Answer:
<h3>#1</h3>
- tangent = opposite leg / adjacent leg
- tan ∠F = DE/ EF
- tan ∠F = 24/7
<u>Option D</u>
<h3>#2</h3>
Sine and cosine are same for complementary angles.
- Complementary of 67° is 90° - 67° = 23°.
- sine 67° = cosine 23°
d = dimes
q = quarters
d+q = 38 coins
q=38-d
0.25q + 0.10d=6.95
0.25(38-d)+0.10d=6.95
9.5-0.25d+0.10d=6.95
-015d=-2.55
d=-2.55/-0.15 = 17
q=38-17 =21
21*0.25 =5.25
17*0.10 = 1.70
5.25+1.70 = 6.95
she had 21 quarters and 17 dimes
Approximately the answer is by using the calculator IS
No not all since for example 5.0 is in decimal form but is not a rational number
Answer:
y = -2x + 3
Step-by-step explanation:
5 x -2 + 3 = -7
3 x -2 + 3 = -7
9 x -2 + 3 = 1
-3 x -2 + 3 = 9
You just have to test all of the options, everything, out and pick what fits.
Hope that helps!
