Answer:
First find the distance per hour by dividing
432/24=18
multiply the rate with 16 hours
18 km per hour x 16 hours = 288 km in 16 hours
Step-by-step explanation:
Answer:
288km
Step-by-step explanation:
if a boat travels 432km in 24 hours .
then
it will cover x km in 16 hours
Using Direct Proportion:
[tex] \mathsf{x = \frac{432 \times 16}{24} } [/tex]
[tex] \mathsf{x = \frac{432 \times 2}{3} }[/tex]
[tex] \mathsf{ x = 144 \times 2}[/tex]
[tex] \boxed{ \mathsf{ \implies \: 288km}}[/tex]
hence the boat is gonna travel 288km in 16 hours

A TV station is going to air a movie marathon with 8 movies. It will consist of 2 science fiction movies and 6 horror movies. The horror movies will be aired later in the evening. So, all of the horror movies will be aired last (after both of the science fiction movies). In how many ways can the station air the movie marathon?
Answer:
Total ways to run movies = 1,440
Step-by-step explanation:
Given:
Number of total movies = 8
Number of science fiction movie = 2
Number of horror fiction movie = 6
Find:
Total ways to run movies.
Computation:
Number of science fiction movies way air = 2!
Number of science fiction movies way air = 2×1
Number of science fiction movies way air = 2
Number of horror fiction movies way air = 6!
Number of science fiction movies way air = 6×5×4×3×2×1
Number of science fiction movies way air = 720
Total ways to run movies = 2 × 720
Total ways to run movies = 1,440

Answer:
√33 ≈ 5.7
Step-by-step explanation:
The length of the bottom diagonal is given by pythagoras, let's call it d:
[tex]d =\sqrt{5^2+2^2}[/tex]
Then, the length of the diagonal through the box is also given by pythagoras as:
[tex]\sqrt{d^2 + 2^2}[/tex]
In total, that is:
[tex]\sqrt{5^2 + 2^2 + 2^2} = \sqrt{33} \approx 5.7[/tex]

Theater tickets cost $16 for general admission or $9 with a student ID.
Total ticket sales for a certain showing was $4983. Write an equation
in standard form that shows the possible number of general
admission tickets, x, and student tickets, y, that were sold. Then, find
the total number of student tickets sold if 240 were general
admission tickets.
Answer:
127 student tickets
Step-by-step explanation:
16x + 9y = 4983
x = 240, so substitute that in.
16(240) + 9y = 4983
3840 + 9y = 4983, substract 3840 from both sides
9y = 1143, then divide both sides by 9
y = 127 student tickets
Answer: 16x + 9y = 4983
240 general admission tickets and 127 student tickets
Step-by-step explanation: If you already know that there are 240 general admission tickets and general admission tickets cost 16 dollars the multiply 16 times 240 to get 3840
then subtract 4983 - 3840 to get 1143 which is the money earned on students so now divide 1143 by 9 to get 127

Question 13
Factor the trinomial, if possible. If the trinomial cannot be factored using integers, write prime.
t2 – 2t + 4
a) (t – 4)(t – 4)
b) (t + 4)( t + 2)
c) prime
d) (t + 4)(t – 2)
Answer:
Step-by-step explanation:
Try completing the square: t^2 - 2t + 1 - 1 + 4 becomes (t - 1)^2 + 3. If we set this equal to zero we get (t - 1)^2 = -3. Normally we'd take the square root of both sides, but because that -3 is negative, this is not possible, and the square root of positive 3 is not integer. Thus, the correct response here is "prime."

I WILL GIVE BRAINLIEST PLEASE HELP!! Determine whether the given sequence could be geometric, arithmetic, or neither. If possible, identify either the common ratio or the common difference.
−1280, −320, −80, −20, −5, ....
Answer:
geometric, 1/4
Step-by-step explanation:
An arithmetic sequence will have a common difference. A geometric sequence will have a common ratio. If neither of those describes the sequence, it is "neither."
Obviously the difference between numbers in this sequence is decreasing, so this is not an arithmetic sequence.
__
The ratios of adjacent terms are ...
-320/-1280 = -80/-320 = -20/-80 = -5/-20 = 1/4
The sequence is a geometric sequence with a common ratio of 1/4.

A polynomial function had -5+ root 3i as a root which of the following must also be a root of the function
Answer:
none of the above (talk to your teacher about this)
Step-by-step explanation:
If a polynomial has real coefficients, complex roots come in conjugate pairs.
A root of [tex]-5+\sqrt{3} i[/tex] will have a conjugate of [tex]-5-\sqrt{3}i[/tex], which will also be a root.
__
Here, it looks like the given root is [tex]-5+\sqrt{3i}[/tex], which is different from [tex]-5+\sqrt{3}i[/tex]. None of the listed choices is the complex conjugate of this value.
The value of [tex]-5+\sqrt{3i}[/tex] is ...
[tex]-5+\sqrt{3i}=-5+(\sqrt{\dfrac{3}{2}}+\sqrt{\dfrac{3}{2}}i)[/tex]
so its conjugate is ...
[tex](-5+\sqrt{3i})^*=-5+\sqrt{\dfrac{3}{2}}-\sqrt{\dfrac{3}{2}}i=\boxed{-5+\sqrt{-3i}}[/tex]
You will note that this is not among the answer choices.

