what value of x makes the equation 3(x - 6) - 8x = -2 + 5(2x + 1) true ?

Answers

Answer:

x = -3

Step-by-step explanation:

3(x - 6)= -2 + 5(2x + 1)

= 3x - 18 = -2 + 10x + 5

= -18 = -2 + 7x + 5

= -18 = 7x + 3

= -21 = 7x

= -3 = x

Angie and Eric have opened a jumbo bag of candies and counted the number of each color. They have 100 red, 180 green, 90 yellow, and 130 brown candies. Sarah and Laney each take turns drawing a candy, replacing each candy after they draw. If Angie and Eric each draw a candy 500 times, how many times should they expect for Angie to draw a brown candy followed by Eric drawing a red candy?

Answers

Answer:

26 times.

Step-by-step explanation:

Total number of candies = 500.

Probability ( Angie drawing a brown candy) = 130/500  = 13/50.

Probability (Eric drawing a red candy) = 100/500 = 1/5.

So Probability ( Angie drawing brown then Eric drawing a red) = 13/50 * 1/5

= 13/250.

Therefore the expectation  of the number of times this will happen

= Probability * total number of draws

=  (13/250) * 500

= 13 * 2

=  26 times.

Darnell starts the month $952.43 in his checking account. Darnell buys an iPhone 7 for $217.49 with tax included, and two kindle books that each cost $7.99. He pays with his checking account debit card. What is his new balance? The new iPhone 7 is not as awesome as promised, and Darnell returns it. What is his new balance? Explain how returning the phone is like the subtracting a negative number from his balance.

Answers

Answer:

Therefore his new balance=$712.95

Therefore his new balance is  =$ 930.44  

Step-by-step explanation:

Darnell starts the month $ 952.43 in his checking account.

He buys an iPhone 7 for $ 217.49 with tax included and two kindle books that each $7.99.

The price of two books is =$(7.99× 2)= $ 15.98

Total amount that he paid for iPhone 7 and two books is =$(217.49+15.98)

                                                                                              =$233.47

Therefore his new balance = $(952.43- 233.47)

                                            =$712.95

The new iPhone 7 is not as awesome as promised , and Darnell returns it.

He will get the price of iPhone refund.

Therefore his new balance is $(712.95+217.49)

                                                =$ 930.44            

Darnell's new balance after purchases is $718.96. When he returns the iPhone 7, his balance is back to $936.45, as subtracting the negative cost of the iPhone is equivalent to adding its price back to his account.

To find Darnell's new balance after his purchases and subsequent return, we need to perform a few calculations based on the transactions. Darnell starts with $952.43 in his checking account. First, he purchases an iPhone 7 for $217.49 and two Kindle books, each costing $7.99. The total cost for the books is $7.99 x 2 = $15.98. We subtract these amounts from his initial balance:

$952.43 - $217.49 = $734.94

$734.94 - $15.98 = $718.96

Therefore, after the purchases, Darnell's new balance is $718.96.

When Darnell returns the iPhone 7, he gets a refund of $217.49, which is like subtracting a negative number from his balance because subtracting a negative is the same as adding a positive. So:

$718.96 + $217.49 = $936.45

After returning the iPhone 7, Darnell's new balance is $936.45.

What is the solution to the equation?

Answers

Answer:

x= 27

Step-by-step explanation:

Move constant to the right-hand side and change its sign.

[tex]\sqrt{2x+10}[/tex] = 2+6

Add the numbers.

[tex]\sqrt{2x+10}[/tex]= 8

Square both sides of the equation.

The height h in feet of a ball thrown vertically upward from the top of a 288-foot tall building is given by h=288+48t-16t^2 where t is in seconds. How long will it take to he penny to strike the ground.

Answers

6 sec can take penny to strike the ground.

Solution:

Given data:

[tex]H_0=288[/tex] feet

[tex]V_0=48[/tex] feet

[tex]h(t)=288+48t-16t^2[/tex]

Re-arrange the terms from greatest degree to smallest degree.

[tex]h(t)=-16t^2+48t+288[/tex]

We can solve it by applying quadratic formula,

[tex]$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Here a = –16, b = 48, c = 288

[tex]$t=\frac{-48\pm \sqrt{48^2-4(-16)(288)}}{2(-16)}[/tex]

[tex]$t=\frac{-48\pm \sqrt{2304+18432}}{-32}[/tex]

[tex]$t=\frac{-48\pm \sqrt{20736}}{-32}[/tex]

[tex]$t=\frac{-48\pm144}{-32}[/tex]

Now, write find two t's using plus and minus operation.

[tex]$t=\frac{-48+144}{-32},\ \ t=\frac{-48-144}{-32}[/tex]

[tex]$t=\frac{96}{-32},\ \ t=\frac{-192}{-32}[/tex]

t = –3 (or)   t = 6

We cannot write time is negative. so neglect t = –3.

Therefore t = 6.

