Which pair of angles has congruent values for the sin x° and the cos y°?
35°; 55°
35°; 70°
35°; 145°
35°; 35°
Answer: the correct answer is A. 35, 55
Step-by-step explanation: got it right on my exam today
35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.
What is congruent angle?Congruent angles are the angles that have equal measures.
According to the given question
We have different angles for [tex]sinx[/tex] and [tex]cosy[/tex].
And we have to find "the pairs of angles which has congruent values for sinx and cosy.
Therefore,
35 degree and 55 degree
sin(35) = [tex]sin(\frac{7\pi }{36})[/tex] =0.57
cos(35) = [tex]cos(\frac{11\pi }{36})[/tex] = 0.57
⇒ 35 degrees and 55 degrees are the pair of angles has congruent values for sinx and cosy.
35 degrees and 70 degrees
sin(35) =[tex]sin(\frac{7\pi }{36} ) =0.57[/tex]
cos(70) =[tex]cos(\frac{7\pi }{18} )[/tex] = 0.34
⇒35 degrees and 70 degrees are the pair of angles have not congruent values for sinx and cosy.
35 degrees and 145 degrees.
sin(35)=[tex]sin(\frac{7\pi }{36} )= 0.57[/tex]
cos(145) = [tex]cos(\frac{29\pi }{36} )= -0.8[/tex]
⇒ 35 degrees and 145 degrees are the pair of angles have not congruent values for the sinx and cox.
35 degrees and 55 degrees
sin(35) =[tex]sin(\frac{7\pi }{36} )[/tex]= 0.57
cos(35) = [tex]\frac{x}{y} =\frac{7\pi }{36} = 0.8[/tex]
⇒ 35 degrees and 55 degrees are the pairs of angles have not congruent values for sinx and cosx.
Hence, 35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.

there are 80 people in the audience and 10% have green eyes how many people have green eyes
Answer:
8
Step-by-step explanation:
take the number of people in the audience and multiply by the percent that have green eyes to determine the number with green eyes
80 * 10 %
Change to decimal form
80 *.10
8
Answer:
so, as given 10% have green eyes,
10% of 80
10/100×80
800/100
=8
so 8 people have green eyes

Answer:
x = 6
m∡ABC = 135°
Step-by-step explanation:
∡ABE ≅ ∡CBD therefore we can create the following equation:
3x + 27 = 45
3x = 18
x = 6
∡CBD and ∡ABC are supplementary so 180 - ∡CBD = m∡ABC
180 - 45 = m∡ABC
m∡ABC = 135°

If two-point charges, 2000 meters apart, have charge values of 40 C and -40 C, respectively, what is the value of the mutual force between them? (Coulomb's constant = 9.0 x 109 N•m2/C2).
Answer:
The value of the mutual force between them is 3.6 x 10⁶ N
Step-by-step explanation:
Given;
distance between the two-point charges, r = 2000 m
the value of the two-point charges, q₁ and q₂ = 40 C and -40 C
Coulomb's constant, k = 9 x 10⁹ Nm²/C²
The value of the mutual force between them is calculated by applying Coulomb's law;
[tex]F = \frac{K|q_1|q_2|}{r^2} \\\\F = \frac{(9 \times 10^9)(40\times 40)}{(2000)^2} \\\\F = 3.6 \times 10^6 \ N[/tex]
Therefore, the value of the mutual force between them is 3.6 x 10⁶ N.

