Rajni bought 2 1/2 kg onion at ₹ 30 1/2 per kg. Find the amount spent by Rajni

tia_tia [17]

Step-by-step explanation:

Given that

The cost of 1 kg onions = Rs. 30 1/2

The cost of 1 kg onions = Rs. 61/2

If Rajini bought 2 1/2 kg onions then

The total cost of 2 1/2 kg onions

→ 2 1/2 ×( 61/2)

→ (5/2)×(61/2)

→ (5×61)/(2×2)

→305/4

Rs. 305/4 or Rs. 76 1/4

The cost of 2 1/2 kg onions is Rs. 76 1/4.

What is the approximate distance from the origin to the point (3, −4, 5)? Round to the nearest unit. 4 units 7 units 8 units 9 u

Dafna11 [192]

Answer:

Option B is correct.

Step-by-step explanation:

The distance formula used is:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2+(z_{2}-z_{1})^2}$

We need to find distance between origin and other point (3,-4,5)

Origin is: (0,0,0)

x₁ = 0, y₁ = 0, z₁ =0 and x₂= 3, y₂= -4 and z₂ = 5

Putting values in the distance formula we get:

$d=\sqrt{(3-0)^2+(-4+0)^2+(5-0)^2}\\d=\sqrt{(3)^2+(-4)^2+(5)^2}\\d=\sqrt{9+16+25}\\d=\sqrt{50}\\d=7$

The Distance from the origin to the point (3, −4, 5) is 7 units.

Option B is correct.
