What does a star mean after a number

Triss [41]

A star is written to show multiplication. It is a replacement for a dot or a x which is what you probably learned to be the "times" sign. In upper level maths, the "x" is replaced with a " * " to make it more legible and to avoid confusion with the variable "x".

100 POINTS HELP ASAP NOW!!!!!!<br> Find the value of x in each case.

Zepler [3.9K]

Answer:

x = 22.5°

Step-by-step explanation:

The interior angle at E is (180 -4x), the supplement of the exterior angle there, 4x. The sum of angles 2x and (180-4x) will be equal to 6x, because alternate interior angles at transversal BE are congruent:

2x +(180 -4x) = 6x

180 = 8x . . . . . . . add 2x and simplify

22.5 = x . . . . . . . divide by 8

The value of x is 22.5°.

Suppose the height of the pyramid is 20 yards. What is the pyramid's volume?

DedPeter [7]

Answer : The correct option is, (B) 1500 cubic yards.

Step-by-step explanation :

Formula used to calculate the volume of square pyramid is:

$V=\frac{a^2\times h}{3}$

where,

V = volume of pyramid

a = base edge of pyramid

h = height of pyramid

Given:

Base edge of pyramid = 15 yards

Height of pyramid = 20 yards

Now putting all the given values in the above formula, we get:

$V=\frac{a^2\times h}{3}$

$V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}$

$V=1500\text{ yards}^3$

Therefore, the volume of pyramid is 1500 cubic yards.

HELP 30 POINTS!!!!!

Tamiku [17]

by pythagorean formula, the last side is √(61)

by cos rule

cos A

$= \frac{ {6}^{2} + 61 - {5}^{2} }{2 \times 6 \times \sqrt{61} } \\ = \frac{72}{12 \sqrt{61} } \\ = \frac{6}{ \sqrt{61} }$

A = 39.81
