The small piston of a hydraulic press has an area of 2.0 cm^2 and the large piston has an area of 16 cm^2. If the small piston has a force of 4.0 N applied to it, the output force of the large piston is ____? A.) 0.50 N B.) 2.0 N C.) 8.0 N D.) 32 N

Answers

Answer:

32N

Step-by-step explanation:

Given data

A1= 2cm^2

A2= 16cm^2

F1= 4N

F2=???

Applying the formula

Presure= force/area

P=F/A

F1/A1=F2/A2

substitute

4/2= F2/16

cross multiply

F2= (16*4)/2

F2= 64/2

F2= 32N

Hence the output force is 32N

The bases of a trapezoid lie on the lines y=2X +7 and y= 2X -5. Write the equation that contains the midsegment of the trapezoid

Answers

Given:

The bases of a trapezoid lie on the lines

[tex]y=2x+7[/tex]

[tex]y=2x-5[/tex]

To find:

The equation that contains the midsegment of the trapezoid.

Solution:

The slope intercept form of a line is

[tex]y=mx+b[/tex]

Where, m is slope and b is y-intercept.

On comparing [tex]y=2x+7[/tex] with slope intercept form, we get

[tex]m_1=2,b_1=7[/tex]

On comparing [tex]y=2x-5[/tex] with slope intercept form, we get

[tex]m_2=2,b_2=-5[/tex]

The slope of parallel lines are equal and midsegment of a trapezoid is parallel to the bases. So, the slope of the bases line and the midsegment line are equal.

[tex]m=m_1=m_2=2[/tex]

The y-intercept of one base is 7 and y-intercept of second base is -5. The y-intercept of the midsegment is equal to the average of y-intersects of the bases.

[tex]b=\dfrac{b_1+b_2}{2}[/tex]

[tex]b=\dfrac{7-5}{2}[/tex]

[tex]b=\dfrac{2}{2}[/tex]

[tex]b=1[/tex]

So, the y-intercept of the required line is 1.

Putting m=2 and b=1 in slope intercept form, we get

[tex]y=2x+1[/tex]

Therefore, the equation of line that contains the midsegment of the trapezoid is [tex]y=2x+1[/tex].

9. In a home economics class, 6 girls worked together and sewed a dress in 4 days. How long
would it have taken for 4 girls to make the same dress?​

Answers

Answer:

6 days.

Step-by-step explanation:

Given that in a home economics class, 6 girls worked together and sewed a dress in 4 days, to determine how long it would have taken for 4 girls to make the same dress, the following calculation must be performed:

X / 6 = 4

X = 4 x 6

X = 24

24/4 = 6

Thus, the 4 girls will take 6 days to make the same dress that 6 girls made in 4 days.

Elena is ordering dried chili peppers and corn husks for her cooking class. Chili peppers cost $16.95 per pound and corn husks cost $6.49 per pound.

Elena spends less than $50 on d pounds of dried chili peppers and h pounds of corn husks.

Can Elena purchase 1.5 pounds of dried chili peppers and 3 pounds of corn husks and spend less than $50? Explain your reasoning.

Answers

Yes she can. If she buy 1.5 pounds of dried chili peppers and 3 pounds of corn husks they will cost $45 so yes she will spend less than $50

Yes, Elena purchase 1.5 pounds of dried chili peppers and 3 pounds of corn husks and spend less than $50.

What is the reference as the equation?In its most basic form, an equation is an assertion that demonstrates that two formulas are equal. 63x + 5 = 14, for example, is an equation wherein 63x + 5 and 14 are two representations separated by a 'equal' sign.

For the given question;

Let the pounds of dried chili peppers be 'd'.Let pounds of corn husks be 'h'.Chili peppers cost $16.95 per pound Corn husks cost $6.49 per pound.

The equation becomes;

16.95 d + 6.49 h

16.95 (1.5) + 6.49 (3)

  25.425 + 19.47

        44.895 < $50

Thus, Elena purchase 1.5 pounds of dried chili peppers and 3 pounds of corn husks and spend less than $50.

