Multiply. ?2 3/5 ? 5/6 ? Express your answer in simplest form.

The value of 5 is hundredths

Answer:

A.(0, –5)

Step-by-step explanation:

Here we are given the expression:

[tex]x^{2}+18[/tex]

Now let us equate it to zero to find x first,

[tex]x^{2}+18=0[/tex]

Now subtracting 18 from the other side,

[tex]x^{2}=-18[/tex]

taking square root on both sides,

So we will get two values of x as ,

[tex]x=3\sqrt{-2}[/tex]

[tex]x=-3\sqrt{-2}[/tex]

Now we can write square root -1 as i,

So our factors become,

[tex]x=3i\sqrt{2}[/tex]

[tex]x=-3i\sqrt{2}[/tex]

Answer:

The final factored form becomes,

[tex](x+3i\sqrt{2})(x-3i\sqrt{2})[/tex]

Answer:

[tex](x+3i\sqrt{2})(x-3i\sqrt{2})[/tex]

Step-by-step explanation:

1. You must apply the Quadratic formula, which is:

[tex]x=\frac{-b+/-\sqrt{b^{2}-4ac} }{2a}[/tex]

2. Substitute values:

[tex]a=1\\b=0\\c=18[/tex]

[tex]x=\frac{-0+/-\sqrt{0^{2}-4(1)(18)} }{2(1)}\\x=\frac{+/-\sqrt{-72}}{2}\\x=\frac{+/-6i\sqrt{2}}{2}\\x=+/-3i\sqrt{2}[/tex]

3. Finally, you obtain:

[tex](x+3i\sqrt{2})(x-3i\sqrt{2})[/tex]

Answer:

0.85 mile(rounded to nearest hundredth)

Step-by-step explanation:

We have to convert 1500 yards into miles.

To convert 1500 yards into miles, we first need to know the relation between yards and miles.

So we have,

[tex]1 \:\text{mile}=1760\:\text{yards}[/tex]

Now, to convert 1500 yards into miles, we need to know how many miles are there in 1 yard.

So, we have

               [tex]1\:\text{yard}=\frac{1}{1760} \:\text{miles}[/tex]

[tex]\implies1500 \:\text{yards}=\frac{1500}{1760} \:\text{mile}[/tex]

[tex]\implies1500 \:\text{yards}=\frac{150}{176} \:\text{mile}[/tex]

[tex]\implies1500 \:\text{yards}= \frac{75}{88}\:\text{mile}[/tex]

[tex]\implies1500 \:\text{yards}= 0.85\:\text{mile}[/tex]

Hence, 1500 yards is 0.85 mile, rounded to nearest hundredth.

The area of a rectangle is the width times the length:

[tex] A = w\cdot l \iff 228 = w\cdot 12 \iff w = \dfrac{228}{12} = 19 [/tex]

The perimeter is twice the sum of the dimensions:

[tex] 2p = 2(12+19) = 2\cdot 31 = 62 [/tex]

The perimeter of the rectangle with dimensions 19 ft*12 ft comes to be 62 square feet.

Suppose the breadth of the rectangle is x.

The perimeter of a rectangle is the sum of all its sides i.e. the sum of two lengths and two breadths.

If length and breadth are a and b respectively then perimeter =2(l+b).

According to the question

Length =12 ft

Area=228 square ft

So, length * breadth = 228

[tex]12x =228[/tex]

[tex]x=\frac{228}{12}[/tex]

x=19

So, breadth of the rectangle =19 ft

So, perimeter = 2(12+19) = 62 square feet.

Hence, the perimeter of the rectangle with dimensions 19 ft*12 ft comes to be 62 square feet.

Answer: Hello mate!

first, let's do a list with all the things we know about this problem:

Both trains depart at the same time; we can define this time as t = 0 in hours.

the velocity of train A is 50mph

the velocity of train B is 60mph

both trains travel in opposite directions.

the initial distance between both trains is equal to 330 miles:

we want to know when the trains will meet each other:

The trains will meet each other when the sum of their traveled distance is equal to the initial separation between them.

the distance traveled by the train A is equal to his velocity multiplied by the time that passed since it departed.

this is: Da(t) = (50*t)mi

and the distance for the train B is: Db(t) = (60*t)mi

then, as we know, the trains will meet when Da(t) + Db(t) = 330mi

then 50*t + 60*t = 330

110*t = 330

t = 330/110 = 3h

the trains will meet 3 hours after they departed.

