Answer:

54.2%

Step-by-step explanation:

The total number is 238 + 201 = 439.  The percent that is Republican is:

238 / 439 × 100% = 54.2%

The percentage of Republicans in the House of Representatives in 2018 was approximately 54.21%, computed using the formula for percentage calculation - (number of Republicans/total number of representatives)*100.

The subject of this question is Mathematics, specifically Percentage Calculation. To answer the question, we need to find the percentage of Republicans in the House of Representatives in 2018. Given that there were 238 Republicans and 201 Democrats, the total number of representatives is 238 + 201 = 439.

To find the percentage of Republicans, we divide the number of Republicans by the total number of representatives and multiply by 100. So, the calculation would be: (238/439) * 100, which gives approximately 54.21%. Therefore, the percentage of Republicans in the House of Representatives in 2018 was approximately 54.21%.

The data we have is:

They charge $40 per hour.

In january, the charged for 200 hours.

The expenses are:

rent $4000

electricity $325

Nice! Uhh... What am I supposed to do with this info?

Answer:

The correct answer is that the probability of a randomly selected adult has an IQ less than 145 is 97.8%

Step-by-step explanation:

According to the graphic of a standard distribution attached, we have:

68.3% of the population will have an IQ +/- one time the standard deviation plus the mean. It means that 68.3% (Rounding to one decimal place) of the adults will have an IQ between 85 and 125.

95.5% of the population will have an IQ +/- two times the standard deviation plus the mean. It means that 95.5% (Rounding to one decimal place) of the adults will have an IQ between 65 and 145.

The remaining 4.5% of the adults will have either an IQ below 65 or above 145. In this case, we only want to know the percentage below 65 because the question is about the probability of an IQ less than 145. For calculating the percentage of adults that have an IQ less than 65, we use this fraction:

4.5%/2 = 2.3% (Rounding to one decimal)

and we add this percentage to 95.5:

Probability that a randomly selected adult has an IQ less than 145 = 95.5 + 2.3 = 97.8%

Answer:

50 gallos of 70%

100 gallons of 85%

Step-by-step explanation:

x = amount of 70% antifreeze

y = amount of 85% antifreeze 

   EQUATION 1:   x + y = 150    (total of 150 gallons mixed) 

   EQUATION 2:  .70x + .85y = .80(x + y)

    Multiply second equation by 100 on both sides to remove the decimals           70x + 85y = 80(x + y)  

  70x + 85y = 80x + 80y   (distributive)     

  70x - 80x + 85y - 80y = 0          

 -10x + 5y = 0      

Now we have the following system of equations:        

     x  +  y = 150     

  -10x +5 y = 0  

 Multiply the first equation by 10 to get opposite coefficients for x;  add the equations to eliminate x        

  10x + 10y = 1500       

 -10x + 5y =       0     

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

                15y = 1500    

 Solve for y            15y = 1500                y = 100

x+100=150    x=50

Answer:

B)     b = 240 - 5 x is the required expression to decipher the situation.

Step-by-step explanation:

The amount paid to the club in the advance = $240

Amount deducted in each visit = $5

Let us assume the number of times the club visited = x

So, the amount deducted in x visits  = x ( $5)  = 5x

Let b : amount Left after x visits

So, Amount left after x visits  = Advance Amount - Deductions after x visits

⇒  b = $240 - 5x

or , b = 240 - 5x is the required expression to decipher the situation.

Answer:

Giselle pays $240 on advance

Each time she uses ,$5 is deducted

Let no of time she use be x

So, Amount deducted = 5x

As Giselle pays $240 in advance

So 5x amount will be deducted from $240 to get net amount

So b= 240-5x

B) is Correct

The value of 'n' in the given mathematical equation n/256 = 8 1/3 * 8 1/3 is approximately 17766.4.

The question asks what is the value of n if n divided by 256 = 8 1/3 times 8 1/3. To find the answer, first we need to calculate the value of 8 1/3 times 8 1/3. Converting 8 1/3 to a decimal result in approximately 8.33. Then, we multiply 8.33 by itself to get approximately 69.4.

Since n divided by 256 gives this value, to find n, we simply multiply 69.4 by 256. This results in approximately 17766.4. Therefore, given the condition in the problem, the value of n would be approximately 17766.4.

