Peter is reading a 193-page book. he has read three pages more than one-fourth of the number of pages he hasn't yet read. how many pages has he not yet read? 147 144 152 141

Answers

Let's call the number of pages we have read [tex]m[/tex]. To find the number of pages we have left to read, we'll need to subtract the number of pages we've read from the total number of pages in the book. Our total page count is 193, and the number of pages we've read is the unknown [tex]m[/tex], so the number of pages we haven't read can be written as [tex]193-m[/tex]. With that knowledge, let's construct the rest of our equation.

"He has read three pages more than one-fourth of the number of pages he hasn't yet read." The first key phrase here is "he has read." What this means is that the number of pages he's read, which we've named [tex]m[/tex], is equal to everything in the rest of the sentence. "Thee pages more than" means that we're going to be adding 3 to whatever the next quantity described is, which, in this case, is "one-fourth of the number of pages he hasn't yet read." We already established earlier that "the number of pages he hasn't yet read" is [tex]193-m[/tex], so one-fourth of that would be [tex] \frac{1}{4} (193-m)[/tex]. Putting everything together, we get the following equation:

[tex]m= \frac{1}{4} (193-m)+3[/tex]

To solve for [tex]m[/tex], we might first want to eliminate the fraction 1/4 by multiplying both sides of the equation by 4, obtaining

[tex]4m=193-m+12[/tex]

Solving for m, we get:

[tex]4m=193+12-m\\5m=205\\m=41[/tex]

Now that we have m, it's a simple matter to solve for [tex]193-m[/tex]:

[tex]193-41=152[/tex]

So, he has not yet read 152 pages.

what is x ⋅ x ⋅ x = ?

Answers

That would be x^3

Think of it like this:

Answers

you mus first find common denominator by multiplying bottom number to equal each other. 2*5=10 and 5*2=10. You must also multiply top number by same number used to find common denominator. Resulting in 6 & 5/10 and 6/10. next convert the 6 into a fraction, by multiplying by denominator. 6x10=60. 60+5 = 65. 65/10 and 6/10. Finally subtract and get 59/10. Also known as 5 & 9/10

The answer is: [A]: " 2 × 3 × 5 × 7 " .
________________________________________________________

210 = 70 * 3 ;

70 * 3 = 35 * 2 * 3 ;

35* 2* 3 = 7 * 5 * 2 * 3 ; which corresponds to "Answer choice: [A]." .
________________________________________________________

Answer: 2 X 3 X 5 X 7

Step-by-step explanation:

The given number to find the prime factorization =210

We know that 210 can be written as [tex]21\times10[/tex]

Also , 21 can be written as [tex]3\times7[/tex].

And 10 can be written as [tex]2\times5[/tex]

Then , the prime factorization of 210 is given by :-

[tex]210=21\times10\\\\=3\times7\times2\times5[/tex]

Hence, the prime factorization of 210= 2 X 3 X 5 X 7

If 17 is increased to 23, the increase is what percent of the original number? (this is known as the percent of change.)

Answers

23-17=6
The percentage of increase:
(6/17)*100=35.2942%

The value increase= 23-17
= 6
The percentage is for 100%
Thus, the increase divided by the original value, gives you the answer.
So, 6/23 x 100% is equal to 26.08%
If we round that answer up we get, 26.1

Answers

He needs to make $4,000 in sales in order to hit $575 so if he earns more than $4,000 in sales then he will exceed his goal. I did 575-455=120 to see how much he needs. Then I did 0.03×4=0.12. Well if you add 0's you will get 120 because the decimal will move so then I added 3 0's to get 0.03×4,000=120. Hope this helped.

3) Use sine ratio

sin (30°) = opposite-leg / hypotenuse

=> opposite-leg = hypotenuse * sin(30°)

A population of rabbits is growing exponentially. The function f(x) = 5(2)t models the number of rabbits after t months.

Based on the model, what is the growth factor for the population of rabbits?

Answers

13 months

Tell me if its right...

Answer:

The growth factor is '2'

Step-by-step explanation:

Here, the given function that represents the population of the rabbits that is increasing exponentially,

[tex]f(x)=5(2)^t----(1)[/tex]

Since, the growth factor is a multiplier that increases the value per period,

Also, in an exponential growth function,

[tex]y=ab^x[/tex]

b is called the growth factor where x is a variable,

Since, in function (1) t is a variable ( time in months )

By comparing, b = 2,

Hence, the growth factor is 2 for the given function.

