What is the arc measure of YWZ in<br> degrees?<br> (5w+4)<br> (11w)

Rashid [163]

Answer:

59 degrees

Step-by-step explanation:

In the figure below, XZ is a diameter of circle A.

Since the Angles (5w+4) and (11w) forms a straight line, then:

$(5w+4)^\circ+(11w)^\circ=180^\circ\\5w+11w+4=180\\16w=180-4\\16w=176\\w=\frac{176}{16}\\ w=11$

Therefore, the arc measure of YZ will be:

$5w+4=5*11+4=59^\circ$

A student has a savings account earning 3% simple interest. She must pay $1200 for first-semester tuition by September 1 and $12

Bingel [31]

Using simple interest, it is found that she needs to earn $2,391.07 during the summer.

<h3>Simple Interest</h3>

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

A(t) = A(0)(1 + rt)

In which:

A(0) is the initial amount.

r is the interest rate, as a decimal.

For this problem, the objective is to have <u>$1200 in 3 months = 0.25 years</u>, hence the parameters are given as follows:

A(0.25) = 1200, t = 0.25, r = 0.03.

Hence we have to solve for A(0):

A(0)(1 + 0.03 x 0.25) = 1200

A(0) = 1200/(1 + 0.03 x 0.25)

A(0) = $1,191.07.

She also needs to earn $1,200 to pay the first-semester bill on time, hence:

1200 + 1191.07 = $2,391.07.

She needs to earn $2,391.07 during the summer.

Using the two way table(in pic) what percentage of the students that do NOT like to travel out of state like camping? Round to t

kramer

Using it's concept, it is found that the percentage of the students that do NOT like to travel out of state that like camping is:

B. 34%.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$

In this problem, there are 112 students that do not like traveling out of the state, and of those, 38 like camping, hence the percentage is:

$P = \frac{38}{112} \times 100\% = 34\%$

Hence option B is correct.
