A water cooler holds 1,284 ounces of water. How many more 6 ounce glasses than 12-ounce glasses can be filled from the cooler
yawa3891 [41]
Answer:
- The water cooler can hold 214 of the 6-oz glasses because 1284 / 6 = 214

- The water cooler can hold 107 of the 12-oz glasses because 1284 / 12 = 107

- Because it is asking how many more glasses, you would do 214 - 107 = 107.

- You could also say that the water cooler can hold twice as many 6-oz glasses than 12-oz glasses.

Hope that helps! :)

Solve for g E=4gh How do you solve this equation
11111nata11111 [884]

Answer:

g = E/4h

Step-by-step explanation:

In order to solve for a variable, you have to isolate it from the other values on one side of the equation.

Because g is multiplied by 4 and h, undo this operation by dividing both sides of the equation by 4h.

\frac{E}{4h} = \frac{4gh}{4h} \\\\ \frac{E}{4h} = g

In the upcoming election for governor, the most recent poll, based on 900 respondents, predicts that the incumbent will be reele
lions [1.4K]
<h2>405 people</h2>

Step-by-step explanation:

It is given that there are a total of 900 people.

It is given that 55% of the people will reelect.

So,it can be found that 100-55=45% of the people may not reelect or may not make their decision yet.

So,number of people that may not reelect or may not make their decision yet is \frac{45}{100}\times 900=405.

So,405 people haven't made their decision yet or not reelect.

Integral of cosecx dx =log|tanx/2| show that.​
Pie

ANSWER:

Let t = logtan[x/2]

⇒dt = 1/ tan[x/2] * sec² x/2 × ½ dx

⇒dt = 1/2 cos² x/2 × cot x/2dx

⇒dt = 1/2 * 1/ cos² x/2 × cosx/2 / sin x/2 dx

⇒dt = 1/2 cosx/2 / sin x/2 dx

⇒dt = 1/sinxdx

⇒dt = cosecxdx

Putting it in the integration we get,

∫cosecx / log tan(x/2)dx

= ∫dt/t

= log∣t∣+c

= log∣logtan x/2∣+c where t = logtan x/2
