The total amount in dollar that the painter charged for painting the room is 325 dollars because 25 times 13 equal 325 dollars.
Use Power of a point.
(can prove using similarity of the triangle)
AC*CB = DC*CE
8*7 = 4*CE
CE = 14
DE = DC+CE = 4+14 = 18
Ans: 18
Answer:
The improve in speed is 3.9334 words/min
Step-by-step explanation:
we will find speed at both occasions and then we can subtract them
First test:
total number of word =694
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
Second test:
total number of word =753
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
So, improve in speed is
word/min
Answer:
c
Step-by-step explanation:
c. j = a + 5
such that 7 = 2 +5
Answer:
Step-by-step explanation:
we know that
The Pythagorean Theorem states that in a right triangle
where
c is the greater side (the hypotenuse)
a and b are the legs
In this problem
Let
c=AB ---> distance from point A to point B
a ---> the difference of the x-coordinates both points
b ---> the difference of the y-coordinates both points
so
substitute
