Maddie's office recycled a total of 12 kilograms of paper over 4 weeks. How many weeks will it take Maddie's office to recycle a total of 15 kilograms of paper? Assume the relationship is directly proportional.

Answer:

your answer is not perpendicular

Step-by-step explanation:

so first you put the y which is -2 and the -x with -3

[tex]-2=(-3)-4[/tex]

when you subtract the -3 from 4 you will get 7

[tex]4-(-3)=7[/tex]

7 is not equal to -2 so it is not perpendicular

[tex]7\neq -2[/tex]

Answer:

The total cost of meal is $65.34

Step-by-step explanation:

Price of the meal = $54

Sales tax on meal = 6%

Tip given= 15% on pre-tax amount

We need to find total cost of meal.

First finding sales tax amount:

We need to calculate 6% of 54

[tex]6\% \ of \ 54\\=6\% \times 54\\=\frac{6}{100}\times54\\=3.24[/tex]

So, the sales tax would be $3.24

Now, we need to find tip amount

We will find 15% of 54

[tex]15\% \ of \ 54\\=15\% \times 54\\=\frac{15}{100}\times54\\=8.1[/tex]

So, the tip given would be $8.1

The total cost of meal = Price of meal + Sales Tax + Tip

                                      = 54+3.24+8.1

                                      = 65.34

So, the total cost of meal is $65.34

Answer:

[tex] a_n = 31 - 3n\\\\

a_{30}= 59[/tex]

Step-by-step explanation:

Given Arithmetic sequence is:

28, 25, 22, 19, ...

a = 28, d = 25 - 28 = - 3,

nth term of an Arithmetic sequence is given as:

[tex] a_n = a + (n - 1) d\\[/tex]

Plugging a = 28 & d = - 3 in the above equation, we find:

[tex] a_n = 28 + (n - 1) (-3)\\\\

a_n = 28 - 3n +3\\\\

\huge\purple {\boxed {a_n = 31 - 3n}} \\(This \:is \:the \:required \:equation) \\\\

Plug \: n = 30, \: we \: find:\\\\

a_{30}= 31 - 3 \times 30\\\\

Answer:

The sides are 14.6, 14.6, 9.6

Step-by-step explanation:

Step one:

given

Perimeter= 49

let the equal sides of the triangle be x

so the third side will be x-5

hence the first side is=x

the second side =x

and the third side=x-5

the perimeter of triangle is

P= A+B+C

where A B and C represents all the sides

49=x+x+(x-5)

solve for x

49=2x+x-5

49=3x-5

49-5=3x

44=3x

x=44/3

x=14.6

Hence the third side is

=x-5=14.6-5

=9.6

The sides are 14.6, 14.6, 9.6

Answer:

18 for same length and 13 for 3 length

Step-by-step explanation:

Answer:

7.5 units

Step-by-step explanation:

First, create a proportion by picking 2 sides:

2.5/n = 5/15

Next, cross multiply:

5n = 37.5

Finally, divide both sides to isolate the variable:

7.5

Therefore your answer is 7.5 units.

Answer:

B

Step-by-step explanation:

Answer:

56

Step-by-step explanation:

The easiest way to solve this is by cross multiplying. We can make an equation to find the answer of this by simply taking a side from each triangle and then the variable and equal side on the other triangle, shown below.

[tex]let \: \: ? = x[/tex]

[tex] \frac{7}{49} = \frac{8}{x} [/tex]

Now we solve with cross multiplication

[tex]7 x = 392 \\ x = 56[/tex]

Now we know the mystery number is 56

Answer:

75°

Step-by-step explanation:

we can form a triangle to help us understand how to solve this problem:

                                                    puppy

∠ Leslie = 35°                                                   ∠ Surekha = 70°

If Leslie's angle is 35° and Surekha's angle is 70°, that gives us a total of 105°. Since the sum of the triangle's three angles is 180°, then the angle at which they will meet is 180° - 105° = 75°

In this exercise, we have to calculate the angle of the path that they met, so we will have:

75°

We know that the geometric figure in question is a triangle and that the sum of its internal angles must be equal to 180 degrees, thus:

[tex]180-105=X\\180-105=75\\[/tex]

Answer:C and E

Step-by-step explanation:

An employee earns $14 per hour and a trainer charges $20 for every 30 minutes of training plus a $5 tip are a constant rate per unit interval. Therefore, options A and E are the correct answers.

Given that, an employee earns $14 per hour.

When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.

A). Let the number of hours be x and the total money earned be y

So, y=14x

B). Let the money earn by an employee each year be a and total earning in a year be b.

So, b=a+3% of a

⇒ b=a+0.03a

⇒ b=1.03a

C) Let the number of months be m and the total charge be t

So, t=50+30m

D) Let cost of gym equipment be p, rate of change =8% and time period = 6 months

So, [tex]A=p(1-\frac{8}{100} )^{6t}=p(0.92)^{6t}[/tex]

E) Let the number of hour be x.

Here, 30 minutes = 1/2 hours

Total charge = 20+5x/2

An employee earns $14 per hour and a trainer charges $20 for every 30 minutes of training plus a $5 tip are a constant rate per unit interval. Therefore, options A and E are the correct answers.

Answer: The diagonals are thus equal, and divides the rectangle into right triangles, whereas the diagonals of a parallelogram are not equal and bisect it into two congruent triangles with angles depending on that of the parallelogram.

Answer:

(6, -1)

Step-by-step explanation:

Solve the System of Equations

2x + 3y = 9 and x − 2y = 8

Add 2y to both sides of the equation.

x = 8 + 2y 2x + 3y = 9

Replace all occurrences of x with 8 + 2y in each e quation.

Replace all occurrences of x in 2x + 3y = 9 with 8 + 2y. 2 (8 + 2y) + 3y = 9

x = 8 + 2y

Simplify 2 (8 + 2y) + 3y.

16 + 7y = 9

x = 8 + 2y

Solve for y in the first equation.

Move all terms not containing y to the right side of the equation.

7y = −7

x = 8 + 2y

Divide each term by 7 and simplify.  

y = −1

x = 8 + 2y

Replace all occurrences of y with −1 in each equation.

Replace all occurrences of y in x = 8 + 2y with −1. x = 8 + 2 (−1)

y = −1

Simplify 8 + 2 (−1).

x = 6

y = −1

The solution to the system is the complete set of ordered pairs that are valid solutions.

Answer:

1/15 yards

Step-by-step explanation:

Total yards of packing tape = 4 yards

Yards used for his father = 1 3/5 yards

Yards used for another package = 2 1/3 yards

Total yards used = 1 3/5 + 2 1/3

= 8/5 + 7/3

= 24+35/15

= 59/15 yards

How many yards of packing tape does Carlos have left

Total yards left = Total yards of packing tape - Total yards used

= 4 - 59/15

= 60-59/15

= 1/15

Total yards left = 1/15 yards
