[tex]3\frac{1}{5} \times 2\frac{1}{5}[/tex]

Lets convert it into improper fraction.

[tex]\frac{16}{5} \times \frac{11}{5} = \frac{16 \times 11}{5 \times 5} = \frac{176}{25}[/tex]

Lets convert [tex]\frac{176}{25}[/tex] into a mixed fraction.

[tex]=> \frac{176}{25} = 7\frac{1}{25} = 7.04[/tex]

Rounding off 7.04 gives 7 and rounding 7 further gives 10.

So , the estimate of the product is 10

Answer: [tex]\boxed{\boxed{\sf\frac{5}{12}=0.416666667}}[/tex]Solution Steps:

______________________________

1.) Find the LCF of 6 and 4: [tex]6,4=12[/tex]

 - We do this because in order to add these, they must have the same denominator. So you must find the LCF, (Least Common Factor) of 6 and 4.

2.) Convert the fractions to have the same denominator: [tex]\frac{1}{6}=\frac{2}{12}[/tex] [tex]\frac{1}{4}=\frac{3}{12}[/tex]

 - [tex]\frac{1}{6}[/tex] changes to [tex]\frac{2}{12}[/tex] by multiplying the numerator and denominator by 2. And  [tex]\frac{1}{4}[/tex] changes to [tex]\frac{3}{12}[/tex] because you multiply the numerator and denominator by 3.

3.) Add the numerators: [tex]2+3=5[/tex]

 - Since both fractions have the same denominator all you have to do is add the numerators together.

Answers

Complete question :

A, B, C and D are four towns. B is 30 kilometres due east of A. C is due 30 kilometres north of A. D is due 45 kilometres due south of A. Work out the bearing of B from C.

Answer:

44°

Step-by-step explanation:

From the diagram sketched, we have a right angled d triangle, thus we can apply Pythagoras ;

Using the relation :

Tanθ = opposite / Adjacent

Tan θ = 30 / 30

Tanθ = 1

θ = tan^-1(1)

θ = 45°

Hence, bearing of B from C is 45°

Solve each compound inequality. Graph your solutions.
5 + m > 4 or 7m< -35

Answers

Answer:

Solving the inequality [tex]5 + m > 4\: or\: 7m< -35[/tex] we get [tex]\mathbf{m>-1\:or\: \:m<-5}[/tex]

The graph of the inequality is shown in figure attached.

Step-by-step explanation:

We need to Solve each compound inequality [tex]5 + m > 4\: or\: 7m< -35[/tex]

Solving the inequalities

For solving compound inequalities we solve both inequalities simultaneously and find the value of m.

For solving 5+m > 4, we subtract 5 from both sides.

While solving 7m < -35, we divide both sides by 7 to get value of m

Applying these functions we get:

[tex]5 + m > 4\: or\: 7m< -35\\m>4-5\:or\:m<\frac{-35}{7}\\m>-1\:or\:m<-5[/tex]

So, solving the inequality [tex]5 + m > 4\: or\: 7m< -35[/tex] we get [tex]\mathbf{m>-1\:or\: \:m<-5}[/tex]

The graph of the inequality is shown in figure attached.

If the slope is a negative number, the line should be negative as well, meaning the line should be going downwards (left to right always)

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.

Given is the student council hires a dj to play music at the school dance. They pay DJ Dan for 3.5 h at his hourly rate plus a 125$ setup fee. the total cost is $405.

Assume that the hourly rate is $[x]. Than, we can write -

3.5x + 125 = 405

3.5x = 405 - 125

3.5x = 280

x = (280/3.5)

x = 80

Therefore, DJ Dan's hourly rate will be $80.

Which systems of equations intersect at point A in this graph?

Answers

Answer:

The point of intersection of the system of equations is:

(x, y) =  (-2, 1)

The correct system of equations intersect at point A in this graph will be:

[tex]\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}[/tex]

Thus, the second option is correct.

Step-by-step explanation:

Given the point

A (-2, 1)

Let us check the system of equations to determine whether it intersect at point A in this graph.

