Answer:
using question mark as reference angle
Base = 13
hypotenuse = 18
usimg trigonometric ratios
cos? = B/h
? = inverse(13/18) = 43.74 = 44°
Step-by-step explanation:
Answer:
Either 126 mi or 47.62 mi depending on the topic ( Most likely 126 i suppose)
Step-by-step explanation:
If the scale factor is for length,
18*7=126
If it is for area,
18*18*7=2268
length=sqrt2268
l=47.62
Answer:
x = 1
Step-by-step explanation:
Step 1: Write equation
-5(2x - 5) - 3x - 5 = 7
Step 2: Solve for <em>x</em>
- Distribute -5: -10x + 25 - 3x - 5 = 7
- Combine like terms: -13x + 20 = 7
- Subtract 20 on both sides: -13x = -13
- Divide both sides by -13: x = 1
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-5(2(1) - 5) - 3(1) - 5 = 7
-5(2 - 5) - 3 - 5 = 7
-5(-3) - 8 = 7
15 - 8 = 7
7 = 7
Answer: D
Step-by-step explanation: Because there is 3 even numbers and 3 odd numbers so the probability of getting an odd number is 50%
Answer:
original price = 7400
Decreased price = 6800
Difference = 7400 - 6800 = 600
Percentage decrease ![= \frac{600}{7400} \times100 = 8.11\%](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B600%7D%7B7400%7D%20%5Ctimes100%20%3D%208.11%5C%25)
