Answer:

79%

Step-by-step explanation:

He has 100% to start off. If he puts 21% into savings you subtract that from the starting amount. 100 - 21 = 79. Therefore the answer is 79%.

a plane is flying at a speed of 200 miles per hour. the pilot plans on flying at this speed for the next 225 miles, plus or minu
harina [27]

The minimum and maximum number of hours the plane will travel at that speed are; at least 0.875 hours and at most 1.375 hours

<h3>How to Solve Absolute Value Inequality?</h3>

We are given that the speed of the plane is 200 miles per hour.

Now, formula for time taken is;

Time = Distance/Speed

If the speed is 225 ± 50 miles, then it means that;

Maximum distance = 275 miles

Minimum distance = 175 miles

Thus, we can say that;

Minimum number of hours = 275/200 = 1.375 hours

Maximum number of hours = 175/200 = 0.875 hours

Find the positive value of x in the geometric sequence 7x-2,4x+4,3x
Goryan [66]
Hello,


Let's assume k the ratio.

&#10; \left \{ {{3x=k*(4x+4)} \atop {4x+4=k*(7x-2)}} \right. \\\\&#10; \left \{ {{3x-4kx=4k} \atop {4x-7kx=-2k-4}} \right. \\\\&#10; \left \{ {{x(3-4k)=4k} \atop {x(4-7k)=-2k-4}} \right. \\\\&#10; \left \{ {{x=\dfrac{4k}{3-4k} \atop {x=\dfrac{-2k-4}{4-7k} \right. \\\\&#10;&#10;\dfrac{4k}{3-4k}=\dfrac{-2k-4}{4-7k}\\\\&#10;&#10;36k^2-6k-12=0\\&#10;6k^2-k-2=0\\&#10;&#10;\boxed{k= \dfrac{2}{3} \ or\ k= -\dfrac{1}{2}}\\\\&#10;&#10;x=\dfrac{4*\dfrac{2}{3} }{3-4*\dfrac{2}{3} }=8\\&#10;x=\dfrac{4*\dfrac{-1}{2} }{3-4*\dfrac{-1}{2} }=-\dfrac{2}{5}\\&#10;&#10;&#10;&#10;&#10;&#10;

\boxed{x= 8 \ or\ x= -\dfrac{2}{5}}\\\\