A farmer need five men to clear his farm in 10 days how men will he need, if must finish clearing in 2 days if they work at the same rate

Answers

Answer:

1 person  

Step-by-step explanation:

It is given that a farmer wants 5 persons to complete a work of clearing his field in ten number of days.

We have to find out the number of persons required if the farmer needs to clear his field in 2 number of days.

Therefore according to the information given :

10 days = 5 persons

∴ 1 day = [tex]$\frac{5}{10}$[/tex] persons

So  2 days = [tex]$\frac{5}{10}\times 2$[/tex] persons

                 [tex]$=\frac{5}{5}$[/tex] person

                 = 1 person

A baseball team had 75 players show up for tryouts last year and this year had 90 players show up for tryouts. Find the percent increase in players from last year to this year.

Answers

Answer: 33.3%

Step-by-step explanation:

First find the difference between the players in try-outs over the years.

= 90 - 75

= 25

Then use this difference to find the percent increase:

= Difference / Players last years * 100%

= 25 / 75 * 100%

= 33.3%

If x and y vary directly and x=25 when y=100 find x when y=24.
PLEASE HELP FASTTTTTTT

Answers

Answer:

x = 6

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 25 when y = 100 , then

100 = 25k ( divide both sides by 25 )

4 = k

y = 4x ← equation of variation

When y = 24 , then

24 = 4x ( divide both sides by 4 )

6 = x

Answers

Answer:

186.7 cubes

Step-by-step explanation:

How many LaTeX: \frac{1}{3}1 3 inch cubes does it take to fill a box with width LaTeX: 2\frac{2}{3}2 2 3 inches, length LaTeX: 3\frac{1}{3}3 1 3 inches, and height LaTeX: 2\frac{1}{3}2 1 3 inches?

Step 1

We find the volume of the box

= Length × Width × Height

Length = 3 1/3 inches = 10/3 inches

Width = 2 2/3 inches = 8/3 inches

Height = 2 1/3 inches = 7/3 inches

The volume of the box =

10/3 inches × 8/3 inches × 7/3 inches

= 560/9 cubic Inches

= 62 2/9 cubic inches

Step 2

How many 1/3 inch cubes would fill the box.

This is calculated as:= 62 2/9 cubic inches/ 1/3 inches

= 560/9 ÷ 1/3

= 560/9 × 3/1

= 186.66666667 cubes

Approximately = 186.7 cubes

I do not particularly enjoy belonging to clubs; I greatly prefer doing things with only a few friends or even just spending time alone. Still, they are my best friends, and I do like our town, so I agreed very reluctantly to go. 2 We live in Mount Dora, which is the proud possessor of one high school, one middle school, two elementary schools, a well-used library, a thriving downtown district, and a handsome new community center. It was the new community center that had created my problem. The director had decided that sponsoring a service club for teens would be a splendid idea. It was my misfortune that the director is Kristina's very enthusiastic aunt. And so it was that I, along with approximately two dozen other misguided souls, attended the organizational meeting for the Dora Do-Gooders. I had explained to Kristina that I would attend the first meeting as a show of support for her aunt but that under no circumstances would I commit myself to doing anything more than that. Therefore, I was stunned to receive an e-mail from Mrs. Maguire that thanked me profusely for signing up to be a part of the first major undertaking of the club, an entire Saturday devoted to service projects for citizens who needed help. 3 I glared at Kristina reproachfully throughout our first-period Spanish class the next morning. She had responded to none of my calls or texts nor my outraged e-mail, and this morning she studiously avoided meeting my eyes, doubtlessly glad that the alphabetical seating arrangement meant that she was across the room from me. I also noticed that she had entered class at the last possible moment and that Joel was also trying to catch her eye. I grinned a little at that. 4 The results of my confrontation with her after class were unsatisfactory. Kristina apologized but then shrugged, adding, "What could I do? She's my aunt, and she needed volunteers for next weekend. I had to help her." 5 I was about to say that Kristina could help her all that she wanted but to leave me out of it when Joel grudgingly said that he would help. Mrs. Maguire had tutored him in algebra and had been very kind about it, so he supposed he could give up one weekend to help. I felt no such obligation but being rude would not be wise. After all, math is not my strong suit either. Who knew when I might need Mrs. Maguire's help?
