The answer is 7/10 because the even values are 2,4,6, and the others are 7,8,9,10. Added together, it adds up to 7/10
Answer:
The length of the legs is 8.64cm and 14.64cm respectively
Step-by-step explanation:
I've added an attachment to aid my explanation.
At different intervals, I'll be making reference to it.
Given



From the attachment, we have:

Since, M is the Midpoint

Substitute 17 for AB


Also, from the attachment


Substitute 8.5 for y


--------- (1)
Also, from the attachment

Substitute 8.5 for z


----------- (2)
Subtract (2) from (1)


Make x the subject

Apply Pythagoras Theorem:
We have that:

The above can be replaced with
(see attachment)

Substitute 6 + w for x




Reorder

Solve using quadratic equation:

Where







Split:
or 
or 
or 
But length can't be negative
So:

Recall that: 


<em>Hence, the length of the legs is 8.64cm and 14.64cm respectively</em>
<h2>
Answer:</h2>
Total decease will be 0.75 cm
<h2>
Step-by-step explanation:</h2>
Decrease in height in each year = 1/4 cm

0.75
Answer:
b < 5
Step-by-step explanation:
-2+b<3
Add 2 to each side
-2+2+b<3+2
b < 5
The answer is D. B has the number 3 has the first numbers so that’s not it. C has the number 4 has the first numbers so thats not it. D is the only one that have different numbers in first numbers in the order (5, 8, 9)
