The length and width of a rectangle are measured as 27 cm and 50 cm, respectively, with an error in measurement of at most 0.1 c
Tomtit [17]

Answer:

7.7cm

Step-by-step explanation:

Area of a rectangle is expressed as

A = Length × Width

A = LW

Let dL and dW be the errors in the measurements.

If there is an error of at most 0.1cm each in the measurement, then dL = dW = 0.1cm.

The area of the rectangle with error will be expressed as A = LdW + WdL

Given L = 27cm and W = 50cm

A = 27(0.1)+50(0.1)

A = 2.7+5.0

A = 7.7cm

Hence, the maximum error in the calculated area of the rectangle is 7.7cm

NEED ANSWER ASAP!!! Express your answer in scientific notation. 9.3 X 107 - 3.14 X 106
kirza4 [7]

Answer:

89.86\times 10^6

Step-by-step explanation:

9.3\times 10^7 - 3.14\times 10^6\\

In order to simplify the above expressions we make sure that we get same powers of 10 for both the terms.

So, we multiply and divide the first term with 10

Dividing first term by 10.

\frac{9.3\times 10^7}{10}\\9.3\times 10^{7-1}\\9.3\times 10^6\\

Now multiplying it by 10.

10\times9.3\times 10^6\\93\times 10^6

Evaluating the new expressions.

93\times 10^6 - 3.14\times 10^6\\

Taking 10^6 common factor out.

(93-3.14)\ties 10^6

=89.86\times 10^6

How do you solve the inequality 12 < x + 5 so that the variable "x" is on the left side?
Eduardwww [97]
The like terms are 12 and 5, so you have to subtract 5 from both sides.
12 < x + 5
-5. -5
7 < x
We can just switch it around so x is in the left side.
x > 7