Additional comment
When a problem like this has an error in its presentation, we highly recommend you discuss it with your teacher (to get it corrected or deleted for future students). If you feel you must select one of the (erroneous) answer choices, your computer will probably accept the choice of [tex]-5-\sqrt{3i}[/tex], the first one.

A yearbook staff has 30 members. In how many different ways can an editor, photographer, designer, and advisor be selected?
Answer: 657,720
Step-by-step explanation:
If each person can have only one role, we have that:
For the Editor selection we have 30 possible options
for the pothograper we have 29 options, because we already selected one
for the designer we have 28 options
for the advisor we have 27 options
the total number of combinations is the product of the options for each selection;
C = 30*29*28*27 = 657,720
Which of the following is an example of a matched pairs design? A. A teacher calculates the average scores of students on a pair of tests and wishes to see if this average is larger than 80%. B. A teacher compares the pre-test and post-test scores of students. C. A teacher compares the scores of students using a computer based method of instruction with scores of other students using a traditional method of instruction. D. A teacher compares the scores of students in her class on a standardized test with the national average score.
Answer:
B. A teacher compares the pre-test and post-test scores of students
Step-by-step explanation:
the answer is true, because it is a good example to compare the tests between students, we know that a matching pair design is a random model and is used when the experiment allows grouping subjects in pairs based on a variable and each pair will receive randomly a different handling, the answer A is not true because in the example all students are uniformly averaged and the variable is not correlated with subgroups, option c is incorrect because the variable was not randomized and generates classification bias and the option d is incorrect because the teacher compares a small sample as her class with a score of a total sample, but does not intervene on her students when selecting the corresponding group
Matched pair design describes an experimental technique whereby subjects having certain variable or characteristic are paired or matched based on that variable, usually called the key variable. Hence, an example of a matched pair design is "a teacher compares the pre-test and post-test scores of students."
In these type of experimental design, the key or common variable pertinent to both matched subjects is of utmost importance. The only option where, the variable shared is common is the pretest and posttest scores. In the other options, comparing traditional and computer based instructions doesn't match ; similarly, standardized score and national average do not match perfectly.Hence, the most appropriate option is A.

Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected over the x-axis. The reflected figure is labeled figure C. Which best explains why figure A is congruent to figure C? On a coordinate plane, triangle A has points (1, negative 2), (3, negative 2), (3, negative 5). Triangle B has points (4, 0), (6, 0), (6, negative 3). Triangle C has points (4, 0), (6, 0), (6, 3). A Is congruent to B and B Is congruent to C A Is congruent to A, B Is congruent to B, C Is congruent to C Each triangle is a right triangle. Each triangle is an isosceles triangle.
Answer:
A Is congruent to B and B Is congruent to C
Step-by-step explanation:
Let's look at the answer choices:
A: "A Is congruent to B and B Is congruent to C"
Well, clearly, if A ≅ B and B ≅ C, then by the transitive property, we can say that A ≅ C. So, A is very likely correct.
B: "A Is congruent to A, B Is congruent to B, C Is congruent to C"
Just because A is congruent to itself (and same with B and C) doesn't necessarily mean that they're congruent to each other. So, B is wrong.
C: "Each triangle is a right triangle."
Again, there are so many right triangles out there with different dimensions. For example, there are some with sides 3, 4, and 5, and others with sides 5, 12, and 13. They are not congruent, however. So, rule out C.
D: "Each triangle is an isosceles triangle."
This is just like choice C since there are so many variations of isosceles triangles. So D is wrong.
The answer is thus A.
Answer:
First one:
A Is congruent to B and B Is congruent to C
Step-by-step explanation:
Since B is obtained by translating A, it has the same measure angles and sides as A, hence B is congruent to A
C is obtained by reflecting B, which doesn't alter the measure of sides and angles, so C is congruent to B
Therefore by transition, C is congruent to A
In the figure below, which term best describes point V?
Answer:
A
Step-by-step explanation:
The name of the point represented by V is an orthocenter. Option A
An orthocenter of a triangle.A triangle's point of concurrency is its orthocenter. It is the location where the triangle's three altitudes come together.
A line segment drawn perpendicular from a triangle's vertex to the other side or its extension represents the triangle's altitude.
Usually, the letter "H" is used to indicate the orthocenter. It is a crucial point in triangle geometry and has a variety of characteristics and connections to other triangle points like the circumcenter and centroid.
