Mathematics

Stella [2.4K]3 years ago
8 0

We are given

isosceles triangle

and when we draw perpendicular on third sides , it will divide third sides into two equal parts

so,

opposite =38

adjacent =x/2

hypotenuse =43

now, we can use Pythagoras theorem

38^2+(\frac{x}{2})^2=43^2

now, we can solve for x

\left(\frac{x}{2}\right)^2=405

x=18\sqrt{5}............Answer

A snake slithers 2/9 miles in 4/5 hours what is its speed in miles per hour
Mamont248 [21]

Answer:

5/18

Step-by-step explanation:

speed = distance / time

s = (2/9 miles) / (4/5 hours)

To divide by a fraction, multiply by the reciprocal:

s = (2/9) × (5/4)

s = 10/36

s = 5/18

So the snake's speed is 5/18 miles per hour.

a school cafeteria makes cheese sauce for macaroni using 15 cups of Swiss cheese and 17 cups of cheddar cheese Perry tries to ma
deff fn [24]

No, Perry is not using the correct ratio, because 15:17 is not equivalent to 5:7

15 divided by 3 is indeed 5 but divided 17 by 3 does not give you 7, nor a whole number.



I hope this helps.
