Which lengths can be used, directly or indirectly, to calculate the volume of the hexagonal right pyramid? Select three options. XY and ST VU and TW XS and XW TX and WX VU and YZ

Answers

Answer:

XYand ST , VU and TW, TX and WX

Step-by-step explanation:

Volume of hexagonal right pyramid =[tex]\frac{1}{3}[/tex]×Area of base ×height

Area of base =[tex]\frac{1}{2}[/tex]×apothem ×perimeter

if we consider face TXY  ,here height =ST  and  length XY

(b) consider face TVW,  length VU and TW

(d) consider face TWX, length WX and TX  

Hence lengths in options (a),(b),(d) can be used to find the volume of hexagonal right pyramid .

Answers

Answer:

<ABC = 51°

Step-by-step explanation:

Given

<A = 2x -15°

<B = x - 5°

< C = 148°

Now

<A + <B = < C ( Exterior angle of a triangle is equal to the sum of two opposite interior angles)

2x -15° + x - 5° = 148°

3x - 20° = 148°

3x = 148° +20°

3x = 168°

x = 168° / 3

X = 56°

Now for Angle B

= 56° - 5°

= 51°

If one of the diagonals of a rectangle is 20cm and the difference between the length and the width is 4cm. What is the area of the triangle

Answers

Answer:

192cm²

Step-by-step explanation:

The diagonal of the rectangle is expressed using the formula:

d = √l²+w²

l is the length

w is the width

Given d = 20

20 = √l²+w²

400 = l²+w² .... 1

Since the difference between the length and the width is 4cm, then;

l - w = 4 ... 2

l = 4 + w

Substitute equation 2 into 1;

400 = (4+w)²+w²

400 = 16 +8w + w² +w²

400 = 16 + 8w + 2w²

2w²+8w - 384 = 0

w²+4w - 192 = 0

w = -4±√4²-4(-192)/2

w = -4±√16+768/2

w = -4±28/2

w = -4+28/2

w = 24/2

w = 12

Since l = w+4

l = 12+4

l = 16

Area of the rectangle = 16 * 12

Area of the rectangle = 192cm²

What is Substitution Method?

The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the second equation in this procedure, as the name implies.

When a variable (or set of letters) in an algebraic statement is substituted, its numerical value is used instead.

Given:

y=x-8..................(1)

y=2x-14.................(2)

Substitute the value of y from equation (1) to equation (2), we get

x-8 = 2x- 14

2x - x = -8 + 14

x = 6

and, y= x-8

y= 6-8

y= -2.

Hence, the value of x is 6 and y is -2.

Students planted 2(3x + 4y) amount of trees on Saturday and then 3(x + 8) amount of trees on Sunday. What is the total amount of trees that the students planted? *

Answers

Answer:

(9x + 8y + 24) trees

Step-by-step explanation:

The total amount of trees the students planted is calculated as:

Amount of trees planted on Saturday + Amount of trees planted on Sunday

= 2(3x + 4y) + 3(x + 8)

= 6x + 8y + 3x + 24

= 6x + 3x + 8y + 24

= 9x + 8y + 24

Hence, the total amount of trees the students planted was (9x + 8y + 24) trees

dy/dy^2

we can cancel out the variable “d” by simply dividing. after we do so, we are left with y/y^2. when dividing variables with exponents, you subtract the exponent from the denominator’s variable from the exponent in the numerators variable.

for example, since we have just “y” as the numerator, we can think of it as “y^1”
so, y^1/y^2
y^1-1=y^0
we are left with y^0 or 1, over y^1 or y. think of this as 1/y

Question Parameters:

Xi-ling has a net income that is 5% of her monthly salary of $2,315. Xi-ling would like to keep a net income of $50

Generally,  5% of her monthly salary   is mathematically given as

x=0.05*2315

x=115.75

Therefore, if she has a net income equal to 115.75

y=115.75-50

y=65.75

Answers

Answer:

An equation of the line in a slope intercept form has a slope of -6 and passes through the point (2, -4) is: [tex]\mathbf{y=-6x+8}[/tex]

Step-by-step explanation:

We need to  write an equation of the line in a slope intercept form has a slope of -6 and passes through the point (2, -4)

The equation in slope-intercept form is : [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

We need to find slope and y-intercept for our equation.

In the question, we are given slope m = -6

Now, we need to find y-intercept.

Using slope m = -6 and the point (2,-4) we can find y-intercept

[tex]y=mx+b\\-4=-6(2)+b\\-4=-12+b\\b=12-4\\b=8[/tex]

So, we get y-intercept : b = 8

Now, the equation of line having slope m = -6 and y-intercept : b = 8 in slope-intercept form will be:

[tex]y=mx+b\\y=-6x+8[/tex]

An equation of the line in a slope intercept form has a slope of -6 and passes through the point (2, -4) is: [tex]\mathbf{y=-6x+8}[/tex]
