The Westminster Widget Company has an old machine that can produce 24 widgets in three hours. Now they have purchased a new
machine that can produce 48 widgets in four hours. Working together, how long will it take the two machines to produce 120
widgets?

Answers

Answer 1

9514 1404 393

Answer:

  6 hours

Step-by-step explanation:

The old machine produces widgets at the rate of ...

  (24 widgets)/(3 h) = 8 widgets/h

The new machine produces widgets at the rate of ...

  (48 widgets)/(4 h) = 12 widgets/h

The total rate of production of the two machines is ...

  (8 +12) widgets/h = 20 widgets/h

Then the time required to produce 120 widgets is ...

  (120 widgets)/(20 widgets/h) = 6 h

Working together, the two machines can produce 120 widgets in 6 hours.

Explanation: How i got it was by first looking at what Eric’s weight loss program, I then guessed he lost about the same amount of weight each week (1.5), i then did that times 4 since that’s how many weeks were recorded on the chart which gave me 6. I then looked at the chart again and saw that Ed first started with the weight 205 and by week 4 his weight was 197, I then did 205-197 which equals 8, I then decided that Ed lost more weight.

Answers

Answer: 10 minutes

Step-by-step explanation:

x·1/20 + x·1/25 + x·1/100 = 1

Multiply each term by 100 to clear the equation of all fractions

100x/20 + 100x/25 + 100x/100 = 100

5x + 4x + 1x = 100

10x = 100

x = 10

The answer is 10 minutes

if ABCD is a rectangle find angle ABD​

Answers

Answer:

61 degrees

Step-by-step explanation:

First, find x. CBD=BDA

x+18=4x-15

x=11

Four interior angles of a rectangle are all 90 degrees. So to find ABD, subtract  CBD from 90 degrees. So 90-29=61 degrees.

Find the value for x and y if x+(xy)^1/2+y=14 and x^2+xy+y^2=84​

Answers

Answer:

[tex]xy = 4 [/tex]

Step-by-step explanation:

Taking the first equation , we have ,

[tex]\implies x + (xy)^{\frac{1}{2}} + y = 14 \\\\\implies x + \sqrt{xy}+ y = 14 \\\\\implies x + y = 14 -\sqrt{xy}\\\\\implies (x+y)^2 = (14-\sqrt{xy})^2 \\\\\implies x^2+y^2+2xy = 196 + xy -28\sqrt{xy} \\\\\implies x^2+y^2+xy = 196 - 28\sqrt{xy}[/tex]

Now according to second equation,

[tex]\\\\\implies 84 = x^2+xy+y^2 [/tex]

Plug on this value ,

[tex]\implies 84 = 196 -28\sqrt{xy}\\\\\implies -112 = -28\sqrt{xy}\\\\\implies \sqrt{xy}=\dfrac{112}{28}\\\\\implies \boxed{\boxed{ xy = 16 }}[/tex]

On substituting this value in terms of one variable of the equation you can get the values of x and y .

Answers

Answer:

Z = 80 degrees and X = 8 degrees

Step-by-step explanation:

The reason Z = 80 degrees is because a flat line always has a measure of 180 degrees.

I forget the term, but we know that 6x + 52 is equal to 100 due to some angle theorem. (Once again, I do not remember the term.)

We then subtract 52 from 100 to get the equation 6x = 48. Divide them both by 6 and you get X = 8!

I have ¾ of an hour to finish 6 homework assignments. How much time can I spend on each assignment?

Answers

Answer:

 7.5 min for each assignment

Step-by-step explanation:

1 hour is 60 minutes, and there are four 15 minute intervals. So, if there are four intervals of 15 minutes that add up to 60, just take three of them and put them over four:

15 ⋅ 15⋅ 15/ 15⋅ 15 ⋅ 15 ⋅ 15= 45 /60

Or we could multiply one hour, or 60 minutes, by  3 /4 .

    60 ⋅ 3/ 4 = 60 /1 ⋅ 3 /4 = 60 ⋅ 3/ 4 ⋅ 1 = 180 /4 =45

Three fourths of an hour is 45 minutes.

to find  time for each assignment =45/6

          7.5 min

[tex]\beta =[/tex] the subtended angle

Required

Find [tex]\beta[/tex]
