Answer: 10.00
Step-by-step explanation:
You had to multiply and divide and see what you get.
Answer:
B.18. 44 miles
Step-by-step explanation:
We are given that
Distance between A and B=8 miles
Angle B=Angle BCQ=40 degree (Alternate interior angles)
Angle ACB=180-Angle ACP-Angle BCQ
Angle ACB=180-40-40=100 degree
In triangle ABC
Angle A+ Angle B +Angle C=180 degree using sum of angles of triangle property
Substitute the values



degree
Angle A=Angle B
When two angles are equal of a triangle then the triangle is isosceles triangle.
Therefore, triangle ABC is an isosceles triangle.

Now, Sine law

Using the sine law



BC=5.22
AC=BC=5.22 miles
Now, total distance covered by the boat=AB+BC+AC
Total distance covered by the boat=8+5.22+5.22=18.44 miles
Hence, option B is correct.
Since both equations define y, they should be equivalent.
3x+7=x-9
2x+7=-9
2x=-16
x=-8
Plug x in
y=(-8)-9
y=-17
Final answer: (-8,-17)
Hi!
First off, I noticed you're using Khan. I just wanted to say I love Khan :D
Okay so let's solve the inequality.
Whatever we do to the inequality, we have to do it to both sides.
4x - 1 + 1 < 11 + 1
4x < 12
Divide by 4 on both sides
4x/4 < 12/4
x < 3
^ the answer
Hope this helps! :)
