Answer:

LMN is an acute triangle not right triangle

Step-by-step explanation:

by using pythagoras thoerem

a²+b²=c²

putting values

5²+13²=14²

25+169=194

194=196 so it is not a right angled triangle

if a²+b²=c² then it is right triangle

but if a²+b²<c² then it is acute triangle

Tessa bought stock in a restaurant for $278.00. Her stock is now worth $339.16. What is the percentage increase of the value of

Natasha2012 [34]

The percentage increase of the value of Tessa's stock is 22%

Step-by-step explanation:

The percentage of increase = $\frac{New-old}{old}$ × 100%, where:

New: is the value after increasing
Old: is the value before increasing

Tessa bought stock in a restaurant for $278.00.

Her stock is now worth $339.16

We need to find the percentage of increase of the value of

Tessa's stock

∵ The initial value of the stock = $278.00

∴ The value of the stock after increasing = $339.16

- Substitute these values in the rule above

∴ The percentage of increasing = $\frac{339.16-278}{278}$ × 100%

∴ The percentage of increasing = 0.22 × 100%

∴ The percentage of increasing = 22%

The percentage increase of the value of Tessa's stock is 22%

38 is what percent of 76?

djyliett [7]

Okay, to find the answer, you would divide the first number by the second number.

38/76=0.5

To find the decimal as a fraction, move the decimal two spots to the right.

0.5=50%

I hope this helped!
