This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.
Answer:
x=15.75 y=59
Step-by-step explanation:
In total there is 360 degrees. We know y is 59 so we will replace it with that.
59+59=118. 360-118=242. 242/2=121. 29+29=58. So we can subtract that to equal 63. Now 63=4x. We can divide so 2x=31.5. x=15.75.
Therefore, 15.75=x and 59=y
I hope this helped ^^.
Answer:
(-2,3)
so the a answer is -2 on the x axis
Answer:
the given value x=13 is not a solution of the inequality
Step-by-step explanation:
we first need to solve this inequality (can treat the inequality like a normal equation to solve it)
5x-17 > 62
5x > 79
x>(79/5)
keep in mind that (79/5)=15.8
so x needs to be bigger than 15.8 in order to satisfy this inequality.
since 13<15.8 when x=13 it does not satisfy the inequality
therefore the given value x=13 is not a solution of the inequality
Averaging formula:
A=sum of n values / n
Substitute the variables,
c is the average,
a and b are the test scores
∴

rearrange for b
