Answer:

4.86

Step-by-step explanation:

Melanie uses 8.1 pints of blue paint and white paint for her bedroom

2/5 of this amount is blue paint

Therefore the amount of white paint can be calculated as follows

= 2/5

= 0.4×100

= 40%

60/100 × 8.1

= 0.6 × 8.1

= 4.86

Hence 4.86 pints of white paint will be used to paint the bedroom

A customer uses a 50% coupon good toward any household cleaning product. if the customer's purchase consists of the items below,
Vlad [161]
Here is the answer to the given problem above. Given the list of items above, since the 50% coupon only applies to any household cleaning product, this coupon will only apply to the carpet shampoo which has a price of $6.90. So 50% of this would be $3.45. So the rest of the prices of the other items would remain the same. So to sum it all, the total bill would be $8.50, without the sales tax. So we add the sales tax for this and the total would be this: $9.0525. The tax for this of 6.5% tax is 0.5525. Hope this answers your question. Have a great day!

Does anyone know how to solve this?
kondaur [170]

Answer:

Step-by-step explanation:

<2 + <1 + 20 = 180                 A straight line has 180 degrees.

<2 is given as 90 degrees.

90 + <1 + 20 = 180                Combine like terms

<1 + 110 = 180                        Subtract 110 from both sides

<1 = 180 - 110

<1 = 70

<1 + <2 + <3 = 180

<1 = 70

<2 = 90

70 + 90 + <3  = 180

160 + <3 = 180                    Subtract 160 from both sides

<3 = 180 -  160

<3 = 20

20 + 20 + <4 = 180            Straight line theorem stated above.

40 + <4 = 180                     Subtract 40 from both sides

<4 = 180 - 40

<4 = 140

the interest paid for borrowing qn amount of money for 3yrs at the rate of 4%is n108 find the amount of the money borrowed
tankabanditka [31]

Answer:

$864.94

Step-by-step explanation:

So the amount of money over time can be given with an exponential function y=a(b)^x or more specifically y=a(1+r)^x    where r is the growth rate (interest rate)

So the equation can be written as

m= P(1.04)^t    where m represents the amount of money over time, P represents the principle amount, and t represents time in years. Since we're given the amount of interest paid and not the total amount which includes the initial amount borrowed you have to subtract P from the equation. This will give us the equation that we'll use to find the initial amount

I = P(1.04)^t-P  where I represents the interest paid.

plug the values into the equation

108 = P(1.04)^3-P\\108 = P(1.124864) - P\\108 = 0.124864P\\\\864.941 = P
