Marshall is comparing different companies that rent sound systems The total cost, y , for each company includes a used rental fee plus an additional fee based on the number of hours, x , the sound system is rented. Which company had the lowest additional fee per hour for renting a sound system?

Answer:

43.

Step-by-step explanation:

Follow PEMDAS (Parentheses, exponents, multiply, divide, add, subtract). First you do 8-4 which is 4, then you multiply 4 by 4 which is 16 since you multiply next, then you add 27 to 16 which then gets you to 43.

Each piece is 1.12 meters long

Step-by-step explanation:

7 equal pieces = divide x by 7

equation: 7.84 / 7

Answer:

2m/s²

Step-by-step explanation:

acceleration = change in velocity/time taken

a  = v-u/t

Given

v = 15m/s

u = 5m/s

time t = 5secs

Substitute

a = 15 - 5/5

a = 10/5

a = 2m/s²

Hence Ellie’s acceleration is 2m/s²

Answer:

$4.50x = $127.50 - $87

x = $40.50 / $4.50

x = 9

Step-by-step explanation:

The amount she can spend on bracelets is the total amount she wants to spend less the cost of the shirt

$4.50x = $127.50 - $87

4.50x = 40.50

divide bot side by 4.5

x = 9

Answer:

option D. 10

Step-by-step explanation:

[tex]\frac{34}{85} = \frac{4}{x}\\\\34 \times x = 4 \times 85\\\\x = \frac{340}{34} = 10[/tex]

Answer:

x = 10

Step-by-step explanation:

[tex] \dfrac{34}{85} = \dfrac{4}{x} [/tex]

Cross multiply.

34x = 4 × 85

34x = 340

Divide both sides by 34.

x = 10

Answer:

36 computadores deben ser reparados.

Step-by-step explanation:

Dado que en una oficina hay 96 computadores en total, y la razón entre los computadores que deben ser reparados y aquellos que se encuentran operativos es 3:5, para determinar cuántos computadores de la oficina deben ser reparados en total se debe realizar el siguiente cálculo:

(96 / (3+5)) x 3 = computadores que deben ser reparados

(96 / 8) x 3 = computadores que deben ser reparados

12 x 3 = computadores que deben ser reparados

36 = X

Por lo tanto, 36 computadores deben ser reparados.

Total distance of the girls walk all together is 7/6 of a mile.

Here,

Given that;

Amy and Myra each walked from their houses to the mall.

Amy walked one half a mile and Myra walked two-thirds of a mile.

We have to find the total distance of the girls walk together.

What is Distance?

Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

Now,

Amy walked one half a mile.

⇒ 1/2

Myra walked two-thirds of a mile.

⇒ 2/3

Hence,

Total distance of the girls when they walk together = [tex]\frac{1}{2} + \frac{2}{3}[/tex]

                                                                              = [tex]\frac{3+4}{6}[/tex]

                                                                              = [tex]\frac{7}{6}[/tex]

So, Total distance of the girls walk all together is 7/6 of a mile.

Answer:

g = 81.

Step-by-step explanation:

f = k/√g    where k is a constant

When f = 12 g = 36, so:

12 = k/√36 = k/6

k = 12*6 = 72.

So the relation is:

f = 72/√g

When f = 8:

8 = 72/√g

8√g = 72

√g = 72/8 = 9

g = 9^2 = 81.

Answer:

let us consider a positive integer a

divided the positive integer a by 3, and let r be the remainder and B be the quotient and such that.

Answer:

648 inches

Step-by-step explanation:

First, you do 14 times 12 times 2 and get 336.

Next, you do 14 times 6 times 2 and get 168.

Then you do 6 times 12 times 2 and get 144.

Now add 336, 168, and 144 together to get 648.

Answer:

No

Step-by-step explanation:

Technically, if you didn't turn anything in then no. If it is truly 80% of your final grade then not turning anything in would drop your grade to an F immediately. Although for a single project to be worth 80% of the entire year's grade seems off. Usually, finals and projects are a large percentage, but are more around the 25% range and not 80%. Otherwise, a student could not do anything the entire year and simply do the project and still pass with a B. That is why the grading system is not usually designed like this.

Step-by-step explanation:

l= 12

w= 9

h= 2

Substitute into the equation

S= 2(lw+ wh + hl)

S= 2( 12x9 + 9x2+ 12x2)

S= 2( 108+ 18 + 24)

S= 2( 150)

S= 300

Answer:

36

Step-by-step explanation:

Counting the squares: base = 12, height = 9.

We will use pythagorean theorem to find the third side.

Let it be x.

So,

   [tex]x^2 = 12^2 + 9^2\\x^2 = 144 + 8 1 = 225\\x = 15[/tex]

Perimeter of triangle = sum lengths of all sides

                                = 12 + 9 + 15

                                = 36 units
