Answer:
A. cos 159 < 0
Step-by-step explanation:
just did it!
Out of the given statement first statement i.e. cos 159⁰ < 0 is correct.
What is Quadrants?Quadrant is the region enclosed by the intersection of the X-axis and the Y-axis. On the cartesian plane when the two axes, X-axis and Y-axis, intersect with each other at 90º there are four regions formed around it, and those regions are called Quadrants.
Here, angle 159⁰ lies between 90⁰ and 180⁰.
Region between 90⁰ and 180⁰ is 2nd Quadrant.
In second quadrant Sin and cosec are positive, rest all other trigonometric ratios are negative in 2nd quadrant.
Thus, cos will be negative in second quadrant. cos 159⁰ < 0.

At a carnival, $8 buys 15 ride tickets. Brian is going to spend $96 on tickets. How many ride tickets will he be able to buy
Answer:
180 ride tickets
Step-by-step explanation:
Create a proportion where x is the number of tickets he can buy with his $96:
[tex]\frac{8}{15}[/tex] = [tex]\frac{96}{x}[/tex]
Cross multiply and solve for x:
8x = 1440
x = 180
So, he can buy 180 ride tickets
Answer:
180 tickets
Step-by-step explanation:
8x = 15
96x = ?
96/8 = 12
12 x 15 = 180

if there are 40% girls in a class .if there are 35 girls in a class ,find the number of boys
Answer: Girls: 20
Boys: 30
Step-by-step explanation: 40% of 50 is 20, which means there are 20 girls.
Subtract 50-20 to get the number of boys, which is 30.
Answer:
If you asked the correct question, the answer would be 52.5 boys.
But, I believe the correct question is "In a class of 35 students, 40% are girls. Determine the number of boys." And the answer is 21 boys.

The center of an ellipse is (-4,0) one vertex is (-8,0) and one co-vertex is (-4,1). Write the equation of the ellipse
Answer:
The equation of the ellipse is;
[tex]\dfrac{(x + 4)^2}{4^2} + \dfrac{(y - 0)^2}{1^2} = 1[/tex]
Step-by-step explanation:
The parameters of the ellipse are;
The location of the center of the ellipse = (-4 0)
The coordinates of the vertex of the ellipse = (-8, 0)
The coordinates of the the co-vertex = (-4, 1)
The general form of the equation of an ellipse is presented as follows;
[tex]\dfrac{(x - h)^2}{a^2} + \dfrac{(y - k)^2}{b^2} = 1[/tex]
The center of the above equation of an ellipse = (h, k)
The vertex of the above equation are; (h - a, k) and (h + a, k)
The co vertex of the above equation are; (h, k - b) and (h, k + b)
By comparison, we have;
h = -4, k = 0
For the vertex, we have;
When
h - a = -8
∴ -4 - a = -8
-a = -8 + 4 = -4
a = 4
When
h + a = -8
-4 + a = -8
∴ a = -4
a = 4 or -4
We note that a² = 4² = (-4)²
For the covertex, we have;
When
k - b = 1
0 - b = 1
b = -1
When k + b = 1
0 + b = 1
b = 1
∴ b = 1 or -1
b² = 1² = (-1)²
We can therefore write the equation of the ellipse as follows;
[tex]\dfrac{(x - (-4))^2}{4^2} + \dfrac{(y - 0)^2}{1^2} = \dfrac{(x + 4)^2}{4^2} + \dfrac{(y - 0)^2}{1^2} = 1[/tex]
Therefore;
[tex]\dfrac{(x + 4)^2}{4^2} + \dfrac{(y - 0)^2}{1^2} = 1[/tex]

A fraction is the denominator multiplied by the numerator.
1))
A fraction is the numerator multiplied by the denominator.
A fraction is the numerator divided by the denominator.
Answer:
4, A fraction is the numerator divided by the denominator.
Step-by-step explanation:
Fractions do not involve multiplying! It is dividing, so we can rule out all the multiplication related questions.
The top number of a fraction is the numerator 2/3.
The bottom number is the denominator 2/3.
The / is a sign of division.
So, 1 is wrong and 4 is right.

A bucket contains 6 green rubber balls, 4 red rubber balls, and 8 purple rubber balls. Alex removes 3 rubber balls, without replacement, from the bucket. What is the probability that Alex removes a green ball, red ball, and purple ball in that order?
in total there are 6,4,8 which equals 18 .There are 18 balls in total. but Alex removed 3 so now there are 15 balls. There 3 different colors and 15 balls. So there is a 5% out of 15 that you will get a certain color .To find the probability you need to calculate all the possible outcomes.
G=Green R=Red P=Purple
G,R,P
G,P,R
P,G,R
P,R,G
R,P,G,
R,G,P
There is 6 different outcomes, 15 balls and a 5% chance to get a certain color so if you want to exactly get G,R,P there is a (15 divided by 6) chance to get that order.
(I'm not good at calculating that part.)

A student finds the slope of the line between (14, 1) and (18, 17). She writes [tex]\frac{1-17}{18-14}[/tex]. What mistake did she make?
A. She used y-values where she should have used x-values.
B. She should have added the values, not subtracted them.
C. She mixed up the x- and y-values.
D. She did not keep the order of the points the same in the numerator and the denominator.
Answer:
Step-by-step explanation:
She did not keep the order of the points the same in the numerator and the denominator.
I hope this helps!
...............................................................................................................................................
slope is y2-y1/x2-x1
if this was set up correctly it would be 17 - 1/18 - 14
The student simply switched the places of the y change calculation.
