Adam, Beth, and Carly walked a total of 10 miles collectively. Beth walked twice as far as Adam, and she walked a half a mile further than Carly. If a = number of miles Adam walks, b = number of miles Beth walks, and c = number of miles Carly walks, which equation is NOT true for this situation?A) b = 2a
B) b = c + 0.5
C) 3a + c = 10
D) a + 2c = 10.5

Answers

D) a+2c=10.5

Since b=c+(1)/(2)
a+b+c=10
a+(c+1/2)+c=10
a+2c+1/2=10
a+2c=9.5

Answer: Option 'D' is not correct.

Step-by-step explanation:

Since we have given that

Total distance walked by Adam , Beth, and Carly = 10 miles

Let number of miles Adam walks be a

Let number of miles Beth walks be b

Let number of miles Carly walks be c

According to question,

Beth walked twice as far as Adam

So, the equation will be

b=2a

Thus, Option 'A' is satisfied.

Now, Beth walked a half a mile further than Carly.

So, the equation will be

b=c+0.5

Thus, Option 'B' is correct.

Now, we substitute the first equation, then we get

a+b+c=10\na+2a+c=10\n3a+c=10

Thus, Option 'C' is correct.

The only incorrect equation is Option 'D' .

If your annual salary is $68,900, how much would be your salary in 3 years?. Write anEquation and solve the problem

Answers

Answer:

206,700

Step-by-step explanation:

We know that the starting salary is $68,900. And we need to figure out the salary during a 3 years period. so we take the one year salary (68,900) and multiply that by 3, for the 3 years. (3 × 68,900) which equally 206,700 dollars.

The areas of two circles are 36(pi) and 64(pi). What is hte ratio of the diameters? of the circumferences?

Answers

A_1=36\pi\ \ \ \Rightarrow\ \ \ \pi r ^2=36\pi\ \ \ \Rightarrow\ \ \ r^2=36\ \ \Rightarrow\ \ r=6\n \nA_2=64\pi\ \ \ \Rightarrow\ \ \ \pi R ^2=64\pi\ \ \Rightarrow\ \ R^2=64\ \ \ \Rightarrow\ \ R=8 \n\n\n (2r)/(2R) = (r)/(R) =(6)/(8)= (3)/(4)\ \ \ \ \ \ \ \ and\ \ \ \ \ \ \ \ (2\pi r)/(2\pi R) =(r)/(R) = (3)/(4)
2,304 because if you multiply 36 x 64 is 2,304 if not multiply 2,304 x 36 x 64 and then divide the answer by 36 & 64 the it should be 2,304
