The measurement of length of the car is 2.25m, when the width is 1.5 meter. Thus, option B is correct.
What is measurement?Measurement is the process of relating numerical values to physical quantities and phenomena. The sciences, engineering, construction, and other technical fields, as well as nearly all daily activities, all depend on measurement. The components, circumstances, restrictions, and theoretical underpinnings of measurement have thus been extensively studied.
Measurements can be made using only the human senses, in which case they are frequently referred to as estimates, or, more frequently, by using instruments.
These instruments can range in complexity from straightforward rules for measuring lengths to extremely complex systems built to detect and measure things that are completely outside the range of the senses, like radio waves from a far-off star or the magnetic moment of a subatomic particle.
Given that length : width is 3 : 2
let length be 3x and width be 2x
width is given 1.5m
2x = 1.5
x = 1.5/2
x = 3/4
Length = 3x
= 3 × 3/4
= 9/4
= 2.25 m
Thus, the measurement of length of the car is 2.25m, when the width is 1.5 meter.

The inequality that represents the numbers of large, and small, boxes that can be loaded in the trailer is 2x + y ≤ 60
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, One large box and two small boxes weigh a total of 100 pounds. One large box and four small boxes weigh a total of 150 pounds.
Let the weights of large and small boxes be x and y respectively.
x + 2y = 100
x = 100-2y...(i)

Can someone help me solve the first math problem please in a quadratic b model
Answer:
i) To find the maximum height of the projectile, we need to find the highest point that it reaches before falling back to the ground. In this case, the maximum height is the vertex of the parabola. To find the vertex, we can use the formula:
x=-b/2a
(12,845)
Substituting this value back into the original height equation, we find the maximum height:
h = -5(12)^2 + 120(12) + 125 = -300 + 1440 + 125 =845
So the maximum height of the projectile is 845 meters.
ii) To find when the projectile reaches its maximum height, we need to find the x-coordinate of the vertex of the parabola. As we found above, the x-coordinate of the vertex is 12 seconds. So the projectile reaches its maximum height at 12 seconds.
Write an exponential function in the form y=ab^x that goes through points (0,13) and (2,637)
Answer:
y=13(7)^x
Step-by-step explanation:
x = 0, y = 13, so we know that a = 13.
13b^2 = 637 ==> x=2 and y=637
b^2 = 49 ==> divide both sides by 13
b = 7 ==> take the square root on both sides
y = 13 * 7^x ==> plug in 7 for b in y = 13b^x

how to multiply fraction with one fraction having the lcm and two other fractions being a factor of it
Multiplying fractions can be a tricky task, but with the right steps, it can be easily accomplished.
To multiply two fractions together, first find the least common multiple (LCM) of the two fractions.
Once you have the LCM, divide it by each of the two fractions and multiply the resulting numbers together. This will give you the final answer to your multiplied fractions.
Let's look at an example. Suppose you wanted to multiply 3/4 and 5/8 together. First, you would need to find the LCM of 3/4 and 5/8. The LCM in this case would be 24.
Now divide 24 by 3/4 and 5/8 to get 32/24 and 30/24 respectively. Multiplying 32/24 and 30/24 together would give you 960/576 as the answer.

Semicircles of diameter 2'' are lined up as shown. What is the area, in square inches, of the shaded region in a 1-foot length of this pattern?
The shaded region is made up of the area of a rectangle minus the areas of the semicircles. The semicircles have a diameter of 2 inches, so the radius of each semicircle is 1 inch.
The area of each semicircle can be found using the formula pir^2, where r is the radius. So the area of each semicircle is pi1^2 = pi square inches.
The area of the rectangle is found by multiplying the length by the width: 1 foot * 12 inches/feet = 12 square inches.
The shaded region is the area of the rectangle minus the area of the semicircles. So the area of the shaded region is 12 square inches - 2* pi square inches = 12 - 2* pi square inches.

A graph is called a regular graph if the degree of each vertex is equal.
N complete vertices make up an (N-1) regular graph.
Proof: Each vertex in a complete network with N vertices is connected to each of the (N-1) remaining vertices. Therefore, each vertex's degree is (N-1). The graph is hence (N-1) Regular.
If the degree of each vertex is equal, a graph is said to be a regular graph. If the degree of each vertex is K, a graph is said to be K regular.
A regular graph in graph theory is one in which every vertex has the same number of neighbors or the same degree of valency. The stronger requirement that each vertex's indegree and outdegree be equal must also be met by a regular directed graph.

