Answer:
Paul might have written the expression
.
Step-by-step explanation:
Given:
Length of the leg 1 = a
Length of the leg 2 = b
Hypotenuse = h
We need the expression Paul has written:
Solution:
Now we know that;
The figure sketched by Paul is a right angle triangle.
Now by Pythagoras Theorem which states that;
"The square of the length of the hypotenuse is equal to sum of the square of the length of the legs."
equation can be framed as;

Hence Paul might have written the expression
.
Answer:
Acute triangle
x = 3
GH = 19
Step-by-step explanation:
Answer:
a summary is an average and an average is mean
Step-by-step explanation:
to get the mean add all the cakes sold together then divide by number of years
21+28+19+26+21=115
115/5=23
so....
first one: mean
second one: 23
Answer:
The ratio between two values A and B is just the quotient between these two values:
ratio = A/B
a) $280 in 7m
Here the ratio is:
$280/7m = $40/m
This also can be read as:
$40 per meter.
b) 105 miles in 2 hours
Here the ratio is:
105mi/2h = 52.5 mi/h
This also can be read as:
52.5 miles per hour
c) $33 for 5lb
The ratio is:
$33/5lb = $6.6/lb
This can be read as:
$6.6 per pound.
d) 50 pages in 2 hours
the ratio is:
(50 pages)/2h = 25 pages/h
this can be read as:
25 pages per hour.
