Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Which equation can be used to calculate the area of the shaded triangle in the figure below?
A) 2(12 + 4) = 32
B) fraction 1 over 2 (12 + 4) = 8
C) 2(12 × 4) = 96
D) fraction 1 over 2 (12 × 4) = 24
Answers
Answer:
D) 1/2 (12x4)=24
Step-by-step explanation:
The answer is D because 12 times 4 gets you the area of the whole rectangle, but then you multiply it by 1/2 to get half of the rectangle's area, which is the shaded part.

#5 = option a (129.38 miles):
We are told that the cities are 17.25 inches apart, and that 2 inches equal 15 miles. First we have to divide 17.25 inches by 2 we end up with 8.62500 inches (not simplified yet). Next, we just take 8.62500 inches and multiply that with 15, which leaves us with 129.37500 inches. Then we just round that to the nearest hundredth which will give us 129.38 inches which means 129.38 miles as well!
#2 = option a (2.4 inches)
We know that bigger rectangle's length is 16 inch and that smaller rectangle's length is 3.2 inches. We just have to calculate the decrease of the length and we do that by dividing. We have to do 16 inches divided by 3.2 inches which equals 5. (You can double check that by multiplying 3.2 inches by 5 which would equal 16 inches) Now to find the width of the smaller rectangle, we just have to divide the width of the bigger rectangle, which is 12 inches, by 5 which would give us 2.4 inches!
#4 = ?
#6 = option c (7.2cm)
So basically I just did 25cm divided by 10cm which equals 2.5cm. (You can also do 25cm divided by 2.5cm to get 10cm if you want to double check). Then I just did 18cm divided by 2.5 cm which led me to the answer 7.2cm)
#3 = ?
Answer: A
Step-by-step explanation: 17.25/2=8.652
8.652*15=129...
rounded it would be equivalent to answer choice A.

Based on the information, it can be inferred that the difference in the circumference of the two circles is 6.31 cm.
How to calculate the circumference of a circle?To calculate the circumference of a circle we must apply the following formula:
2\(\pi\)RR = Radius of the circle.According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:
2\(\pi\)1 = 6.282\(\pi\)2 = 12.59So, to find the difference of the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).
12.59 - 6.28 = 6.31According to the above, the difference of the circumferences would be 6.31 cm.
How to calculate the area of the circle?To calculate the area of the circle we must apply the following formula.
A =\(\pi r^{2}\)
r = radio del círculo.
According to the above, the radiO of both circles would be:
\(\pi 1^{2}\) = 3.14\(\pi 2^{2}\) = 25.13Additionally, to find the difference we must subtract these values:

step two: fuse the vertical line test. Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function

similarities between parallelogram, and trapezoid

A trapezoid has one pair of parallel sides and a parallelogram has two pairs of parallel sides. So a parallelogram is also a trapezoid.
Answer:
Both a parallelogram and a trapezoid have four sides and four angles. Both shapes have opposite sides that are parallel to each other. The main difference between the two shapes is that in a parallelogram, opposite sides are equal in length, while in a trapezoid, only the two parallel sides are equal in length.
