Answer:

The answer is A

Step-by-step explanation:

Express the number in scientific notation as real numbers:

9.4 \times  {10}^{ - 8}  = 0.000000094 \\ 9.25 \times  {10}^{ - 6}  = 0.00000925 \\ 2.5 \times  {10}^{3}  = 2500 \\ 7 \times  {10}^{3}  = 7000

So, from least to greatest;

0.000000094 - 0.00000925 - 2500 - 7000

9.4 x 10^-8, 9.25 x 10^-6, 2.5 x 10^3, 7 x 10^3 (first option)

If a spring stretches 6 meters when a 7-kilogram weight is attached to it, how much will it stretch when a 42-kilogram weight is
Zinaida [17]

Answer:

Step-by-step explanation:

 This is a simple proportion problems.

7 kilogram weight attache to a spring stretches  = 6 meters

 1 kilogram would stretch                                       =  6/7 m

Therefore 42 kilograms would  stretch                  = (6/7 x 42)meters

                                                                                 =  36 meters.

Help me plz i dont understand how t=40​
timama [110]

Answer:

t=40

Step-by-step explanation:

The sum of all angles in a triangle will always equal 180°. This means that:

(2t-42)+(4t-49)+(2t-49) = 180°

Let's solve this equation!

(2t-42)+(4t-49)+(2t-49) = 180

First we simplify what's on the left side:

2t-42+4t-49+2t-49 = 180

2t+4t+2t-42-49-49 = 180

8t-140 = 180

*Add 140 to both sides

8t = 180+140

8t = 320

Divide both sides by 8 to know what t means:

t = 320/8

t = 40
