Pre calculus question need help asap

Answer: 5%

Step-by-step explanation:

Since Ryan's take-home pay is $2,500 each month and the amount for gas is $125.

The percentage that Ryan uses on gas from his take-home pay will be:

= Amount used on gas / Take home pay × 100

= 125/2500 × 100

= 1/20 × 100

= 5%

He used 5% on gas.

Answer:

Step-by-step explanation:

first, i'm pretty sure that there's only one box of chocolates as stated in the problem, but if there's more i'm sorry.

you can use this equation:

6.49x + 8.32=27.79

remember not to use dollar signs in the equation! only use dollar signs in your answer - so don't use dollar signs now, unless specified by your teacher or guider ;)

hope this helped!!!

Answer:

Given function

#15 Find the inverse of h(x)

Substitute x with y and h(x) with x and solve for y:

The inverse is:

#16 The graph with both lines is attached.

The x- and y-intercepts of both functions have reversed values.

#17 Table of the inverse function  will contain same numbers with swapped domain and range.

Initial look is like this:

The rest of the table is filled in by finding the values:

Answer:

2/36 or 1/18

Step-by-step explanation:

rolling two dice produces 36 outcomes

rolling a 3 and a 6 is one outcome

rolling a 6 and a 3 is a second outcome

5x+7y=25

5x-2y=-65

subtract both of the equations

5x-5x=0

7y--2y= 7y+2y=9y

25--65=25+65=90

0+9y=90

9y=90

divide both sides by 9 to get y by itself

9y/9=90/9

cross out 9 and 9 which becomes 1*1*y=y

90/9=10

y=10

find x by using the substitution method

5x+7y=25

5x+7(10)=25

5x+70=25

move +70 to the other side

sign changes from +70 to -70

5x+70-70=25-70

5x=-45

divide both sides by 5 to get x by itself

5x/5=-45/5

cross out 5 and 5 then becomes 1*1*x=x

-45/5=-9

x=-9

answer:

(-9,10)

Step-by-step explanation:

area of a circle = [tex]\pi r^{2}[/tex]

circumference =[tex]2\pi r[/tex]

Okay so the center of the circle is the same for both of the circles lets take that value as m so the radius of the inner circle is 54 - m

we have the circumference of the inner circle which is 270.04 we can find the value of m using that

[tex]270.04=2\pi (54-m)\\270.04= 339.2-6.28m \\6.28m = 339.2-270.04\\m= 11.02[/tex]

the radius of the inner circle is therefore 42.98

and the full circle has a radius off 65.02

area of shaded region = area of full circle - area of inner circle

area of shaded region = [tex]\pi (65.02)^{2} - \pi (42.98)^{2}[/tex]

area of shaded region = [tex]13281.39 - 5803.4[/tex]

area of shaded region = 7478 rounded off to the nearest whole number

Answer: 25%

Step-by-step explanation:

3/4x=5700

x = 7600

7600 - 5700 = 1900

19/76 = 25/100 which is 25%

Hope this helps!

Answer:

y = 126° + 29° = 155°

Step-by-step explanation:

I think this may be a solution:

126°+29°=155°

So, y=155°

Answer:

[tex]n=4[/tex]

Step-by-step explanation:

Expand  −2(1−7n):    −2+14n

5n+34=−2+14n

Subtract 34 from both sides

5n+34−34=−2+14n−34

Simplify

5n=14n−36

Subtract 14n from both sides

5n−14n=14n−36−14n

Simplify

−9n=−36

Divide both sides by −9

−9n

−9 =

−36

−9

Answer:

45.5

Step-by-step explanation:

First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.

Answer:

$24.50

Step-by-step explanation:

10.50 * 2 1/3 = 24.50

I would appreciate brainliest, have an amazing day

Answer:

an = a1 + d(n - 1)

a88 = 4 + (-5)(88 - 1)

a88 = 4 + (-5)(87)

a88 = 4 - 435

a88 = -431

So, the 88th term of the arithmetic sequence is -431.

Answer:

Step-by-step explanation:

Let's find and use the intercepts.  They speed up graphing of lines.

y-intercept:  In y = 6 – 2x, let x = 0.  Then y = 6, and the y-intercept is (0, 6).

x-intercept:  In y = 6 – 2x, let y = 0.  Then 2x = 6, and x = 3.  The x-intercept is therefore (3, 0).

Plot these two points and then draw a line through both.

Answer:

The miles per day are: 3 1/12.

Step-by-step explanation:

With  the information provided, in order to find the miles per day you have to divide the number of miles he walked by 3 that is the number of days:

9 1/4÷3

In order to solve this, first you have to convert the mixed number to an improper fraction by multiplying the denominator for the whole number, add the numerator and this would be divided by the denominator:

(4*9)+1/4

36+1/4

37/4

Now, you divide this by 3:

37/4÷3

37/(4*3)

37/12

You can conver this fraction into a mixed number by dividing 37 by 12. 12 goes into 37 three times which would be the whole number. Then, three times 12 is 36 and the remainder is 1. So, 1 would be the numerator and the denominator stays th same which is 12. The mixed number is: 3 1/12.

According to this, the answer is that the miles per day are: 3 1/12.

Answer:

a = 5120

b = 1.25

Step-by-step explanation:

Let the exponential function representing the given table is,

f(x) = [tex]a(b)^x[/tex]

Here, f(x) = Number of views

x = Number of weeks

We choose two points from the given table and satisfy the equation of the function.

Let the points are (0, 5120) and (1, 6400)

For a point (0, 5120),

f(0) = a(b)⁰ = 5120

a = 5120

Now for the second point (1, 6400),

6400 = 5120(b)¹

b = [tex]\frac{6400}{5120}[/tex]

b = 1.25

Therefore, a = 5120 and b = 1.25 are the values.
