Answer:
the answer for your question would be 1800
Step-by-step explanation:
you multiply 9000 times by .20
Answer:
7/40
Step-by-step explanation:
There are 3 girls+9 boys = 12 students in the 7th grade
P (girl in 7th grade) = girls/ total
= 3/12 = 1/4
There are 7 girls+3 boys = 10 students in the 8th grade
P (girl in 8th grade) = girls/ total
= 7/10
P(7th grade girl, 8th grade girl) = 1/4 * 7/10 = 7/40
Answer:
y = 2.5x - 2.5
Step-by-step explanation:
slope is y2-y1 / x2-x1
so
2.5- (-2.5)/ 2 - 0
5/2
2.5 for your slope
Answer:
x ≈ 15.6

<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle Measure = 60°
Adjacent Leg = 9
Opposite Leg = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [tangent]: tan60° = x/9
- Isolate <em>x</em>: 9tan60° = x
- Rewrite: x = 9tan60°
- Evaluate: x = 15.5885
- Round: x ≈ 15.6
