1 answer:

8 0

When you ask, "What is 4.5 as a decimal?", we assume you want to know what 4.5 percent is as a decimal. In other words, 4.5 percent converted to decimal.

First, we will tell you why it is useful to know 4.5 as a decimal.

Normally, to calculate 4.5 percent, you would multiply a number by 4.5 percent and then you would take the product of that and divide it by 100 to get the answer.

Instead, you can simply multiply a number by 4.5 as a decimal to get the answer.

4.5 percent means 4.5 per hundred. Therefore, to get 4.5 as a decimal, all you have to do is divide 4.5 by 100 like so:

4.5 ÷ 100 = 0.045

The temperature falls from 0 degrees to Negative 12 and one-fourth degrees in 3 and one-half hours. Which expression finds the c

ANEK [815]

Answer:

The expression used to find the change in temperature per hour is Algebraic expression

Thus per hour; the temperature falls at the rate of $- 3\dfrac{1}{2}^0$

Step-by-step explanation:

A temperature falls from 0 to $- 12\dfrac{1}{4}$ in $3\dfrac{1}{2} \ hours$

Which expression finds the change in temperature per hour.

From the above given information;

The initial temperature is 0

The final temperature is $- 12\dfrac{1}{4}$

The change in temperature is $\Delta T = T_2 - T_1$

$\Delta T = -12\dfrac{1}{4} -0$

$\Delta T = -12.25$

Thus;

-12.25 ° = 3.5 hours

To find the change in x° per hour; we have;

x° = 1 hour

The expression used to find the change in temperature per hour is Algebraic expression

From above if we cross multiply ; we have;

(- 12.25° × 1 hour) = (x° × 3.5 hour)

Divide both sides by 3.5 hours; we have:

$\dfrac{-12.25^0*1 }{3.5}=\dfrac{ x^0 *3.5}{3.5}$

x° = - 3.5

x° = $- 3\dfrac{1}{2}$

Thus per hour; the temperature falls at the rate of $- 3\dfrac{1}{2}^0$

The sum of the two digits of a number is 16. The number formed by reversing the digits is 18 more than the original number. Dete

nydimaria [60]

9u-9t=18

original no. is 10t+u
reversed no. is 10u+t

so its (10u+t)-(10t+u)=18
which gives 9u-9t=18

A skirt originally cost $10. How much will it cost if you sell it in Amazon with 25% mark-up price

san4es73 [151]

Answer:

$20.40

Step-by-step explanation:

20% off means that the new price of the skirt will be 80% of the original price:

$30(100% – 20%) = $30(80%)

Converting the percent to a decimal gives:

$30(0.8) = $24.00

There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:

$24(100% – 15%) = $24(85%)

Again converting the percent to a decimal gives:

$24(0.85) = $20.40

Oxana [17]

Answer:

Interest earned: $150.85

Total amount: $850.86

Step-by-step explanation:

Y=700(1.05)^4

Put the right side of the equation into a calculator and get

850.85 that's your total, so to get the amount earned subtract the original 700 from it and get 150.85
