147.1 is what percent of 155

Harrizon [31]

Solution for what is 147.1% of 155

155/x=100/147.1
(155/x)*x=(100/147.1)*x - we multiply both sides of the equation by x
155=0.67980965329708*x - we divide both sides of the equation by (0.67980965329708) to get x
155/0.67980965329708=x
228.005=x
x=228.005

now we have:
147.1% of 155=228.005

A cement path consists of six equal-sized cement squares arranged in a row to form a rectangle. If the total area of the path is

Bingel [31]

Answer:

24 feet

Step-by-step explanation:

Given that:

The length of the rectangle is 6 times the side of a cement square.

Now, this rectangle is formed from 6 squares;

The total area of the path of this square = 96 square feet;

The area of each square now = 96/6 = 16 square feet

Recall that:

Area of a square = S²

where S is the side length

16 = S²

S = $\sqrt{16}$

S = 4 ft

The length of the path in feet now is: L × w

= 6 × 4

= 24 feet.

A bed is 2400 a discount of 25% was given on the

Brrunno [24]

Answer:

800

Step-by-step explanation:

Given: The selling price of bed is 2400.

Discount offered is 25%

Lets assume the cost of bed be "x"

Discount offered on the cost price of bed= $\frac{25}{100} \times x= 0.25x$

∴ Discount offered on the cost price of bed= 0.25x

We know the selling price of bed after discount provided.

Finding the cost price of the bed.

⇒ $x-0.25x= 2400$

⇒ $0.75x= 2400$

cross multiplying both side.

∴ $x= \frac{2400}{0.75} = 3200$

∴ Cost price of the bed is 3200.

We know selling price of the bed is 2400.

Now, finding the saving.

Saving on the price of bed= Cost price- selling price

Saving= $3200-2400= 800$

Hence, saving on the purchase of the bed is 800.

15c² - 5c. Factorise completely

KATRIN_1 [288]

Looking at the problem, what we must do to complete this question is to completely factor the expression that was provided. The expression that was provided is $15c^2 - 5c$ .

The first step that we must do is to take a look at the expression and see what the two pieces of the expression have in common. We can see that both $15c^2$ and $-5c$ have the number 5 and the variable c associated with them so we can factor out those two.
