Answer:

  His estimate is somewhat low.

Step-by-step explanation:

The total bill is $9.50 +3.50 = $13.00. The estimated tip is 15% of $10, so Jamal needs to add 15% of $3, or $0.45, to his estimate to leave a tip equal to 15% of the bill.

The tip Jamal has calculated is about 11.5% of the bill. (1.50/13.00 ≈ 0.1154)

The tip Jamal wants to leave is $1.95. (0.15·13.00 = 1.95)

Convert the following radian angle into degrees.
NeTakaya

The degree of the radian angle 0.11 is 6.3^{\circ}

Explanation:

It is given that the radian angle is 0.11

We need to determine the degrees of the radian angle.

To convert the radian into degrees, let us multiply the radian with \left(\frac{180}{\pi}\right)

Thus, we have,

0.11\times\left(\frac{180}{\pi}\right)=\frac{19.8}{\pi}

It is given that \pi=3.14

Substituting \pi=3.14 in the above expression, we have,

\frac{19.8}{3.14} =6.303...

Rounding off to the nearest tenth, we have,

6.3^{\circ}

Thus, the degree of the radian angle 0.11 is 6.3^{\circ}
