Theo ate .7 of his candy bar. How many more tenths must he eat to finish the whole candy bar?

3 tenths

Step-by-step explanation:

One candy bar

= 1 candy bar

= 1.0, or 10 tenths (one tenth is 0.1)

If Theo eats 0.7 of a candy bar, we know that

1.0 - 0.7 = 0.3

0.3 = 3 *0.1 (one tenth)

Therefore, the answer is 3 tenths.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer4 to the second power is 16

and 4 to the third power is 64,
