Nine out of 25 students finish their work early on Tuesday.What percentage of the class finish their work early?

Answers

9 is what percent of 25
= 9 / 25
= 0.36

Converting decimal to a percentage:
0.36 * 100 = 36%
36% of the class had finished their homework. 9/25 = x/100, 9 × 100 = x × 25, 900/25 = 25x/25 cross out the 25x/25 and divide 900 by 25 to get 36%

Amina sees a discount of 5% on a laptop. She can calculate the amount she has to pay for the laptop using the expression b – 5/100 b, where b is
the price of the laptop before the discount. If the price after discount is $494, which number from the set {500, 505, 510, 520, 525} is the value of b?

Answers

Answer:

The value of b is 520.

Step-by-step explanation:

Here, b represents the price of the laptop,

Since, discount percentage = 5 %,

So, the discount = 5% of b = (5b)/(100)

Thus, the price of laptop after discount = Original price of laptop - Discount

=b-(5b)/(100)

According to the question,

b-(5b)/(100)=494

(100b-5b)/(100)=494

(95b)/(100)=494

95b=49400

b=(49400)/(95)=520

Hence, the value of b is 520.
form an equation: b-5/100 b=494. 95/100b=494. 494*(100/95)=b b=520

The line plot below shows the lengths of strings Mario used for an art project.

Answers

Answer: B. 36 feet.

Number of strings = 8

Step-by-step explanation:

From , the given line plot, the number of strings used by Mario = Number of cross on the line plot

i.e. Number of strings used by Mario =  8

Now by the given line plot , the sum of all the observations will be ( multiply all values by their corresponding frequencies or crosses and add ) :-

1*1+2*1+3*1+4*2+7*2+8*1=36

Now, the total length of ribbon used by Mario = Sum of all the observations

Hence, the total length of ribbon used by Mario 36 feet.
