Answer:

2 9/14

Step-by-step explanation:

first we must make 1/6 and 3/7 have common demoniaters! (or however u spell it)

1/6 x 7/7 = 7/42

3/7 x 6/6 = 18/42

7/42 + 18/42 = 25/42

2/7 x 6/6 = 12/42

25/42 + 12/42 = 37/42

37/42 + 7/42 = 44/42

44/42 + 18/42 = 62/42

62/42 + 12/42 = 74/42

5/7 x 6/6 = 30/42

74/42 + 30/42 = 104/42

104/42+7/42 = 111/42

111/42 = 2 9/14

From the previous question we know that:

Answer:

y=2x-14

Step-by-step explanation:

y=mx+b(m is slope)

we know

y=2x+b

so if you plug in the values for the points you get

-6=4(2)+b

-6=8+b

b=-14

so then the complete equation would be

y=2x-14

Answer:

Step-by-step explanation:

A "greater than or equal to" sign means that your line will have a closed, or filled in circle. Knowing this, we can eliminate all of the open circle options.

If our numbers are negative, a number "greater than" a negative would be closer to or positive. I would choose the filled in circle pointing towards the right, given this information.

And for solving the inequality:

-3x (greater than or equal to) -18

Answer:

36 non repeating, 72 repeating (AB=BA)

Step-by-step explanation:

There is a theoretical approach to solving this question. We have formulae for such types of question in ‘Permutation and Combination’ chapter but let me solve it through my approach.

There are 9 members in the unit.

we have to choose only 2 people out of them randomly.

let the members be A, B, C, D, E, F, G, H an, I

A can be chosen first with one of the rest as the second person.

Like AB, AC, AD, AE … AI ………………………(1)

by this, we can choose people in 8 ways.

we will also have 8 ways as BA, CA, DA, … IA ………..(2)

the series (2) is completely reverse of series (1)

now perform the same action taking B as first-person and people after B as the second person.

by this, we will have 7 ways

and 7 ways again in reverse mode.

The same process with C, D, E and other members

we get

8*2 = 16 ways with A

7*2 = 14 ways with B

6*2 = 12 ways with C

5*2 = 10 ways with D

4*2 = 8 ways with E

3*2 = 6 ways with F

2*2 = 4 ways with G

1*2 = 2 ways with H

and I can not be selected lonely because there is no person after I.

SO total ways = 16 + 14 +12 + 10 + 8 + 6 + 4 + 2 = 72 ways

72 will be the answer if the selection of A first and B second is different from the selection of B first and A second.

If AB = BA then the answer will be 72/2 = 36

(It is my approach and easier way for me than the traditional formulae)

Answer:

Step-by-step explanation:

You've omitted A and D.

Find the points of intersection.

y = 3x-6 and y = -2x+8 intersect at (2.8,2.4)

B:

The y-axis and y = 3x-6 intersect at (0,-6).

The y-axis and y = -2x+8 intersect at (0,8)

You have a triangle with base = 14 and height = 2.8

Area = 19.6 sq units

C:

y=6 and y = 3x-6 intersect at (4,6)

y=6 and y = -2x+8 intersect at (1,6)

You have a triangle with base = 3 and height = 6-2.4 = 3.6

area = 5.4 sq units

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of campers who voted for hot dogs = 5 campers

Let the number of campers who voted for sphagetti = 4 campers

Now , the total campers = 5 + 4

                                        = 9 campers

5 out of 9 campers vote for hot dogs

So ,

The total number of campers = 72 campers

The equation will be ,

The total number of campers who voted for hotdogs =
( number of campers who voted for hot dogs / the total campers ) x 72

The total number of campers who voted for hotdogs = ( 5 / 9 ) x 72

                                                                                        = 5 x 8

The total number of campers who voted for hotdogs = 40 campers

Hence , The number of campers who voted for hotdogs is 40 campers

Answer:

(28000,40000)      or     $28,000 to $40,000

Step-by-step explanation:

plug in values as V and solve for x:

12,000=22,000-0.25x

-10,000=-0.25x

40,000=x

15,000=22,000-0.25x

-7,000=-0.25x

28,000=x

an interval notation always has the lower value first so its:

(28000,40000) or $28,000 to $40,000

Answer:

about 5 years 6 months

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

t = 178.25 / ( 650 × 0.05 ) = 5.4846

t = 5.4846 years

The time required to

accumulate simple interest of $ 178.25

from a principal of $ 650.00

at an interest rate of 5% per year

is 5.4846 years (about 5 years 6 months).

Answer:

2√3

Step-by-step explanation:

In a special right triangle called the 30-60-90 triangle, the ratios of the side lengths are x-x√3- 2x respectively. This means that the side opposite to the 60 degrees is x√3 and the side opposite to the 30 degrees is x.

Since the side opposite to the 60 degrees is 6, x√3=6

x√3=6

x=6/√3

rationalize the denominator:

6√3/3

simlify

2√3

so the answer is the third one. 2√3

Answer:

You begin with 1 bacteria, and after 1 hour it has tripled so you now have 1 x 3=3.

Next hour, it triples again so you now have 1 x 3 x 3=9

You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 34 means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).

Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:

n x 324 where n is the number of bacteria you begin with.

Since you begin with 1 bacteria, the solution is 1 x 3 to the power 24 and u will get ur answer
