Last week f40 fifth graders went on a field trip to the science museum

Xelga [282]

8 out of 40 fifth graders went to see the lab animal presentation. This can be written as this expression:

$\frac{8}{40}$

Find the greatest common factor of 8 and 40:

Factors of 8: 1, 2, 4, 8
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

Therefore the greatest common factor is 8. Divide both the numerator and the denominator by 8.

$\frac{8}{40} = \frac{8/8}{40/8} = \frac{1}{5}$

Therefore the fractional part is $\frac{1}{5}$ .

To get the percentage, you need to get the denominator to a value of 100.

To do so, you need to find the value to multiply both the numerator and denominator by to achieve this.

To get this value, you can divide 100 by the denominator of the fractional value.

$100 / 5 = 20$

Then you can multiply both the numerator and denominator by 20:

$\frac{1}{5} = \frac{1 * 20}{5 * 20} = \frac{20}{100}$

From here, the numerator will state the percentage:

$20\%$

Hope this helps :)

Devon bought running shocs at a price that was 1/4 off the original price of $88. He paid a sales tax of 7% on

larisa86 [58]

The correct answer is C. $ 9.38

Explanation:

The first step to solve this mathematical problem is to know the price of the shoes. About this, we know the price is 1/4 of $88 plus taxes. You can find how much is 1/4 of $88 by following this process:

1. Write the amounts given

$\frac{1}{4}$ of $88$

2. Divide the number by the denominator (bottom number) and then multiply by the numerator

$88$ ÷ $4 = 22$

$22 x 1 = 22$

This means the discount was $22 and $88- $22 = $66, which is the price with the discount. Now, it is necessary to add the sales tax, which can be done by finding the 7% of $66 and adding this number to $66 (the price of the shoes including the 1/4 discount)

1. Write the values

66 = 100 (66 represents the total or 100%)

x = 7 (7% is the value you want to know and the x represents the value is not known)

2. Cross multiply

x 100 = 462

3. Find x

x = 462 ÷ 100

x = 4. 62 ( value of taxes)

Now, add the taxes to the price $66 + $ 4.62 = $70.62 (price with taxes). Finally, we know Devon paid using four $20 bills. This means he gave the clerk $80 ($20 x 4 = $80). Finally, to know how much is the change subtract the price of the shoes from the money Devon gave the clerk $80 - $70.62 = $9.38

Which quantity is given by the constant term ?

Marrrta [24]

The general equation of a line in slope-intercept form is:
y = mx + b
where m is the slope and b is the constant term.
If x is put equal to zero the equation becomes:
y = b
therefore the constant term b is the intercept on the y axis, or the y-intercept.
