From 60 cm to 90cm.
% i need help
Answer:
90 is 150% of 60
OR
90 is 50% greater than 60
Step-by-step explanation:
To find the percentage increase between two values, the first step is to find the difference between the final and initial value.
Final value: 90cm
Initial value: 60cm
Difference = 90 - 60 = 30cm
Next, you need to divide the difference between the two values by the initial value.
30 / 60 = 0.5
Lastly, you need to take the value previously found and multiply it by 100 to convert it from a decimal to a percentage.
0.5 * 100 = 50%
This value will be your percentage increase.
If you want to know what percentage the final value is of the initial value, you can take the percentage you have and add 100% to it.
50% + 100% = 150%
If this answer helped you, please leave a thanks or a Brainliest!!!
Have a GREAT day!!!
Answer: 150%
Step-by-step explanation:
First, ask yourself what the difference between the two is: 90-60=30.
Secondly, 30 is 1/2 of 60. 1/2=50%.
You also need to add the hundred percent because we are adding 60 and 60 is 100% of 60. It increases by 50 and then 100. so 150%.
50% + 100% = 150%

A utility cooperative is a specific kind of cooperative that is responsible for providing its members with a public utility, such as power, water, or telecommunications. Profits are either distributed to members as "patronage" or "capital credits," which are dividends paid on a member's investment in the cooperative, or they are reinvested for infrastructure.
Every consumer is a shareholder and a member of the company. This means that, in contrast to investor-owned utilities where the amount of individual authority is determined by the number of shares held, all members have the same level of personal authority. Many utility cooperatives operate their business in accordance with a set of ideals based on the Rochdale Principles, just like cooperatives active in other industries.

The equation for your savings account can be represented as:
y = 50 + 10x
The equation for your friend's savings account can be represented as:
y = 25 + 10x
where x is the number of weeks and y is the total amount of money in the account.
Savings Account EquationsThe equation for the savings account can be determined by taking the initial amount of money and adding the weekly deposit over a certain number of weeks. The initial amount of money in your savings account is $50, and you plan to deposit $10 each week, so each week your balance will increase by $10.
Starting from the initial balance, after the first week, the balance will be $50 + $10 = $60. After the second week, the balance will be $60 + $10 = $70, and so on. We can represent this pattern using an equation:
y = 50 + 10x
where y is the balance after x number of weeks.
Similarly, for your friend's savings account, the initial balance is $25 and the weekly deposit is $10. So, each week the balance will increase by $10. Using the same pattern, the equation for your friend's savings account can be represented as:
y = 25 + 10x

What is a circle ?All points on a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.
The following are some of the circle's crucial characteristics:
If the circles have equal radii, they are said to be congruent.The longest chord in a circle is its diameter.In the center of a circle, equal chords subtend equal angles.The chord is divided in half by the radius drawn perpendicular to the chord.Circles with various radii are comparable.A circle can encircle a kite, triangle, square, trapezium, rectangle, and more.You may encircle a square, triangle, or kite with a circle.Equal in length are the chords that are equally spaced from the center.The longest chord's (diameter) distance from the circle's center is equal to zero.As the chord length rises, the perpendicular distance from the circle's center decreases.The tangents are parallel to one another if they are drawn at the diameter's end.The radii connecting the ends of a chord to the center of a circle create an isosceles triangle.The radius of the circle is 3 miles

The value of k = −8 for which AB = BA.
[tex]A = \left[\begin{array}{ccc}2&3\\-1&1\end{array}\right][/tex]
[tex]B = \left[\begin{array}{ccc}1&9\\-3&k\end{array}\right][/tex]
Now,
[tex]AB = \left[\begin{array}{ccc}2&3\\-1&1\end{array}\right] \left[\begin{array}{ccc}1&9\\-3&k\end{array}\right] = \left[\begin{array}{ccc}-7&18+3k\\2&-9-k\end{array}\right][/tex]
[tex]BA = \left[\begin{array}{ccc}1&9\\-3&k\end{array}\right] \left[\begin{array}{ccc}2&3\\-1&-1\end{array}\right] = \left[\begin{array}{ccc}-7&-6\\-6-k&-9-k\end{array}\right][/tex]
Thus, in order for AB = BA, we must have that
[tex]\left[\begin{array}{ccc}-7&18+3k\\2&-9-k\end{array}\right] = \left[\begin{array}{ccc}-7&-6\\-6-k&-9-k\end{array}\right][/tex]
Equate the values, and we get
18 + 3k = -6
3k = -6 - 18
3k = -24
k = -8
and 2 = -6 - k
k = -6 - 2
k = -8
Therefore we can say that it is easy to see that these equations are satisfied if and only if k = −8, and thus k = −8 is the (unique) value for which AB = BA.

If 29 student tickets were sold, then all possible values for the number of adult tickets that the drama club must sell in order to meet the show's expenses are 54 and 55 .
the price for each student ticket is $4.50 and adult is $8 ;
The number of people auditorium can hold is = no more than 84 people ;
the number of children tickets sold is = 29 tickets ;
Let "x" be number of adult tickets sold.
The total revenue from ticket sales = $4.50×29 + $8×(x)
⇒ $130.5 + $8x.
The total revenue must be at least $560,
So , $130.5 + $8x ≥ $560.
Subtracting $130.5 from both sides, we get $8x ≥ $429.5 ;
Dividing both sides by 8, we get x ≥ 53.69 ;
Since the number of adult tickets sold must be an integer, the minimum number of adult tickets that must be sold is 54.
The maximum number of people allowed in the auditorium is 84, so the maximum number of adult tickets that can be sold is 84 - 29 = 55.
Therefore, the possible values for the number of adult tickets that must be sold are 54, 55.

How much would $400 be worth after 6 years, if it were invested at 2%
interest compounded annually? (Use the formula below and round your
answer to the nearest cent.)
If $450.46 were invested at 2% interest that is compounded annually, it would be worth after 6 years.
How is annual compound interest determined?The future value of a loan or investment may be determined using the formula FV = P*(1+R/N)(N*T), where FV is the future value, P is the original principal, R is the annual interest rate, N is the number of times interest is compounded annually, and T is the amount of time in years.
The formula to use isA = P(1+r/n)ⁿ
From the question, we have
P = $400
t = 6 year
r = 2%
r = 0.02
n = 1
Using the parameters, we haveA = P(1+r/n)ⁿ
A = 400(1+0.02/1)⁶
A = 400(1.02)⁶
A = $450.46.
