Answer:
46. <u>(3) 29</u>
47. <u>(1) y = -4x + 3</u>
48. <u>(3) 3</u>
49. <u>(3) -1/2</u>
50. <u>(4) 25x - 75</u>
Step-by-step explanation:
<u>Question 46</u>
- Let red marbles be 2x + 3 and black marbles be x
- 2x + 3 + x = 42
- 3x = 39
- x = 13
- No. of red = 2(13) + 3 = 29 marbles
- <u>(3) 29</u>
<u></u>
<u>Question 47</u>
- Parallel to a line means the slope is the same
- <u>(1) y = -4x + 3</u>
<u></u>
<u>Question 48</u>
- For the expression to be undefined, the denominator has to be 0
- x - 3 = 0
- x = 3
- <u>(3) 3</u>
<u></u>
<u>Question 49</u>
- Slope = -4 - 1 / 4 + 6
- Slope = -5/10
- Slope = -1/2
- <u>(3) -1/2</u>
<u></u>
<u>Question 50</u>
- Total = 25x
- Left 3 boxes at home = -3x = -3(25) = -75
- <u>(4) 25x - 75</u>
Answer:
C
Step-by-step explanation:
I think this means you want the secant between 0 and 90 degrees.
The Secant(theta) = 1/Cos(theta)
Cos(theta) = 2/3
1/cos(theta) = 1//2/3 = 3/2
Answer: C
So the hypotenuse=10
Adjacent =5
Opposite=?
H^2=a^2+o^2
10^2=5^2+o^2
100=25+o^2
100-25=o^2
75=o^2 square root both sides we get
O=8.660254
Rounding to the nearest tenth
O=8.7
