Answer:

Hence, the Female and not participated is \frac{28}{100}=0.28\%

Step-by-step explanation:

Let Total respondents =100

Participated in online action (P)=65

Men (m)=45  and Women (F)=100-45=55

Male and participated (M\; \text{and}\;P)=38

Female and participated (F\; \text{and}\;P)=65-38=27

Male and not participated is 45-38=7

Female and not participated is 55-27=28

Therefore, the Female and not participated is \frac{28}{100}=0.28\%

Hence, the correct option is D.

Keisha wants to meet for 90 minutes so far she has read 30% of her goal how much longer does she need to read to reach her goal
sladkih [1.3K]

Answer:

30% of 90             

30% x 90              

30/100 =3/10              

3/10 x 90 = 270/10          

270 = 27     

90 - 27 = 63          

Keisha has to read 63 more minutes to reach her goal.

If a globe rotates 150 degrees in 5 seconds, how many rotations does it make in 30 seconds? I got 900 seconds for my answer am I
Maksim231197 [3]

Start with a proportion, to get the number of degrees in 30 seconds:

         (150 degrees / 5 seconds) = ('D' degrees / 30 seconds) .

Cross multiply the proportion:  (150 x 30) = 5 x D

                                                     4,500  =  5 x D

Divide each side by  5 :                  900 = D

The globe turns 900 degrees in 30 seconds.

How many rotations is that ?
Each rotation is 360 degrees.
So 900 degrees is
                               (900 / 360) = <em>2.5 rotations</em> in 30 seconds.
