Fred finishes his job 2 days before and makes 10 boxes than Georgiana

each day, the number of boxes Georgiana makes each day are 10 boxes.

The number of boxes Fred plans to make = 160 boxes

Number of boxes Georgiana plans to make = 25% fewer than Fred

Number of boxes Fred makes each day = 10 more than the number of boxes Georgina makes

Number of days before the convention Fred finishes his job = 2 days before the convention

Number of days after the convention Georgina completes her job = 2 days after the convention starts

Let x represent the number of boxes Fred makes per day and let y

represent the number it takes Fred to complete his job, we have the

following equations;

x × y = 160

(x - 10) × (y + 4) = 0.75 × 160 = 120

Which gives;

[tex]\mathbf{(x - 10) \times \left(\dfrac{160}{x} +4 \right)} = 120[/tex]

4·x² + 120·x - 1600 = 120·x

4·x² + 120·x - 120·x = 1600

4·x² = 1600

x = √(1600 ÷ 4) = 20

The number of boxes Fred makes each day, x = 20 boxes

Number of days Fred takes, y = 160 ÷ 20 = 8

Step-by-step explanation:

p + r = 2,684

p = r + 280

r + 280 + r = 2,684

2r = 2,404

r = 1,202

p = 1,202 + 280 = 1,482

Answer:

[tex]\Huge\boxed{x=50.3}[/tex]

Step-by-step explanation:

Hello There!

Once again here are the Trigonometric Ratios

Sin = opposite divided by hypotenuse

Cos = adjacent divided by hypotenuse

Tan = opposite divided by adjacent

We need to find the measure of angle O

We are given the opposite side length (89) and the adjacent side length (74)

This corresponds with tangent so we are going to use tangent to solve for x

Now we create an equation: (remember tangent = opposite divided by adjacent)

[tex]tan(x)=\frac{89}{74} \\\frac{89}{74} =1.202702703\\[/tex]

now we have

[tex]tan(x)=1.202702703[/tex]

once again we want to isolate the variable (x)

To do so we need to get rid of tan by taking the inverse of tan (arctan^-1) and applying that to each side

[tex]arctan^-^1(tan(x))=x\\arctan^-^1(1.202702703)=50.25780917[/tex]

finally we want to round to the nearest tenth

50.25

its a five so we raise the 2 to a 3

and we're left with

x = 50.3

The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices . Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.

the first step in solving an equation is to make the equation as simple as possible. This means that you need to start by using the golden rule of equation solving and the order of operations, PEMDAS, to make the expression on each side of the equals sign as simple as possible.

Answer:

The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently. In this example, the ordered pair (4,7) is the solution to the system of linear equations.

The  fraction of the children in the group that contains both dog and a cat is [tex]\frac{17}{12}[/tex]

Step-by-step explanation:

The fraction of the children in the group that contains both dog and a cat is presented below:

= Pet dog + cat

[tex]= \frac{2}{3} + \frac{3}{4}\\\\= \frac{8 + 9}{12} \\\\= \frac{17}{12}[/tex]

Hence, the fraction of the children in the group that contains both dog and a cat is [tex]\frac{17}{12}[/tex]

The cost of rent from 8:00 AM to 2:00 PM is $21 and for 2:15 PM is $22.5

A unit rate means a rate for one of something.

Given is a graph showing the cost of renting snowshoes for corresponding hours,

From 8:00 AM to 2:00 PM = 6 hours

According to graph,

The rent for 6 hours is $21

In an hour, the rent is $6

So, for 15 minutes = $1.5

Therefore, 8:00 AM to 2:15 PM = 6 hours + 15 minutes

Cost = 21+1.5

Cost = $22.5

Hence, The cost of rent from 8:00 AM to 2:00 PM is $21 and for 2:15 PM is $22.5

Answer:

A multiple of 3 can be written 3n where n is a positive integer.

So 3 consecutive multiples of 3 can be written

3n,3n+3,3n+6

The sum of these is 36

3n+3n+3+3n+6=36

9n+9=36

Divide through by 9

n+1=4

n=3

If n=3 then 3n=9 and the three consecutive multiples of three are 9, 12 and 15 which do indeed total 36
