Answer:
it isn't 205 but my guess is its 115
Step-by-step explanation:
Jose bought 750 bags for $375.00
Each bag cost $375/750= $0.50
He intends to sells them for $0.15 more
He should charge : $0.5 +$0.15=$0.65
1. -35x+710 = -25x+570
-10x=-140
x=14
In 14 weeks, Pedro and Maria's accounts will have the same amount.
2. 9x+90 = 13x+50
-4x=-40
x=10
For 10 square yards of carpeting will the cost be the same for both stores.
3. 0.06x+44 = 0.09x+35
-0.09x= -9
x=100
For 100 miles both companies will charge the same price.
4. 15x+250 = 20x+200
-5x= -50
x= 10
It will take 10 weeks for the amount in each savings account to be the same.
5. 25x+250 = 50x
-25x = -250
x = 10
10 stereos must be sold to make the same amount of money under both plans.
Hope this helps!
We use the law of Cosines to be able to find : 1. The measure of the
third side, when the measure of two sides and the included angle of a
triangle ABC are known. 2. The measure of any angle, when the measure of
the three sides of a triangle ABC are known.
The Law of Cosines is c² = a² + b² - 2abcosΘ. It has four variables;
a, b, c and Θ. Whenever you have a triangle with three of these
variables known, use the Law of Cosines to calculate the unknown
variable.
Answer:
396
Step-by-step explanation:
15x6= 90,Therefore you found one side, now you need to multiply by 4 because their is 4 sides.
90x4= 360
6x6=36
Add them all together, 360+36= 396.
