Answer 2

Answer:

Answer:

$31.80

Step-by-step explanation:

first convert 6% into a decimal which is 0.06. then multiply 30 by 0.06 to get 6% of 30 which is 1.80. then add 1.80 to 30 to get your final cost of 31.80

$30*0.06=1.80$

$30+1.80=31.80$

final cost: $31.80

Hope this helps!

Answers

The given distance driven by each family on vacation is-

The Jacksons drove 835 miles.

The Simms drove 947 miles.

The Chens drove 100 miles further than the Jacksons that is they drove 935 miles.

Now comparing all three distances, we get 947 miles as the highest distance driven.

Hence the Simms drove the longest distance.

The base diameter and the height of a cone are both equal toX units.
Which expression represents the volume of the cone, in
cubic units?
Piex2
2piex3
o 1/3piex?
o 1/12piex

Answers

Answer:

For this case we know that the diameter and height of a cone are both equal. That means:

$h = D=x$

With $D =2r$ with r the radius. The volume of a cone is given by:

$V =(1)/(3) \pi r^2 h$

And for this case we know that h =x and $x =2r$ so then $r= (x)/(2)$

And replacing we got:

$V= (1)/(3) ((x)/(2))^2 (x)= (1)/(12) x^3$

And the best option would be:

1/12pix^3

a group of students is donating blood during a blood drive. a student has 9/20 probability of having type 'o' blood and a 2/5 probability of having type 'A'.what is the probability that a student has type 'o' or type 'a' blood and why?

Answers

For the answer to the question above,
the answer is "The student can have only one blood type, so the actual events are mutually exclusive. "

The probabilities are not mutually exclusive. Based on the group

P(Type O) = 9/20 = 45% or 0.45
P(Type A) = 2/5 = 40% or 0.40
P(Other) = 3/20 = 15% or 0.15
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
