Answer:
x ≈ 73.3
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos39° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{57}{x}[/tex] ( multiply both sides by x )
x × cos39° = 57 ( divide both sides by cos39° )
x = [tex]\frac{57}{cos39}[/tex] ≈ 73.3 ( to the nearest tenth )

Answer:
20 degrees
Step-by-step explanation:
You know that the three angles will add up to 180 degrees, so you can make an equation:
3x (angle 1) + 2x + 20 (angle 2) + 5x - 40 (angle 3) = 180
3x + 2x + 20 + 5x - 40 = 180
Then, solve
combine like terms
10x - 20 = 180
add 20 to both sides
10x = 200
divide both sides by 10
x = 20 degrees
Step-by-step explanation:
3x+5x-40+2x+20=180°{sum of triangles}
10x-20=180
10x=180+20
x=200
10
x=20°
hope it helps.
Ms. MacArthur surveyed students to find the amount of time they spent reading and watching TV last week. The scatter plot below shows the results of her survey and a linear model for her data.James said that, according to the data a student whi watches 6 hours of Tv each week will read for 10 hours ecah week. is james correct why or why not ?
Answers
Answer:
No, because James has confused the hours of watching tv with the hours of reading.
Step-by-step explanation:
This is incorrect. According to the graph, what we have is a point on the line at (6, 10), which implies that a student who reads for 6 hours will watch tv for 10 hours.
It is very likely that James is confusing the hours of watching tv with the hours of reading.

1.) [tex]\bold{\frac{x}{-7.2}=-4}[/tex]:
- Multiply both sides by −7.2:
[tex]-7.2[/tex] × [tex]-7.2=[/tex] Cancels Out[tex]-4[/tex] × [tex]-7.2=28.8[/tex]So your answer is [tex]\bold{x=28.8}[/tex].
2.) [tex]\bold{\frac{3}{2}x=6}[/tex]:- Find the reciprocal and multiply by that on each side:
The reciprocal is [tex]\frac{2}{3},(3*2=6,~2*3=6)[/tex][tex]\frac{3}{2}[/tex] turns into [tex]\frac{2}{3}[/tex][tex]6[/tex] × [tex]\frac{2}{3}=\frac{12}{3}[/tex]- Divide the numerator by the denominator:
[tex]12[/tex] ÷ [tex]3=4[/tex]So your answer is [tex]\bold{x=4}[/tex].
3.) [tex]\bold{\frac{x}{2}=-4}[/tex]:- Multiply both sides by 2:
[tex]\frac{x}{2}[/tex] × [tex]2=x[/tex][tex]-4[/tex] × [tex]2=-8[/tex]So your answer is [tex]\bold{x=-8}[/tex].
4.) [tex]\bold{-5x=26}[/tex]:- Divide both sides by −5:
[tex]-5x[/tex] ÷ [tex]-5=x[/tex][tex]26[/tex] ÷ [tex]-5=-5.2[/tex]So your answer is [tex]\bold{x=-5.2}[/tex].

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting exactly 1 blue?
Answers
Answer: The probability is 0.536
Step-by-step explanation:
We have 3 blue marbles, and 5 red marbles (a total of 3 + 5 = 8 marbles)
First, we take a marble and it is not replaced.
Then we take another marble.
We want to calculate the probability of getting only one blue marble.
Then we have two cases:
1) First we take a blue marble, and after a red marble
2) First we take a red marble, and after a blue marble.
Let's calculate the probability of these two events:
1) The probability of taking a blue marble at random, is equal to the quotient between the number of blue marbles, and the total number of marbles.
this is: p1 = 3/8.
Now we need to take a red marble. Same procedure as before, but now we already taken a marble from the bag, so the total number of marbles is 7 now, and the number of red marbles is 5. The probability here is:
p2 = 5/7
The joint probability (the probability of both events happening) is equal to the product between the individual probabilities, this is:
P = p1*p2 = (3/8)*(5/7) = 0.268
2) Now we first take a red marble, we can calculate the probabilities in the same way than above.
The probability of taking a red marble at first is:
q1 = 5/8
The probability of taking a blue marble in the second draw is:
q2 = 3/7
The joint probability is:
Q = p1*p2 = (5/8)*(3/7) = 0.268
The total probability of getting only one blue marble will be equal to the addition of both the probabilities we found.
Probability = P + Q = 0.268 + 0.268 = 0.536
Choose the two rectangular prisms that have a volume of 36cm^3?
Answers
Answer:
Correct choices: B, D
Step-by-step explanation:
The Volume of a Rectangular Prism
Given a rectangular prism of dimension W, L, and H, the volume is calculated as:
V = WLH
Each small cube of the figure has a volume of 1 cube centimeter. We need to calculate the volume of each solid and determine which ones have a volume of 36 cube cm.
A: V = 5*3*4 = 60 cube cm
B: V = 3*3*4 = 36 cube cm
C: V = 3*4*2 = 24 cube cm
D: V = 6*2*3 = 36 cube cm
E: V = 2*4*2 = 16 cube cm
Correct choices: B, D

For the equation 8x + 2y = 16 What is the slope? What is the y-intercept (write as an ordered pair)? What is the x-intercept (write as an ordered pair)?
Answers
Answer:
Step-by-step explanation:
8x+2y=16
2y=-8x+16
y=-4x+8
slope is -4
y-intercept is (0,8)
x-intercept is (2,0)
Answer:
slope = -4
y-intercept = (0,8)
x-intercept = (2,0)
Step-by-step explanation:
To find the slope:
8x + 2y = 16. First get the y by itself.
2y = -8x + 16. Then divide by 2
y = -4x + 8. So the slope is -4.
y-intercept:
8x+2y=16
8(0)+2y=16
2y=16
y=8
y-int: (0,8)
x-intercept:
8x+2y=16
8x+2(0)=16
8x=16
x=2
x-int: (2,0)

If the sum of a number and seven is doubled, the result is six less than the number. Find the number
Answers
Answer:
-20
Step-by-step explanation:
Let the number be Y
If the sum of a number and seven is doubled, the result is six less than the number, The statement is as expressed below
2(Y+7)= Y-6
Find the value of Y
2Y+14=Y-6
Put the like terms together
2Y-Y=-6-14
Y=-20
The number is therefore -20

2(-20+7)=-20-6
2(-13)=-26
-26=-26

Answer:
(-1, -2) will be the solution.
Step-by-step explanation:
System of equations has been given as,
y = 3x + 1 ---------(1)
Input-output value table for the given line will be,
x -2 -1 0 1
y -5 -2 1 4
y = -x - 3 ----------(2)
Input-output value table for the given line will be,
x -2 -1 0 1
y -1 -2 -3 -4
By plotting the given coordinates we can draw the straight lines.
And the point of intersection (common point) of these lines will be the solution of the given system of equations.
Hence, (-1, -2) will be the solution.
