Margarita [4]

Answer:

Step one:

number of tickets sold

monday=14

tuesday=10

the number of tickets sold for Monday and Tuesday combined is

14+10= 24

step two:

What is the length of AC¯¯¯¯¯ ?
Harman [31]

Answer:

AC = 12.38 cm

Step-by-step explanation:

When there are 2 pairs given, we can use the sine rule to solve the problem.

By pairs we mean "an angle and side opposite to it"

<em>1 pair is 85.2 degree angle and 13 cm, and another pair is 71.6 degree angle and the side AC (which we want to figure out).</em>

<em />

Sine Rule is given by \frac{SinA}{a}=\frac{SinB}{b}

where,

A and B are the two respective angles and a and b are the two respective sides (of the pairs). Plugging all the info and using algebra, we have:

\frac{Sin85.2}{13}=\frac{Sin71.6}{AC}\\AC*Sin85.2=13*Sin71.6\\AC=\frac{13*Sin71.6}{Sin85.2}\\AC=12.38

Thus, AC = 12.38 cm

Amiraneli [1.4K]

Answer:

the simple interest rate is 18.00%

Step-by-step explanation:

The computation of the simple interest rate is shown below:

Amount = Principal × (1 + rate)^years

$4,935 = $3,000 × (1 + rate)^3

After solving it, the rate of percentage is 18.00%

Hence, the simple interest rate is 18.00%
