The expression fails to compute the area of a triangle having base b and height h is (1.0 /2.0)*b*h.
Therefore the answer is A.
The correct expression to compute the area of a triangle having base b and height h is (1/2) * b * h, or equivalently, 0.5 * b * h.
Expression A is incorrect because it uses floating-point division, which may result in round-off errors or inaccuracies in the computation.
Expression B is the correct expression because it uses integer division and the division by 2 is clear.
Expression C is also correct because it uses floating-point division and the division by 2.0 is clear.
Therefore, both expressions B and C are correct, and expression D is a correct equivalent form of B and C.

A puck moves 2.35 m/s in a -22.0° direction. A hockey stick pushes it for 0.215 s, changing its velocity to 6.42 m/s in a 50.0° direction. What is the displacement x
The displacement x of the moving puck is; 0.43 meters
How to find the displacement?The displacement is defined as the change in position of an object. It is also called a vector quantity and has a direction and magnitude
The parameters given here are;
The polar coordinate initial velocity vector; U = 2.35 m/s, -22°
Final velocity vector; V = 6.42 m/s, +50°
This suggests to us that Cartesian x axis is parallel to angle 0° and y axis is parallel to +90°.
Change of velocity component parallel to +90° = magnitude*sinθ,.
Thus, the change of that velocity
Δv = |V|sin(50) - |U|sin(-22)
Δv = 6.42sin(50) - 2.35sin(-22)
Δv = 4.9 - (-0.88)
Δv = +5.8 m/s
The equation for displacement is;
s = ut +1/2at^2
where acceleration time t = Δt = 0.215 s
initial velocity u = |U|sin(-22) = -0.88 m/s
acceleration parallel to u is a = Δv/Δt = +5.8/Δt
a = 5.8/t m/s^2
Thus;
s = -0.88t + ¹/₂* 5.8/t * t²
s = -0.88t +2.9t
s = 2.0t
s = 2.0 * 0.215
s = 0.43 m

Step-by-step explanation:
a row n adds the number n to the sum (= the first number from the right in row n-1), and therefore also n to the 3rd number from the right of row n-1.
in any case, the first number from the right is the result of
1 + 2 + 3 + 4 + 5 + ... + n-1 + n
that sum is
n(n+1)/2
for the row 20 that is
20×21/2 = 10×21 = 210
the 3rd number from the right in row 20 is then

∠A and ∠B are vertical angles. If m∠A = (7x+4) and m∠B = (8x - 20) then find the measure of ∠B
Since ∠A and ∠B are vertical angles, they have equal measures, so m∠A = m∠B. We can set the two expressions equal to each other:
7x + 4 = 8x - 20
Solving for x:
-x = -24
x = 24
So, m∠A = 7x + 4 = 7 * 24 + 4 = 188, and m∠B = 8x - 20 = 8 * 24 - 20 = 188.
Therefore, the measure of ∠B is 188 degrees.

Step-by-step explanation:
First off, what is a "mode"?
The mode in a set of data is simply the most common answer/outcome;
Next, we need to understand the data;
In this case, families were asked about the number of cats they have;
The children answered 0, 1, 2 or 3;
8 families have 0 cats,
6 have 1,
10 have 2,
x have 3
So, the mode will be the most common answer to how many cats a family has;
As we can see from the data, the most common response was 2, i.e. 10 families have 2 cats, compared to only 8 with 0 cats and 6 with 1 cat;
If we know the mode is 2, the value of x has to be less than 10 as it is not the most common response;
The largest possible value will be 9.
If the mode is 3, then that means the x has to be the greatest number of responses;
Since the greatest number of responses to the other options is 10, then the number of responses to having 3 cats has to be at least 11;
The smallest possible value of x, if the mode is 3, will be 11.

