Step-by-step explanation:
we know that
The legs of a 45°-45°-90° triangle are congruent
Let
x ----> the length of one leg of the triangle
Applying the Pythagorean Theorem

where
c is the hypotenuse
a and b are the legs
we have


substitute

Answer:
1. The fraction is 11/9
Step-by-step explanation:
You didn't specify which ones you need help with so I'm answering the first one for you.
let x=1.2 —equation 1
10x=12.2 —equation 2
subtract equation 1 from 2
10x-x=12.2-1.2
9x=11
x=11/9
Step-by-step explanation:
The equation of the line with a slope of 0 is y=c, where c is a constant.
As the line passesvthrough a pt with a y coordinate of 9, the equation is y=9.
You already have all you need. Just put in it the slope-intercept form: y=mx+b where m is the slope and b is the y-intercept so
y=7x-4
I believe you meant milliliters. If so the answer is 1500ml
2 liters = 2000ml
2000/4 = 500 for 1/4
We need 3/4 so we multiply 500 X 3 and get 1500ml
