1. The answer is 269.3 cm³.

The volume of a the rectangular prism (V) is the product of its length (l), width (w), and height (h):
V = l * w * h

According to the image:
l = 12.1 cm
w = 5.3 cm
h = 4.2 cm

Therefore,
V = 12.1 * 5.3 * 4.2 = 269.3 cm³


2. The answer is 1,756.3 yd³.

The volume of the triangular prism (V) is:
V = 1/4 * h √(a⁴ + 2(ab)² + 2(ac)² * b⁴  + 2(bc)² * c⁴)
where: h - height of the prism,
a, b, c - sides of the base

According to the image:
h = 24 yd
a = b = c = 13 yd

Therefore:
V = 1/4 * 24 * √(13⁴ + 2(13 * 13)² + 2(13 * 13)² * 13⁴  + 2(13 * 13)² * 13⁴)
V = 1756.3 yd³

One number is 6 more than a second number, the sum of the two numbers is 330. what are the numbers?
maksim [4K]

Let's have the first number, the larger number, be <em>x</em>.  We'll have the second, smaller number be <em>y</em>.

We know that x = y + 6, since x is 6 greater than y.

We also know that 330 = x + y.

Because x = y + 6, 330 = y + 6 + y, which simplifies to 330 = 2y + 6.

Now all we need to do is simplify the equation.  First, we subtract 6 from both sides:

330 - 6 = 324

2y + 6 - 6 = 2y.

So we have 324 = 2y.  Then we divide both sides by 2 to get:

162 = y

Plug in y = 162 into the equation x = y + 6 to get:

x = 162 + 6

x = 168

Let's check to make sure our answer is right.  168 is 6 more than 162.  162 + 168 equals 330.  So our two numbers are 168 and 162.

Given a right ?ABC, where AB = 4.5 cm, BC = 7.794 cm, and AC = 9 cm, sketch the triangle below, and find the measure m?C in degr
Ksju [112]

Answer:

The measure of angle C is 30\°

The draw in the attached figure

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

The sine of angle C is equal to divide the opposite side to angle C by the hypotenuse

sin(C)=\frac{AB}{AC}

substitute the values

sin(C)=\frac{4.5}{9}

C=arcsin(\frac{4.5}{9})=30\°
