Which of these is coterminal with an angle in standard position that
measures 140°?
-40 degree
-500 degree
-220 degree
-60 degree
Answer:
Since the angle 140° is in the second quadrant, the reference angle formula is Ar=180°−Ac. A r = 180 ° - 140 = 40°

1.construct a table for the sample space of the random experiment.
2.using the sample space find the probability that the total score of the two dice is:
a. greater than or equal to 5
b. greater than 5 but less than 8.
Answer:
See belowStep-by-step explanation:

P(man) = 8/15P(lady) = 7/15(a)
P(both ladies) = 7/15*6/14 = 1/5(b)
P(both men) = 8/15*7/14 = 4/15(c)
P(same sex) = P(both men or both ladies) = 1/5 + 4/15 = 7/15(d)
P(different sexes) = P(man and lady or lady and man) = 8/15*7/14 + 7/15*8/14 = 8/15Another way:
P(different sexes) = 1 - P(both ladies) - P(both men) = 1 - 1/5 - 4/15 = 8/15#6

a)
P(sum ≥5) = 10/16 = 5/8b)
P(5<sum<8) = P(6 or 7) = 5/16Solve 3b = 6v – 3b, for v.
6b-6
b
b-6
0
Answer:
b = v
Step-by-step explanation:
3b = 6v – 3b
Add 3b to each side
3b+3b = 6v – 3b+3b
6b = 6v
Divide by 6
6b/6 = 6v/6
b = v

Answer:
m∠6 = 110°
Step-by-step explanation:
∠6 and ∠8 are known as corresponding angles meaning they are equal to each other. Since m∠8 = 110°, m∠6 also equals 110°.
Answer:
11o degree
Step-by-step explanation:
angle 6 is 110 degree because the relation between angle 6 and angle 8 is that they are corresponding angles and corresponding angles are always equal.

Answer:
TU = 5.7 inches
Step-by-step explanation:
We solve using Tangent Secant Theorem
RS = 8in
ST = 4in
TU = ?
Using the Tangent Secant Theorem
TU² = RS × ST
TU = √RS × ST
Hence,
TU = √8in × 4 in
TU = √32 in²
TU = 5.6568542495 in
Approximately to the nearest tenth = 5.7 in
Therefore, TU = 5.7 inches
What is the value of x?
x = [ ? ]
Answer:
Step-by-step explanation:
The tangent to the angle makes an angle of 90° with the radius.
The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.
By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore
x = 60-30 = 30°.
Find the value of x
Please help!
Answer:
Step-by-step explanation:
We have to use Pythagorean's Theorem twice here, first to find the length of the dotted line, which I will call h, and then again to find x. First we need to find h so we can use it to find x:
[tex](2\sqrt{5})^2=4^2+h^2[/tex] and
[tex]20=16+h^2[/tex] and
[tex]4=h^2[/tex] so
h = 2. Then again:
[tex]x^2=2^2+22^2[/tex] and
[tex]x^2=4+484[/tex] and
[tex]x^2=488[/tex] so
x = 2√122
What is the volume, in cubic meters, of a rectangular prism with a height of 14
meters, a width of 12 meters, and a length of 2 meters?
Answer:
336 m³
Step-by-step explanation:
You just have to multiply the height × width × lenght:
12×14×2=336
a park is 9/10 mile long and 4/5 mile wide. What is the area of the park? ENTER ANSWER AS A FRACTION FOR EXAMPLE: 4/10.
The park formed like a rectangle so :
Area = length × width
Area = ( 9/10 ) × ( 4/5 )
Area = 9 × 4 / 10 × 5
Area = 9 × 2 × 2 / 5 × 5 × 2
Area = 18 / 25
A DVD case contains 4 comedies and 6 action movies. Suppose you select a movie at random on Friday night, don’t replace the movie because you don’t want to watch it again, and then select another movie on Saturday. What is the probability that you select a comedy on Friday and an action movie on Saturday? I HAVE 5 MINS
Step-by-step explanation:
P(C) = 4/10 = 2/5
P(A) = 6/10 = 3/5

A board 60 in. long is cut into two parts so that the longer piece is 5 times the shorter. What are the lengths of the two
pieces?
Answer:
5x = 5(10) = 50 inches
Step-by-step explanation:
Let x = length of shorter piece then
5x = length of the longer piece
.
x + 5x = 60
6x = 60
x = 10 inches (shorter piece)
.
Longer piece:
5x = 5(10) = 50 inches
Aaron has $35 and a coupon for 35% off for one
item. He wants to buy a new pair of shoes for $41.
Will he be able to get the shoes after the
discount?
Answer:
YES
Step-by-step explanation:
Find 35% of $41. You can basically replace the "of" with multiplication, and then remember that "percent" means "per hundred", so divide 35 by 100.
You will get:
(35/100) x 41
Putting it into decimal form:
0.35 x 41
And you get: $14.35
Remember, you're not done yet, because we have just found the amount of money that will be taken off of the original price. So we have to subtract this from $41.
$41.00 - $14.35 = $26.65
Now compare the prices! Aaron has $35, and with the discount, the shoes will only cost $26.65!
$26.65 is less than $35, so he will be able to get the shoes! Yay for Aaron!

write a quadratic function h whose zeros are - 6 and -5 h (x) =
Answer:
h(x)= x^2+11x+30
Step-by-step explanation:
A quadratic function is in the form h(x) = ax^2 + bx + c.
Since the zeros are -6 and -5, take the opposite signs and add them to the variable x separately.
It should look like this: h(x)= (x+6)(x+5)
Since this is the factored form, we have to solve this equation further.
h(x)= (x+6)(x+5)
h(x)= x^2+6x+5x+30
h(x)= x^2+11x+30

A teacher is making a history test composed of the same number of multiple-choice questions as short-answer questions. She estimates it will take students an average of 2 minutes to complete each multiple-choice question and an average of 3.5 minutes to complete each short-answer question.
Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.
Answer:
8 questions each for short answer questions and 8 questions of Multiple Choice Questions type.
A total of 16 questions.
Step-by-step explanation:
The number of multiple-choice questions and the number of short answer type questions are the same.
Let it be equal to [tex]x[/tex]
→Average time it takes to attempt multiple choice question = 2 minutes
→Total time it takes to attempt multiple choice question = [tex]2 * x[/tex] minutes
→Average time it takes to attempt short answer type question = 3.5 minutes
→Total Time it takes to attempt short answer type question = [tex]3.5 * x[/tex] minutes
Total time for the test should be less than 45 minutes.
Now finally, we can make an equation out of the information listed above:
[tex]2x +3.5x <45[/tex]
[tex]\\ 5.5x <45[/tex]
[tex]x < 8.18[/tex]
Hence the value of [tex]x = 8[/tex]
find the volume of figure b triangular base=2 v=30 triangular base=5
Answer:
468.75 = Volume B
Step-by-step explanation:
The volume of two similar figures is related to the scale factor by cube
Volume A
----------------- = scale factor ^3
Volume B
30 2^3
-------------- = ---------
Volume B 5^3
Using cross products
30 * 125 = 8 Volume B
3750 = 8 Volume B
Divide by 8
3750/8 = Volume B
468.75 = Volume B
