The interest rate for Rebeka's account is 5%.
What is the meaning of interest rate?
The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.
Given that, Rebeka deposits $1500. She earn $131.25 as interest after 21 months.
The formula of simple interest is
I = PRT
I = interest
P = Principal
R = Rate of interest
T = time
In the given question,
P = $1500
I = $131.25
T = 21 months = 21/12 years.
Putting P = $1500, I = $131.25, T = 21/12 years in I = PRT:
131.25 = 1500 × R × (21/12)
Divide both sides by 1500 × (21/12):
R = 131.25 /[1500 × (21/12)]
R = [131.25 × 12] /[1500 × 21]
R = 0.05
R = 5%

Answers
The point F( – 4, – 1) i rotated 270° counterclockwie around the origin. then The coordinates of the point F' is (-1 ,4 )
Given that the point J(-2,1) is rotated about 270° about the origin.
Coordinates of the resulting point F':
Since, we know that, when rotating a point 270° counterclockwise about the origin, the point (x,y) becomes (y,-x) which means we switch the places of x and y coordinates and make x as negative.
Therefore, the transformation is given by
(x ,y) -> ( y , -x)
Using the above transformation, we have,
(-4 ,-1) ⇒ ( -1 , -(-4)) ⇒ (-1 , 4)
Therefore, the resulting point of the coordinates of the point F' is (-1 ,4)

Casho has a points card for a movie theater. She receives 55 rewards points just for signing up. She earns 2.5 points for each visit to the movie theater. She needs at least 90 points for a free movie ticket. Use the drop-down menu below to write an inequality representing v, the number of visits she needs to make in order to get a free movie ticket.
Answers
Answer: She need 14 visits to reach 90 points
Step-by-step explanation:
Let y be the number of points and v be the number of visits
We will have an equation
y= 2.5v + 55
Now we want to find the number of visits she needs to reach 90 points; we put 90 in the y.
90 = 2.5v +55
Subtracted 55 from both sides
35 = 2.5v
Divided both sides by 2.5
v= 14 visits
So she need 14 visits to reach 90 points

Answers
Answer:
The possible values of t for which the rocket's height is 12 meters are approximately 1.1 or -1.1.
Step-by-step explanation:
The height of the rocket after t seconds is given by the equationh = 35t - 5t^2.To find the values of t for which the rocket's height is 12 meters, we can set the height equal to 12 and solve for t
12 = 35t - 5t^2
t = (-b ± √(b^2 - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation. In this case, a = -5, b = 35, and c = -12.Plugging these values into the quadratic formula, we gett = (35 ± √(35^2 - 4(-5)(-12))) / 2(-5)
t = (35 ± √(35^2 + 240)) / -10
t = (35 ± √575) / -10
This gives us two possible values fort = (35 + √575) / -10 = (35 + 24) / -10 = 11/10 = 1.1
t = (35 - √575) / -10 = (35 - 24) / -10 = -11/10 = -1.1
Therefore, the rocket's height is 12 meters when t is approximately 1.1 or -1.1.The rocket's height is 12 meters at time t = 0.4 seconds.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A model rocket is launched with an initial upward velocity of 35 m/s.
The rocket's height h (in meters) after t seconds is h=35t-5t
We have to find the time(s) when the rocket's height is 12 meters, we need to solve the equation:
h = 35t - 5t = 30t
We want to find all values of t that make h = 12. So we set h = 12 and solve for t:
12 = 30t
Divide both sides by 30
t = 12/30
t = 0.4
Therefore, the rocket's height is 12 meters at time t = 0.4 seconds.

Answers
The dimension is d and d<n. Thus maximum number of linearly independent vectors that can draw from the set V1, V2....Vn is d.
First note that for "any vector space V, basis B of V is maximal linearly independent set in V". That is there is no other any linearly independent set which contains more than |B| number of elements on B. Let us consider this statement as 1. Two or greater vectors are stated to be linearly independent if none of them may be written as a linear mixture of the others. On the contrary, if at the least certainly considered one among them may be written as a linear mixture of the others, then they may be stated to be linearly dependent. Now here dimension is d and d<n. Thus maximum number of linearly independent vectors that can draw from the set V1, V2....Vn is d.
Thus, the maximum number = d

