Answer:

-9

Step-by-step explanation:

We are summing the 3rd 4th and 5th terms because k goes from 3 to 5

The third term is

-2(3) +5 = -6+5 = -1

The fourth term is

-2(4) + 5 = -8+5 = -3

The fifth term is

-2(5) +5 = -10 +5 = -5

Add these 3 terms together

-1+-3+-5 = -9

PLZZZZ HELPPPPPP THIS IS TIMEDDDD!!!! *look at picture*
Kazeer [188]

Answer:

Height of the building = 50.8 ft

Step-by-step explanation:

A person and a building are casting the shadows at the same time of the day.

Triangles formed by the person and his shadow and the building and its shadow will be similar.

Therefore, corresponding sides of the similar triangles will be proportional.

\frac{x}{28}=\frac{5.8}{3.2}

x = \frac{5.8\times 28}{3.2}

x = 50.75

x ≈ 50.8 ft

how many liters of a 40% acid solution must be added to 12 liters of a 20% solution to obtain a 25% solution​
kkurt [141]

Answer:

The answer is 4 liters.

Step-by-step explanation:

We want a final 25% solution, which means that the solvent should constitute 25 percent of all the liters of solution.

Let us call x the litres of 40% solution, so when they are added to the 12 litres of 20% solution, the total litres of the new solution are:

x+12

of these liters, 25% must be the solvent:

N=0.25(x+12)

Now for the 40% solution, the liters of the solvent are 0.4x, and for the 20% liter solution, the liters of solve are 0.2*12=2.4 liters. Thus the total liters N of the solvent are

N=0.4x+2.4

Therefore

N=0.4x+2.4=0.25(x+12)

\therefore x=4\:litres

The lenght of a square's side would be between. What two numbers if its area is 220 cm2?​
My name is Ann [436]
<h3>Answer: between 14 cm and 15 cm</h3>

=======================================================

Explanation:

If the area is 220 \text{ cm}^2, then the side length is approximately \sqrt{220} \approx 14.83

The side lengths are between 14 and 15 cm.

-------

Or you could have your steps like this:

196 < 220 < 225\\\\\sqrt{196} < \sqrt{220} < \sqrt{225}\\\\\boldsymbol{14} < \sqrt{220} < \boldsymbol{15}\\\\
