Two angles of a triangle are the same
size. The third angle is 12 degrees
smaller than the first angle. Find the
meone the ongles
Let the measure of the first angle be = x
Let the measure of the second angle = x
Then , the measure of the third angle = x - 12
Let us find the value of all of these angles using the angle sum property .
Sum of all angles inside a triangle = 180°
[tex]x + x + x - 12 = 180[/tex]
[tex]3x - 12 = 180[/tex]
[tex]3x = 180 + 12[/tex]
[tex]3x = 192[/tex]
[tex]x = \frac{192}{3} [/tex]
[tex]x = 64[/tex]
Which means :-[tex]measure \: of \: the \: first \: angle = x = 64°[/tex]
[tex]measure \: of \: second \: angle \: = 64°[/tex]
[tex]measure \: of \: the \: third \: angle \: = x - 12 = 64 - 12= 52°[/tex]
∴ The measure of the first angle = 64° , the measure of the second angle = 64° and the measure of the third angle = 52° .

The expression 3y−24 factored using the GCF is
Answer:
the answer is y equals 8
Answer:
y - 8
Step-by-step explanation:
All you need to do is find the GCF.
First you line up all of the factors and then find the common factor that is the biggest you can find.
3 : 1, 3
24 : 1, 2, 3, 4, 6, 8, 12, 24
Once you find the GCF then you can divide them by it,
3/3 = 1
24/8 = 8
Then you turn the one into y.

What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The bicycle tend to need repairs periodically, but you tend to take good care of them overall.
Every bicycle has a useful product lifespan. This limited warranty is not meant to suggest or imply that the frame or components can never be broken or will last forever.
This limited warranty covers manufacturing defects that occur within the normal lifespan and use of the product.
Hence we can conclude that the kind of warranty would be a good one to purchase is option (B) limited warranty is the correct answer.

On a six-day vacation, the forecast is a 70% chance of rain every day. What’s the probability that it rains every day?
Answer:
0.12 (12%)
Step-by-step explanation:
Step 1: Given data
Probability of rain every day: 70% (0.7)
Step 2: Calculate the probability that it rains every day
The probability that it rains one day is independent of the probability that it rains another day. For independent events, we can calculate the probability that it rains every day by multiplying the individual probabilities. Since the individual probabilities are equal, this is the same as raising the individual probability to the number of days.
P = 0.7⁶ = 0.12

Ana María had $28,000 to invest. She divided the money into three different accounts. At the end of the year, she had made $1,160 in interest. The annual yield on each of the three accounts was 3.5%, 4.25% and 4.75%. The amount of money in the 4.75% account was 75% of the amount of money in the 3.5% account. Define variables and write systems of equations to represent the situation. Solve the system to determine how much was put into each account.
Answer:
x + y + z = 28,000
0.035x + 0.0425y + 0.0475z = 1160
z = 0.75x
Step-by-step explanation:
Let x = amount invested at 3.5%.
Let y = amount invested at 4.25%.
Let z = amount invested at 4.75%.
The total amount is $28,000.
Equation 1:
x + y + z = 28,000
The total interest is $1,160.
Equation 2:
0.035x + 0.0425y + 0.0475z = 1160
"The amount of money in the 4.75% account was 75% of the
amount of money in the 3.5% account."
Equation 3:
z = 0.75x
The system of equations is:
x + y + z = 28,000
0.035x + 0.0425y + 0.0475z = 1160
z = 0.75x
Answers to the system of equations:
The total amount in each account is:
x = $8,000
y = $14,000
z = $6,000

What would be the bill amount of an article costing
Rs.350. if 15% VAT is levied after a discount of 20%?
plz put your bank account number also if answer is right money of $10 will be send
Answer:
$322
Step-by-step explanation:
Given parameters:
Cost price = Rs. 350
VAT = 15%
Discount = 20%
Unknown:
Bill amount = ?
Solution:
Since the discount was first applied to the cost price, let us find the now discounted price of the article;
Discount = percent discount x cost price
Discount = [tex]\frac{20}{100}[/tex] x 350 = $70
So, new selling price = $350 - $70 = $280
Now, the VAT is 15%;
So, VAT amount = [tex]\frac{15}{100}[/tex] x 280 = $42
The bill amount = $280 + $42 = $322
find the nth term in the sequence 7/8, 3/4, 9/14
Given parameters:
Terms of the sequence = 7/8 , 3/4 , 9/14
From terms, we know that our first term is [tex]\frac{7}{8}[/tex]
We need find either of the common difference or the common ratio of this sequence.
For this, the common ratio is applicable.
Common ratio = [tex]\frac{3}{4} / \frac{7}{8}[/tex]
This is the factor by which when we multiply the subsequent terms with results into them;
Solving the above gives [tex]\frac{6}{7}[/tex]
The common ratio is 6/7.
To find the nth of this sequence we apply the formula below;
A[tex]_{n}[/tex] = Arⁿ⁻¹
Aₙ is the term we are looking for
A is the first term of the sequence
r is the common ratio
n is the position of the term
So for any nth term in this sequence;
Aₙ = [tex]\frac{7}{8}[/tex] x [tex]\frac{6}{7}[/tex] ⁿ⁻¹
We can use the above solution to find any term in the sequence.
