Ummm ima say 12... if he cuts 5 in half that would make 10...add 2 slices(from cutting more)...it would be 12 slices in all.

X<-7

times both sides by 2

2x<-14

add 14 both sides

2x<-14

times both sides by 2

2x<-14

add 14 both sides

2x<-14

QUESTION POSTED AT 28/01/2020 - 01:05 AM

The way tires on wheels work is that when the wheel turns one complete

turn, it moves (forward or backward) by a distance that's the circumference

of the tire.

Now, we know that the circumference of a circle is (π) times the diameter.

The diameter of the tire on this bus is 1 meter. So its circumference is

(π · 1 meter), and every time it turns once, the bus moves 1 meter down

the road.

If the tire rotated 8,000 times, then the bus moved**8,000π meters**,

or**8π kilometers**.

THAT's the**exact** answer. If you want to know how far that actually is,

then you take some number that's approximately π and multiply it by

8 km. You can never get an exact answer like that, because you can

never write the exact value of π with digits.

In school, we often use ' 3.14 ' for π . If you do that, then the bus

traveled

(8 km) x (3.14) = 25.1 kilometers .

When you do that, you have to remember that it's approximate.

If you want an exact answer, then you have to leave π in the answer.

Well, consider the unluckiest case: In whatever order, you manage to remove nine of the red marbles, nine of the blue ones, nine of the green and all of the yellow and orange mix. So far, you've removed 37 of the marbles (9+9+9+10 = 37), yet you don't have 10 of any single color. If you remove just one more marble, it will be red, blue, or green, and you will have 10 of the same color. So the answer is 38 marbles. :)

we divide 2500 by the prize of a male pare of shoes, 50 dollars:

The number of miles Steve ran is:

** 4 miles.**

Steve uses an app that shows him how many kilometers he has run to prepare for a marathon.

The app said he ran 6.436 kilometers.

Now, we will use the conversion to find the number of kilometers in miles.

The conversion is:

1 mile = 1.609 kilometers

i.e. 1 kilometers= 1/1.609 miles.

Hence,

6.436 kilometers= 6.436/1.609 miles

**i.e. 6.436 kilometers= 4 miles.**

Let x = the ones digit

Let y = the tens digit

x+2y=12

x=2y

x+y=12 substitute x for 2y to get:

(2y)+y=12 add like terms to get:

3y=12

3y=12 divide both sides by 3 to get:

y=4

x+y=12 substitute y for 4 to get:

x+4=12 subtract 4 from both sides to get:

x=8

so if x=ones

and y=tens

A^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse

90^2 + 120^2 = c^2

8100 + 14400 = c^2

22500 = c^2.....take the sq rt of both sides...this gets rid of the ^2

sq rt 22500 = c

150 = c

so side a = 90 ft, side b = 120 ft, and side c = 150 ft

this is called the pythagorean theorem and it only works on right triangles

QUESTION POSTED AT 28/01/2020 - 12:08 AM

Using Descartes' Rule of Signs, we observe whether each consecutive term has a + or - sign:

f(x) = 3x4 − 5x3 − x2 − 8x + 4

Signs are: + - - - +

There are 2 sign changes (from +3 to -5, then from -8 to +4). This means that there are either 2 or 0 positive roots. (We take the number of sign changes, which is 2, and subtract by 2s to get all possible numbers of positive roots.)

For negative roots, we first invert all the odd-powered terms in f(x):

3x4 + 5x3 − x2 + 8x + 4

Signs are: + + - + +

There are 2 sign changes, from +5 to -1, and from -1 to +8. Therefore, there are either 2 or 0 negative roots.

Since the overall degree of f(x) is 4, the total number of roots must sum up to 4. There are either 2 or 0 positive roots, and 2 or 0 negative roots, and everything that remains will be a complex root. The possibilities are:

2 positive, 2 negative, 0 complex

2 positive, 0 negative, 2 complex

0 positive, 2 negative, 2 complex

0 positive, 0 negative, 4 complex.

Therefore we can have either 0, 2, or 4 complex roots.

The correct answer is the last choice.
