Q1: The answer is A. pyramid.
A pyramid has one polygon base. A prism has two polygon bases. A cone has one circular base. A cylinder has two circular bases.

Q6: The answer is false.
Surface area of a rectangular prism is:
A = 2(wl + hl + hw)
A1 = 2(4*5 + 6*5 + 6*4) = 2(20+30+24) = 2*74 = 148
A2 = 2(6*4 + 5*4 + 5*6) = 2(24+20+30) = 2*74 = 148

Q7. The answer is A. 6 feet
The volume of rectangular prism is:
V = w * l * h
w = ?
So, just replace the knowing facts:
288 = w * 8 * 6
288 = w * 48
w = 288/48 = 6

Q8: The answer is 216 ft³
The volume of the cube is:
V = a³
Since a = 6, then:
V = 6³ = 216

Using the distance formula, d = √(x2 - x1)2 + (y2 - y1)2, what is the distance between point (-10, 12) and point (5, 3) rounded

Whitepunk [10]

Answer:

<h3>The answer is 17.5 units</h3>

Step-by-step explanation:

Using the distance formula

<h3> $d = \sqrt{ ({x2 - x1})^{2} + ({y2 - y1})^{2} }$ </h3>

the distance between (-10, 12) and (5, 3) is

<h3> $d = \sqrt{ ({5 + 10})^{2} + ({3 - 12})^{2} }$ </h3><h3> $d = \sqrt{ {15}^{2} + ( { - 9})^{2} }$ </h3><h3> $d = \sqrt{225 + 81}$ </h3><h3> $d = \sqrt{306}$ </h3><h3> $d = 3 \sqrt{34}$ </h3>

d = 17.492855

We have the final answer as

<h3>d = 17.5 units to the nearest tenth</h3>

Hope this helps you

Work out the area of a rectangle with base, b = 32mm and perimeter, P = 82mm.

Amanda [17]

Perimeter = 2base + 2base
82 - 2(32) = 18 : 2 = 9
area = 9*32 = 288mm^2
