A worker is cutting a square from a piece of sheet metal. The specifications call for an area that is 16 cm squared with an erro
masha68 [24]

Given:

area of square, A = 16 cm^{2}

error in area, dA = 0.03 cm^{2}

Step-by-Step Explanation:

Let 'a' be the side of the square

area of square, A = a^{2}                 (1)

A = 16 =  a^{2}

Therefore, a = 4 cm

for max tolerable error in length 'da', differentiate eqn (1) w.r.t 'a':

dA = 2a da

0.03 = 2\times 4\times da

da = \frac{0.03}{8}

da = 0.0375 cm

Out of 200 std in a class. 150 like math , 120 like nepali .if the number of std who like nepali only is one third of the std wh
hichkok12 [17]

<u>ANSWER:  </u>

70 students like both nepali and maths.

<u>SOLUTION: </u>

Given,out of 200 students in a class. 150 like math, 120 like nepali.

The number of students who like nepali only is one third of the students who like math .

We need to find how many likes both subjects.

Let, the number of students who like only nepali be x.

Then, x is one-third of students who like maths.

x = \frac{1}{3} \times students who like maths

\begin{array}{l}{x=\frac{1}{3} \times 150} \\\\ {x=\frac{150}{3}} \\\\ {x=50}\end{array}

Now, out of 120 students who like nepali, only 50 students like nepali alone, which means remaining students like both nepali and maths

Students who like both subjects = 120 – 50 = 70.

Hence,70 students like both nepali and maths.

Evaluate each expression using the values m = 7, r = 8, and t = 2.
Lyrx [107]

Answer:

Step-by-step explanation:

For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is not necessary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5).
