Answer: A-(40)(108) and

C-(40)(33)+(40)(75

Step-by-step explanation:

Hello! I believe that I have the answer.

My answer: The total amount was $47.79.

8% of $37.50 is $3. $37.50 + $3 = $40.50.

18% of $40.50 is $7.29. $40.50 + $7.29 = $47.79.

I hope that helps! Please let me know if my answer is incorrect.

Answer:

[tex] \rm Numbers = 4 \ and \ -3.[/tex]

Step-by-step explanation:

Given :-

And we need to find out the numbers. So let us take ,

According to first condition :-

[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]

Hence the numbers are 4 and -3

Step-by-step explanation:

[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]

Answer:

The distance between Points A and B is 1.

Step-by-step explanation:

Given that Point A is located at -0.75 and Point B is located at 1/4 on a number line, to determine which expression shows how to find the distance between points A and B the following calculation must be performed:

1/4 = 0.25

-0.75 + X = 0.25

X = 0.25 - (-0.75)

X = 0.25 + 0.75

X = 1

Therefore, the distance between Points A and B is 1.

Answer:

25

Step-by-step explanation:

Answer: I belive this is 25

Step-by-step explanation:

for 125 and 175 is 155 and 75 is excluded

Answer:

Step-by-step explanation:

1) x +22.5 = 49.25

Subtract 22.5 from both sides

x + 22.5 - 22.5 = 49.25 - 22.5

x = 26.75

Checking:  LHS = x + 22.5 = 26.75 + 22.5 = 49.25 = RHS

2) 37.2 = n - 12

Add 12 to both sides

37.2 + 12 = n - 12 + 12

49.2 = n

n = 49.2

3) 55t = 176

Divide both sides by 55

[tex]\frac{55t}{55}=\frac{176}{55}\\\\t = 3.2[/tex]

Answer:

n=2

Step-by-step explanation:

Answer:

The answer is n=2.

Step-by-step explanation:

First, combine like terms, so the problem then looks like 3.6n-0.12=7.08.

Then, add 0.12 to both sides, which now looks like 3.6n=7.2.

Finally, divide both sides of the equation by 3.6, and the final answer is n=2.

Answer:

30

Step-by-step explanation:

Lets use the formula BEDMAS:

-6 × -3 = 18 (Since two negatives equals a postive)

18 - 8 = 10

We have a first bracket done, so lets do the next one:

-6 ÷ -2 = 3

-----------

In the middle, the is a multiply symbol, so

10 × 3 = 30

Answer:

B

Step-by-step explanation:

I'm pretty sure it's B. Sorry if I'm wrong.

Answer:

wouldn't it be B

Step-by-step explanation:

because the formula is 2pi r  but with the 2 at the bottom the pi r  would be at the top.

Answer: 6.8

Step-by-step explanation:

Add all of them, and then divide them by 8

Answer:

The mean is 6.75

Step-by-step explanation:

There are 8 numbers in the set. Add them all, and then divide by 8.

2 + 5 + 5 + 6 + 8 + 8 + 9 + 11 / 8=54/8=6.75

So, the mean is 6.75!

Hope this answer helps!

Answer:

Part A

Part B

Part C

Part A:

(larger)

(multiply)

(32)

Part B:

you didnt give any context. But to turn pounds into ounces multiply it the pounds by 16 (2lbs. × 16 = 32oz.)

and once you have the total number of ounces divide it by how many ounces her mom drinks in a day (ex. 32÷4= 9) and if that number is larger than 7 then yes, theres enough coffee

The answer is 86

Following PEMDAS, which is:

parentheses

exponents

multiplication

division

addition

subtraction

I found that the answer was 86

Answer:

-10.

Step-by-step explanation:

Step 1: Explain/define

This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.

P (Parenthesis)

E (Exponents)

M/D (Multiplication/division, whichever comes first)

A/S (Addition/subtraction, whichever comes first)

This is the correct sequence of steps when solving expressions with multiple operations.

PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."

------------------------------------------------------------

Step 2: Solve.

REMEMBER PEMDAS!

Expression given: 4 × 3 + 2 × 9 - 40

There are no parentheses.

There are no exponents.

There is multiplication, but no division.

4 × 3 + 2 × 9 - 40

12 + 18 - 40

There is addition and subtraction. Remember to solve whichever comes first.

12 + 18 - 40

30 - 40

30 - 40 = -10.

I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.

Please let me know if you have any further questions.

Answer:

Step-by-step explanation:

B) Small triangle:

height = 20 - 15 = 5

base = 1

height to base =  5 :1

Medium triangle :

height = 60 -30 = 30

base = 2

height to base =  30 :2  = 15 :1

Large triangle:

height = 120 - 60 = 60

base = 4

height to base =  60 : 4 = 15 : 1

c) The ratios are same. This is true because wage and working hours are in direct proportion.

E) Take any two points. (1 , 15) & (2 , 30). Find the slope.

Slope = Change in y ÷ change in x

 m = (30-15) ÷ (2 -1) = 15/1 = 15

y -y1 = m(x -x1)

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x - 15 + 15

y = 15x

Step-by-step explanation:

here, sry for bad writing XD

The scatter plot diagram that represents the data that is shown in the given table is; Attached below

We are told that;

the x-axis represents the beginning balance in thousands of dollars.

the y-axis represents the change in the bank account by hundreds of dollars.

Now, this means the values on the x-axis in plotting order from left to right with their corresponding y-values are;

x - values = 6, 4, 3, 1, 8, 3, 4, 5

y - values = 6, 5, 2, 5, 4, 8, 2, 3

Thus, to plot the scatter diagram, we will enter the corresponding x and y coordinate values which are seen in the scatter diagram attached.
