Answer:

1. 0, 2. -1/2, 3.undefined, 4. -5/3, 5. 6, 6. -2, 7. 23/17

Step-by-step explanation:

y2 - y1 / x2 - x1

1. -18 - -18 / 15 - 6 = 0

2. 16 - 12 / 0 - 8 = -4/8 = -1/2

3. 37 - 2 / -15 - -15 is undefined (can't have 0 as denominator)

4. 30 - 20 / -5 - 1 = 10 / -6 = -5/3

5. -36 - -12 / 4 - 8 = -24 / -4 = 6

6. - 23 - -15 / 11 - 7 = -8 / 4 = -2

7. 100 - 54 / -38 - -72 = 46 / 34 = 23/17

Answer:

-0.7333333333

Step-by-step explanation:

1.4 x 2 1/3 =  3.2666667

3.266...  -  4 = . 7333...

So if you need it as a simplified mixed fraction you just have to turn 2.333333… into a fraction that would give you -2 1/3.

The reason for this is if you subtract 2 1/3 and 4 he would get -1.666666… then if you multiply that by 1.4 then you would get -2.33333333…. And then if you want to put that as a fraction you have to leave the negative two alone and turn 0.333333… into a fraction which would respectively be 1/3. Then finally you could add to the -2 and 1/3 together and then he would get your answer which is -2 1/3… hope this helps pal

what is the fraction for the right handed people

Answers

Answer:

Step-by-step explanation:

12% is equivalent to 12/100.  This reduces to 3/25.  Thus, 3/25ths of the students are left-handed.  The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths.  There are more right-handed people (22/25ths) versus left-handed people.

Yes the answer above is right. 12% of the class is left but in fraction form it is 12/100 because a whole percent is 100% so 12 out of 100 is 12% :) hope it helped

Answers

Answer:

a. Meg needs to find the part

b. Steve needs to find the percent.

Step-by-step explanation:

A. Does Meg need to find the part, the whole, or the percent.

Meg already knows the whole and the percent.

The whole is the entire number of dogs seen: 16 dogs.

The percent is 50%.

Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.

And she can do with a simple operation:

Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.

B. Does Steve need to find the part, the whole, or the percent.

He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).

Then he needs to find the percent, which he can do using the next operation:

Percent = (part / whole) × 100 = (7/35)×100 = 20%

Step-by-step explanation:

Part 1:

Meg needs to find the whole as 50% of the dogs = 5 therefore 100% equals 10 dogs.

Part 2:

Steve saw 50% out of two dogs meaning that he only saw 1 dog that is a boxer.

2/3 x 2 and 1/2 x 3

=5 4/6 3/6

Now add each fraction because it is the same denominator

4+3=7 so it is 7/6 now to make it a mixed fraction

7/6=1 1/6

5 +1=6

What is the minimum amount of time the machine must continue at its present rate to complete the hole on schedule? Select from the drop-down menus to correctly complete the statement.

Answers

Answer: 12 h ; 45 m

Step-by-step explanation:

*Important: From what I can see in this image, this appears to be a test. If this is the case, please do not cheat. In any case, here is the explanation.

What we know:

Progress has been made to 4.75Rate of digging is 3/5 mphDepth must be at least 12 1/2We need to find the minimum amount of time the machine works

How to solve:

By setting up an algebraic equation, we can solve this.

Process:

Set up equation                            4.75 + 3/5x = 12 1/2Convert                                          19/4 + 3/5x = 12 1/2

                                                                95/20 + 12/20x = 250/20

Subtract                                           -95/20                 -95/20

                                                                               12/20x= 155/20

Isolate x via division                                       /(12/20) /(12/20)+Simplify                                                          

                                                                                         x= 12 11/20

Convert                                                                    12 h 33 m

Solution: 12 ; 45

The minimum amount of time taken by the machine will be 12 hours and 55 minutes.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

An exceptional machine is utilized at a building site to dig openings. An opening is dug to a profundity of 4.75 feet when the machine hits the rock. The advancement eases back to 3/5 feet each hour of digging. The profundity of the opening should be no less than 12 ¹/₂ feet before the day's over to remain on time.

Convert the mixed fraction number into a decimal number.

12 ¹/₂ feet = 12.5 feet

Let 'x' be the time. Then the equation is given as,

(3/5)x = 12.5 - 4.75

Simplify the equation, then we have

(3/5)x = 12.5 - 4.75

(3/5)x = 7.75

x = 12.9167

x = 12 + 0.9167 x 60

x = 12 hours and 55 minutes

The base measure of time taken by the machine will be 12 hours and 55 minutes.

FOIL method

x^2+6x-27=0

Find the common numbers that multiply to 27 that will also equal 6.

(27x6) or (9x3)

the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.

then FOIL them

(x+9)(x-3)

FIRST:  x*x=x^2

OUTSIDE: x*-3=-3x

INNER: 9*x=9x

LAST: +9*-3=-27

x^2(-3x9x)-27

x^2+6x-27

now that the equation matches you solve for x.

(x+9)=0  x=-9

(x-3)=0   x=3
