Answer:
<u>The correct answer is A. 12 minutes.</u>
Step-by-step explanation:
Let's solve for y, when x = 12, as follows:
y = 175 - 15x
y = 175 - 15 * 12
y = 175 - 180
y = - 5
This result means that after 12 minutes the fish tank would be completely drained and if it's needed 5 additional gallons of water could also be drained. It's not necessary to continue making more calculation with the the other options given because this is the right answer.
<u>The correct answer is A. 12 minutes.</u>
She's 230 feet from the shore and she starts swimming towards shore at 2ft/s and covers 20 ft then Maxx starts out at 5ft/s at this point 10 seconds will have elapsed ( remember to add this on).They have now to cover 210 ft between them so the ratio will be5:2 making 210 divide by 7 = 30secs. So max will cover 150 ft and belle will cover 60 ft. So in summation for Belle to cover 60ft it would take her 30 secs plus the first 10 secs total 40 secs
1) area of a cicular pool
area of a circle=πr^2 d=2.5 then r=2.5/2
A=3.14 *(2.5/2)^2
A=4.906m^2 A=4.9m^2
2) arae of a coin
<span>(if i read it right d=15mm?)
</span>A=πr^2 d=15 then r=15/2
A=3.14*(15/2)^2 =176.6mm^2
Rest all are same problems u try to solve it
(6,3x0,15)/1,5 = 0,945/1,5 = 0,63
<span>I hope to have helped you ! :)</span>
Answer:
belongs to the line 
. Please see attachment below to know the graph of the line.
Step-by-step explanation:
From Analytical Geometry we know that a line is represented by this formula:
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- y-Intercept, dimensionless.
If we know that 
, 
and 
, then we clear slope and solve the resulting expression:
Then, we conclude that point belongs to the line , whose graph is presented below.
