Percent decreasebetween80 and 70

vagabundo [1.1K]

You basically do 80-70 as the numerator of a fraction which should equal 10 and then the denominater should be 80 so you then do 10 divided by 80 and multiply your answer by 100 Hope This Helps You

❤️ i need this last question

Answer: $10\left(\cos90^{\circ}+i\sin90^{\circ}\right)$

Step-by-step explanation:

Given

The complex number is $z_1=0+10i$

Complex number in polar form is given by

$z=r\left(\cos \theta +i\sin \theta\right)$

Compare it with the given complex number

$r=10$ and $\sin \theta=1$ which implies $\theta$ must be $90^{\circ}$

So, in the polar form, it is

$z_1=10\left(\cos90^{\circ}+i\sin90^{\circ}\right)\\z_1=10e^{i\frac{\pi}{2}}$

Tbe question doesn't state the number of days he walked to school out of 20 school days in the

Month of February.

Answer:

Kindly check explanation

Step-by-step explanation:

To. Obtain the fractional representayion for the number of days he walked to school ;

Let the number of days he walked to school = 10 (this is an hypothesized value)

Number of school days in February = 20

Fraction = 10 /20 = 0.5

The percentage of times walked to school : multiply the fraction obtained above by 100%
