Answer:
b
Step-by-step explanation:
Only B and F are true. The letters are set up so the parts that you choose must have the letters in the same place on each triangle.
So if ABC is a triangle congruent to PQR
Then AB is congruent to PQ because AB are the first 2 letters of ABC and PQ are the first 2 letters of PQR.
AC is congruent to PR (why?)
Answer:
See below in bold.
Step-by-step explanation:
Let the length of the shortest side be x, then the longest side = 2x.
Also x + y = 2x + 1 where y = length of the middle side,
Simplifying:
2x - x - y = -1
x - y = -1 (A)
Also as the perimeter = 7:
x + 2x + y = 7
3x + y = 7 (B)
Adding (A) and (B):
4x + 0 = 6
x = 6/4 = 1.5
Plug x = 1.5 into equation B:
3(1.5) + y = 7
y = 7 - 4.5 = 2.5.
Answer:
So the shortest side = 1.5, middle = 2.5 and longest = 2*1.5 = 3.
Answer: (a)350 + 0.05x ≥ 600 (b) $5000
Explanation:
Fixed Salary = $350
Variable = 5% on sales
Let x the sales amount
Equation: 350 + 0.05x ≥ 600
350 + 0.05x ≥ 600
0.05x ≥ 600 - 350
0.05x ≥ 250
x ≥ $5000
1520 ÷ 10 = 152
1520 ÷ 20 = 76
1520 ÷ 40 = 38
