You want to replace the s with 150 in the equation and then just solve for t.
150=16√7t +62    subtract 62 from both sides
88=16√7t              divide both sides by 16
5.5=√7t                to get rid of the square root  square both sides. 
30.25=7t              now divide both sides by 7
4.3 = t (approximately) 
so at 4 weeks they will have sold 150 units.

1 The legs of a triangle are 6 cm and 8 cm. The hypotenuse is 14 cm. Is it a right triangle?
Vitek1552 [10]

Answer:

this is not a right triangle

Step-by-step explanation:

^  = squared

The formula forthe Pythagorean theorem is    a^+ b^   = c^

If this is a right triangle this must be true

6^ +    8^   =   14^

36 + 64 =  196

100  is not equal to 196

So this is not a right triangle

The volume inside a rectangular storage room is 2,106 cubic feet. The room is 9 feet high. Find the area of the floor.
hichkok12 [17]

Answer:

Area of the floor is 234 feet²

Step-by-step explanation:

To find the area of the floor of a rectangular storage room that is 2,106 cubic feet and has a height of 9 feet , we will follow the steps below;

First, write down the formula for calculating its volume

volume = l×b×h

but area=l×b

volume = area × h

From the question given volume =  2106 cubic feet

height h = 9 feet

volume = area × h

2106 = area ×  9

Divide both-side of the equation by 9

2106/9 = area ×  9/9

234 = area

area = 234 feet²

Area of the floor is 234 feet²
