Answer:

28 minutes

Step-by-step explanation:

100 yards times the 12 minutes he walked = 1200 yards. 6000-1200=4800

4800÷300=16

16 + 12 = 28

Answer:

28 Minutes

Step-by-step explanation:

The library is 6000 yd from the house.

He walks at a rate of 100 yd per minute for 12 minutes, which is 1200 yd of progress.

He bikes the rest of the 4800 yd on his bike at a rate of 300 yd per minute.

4800/300=16 minutes.

16+12=28 minutes.

Answer:

Step-by-step explanation:

Let the area of the two triangles be expressed as;

f(x)= 4x^2+6x

g(x)=3x^2-x

Taking the difference

h(x) = f(x) - g(x)

h(x) = 4x ^2+6x - 3x^2-x

Collect like terms'

h(x) = 4x ^2 - 3x^2+6x-x

h(x) = x ^2 + 5x

Hence the difference is  x^2 + 5x

Note that the functions were assumed. The same methos can be applied to any other given functions.

Answer:

B: h(x) = 4x2 – 4x + 11

Answer:

479.33

Step-by-step explanation:

10/30 is the same as 1/3 or 33.34%.

Multiply the fraction to the original price then subtract.

719 * 1/3 = 239.67

719 - 239.67 = 479.33

Answer:

The first step would be to distribute that 2 into the numbers in the parenthesis.

Step-by-step explanation:

Answer:

Step-by-step explanation:

I feel like there are many ways to begin this problem, but I'd distribute the 2(x+7) so that you are left with 2x+14. This way you can add 2x and 3x and subtract 14 to the other side.

Given:

'a' and 'b' are the intercepts made  by a straight-line with the co- ordinate axes.

3a = b and the line  pass through the point (1, 3).

To find:

The equation of the line.

Solution:

The intercept form of a line is

[tex]\dfrac{x}{a}+\dfrac{y}{b}=1[/tex]         ...(i)

where, a is x-intercept and b is y-intercept.

We have, 3a=b.

[tex]\dfrac{x}{a}+\dfrac{y}{3a}=1[/tex]           ...(ii)

The line  pass through the point (1, 3). So, putting x=1 and y=3, we get

[tex]\dfrac{1}{a}+\dfrac{3}{3a}=1[/tex]

[tex]\dfrac{1}{a}+\dfrac{1}{a}=1[/tex]

[tex]\dfrac{2}{a}=1[/tex]

Multiply both sides by a.

[tex]2=a[/tex]

The value of a is 2. So, x-intercept is 2.

Putting a=2 in [tex]b=3a[/tex], we get

[tex]b=3(2)[/tex]

[tex]b=6[/tex]

The value of b is 6. So, y-intercept is 6.

Putting a=2 and b=6 in (i), we get

[tex]\dfrac{x}{2}+\dfrac{y}{6}=1[/tex]

Therefore, the equation of the required line in intercept form is [tex]\dfrac{x}{2}+\dfrac{y}{6}=1[/tex].

Answer:

The inverse of f is

[tex]g(x) = 2x[/tex]

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=\frac{1}{2}x[/tex]

A function g is the inverse of function f if for y = f(x), x = g(y)

[tex]y=\frac{1}{2}x[/tex]

Replace x with y

[tex]x=\frac{1}{2}y[/tex]

Solve for y

[tex]y = 2x[/tex]

Therefore, the inverse of f is

[tex]g(x) = 2x[/tex]

Answer:

There is no point where x = 3.5

Step-by-step explanation:

Given the inequality

5x – 3 > 14.5

We are to find the range of all values of x

Add 3 to both sides of the equation;

5x - 3 + 3 > 14.5+ 3

5x > 17.5

x > 17.5/5

x > 3.5

Also for the inequality;

[tex]\frac{2x+5}{3} <4\\[/tex]

Cross multiply;

[tex]2x+5 < 3(4)\\2x + 5 < 12\\[/tex]

Subtract from both sides;

[tex]2x + 5-5 < 12-5\\2x < 7\\x<7/2\\x<3.5[/tex]

The solution to both inequalities are x > 3.5 and x < 3.5. Since there is no point where x = 3.5, hence the solution will have solution on all real numbers except at x = 3.5

Answer:

When solving the first inequality, you get x > 3.5. When solving the second inequality, you get x < 3.5. The solution of an "or” compound in equality is everything in both solution sets, so the solution set is all of the numbers less than 3.5 and greater than 3.5. Since neither of the inequalities includes 3.5, the compound inequality has a solution of all real numbers except 3.5.

Answer:

3/5

Step-by-step explanation:

We want to find the fraction of the original branch that remains, so we will assume a length of the branch in order to make our calculation easier.

Since Kim marks it off in thirds and fifths, let's find the least common multiple of 3 & 5.

Least common multiple of 3 & 5 is 15.

Thus,let's make the length of the branch to be 15-meter long.

Now, if the branch is 15 m long, considering the markings of thirds and fifths, the branch would be cut at:

3, 5, 6, 9, 10, 12 meters.

We are told that She then breaks the branch along all the markings and removes one piece of every distinct length. Thus;

Distinct lengths are;

3 metres

5 - 3 = 2 metres

10 - 9 = 1 meter

Total she removes = 3 + 2 + 1 = 6 meters.

Total remaining is;

15 - 6 = 9 meters

Expressing this as a fraction of the original branch gives:

9/15

Divide both numerator and denominator by 3 to get; 3/5

Given:

[tex]h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}[/tex]

To find:

The recursive formula.

Solution:

We have,

[tex]h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}[/tex]

It is in the form of explicate formula of a GP, .i.e., [tex]a_n=ar^{n-1}[/tex].

Here, [tex]a=-91[/tex] and [tex]r=-\dfrac{1}{7}[/tex].

The recursive formula of a GP is

[tex]a_n=a_{n-1}\times r[/tex]

Using this the recursive formula for given problem is

[tex]h(n)=h(n-1)\times (-\dfrac{1}{7})[/tex]

Therefore, the required recursive formula is [tex]h(n)=h(n-1)\times (-\dfrac{1}{7})[/tex].

Answer:

$108

Step-by-step explanation:

Let number of rolls produced = [tex]x[/tex]

Total production cost = $300

Average production cost can be found by dividing the total production cost with the number of rolls produced.

Average production cost per roll = $[tex]\frac{300}{x}[/tex]

[tex]\frac{4}{5}[/tex] of the rolls were sold at a price 50% higher than the average production cost per roll.

i.e.

Money earned by selling [tex]\frac{4}{5}[/tex] of the rolls:

[tex]\dfrac{4}{5}x \times \dfrac{300}{x}\times \dfrac{150}{100}\\\Rightarrow \$360[/tex]

Money earned by selling the remaining the remaining rolls:

[tex]\dfrac{1}{5}x\times \dfrac{300}{x}\times \dfrac{80}{100}\\\Rightarrow \$48[/tex]

Total money earned by selling all the rolls = $360 + $48 = $408

Total profit can be calculated by subtracting the total production cost from the total money earned.

Total profit = $408 - $300 = $108
