Where dose the A go to tho..
Answer:
The value of y is 36, and the value of z is 54.
Step-by-step explanation:
y has to be a number that can sit at 2y and then add itself to itself and become 3y.
40 is too high, and 35 is too low. Level it out, and you get 36.
8. Answer: (C) 101.3
<u>Step-by-step explanation:</u>
Use the Law of Cosines:
c² = a² + b² - 2ab·cos C
28.2² = 16.9² + 19.5² - 2(16.9)(19.5)·cos C
795.24 = 285.61 + 380.25 - 659.1 cos C
795.24 = 665.76 - 659.1 cos C
129.38 = - 659.1 cos C
-0.196 = cos C
cos⁻¹ (-0.196) = cos⁻¹ (cos C)
101.3 = C

10. Answer: (A) 27.9
<u>Step-by-step explanation:</u>
Use the Law of Cosines:
c² = a² + b² - 2ab·cos C
c² = 25² + 18² - 2(25)(18)·cos 79
c² = 625 + 324 - 900 cos 79
c² = 949 - 171.7
c² = 777.3
√c² = √777.3
c = 27.9
Answer:
Multiplication
Step-by-step explanation:
First multiplication 5x8=40 divided by 2 = 20 add back the three so the equation is now 20+3 =<u>23 The final answer</u>
Go by the order PEMDAS
P-Peretnahesis-there is none so skip this step
E-Exponents-There is none so skip this step
M-Multiplication-and division are mixed so whichever one comes first you do and then do the multiplication and division operations in the order they go
D-Division & multiplication are mixed so whichever one comes first you do and then do the multiplication and division operations in the order they go.
A-Addition and subtraction are mixed so whichever one comes first you do and then do the multiplication and division operations in the order they go
S-Subtraction-and addition are mixed so whichever one comes first you do and then do the multiplication and division operations in the order they go
