Solve. A standard coffee mug has a capacity of 16 fluid ounces. If Annie needs to fill 6 mugs with coffee, how many total quarts of coffee does she need?

Answers

Answer: 3 quarts of coffee.

Step-by-step explanation:

A coffee mug can take 16 fluid ounces.

Annie needs to fill up 6 mugs so the total ounces needed for 6 mugs would be:

Rapid Rental Car charges a $55 rental fee, $20 for gas, and $0.65 per mile driven. For the same car, Capital Cars charges $55 for rental and gas and $0.75 per mile.

Answers

Answer:

200 miles

Step-by-step explanation:

Given data

Rapid Rental Car

charges a $55 rental fee

$20 for gas, and

$0.65 per mile driven

let the number of miles be x, the total charges y

y=55+20+0.65x

y= 75+0.65x----------1

Capital Cars

charges $55 for rental and gas and

$0.75 per mile.

let the number of miles be x, the total charges y

y=55+0.75x

y= 55+0.75x----------2

Required

The number of miles driven before the two Rental companies charge the same amount

equate 1 and 2

75+0.65x= 55+0.75x

collect like terms

75-55= 0.75x-0.65x

20= 0.1x

x= 20/0.1

x= 200miles

Hence the distance will be 200 miles for the charges to be the same

O x + 10 = x2 + 2x + 1
O x + 10 = x2 + 1
O x + 10 = x2-1

Answers

Answer:x + 10 = x2 + 2x + 1 x + 10 = x2 + 1 x + 10 = x2 – 1.

Step-by-step explanation:

The solution is, x+10 = x^2 + 2x + 1 is the equation is related to

√x+10  - 1 = x.

What is  simplification?

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here, we have,

given that,

the equation is,

√x+10  - 1 = x

or, √x+10 = x+1

now, taking square on both side, we get,

x+10 = (x+1)^2

we have,

(a+b)^2 = a^2 + 2ab + b^2

so, applying that, we get,

x+10 = x^2 + 2x + 1

Hence, The solution is, x+10 = x^2 + 2x + 1 is the equation is related to √x+10  - 1 = x.

Y = 1/2x + 3 on a graph

Answers

Answer:

Step-by-step explanation:

What is the question? If you want to know how to graph this equation, it's usually easiest to start with the intercepts, i.e., the points where the line crosses the axes.

y  = ½x + 3 tells you that the line crosses the y-axis at (0,3), so plot that point.

Then let y = 0 and solve for x.

0 = ½x + 3

x = 6

The line crosses the x-axis at (6,0), so plot that point as well.

Then draw the line passing through those two points.
