Step-by-step explanation:
The area of a triangle is 1/2×width×length. Volume of a triangular prism is 1/2×width×length×height.
Fill in and we get 1/2×10×length×4=140. length=(140×2)/(10×4)=280/40=7. So you're right.
Let the width be x ft
the length will be (x+14) ft
hypotenuse is 34 ft
given that our triangle is right triangle, using Pythagorean theorem?
c^2=a^2+b^2
substituting our values in the formula we get:
34^2=x^2+(x+14)^2
1,156=x^2+x^2+28x+196
simplifying this we get
0=2x^2+28x-960
solving the quadratic equation we get:
x=16 or x=-30
therefore the width is 16 ft and the length is 16+14=30
Answer:
A
Step-by-step explanation:
First you find the volume of the cube which is 512. Then you find the volume of the cone which is 133.97333333 and so on. Lastly you subtract 512 by 133.973333333 (and so on) which is 378.026667. Rounded the answer would be 378.0 which is answer A.
Plz mark brainliest!!! I spent lot of time on this.
When it reads "the quotient of 3 more than a number and 5" it is separated as follows:
"the quotient of [3 more than a number] and [5]"
Therefore Quantity 1 is 3 more than a number and Quantity 2 is 5.
You can replace "a number" with a variable (they want you to use n in this case):
3 more than n
Which is the same as saying: 3 + n
Hope this helps! :)
