a man sold two typewriters it 2970 each. if he gain 10% on one in 10% loss on father what is his gain or loss percent​
kipiarov [429]

original price of first typewriter = x  

2970/x = 110/100  

x = 2970 x 100/110 = 2700  

Price of first typewriter = Rs 2700  

Original price of second typewriter = y  

2970/y = 90/100  

y = 2970 x 100/90  

y = 3300  

Original price of second typewriter = 3300  

profit from first typewriter = 2970 - 2700 = 270  

Loss from second typewriter =  3300 - 2970= 330  

270 less than 330  

so he lost 330 - 270 = Rs 60 in whole transaction

The product of two numbers is negative which statement is true select two answers
Gelneren [198K]

Answer:

The product of two numbers is negative. Which statement is true? Select TWO answers.

A. The quotient of the two numbers is positive.

B. The quotient of the two numbers is negative.

C. No conclusion can be drawn about the quotient.

D. The signs of both numbers are negative.

E. The sign of one number is positive and the sign of the other is negative.

Step-by-step explanation:

The correct two options are B (the quotient of the two number is negative) and E (the sign of one number is positive and the sign of the other is negative).

To validate Option B; quotient is the result we get when we divide two numbers. For instance: \frac{-10}{5}  = -2\\therefore:\\-10 * 5 = -50

To validate Option E; multiplying two number of opposite sign will give us negative sign. For instance: -5 * 2 = -10

Sin4u=2sin 2u cos 2u​
yKpoI14uk [10]

Answer:

If you've learnt sin(A+B) = sinAcosB + cosAsinB,

sin(4u)

= sin(2u+2u)

= sin(2u)cos(2u) + cos(2u)sin(2u)

= 2 sin(2u) cos(2u).

The stem-and-leaf plot shows the test scores for a chemistry class. How many students had a score greater than 90 points? Stem a
stiks02 [169]
<h3>Answer:  7</h3>

=========================================================

Explanation:

The key states  7 \big| 4= 74

It means that a stem of 7 and leaf of 4 combine to the value 74

We're interested in scores greater than 90, so we'll be focusing on the stems of 9 and 10 only

  • Stem 9. Leaves 1,2,3,4,6,7.
  • Stem 10. Leaf 0

Stem9 has 6 leaves while stem10 has 1 leaf. That's 6+1 = 7 leaves total, which means we have 7 scores above 90. If there was a leaf of 0 for stem9, then we'd have to ignore it (since it forms the score 90). But we don't have to worry about that for this case.
