Answer:
25 students
Step-by-step explanation:
Let x represent the amount of students in the astronomy club then:
80%x=20
Convert 80% to a fraction. Any percentage is that number over 100:
[tex]\frac{80}{100}x=20[/tex]
Simplify the fraction:
[tex]\frac{8}{10}x=20[/tex]
[tex]\frac{4}{5}x=20[/tex]
Multiply both sides by 5:
[tex]4x=100[/tex]
Divide both sides by 4:
[tex]x=25[/tex]
There are 25 students in the astronomy club.

Please select the best answer from the choices provided A B C D.
Assets are the resources owned by any individual or organization. Svenson's assets increased by $1,400.
What is an asset?An asset is any resource that is been owned by a company, organization, or individual.
Given to us
The original price of the refrigerator is $2,300.
The Market price of the refrigerator is $1,900.
Svensons' paid $500
As it is given to us that the Market price of the refrigerator is $1,400 and as the Svenson's has bought the refrigerator, therefore, this resource(refrigerator) is now owned by the Svenson.
We know that the down payment made is also made from our assets(cash). therefore, the assets increased by $1,400($1900-$500)only.
Thus, the Svensons’ assets increased by $1,400.

85% are green. At the end of each class, she mixes the cards, reaches inside the bag, and draws out one card at
random. If a red card is drawn, the students will not be assigned homework. She shows the class the card, and
then places the card back in the bag. Carla would like to carry out a simulation to estimate the number of days it
will take in order to get a "no homework" day. She assigns the digits to the outcomes.

Alexandra bought a $315,000.00 house, paying 10% down, and financing the rest at 6% interest for 20
years.
A. What is the monthly payment?
Alexandra has a payment of
a month.
B. How much interest will be paid over the life of the loan?
Alexandra will pay
in interest over the life of the loan.
Answer:
A. payment: $2031.08
B. interest: $203,959.20
Step-by-step explanation:
There are many financial calculators, apps, and spreadsheets that will solve this for you. Here, we will use the amortization formula that would be implemented by one of those.
A.The monthly payment is given by ...
A = P(r/12)/(1 -(1 +r/12)^(-12t)) . . . loan of P at rate r for t years
If 10% is put down on the house, then amount that needs to be financed will be ...
$315,000 × (1 -10%) = 0.90 × $315,000 = $283,500
For interest rate 6% and a period of 20 years, the monthly payment is ...
A = $283,500(0.06/12)/(1 -(1 +0.06/12)^(-12·20))
A = $283,500(0.005)(1 -(1.005^-240)) ≈ $2,031.08
__
B.The interest is the difference between the amount repaid and the original loan value:
interest = 240 × $2031.08 - 283,500 = $487,459.20 -283,500
interest = $203,959.20
Select any equations that have the same solution set as:
2x + 3 = 13
A.6 + 4x = 26
B.10x = 20
C.12 = 13 - 5x
D.4x = 20
Answer: 6+4x=26, 4x=20
Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.
If you solve the equation, 2x+3=13 (subtract 3 from both sides)
2x=10 (divide both sides by 2)
x equals 5.
if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.
How do I find the surface area of 2 and 3 Plss helpppp
HELP Solve for x and y
Answer:
X = 12 / Y = 49
Step-by-step explanation:
X = 12
This is because one of those angles is a 90 degree angle, and the other is 78; After subtracting them both from 180, you're left with 12
Y= 49
I did the same procedure as above. The two far left lines are equal, which means 41 is also an angle on the other side. 180 - 90 - 41 = 49
Mark cast a shadow that is 4 feet long. At the same time, a nearby tree casts a shadow that is 20 feet long. If mark is 6 feet tall, how tall is the tree?
Answer:
30 ft
Step-by-step explanation:
We can use the given information to set up a ratio...
[tex]\frac{Mark's\ height}{Mark's\ shadow}=\frac{Tree's\ height}{Tree's\ shadow}[/tex]
[tex]\frac{6\ ft}{4\ ft}=\frac{x}{20\ ft}[/tex]
We can solve this ratio using cross multiplication (multiply the numerator of the first fraction by the denominator of the second and the numerator of the second fraction by the denominator of the first):
120 = 4x
Divide both sides by 4
x=30 ft
Molly is traveling from France to the US.She knows that 1 US dollar is worth $0.80 Euro.How much is 350 Euros worth is USD?
Answer:
437.5 USD
Step-by-step explanation:
350/.8*1=437.5
The value of 350 euros will be equal to 437.5 USD.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Molly is traveling from France to the US. She knows that 1 US dollar is worth $0.80 Euro.
The value of 350 euros in USD will be calculated as,
1 US dollar ⇒ 0.80 Euros
1 Euros ⇒ 1 / 0.80 dollar
350 Euros ⇒ ( 350 / 0.80 ) dollars
350 Euros ⇒ 437.5 dollars
Therefore, the value of 350 euros will be equal to 437.5 USD.
