X/y=1/4=x/16
1/4=x/16
times 16 both sides
16/4=x
4=x
first blank (top) is 4

1/4=8/x
tmes 4x both sides
x=32
2nd blank is 32

to blank is 4

Andrea multiplied 6.75 x 10^6 and 0.2 x 10^6 and got 6.95 x 10^6. explain Andrea’s mistake and give the correct answer

Dvinal [7]

Answer:

Correct answer = $1.35\times10^{12}$

Step-by-step explanation:

Given:

Andrea multiplied 6.75 x 10^6 and 0.2 x 10^6 and got 6.95 x 10^6.

Question asked:

Explain Andrea’s mistake and give the correct answer.

Solution:

The above question is of exponential question:

Here Andrea simply added 6.75 to 0.2 and got 6.95 and took 10^6 as common and written down wholly 6.95 x 10^6 which is incorrect.

Here we multiply 6.75 to 0.2 and get 1.35 and secondly to multiply 10^6 with 10^6 we have to understand the rule of exponents:-

As we know:

$a^{m} \times a^{n} =a^{m+n}$

$Similarly,\ 10^{6} \times 10^{6}=10^{6+6}=10^{12}$

Hence when we multiplied 6.75 x 10^6 and 0.2 x 10^6 originally we got $1.35\times10^{12}$

Person A is 49 times older than person B. the sum of their ages 1.450

Pepsi [2]

Answer:

Step-by-step explanation:

Is 1.450 correct? 145 would make more sense. I'd even go with 1,450, just for a laugh. I'll assume 1.450 is the correct number here. I'll assume assute the question eventually asks how old are A and B.

A = 49(B)

A+B=1.450

Substitute:

49B+B=1.450

50B = 1.450

B = 0.029

A = 49(B)

A = 49*(0.029)

A = 1.421