I took the unit test and after this was the correct and answer. Hope this helps :))

Final answer:

To determine if △ABC is a right triangle, we can use the distance formula to calculate the lengths of the sides of the triangle. By comparing the squares of these lengths, we can determine if △ABC is a right triangle. For the given coordinates of vertex C, △ABC is not a right triangle.

Explanation:

To determine if △ABC is a right triangle, we need to check if the square of the length of the longest side is equal to the sum of the squares of the other two sides. Using the distance formula, we can find the lengths of AB and AC for each set of coordinates for vertex C. We then compare the squares of these lengths to determine if △ABC is a right triangle.

For C(0,2), the distance between A(1,-1) and C is √((0-1)^2 + (2-(-1))^2) = √(1 + 9) = √10. The distance between B(3,2) and C is √((0-3)^2 + (2-2)^2) = √(9 + 0) = 3. The longest side is AB with length √(2^2 + 3^2) = √(4 + 9) = √13. Since √13 is not equal to √10 + 3, △ABC is not a right triangle.

Following the same calculations for C(3,-1) and C(0,4), we find that △ABC is also not a right triangle for both cases. Therefore, the answer for all three sets of coordinates is Not a Right Triangle.

What are the excluded values of x for x^2-9x/x^2-7x-18

Answers

The expression is [tex] \displaystyle{\frac{x^2-9x}{x^2-7x-18} [/tex].

The excluded values are those values of x for which the denominator, [tex]x^2-7x-18[/tex], becomes zero.

So, we need to factorize the expression [tex]x^2-7x-18[/tex].

To factorize the expression, we can use the grouping method. Write -7x as -9x+2x to create 4 terms, as follows:

[tex]x^2-7x-18=(x^2-9x)+(2x-18)=x(x-9)+2(x-9)[/tex].

The, factorizing (x-9), we have (x-9)(x+2).

This expression becomes 0 for x=-2, or for x=9.

Answer: {-2, 9}

The excluded values of x for x^2-9x/x^2-7x-18 are -2 and 9

The expression is given as:

x^2-9x/x^2-7x-18

Set the denominator of the expression to 0

x^2-7x-18 = 0

Expand the above expression

x^2 + 2x -9x -18 = 0

Factorize the expression

x(x + 2) -9(x +2) = 0

Factor out x + 2

(x -9)(x +2) = 0

Solve for x

x = 9 and x = -2

Hence, the excluded values of x for x^2-9x/x^2-7x-18 are -2 and 9

Vehicle a averages 14 miles per gallon of gasoline, and vehicle b averages 36 miles per gallon of gasoline. at these rates, how many more gallons of gasoline does vehicle a need than vehicle b to make a 1,008-mile trip?

Answers

Final answer:

Vehicle A requires 72 gallons and vehicle B requires 28 gallons for a 1,008-mile trip. Therefore, vehicle A needs 44 more gallons of gasoline than vehicle B for the trip.

Explanation:

To calculate the number of gallons of gasoline each vehicle needs for the trip, we would divide the total distance of the trip by the miles per gallon (mpg) that each vehicle gets. Then, to find out how many more gallons of gasoline vehicle A needs than vehicle B, we subtract the gallons of gasoline used by vehicle B from the gallons used by vehicle A.

First, we find the gallons needed for vehicle A:

Vehicle A: 1,008 miles ÷ 14 mpg = 72 gallons

Next, we calculate the gallons needed for vehicle B:

Vehicle B: 1,008 miles ÷ 36 mpg = 28 gallons

Finally, we determine how many more gallons vehicle A requires than vehicle B:

Additional gallons needed by vehicle A: 72 gallons - 28 gallons = 44 gallons

Jon makes $78 in 12 hours of work for his mom. how much would jon make in 20 hours of work

Answers

$ 78 in 12 hrs....78/12 = 6.50 per hr

for 20 hrs...
6.50 * 20 = $ 130 <==

Answer:

$130

Step-by-step explanation:

This is a direct proportionality between the amount he makes and the time worked. As the time increases, so does the amount he makes and vice versa.

Let the amount made be A and the time T

A ∝ T,

A = KT where K is the constant of proportionality

where Jon makes $78 in 12 hours of work, A = 78, T = 12

78 = 12K

K = 6.5

A = 6.5T

In 20 hours of work, T = 20

A = 6.5 × 20

A = $130
