Answer:

1.7

Step-by-step explanation:

2.5÷1.5

5/3

1.66666

1.7

The divisions of 2.5 divided by 1.5 gives to 5/3 or 1.6667.

One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things.

Given:

2.5 divided by 1.5

So, 2.5 / 1.5

= 25 x 10 / 15 x 10

= 25/15

= 5 x 5 / 5 x 3

= 5/3

Hence, the divisions results to 5/3 or 1.6667

Answer:

Step-by-step explanation:

From the given information;

since;

1 feet = 12 inches long

Then, 4 feet = (4 × 12)inches long

= 48 inches long

Thus, the length of the remaining piece is calculated as follows:

Length of remaining piece = Total length of piece - (piece that was being cut + width )

[tex]= 48 - (14 \dfrac{1}{4}+ \dfrac{1}{8})[/tex]

[tex]= 48 - ( \dfrac{57}{4}+ \dfrac{1}{8})[/tex]

[tex]= 48 - ( \dfrac{114+1}{8})[/tex]

[tex]= 48 - ( \dfrac{115}{8})[/tex]

[tex]= \dfrac{269}{8}[/tex] inches

Answer:

[tex]\frac{2}{7}[/tex]

Step-by-step explanation:

In order to find the slope of a line you must find where the points intersect, use the formula for slope, substitute values, and simplify if needed.

In this case we were already given the points for slope:

[tex]P1=(-4,-4) = (x1,y1)[/tex]

[tex]P2=(-2,3)=(x2,y2)[/tex]

Slope formula:

[tex]slope = \frac{y2-y1}{x2-x1}[/tex]

Now substitute:

[tex]\frac{-2--4}{3--4}[/tex]

Solve using KCC: (Keep, Change, Change)

[tex]-2+4=2[/tex]

[tex]3+4=7[/tex]

=[tex]\frac{2}{7}[/tex]

Because the slope isn't a negative you do not need to simplify the answer.

Hope this helps.

Answer:

y= -2

x = 5

Step-by-step explanation:

Multiply the top equation by 2 to get

2x + 6y = -2

then subtract the bottom equation by the new equation to get

2x + 6y = -2

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

2x + 2y = 6

which is

4y = -8

y = -2

If y = -2

Then plug -2 into y in the top equation to get x + 3(-2) = -1 and simplify which is

x + (-6) and add 6 to both sides to get x = -1 + 6

which is x = 5

it is a. Yes it can, because −2.5 lies to the left of −0.5. plz mark me as brainiest and tell me if I am wrong

Step-by-step explanation:

The Magnitude of a Complex Number

A complex number is expressed in rectangular form as:

[tex]Z=a+ b\mathbf{ i}[/tex]

The absolute value or magnitude of Z is calculated as follows:

[tex]\mid Z\mid=\sqrt{a^2+b^2}[/tex]

We are given the number

[tex]Z=-4-\sqrt{2}\mathbf{ i}[/tex]

Here: a= -4, b=[tex]-\sqrt{2}[/tex]

Calculating the absolute value:

[tex]\mid Z\mid=\sqrt{(-4)^2+(-\sqrt{2})^2}[/tex]

Operating:

[tex]\mid Z\mid=\sqrt{16+2}=\sqrt{18}[/tex]

Factoring 18:

[tex]\mid Z\mid=\sqrt{3^2*2}[/tex]

Taking the square root of 3^2:

[tex]\mid Z\mid=3\sqrt{2}[/tex]

Answer:

D

Step-by-step explanation:

So you are looking for the inverse equation. The original can be written as y=1/2x-6. For the inverse, your variables switch places. It's reflecting across the line y=x (that's what the inverse does). So you write it as x=1/2y-6. Now solve for the new equation:

Move 6 over: x+6=1/2y

Isolate y: 2(x+6)=y

This gets you D.

Answer:

Joey's Cafe sold 20% regular coffee and 80% decaffeinated coffee.

Step-by-step explanation:

We are given that the cafe served 35 coffees. We are also told that of those 35 coffees, 7 coffees were regular.

Therefore, we can divide the number of regular coffees by the total number of coffees sold to get the percentage of regular coffees.

Our ratio will be set up as 7 regular coffees : 35 total coffees. We can also represent this as a fraction.

[tex]\displaystyle\frac{7}{35}=\frac{1}{5}\\\\\frac{1}{5}=0.2\\\\0.2 \times 100 = 20\%[/tex]

Therefore, of the coffees sold at the cafe, 20% of those coffees were regular.

Additionally, we can subtract this percentage from 100 to find out how much of the sales were decaffeinated coffee.

[tex]100\% - 20\% = 80\%[/tex]

Joey's Cafe sold 80% decaffeinated coffee.