solve the following systems of linear equations by graphing
y=2/3x+4 and y=/x-1
Answer:
The solution to the system is (1.8, 7.6)
Step-by-step explanation:
To solve the system of linear equations by graphing, we need to plot the two lines on the same coordinate plane and find the point where they intersect, which will be the solution of the system.
Plot the lines:
y = 2/3x + 4 can be written as y = (2/3)x + 4, where the slope is 2/3 and the y-intercept is 4.
y = -x + 1 can be written as y = -x + 1, where the slope is -1 and the y-intercept is 1.
Find the intersection point:
To find the intersection point, we can substitute the x-value from one equation into the other equation. Let's use y = 2/3x + 4.
Substitute x from y = 2/3x + 4 into y = -x + 1:
-x + 1 = 2/3x + 4
Multiplying both sides by -3, we get:
3x - 3 = -2x - 12
Adding 2x to both sides, we get:
5x - 3 = -12
Adding 12 to both sides, we get:
5x = 9
Dividing both sides by 5, we get:
x = 1.8
Now that we have x, we can substitute it back into either equation to find the corresponding y-value. Let's use y = 2/3x + 4:
y = 2/3x + 4
y = 2/3 * 1.8 + 4
y = 3.6 + 4
y = 7.6
So the solution to the system is (1.8, 7.6), which is the point where the two lines intersect.
As part of their opening day celebration, Benny’s Bakery made 150 cupcakes. The cupcakes all looked identical on the outside, but 6 of them had caramel inside. Customers who bought a cupcake with a caramel inside won a free cake. The cupcakes were randomly arranged and customers were allowed to choose their own cupcakes. Zoe was the first customer in line and bought three cupcakes. What is the probability that exactly one of Zoe’s cupcakes had caramel inside?
The probability that exactly one of Zoe's cupcakes had caramel inside after the cupcakes were randomly arranged and customers were allowed to choose their own cupcakes is 1/3266.
The probability that exactly one of Zoe's cupcakes had caramel inside can be calculated as follows:
P(exactly one cupcake with caramel) = (number of ways to choose one cupcake with caramel) / (total number of combinations of three cupcakes)
There are 6 cupcakes with caramel, so there are 6 ways to choose one cupcake with caramel.
Out of 150 cupcakes, there are 150 choose 3 = 19,600 ways to choose three cupcakes.
So, the probability that exactly one of Zoe's cupcakes had caramel inside is:
P(exactly one cupcake with caramel) = 6 / 19,600 = 1/3,266
Therefore, the probability that exactly one of Zoe's cupcakes had caramel inside is 1/3,266.

mabel owes $374 on her credit card and is about to make a repayment of $155.What will be the new balance on her credit card
The new credit card balance on her credit card is $219 if no interest is added on balance.
What Is a Credit Card Balance?The total sum of money owing by a cardholder to their credit card company is known as their credit card balance. Balances fluctuate depending on when and how they are used; they rise when purchases are made and fall when payments are made by cardholders. Any sum that is left over at the end of the billing cycle is added to the bill for the following month and is subject to interest. The balances on a person's credit cards play a significant role in determining their credit score. Future lenders will evaluate them to assess the risk (and price) of extending further credit to their clients.
Given that Mabel owes $374 and make a repayment of $155.

X and Z are endpoints of a segment, and point T is on the segment. If XZ = 3x, XT = x + 3, and TZ = 13, then x = and XZ =
We can then plug this value into the given for XZ, which is 3x, to solve for the length of XZ. This comes out to be 18. Therefore, the value of x is 6, and the length of XZ is 18.
x = 6, XZ = 18
To solve for x, we can use the formula for the midpoint of a segment, which is (x + z)/2.
Plugging in the given values, we get (x + 13)/2 = 6.
Simplifying, we get x = 6.
To solve for XZ, we can simply plug in the given value for x, which is 6.

ayudaa jajaja
The area and volume based on the information will be area 144 √3 square meters and 240√3 cubic meters
How to calculate the areaTo calculate the area of the hexagonal prism, you need to calculate the area of each face and add them up. To calculate the area of one face of the hexagon, you can use the following formula:
Area of a regular hexagon = (3 * √3) / 2 * side^2
Plug in the side length of 4m:
Area of a face = (3 * √3) / 2 * 4^2 = (3 * √3) / 2 * 16 = 24 * √3
So the area of one face is 24 * √3 square meters. There are a total of 6 faces, 3 of which are hexagons, so the total area of the hexagonal prism is:
Total area = 6 * (24 * √3) = 144 * √3 square meters
To calculate the volume of the hexagonal prism, multiply the area of one face by the height:
Volume = (24 * √3) * 10 = 240 * √3 cubic meters
So the volume of the hexagonal prism is 240 * √3 cubic meters