Answer:
The mean is 6.
Step-by-step explanation:
To find the mean you need to do the following.
first, add up all the data to get a total.
next, count the amount of data you have.
lastly, divide the total by the count.
Answer:
6
Step-by-step explanation:
our given database is
2,3,6,6,7,8,8,8
first:add up all data:
[tex] \displaystyle \rm2 + 3 + 6 + 6+ 7 + 8 + 8 + 8[/tex]

Marshall is comparing different companies that rent sound systems The total cost, y , for each company includes a used rental fee plus an additional fee based on the number of hours, x , the sound system is rented. Which company had the lowest additional fee per hour for renting a sound system?
Answer:
Company B
Step-by-step explanation:
Given
See attachment for graph
Required
Company with the least additional fee
This means the y-intercept and it represents the flat fee
To get the y-intercept, we simply write out the point where [tex]x= 0[/tex]
From the graph of A, we have:
[tex](x,y) = (0,70)[/tex]
Additional Charges = 70
From the table of B, we have:
[tex](x,y) = (0,50)[/tex]
Additional Charges = 50
From the equation of C, we have:
[tex]y=10x+ 90[/tex]
[tex]y(0) = 10 * 0 + 90[/tex]
[tex]y(0) =0 + 90[/tex]
[tex]y(0) =90[/tex]
Additional Charges = 90
By comparison. company B has the least additional fee because: [tex]50 < 70 < 90[/tex]
Ms Hart had 40 dollars to spend on costume boxes for the musical. If she bought 12 boxes and received 4 dollars in change, how much was each box?
Answer:each box cost =$3
Step-by-step explanation:
Amount of money Ms Hart has to spent on costume boxes=$40
Amount gotten as change after purchase=$4
Amount actually used up buying costume boxes =$40-$4=36
Since she bought 12 boxes , each box cost =$36/ 12=$3

Answer:
30
Step-by-step explanation:
Given that,
No. of pairs of pants = 3
No. of shirts = 5
No. of pairs of shoes = 2
No. of different outfits that Jane can choose from = 3 * 5 * 2
= 30
∵ The maximum number of different outfits would be 30.
HEY BESTIES, HOW DOES AN OUTLIER AFFECT THE DISTRIBUTION OF A DATA SET?
Basically, an outlier is a point on a graph that doesn't really fit the pattern.
An outlier can throw off a mean, if the outlier is larger than the other points, it can make the mean much higher than it should be. Vice versa, if it is smaller, the mean is much lower.

The triangles shown are similar. What is the value of x?
Answer:
x = 10
Step-by-step explanation:
The bigger triangle is 2 times larger than the smaller triangle meaning all of the value of the smaller triangle are 2 times smaller than the bigger triangle and the bigger triangle is 2 times larger than the smaller triangle
Answer:
x = 10
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{x}{5}[/tex] = [tex]\frac{6}{3}[/tex] = 2 ( multiply both sides by 5 )
x = 10

Help I suck at math
Answer:
A
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
We can use this formula to find the equation of the line
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)
(y - 11)/(23-11) = (x-1)/(3-1)
(y-11)/12 = (x-1)/2
y-11 = 6x-6
y = 6x + 5
the rate of change is the slope of the line, while the constant (5) is the y intercept

40. When you translate, (x, y+6) will move
a) 6 units right
c) 6 units up
C
b) 6 units left
O'd) 6 units down
Answer:
A 6 units up
Translation rule
Y rule
+= up
-= down
X rule
+= right
-=left
Reflection rule
Reflection over x axis
Y that was once a positive number, is flipped to a negative
example
6,2 reflected over the x axis.
2=-2
Y axis rule example
-2,7 reflected over the y axis
-2=2
Step-by-step explanation:
If it ever says (example,example) like flipped over the x, it will change the y.
Same for a flip over the y, it will change the x

Tom can paint a fence in 6 hours. Huck can paint a fence in 5 hours. If Tom takes a 30 minute break, how long will it take them to paint the fence together?
Answer:
4 1/11 hours
Step-by-step explanation:
Tom can paint 1/6 of the fence in an hour
Huck can paint 1/5 of the fence in an hour
Tom takes a half-hour break; we can create this equation:
1/6x - 1/2 + 1/5x = 1
use a denominator of 30:
5x/30 - 15/30 + 6x/30 = 30/30
11x/30 = 45/30
multiply each side by 30/11 to get:
x = 45/11 or 4 1/11
