Answer:
1. Is correct
2. Isn't correct, (It would be number 1)
3. I'm unsure, (But I believe its number 1)
Step-by-step explanation:
2. These are angles across from each other.
3. These are Angles of the same side that don't over lap.
I hope this helps you
Area=height.base/2
Area =2. (x+1)/2
Area =x+1
Use the Pythagorean Theorem: a² + b² = c².
a and b are the legs of the right triangle, and c is the hypotenuse.
2) 5² + b² = 6²
25 + b² = 36
b² = 11
b = 3.3 cm
3) 7² + b² = 8²
49 + b² = 64
b² = 15
b = 3.9 cm
4) a² + 5² = 13²
a² + 25 = 169
a² = 144
a = 12 cm
Answer:
$18500 at 6% and $28500 at 8%
Step-by-step explanation:
Let x represent the amount invested at 6%. Then x+10000 is the amount invested at 8%. The total income from the two investments is the sum of the products of the amount invested and the interest rate:
x·6% +(x+10000)·8% = 3390
0.14x + 800 = 3390 . . . . . . . . collect terms
0.14x = 2590 . . . . . . . . . . . . . .subtract 800
2590/0.14 = x = 18500 . . . . . divide by the coefficient of x
Sue has invested $18500 at 6% and $28500 at 8%.
Answer:
x = 27
Step-by-step explanation:
2/3x -2= 16
+2 +2
---------------------
2/3x = 18
multiply by 3 on both sides
2x = 54
divide by two on both sides
x= 27
