Answers

Answer:

0.32 repeating as a fraction

= 32/99

Step-by-step explanation:

The fraction in simplest form that represents the repeating decimal 0.32 repeating is 32/99.

To express the repeating decimal 0.32 repeating as a fraction in simplest form, we can use the concept of geometric series.

Let's represent 0.32 repeating as x:

x = 0.323232...

Multiply both sides of the equation by 100 to shift the decimal point two places to the right:

100x = 32.323232...

Now, subtract the original equation from the shifted equation to eliminate the repeating part:

100x - x = 32.323232... - 0.323232...

Simplifying the equation:

99x = 32

Divide both sides of the equation by 99 to solve for x:

x = 32/99

Therefore, the fraction in simplest form that represents the repeating decimal 0.32 repeating is 32/99.

In the last student-council elections, Jill got x number of votes. Morgan got twice as many votes as Jill. Trisha won the election with 7 more votes than Morgan. If 327 students voted in the election, write and solve an equation to determine how many votes Trisha got.

Answers

Answer:

the equation is x + 2x + 2x + 7 = 327

or 5x + 7 = 327

x = 64

Trisha has 135 votes.

Step-by-step explanation:

Jill has x votes.

If Morgan got twice as many votes as Jill, then Morgan has

2 times the number of votes

or 2x

Trisha won the election with 7 more votes than Morgan's, so we add 7 to this amount

2x + 7

So assuming Jill, Morgan, and Trisha are the only three candidates:

then x + 2x + 2x + 7 = 327

Combine like terms

5x + 7 = 327

Subtract 7 from both sides

5x = 320

x = 64

Check answer for x:

64 + 2(64) + 2(64) + 7 = 64 + 128 + 128 + 7 = 327

So Trisha has

2x + 7 = 2(64) + 7 = 128 + 7 = 135 votes

From step 1 to step 2 they distributed the 2 (multiplied the inner numbers of the parentheses)
From step 2 to step 3 they added 6x to both sides,canceling out the -6x on the left side and adding 6x with the 5x
From step 3 to step 4 they subtracted 2 from both sides, canceling it out on the right side and subtracting 2 from 8 to get 6
From step 4 to step 5 they try and get x alone by dividing both sides by 11, canceling out the 11 on the right side and leaving a fraction the left
Leaving you with your answer of what x equals in the final step

Answer:

a)

f(0) = 4, from the graph

b)

h(11) = 15, from the table

c)

g(-9) = -2(-9)² - 4(-9) + 1 = -125, as per equation

d)

f(2) = 1, from the graph

e)

h(-2) = 2, from the table

f)

g(0.25) = -2(0.25)² - 4(0.25) + 1 = - 0.125, as per equation

f(0) = 4

h(11) = 15

 

g(-9) = -2(-9)² - 4(-9) + 1 = -125

f(2) = 1

h(-2) = 2  

g(0.25) = -2(0.25)² - 4(0.25) + 1 = - 0.125

Answer: 2.3/225.4=0.01020408

Answer:

98.000

Step-by-step explanation:

Change the divisor 2.3 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

2254 ÷ 23 = 98.000

Answer:

D because it costs less for 7 hours

Answer:

The company that would give you the best deal would be Company D.

Step-by-step explanation:

Company A:

First you set up as an equation.

y=25x+50

I used 25x because 25 represents the hourly rate and x represents the hour it increases.

y=25(7)+50

We have to substitute 7 in for x because it says "If you had planned for 7 hours".

Multiply 25 and 7. You should get 175.

y=175+50

Add 175 and 50. You should get 225.

y=225.

You do the same thing for the rest of the problems.

Company B:

y=30x+40

y=30(7)+40

y=210+40

y=250

Company C:

y=20x+60

y=20(7)+60

y=140+60

y=200

Company D:

y=5x+150

y=5(7)+150

y=35+150

y=180

The company that would give you the best deal would be Company D.

Hakim and Aziz had some savings in the ratio 3 : 5. Hakim saved another $82 and Aziz spent $110. Both have the same amount of money now. How much do each of them have now?​

Answers

Answer:  $370

===========================================================

Explanation:

Hakim and Aziz have savings in the ratio 3:5. This means that Hakim has 3x dollars while Aziz has 5x dollars. The x is some positive real number.

We're then told that Hakim saved another $82, which means it goes from 3x to 3x+82

At the same time, Aziz spent $110 which means the 5x decreases to 5x-110

At this point, the two people have the same amount of money. Set the expressions we found equal to one another and solve for x.

3x+82 = 5x-110

3x-5x = -110-82

-2x = -192

x = -192/(-2)

x = 96

Then use this x value to compute each expression like so

3x+82 = 3*96+82 = 3705x-110 = 5*96-110 = 370

Both have $370 after Hakim saved that additional $82 and after Aziz spent that $110.

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

Extra info:

If we rewind things a bit, Hakim would have 3*x = 3*96 = 288 dollars while Aziz would have 5x = 5*96 = 480 dollars. This is before any additional saving or spending.

Then note how the ratio 288:480 fully reduces to 3:5 after dividing both parts by the GCF 96.

Answer:

Step-by-step explanation:

(-5)(-5)(-5)=-125

Given the expression:

[tex] \displaystyle \large{ \sqrt[3]{ - 125} }[/tex]

Definition:

[tex] \displaystyle \large{ y = \begin{cases} \pm \sqrt[n]{x} \longrightarrow n = (2,4,6,8,...) \: \: (x \geqslant 0) \\ \sqrt[n]{x}\longrightarrow n = (1,3,5,7,...) \: \: (x \in \R) \end{cases}}[/tex]

First, factor the -125. -125 comes from (-5)×(-5)×(-5) or (-5)^3.

[tex] \displaystyle \large{ \sqrt[3]{ ( - 5) \times ( - 5) \times ( - 5)} }[/tex]

Because if (-5)^2 = 25 then 25×(-5) again will be -125.

Since this is the cube root, we have to pull out 3 terms in one. There are 3 fives that we can take off and therefore,
