What is the value of E?
kozerog [31]
Hello!

∠E and the angle measuring 119 degrees (we'll refer to this as ∠A) can be classified as supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees (a straight line). Therefore, we can conclude that sum of ∠E and ∠A is 180 degrees. We can use this information to create the following equation:

∠E + 119 = 180

Now subtract 119 from both sides of the equation:

∠E = 61

We have now proven that ∠E is equal to 61 degrees.

I hope this helps!

Cynthia had a credit card with a 17% APR and a $3,265 balance. She had budgeted to have the credit card paid off in 24 months. B
monitta

Answer:

Cynthia will have to pay $152.16 extra in finance charges.

Step-by-step explanation:

Cynthia had a credit card with a 17% APR and a $3,265 balance.

Cynthia’s credit card company has increased her interest rate to 21%.

Here we have two scenarios, 1st when p = 3265 r = 17% and n = 24

Second when p = p = 3265 r = 21% and n = 24

Scenario 1:

r =17/12/100=0.014166

EMI formula is :

\frac{p\times r\times(1+r)^{n}}{(1+r)^{n}-1}

Putting the values in formula we get;

\frac{3265\times0.014166\times(1+0.014166)^{24}}{(1+0.014166)^{24}-1}

= \frac{3265\times0.014166\times(1.014166)^{24}}{(1.014166)^{24}-1}

EMI = $161.43

Scenario 2:

r = 21/12/100=0.0175

Putting the values in formula we get;

\frac{3265\times0.0175\times(1+0.0175)^{24}}{(1+0.0175)^{24}-1}

= \frac{3265\times0.0175\times(1.0175)^{24}}{(1.0175)^{24}-1}

EMI = $167.77

Now, difference in EMI's = 167.77-161.43=6.34 dollars

And for 24 months this amount becomes = 24\times6.34=152.16 dollars

Therefore, Cynthia will have to pay $152.16 extra in finance charges.

(d) Statement one: Two adult tickets and three children tickets cost $43.00
cricket20 [7]

Answer:

The cost of an adult ticket is $12.50

Step-by-step explanation:

The given information are;

The cost of two adult tickets and three children tickets = $43.00

The cost of one adult ticket and one child ticket = $18.50

Whereby the cost of an adult ticket is represented by <em>x</em> and the cost of a child's ticket is represented by <em>y</em>, we get the following two simultaneous equations;

2·x + 3·y = 43.00...(1)

x + y = 18.5...(2)

(ii) Multiplying equation (2) by 2 and subtracting the result from equation (1) gives;

2·x + 3·y - 2×(x + y) = 43 - 2×18.5 = 6

2·x - 2·x + 3·y - 2·y = 0 + y = 6

∴ y = 6

The cost of each the children ticket = $6.00

From equation (2), where y = 6, we get;

x + y = 18.5

∴ x + 6 = 18.5

x = 18.5 - 6 = 12.5

The cost of an adult ticket, x = $12.50.
