Answer:

205°

T(t) = 65°+20°t

Step-by-step explanation:

Let the temperature be T and time be t

<u>The equation to determine the temperature T after t minutes is:</u>

  • T(t) = 65° + 20°t

<u>For t = 7 we get:</u>

  • T(7) = 65° + 20°*7 = 65° + 140° = 205°

A rectangular field is twice as long as it is wide. if the perimeter of the field is 450 yards. what are the fields dimensions?
Nat2105 [25]
Let width = x
let length = 2x
x + 2x = 450
3x = 450
x = 150
width = 150
length = 2x = 2 (150) = 300

Determine if the sequence is arithmetic write yes or no 5,9,14,20
makkiz [27]

Answer: No

Step-by-step explanation:

An arithmetic sequence is one where the same number is being added to the number before it. For example, 2, 4, 6, 8..., where 2 is being added to each number.

In this case, however, the number being added is not consistent with this pattern. Between 5 and 9, the difference is 4 and between 9 and 14, the difference is 5, and so forth. This pattern does not follow the rules of an arithemtic sequence.

How do I answer this Question? It’s phythagoras theorem!
zhuklara [117]

Answer:

C = 11.18       D= 20

Step-by-step explanation:

Let's start with C

Square root both areas of the squares

\sqrt{25} =5

\sqrt{100}=10

Then use the Pythagoras Theorem: a^{2} +b^{2} =c^{2}

10^{2} +5^{2} =125

\sqrt{125} =11.18033989 = C

Moving on to D

Square root both areas of the squares

\sqrt{841} =29

\sqrt{441} =21

29 is the hypotenuse, we are trying to find the other leg, so:

29^{2} -21^{2} =400

\sqrt{400} =20 = D

One inlet pipe can fill an empty pool in 6 hours, and a drain can empty the pool in 9 hours. how long will it take the pipe to f
Dovator [93]
Inlet pipe can fill the pool in 6 hours, means: every hour the pool is filled 1/6 
a drain can empty the pool in 9 hours, means: every hour the pool is drained 1/9
If the inlet and the drain are both left open, every hour the pool is filled 1/6-1/9=1/18
It will take 18 hours to fill up the pool.
