Answers

Answer 1

Answer: If you take the numerator and the denominator from flour and multiply both by 10, you'll get 40/100. then, add 40/100 to 12/100. your answer should be 52/100. if not, look back through your math. hope that helped.

You round 1 1/8 to 1 and 9/10 to 1 (since you are estimating) and then you add 1+1+1+1, which is 4 because to find perimeter you add the lengths and the widths together.

Rearrange the equation A = xy to solve for x.x = y over A
x = A times y over x
x = A times x over y
x = A over y

Answers

Answer:

x = A over y

Step-by-step explanation:

we have

$A=xy$

Solve for x

That means -----> isolate the variable x

Divide by y both sides

$A/y=xy/y$

Simplify

$A/y=x$

Rewrite

$x=A/y$

therefore

x = A over y

Answer:

The correct option is D) x = A Over y.

Step-by-step explanation:

Consider the provided equation.

$A = xy$

We need to solve the equation for x.

Divide both the sides by y.

$(A)/(y) = (xy)/(y)$

$(A)/(y) = x$

$x=(A)/(y)$

Hence, the value of the provide equation for x is $x=(A)/(y)$ .

Thus, the correct option is D) x = A Over y.

Two problems here- 1) Find the total cost to the nearest cent, $100 dinner; 20% gratuity 2) Find the total cost to the nearest cent, 12300 car; 5% sales tax

Answers

In both of these problems you are asked to find a percentage of another number and then add it to that number... In math

"is" means =
"of" means ×

1) In the first problem 20% of 100 is, means
20% × 100 =
.20 × 100 = $20

now add it to the cost of the meal.

100 + 20 = $120 (final cost)

___________________

2) In the second problem 5% of 12300 is, means
5% × 12300 =
.05 × 12300 = $615

add this to the original price for the final cost...

12300 + 615 = $12,915

When 4((0.5 x + 2.5 y minus 0.7 x minus 1.3 y + 4)) is simplified, what is the resulting expression?

Answers

Answer:

$-0.8x + 4.8y + 16$

Step-by-step explanation:

We have to simplify the given expression:

$4(0.5x + 2.5y-0.7x-1.3y+4)$

First we group all the like terms of x.

$4((0.5x-0.7x) + 2.5y-1.3y+4))\n=4(-0.2x+ 2.5y-1.3y+4)$

Next we group all the like terms of y.

$4(-0.2x+ (2.5y-1.3y)+4)\n=4(-0.2x+1.2y+4)$

Now, we use distributive property for the multiplication,

$4(-0.2x+1.2y+4)\n=(4* -0.2x) + (4* 1.2y) + (4* 4)\n=-0.8x + 4.8y + 16$

is the required simplified expression.

Answers

Using quadratic formula:
2(x^2-2x + 1) +4=16
2x^2-4x+6=16
2x^2-4+6-16=0 (then divide both sides by 2)
X^2 -2x- 5= 0
Then use quadratic formula

Dustin and Melanie are playing a game, where two standard, six-sided number cubes are rolled, and the sum of their outcome is found. Each player gets a chance to guess the correct sum, and the player that guesses the correct sum wins. Dustin decides to guess a sum of six. Melanie decides to guess a sum of seven. Which player made the better decision

Answers

Answer:

Melanie.

Step-by-step explanation:

The possible ways of getting a 6 are (3,3), (2,4), (4,2), (1,5) and (5,1).

That is 5 ways.

The possible ways of getting a 7 are (1,6), (6,1), (5,2),( 2,5), (3, 4), (4,3).

That is 6 ways.

So Melanie made the better decision.
