Recall that using the pythaogorean theorem, which is only for right-triangles, the longest leg squared is the sum of the other two squared, namely c² = a² + b², now, if those units above are of a right triangle, then 25² = 7² + 24².
do they check out? if they do, then yes, you can make a right-triangle, if not, they nope.
Answer:
110 cm^2
Step-by-step explanation:
The area of the rectangle is 45 cm^2 (9 x 5) then add that to the area of the trapezoid ( ( 9+4 ) x 10 x 0.5 ) = 13x5 = 65 cm^2
65+45= 110 cm^2
You multiple lengthxwidthxheight and with those numbers it is 125
Answer:
50 50 one in 8
Step-by-step explanation:
The coin is a 50 50 and the dice in 2 in 8
Answer:
a = 20
Step-by-step explanation:
The mean is calculated as
mean = 
= 
= 
Then
= 27 ( multiply both sides by 5 to clear the fraction )
115 + a = 135 ( subtract 115 from both sides )
a = 20
