly 65 papers will be missing the name

Answers

If you would like to know how many papers will be missing the name, you can calculate this using the following steps:

30% of 200 homework papers = 30% * 200 = 30/100 * 200 = 60 homework papers

The correct result would be a) between 50 and 70 papers will be missing the name.
