This is an algabraic problem, so we would use variables:
Length=x
Width=y
The length is four times the width, so
x=4y
Since the equation for perimeter is P= 2(x+y), you would instead substitute 4y for x, and 7 for the perimeter.
7=2(4y+y)
Simplify.
7=2(5y)
7=10y
y=7/10
Since y is 7/10, you would substitute 7/10 into the equation x=4y.
x=4(7/10)
x=14/5
So, the dimensions are 7/10 x 14/5.
Hope this helps!
Answer:
For longest x = 6.4
For shortest x = 3
Step-by-step explanation:
Given a right angle triangle with lengths 4 units and 5 units and x units .
x can be gotten using Pythagoras theorem .
If x Is the longest side , then
x^2 = 5^2 + 4^2
= 5x5 + 4x4
= 25 + 16
x^2 = 41
x = squared root of 41
x = 6.4
If x is the shortest side ,
x^2 = 5^2 - 4^2
= 5x5 - 4x4
= 25 - 16
x^2 = 9
x = squared root of 9
x = 3
He will burn 225 calories. if you divide 150/20 it will equal 7.5 then multiply 7.5 by 30 and you’ll get 225
Answer:
30% because the chance of the whole dice is 6