Giovanna made an error when calculating the height of a stack of 7 books that are each 2 5/8 inches thick. The correct calculation was 14 7/8 inches, however, she calculated 14 + 5/8 inches. This is incorrect because it is necessary to add the fractions together in order to get the correct answer. To calculate the height of the stack of books, we need to add each book's thickness together. Since each book is 2 5/8 inches thick, we start by adding the whole numbers: 2 + 2 + 2 + 2 + 2 + 2 + 2 = 14. Then, we add the fractions: 5/8 + 5/8 + 5/8 + 5/8 + 5/8 + 5/8 + 5/8 = 7/8.

The probability that the sample contains two white balls and two red ones is 0.264. There are multiple draws without replacement.
How to calculate probability?Probability of an event can be expressed as
P(A) = n(A) / n(S)
Where
P(A) is the probability of an event An(A) is the number of favorable outcomesn(S) is the total number of events in the sample spaceAn urn contains 6 white balls and 15 red balls. A sample of four balls is selected at random from the urn. Find the probability that the sample contains two white balls and two red ones!
It means that there will be multiple draws without replacement.
The total balls are 6 + 15 = 21 balls.
The probability of drawing two white balls and two red ones is
= P(1st is white ∩ 2nd is white ∩ 3rd is red ∩ 4th is red)
= P(1st is white)*P(2nd is white)*P(3rd is red)*P(4th is red)
= (6/21)*(5/20)*(15/19)*(14/18)

multiply through by 8 ( the LCM of 4 and 8 ) to clear the fractions
2x - 3y = 24 → (1)
[tex]\frac{5}{3}[/tex] x - [tex]\frac{y}{2}[/tex] = 12
multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions
10x - 3y = 72 → (2)
multiplying (1) by - 1 and adding to (2) will eliminate y
- 2x + 3y = - 24 → (3)
add (2) and (3) term by term to eliminate y
8x + 0 = 48
8x = 48 ( divide both sides by 8 )
x = 6
substitute x = 6 into either of the 2 equations and solve for y
substituting into (1)
2(6) - 3y = 24
12 - 3y = 24 ( subtract 12 from both sides )
- 3y = 12 ( divide both sides by - 3 )
y = - 4

I took a loan from the bank and I paid an interest of 1,500 at what rate and I pay if the loan was 5000 for 3 years
Answer:
Step-by-step explanation:
To calculate the rate :
Interest = P x R x T
100
Here, P = 5000, T = 3, I = 1500
Therefore,
1500 = 5000 x R x 3
100
1500 = 150 R
1500 = R
15
10 = R
Thus, the rate is 10%

judith surveyed some students at her school about their favorite primary color. yellow 2 red 5 blue 3 what is the experimental probability that the next student judith talks to will pick red? write your answer as a fraction or whole number. p(red)
The experimental probability that the next student Judith talks to will pick red is 1/2.
Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means.
Given that,
Yellow = 2
Red = 5
Blue = 3
Finding the experimental probability
Total number of trials = 2+5+3 = 10
Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes
Probability = red/ Total number of trials = 5/10 = 1/2
Thus, the experimental probability that the next student Judith talks to will pick red is 1/2.

Triangle proportionality theorem and the segment addition postulate, indicates that A_F : AT = A_F : 4×A_F, therefore;
A_F : AT = 1 : 4
What is the triangle proportionality theorem statement?The triangle proportionality theorem states that a segment drawn in a triangle, such that it is parallel to one side of the triangle and intersects the other two sides at two distinct points, then the proportion in which the segment divides the other two sides are the same.
The specified details of the triangle ΔABC are;
The location of the point D = AB, the location of the point B = AC
The point of intersection of the angle bisector of angle ∠A and DE = F
The point of intersection of the angle bisector of angle ∠A and BC = Point T
AD = 1, DB = 3, AE = 2, EC = 4
Drawing a line CU parallel to DE from point C to intersect AB at U, according to the triangle proportionality theorem, we get;
AE : EC = 2 : 4 = AD : DU = A_F : FV
AD : DU = 1 : 2
A_F : FV = 1 : 2
Therefore; FV = 2 × A_F
FV : VT = DU : BU = 2 : 1
FV = 2 × VT
2 × VT = 2 × A_F by substitution property, therefore;
FV = 2 × A_F
AT = A_F + FV + VT (segment addition postulate)
Therefore; AT = A_F + 2 × A_F + A_F = 4×A_F
A_F : AT = A_F : 4 × A_F = 1 : 4
