Answer
Step-by-step explanation:
Both 1 and 2 equel up to 90 degrees
so to find x for 1 and 2 you would simplify the equations
90 = 6x - 3
and
90= 3x - 6
simplify them and you wil get the answers you want
another way to do it is combining the two and solve.
90 = 9x - 9
Just simplify :)
The formula of the area of a triangle:
b - the bash - the height
We have:
b - the base3b - the height486 - the area
Substitute:
Answer: The length of the height is equal 54 units.

Answer:
(78, 80)
Step-by-step explanation:
Given a normal distribution :
Mean = 79 seconds
Standard deviation = 0.5 seconds
Using the empirical rule :
95% of her finishing times :
According to the empirical rule, 95% represents 2 standard deviations from the mean that is ± 2 standard deviations from the mean score or value.
Hence ;
The interval will be defined as ;
Mean ± 2(standard deviation)
79 ± 2(0.5)
79 ± 1
(79 - 1) ; (79 + 1)
78 ; 80
To find the base area of a pyramid, you can use the equation:
volume = base area × height
volume = 10 × 9
volume = 90 cubed inches
