B
Based on the given information, what is the measure of the missing length, c?
Enter your answer as a number like this: 42.
12
Answer:
5
Step-by-step explanation:
We will use the Pythagorean theorem to solve this problem. We know [tex]a^{2} + b^{2} = c^{2}[/tex]. (a, in this case, will be c) Now, we can substitute in our numbers, giving us:
[tex]a^{2} + 12^{2} = 13^{2}[/tex]
Simplifying:
[tex]a^{2} + 144 = 169[/tex]
Subtract 144 from both sides gives us:
[tex]a^{2} = 25[/tex]
Square rooting both sides gives us:
[tex]a = 5[/tex]
So, the missing measurement (c) is 5.

Arianys invests money in an account paying a simple interest of 3% per year. If m
represents the amount of money she invests, which expression represents her balance
after a year, assuming she makes no additional withdrawals or deposits?
Adrian must multiply his money by 1.03 to find his total balance in a year in one step.
What is simple interest?Borrowers must pay simple interest to lenders as a fee for a loan. Compound interest is not taken into account while calculating it; just the principal is used. Simple interest is applicable to all loans. It is also the form of interest that banks give their customers on their savings accounts. There are two techniques to compute interest: simple interest and compound interest. The principal, or initial amount of a loan, is used to compute simple interest. Compound interest, sometimes known as "interest on interest," is calculated using both the original amount and the total accumulated interest from prior periods.The following calculation must be done in order to determine what Adrian should multiply his current balance by in order to find his total balance in a year in one step, assuming that no money will be added to or subtracted from the investment. Adrian invests money in an account that offers simple interest of 3% per year.
Current balance = X
Interest = 3% = 3/100 = 0.03
Interest + principal = 1.03
1.03X = Total balance in a year
Therefore, Adrian must multiply his money by 1.03 to find his total balance in a year in one step.

The triangles are similar.
What is the value of x?
Enter your answer in the box.
Answer:
x = 4
Step-by-step explanation:
We can look at the hypotenuse of both the triangles to find the factor that we multiply by. (In similar triangles, corresponding sides are always in the same ratio)
Big triangle:little triangle
25:5
5:1
So, we have to multiply the corresponding side of the little triangle by 5 to get an equivalent value.
Solve for x:
3x+8 = 4(5) [ratio!!]
3x+8 = 20
(subtract 8 from both sides)
3x = 12
(divide both sides by 3)
x = 4
Thus, we have our answer!

The cost of 3 dozen oranges is rupee 54 how many oranges can be purchased for rupee 24 ?
Can you explain the steps plsss it’s for my assignment
Answer:
You can buy 17 oranges for rupee 24.
Step-by-step explanation:
3 dozen = 3 x 12 = 39 oranges
54 ÷ 39 = 1.38461538462
1 orange = rupee 1.38
1.38461538462 x 17 = 23.5384615385
17 oranges = rupee 23.54
If you add the cost of 1 more orange it would cost more than rupee 24 so you can only buy 17 oranges for rupee 24.

4) If $8000 is deposited into an account earning compound interest at an annual interest rate of 4% for 10 years, and it is compounded quarterly (thus 4 times per year), how much money is in the account at the end of the 5 years? Round your answer to the nearest cent. Show you work.
5) For problem #4, how much interest was earned? Show you work.
Answer:
The amount of money in the account at the end of 5 years is $9,841.63.
Step-by-step explanation:
The compound interest formula is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate (expressed as a decimal), n is the number of times interest is compounded per year, and t is the number of years.
In this case, P = 8000, r = 0.04, n = 4 (because interest is compounded quarterly), and t = 5 (because we are trying to find the balance after 5 years).
So the formula becomes:
A = 8000(1 + 0.04/4)^(4*5)
By plugging the number into the formula we can find the final amount after 5 years
A = $9,841.63
The amount of money in the account at the end of 5 years is $10,404.69, and the interest earned is $2404.69.
Explanation:To calculate the amount of money in the account at the end of 5 years, we need to use the compound interest formula: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
Substituting the given values into the formula, we have A = 8000(1 + 0.04/4)^(4*5).Simplifying this equation gives us A = 8000(1 + 0.01)^20.Calculating this equation results in A = 8000 * 1.01^20 = $10,404.69 (rounded to the nearest cent).To calculate the amount of interest earned, we subtract the initial deposit from the final amount: interest = A - P.
Substituting the given values into the equation, we have interest = $10,404.69 - $8000 = $2404.69 (rounded to the nearest cent).Learn more about interest here:https://brainly.com/question/14295570

