The given :right angled triangle
:there are two equal sides
solution
1 if triangle name is ABC
then AB=AC
then triangle ABC is a isosceles triangle
then angle BAC =angle CBA =2X
and any triangle in life there angles sum =180
2x + 90 = 180
2x=180-90
2x=90
$x = \frac{90}{2}$
x=45

If 10 of the 50 apples are green than what percent of the apples are green

Andrew [12]

So the question here is just simply what percentage is 10 out of 50 correct? You would basically just do 10/50 times 100 which will give you 20 percent as your answer.

Can u please answer this question

Paha777 [63]

One Way:
We can change the mixed number to a decimal for comparing.

$1\frac{1}{4}$ m = $\frac{5}{4}$ m = 1.25 m

1.4 m    > 1.25 m
Darren   >   Luke

Darren's jump was higher by (1.4-1.25) 0.15 m

Or another way change the decimal to a fraction and the mixed to an improper fraction too.

$1\frac{1}{4}$ = $\frac{5}{4}$ (Luke)
1.4 = $\frac{7}{5}$ (Darren)
We need a common denominator to compare
$\frac{5*5}{4*5}$ (Luke)
$\frac{7*4}{5*4}$ (Darren)
$\frac{25}{20}$ (Luke)
$\frac{28}{20}$ (Darren)

$\frac{28}{20} > \frac{25}{20}$
  Darren >    Luke

By:
$\frac{28}{20}$ - $\frac{25}{20}$ = $\frac{3}{20}$
Which is also by 0.15 m
Darren jumps higher and by 0.15 m

Aryana simplified the expression 3(x + 4) + 2(2x – 3). She justified her work by letting x = 3 in both the given and simplified

Artemon [7]

Answer:

7x+6

Step-by-step explanation:

Aryana simplified the expression 3(x + 4) + 2(2x – 3). She justified her work by letting x = 3 in both the given and simplified expressions. Which is the correct simplified expression for Aryana's expression? What is the result for both expressions when x = 3?

Simplified Expression:

3(x + 4) + 2(2x – 3)

3x+12+2(2x-3)

3x+12+4x-6

7x+6

How would you write this equation in terms of sin and cos as well as simplify it from there?

ziro4ka [17]

Try this option:
$(1+ \frac{cosx}{sinx})(1- \frac{cosx}{sinx})- \frac{1}{sin^2x}= \frac{sin^2x-cos^2x}{sin^2x}- \frac{1}{sin^2x}=$
$= \frac{sin^2x-cos^2x-sin^2x-cos^2x}{sin^2x}=- \frac{2cos^2x}{sin^2x}.$
or -2ctg²x

Rosie washes clothes for two families the first family pays her $500 more per month than the second. Her total earning per month

disa [49]

Answer:

Family 1: $1.850
Family 2: $1.350

Step-by-step explanation:

We know that the total monthly payment is 3200, so if we call Pa (family A`s payment) and Pb (Family B's payment) the payments:

Pa+Pb=3200
also, Pa = Pb+500

So if we replace Pa in the first ecuation:

Pb+500+Pb=3200
2Pb= 3200-500
Pb=2700/2= $1.350

then Pa+Pb=3200 => Pa= 3200-1350= $1.850

Good Luck!
