Mathematics
1 answer:
Mariana [72]3 years ago
8 0

Answer:

n = 15.5

Step-by-step explanation:

(4+n)/(43+n) =1/3

3(4+n)= 1*(43 + n)

12 + 3n = 43 + n

3n - n = 43 - 12

2n = 31

n = 31/2= 15.5

Which equation could be used to create the graph?
Eva8 [605]

Answer:

C

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (9, 3) ← 2 points on the line

m = \frac{3-0}{9-0} = \frac{3}{9} = \frac{1}{3}, thus

y = \frac{1}{3} x

Or

y = \frac{x}{3} → C

a milk tank at a a dairy farm has the form of a rectangular prism. The tank is 3.5 feet wide. The width of the tank is 5/7 of it
AURORKA [14]

Answer:

17.5 cubic feet

1163.75 pounds

Step-by-step explanation:

Givens

L = 3.5                                    Given

W = 5/7  *  3.5                        Divide by 7

W = 5 * 0.5                             Combine

W = 2.5

H = 4/5 * w

H = 4/5 * 2.5

H = 4 * 0.5

H = 2

Volume

V = L * w * h

V = 3.5 * 2.5 * 2

V = 17.5

Weight

1  Cubic foot Milk = 66.5 pounds

17.5 cubic feet milk = x

1 / 17.5 = 66.5/ x

x = 17.5 * 66.5

x = 1164.75

What is the average rate of change between f (1) and f (5) in the function f (x) = x2 - x - 6 ?
NISA [10]

Answer:

{ \tt{average =  \frac{f(1) + f(5)}{2} }} \\  \\  = { \tt{ \frac{( {1}^{2}  - 1 - 6) + ( {5}^{2} - 5 - 6) }{2} }} \\  =  \frac{ - 6 + 14}{2}  \\  \\  = { \tt{4}}
