kirill [66]

Answer:

6t = -21

Step-by-step explanation:

3t-7 = 5t simplifies by subtracting 5t on both sides, then adding 7 on both sides:

umka2103 [35]

Answer:

0.5158

Step-by-step explanation:

The exponential decay of a given material is used to describe the process by which a material decreases in size and amount over a specific period of time. The material will decay with respect to its decay factor. Therefore, if the 10-hour decay factor is approximately 0.2661, the 5-hour growth/decay factor will be: (0.2661)^(5/10) = (0.2661)^0.5 = 0.5158.

Alborosie

Answer: 75

Step-by-step explanation:

Step-by-step explanation:

In order to cover his backyard with sod, he needs to cover the area of the backyard.

His backyard is a rectangle, and area of a rectangle represented by A is given as l*w

Where,

is the length, and

is the width

So, the area of Jim's backyard is square yards.

l*w=12/5/6*10/2/5=2002/15 or 133.466

The area of each sods are solved using the area of the rectangle formula.

l*w=1/1/3*1/1/3=16/9

To find HOW MANY of these sods we would need to cover the whole backyard, we divide the backyard area by each sod area:

=2002/15 divided by 16 /9=3003/40or 75.075

Since, fractional sods can't be bought, Jim has to buy 75 sods approximately .
