Answer:
15 x 1 + 5 x 3 = 30
Step-by-step explanation:
If you turn the x into a one then it multiplies 15 by one and then it remains at 15, then you multiply 5 and 3 so that's 15 and then 15 + 15 is 30.
Answer:
Weighted mean grade: 81.2
Letter grade: B
Step-by-step explanation:
5 regular tests:
(63+91+88+84+79) / 5 * 60%
= 405 / 5 * 0.6
= 48.6
Final exam:
86 * 10% = 8.6
Project:
90 * 15% = 13.5
Homework:
70 * 15% = 10.5
So her weighted mean grade is
48.6 + 8.6 + 13.5 + 10.5 = 81.2
215 - 44.49 (I added the two deductions mentally) = 170.51
I see the percentages 2%, 1% and 3% add up to 6%
So we want 6% of 215 or .06 x 215 = $12.90
$170.51 - 12.90 = $157.61 net income.
Answer:
L = 171.79 ft
S = 95.43 ft
Step-by-step explanation:
ASA is a good triangle to solve with law of sines.
The third angle is 180 - 68 - 31 = 81°
183 / sin81 = L/sin68 → L = 171.78966...
183 / sin81 = S/sin31 → S = 95.42683...
35 divided by 12 is 2.92
so she would need to bake 3 bathes to have enough for everyone !!
