John has four more nickels than dimes in his pocket, for a total of $1.25. What is an equation that could be used to determine the number of dimes, x, in his pocket?

Answers

Answer 1
The correct equation would be: 0.05(x+4) + 0.10x = $1.25

A nickel is worth 5 cents. A dime is worth 10 cents.

no. of nickels = x + 4
no. of dimes = x

nickels + dimes = 1.25
0.05(x + 4) + 0.10x = 1.25
0.05x + 0.20 + 0.10x = 1.25
0.15x = 1.25 - 0.20
0.15x = 1.05
0.15x/ 0.15 = 1.05 / 0.15
x = 7 *no. of dimes.

no. of nickels = x + 4 = 7 + 4 = 11

To check:
0.05(11) + 0.10(7) = 1.25
0.55 + 0.70 = 1.25
1.25 = 1.25

A polynomial function is also:

a. infinite.
d. indiscriminate.
c. rational.
d. irrational.

Answers

Answer:

A. Infinite

Step-by-step explanation:

First lets define a polynomial function. A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation.

Well Infinite functions are functions that have an answer of all real numbers right? So that would make sense.

Honestly I've never heard of an indiscriminate.

Irrational function has answers that can only be zero or above never negative because its inside a radical sign and radical answers can't be negative. If you've ever seen the graph of an irrational function though it looks nothing like a polynomial.

A rational function is a function that the polynomial in it does not equal zero.

A polynomial function is not always a rational function though. But it can be.

1 + tan- 300​

Answers

Question:

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex]

Answer:

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex][tex]= sin(60^{\circ})[/tex]

Step-by-step explanation:

Given

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex]

Required

Simplify

In trigonometry:

[tex]tan(30^{\circ}) = \frac{1}{\sqrt{3}}[/tex]

So, the expression becomes:

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{2 * \frac{1}{\sqrt{3}}}{1 + (\frac{1}{\sqrt{3}})^2}[/tex]

Simplify the denominator

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{2 * \frac{1}{\sqrt{3}}}{1 + \frac{1}{3}}[/tex]

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{\frac{2}{\sqrt{3}}}{1 + \frac{1}{3}}[/tex]

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{\frac{2}{\sqrt{3}}}{ \frac{3+1}{3}}[/tex]

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{\frac{2}{\sqrt{3}}}{ \frac{4}{3}}[/tex]

Express the fraction as:

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex][tex]= \frac{2}{\sqrt 3} / \frac{4}{3}[/tex]

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{2}{\sqrt 3} * \frac{3}{4}[/tex]

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{1}{\sqrt 3} * \frac{3}{2}[/tex]

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{3}{2\sqrt 3}[/tex]

Rationalize

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{3}{2\sqrt 3} * \frac{\sqrt{3}}{\sqrt{3}}[/tex]

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{3\sqrt{3}}{2* 3}[/tex]

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{\sqrt{3}}{2}[/tex]

In trigonometry:

[tex]sin(60^{\circ}) = \frac{\sqrt{3}}{2}[/tex]

A roofing contractor has 29 bundles of roofing shingles that he needs to carry up a ladder and put onto a roof he carries two bundles at a time how many bundles are still on the ground after his seventh trip up the ladder

Answers

Answer:

15 bundles of roofing shingles

Step-by-step explanation:

Total bundles of roofing shingles = 29

He carries two bundles at a time

How many bundles are still on the ground after his seventh trip up the ladder?

First trip = 2 bundles of roofing shingles

Second trip = 2 bundles of roofing shingles

Third trip = 2 bundles of roofing shingles

Fourth trip = 2 bundles of roofing shingles

Fifth trip = 2 bundles of roofing shingles

Sixth trip = 2 bundles of roofing shingles

Seventh trip = 2 bundles of roofing shingles

Total bundles of roofing shingles carried in 7 trips = 2 + 2 + 2 + 2 + 2 + 2 + 2

= 14 bundles of roofing shingles

Bundles still on ground after 7 trips = Total bundles of roofing shingles - Total bundles of roofing shingles carried in 7 trips

= 29 - 14

= 15 bundles of roofing shingles

Rewrite 300 in simplest radical form?

