A.
13%

B.

C.
6%

D.

Answers

Question: What is 35 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$40=100\%$40=100%​.

Step 4: Similarly, $x=35\%$x=35%​.

Step 5: This results in a pair of simple equations:

$40=100\%(1)$40=100%(1)​.

$x=35\%(2)$x=35%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{40}{x}=\frac{100\%}{35\%}$
40
x​=
100%
35%​​

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{35}{100}$
x
40​=
35
100​​

$\Rightarrow x=14$⇒x=14​

Therefore, $35\%$35%​ of $40$40​ is $14$ B. 14%

From Least to Greatest :

-20 3/4

-15 1/2

-14 3/4

-1/4

Step-by-step explanation:

We have four fractions those of which are negative, meaning this question works a bit differently than how most least to greatest questions would work by. When dealing with negatives, you have to go backwards, or in other words, the highest number would be the least and the lowest number would be the greatest. This is due to the negative rule, that it's sort of like fighting to zero first than instead of fighting to a great and huge number. With this information, we can answer our question.

-20 3/4 is the highest number, but since we are dealing with negatives it is more far from zero, therefore making the least greatest.

Following up with -15 1/2 , its closer but not as close to the other two numbers.

Now with -14 3/4, getting closer, but not close enough as :

-1/4. This is the closest to zero, therefore it is the greatest number out of the three.

You now have your order.

Andre rode his bike at a constant speed. He rode 2 1/3 miles in 11 2/3 minutes.

(a) Write an equation that represents the distance d he rides (in miles) after time t (in minutes) passes.
(b) How long will it take Andre to ride 4 2/5 miles?

Answers

Given that Andre rode his bike at a constant speed.
Number of miles driven = 1 mile
Time taken to drive 1 mile = 5 minutes.
Then speed can be calculated using formula:
Speed = Distance / Time


Now we have to find the amount of time t (in minutes) taken by him to right distance d so we can again use same formula.

Speed = Distance / Time
or
Time = Distance / Speed
Plug the given values

t = 5d