To find the percent of data that is at most two or three, locate the corresponding column in the frequency table and divide the frequency by the total number of data points. To find the percent of data that is more than two, subtract the percent at most two from 100.

Explanation:

1. To find the percent of data that is at most two, I would look at the table that displays the frequency of the number of movies viewed. I would locate the column that represents 'at most two' and find the corresponding frequency. To calculate the percent, I would divide this frequency by the total number of data points and multiply by 100.

2. To find the percent of data that is at most three, I would use the same procedure as in the previous question, but this time I would find the column representing 'at most three.'

3. To find the percent of data that is more than two, I would subtract the percent of data that is at most two from 100. This is because the percent of data that is at most two includes any data that is less than or equal to two.

Kittens weigh about 100 grams when born and gain 7 to 15 grams per day. If a kitten weighed 100 grams at birth and gained 8 grams per day, in how many days will the kitten triple its weight

Answers

25 days

First, start with an equation

100+8x= kittens weight

(X representing the days)

Since you’re trying to figure out the number of days it takes the kitten to triple it’s weigh you multiply it’s initial weight by 3 (100•3)

Then, you output 300 into the equation and solve

A kitten weighing 100 grams at birth and gaining 8 grams per day will take 25 days to triple its birth weight and reach 300 grams.

To calculate the number of days it will take for a kitten to triple its birth weight, we will use the given rate of weight gain and the initial weight. A kitten weighs about 100 grams at birth and gains 8 grams per day. To triple the kitten's weight, it must reach 300 grams (100 grams multiplied by 3).

First, we find the total weight gain needed for the kitten to triple its weight:

300 grams (desired weight) - 100 grams (birth weight) = 200 grams (weight gain needed).

Next, we divide the total weight gain needed by the daily weight gain to find the number of days:

200 grams (weight gain needed) / 8 grams (daily weight gain) = 25 days.

Therefore, it will take the kitten 25 days to triple its birth weight at a rate of 8 grams per day.

A person’s salary is $2500 per month. She receives a 10% raise. What is her new salary, in dollars per month?

* Write an expression using multiplication.

Answers

Answer:

Her new salary per month is $2750.

Step-by-step explanation:

Given:

A person’s salary is $2500 per month.

She receives a 10% raise.

Now, to find the new salary.

Salary per month = $2500.

She receives raise = 10% of $2500.

Now, to get the new salary:

[tex]2500+10\%\ \times 2500[/tex]

= [tex]2500+\frac{10}{100} \times 2500[/tex]

[tex]=2500+0.10\times 2500[/tex]

[tex]=2500+250[/tex]

[tex]=2750.[/tex]

Hence, the new salary = $2750.

Therefore, her new salary per month is $2750.

The person's new salary, after receiving a 10% raise, is $2750 per month.

Step 1: Calculate the raise amount:

Raise Amount = Original Salary × Raise Percentage

Raise Amount = $2500 × 0.10 = $250

Step 2: Add the raise amount to the original salary:

To determine the new salary, add the raise amount to the original salary.

New Salary = Original Salary + Raise Amount

New Salary = $2500 + $250 = $2750

Therefore, the person's new salary, after receiving a 10% raise, is $2750 per month.

Expression:

New Salary = Original Salary + (Original Salary × Raise Percentage)

New Salary = $2500 + ($2500 × 0.10)

New Salary = $2500 + $250

New Salary = $2750

How much pure acid is in 440 milliliters of a 19% solution

Answers

Answer:

83.6 mL

Step-by-step explanation:

Given 440 mL of 19% acid solution. This means the whole volume of this acid solution is 100%. Let x mL be the volume of pure acid in this solution.

Then

[tex]440\ mL - 100\%\\ \\x\ mL - 19\%[/tex]

Write a proportion:

[tex]\dfrac{440}{x}=\dfrac{100}{19}[/tex]

Cross multiply:

[tex]100\cdot x=440\cdot 19\\ \\x=\dfrac{440\cdot 19}{100}\\ \\x=\dfrac{8,360}{100}\\ \\x=83.60\ mL[/tex]

Final answer:

In 440 milliliters of a 19% solution, there are 83.6 milliliters of pure acid, calculated by multiplying the percentage (converted to a decimal) by the total volume of the solution.

Explanation:

To find out how much pure acid is in 440 milliliters of a 19% solution, you need to use the concept of percentage concentration in chemistry. The percentage concentration tells us how much of a substance is present in a solution compared to the total amount of the solution.

In this case, we have a 19% acid solution. This means that 19% of the solution's total volume is pure acid. To calculate the volume of pure acid, you multiply the total volume of the solution by the percentage (expressed as a decimal).

Calculation:

Convert the percentage to a decimal: 19% = 0.19

Multiply this decimal by the total volume of the solution: 0.19 × 440 mL

This gives us the volume of pure acid: 0.19 × 440 mL = 83.6 mL

So, there are 83.6 milliliters of pure acid in 440 milliliters of a 19% acid solution.