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 3 large boxes and 2 small boxes has a total weight of 83 kilograms. A delivery of 5 large boxes and 6 small boxes has a total weight of 175 kilograms. How much does each type of box weigh?
large box:
small box:
Answers
Answer:
Large box: 18.5 kg
Small box: 13.75 kg
Step-by-step explanation:
Let L represent a large box, and S represents a small box
We have the equation
3L + 2S = 83 kg
5L + 6S = 175 kg
We time the first equation by -3
-9L - 6S = - 249 kg
5L + 6S = 175 kg
Now Let's find the large box weighs first
Add both equation and we get
-4L = -74 kg
L = 18.5 kg
Now put 18.5 in for the L to find the weight of the small box
5(18.5) + 6S = 175 kg
92.5 + 6S = 175 kg
6S = 82.5 kg
S = 13.75 kg
Answer:
x as large; y as small
3 large + 2 small = 83 (1st equation)
5 large + 6 small = 175 (2nd equation)
3x + 2y = 83 (multiply by -5)
5x + 6y = 175 (multiply by 3)
-15x - 10y = -415
15x + 18y = 525 (simplify)
8y = 110
y = 13.75 (small box weight)
3x + 2y = 83 (substitute the value of y)
3x + 2(13.75) = 83
3x + 27.5 = 83
3x = 55.5
x = 18.5 (large box weight)
CHECKING:
3x + 2y = 83
3(18.5) + 2(13.75) = 83
55.5 + 27.5 = 83
83 = 83 (1st equation is proven right)
5x + 6y = 175
5(18.5) + 6(13.75) = 175
92.5 + 82.5 = 175
175 = 175 (2nd equation is proven right)
therefore, large box weight is 18.5kg and the small box weight is 13.75kg.

The rate of change of the given data between 3 and 7 hours is; 19 miles per hour
How to calculate the rate of change?We are told that rate of change is the difference between what the value of the data began at versus the value the data ended at.
Now, the formula for the rate of change between two coordinates (x₁, y₁) and (x₂, y₂) is;
Rate of change = (y₂ - y₁)/(x₂ - x₁)
Now, we are told that we should find the rate of change from 3 to 7 hours and so we first write the coordinates;
(3, 209) and (7, 285)
Thus;
Rate of change = (285 - 209)/(7 - 3)

0.003 is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations
To calculate the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations.The mean is the expected number of calls involving a fax transmission, while the standard deviation is the measure of variability in the distribution. We then use this information to calculate the probability of exceeding the expected number by more than 2 standard deviations, which can be done using the z-score formula. The z-score for values more than 2 standard deviations away from the mean is 2.33, which corresponds to a probability of 0.003. Thus, the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations is 0.003.

Equation of line passing through the point (1, 2) and perpendicular to the line y = 3x - 1 is A. x+3y+7=0 B. x+3y-7=0 B.x+3y=0 D. x-3y=0
Answers
To find the equation of the line that passes through the point (1, 2) and is perpendicular to the line y=3x-1, we can first find the slope of the line y=3x-1. The slope of this line is 3, so a line perpendicular to it will have a slope of -1/3. We can then use the point-slope form of the line to write the equation of the line that passes through (1,2) and has a slope of -1/3. The point-slap form of a line is given by y-y₁ = m(x-x₁), where (x₁,y₁) is a point on the line and m is the slope of the line. Plugging in the coordinates of the point (1,2) and the slope -1/3, we get the equation y-2 = -1/3(x-1), which simplifies to y-2 = -x/3 + 1/3. Multiplying both sides of the equation by 3 to get rid of the fractions, we get 3y-6 = -x+1. Finally, we can move all the terms to one side of the equation to get the standard form of the line: 3y-x-5 = 0. Therefore, the equation of the line that passes through the point (1, 2) and is perpendicular to the line y = 3x - 1 is x-3y-5=0, so the correct answer is A.

Harry needs wood pieces to complete a project in woodshop class. He needs three pieces of wood that have a length of two and three fourths feet and six pieces of wood that are one and one third feet. What is the total amount of wood that Harry will need for the project?
four and one twelfth feet
sixteen and one fourth feet
three and four sevenths feet
six and one third feet
Answers
Answer:
D) six and one third feet
Step-by-step explanation:
To find the total amount of wood that Harry needs, we need to find the total length of the three pieces of wood that are two and three fourths feet long and the total length of the six pieces of wood that are one and one third feet long.
The three pieces of wood that are two and three fourths feet long have a total length of 3 * 2 and 3/4 = 6 and 1/4 feet.
The six pieces of wood that are one and one third feet long have a total length of 6 * 1 and 1/3 = 8 and 2/3 feet.
To find the total length of all the pieces of wood, we need to add the total length of the three pieces that are two and three fourths feet long and the total length of the six pieces that are one and one third feet long. This gives us a total of 6 and 1/4 + 8 and 2/3 = 14 and 7/12 feet.
Therefore, Harry will need a total of 14 and 7/12 feet of wood for the project. This is equivalent to approximately six and one third feet, so the correct answer is d) six and one third feet.
