Background For Teachers: Our place value system is based on a pattern of tens. Each place value increases ten times the value of the place to its right. We use the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 to write any whole number. The symbols are called digits

Lindsay prepared 9 containers of fruit punch for a party. After the party, there were still 4 4/9 containers of fruit punch left

umka2103 [35]

Turn 9 into $\frac{81}{9}$ . Then, convert 4 $\frac{4}{9}$ into a improper faction ( $\frac{40}{9}$ ). Then, subtract

$\frac{81}{9} - \frac{40}{9} = \frac{41}{9}$ . Lastly, convert $\frac{41}{9}$ to a mixed fraction ( $4\frac{4}{9}$ ).

Your answer is $4\frac{4}{9}$ .

Dr. Nefario put $5000 in the bank and left it there for 6 months. What simple interest rate would he need to have in order to ha

Sonja [21]

Answer: The interest rate is .166%

Step-by-step explanation:

So what I did was divide $50(Amount at the end) by 6 (the number of months). Which would give me the amount of money he made per month ($8.333...). So then $8.333.../$5000(Total $) is .166...% (Interest rate)

Pls help, I really need this answer!!!!

If you think about it, an octagon is made up of 8 triangles. So you first find the area of one triangle then multiply it by 8 for the total area:
A=1/2bh
A=1/2(9.9)(12)
A=59.4

59.4 x 8= 475.2

Therefore the total area for the octagon should be 475.2 units^2

Hope this helps !

How are the solutions to the following two equations related m+5=72 <br> m+72=5

EastWind [94]

To see how they are related, let us solve the two equations.

FIRST EQUATION

$m + 5 = 72$

$\rightarrow \: m = 72 - 5$

$\rightarrow \: m = 67$

SECOND EQUATION

$m + 72 = 5$

$\rightarrow \: m = 5 - 72$

$\rightarrow \: m = - 67$

Hence the solutions to the two equations are ADDITIVE INVERSE of each other.

59:26 What is the length of the hypotenuse, x, if (20, 21, x) is a Pythagorean triple? 22 29 41 42

Vikki [24]

If the legs are length a and b and hyptonuse is c then
a²+b²=c²

so
if the legs are 20 and 21 and the hypotnuse is x then
20²+21²=x²
400+441=x²
841=x²
29=x
