48. 95,400 mL

50a. 331 yds.

50b. 11,916 in.

Step-by-step explanation:

Some helpful conversions can solve this for you :)

1 liter = 1000 mL

1 yard = 3 feet

1 feet = 12 inches

Now we get started!

48. We have 95.4 Liters, multiply by 1000 because 1000 mL per Liter. Therefore it's 95,400.

a. 3 feet per yard, so 993 feet divided by 3 is 331 yards.

b. 12 inches per foot, so 993 feet multiplied by  12 is 11,916

The price of petrol increased by 8% to Rs 540 per litre. Find the old price.​

Answers

Answer:

The original price is Rs. 50

Step-by-step explanation:

Let the original price be Rs.x

x+8% of x=54

x+(8/100)*x=54

x+8x/100=54

(100x+8x)/100=54

108x/100=54

x=54* 100/108

x=50.

The original price is Rs. 50

Answer:

Rs 500 per liter

Step-by-step explanation:

Let the initial price be x.

We have:

x + 8% of x = 540

Answers

Answer:

45

Step-by-step explanation:

First, we have to find the Nth term of this sequence. Since this is linear we can just find the difference to get the n. For example, we can do 3-2 which is one and we can also do 5-4 which is also 1 which confirms that the n is 1. So in other words, 1n However, we don't write the 1 in front of the n because the n itself represents 1n. Next, we have to take away 1 from the first term, which also gives us 1. This is the adjustment to the 1n. So our answer is n+1, which is the nth term for this linear sequence. So now we just substitute 44 into the equation. 44+1=45, which is the 44th term.

➢ [tex] \sf{t = \dfrac{2 - 3q}{q + 4} }[/tex]

Answer:

t = (2 - 3q)/(q + 4).

Step-by-step explanation:

We cross multiply:

q(t + 3) = 2 - 4t

qt + 3q = 2 - 4t

qt + 4t = 2 - 3q

t(q + 4) = 2 - 3q

t = (2 - 3q)/(q + 4).

Answers

Yes it would be 3,053.63 units^3.

But in our case, from the choices above, it would be (A. 972 pie units^3)

hope this helps.

Step-by-step explanation:

The volume of a sphere with a radius of 9 units is,

⇒ Volume of sphere = 339.12 units³

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Radius of sphere = 9 units

Now, We know that;

Volume of sphere = 4/3 πr²

Radius = 9 units

Hence, We get;

⇒ Volume of sphere = 4/3 πr²

⇒ Volume of sphere = 4/3 × 3.14 × (9)²

⇒ Volume of sphere = 339.12 units³

Thus, The volume of a sphere with a radius of 9 units is,

⇒ Volume of sphere = 339.12 units³
