What is the volume of the shape
what is the volume of the shape - 1

Answers

Answer 1
Answer: the answer to this question would be D or 1512.
to solve this question, you find the volume of each prism. 
to find volume, you do length times width times height.
the top prism would be 15 times 12 times 6 which would be 1080
the bottom prism would be 6 times 12 times 6 which would be 432.
you add the volumes of the two prism or 1080+432= 1512.

hope this helps! :)
Answer 2

Which steps would you use to plot the point (7, −6, −5) in a 3-dimensional coordinate system starting from the origin?a. move right 7, down 6, and up 5
b. move forward 7, left 6, and down 5
c. move forward 7, down 6, and left 5
d. move up 7, back 6, and down 5

Answers

Answer:

B. move forward 7, left 6, and down 5

Step-by-step explanation:

By the convention of 3D geometry, the coordinates of a point (x,y,z) represent how far the point is from the origin forward-backward , right/left , up-down respectively with prior one for the positive coordinate and latter for the negative coordinate.

so we need to move forward 7 for x=7 then to left 6 for y=-6 and then down 5 for z=-5.

7 times as much as the sum of 1/3 and 4/5

Answers

First of all, you add 1/3 and 4/5, so you get:
(1)/(3) + (4)/(5)

To add 2 fractions, they need to have the same denominator. Since 3 and 5 don't have a common factor, so you multiply 1/3 by 5, and 4/5 by 3, so you get:
(1*5)/(3*5) + (4*3)/(5*3)
(5)/(15) + (12)/(15)

Now, the two fractions got the same denominator, and you can add them by adding the numerators over the same denominator. (You don't add denominators in addition) so you get:
(5+12)/(15)
(17)/(15)

That's the sum of 1/3 + 4/5.

Now, they want the sum of the 2 fractions 7 times. So you multiply 17/15 by 7. And as you know, 7 = 7/1. So you get:
(17)/(15) * (7)/(1)

In multiplication no need to have the same denominator. You multiply nominators by nominators and denominators by denominators. So you get:
(17*7)/(15*1)
(119)/(15)

Since 119 and 15 don't have a common factor, so they can't be simplified.
So, the answer is 119/15. 

Hope this Helps! :D

What you have to do first is to add (1)/(3) and (4)/(5),

Further Explanation

Therefore we have:

= (1)/(3) + (4)/(5)

= ( (1)/(3) + (4)/(5) ) / 15 (15 is the smallest number that divide both denominator also known as LCD)

= (5 x 1) + (3 x 4) / 15

= 5 + 12 / 15

= (17)/(15)

Therefore, the sum of (1)/(3) + (4)/(5) is (17)/(15)

But since the question says you should determine the sum of the 2 fractions, therefore you should multiply (17)/(15) by 7. Therefore you should have:

(17)/(15) X 7 (7 can also be expressed as (7)/(1))

= (17)/(15) x (7)/(1) (notably, in multiplication there is no need for the fraction to have the same denominator. You can multiply both numbers at the top together (numerator) and do same with the denominator.

= (119)/(15)

= 7(14)/(15)

Therefore, 7 times as much as the sum of (1)/(3) and (4)/(5) is 7(14)/(15)
