(this is my sister on my acc I'm letting her) True or False? When you use a pulley you use less force to pull up a load.Explain

natta225 [31]

Answer:

True depending on what you are comparing it to.

Step-by-step explanation:

A pulley would help lighten the load that you are trying to pull up, which may make it easier for you to get the load to your designated area. The more complicated it is, usually the more 'lighter' it becomes, or the less force you have to exert.

For example, you will have to give a 100% energy in trying to life a heavy box. However, if you use a simple pulley (only one), you may only have to exert 75% more energy, for the weight is significantly lower.

8. Sven sells hamburgers at a ballpark. He earns $14.50/h, plus $0.50

Komok [63]

Answer:

Part A: $55.50

Part B: 52 hamburgers(sorry if I am wrong for part b but I think it is right)

Step-by-step explanation:

Part A: $14.50 x 3= $43.50 + 24 x $0.50= $12=

($ earned per hrs x hrs worked)+ ($ per hamburger sold x times amount)

Hence $43.50 + $12= $55.50.

Part B: $14.50 x 6.5 = $94.25 $120 - $94.25= $25.75

($ earned per hrs x hrs worked x x hrs worked) ($ earned - $ earn from shif

$25.75/0.50=51.5 (51.5 rounded to nearest burgers is 52 burgers)

Hence answer is 52 burgers.

a student found the slope of a line that passes through the points (1,14) and (3,4) to be 5. what mistake did she make?

mariarad [96]

$x_{1}=1$
$x_{2}= 3$
$y_{1} =14$
$y_{2}=4$
$Slope= \frac{rise}{run} = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } = \frac{4-14}{3-1} = \frac{-10}{2} =-5$

answer: The student flipped the y values

Sandra's scores on the first 4 tests were 87%, 92%, 76%,and 89%. What is the minimum score she needs to make on the fifth test s

sergejj [24]

Answer:

Sandra need to score at least <u>56%</u> in her fifth test so that her average is 80%.

Step-by-step explanation:

Given:

First 4 test scores = 87%, 92%, 76%,89%

Average targeted = 80%

We need to find the minimum score she needs to make on fifth test to achieve average of at least 80%.

Solution:

Let the minimum score she needs to make in fifth test be 'x'.

Total number of test = 5

Now we know that;

Average is equal to sum of all the scores in the test divided by number of test.

framing in equation form we get;

$\frac{87+92+76+89+x}{5}=80$

Multiplying both side by 5 we get;

$\frac{344+x}{5}\times 5=80\times 5\\\\344+x=400$

Subtracting both side by 344 we get;

$344+x-344=400-344\\\\x=56\%$

Hence Sandra need to score at least <u>56%</u> in her fifth test so that her average is 80%.
