Trisha opened a savings account and deposited one-hundred as principal. The account earns 12% interest, compounded annually. What is the balance after 3 years?
Answer: $140.49
Step-by-step explanation:
Trisha opened an account and deposited $100.
The account earns compound interest of 12% yearly and will be on for 3 years.
The formula for compound interest is:
= Principal * ( 1 + rate) ^ time period
= 100 * (1 + 12%)³
= $140.49

∆JKL is an isosceles triangle with vertex angle K. Find the values of x and y if JK = 8x, KL = 13x – 15, m∠KJL=(5y-3)°, and m∠JKL=76°.
Answer:
The values of x and y are x = 3 and y = 11
Step-by-step explanation:
The isosceles triangle has two equal sides in length, and its base angles are equal in measures
In ΔJKL
∵ ΔJKL is an isosceles triangle with vertex K
→ That means the equal sides are JK and KL
∴ JK = KL
∵ JK = 8x and KL = 13x - 15
→ Equate them
∴ 13x - 15 = 8x
→ Add 15 to both sides
∵ 13x - 15 + 15 = 8x + 15
∴ 13x = 8x + 15
→ Subtract 8x from both sides
∵ 13x - 8x = 8x - 8x + 15
∴ 5x = 15
→ Divide both sides by 5 to find x
∴ x = 3
∵ K is the vertex of the ΔJKL
∴ ∠KJL and ∠KLJ are the base angles
∵ The base angles are equal in measures
∴ m∠KJL = m∠KLJ
∵ m∠KJL = 5y - 3
∴ m∠KLJ = 5y - 3
∵ The sum of the measures of the angles of a Δ is 180°
∴ m∠KJL + m∠KLJ + m∠JKL = 180°
∵ m∠JKL = 76°
→ Substitute the measures of the 3 angles in the equation
∴ 5y - 3 + 5y - 3 + 76 = 180
→ Add the like terms on the left side
∵ (5y + 5y) + (76 - 3 - 3) = 180
∴10y + 70 =180
→ Subtract 70 from both sides
∵ 10y + 70 - 70 = 180 - 70
∴ 10y = 110
→ Divide both sides by 10 to find y
∴ y = 11
∴ The values of x and y are x = 3 and y = 11
10% of the passengers on a fly with us airlines flight are in first class. If there are 40 passengers in first class, how many total passengers are on the flight
Answer:
400 passengers
Step-by-step explanation:
To solve the problem, a proportion would be best!
First, let's set up the left side of the proportion. Percents, when used in parts, are always part of 100%, making 100% a whole. We'll use both 10% and 100% as our first fraction, which should look something like this:
[tex]\frac{10p}{100w}[/tex] (with p standing for part and w standing for the whole)
Next, let's set up the right side of our proportion. We'll use the 40 for our part and x for our whole since that is the number we are solving for. The proportion should now look like this:
[tex]\frac{10p}{100w} = \frac{40p}{x}[/tex]
To solve, just cross multiply and divide! Multiply 40 by 100 to give you 4,000. Next, divide 4,000 by the remaining 10 to give you a final answer of 400. If 40 passengers on the flight are in first class, then there are 400 total passengers. Hope this helps!

15=.19(x)+3.78
would you mind giving an explanation? I really need to understand this. thanks!
Answer:
0.59
Step-by-step explanation:
first you have to find x, you do that by getting x by its self. when you do this you do the opposite arithmetic (equation sign like - or +) on both sides of the equal sign. for example since its plus 3.78 you have to subtract 3.78 on both sides of the equal sign, so on so on till you are left with only x on one side of the equal sign

g = price of gym membership for 1 person
Answer:
Step-by-step explanation:
Given in the question:
a) A family paid $96 for 4 pool passes and 2 gym memberships.
b)Later that day , an individual bought pool passes for herself and 2 of her friends, and 1 gym membership for her. She paid $60
Let's write the system of equation for each purchases that happened in the scenario.
Let,
P= Price of each pool passes
G= Price of each gym membership
We get,
a) A family paid $96 for 4 pool passes and 2 gym memberships:
[tex]4P+2G=96[/tex]
b)Later that day , an individual bought pool passes for herself and 2 of her friends, and 1 gym membership for her . She paid $60:
[tex]3P+1G=60\\[/tex]
Therefore, the equation generated in the scenario were:
[tex]4P+2G=96\\3P+1G=60 or 3P+G=60[/tex]
Where,
P= Price of each pool passes
G= Price of each gym membership
