. Find the quotient of 31,017 ÷ 49 and then show how you would estimate the problem.

1 answer:

8 0

The quotient of 31017 divided by 49 would be 633. The estimation of 31,017 would be 31,000 and 49 would be 50. The answer to that would be 620

Answer:

1. a=85.8 c=89.2

2. x=29.7 8x=2937. 3

Step-by-step explanation:

2. 8x+x+27°+66°=360°

8x+x=360°-66°-27°

9x=267 >Then divide both sides with 9

x=29,666666...

=8X

=8 (29,66666...)

=237,333...

1. 6X+4X+32°=180°

10X=180°-32

10X=148° >divide both sides with 10

X=14.8

A=6x c=4x+32

=6(14.8) =4(14.8)+32

= 88.8 =91.2

When an object is droppednbsp on a certain earth dash like planet comma on a certain earth-like planet, the distance it falls in

ANTONII [103]

Answer:

(a) $s(44) = 3.52*10^{6}ft$

(b) $v(44) = 10*x^{5} ft/s$

Step-by-step explanation:

$s(t) = 1818t^{2}$

(a) when t = 44sec

$s(44) = 1818(44^{2}) = 1818(1936)\\ \\s(44) = 3519648ft$

s(44) ≅ $3520000=3.52*10^{6}ft$

(b) How fast the hammer is traveling i.e. the speed of the hammer.

To find speed, we differentiate the distance s(t) with respect to time, t

$speed,v=\frac{ds(t)}{dt}=\frac{d}{dt}(1818t^{2}) \\\\v = 1818*2t^{2-1}= 1818*2t\\ \\v = 3636t$

at t = 44sec,

$v = 3636*44=159984ft/s$

$v$ ≅ $160000ft/s = 1.6*10^{5}ft/s$

(c) The hammer's acceleration can be obtained by differentiating the speed v(t) with respect to time, t

$acceleration, a = \frac{dv}{dt}=\frac{d}{dt}(3636t)\\ \\a = 3636*1= 3636\\\\a = 3636ft/s^{2}$

There's no need to substitute t = 44sec because the acceleration is independent of time.

What amount of a 70% acid solution must be mixed with a 30% solution to produce 600 mL of a 55% solution?

Kipish [7]

(%)(V1)+(%)(V2-V1)=(%)(V2)
(0.70)(x)+(0.30)(600mL-x)=(0.55)(600)
(0.70x)+(180)-(0.30x)=330
(0.70-0.30)x=330-180
(0.40)x=150
x=(150)/(0.40)
x=375 mL

Does the graph represent a function?

Pavlova-9 [17]

The graph represents a function.
You can tell if a graph is function or not by using the vertical line test.
If the line only passes one point of the y-axe, it is a function. But when the graph passes more than two points, it is not a function.
