Answer:
Step-by-step explanation:
∠A - Angle can also be named by the vertex holding the angle.
∠TAR
∠RAT
Since we are decreasing by 40%
The new value would be 100% - 40% = 60% of the value
New value = 60% of 800
= (60 / 100) * 800 = 480
Am giving you 480 as the answer.
To find the value of x, use Pythagorean theorem which is a to the power of two plus b to the power of two equals the hypotenuse which Is c to the power of two, which you'd value as x. Square root the entire thing and you'll be left with c.
Answer:

Step-by-step explanation:
We have been given that are two racks with 40 towels per rack. On Tuesday there were 30, on Wednesday 50 and on Thursday 25. We are asked to find the fraction on average that is in use for the three days.
First of all, we will find total number of towel by multiplying 40 by 2.


Now we will find average number of towels used on three days.




Now we need to calculate 35 is what part of 80 to find the fractional use of towels per day as:


Therefore,
on average is in use for the three days.
<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them
we know from above that u.v = 120
|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29
so we know:
theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>
