Answer:

N = Q/3  -  V

Step-by-step explanation:

Q = 2N + 3V solve for N

Subtract 3V from both sides

Q - 3V = 3N

Divide both sides by 3

(Q - 3V)/3 = N

Q/3 - V = N

or

N = Q/3  -  V

Addison's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 70 espressos in all
Valentin [98]

Answer:

The number of single-shot espressos sold by the cafe was 49.

Step-by-step explanation:

It is provided that Addison's Cafe offers two kinds of espresso: single-shot and double-shot.

Total number of espressos sold by the cafe yesterday afternoon was,

<em>N</em> = 70

The proportion of single-shot espresso sold was, <em>p</em> = 0.70.

Let <em>X</em> = number of single-shot espressos sold.

Compute the number of single-shot espressos sold by the cafe as follows:

E(X)=N\times p

         =70\times 0.70\\=49

Thus, the number of single-shot espressos sold by the cafe was 49.

$2,500 principal earning 4%, compounded quarterly, after 4 years $40,000.00 $41,600.00 $2,931.45 $2,924.65
AURORKA [14]

Answer:

Amount= $2933.2

Step-by-step explanation:

The interest of $2,500 principal earning with rate of 4%, compounded quarterly, after 4 years

A= p(1+r/n)^(nt)

P= $2500

r= 4/100= 0.04

t= 4

n = 4*4= 16

A= 2500(1+0.04/16)^(16*4)

A= 2500(1+0.0025)^(64)

A= 2500(1.0025)^64

A= 2500(1.17328)

A= 2933.2

Amount= $2933.2

Which expression is equivalent to the following complex fraction?
Sedbober [7]

Answer:

  \dfrac{2(y-2x)}{3y-5x}

Step-by-step explanation:

When you simplify the numerator and the denominator, you find they both have denominators of xy. So, the ratio of those is the ratio of their numerators.

  \dfrac{\dfrac{2}{x}-\dfrac{4}{y}}{\dfrac{-5}{y}+\dfrac{3}{x}}=\dfrac{\left(\dfrac{2y-4x}{xy}\right)}{\left(\dfrac{-5x+3y}{xy}\right)}=\dfrac{2y-4x}{-5x+3y}\\\\=\boxed{\dfrac{2(y-2x)}{3y-5x}}

Max observes the zoo and the library from a helicopter flying at a height of 400 times square root of 3 feet above the ground, a
-BARSIC- [3]

Answer: First option: 800 feet

Solution:

Height: h=400 sqrt(3)

Distance between the zoo and the point in the ground below the helicopter: d1=?

Distance between the library and the point in the ground below the helicopter: d2=?

Distance between the zoo and the library: d=?

d=d2-d1


tan 60°= h/d1

sqrt(3)=400 sqrt(3) / d1

Solving for d1:

sqrt(3) d1 = 400 sqrt(3)

d1= 400 sqrt(3) / sqrt(3)

d1=400


tan 30°= h/d2

sqrt(3) / 3=400 sqrt(3) / d2

Solving for d2: Cross multiplication:

sqrt(3) d2 = 3 [ 400 sqrt(3) ]

sqrt(3) d2 = 1,200 sqrt(3)

d2= 1,200 sqrt(3) / sqrt(3)

d2=1,200


d=d2-d1

d=1,200 feet - 400 feet

d=800 feet
