Answer:

58.09 degrees C.

Step-by-step explanation:

T(m)=21+74*10^-0.03m

When m = 10 minutes:

T(10) = 21 + 74*10^(-0.03*10)

= 21 + 74*10^(-0.3)

= 58.0879

Shade of the grid.<br> 4<br> Click and drag to shade.
Sliva [168]

Answer:

I would shade 50 squares

Step-by-step explanation:

"Of" is the same as multiplication so,2/4×100/1=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

2×100/4×1=200/4

Since 200 divided by 4 equals 50 then, 200/4=50

Therefore: 2/4 of 100/1=50
