Tanyss's house has 25 windows. Her brother has washed 22 of the windows. What percent of the windows has her brother washed?
Sunny_sXe [5.5K]

88%


22÷25=0.88 then convert to percent by doing 0.88×100 and adding the % sign


Alternatively you could do 100÷25 to get 4 then do 22×4 to get 88

Anna, ben, and cindy have m markers together. anna has a markers, and this is twice as many markers as ben has. how many markers
SOVA2 [1]
So, Anna has a markers, Ben has b markers and Cindy has c markers. 
We know that a+b+c = m.
And we know also that a = 2b. (<span> twice as many markers as ben has</span>)
(Remember b is the number of Ben markers.)
The equation becomes:
2b+b+c=m.
Solving for c:
c=m-3b
Cindy has (m-3b) markers.

I need help with this pls

I'll explain it simply for you

1st question
Of course you know phythagoras theorm
You even wrote it up there
It states that the sum of the square of the two sides of an equilateral triangle is equal to the square of the hypotenuse
{a}^{2}  +  {b}^{2}   =  {c}^{2}
Where C is the hypotenuse
*NOTE* :
HYPOTENUSE is the greatest side in a triangle!!
And that's where your mistake is!
So you should take the greatest side as C
So in Q3. 7, 24 and 26 are the given numbers
You'll make the smaller two numbers a and b and the greatest number C
Using the Formula you'll solve the left side first which is
{a}^{2}  +  {b}^{2}
Then the right side which is
{c}^{2}

And if both are equal then it is a right triangle otherwise it isn't!
Let
a=7
b=24
c=26


a^2 + b^2
7^2 + 24^2
49 + 576 = 625
GREAT, Now the right side

26^2 = 676
Since they aren't equal it isn't a right angled triangle...

Then let
a=7.5
b=10
c=12.5

7.5^2 + 10^2
= 56.25 + 100
= 156.25



12.5^2 = 156.25

They are EQUAL
Therefore it is a right triangle too

Hopefully I helped
