Answer:
T = 94.59 degree C
Step-by-step explanation:
Given data:
P= 83.4 kPa
P = 0.834 bar
for Saturated table
P = 0.8 bar T = 93.50 degree C
P = 0.9 bar T = 96.71 degree C
from interpolation method
z = 1.0914
T = 93.5 + z = 94.59 degree C
Answer:
B. 7854.0 cm2
The area of a circle is given by A= π 
where r is the radius
So A= π
= 7854.0 cm2
2nd angle measures 50
90 is the total so all that was needed is to subtract 40 from 90
Answer:
y = 18
a = -2
Step-by-step explanation:
Hello There!
For the first one we need to create an equation to solve for y
23+7=y+12
30=y+12
isolate the variable using inverse operations
subtract 12 from each side
30-12=18
we're left with y = 18
for the second one we need to create an equation to solve for a
3+15+a=8+8+8
3+15=18
8+8+8=16
16=18+a
step 1 subtract each side by 18
16-18=-2
we're left with a = -2
