Answers

Answer 1

Answer:

D: x = -18

Step-by-step explanation:

A good way to solve this it to input all options until you find the one that fits for both options.

Option A :

15 + 6 / 15 - 3 = 21 / 12 or 7/4

So this one doesn't work.

Option B :

10 + 6 / 10 - 3 = 16 / 7

So this one also doesn't work.

Option C:

3 + 6 / 3 - 3 = 9 / 0 which is 0 by the laws of dividing by zero.

This one also doesn't work leaving only one option.

Option D:

-18 + 6 / -18 - 3 = -12 / -21 or 4 / 7

And by solving we can find out we did our work correctly and get our answer.

The secants form a proportion where the full length of the secant is the denominator of a fraction where the numerator is the external part of the secant.

7/(x + 7) = 6/(15 + 6)         Cross Multiply after combining

7 / (x + 7) = 6/(21)                

6 * (x + 7) = 7 * 21             Remove the brackets

6x + 42 = 147                   Subtract 42

We can see:

x- values increase by 1 unity- values decrease by 3 units (slope is -3).

This is a linear relationship. Use point-slope form to find the equation:

Joyce had business cards made through a printing company. They charge an initial fee of $12 and $3.99 for each box of 100 business cards. If Joyce needs 5 boxes, how much will she be charged?
A. $31.95
B. $52.88
C. $119.95
D. $63.99

Answers

Answer:

The correct choice is option A. $31.95

Step-by-step explanation:

The total cost would be the basic fee + the price of the boxes.

So, the initial fee is $12, Joyce needs 5 boxes, and $3.99 is charged per box.

$12 + 5 × $3.99 = 31.95

Dylan is driving to a concert and needs to pay for parking. There is an automatic fee
of $5 just to enter the parking lot, and when he leaves the lot, he will have to pay an
additional s2 for every hour he had his car in the lot. How much total money would
Dylan have to pay for parking if he left his car in the lot for 6 hours? How much
would Dylan have to pay if he left his car in the lot for t hours?

Answers

Answer:

17

Step-by-step explanation:

6 x 2 = 12 so 12 + 5 = 17

Dylan would have to pay $17.

Dylan would have to pay $17 if he left his car for 6 hours. Dylan would pay 5 + 2t if he left his car for t hours.

For such questions it is best to form an expression.

The parking fee has a fixed cost of $5.

It also has a cost per hour of $2.

This means that if a person spends t hours at the parking lot, they will have to pay $2 per hour for those t hours.

Expression = 2 x t = 2t

Whole expression including the fixed amount is:

5 + 2t

If Dylan parked for 6 hours therefore, he would pay:

= 5 + 2 t

= 5 + 2 x 6

= $17

Dylan would therefore have to pay $17 if he left his car for 6 hours.

Answer:

Length = 42 mPerimeter = 168 m

Concept:

Here, we need to know how to find the area and perimeter of the square.

Area (square) = s²

s = side length

Perimeter (square) = 4s

s = side length

Solve:

PART I: Find the length

Given information

Area = 1764 m²

Given formula

A = s²

Substitute values into the formula

1764 = s²

Square root both sides

√s² = √1764

[tex]\boxed{s=42m}[/tex]

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

PART II: Find the perimeter

Given information

s = 42 m

Given formula

P = 4s

Substitute values into the formula

P = 4 (42)

Simplify by multiplication

[tex]\boxed{P=168m}[/tex]

Step-by-step explanation:

6 choose 3 = 20

The total combinations of fruit he can bring is 20 if Bill has an apple, an orange, a pear, a grapefruit, a banana, and a kiwi at home and he wants to bring three pieces of fruit to school the answer is 20.

What are permutation and combination?

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have:

Bill has an apple, an orange, a pear, a grapefruit, a banana, and a kiwi at home and he wants to bring three pieces of fruit to school

Total number of fruits = 1+1+1+1+1+1

Total number of fruits = 6

n = 6

He wants to bring three pieces of fruit to school,

r = 3

Total combination:

= C(6, 3)

= 6!/(6-3)!3!

= 720/(6)(6)

= 720/36

= 20 combination

Thus, the total combinations of fruit he can bring is 20 if Bill has an apple, an orange, a pear, a grapefruit, a banana, and a kiwi at home and he wants to bring three pieces of fruit to school the answer is 20.

What is the measure of the angle if an angle if it is 300 less than five times its own supplement

Angle = _______ degrees

Answers

Answer:

100°

Step-by-step explanation:

Let the angle = x

Its supplement = 180 -x

5*(180 - x ) - x = 300    

5*180 - 5*x - x= 300    {Distributive property}

900 - 5x  - x = 300     {Combine like terms}

900 - 6x  = 300         {Subtract 900 from both sides}

       -6x = 300 - 900

      -6x = -600           {Divide both sides by (-6)}

          x = -600/-6

        x = 100

The sum of square root 5 and 2 square root 16 in simplest form is, √5 + 8 and it is irrational number

What is square root?

In mathematics, square roots is a concept in which, if we multiply square roots of any number by itself then it will give us an original number.

if 'a' is square root of 'b' then it will represent as, a = √b.

Given that,

the maximum possible simplest form is √5 + 8

As it is clear that, it is a irrational number

Because, √5 can not be written in P/Q form

Hence, the sum is √5 + 8
