Answer:

1 11/12

Step-by-step explanation:

rewriting our equation with parts separated

=1+14+23

Solving the fraction parts

14+23=?

Find the LCD of 1/4 and 2/3 and rewrite to solve with the equivalent fractions.

LCD = 12

312+812=1112

Combining the whole and fraction parts

1+1112=11112

Solution by Formulas

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

54+23

Applying the fractions formula for addition,

=(5×3)+(2×4)4×3

=15+812

=2312

Simplifying 23/12, the answer is

=1 11/12

Answer:

1 11/12

Step-by-step explanation:

add wholes = 1

then fractions 1/4 = 3/12      2/3=8/12

this then equals 1 11/12

Answer:

- 8°

Step-by-step explanation:

Step 1:

40° + x + 58° + 90° = 180°       Sum of a Δ

Step 2:

188° + x = 180°       Combine Like Terms

Step 3:

x = 180° - 188°     Subtract 188 on both sides

Answer:

x = - 8°

Answer: 12(a+5)

Step-by-step explanation: factor out 12 from the expression

ANSWER 12(a+5)

Answer: 18+0.08B>75

Step-by-step explanation: 713 paintballs

The inequality equation is given as 18 + 0.08B ≥ 75 then the number of the paintballs that Carolina buys is 713.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.

Carolina goes to a paintball field that charges an entrance fee of \$18 and $0.08, per ball.

The field has a promotion that says, "Get $10 off if you spend $75 or more!" Carolina wonders how many paintballs she needs to buy along with the entrance fee to get the promotion.

Let B represent the number of paintballs that Carolina buys.

Then the inequality equation will be given as

18 + 0.08B ≥ 75

Then the value of B will be

0.08B ≥ 75 - 18

       B ≥ 712.5 ≈ 713

Step-by-step explanation:

Kindly find attached a detailed image to better understand the solution to this problem.

given that the total length of the line is 720ft

and also the line is divided into three sections

This means that the line will also be divided into three parts

720/3= 240feet so that a section will have two sides that are 240ft since the section forms a rectangular shape.

now for the other two sides

the total length of the rope is  = one length size of the rectangle+ 4 width size of the rectangle

one width size of the rope is x

then 4 width size is 4x

720=length of rectangle +4x

length of rectangle= 720-4x

area of a rectangle is =length *width

area of rectangle is =  (720-4x)*x

Hence the function A=  (720-4x)x can be used to solve for the area of the rectangle.

Answer:

-22

Step-by-step explanation:

y=6x+(x-1)    original equation

y=6(-3) +(-3-1)   substitute x value

y= -18 + -4       simplify

y=-18-4        solve

y=-22

Answer:

24 days is the answer

Step-by-step explanation:

If the book is 240 pages and each day 10 pages are read you could easily divide 240 by 10 and get 24.   However, you need to use the formulas for your answer I suppose.  So, to get the  x-intercept this is what you do.  You have to use the slope-intercept form y = mx+b  where m=-10 and b = 240 so you end up with y = -10x+240

So now you solve for x-intercept

0 = -10d+240

subtract 240 from both sides so       0 = -10d + 240

                                                         -240              -240

you are left with -240 = -10d.  Now simplify and divide each term by -10     -240/-10 = 24 and -10d/-10 = d

   you are left with d = 24 or 24 = d

You graph the equation by placing a point at  240 on the y axis and 24 on your X-axis.

Answer:

she can spend no more than 64, and if this is incorrect, do 63

Step-by-step explanation:

Given:

Total number of questions = 6

Choice for each question (in MCQ) = 4

Assuming that no questions are left unanswered.

To find:

The total number ways to answer the quiz, assuming that no questions are left unanswered.

Solution:

Here, Number of ways to answer each question = 4

To find the  total number ways to answer 6 MCQ, we have to have to multiply number of ways to answer each question 6 times.

Total number of ways to answer six-question quiz with 4-choice multiple choice questions is

[tex]4\times 4\times 4\times 4\times 4\times 4=4096[/tex]

Therefore, the required number of ways is 4096.

There are 4096 ways to answer the six-question quiz with 4-choice multiple-choice questions.

We have,

For each question on the quiz, there are 4 choices.

Since each question is independent of the others, the total number of ways to answer the entire quiz can be found by multiplying the number of choices for each question together.

There are 6 questions with 4 choices each.

4 choices for the 1st question * 4 choices for the 2nd question * 4 choices for the 3rd question * 4 choices for the 4th question * 4 choices for the 5th question * 4 choices for the 6th question

= [tex]4^6[/tex]

Using exponential notation,

[tex]4^6[/tex] = 4 * 4 * 4 * 4 * 4 * 4 = 4096

Therefore,

There are 4096 ways to answer the six-question quiz with 4-choice multiple-choice questions.
