Pamela ran 7/10 mile on Tuesday and 3/8 mile on Thursday. How much fatter did she run on Tuesday ?

Len [333]

Answer:

$Difference = \frac{13}{40}$

Step-by-step explanation:

Given

$Thursday = \frac{3}{8}\ mile$

$Tuesday = \frac{7}{10}\ mile$

Required

How much farther is she on Tuesday

To do this, we simply calculate the difference between distance covered on both days.

$Difference = Tuesday-Thursday$

$Difference = \frac{7}{10} - \frac{3}{8}$

Take LCM

$Difference = \frac{28- 15}{40}$

$Difference = \frac{13}{40}$

<em>Hence, she ran 13/40 mile farther on Tuesday</em>

A box measures 3 1/2 ft by 1 1/3 ft by 2/14 ft what is the volume

asambeis [7]

Answer: 2/3^3

Step-by-step explanation:

To find the volume of a box, you use the formula, Lenth*Width*Height=Volume

The Lenth is 3 1/2. The width is 1 1/3 and the height is 2/14

Plug the values in formula

3 1/2*1 1/3*2/14

Covert the mixed numbers into imporper fractions so it is easier to solve

3 1/2=7/2

1 1/3=4/3

7/2*4/3*2/14

Reduce 2/14

2/14=1/7

7/2*4/3*1/7=7*4*1/(2*3*7)=28/42

Reduce 28/42=14/21=2/3

2/3 ft^3

Which special version of the Pythagorean Theorem can you use to find the length of any squares diagonal, d, using only the lengt

EleoNora [17]

The square's diagonal is the triangle's hypotenuse.

The Pythagorean theorem is = $a^{2}+b^{2}=c^{2}$

Here, 'c' is the hypotenuse and 'a' and 'b' are the two sides of the triangle.

As the side is given 12 inches, so this becomes

$12^{2}+12^{2}=d^{2}$

$144+144=d^{2}$

$d^{2}=288$

$d=\sqrt{288}$

$d=16.97$ inches