Given the system of equations

[tex]\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}[/tex]

Arrange equation variable for elimination

[tex]\begin{bmatrix}y-4x=9\\ y+3x=-5\end{bmatrix}[/tex]

so

[tex]y+3x=-5[/tex]

[tex]-[/tex]

[tex]\underline{y-4x=9}[/tex]

[tex]7x=-14[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}y-4x=9\\ 7x=-14\end{bmatrix}[/tex]

Solve 7x = -14 for x

[tex]7x=-14[/tex]

Divide both sides by 7

[tex]\frac{7x}{7}=\frac{-14}{7}[/tex]

Simplify

[tex]x = -2[/tex]

For y - 4x = 9 plug in x = 2

[tex]y-4\left(-2\right)=9[/tex]

[tex]y+4\cdot \:2=9[/tex]

[tex]y+8=9[/tex]

Subtract 8 from both sides

[tex]y+8-8=9-8[/tex]

Simplify

y = 1

Thus, the solution to the system of equations is:

(x, y) = (-2, 1)

From the attached graph, it is also clear that the system of equations intersects at point x = -2, and y = 1.

In other words, the point of intersection of the system of equations is:

(x, y) =  (-2, 1)

Therefore, the correct system of equations intersect at point A in this graph will be:

[tex]\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}[/tex]

Thus, the second option is correct.

- The new apartment you ałe about to sign a one-year lease on is $1,500 per month. The lease
requires you to put up first month's rent and a $750 security deposit to move in. In addition,
keeping your cat will cost an additional $300 for a pet deposit. How much do you need to write a
check for to the landlord at the time of move in?

Answers

Answer:

Total amount = $2550

Step-by-step explanation:

To move in the apartment payments to be done,

1). First month rent = $1500

2). Security deposit = $750

3). Pet deposit = $300

Total payment to be done = 1500 + 750 + 300

                                            = $2550

Therefore, total amount to be paid = $2550

I will write a check of $2550.

Amy hikes 6 miles from a ranger station to a waterfall and back again. She hikes 1 mile/hour faster on the way back. Function represents Amy's total time spent hiking,
and x represents amy's hiking speed in miles/hour

Answers

It is the time it takes Amy to hike to the waterfall.

The term [tex]\frac{6}{x}[/tex]  describes the time it takes Amy to hike to the waterfall.

The correct answer is an option (C)

What is speed?

"It is defined as the distance traveled per unit times."

What is relation?

"It defines a relation between input values and output values."

For given example,

Amy hikes 6 miles from a ranger station to a waterfall and back again. She hikes 1 mile/hour faster on the way back.

we have been given a function [tex]T(x)=\frac{6}{x}+\frac{6}{x+1}[/tex]

This function represents Amy's total time spent hiking,

and x represents Amy's hiking speed in miles/hour.

Let 't' be the time required to reach Amy from ranger hills to a waterfall.

As 'x' represents Amy's hiking speed in miles/hour and Amy hikes 6 miles from a ranger station to a waterfall.

Using the formula of speed,

⇒ x = 6/t

t = 6/x

Therefore, the term [tex]\frac{6}{x}[/tex]  describes the time it takes Amy to hike to the waterfall.

The correct answer is an option (C)

-1 < x ≤ 3

Step-by-step explanation:

First, we need to simplify this inequality.

9 > -5x + 4 ≥ -11 (Given)

5 > -5x ≥ -15 (Subtract 4 on both sides)

-1 < x ≤ 3 (Divide -5 on both sides)

Note that the signs flip due to dividing by a negative number.

Answer:

[tex]-1<x\leq3[/tex]

Step-by-step explanation:

Let's take two equations from this and them put them back together! So:

9>-5x+4

and

[tex]-5x+4\geq -11[/tex]

For the first one:

9>-5x+4

Subtract 4 from both sides

5>-5x

Then divide by -5 (Remember to change the direction of the sign!):

-1<x

Now onto the second one:

[tex]-5x+4\geq -11[/tex]

Subtract 4 from both sides:a

[tex]-5x\geq -15[/tex]

Then divide by -5 (Remember to change the direction of the sign!):

[tex]x\leq 3[/tex]

Now add the equations back together:

[tex]-1<x\leq3[/tex]
