How to work out Pythagoras Theoram​

Mathematics
1 answer:
Vlad [161]2 years ago

The Pythagorean Theorem works only with right angle triangles. There are three sides: Side A, Side B, and the hypotenuse.

The formula for the Pythagorean Theorem is: a^2 + b^2 = c^2

To find the answer (without the exponent), you should find the square root.

Now that we have the formula, let's apply it to a triangle:

90^2 + 95^2 = c^2 =

8100 + 9025 = 17125

Square root = 130.86252328302

130.86252328302 is the exact measure of the hypotenuse.

I hope this helped!

I need the answers for 1 a-d pleas ​
DaniilM [7]

We want to find a fraction that is between

\frac{1}{4}\:and\:\frac{1}{2}

There are several ways to go about this.

There are also infinitely many fractions that can be found between the given fractions.

Let us go for the one in the middle of the two fractions.

So we add the two fractions and divide by 2.

a) \frac{\frac{1}{4} +\frac{1}{2} }{2}

Find LCM for the numerator

\frac{\frac{1+2}{4}}{2}

Simplify:

\frac{\frac{3}{4}}{2}

\frac{\frac{3}{2}}{2}

\frac{3}{8}}

b) \frac{\frac{1}{3} +\frac{3}{4} }{2}=\frac{13}{24}

c)\frac{\frac{1}{2} +\frac{3}{4} }{2}=\frac{5}{8}

d)\frac{\frac{3}{5} +\frac{7}{8} }{2}=\frac{59}{80}

A newspaper article states that 90% of drivers in Iowa wear their seatbelt. Suppose we are interested in estimating the proporti
konstantin123 [22]

Answer:

The sample size is  n  = 3457

Step-by-step explanation:

From the we are told that

  The population proportion is  p =  0.90

  The margin of error is  E =  0.01  

From the question we are told the confidence level is  95% , hence the level of significance is    

      \alpha = (100 - 95 ) \%

=>   \alpha = 0.05

Generally the sample size is mathematically represented as

       n  =[  \frac{ Z_{\frac{\alpha }{2} }  }{E} ]^2 * p(1-p)

=>  n  =[  \frac{ 1.96  }{0.01} ]^2 * 0.90(1-0.90)

=>   n  = 3457

Starting at home, Omar traveled uphill to the gift store for 30 minutes at just 10 mph. He then traveled back home along the sam
hichkok12 [17]
I guess you want to find the average speed for the whole journey

average speed = distance travelled / time

the distance from home to the shop =   speed * time = 0.5*10 = 5 miles

time for travelling back =  distance / speed = 5/30 = 1/6 hours

average speed for whole journey = 10 / (1/2 + 1/6) = 10 *  3 / 2 = 15 mph
