Answer:
6
Step-by-step explanation:
8.05 divided by 1.25 is 6.44
The large triangle is an isosceles since both angles at the base each equal 42°.
In an isosceles triangle the altitude z is at the same time median , then it bisects the opposite side in the middle . So w = 120/2 = 60
Now let's calculate z:
tan 42° = (opposite side) / (adjacent side) = z/60
tan 42° = 0.9,
0.9 = z/60 and z = 54
Answer: d = 11/2 or 5 1/2
Step-by-step explanation:
2d - 6 = 5
+ 6 + 6
2d = 11
/2 /2
d = 11/2 or 5 1/2
Answer:
The correct answer is square and parallelogram
Explanation:
- If you turn the rhombus around it will turn into a square
I'm pretty sure $39.31 was the original sales cost because if you use proportions to find out what is 7.2% of 42.35 ( what you get you you subtract 45 by 2.65). Your equation would be x/42.35 = 7.2/100. 42.35 is the whole because tax is adding money onto your original cost, making that the part. When you cross multiply you get 100x = 304.92. Then you divide by 100 on both sides to isolate the variable, to get x = 3.04. But you don't stop there. Since 3.04 is only the 7.2%, you have to subtract that by 42. 35 to get a sum of 39. 31 as your total.
