Answer:
Can not be determined (CNBD)
Step-by-step explanation:
In the given triangle ACI,
M is the mid point of CI, So we have
CM= MI
also AM=AM ( reflexive property )
So far we have two pairs of corresponding sides are congruent in ΔCAM and ΔIAM
To prove that ΔCAM≅ΔIAM using SSS (side side side ) congruence theorem
we should have AC =AI , but it is not given,so we can not say that AC=AI
To prove that ΔCAM≅ΔIAM using SAS (side angle side ) congruence theorem
we should have ∠AMC=∠AMI, but it is not given,so we can not say that ∠AMC=∠AMI
We can not determine that ΔCAM is congruent to which triangle
Hence the answer is Can not be determined (CNBD)
Answer:
45 square meters
Step-by-step explanation:
we know that
The area of trapezoid is equal to
where
b1 and b2 are the parallel bases
h is the height of trapezoid (perpendicular distance between the parallel bases)
we have
substitute
Answer:
1.2218 atm
Step-by-step explanation:
From ideal gas formula,
PV=nRT
Where n= number of moles
V= volume
T= temperature=25.0°C
= (273 + 25) = 298 K
R= gas constant = 0.082 l atm /K mol.
Making P subject of formula we have
P= [nRT] /V
Then substitute the values we have
P= [0.5 x 0.082 x 298] / 10
P= 1.2218 atm
Answer:
6 ft/min
Step-by-step explanation:
Theres a neat trick to note; whenever you say per think of it as a fancy word for divide, because the label is always gonna be a/b (a per b)
Therefore,
the rate of feet per minute will be the feet divided by the minutes;
18 feet in 3 minutes = <u>18</u>/3 <u>ft</u>/min
Therefore the rate is 6 feet per minute.
<u>IF you need an explanation on what average rate implies:</u>
<em>Note; the word average is not prudent to answer as its extraneous, however if there was more data like "Cami descends 18 ft in 3 min and Nami descends 9 ft in 3 minutes; whats the average rate at which they descend" then you'd have to add the two rates up and divide by two.</em>
Hope this helps :)
