Answer:

if 4:5:3=84 you start by adding (4+5+3=9)....so 9 equals to 84 what about (4) cross multiply....you will 4=28 .....if 9 =84 what about 5 cross multiply.....you will get 35....if 9 =84 what about 3

cross multiply.....you will get 21 so the numbers are.

4=38

5=35

3=21

Answer:

i guess there is no difference even if u bought two 10 inch pizza which would totally cost $22 and one 20 inch pizza which is also $22.....

By knowing how to use positive numbers and negative numbers, we will see that the answers are:

By standard notation, if May wins money, then we represent this with a positive number.

While if she pays or has a debt, we represent the change with a negative number (because now she has less money than before).

A) She receives $25, so the change is:

C = $25

B) She earns $14, so the change is:

C = $14

C) She spends $10, so now she has $10 less than before, the change is:

C = -$10

D) She donated $3, so the change is:

C = -$3

E) She gots $2, then the change is:

C = $2.

Answer:

it is IH - 110 ft

Step-by-step explanation:

The plane height is down 110 feet from its initial height.

Subtraction is mathematic operation. Which is used to remove terms or objects in expression.

Let x be the initial height of the plane.

Then according to question;

if drop down means height in negative term and rise up means height in the positive term.

Then,

the height is

= x -300-180+240+130

= x-110

Therefore, down 110 feet is the height of the plane now relative to its initial height.

Answer:

24 Minutes

Find 60 percent of 40.

Percent means over 100

,so 60% = 60/100 or 0.6

Multiply that by 40 to find 60% of it:

40 * 0.6 = 24

A Samantha spent percent 24 minutes on language arts out of the 40 minutes dedicated to her homework.

To find the number of minutes Samantha spent on language arts,  to calculate 60% of the total time  spent on homework.

Samantha spent a total of 40 minutes on homework.

To find 60% of 40 minutes, multiply 40 by 0.60 (since 60% is equivalent to 0.60):

60% of 40 = 0.60 × 40 = 24 minutes

Therefore, Samantha spent 24 minutes on language arts.

Regarding the 2-column table provided, it appears to be unrelated to the problem and does not directly provide information about Samantha's homework time.

Answer:

1st option

Step-by-step explanation:

the figure is a kite

the horizontal diagonal bisects the vertical diagonal , then

x = 5

The diagonals are perpendicular , so using Pythagoras' identity

x² + y² = 13²

5² + y² = 13²

25 + y² = 169 ( subtract 25 from both sides )

y² = 144 ( take square root of both sides )

y = [tex]\sqrt{144}[/tex] = 12

Answer:

x = 3, x = 1

Step-by-step explanation:

Okay, let's set the equation = 0:

3x^2 -12x + 9 = 0

Then, we factorise. To do this, we have to find 2 numbers which have a product of 9 and add up to -12. There are a few ways to do this, but a simple try and error is the easier when using numbers which don't have many factors. So here we know that to get a product of 9, there are only 2 options: 9*1 and 3*3. Now we have to figure out which of these add up to -12. But to do this, we have to take into account the 3, from the x^2 coefficient. This allows to know that the numbers will be 9*1. Then we just need to change the signs to make it work. This would give: -9*-1 (with 3*-1).

The fully factorised equation would be (3x-9)(x-1). Following this, you can always expand it quickly, to check that it really works correctly.

Now let's solve. (3x-9)(x-1) = 0

We say that when two numbers multiplied by each other equal to zero, one of them has to be zero. So if (3x - 9) was equal to 0:

3x - 9 = 0

3x = 9

x = 9/3

x = 3/1

x = 3

Now for the other:

x - 1 = 0

x = 1

Step-by-step explanation:

No. of students = 32
No. of students in each group = 5
No. of students  in ONE group = 7
No. of groups of 5 = 32 - 7
                               = 25
                               = 25/5 = 5

Answer:

Exact: 9.42

Approx: 9

Step-by-step explanation:

The area of a circle is pi*radius^2 (pi=3.14 r=radius ^2= power of 2/squared)

The diameter is two times the radius. So, we need to divide the diameter by two for the first step of solving this.

6/2=3

Now, we know the radius is 3.

Let's square it:

3^2= 3*3

3*3=9

Now, the last step is to multiply it by pi (3.14)
3.14*3=9.42

There we go! The area is 9.42 feet!

53.55 / 85 = 0.63

0.63 * 100 = 63

63 - 38 = 25