A linear function has the table of values shown. The information in the table shows the number of tickets sold on opening night of a movie as a function of the number of hours since the tickets have been on sale
The equation that represents the linear function is y =32x
What is a linear equation explain?
An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.
The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.
A linear function is represented as
y = mx + c
The slope is calculated as
m = y₂ - y₁/x₂ - x₁
m = 576 - 64/18 - 2
m = 512/16
m = 32
The linear equation is then calculated as
y = 32( x - 2 ) + 64
y = 32x - 64 + 64
y = 32x

Kyle is curious on how long does it take for him to reach school from their house. With that he asked his parents what is their speed as they drive going to school. How long does it take for kyle to reach school if their speed is in constant 40 km/h as they travel 60 km going to school in the northern side of their city? Show your solution.
math/science..
Answer: To find how long it takes Kyle to reach school, we can use the formula:
Time = Distance / Speed
Given that Kyle's parents travel at a constant speed of 40 km/h and the distance from their house to school is 60 km, we can substitute these values into the formula:
Time = Distance / Speed = 60 km / 40 km/h
To convert the answer from hours to minutes we have to multiply the result by 60.
Time = (60 km / 40 km/h) * 60 = 1.5 * 60 = 90 minutes
So it takes Kyle 90 minutes to reach school from their house if their speed is constant at 40 km/h and the distance they are traveling is 60 km.

b. -2
What is an imaginary number?An imaginary number is a number which is obtained by finding the square root of a negative number.
The specified expression is; [tex]\frac{x+2\cdot \mathbf{i}}{1 + \mathbf{i}}[/tex]
Multiplying the numerator and the denominator by the complex conjugate of the denominator, (1 - i), we get;
[tex]\frac{x+2\cdot \mathbf{i}}{1 + \mathbf{i}}\times \frac{1 - \mathbf{i}}{1 - \mathbf{i}} =\frac{x - x \cdot \mathbf{i}+2 \cdot \mathbf{i}-2\cdot \mathbf{i}^2}{1 - \mathbf{i}^2}[/tex]
[tex]\frac{x - x \cdot \mathbf{i}+2 \cdot \mathbf{i}-2\cdot \mathbf{i}^2}{1 - \mathbf{i}^2} = \frac{x + (2 - x)\cdot \mathbf{i} + 2}{1 - (-1)} =\frac{x + (2 - x)\cdot \mathbf{i} + 2}{2}[/tex]
Where x is real, for the number to be purely an imaginary number, we get;
[tex]\dfrac{x + (2 - x)\cdot \mathbf{i} + 2}{2} = \dfrac{x +2+ (2 - x)\cdot \mathbf{i} }{2} = \dfrac{0+ (2 - x)\cdot \mathbf{i} }{2}[/tex]
[tex]\frac{0+ (2 - x)\cdot \mathbf{i} }{2} = \frac{(2 - x)\cdot \mathbf{i} }{2} = \frac{(2-x)}{2} \cdot \mathbf{i}[/tex]
Therefore, for the number to be a purely imaginary number, then; x + 2 in the numerator following the multiplication of the numerator and the denominator by the complex conjugate of 1 + i, which is 1 - i, should be 0, and we get;
x + 2 = 0
x = 0 - 2 = -2
x = -2
The value of x such that the expression (x + 2·i)/(1 + i) is a purely imaginary number is; x = -2
