Answer:

66.390

Step-by-step explanation: 66.389 the 9 is thousandths, it rounds up to 66.390

Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.

It is the sum of each separate rate.

In this problem, the rates are given by:

Hence the together rate is given by:

[tex]\frac{1}{x} = \frac{1}{6} + \frac{1}{6} + \frac{1}{4}[/tex]

[tex]\frac{1}{x} = \frac{1}{3} + \frac{1}{4}[/tex]

[tex]\frac{1}{x} = \frac{4 + 3}{12}[/tex]

7x = 12

x = 12/7

x = 1.71.

They would prepare the solution in 1.71 minutes working together.

Step-by-step explanation:

I am not sure this is a square.

this could be a rectangle.

to be safe, I am following that path.

in a rectangle opposite sides are of equal length.

that means

y - 1 = 2y - 7

y = 2y - 6

0 = y - 6

y = 6

3x - 4 = 3y - 13

3x - 4 = 3×6 - 13

3x - 4 = 18 - 13 = 5

3x = 9

x = 3

as it turns out, it is a square, so we could have used every side expression to be equal with every other side expression, but better safe than sorry ...

Answer: On her math test, Elliana gets 6 questions wrong, or 15% of the total questions. How many questions are on the test?

Esplaination: She has 40 questions on the test because she has 40%/100  or 2/5 20x5=100 and 2x20=40

BTW the question is made up and goes togethetr with the bottom.

Answer:

A. p=0.42n

Step-by-step explanation:

2.52/6 = $0.42

$0.42 = the cost of one oranges

So,

To find the cost of n oranges you need to multiply it by 0.42

P=0.42 x n

Ex. Find the price of 4 oranges

So you're going to multiply 4 by 0.42 to get the cost of 4 oranges that will equals $1.68

The answer is p=0.42n

Answer:

Answer:

2x+8=11

Step-by-step explanation:

The equation 2x + 8 = 11 would be the answer.

2 (coefficient) ----> it would multiply by the unknown value represented by the common variable "x".

Because in the given situation, it says twice (means 2 multiplied by a number or a number multiplied twice by itself) then multiplication would be the order of operation used between the 2 and x.

The "and" indicates the order of operation addition, as it is proven as the only given options for the answer all equal 11.

Therefore, proving that option A is the answer.

Answer:

The area is 64.

Step-by-step explanation:

First find the area of the simple shape in this case the regtangle so you would do 12 × 6 which equals 72. Then find the area of the shape that is taken away which is a triangle. In order to find the area of the triangle do 8×2÷2 which would equal 8. Finally do 72 - 8 and get your answer of 64.

Answer:

Step-by-step explanation:

Using the Theorem,

BA*AD=CA*AE

3x+2*6=4x-2*8

18x+12=32x-16

12+16=32x-18x

28=14x

BD= BA+AD

3x+2+6

3(2)+2+6

6+2+6

Step-by-step explanation:

Step-by-step explanation:

he buys 48 bottles for $18.50.

FYI : that means he gets them for

18.5/48 = $0.385416666... per bottle

he sells all 48 bottles for $1.25 per bottle.

that means the revenue (or selling income) is

48 × 1.25 = $60.00

profit is now income minus basic costs :

profit = 60 - 18.5 = $41.50

Answer:

y = 3x - 1 .

Step-by-step explanation:

The general  point-slope form is y = mx + c where m = slope and c is the y-intercept

As we are given the slope and one point we first use the point-slope form:

y - y1 = m(x - x1)

y - 5 = 3(x - 2)

y = 3x - 6 + 5

y = 3x - 1   (Answer).

answer would most likely be C
