Answer:

95

Step-by-step explanation:

let x be his mark in the fourth test, then

mean = \frac{83+81+73+x}{4} = 83 ( multiply both sides by 4 )

83 + 81 + 73 + x = 332

237 + x = 332 ( subtract 237 from both sides )

x = 95

Scott is ordering 6 bags of cat food from canada. each bag has a mass of . to determine the shipping costs, scott needs to know
OLEGan [10]

The weight of the cat food in pounds is 99 lbs.

<h3>What is a pound?</h3>

The pound, sometimes known as pound-mass, is a unit of mass that is used in both the British imperial and American customary measurement systems.

<h3>How do we convert kg to pounds?</h3>

You multiply a weight by the conversion factor 2.2046 to change a mass measurement from kilograms (kg) to pounds (lbs).

Given that,

Mass of each bag = 7.5 Kg.

Number of bags bought = 6

Firstly, we need to find how much the cat food weighs:

Total weight of cat food = 6 × 7.5

Total weight of cat food = 45kg

Next, we will require to convert the kg into pounds:

1kg = 2.2lb

45 kg = 45* 2.2

45 kg = 99 lbs

Therefore, the weight of the cat food in pounds id 99lbs.

Do the graphs of 4y=(x-3)^2 and 3x-y=14 intersect at (5,1)
AfilCa [17]

Answer:

it will happen if both y and x components be equal

so

y= (x-3)²/4 , y = 3x- 14

3x - 14 = (x-3)²/4

12x - 56 = x²-6x + 9

x² - 18x + 65 = 0

delta = 18²-4*65 = 64

x1 = (18 + (64)^(1/2))/2 = 13

x2 = (18 - (64)^(1/2))/2 = 5

one point is x = 5 but we should check if on that point y component is 1 or not

y = (5-3)²/4 = 1

so the functions will intersect at (5,1)