Add 5 to both sides.

First we have to see which is the right angle.  This triangle has its legs oriented parallel to the axes. (-3,-1) and (1,-1) form the horizontal leg, (1,-1) and (1,2) the vertical leg.  

So the right angle vertex is (1,-1) and the hypotenuse endpoints are (-3,-1) and (1,2)

The length is given by

[tex]d = \sqrt{ (1 - -3)^2 + (2 - -1)^2} = \sqrt{4^2+3^2}=\sqrt{25} = 5[/tex]

This is a 3/4/5 right triangle.

Answer: 5

All we have to do is divide 120 by 15

120 ÷ 15 = 8

Therefore, it will take 8 hours to drive 120 miles at a speed of 15 mph

Hope this helps

15miles = 60minutes

divide 15 by 120 which equals 8

8 times 60 equals 480

Given function: P(x) = -10x + 80.

Where function represents the amount of granola, in ounces and x represents the number of ounces Paula puts in each bag.

Range of the function is the values of the function we would get.

That is the amount of granola in ounces for different x values.

For x=0 the number of ounces would be -10(0)+80 = 80.

And for x=8, it would be -10(8) + 80 = 0.

But even we could take decimal values too.

Like x=0.5 ounces, x=0.55 ounces etc.

And that 0.55 would give a decimal value.

Therefore, we can take any real number for x between 0 and 8.

But we need to find the range.

So, the range would be between 0 and 80 and it could be any real number.

Therefore, correct option is :

To solve this problem you must think in this way.

First we see that function y is greater than 3-x, conclusion is the following

shaded area must be above function. That condition is satisfied by the graph 3 and 4.

Then we write inequality in the slope form  y> -x+3.

We see that the coefficient of direction is -1 (negative) which mean that the graph is decreasing. That condition is satisfied by the graph No 4.

The correct answer is graph number 4 ( or D.)

We have the equations: l = 2b and 2l + 2b = 228;

Then, 4b + 2b = 228;

6b = 228;

Answer:

4/9 probability

Step-by-step explanation:

Imagine winning something, there's 3 possible prizes that you get to choose from and get to keep let's say 4 days? These all written on the paper that you must pull from a box.

Your three prizes are

             D1    D2   D3    D4

1. a car

2. a bike

3. skateboard.

Now if you can imagine a grid and you mark 1 dot in each day we'll end up with 12 slots total.

Let's say you don't want a skateboard you rather have a car or a bike. We need to figure out of the 12 possibility (assuming all are equal) What's the possibility of you pulling out anything BUT a skateboard?

You want at least 3 days in either or. So we must find P = (Days without skateboard)

We know it's all equal outcomes, you're going to get 1 day of that 1 item.. soo..

p (DWS) = _____

                 12 outcomes

Now you want how many days MORE THAN 3, can you use anything but the skateboard?

You have 3 & 4 days with a car...

You have 3 or 4 days with a bike.. Which gives us 4 of the days we do want!

Giving your final problem the looking like this .. P(DWS) = 4/9

The midpoint of a line segment using paper folding constructions yes it is true.

Comparable to mirroring one side of a plane in a crease, folding paper. So, to fold is to map one half of a plane onto another while also creating a crease.

The steps used to create a mid-point are given below:-

1. The top of the paper lies in itself; hence, we can say that the line segment lies in itself.

2. You have a new line at the centre of the paper. The point at the top of this centre line is the midpoint of the line segment.

3. The edges that lie on each other translate to the endpoints lying on each other.

Step-by-step explanation:

If we look at the information it says:

Facility rental is dependent upon number of hours we are renting the facility for.

Linen, food, and decoration also depends upon the number of attendees. Also, the table decorations depend upon the number of attendee.

The things that are independent of the number of attendees are entertainment and cleaning fee. These are fixed charges.

So, the total cost for entertainment and cleaning are the constants in the expression. This is the amount that will remain constant regardless of the number of attendees.