Answers

Answer:

10√3

Step-by-step explanation:

First we write the square root of 300 like this:

√300

The largest perfect square of the factors of 300 is 100. We can therefore convert √300 like this:

√100 × 3

Next, we separate the numbers inside the √ as such:

√100 × √3

√100 is a perfect square that equals 10. We can therefore put 10 outside the radical and get the final answer to square root of 300 in simplest radical form as follows:

10√3

If 2a+4b=5 and a is equal to three times b, what is 3a?

Answers

Answer:

3a=4.5

Step-by-step explanation:

it says that "a is equal to 3 times b", which translates to a=3b

We can substitute a as 3b in 2a+4b=5

2(3b)+4b=5

multiply

6b+4b=5

add

10b=5

divide by 10

b=1/2

since it's given that a=3b, we can multiply 1/2 by 3

a=3/2

3a is 3 times a, so we can mutiply 3(3/2)=9/2=4.5

Find the volume of a pyramid with a square base, where the perimeter of the base is 15.8\text{ ft}15.8 ft and the height of the pyramid is 20.4\text{ ft}20.4 ft. Round your answer to the nearest tenth of a cubic foot.

Answers

Answer:

The volume of the Pyramid is 318.3 cubic foot

Step-by-step explanation:

Here, we want to calculate the volume of the Pyramid

Mathematically, the volume of the pyramid is the area of the square base multiplied by the height of the Pyramid.

Since the perimeter is 15.8 and the formula for the perimeter is 4L

we can get the length of the side of the square

The length of the side will be 15.8/4 = 3.95

The area of the square base is thus equal to;

3.95^2 = 15.6025 square feet

Now we can multiply this by the height

Mathematically, that will be;

15.6025 * 20.4 = 318.291 which is approximately 318.3 cubic foot

106.1 ft

Kristen is making accessories for the soccer team. She uses 763.98 inches of fabric on headbands for 32 players and 2 coaches. She also uses 272.32 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Answer:

22.47 in of fabric on headbands

8.51 in of fabric on wristbands

Step-by-step explanation:

Step one:

given data

the total amount of person players plus coaches= 32+2= 34

for each person she uses = 763.98/32= 22.47 in of fabric on headbands

She also uses 272.32 inches of fabric on wristbands for just the players

For each player, she will use= 272.32/32= 8.51 in of fabric

Hence for each player, she used

22.47 in of fabric on headbands

8.51 in of fabric on wristbands.

I'm going to answer the solution in Point-Slope and Slope-Intercept.

Slope - Intercept form is this: y = mx + b

We know that (x, y) is a point on the line, m is the slope, and b is the y-intercept.

From the given information we have that it has a slope of 2 (m = 2), and one of the points on the line is (3, 9) which means that (x = 3, y = 9)

Plugging in we get:

y = mx + b

9 = 2*3 + b

9 = 6 + b

b = 3

Therefore the y-intercept is 3. After having this information we can construct our equation.

We now have to put this in the point-slope form which is: (y - y1) = m(x - x1)

Transferring what we had before we can plugin and get y - 9 = 2(x - 3)

Comment down if you have any queries or any questions on the solution. Tell me as soon as possible. Good luck in your Algebra Pursuit!! :)

Enjoy!! I put the answer in both point-slope and slope-intercept if you haven't noticed!! :)

What is a segment bisector?

A segment bisector is a line, ray, line segment, or point that divides a line segment into two equal halves at its center. A line segment bisector divides a line segment into two equally sized pieces. It goes through the segments halfway. Line PQ in the image below serves as AB's bisector.

It is given that,

RS = 7y-4

ST = 2y+6

Lines or portions of lines that cut across the middle are known as segment bisectors. We designate the segments with segment marks when two segments are congruent. According to the midpoint formula, the midpoint for the endpoints (x₁,y₁) and (x₂,y₂) is ((x₁+x₂)/2,(y₁+y₂)/2).

We have to find the segment bisector of the RT.

RT = RS + ST

RT = 7y-4 + 2y+6

RT =9y+2

Thus, the value of RT will be 9y+2 and the segment bisector of RT will be 4.5y+1.
