How to convert 4.5 into a decimal
stiks02 [169]
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

Will a stand that can hold up to 40 pounds support a 21 kilogram television
shtirl [24]
If you would like to know if a stand will support a 21-kg television, you can find this using the following steps:

1 kilogram = <span>2.20462262 pounds
1 kilogram = 2.2 pounds

21 kilogram = 21 * 1 kilogram = 21 * 2.2 pounds = 46.2 pounds
46.2 pounds > 40 pounds

The correct result would be: No, the stand won't support a television.</span>

4/5z=16 solve equation (that's a fraction )
Assoli18 [71]
So we need to isolate the variable. In order to do that, we need to multiply both sides by 5/4.
Why? That's so that 4/5z will be canceled out when multiplied by 5/4 to get just z.
And so, we would get 20 as our answer.

To find the height of a pole, a surveyor moves 150 feet away from the base of the pole and then, with a transit 4 feet tall, mea
ladessa [460]

Answer: The answer is 139 feet

H = height of the pole =?

BC = ED = height of the transit = 4 ft

CD = BE = distance moved away from the base of the pole = 140 ft

Consider the ΔABE

tan44 = AE/BE

tan44 = h/140

h = 140 tan44

h = 135.2 ft

H = height of pole = AE + ED = h + ED = 135.2 + 4

H = 139.2 ft

PLEASE HELP ASAP! I need the answer for this question anyone ?
Alexxandr [17]

Answer:

A: sqrt(11)

B: 4.2

C: sqrt(26)

Step-by-step explanation:

First, 4^2 = 16

That means that sqrt 11 is smaller than 4.2 (a value greater than 4). This is because sqrt16>sqrt11.

Sqrt(26) is greater than sqrt(25) = 5. That means that it's greater than 4.2.

Hence, the order given above.
