Answer:

A cross section parallel to the base is a square measuring 4 cm by 4 cm.

A cross section perpendicular to the base through the midpoints of opposite sides is a square measuring 4 cm by 4 cm.

A cross section that passes through the entire bottom front edge and the entire top back edge is a rectangle measuring 4 cm by greater than 4 cm.

Step-by-step explanation:

Cross sections parallel and Perpendicular to the base are squares 4 × 4

The diagonal cross section will be a rectangle with base 4 and height

sqrt(4² + 4²) = 4sqrt(2) > 4

Given: AABC, m_ACB=90°,<br> CD 1 AB, m ZACD=60º,<br> BC = 6 cm<br> Find: CD, Area of AABC

just olya [345]

Answer:

Look below

Step-by-step explanation:

Given that CDB is 90 degrees, ACB is 90 degrees, and ACD is 60 degrees, we can determine that DCB = 90-60 = 30 degrees.

This means triangle BCD is a 30-60-90 (angle measures) right triangle

The proportions of the sides (from smallest to largest) is

x:x√3:2x

We are given that BC = 6 cm. This means...

2x=6

x=3

This means DB is 3 cm and CD is 3√3 cm

Using the linear pair theorem, we can find that Angle CDA is 90 degrees. This means ACD is also a 30-60-90 triangle.

x=3√3

x√3=9

2x=6√3

Now we need to find AB

AB = AD + DB

AB = 9 + 3

AB = 12 cm

$Area = \frac{1}{2} bh = \frac{1}{2}(12)(3\sqrt3)=6(3\sqrt3)=18\sqrt3$

What is five x plus negative three equals fifteen

bearhunter [10]

You write the equation like this:
$5x + (-3) = 15$

But if you want to solve it then you do it like this:
$5x + (-3) = 15$
$5x - 3 = 15$
$5x = 18$
$x = 18/5$

Replace * with a number in such a way that the trinomial could be written in the form a(x+b)^2 or a(x-b)^2.

weqwewe [10]

Answer:

a) 6
b) 3.125 or 25/8

Step-by-step explanation:

1.5x² + 6x + * =
1.5(x² + 4x + *) =
1.5(x² + 2*2x + 4) =
1.5(x + 2)²
* = 1.5*2² = 6

2x² - 5x + * =
2(x² - 2.5x + *) =
2(x² - 2*1.25x + 1.25²)=
2(x - 1.25)²
* = 2*(1.25)² = 3.125 or 25/8

Find the 72nd term of the arithmetic sequence 11, 7, 3, ...

Katen [24]

Answer:

-273

Step-by-step explanation:

find the common difference:

d = 7 - 11 = - 4

a_1 = 11

a_72 = (72 - 1)* (-4) + a_1

a_72 = (71)* (-4) + 11

a_72 = -273
