Answer:
y=7
Step-by-step explanation:
Answer:
Perimeter of base = 18 ft
Height = 7 ft
Base area = 12ft²
SA= 150 ft² *
Step-by-step explanation:
Perimeter of base = 8+5+5=18 ft
Height = 7 ft
Base area = 1/2x8x3=12ft²
SA= (8x7)+(12+12)+2(5x7)=56+24+70=150 ft²
*There are several different way to figure out the surface area, so I’m not sure exactly how they want it displayed. 150 is the answer though. Plus, I think there was supposed to be an addition sign between the first two parentheses.
Answer:
74%
Step-by-step explanation:
Let the weight of price = y%
The weight of quality = 2y%
The weight of delivery reliability = 2y%
Since the sum total of the weights is 100, it implies that:
y% + 2y% + 2y% = 100%
5y% = 100%
y = 100/5
y = 20
So the respective weights are as below:
Price = 20%
Quality = 40%
Delivery reliability = 40%
Weight score = score x category weight
For the supplier:
Price score = 40
Quality score = 90
Delivery reliability score= 75
Overall weighted score = (Price score x Price weight) + (Quality score x Quality weight) + (Delivery reliability score x delivery reliability weight)----- (1)
Substituting into (1), we have :
Overall weighted score = (40 x 20%) + (90 x 40%) + (75 x 40%)
= 8 +36 +30
= 74%
Answer:
x ≈ 95.6
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between trig functions and sides of a right triangle. Here, the hypotenuse of the triangle and the side adjacent to the given angle are marked, so the relationship of choice is ...
Cos = Adjacent/Hypotenuse
__
Using the values shown, we have ...
cos(15°) = x/99
Solving for x gives ...
x = 99·cos(15°) ≈ 95.6
The length of the side marked x is about 95.6 units.
