Answer:

Step-by-step explanation:

Tri. prism:

B = base = 1/2 a c

base = 1/2 * 6 * 6 = 18

volume = Bh

v = 18*4

v = 72

Rec. prism

volume = 4*6*6

v = 144

total volume = 144+72

vt = 212

top rec. = 2*3*5=30

bot rec. = 4*5*6=120

vt = 30 + 120

vt = 150

Decompose the rectangle along the diagonal and recompose the two pieces to make a different shape

zaharov [31]

Decompose the rectangle along the diagonal and recompose the two pieces to make a different shape, then five different ways are shown.

<h3>Further explanation </h3>

Area is the number of squares inside a two-dimensional shape.

Here are two important principles for finding area:

If two figures can be placed one on top of the other, then they have the same area so that they match up exactly.
We can decompose a figure (break a figure into pieces) and rearrange the pieces (move the pieces around) to find its area.

A rectangle has two diagonals. Each one is a line segment drawn between the opposite vertices (corners) of the rectangle. For rectangle, shapes can be decomposed and rearranged back to rectangles to find the area. When decomposing and rearranging shapes the area of the polygon does not change.

The rectangle is shown in the picture below. After decompose the rectangle along the diagonal, we can varied the pieces to make various different shape. Picture below also shown the five different ways pieces from the rectangle.

Answer:

option 4 = 25

Step-by-step explanation:

given= chord js and hL intersects at poimt p

to find = value of x

solution:according to the therom;

if the line extensions of the chordJS and HL INTERSECTS at point K then their lenghts satisfy

JK×KS=HK×KL

10×30=X×12

300=12x

300/12=x

25= x

a snowball is rolled down a giant hill. the radius of the snowball grows. every second the radius increases by 0.36 inches. four

Bad White [126]

Based on the fact that the radius of the snowball increases by 0.36 inches every second, the linear function can be found to be y = 0.36x + 1.66

<h3>How to find the linear function?</h3>

The linear function is the function that shows how to change in the rate of the independent variable would affect the rate of change in the dependent variable.

The linear function takes the form:

y = mx + b

y = dependent variable

m = slope or change in radius of snowball

x = seconds

b = y-intercept

Solving for the y-intercept gives:

3.1 = 0.36(4) + b

b = 3.1 - 1.44

= 1.66

The linear function is therefore:

y = 0.36x + 1.66

What triangle pairs can be mapped to each other using a single tranlation

shepuryov [24]

Answer: I think Figure 4 is the correct one

Step-by-step explanation:

It is not possible to map the triangle MNP and CDE together using just a single translation in Figure 3. With Figure 4, we can use a translation to map the triangle MNP and the triangle CDE. Accordingly, in the diagram, the triangle MNP and the triangle CDE can be translated to each other.
