Answer:
38°
Step-by-step explanation:
a²=b²+c²-2bc cos A
5²=3²+7²-2(3)(7) cos A
-33 = -42 cos A
A = (-33/-42)
A = 38°
Answer:
3.3m+1.4
Step-by-step explanation:
Multiply 5 and 0.9m
Multiply 5 and 0.5
5 times 0.9m is 4.5m
5 times 0.5 is 2.5
Multiply -3 and 0.4m
Multiply -3 and 0.7
-3 times 0.4m is -1.2m
-3 times -.7 is -2.1
4.5m+ 2.5 -1.2m-2.1
Which is 3.3m+1.4
Hope this helps!
Answer:
5000
Step-by-step explanation:
Let x be the number of yearbooks to print and sell.
Each costs $7 = -7x
Sells for $35 = 35x
When business breaks even it means the total cost is equal to the total revenue. Hence:
35x - 7x = 14000
<=> 28x = 14000
<=> x = 5000
So at 5000 yearbooks , they seek before their business breaks even
After five weeks they will have the same amount of money.
