HELP ASAP PLEASE.

ValentinkaMS [17]

Answer:

pls give brainlist

Step-by-step explanation:

a. $\frac{50 blocks (L)}{9 blocks(W)\\}$ 50 x 9 = 450. A=450

b. I can scale the unit rate of the area given above and largen the area of the map. Ex. $\frac{7}{3}$ = $\frac{21}{6}$ <---(scaled by 2)

Then we can enlarge it however we want so,

$\frac{21}{6}$ = $\frac{42}{12}$ <--(scaled by 2 once more)

If the statement above is true then we can scale times 4.

$\frac{7}{3}$ = $\frac{42}{12}\\$ <---(scaled by 4)

A= $\frac{42}{12\\}$

all i can give u at the moment , if u go on M a t h w a y it can help

(3) Two people are at an elevator. At the same time one person starts to walk away from the elevator at a rate of 2 ft/sec and t

Gekata [30.6K]

Answer:

The rate at which the distance between the two people is changing 15 seconds later is 7.28 ft/sec.

Step-by-step explanation:

Here, we note the following

Let the person walking way fom the elevator be X

Let the other person going up in the elevator be Y

Therefore after 15 seconds, their positions will be;

For X, 2 ft/sec × 15 s = 30 ft away from the elevator

For Y, 7 ft/sec × 15 s = 105 ft up in the elevator

At that instant, the distance between them is given as

d² = x² + y²

= 30² +105² = 11925 ft²

d = √11925 ft² = 109.202 ft

The rate of change of the distance between the two peopl, X and Y is given as

$\frac{dd^2}{dt} = \frac{dx^2}{dt} + \frac{dy^2}{dt}$

Therefore, $2d\frac{dd}{dt} = 2x\frac{dx}{dt} + 2y\frac{dy}{dt}$ or $d\frac{dd}{dt} = x\frac{dx}{dt} + y\frac{dy}{dt}$

Since $\frac{dx}{dt}$ is given as 2 ft/sec and $\frac{dy}{dt}$ = 7 ft/sec

Then $d\frac{dd}{dt} = 30 \times 2 + 105 \times 7 = 795\\$

$\frac{dd}{dt} = \frac{795}{109.202 } =7.28 ft/sec$
