1. What is the space inside an object called? What type of objects have volume?
2. Compare the slopes of parallel lines and perpendicular lines.
3. Explain the difference between a secant and a tangent.
Answer:
1. Volume measured in Cubic units (to the third power), Only 3-D objects have volume.
2. Parallel lines have the same slope and will never intersect. The slope of perpendicular lines are the negative reciprocals of each other, they will intersect a 90 degrees
3. Secant is 1/cosX (1 over cosine of x), tangent is sinX/cosX(sine of x over cosine of x)
Step-by-step explanation:
According to the line plot, what is the total amount of time spent studying by the students who studied for an hour each?
Answer:
2.5 hours
Step-by-step explanation:
The total amount of time studying by students who spent 1/2 an hour studying is the product of the number of students who spent 1/2 an hour studying by 1/2 an hour.
Hence, counting the number of dots on the point marked 1/2 gives the count of students who spent 1/2 an hour studying and multiply this number by 1/2.
Total amount of hours spent = 1/2 * 5 = 2.5 hours

Three boys spent the afternoon playing a video game and then compared their best scores. Al says, "My best today is 1800 points more than yours, Bob." Carlo says, "I was having a good day. My 7200 points is 2/3 as much as your two scores combined, Al and Bob." How many points did each boy get in his best game that afternoon?
Answer:
Bob = 4500
Al = 6300
carlo = 7200
Step-by-step explanation:
the following equations can be derived from the question
A = B + 1800 equation 1 or A - B = 1800
C = 7200 = 2/3 (A + B) equation 2
where A = Al's score
B = Bob's score
C = Carlo's score
Make A + B the subject of the formula in equation 2
A + B = 10,800 equation 3
subtract equation 1 from 3
2B = 9000
B = 4500
Substitute for B in equation 1
A = 4500 + 1800 = 6300

Use the Quadratic Formula
Use the Quadratic Formula to find the zeros of the given
expression. Be sure to show your steps!
2x2-7x+3
Plz help no links
Answer:
1/2 and 3
Step-by-step explanation:
The quadratic formula is as given:
( -b±√(b^2-4ac) )/2a
To use it, plug in the a,b and c values.
ax^2+bx+c
In this case a is equal to 2, b is equal to -7, and c is equal to 3
plugging it into our formula gives us:
(-(-7)±√(-7^2-4*2*3) )/2*2
Which is equal to:
7±√(49-24) / 4
= 7±√25 / 4
=7±5 / 4
=2/4, 12/4= 1/2, 3

Find the values of x and y that make these triangles congruent by the HL Theorem.
Answer:
x = 3 ; y=2
Step-by-step explanation:
to simplify the work we can build a system of two equations
2x+3 = 3y+3
x = y+1
we can now substitute the value of x in the first equation
2(y+1)+3 = 3y+3
2y + 2 + 3 = 3y+3
2y + 5 = 3y+3
y = 2
now we can subisitute the value of y in the first equation
x = 2 + 1 = 3
Verify
2(3)+3 = 6+3 = 9
3(2) + 3 = 6 + 3 = 9
3
2+1 = 3
A town has a population of 2000 and grows at 4% every year. What will be the
population after 15 years, to the nearest whole number?
Answer:
[tex] \frac{4}{?100} \times \frac{2000}{?1} = 80 \\ \\ 2000 + 80 = 2080 \\ \\ 2080 \times 15 = 31200 [/tex]

Answer:
x = [tex]3\sqrt{13}[/tex] = 10.8
Step-by-step explanation:
Both problems are done the same way. I will do the first one and you do the second one. OK?
Move the radius x to make a right triangle. The 6 unit segment bisects the chord. So, the legs of the right triangle are 6 and 9
The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle. Now,
[tex]6^{2} + 9^{2} = x^{2}[/tex]
[tex]x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}[/tex]= 10.8
None of the answer choices are to the nearest tenth. So, I am confused about that.
In the second problem, the answer should be 11.2
There are 8 red marbles, 5 blue marbles, 11 green marbles, 1 yellow marble in a jar. Suppose one marble is selected at random. P(red, green or yellow)
Given:
Number of red marbles = 8
Number of blue marbles = 5
Number of green marbles = 11
Number of yellow marbles = 1
One marble is selected at random.
To find:
The P(red, green or yellow).
Solution:
Number of red, green or yellow marbles = 8 + 11 + 1
= 20
Total number of marbles = 8 + 5 + 11 + 1
= 25
The probability of getting a red, green or yellow marble is:
[tex]P(\text{red, green or yellow})=\dfrac{\text{number of red, green or yellow marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(\text{red, green or yellow})=\dfrac{20}{25}[/tex]
[tex]P(\text{red, green or yellow})=\dfrac{4}{5}[/tex]
[tex]P(\text{red, green or yellow})=0.8[/tex]
Therefore, the value of P(red, green or yellow) is 0.8.
