Answer:
the first oe
Step-by-step explanation:
How many tens are in 212?
Lets break it up.
200 has 20 tens
and 12 has 1 ten.
20 + 1 = 21
Answer: 21 tens.
Answer:
y = 9.8x + 6.7
y = 6.7x + 9.8
y = 7.5x + 3.8
y = 3.8x + 7.5
Step-by-step explanation:
I made 2represent x.
y= 9.8(2) + 6.7
y = 26.3
y=6.7(2) + 9.8
y= 23.2
y= 7.5(2) + 3.8
y= 18.8
y= 3.8(2) + 7.5
y= 15.1
The volume of the aquarium is V= Lx wx H
it is already given that V=11.25 cubic feet, so <span>11.25=LxWxH
H height and it is the aquarium's depth
H=11.25 / L xW= 11.25/2.5x1.5= 3 feet</span>
We need to convert 135.28º in degree, minute, and second measure.
In order to do so, notice that:
![135.28\degree=135\degree+0.28\degree](https://tex.z-dn.net/?f=135.28%5Cdegree%3D135%5Cdegree%2B0.28%5Cdegree)
Also,
![1\degree=60^{\prime}](https://tex.z-dn.net/?f=1%5Cdegree%3D60%5E%7B%5Cprime%7D)
Thus, we have the proportion:
<em>degrees minutes</em>
<em> 1 60</em>
<em> 0.28 x</em>
Then:
![x=0.28\cdot60=16.8](https://tex.z-dn.net/?f=x%3D0.28%5Ccdot60%3D16.8)
Thus:
![0.28\degree=16.8^{\prime}=16^{\prime}+0.8^{\prime}](https://tex.z-dn.net/?f=0.28%5Cdegree%3D16.8%5E%7B%5Cprime%7D%3D16%5E%7B%5Cprime%7D%2B0.8%5E%7B%5Cprime%7D)
Now, notice that:
![1^{\prime}=60^{\doubleprime}](https://tex.z-dn.net/?f=1%5E%7B%5Cprime%7D%3D60%5E%7B%5Cdoubleprime%7D)
Thus, we have the proportion:
<em>minutes seconds</em>
<em> 1 60</em>
<em> 0.8 y</em>
Then:
![y=0.8\cdot60=48](https://tex.z-dn.net/?f=y%3D0.8%5Ccdot60%3D48)
Therefore:
![135.28\degree=135\degree16^{\prime}48^{\doubleprime}^{}](https://tex.z-dn.net/?f=135.28%5Cdegree%3D135%5Cdegree16%5E%7B%5Cprime%7D48%5E%7B%5Cdoubleprime%7D%5E%7B%7D)
And the first option is correct.
