Answer:
The last one.
Step-by-step explanation:
The formula for surface area are 2(LW+LH+WH). If the numbers were being placed in the formula, it will become 2[(9*7)+(9*12)+(12*7)]. 9*7 is 63, 9*12 is 108, 12*7 is 84 and the sum will be 255, and multiply by 2 is 510.
The answer is 510
Answer:
1. 1,800
2. 500
3. 36,500.03
4. 86.3

Answer:
Step-by-step explanation:
For angle C,
cos(∠C) =
= 0.97
sin(∠C) =
= 0.26
tan(∠C) =
= 0.27
Therefore, from the triangle ABC,
cos(∠A) = cos(90° - ∠C)
= sin(∠C)
= 0.26
sin(∠A) = sin(90 - ∠A)
= cos(∠A)
= 0.97
tan(∠A) =
= 3.73
Angle

A 0.26 0.97 3.73
Answer:
Store A sells the watch $0.50 less than B
Step-by-step explanation:
Store A: 5% of 50 = $2.50 Therefore, store A sells for $47.50
Store B: 20% of 60 = $12.00 Therefore, store B sells for $48.00