To find the value of n, we need to solve the equation: n/256 = 8 1/3 * 8 1/3. First, let's convert 8 1/3 to a fraction: 8 1/3 = 25/3. Next, multiply 25/3 by itself to get (25/3) * (25/3) = 625/9. Now we can solve for n by multiplying both sides of the equation by 256: n = (256 * 625/9).

Answer:

Step-by-step explanation:

$1331 is invested at 7% and $5566 is invested at 6%

Step-by-step explanation:

The formula of the simple interest is I = P r t, where

Assume that Sherry invested $P in the first account

∵ Sherry invested $P in the first account at 7% interest for 1 year

∵ I = P r t

∴ The interest of the 1st account = P( [tex]\frac{7}{100}[/tex] )(1)

∴ The interest of the 1st account = 0.07 P

∵ Sherry also invested $242 more than four times that amount at

   6% for 1 year

- Multiply P by 4 and add 242 to the product

∴ Sherry invested in the 2nd account (4P + 242)

∵ I = P r t

∴ The interest of the 2nd account = (4P + 242)( [tex]\frac{6}{100}[/tex] )(1)

∴ The interest of the 2nd account = 0.06(4P + 242)

- Simplify it

∴ The interest of the 2nd account = 0.24 P + 14.52

∵ Sherry receives $427.13 in interest after one year

- Equate the 1st interest and the 2nd interest and equate the sum

  by 427.13

∴ 0.07 P + 0.24 P + 14.52 = 427.13

∴ 0.31 P + 14.52 = 427.13

- Subtract 14.52 from both sides

∴ 0.31 P = 412.61

- Divide both sides by 0.31

∴ P = 1331

∵ She invested (4P + 242) in the 2nd account

- Substitute P by 1331

∴ She invested in the 2nd account = 4(1331) + 242 = 5566

∴ She invested $1331 at 7% interest

∴ She invested $5566 at 6% interest

$1331 is invested at 7% and $5566 is invested at 6%

Step-by-step explanation:

Given: The value of 0.035

Now, as we know 0.035 has three decimal place which mean if we multiply by 1000 then we have the product 35 which is greater than 1 and less than 100, however if we multiply 0.035 by 10000 then the output will be greater than 100, which is invalid.

Lets us use hit and trail method.

Answer:

65 bikes

Step-by-step explanation:

The store buys the bikes that they sell for $35, and they sell them for $85, so in order to find the actual amount of money earned from one sale, you have to subtract how much they sell the bikes for by how much they bought them for, so:

85 - 35 = 50

Then, you divide the $3250 by the 50:

3250 / 50 = 65

So now we know that the store must sell 65 bikes a month to break even.

To find the number, subtract 37 from both sides of the equation and isolate 'x'. The number is 54.

To find the number, let's represent it with the variable 'x'. The problem states that when 17 is added to the number, the result is 37 less than twice the number.

Mathematically, this can be represented as:

x + 17 = 2x - 37

To solve for 'x', we can start by subtracting 'x' from both sides of the equation:

17 = x - 37

Next, we can add 37 to both sides to isolate 'x':

54 = x

Therefore, the number is 54.

Answer: 16 m

Answer: [tex]300\ Kg[/tex]

Step-by-step explanation:

Let be "x" the amount of butter (in kilograms) that the bakery used this month.

You need to divide the percentage by 100 in order to write it in decimal form. This is:

[tex]\frac{25}{100}=0.25[/tex]

According to the data given in the exercise, the total amount of butter they used last month is 240 kilograms.

Since 25% more butter was used this month than last month, you can write the folllowing equation:

[tex]x=240+(240 )(0.25)[/tex]

Evaluating, you get that the value of "x" is:

[tex]x=240+60\\\\x=300[/tex]

Therefore, the bakery used 300 kilograms of butter this month.

Final answer:

The bakery used 300 kg butter this month.

Explanation:

If a bakery used 25% more butter this month than last month and it used 240 kg of butter last month, then to calculate the amount of butter used this month, we need to add an additional 25% to the amount from last month. To find 25% of 240 kg, you multiply 240 kg by 0.25 (since 25% is the same as 0.25 when expressed as a decimal).

25% of 240 kg = 240 kg × 0.25 = 60 kg

Now, we add that 60 kg to the original 240 kg to find the total amount of butter used this month.

Total amount of butter used this month = 240 kg + 60 kg = 300 kg.

Therefore, the bakery used 300 kg of butter this month.
