Multiple by moving the decimal point 24.6x100,37x1,000 0.367x10,000,0.005x1000,000 .

lesya [120]

The answers are 2460, 37,000, 3670 and 5000

Step-by-step explanation:

Step 1: Find the answers for each by multiplying.

24.6 × 100 = 2460 (moved one decimal point)

37 × 1000 = 37,000

0.367 × 10000 = 3670 (moved three decimal points)

0.005 × 1000,000 = 5000 (moved three decimal points)

from the top of a 120-foot high tower an air traffic controller observes an airplane on the runway at an angle of depression of

Crazy boy [7]

Data:
h (Tower height) = 120 ft
d (Distance from the base of the tower to the airplane) = ?
 $\alpha$ (Angle formed from observation of the tower to the airplane)=19º

Data: tg 19º ≈ 0.34

Note: The angle formed is tangent to the height of the tower and the distance from the base of the tower to the airplane.

Formula:
 $tg \alpha = \frac{opposite\:leg}{adjacent\:leg}$

Solving:
 $tg \alpha = \frac{opposite\:leg}{adjacent\:leg}$
$tg 19^0 = \frac{h}{d}$
$tg 19^0 = \frac{120}{d}$
$0.34 = \frac{120}{d}$
$0.34*d = 120$
$0.34d = 120$
$d = \frac{120}{0.34}$
$\boxed{\boed{d \approx 352.9\:ft}}\end{array}}\qquad\quad\checkmark$

Answer:
Distance from the base of the tower to the airplane is aproximately 352.9 ft

X+4y=11 and 2x+2y=-8 solve by elimination

Sliva [168]

Multiply the first equation by -2,and multiply the second equation by 1.−2(x+4y=11)1(2x+2y=−8)Becomes:−2x−8y=−222x+2y=−8Add these equations to eliminate x:−6y=−30Then solve−6y=−30for y:−6y−6=−30−6(Divide both sides by -6)y=5Now that we've found y let's plug it back in to solve for x.Write down an original equation:x+4y=11Substitute5foryinx+4y=11:x+(4)(5)=11x+20=11(Simplify both sides of the equation)x+20+−20=11+−20(Add -20 to both sides)x=−9Answer:x=−9 and y=5
