What is the percent of 110 to 275
Ksenya-84 [330]
275 = 100%
110 = x%

Cross Multiply

275 * x = 100 * 110
275x = 11000
x = <u>11000</u>
        275
x = 40

110 = 40%

Solution: 40%

The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,
 
                                         an = a1 + (n - 1) d

Solving for the 23rd term, 
 
                                          an  = 4 + (22) 5 = 114 seats

Therefore, the answer is there are 114 seats on the 23rd row.

Find the missing side of this right triangle
borishaifa [10]

Answer:

x ≈ 14.7

Step-by-step explanation:

use pythagorean therorem

a^2 + b^2 = c^2

c is hypotenuse and we know the hypotenuse is 21

a^2 + b^2 = c^2

x^2 + 15^2 = 21^2

x^2 + 225 = 441

x^2 = 216

x = √216

x ≈ 14.7

After sitting on a shelf for a while, a can of soda at room temperature (73 F) is placed inside a refrigerator and slowly cools.
Alona [7]

Answer:

Step-by-step explanation:

Use Newton's Law of Cooling here:

T(t)=T_s+(T_0-T_s)^{-kt

where T(t) is the temp of something after a certain amount of time, t, has gone by; Ts is the surrounding temp, and T0 is the initial temp. k is the constant of cooling. We need to first solve for this using the information given. Filling in what we know:

53=35+(73-35)^{-35k which can simplify a bit to

53=35+(38)^{-35k and 18=38^{-35k

Take the natural log of both sides:

ln(18)=ln(38)^{-35k

Taking the natural log allows us to pull that exponent down out front:

ln(18)=-35k*ln(38)

and now we can divide both sides by ln(38) to get

-35k = .794585 so

k = -.023

Now that have the value for k, we can go on to solve the rest of the problem which is asking us the temp of the soda after 70 minutes. Filling in using the k value and the new time of 70 minutes:

T(t)=35+(38)^{70(-.023) and

T(t)=35+(38)^{-1.61 and

T(t)=35+.0028612013 and

T(t) = 35 F, basically the temp of the fridge, which is not surprising!
