A right rectangular prism has a length of 10 in., a width of 12 in., and a height of 16 in. The dimensions of the prism are halv
valkas [14]
The surface area of a rectangular prism can be found by adding the area of all sides together. To start, we will have to find the dimensions for the new prism, which is 5 * 6 * 8.

Then, we will have to find the area for each side. One of the sides will have 8*6, another 8*5, and the last 5*6.
We will then have 48, 40, and 30. Multiply them all by 2 and add them all together.
You will receive the final answer of 236 square inches.

Which student solved the equation w/13.5 = 9.7 correctly?​
Nataliya [291]

Answer:

Kwan's work

Step-by-step explanation:

The given equation is:

\frac{w}{13.5}=9.7

We multiply both sides by 13.5 to obtain:

\frac{w}{13.5}\times 13.5=9.7\times 13.5

We simplify to get;

w=9.7\times 13.5

We multiply out the RHS to get:

w=130.95

PLEASE HELP ME ON 6-11 AND SHOW WORK PLEASE!!
pychu [463]

Answer:

6) 6\sqrt{2}

9) 40

10) \frac{5\sqrt{2} }{2}

11) 13

Step-by-step explanation:

6)A right triangle rule: if 2 legs are equal, the hypotenuse is the length of that leg*\sqrt{2}

9) Pythagorean Theorem

a^{2} +b^{2} =c^{2}

We know the hypotenuse (41) so we substitute that for c and 9 for b now we need to find a

\sqrt{41^{2}-9^{2}  } which gives us 40

10) same with #6 but we do the opposite. SInce we have the hypotenuse, we can divide that by \sqrt{2} because we know that if 2 legs are equal, the hypotenuse is multiplied by \sqrt{2}. Multiply the numerator and denominator by \sqrt{2} because we can't have a square root in the denominator.

11) like #9 we have the a and b but we need to find c

a=5 b=12 c=r

so \sqrt{5^{2}+12^{2}  } which gives us 13
