Is 7/8 or 11/10 closer to 1
Firlakuza [10]
10. Find which one of the given fractions are value closer to 1. First = 7/8 Second = 11/10 Let’s start solving Let us start with the first value which is 7/8 => 7 needs to be divided with 8 => 7 / 8 = 0.875 Now, let’s solve the second value which is 11/10 => same with first solution., divide 11 by 10 => 11 / 10 => 1.1 Thus, 11/10 is the has the nearest value to 1.

Sedaia [141]

Answer:

Airspeed in still air:  140 mph

Step-by-step explanation:

Let s represent the speed in still air.  Recognize that the distance traveled is the same in either direction.

Also note that SF is north of LA.

Distance to SF from LA     =      Distance to LA from SF

(s-20)(mph)(4 hr)                 =    (s+20)(mph)(3 hr)

Then:

4s - 80 = 3s + 60 => s = 60 + 80 + 140 (mph)

The airspeed of the plane was 140 mph in still air.  With a tail wind, the plane  is faster; with a headwind, slower.

The length of a rectangle is increasing at a rate of 9 cm/s and its width is increasing at a rate of 7 cm/s. When the length is
Hunter-Best [27]

Answer:

<em>129 </em>cm^2/s

Step-by-step explanation:

Increasing rate of length, \frac{dl}{dt}= 9 cm/s

Increasing rate of width, \frac{dw}{dt} = 7 cm/s

Length, l = 12 cm

Width, w = 5 cm

To find:

Rate of increase of area of rectangle at above given points.

Solution:

Formula for area of a rectangle is given as:

Area = Length \times Width

OR

A = l \times w

Differentiating w.r.to t:

\dfrac{d}{dt}A = \dfrac{d}{dt}(l \times w)\\\Rightarrow \dfrac{d}{dt}A = w \times \dfrac{d}{dt}l +l \times \dfrac{d}{dt}w

Putting the values:

\Rightarrow \dfrac{dA}{dt} = 5 \times 9 + 12 \times 7\\\Rightarrow \dfrac{dA}{dt} = 45 + 84\\\Rightarrow \bold{\dfrac{dA}{dt} = 129\ cm^2/sec}
