Answer:

Option D is correct

-3m -4n +14

Step-by-step explanation:

Given:

Q = 7m + 3n,

R = 11 - 2m,

S = n + 5, and

T = -m - 3n + 8.

We have to Simplify R-S+T

R -S +T = 11 - 2m - (n+5) + (-m -3n +8) = 11 - 2m-n-5-m-3n+8

Combine Like terms we have;

R -S +T = -3m -4n +14

Therefore, the Simplification of R -S +T is, -3m -4n +14

A fireman's water hose shoots 320 kg of water each second against the door of a building. The velocity of the water is 20 m/s an

NeX [460]

Answer:

$6400\ \text{N}$

Step-by-step explanation:

$\dfrac{m}{t}$ = Mass flow rate of water = 320 kg/s

$m$ = Mass of water on the door

$t$ = Time

$v$ = Velocity of water on the door = 20 m/s

Force is given by

$F=\dfrac{m}{t}v\\\Rightarrow F=320\times 20\\\Rightarrow F=6400\ \text{N}$

The average force is exerted by the stream of water is $6400\ \text{N}$ .

Solve the compound inequality 6b < 36 or 2b + 12 > 6.

Ne4ueva [31]

The solution to the compound inequality given as 6b < 36 or 2b + 12 > 6 is b < 6 or b > -3

<h3>How to solve the compound inequality?</h3>

The compound inequality is given as:

6b < 36 or 2b + 12 > 6

Evaluate the like terms in the individual inequalities

6b < 36 or 2b > -6

Divide the individual inequalities by the coefficients of b

b < 6 or b > -3

Hence, the solution to the compound inequality given as 6b < 36 or 2b + 12 > 6 is b < 6 or b > -3

A floor lamp originally cost $44.50. Over a period of two months, it underwent the following changes in price. 62% Markup 15% Ma

Luba_88 [7]

We have to find the final price of the floor lamp after all changes in price.
If the price changes 62% Markup we will multiply previous price by 1.62
( 100% + 62% = 162% = 1.62 ). Also for 15% Markdown we will multiply it by 0.85 ( 100% - 15% = 85% = 0.85 ) and so on:
$44.50 * 1.62 * 0.85 * 1.18 * 1.20 * 0.55 = $47.72
Answer:
B. $47.72
