A merchant has coffee worth $40 a pound that she wishes to mix

Mathematics
1 answer:
pantera1 [17]2 years ago
8 0

Answer:

Step-by-step explanation:

let x = the number of pounds of cheaper coffee.

Since the merchant is mixing this with more expensive coffee, then

x + 60 = the number of pounds of medium priced mixed coffee.

The equation is gotten from this

+  =  

(x)($40)  + (60)($90)   = (x + 60)($70) or

            40x + 5400 = 70(x + 60)

Solve that equation and get x = 40

Answer: 40 pounds of $40 coffee.

i hope this helped

14 = 2y/5 what is the solution?
Gnom [1K]

Answer:

y=35

Step-by-step explanation:

y in (-oo:+oo)

14 = (2*y)/5 // - (2*y)/5

14-((2*y)/5) = 0

(-2/5)*y+14 = 0

14-2/5*y = 0 // - 14

-2/5*y = -14 // : -2/5

y = -14/(-2/5)

y = 35

y = 35

Describe the correct answer to this problem including units what is the surface area of the figure
Brrunno [24]

Answer:

<h2>        A = 22.5π ft² ≈ 70.686 ft²</h2>

Step-by-step explanation:

A = π×(2.5)² + π×2.5×6.5 = 6.25π + 16.25π = 22.5π ≈ 70.686 ft²

{6.5 ft is not a height, it's slant length}

Can you help with did pretty please I'm stuck help just a, c ,d thanks luv.
Misha Larkins [42]

Answer:

a) The slope of the function is 3.

c) The equation is represented by n(t) = 3\cdot t + 35.

d) The y-intercept of the function is 35.

Step-by-step explanation:

a) According to the statement, we must assume that number of pieces of mail that must be hand-sorted (dependent variable) is represented by a linear function in terms of time (independent variable). That is:

n(t) = m\cdot t + n_{o} (1)

Where:

m - Slope, measured in number of pieces per minute.

t - Time, measured in minutes.

n_{o} - Initial number of pieces of mail that must be hand-sorted (y-intercept), measured in pieces.

n - Current number of pieces of mail that must be hand-sorted, measured in pieces.

From Geometry, we know that a line can be formed by know two distinct points. If we know that n(15\,min) = 80\,p and n(45\,min) = 170\,p, then the following system of linear equations is formed:

15\cdot m + n_{o} = 80 (2)

45\cdot m + n_{o} = 170 (3)

The solution of the system of equations is:

m = 3 and n_{o} = 35

The slope of the function is 3.

c) By (1) and using results from a) we conclude that the equation function is:

n(t) = 3\cdot t + 35 (4)

d) The y-intercept of the function is 35.
