Answer: 35 t shirts
Step-by-step explanation:
Let number of t shirts be x
Let profit made be y
On main street, the store costs $650,
Selling the t shirt at $32 per 1
He would make a revenue of 32x
Profit = revenue - cost accrued
y1 = 32x - 650
On Broad street, the store costs $440,
Selling the t shirt at $26 per 1
He would make a revenue of 26x
Profit = revenue - cost accrued
y2 = 26x - 440
To make same profit on either location
y1 = y2
32x - 650 =26x - 440
32x -26x = -440+650
6x = 210
x = 210/6
= 35 t shirts
Answer:
6/5 or 1 1/5
Edit:
soo
= 
since they both are being multipled to the square root of 5, you can just add them (i think)
Step-by-step explanation:
6 times the square root of 5
you add 4 and 2
Answer:
(a) 13536.10J
(b) 27072.20J
Step-by-step explanation:
(a) Height of tank (h) = 4 feet = 4/3.2808 = 1.22m
Volume of water in full tank = 4ft×5ft×4ft = 80ft^3
Volume of water in half tank = 1/2 × 80ft^3 = 40ft^3
Density of water = 62.4lb/ft^3
Mass of water = density × volume = 62.4 × 40 = 2496lb = 2496×0.45359kg = 1132.16kg
Work done to empty half of the tank = mgh = 1132.16×9.8×1.22 = 13536.10J
(b) Work done to empty all of the tank = 2 × work done to empty half of the tank= 2 × 13536.10J = 27072.20J
Answer:
Step-by-step explanation:
( g ° f )(x) = ( x + 7 )² = x² + 14x + 49
20 + 3(x² + 14x + 49) = - 34
20 + 3x² + 42x + 147 = - 34
3x² + 42x + 201 = 0 ⇔ x² + 14x + 67 = 0
D = 196 - 268 = - 72 < 0
