The volume of the given square pyramid in cubic feet is 2.5 cubic feet.

Given that, a square pyramid has a volume of 4320 cubic inches.

We need to find the volume of this pyramid in cubic feet.

The volume of a square pyramid is one-third of the product of the area of the base and the height of the pyramid. Thus, volume = (1/3) × (Base Area) × (Height).

To convert from cubic inches to cubic feet, divide your cubic inches figure by 1728.

Now,  4320/1728 = 2.5 cubic feet

Therefore, the volume of the given square pyramid in cubic feet is 2.5 cubic feet.

The equivalent expression using laws of exponents gives us; 2 over quantity 9 times d raised to the negative fourteenth power end quantity

We want to write an equivalent expression for 4 times d raised to the negative fifth power all over quantity 18 times d raised to the ninth power end quantity. This can be expressed as;

4d⁻⁵/18d⁹

Now, according to laws of exponents, we know that;

x²/x³ = x²⁻³ = x⁻¹

Applying that law to our question gives us;

4d⁻⁵/18d⁹ = (4/18)(d⁻⁵⁻⁹)

= (4/18)(d⁻¹⁴)

Now, the expression 4/18 can be broken down to 2/9. Thus, our final expression is; ²/₉d⁻¹⁴

The fractional error for given example is 0.0057

For given question,

the theoretical value of a quantity is 3.142,

and the calculated value is 3.16

We know that, the fractional error is the ratio of the absolute difference and the accepted value.

Fractional error =  absolute difference / accepted value

Fractional error = |E - A| / A

Here, A = 3.142

E = 3.16

So, the absolute difference would be,

|E - A| = |3.16 - 3.142|

          = 0.018

Now we find the fractional error.

⇒ Fractional error = |E - A| / A

⇒ Fractional error = 0.018 / 3.142

⇒ Fractional error = 0.0057

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are:

Initial = $200

Rate = $30

Let the number of months be n

So, we have

f(n) = Initial + Rate * n

This gives

f(n) = 200 + 30n

There are 12 months in a year

So, we have:

f(12) = 200 + 30 * 12

Evaluate

f(12) = 560

We get the translation rule as (x-4, y+5) for triangle ABC.

We are given a triangle:

ABC where

A = (3, -1)

B = (7, -5)

C = (-2, -2)

And, we are also given the translation of the triangle as A'B'C'

where

A' = (-1, 4)

B' = (3, 0)

C' = (-6, 3)

We need to tell the translation rule for it,

For the x coordinate, we can see that:

- 1 - 3 = - 4

3 - 7 = - 4

- 6 - (-2) = -4

So, the rule for x coordinate will be:

x - 4

Now for y coordinate:

4 - (-1) = 5

0 - (-5) = 5

3 - (-2) = 5

So, the rule for y coordinate will be:

y + 5

Translation rule then becomes:

(x-4, y+5)

Therefore, we get the translation rule as (x-4, y+5) for triangle ABC.

Answer:

Step-by-step explanation:

from the sign it's a right angle, so 90°

90 = x - 8 + 6x

90 + 8 = 7x

98 = 7x

x = 98 : 7

x = 14

------------------

[tex]\begin{aligned}\textsf{b)} \quad m \angle 1 & =\boxed{6^{\circ}}\\ m \angle 2 & =\boxed{84^{\circ}}\end{aligned}[/tex]

Step-by-step explanation:

From inspection of the given diagram, the sum of the two angles is 90° (indicated by the right angle sign):

[tex]\implies m \angle 1+m \angle 2=90^{\circ}[/tex]

[tex]\implies (x - 8)^{\circ} + (6x)^{\circ} = 90^{\circ}[/tex]

[tex]\implies x-8+6x=90[/tex]

[tex]\textsf{Equation}: \quad \boxed{x-8+6x=90}[/tex]

To find the measure of each angle, solve the equation for x:

[tex]\implies x-8+6x=90[/tex]

[tex]\implies x+6x-8=90[/tex]

[tex]\implies 7x-8=90[/tex]

[tex]\implies 7x-8+8=90+8[/tex]

[tex]\implies 7x=98[/tex]

[tex]\implies \dfrac{7x}{7}=\dfrac{98}{7}[/tex]

[tex]\implies x=14[/tex]

Substitute the found value of x into the expression for each angle:

[tex]\implies m \angle 1=(x-8)^{\circ}[/tex]

Answer: The length of AB =4 units

               The length of BD = 2.4 units.

Step-by-step explanation:

Given data,

                  AD = 3.2 unit

                  BC  = 3 unit

                 CD  = 1.8 units

Find :         AB =? units

                  BD=? units

We can use the formula of Pythagorean theorem,

Define Pythagorean theorem :

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.

Hypotenuse2 = Perpendicular2 + Base2

                  c2 = a2 + b2

Where “a” is the perpendicular,

“b” is the base,

“c” is the hypotenuse.

Let be a ΔABC,

                           [tex](AB)^{2} = (BC)^{2} +(AC)^{2}[/tex]

From the above formula now  determined  the value of AB and BD,

Firstly , find the value of BD

In ΔBDC, by applying Pythagorean theorem,

                             [tex](BC)^{2} = (BD)^{2} + (DC)^{2}[/tex]             (Eq - 1)

Substitute BC and CD values in equation 1,

            BC  = 3 units and CD = 1.8 units

So,

We can write,

                            [tex]3^{2} = (BD)^{2} +(1.8)^{2}[/tex]

                            9 = [tex](BD)^{2}[/tex] + 3.24

                            [tex](BD)^{2}[/tex] = 9 - 3.24

                            [tex](BD)^{2}[/tex] = 5.76

                             [tex]BD = \sqrt{5.76}[/tex]

                             BD = 2.4 units             (Eq - 2)

Now find the value of AB,

In ΔABD, by applying Pythagorean theorem,

                               [tex](AB)^{2} = (AD)^{2} +(BD)^{2}[/tex]           (Eq - 3)

Substitute AD and BD values in equation 3,

            AD  = 3.2 units and BD = 3 units

So,

We can write,

                                [tex](AB)^{2} = (3.2)^{2} + 3^{2}[/tex]

                                 [tex](AB)^{2}[/tex] = 10.24 + 5.76

                                 [tex](AB)^{2}[/tex] = 16

                                  AB = [tex]\sqrt{16}[/tex]

                                   AB = 4 units

Therefore,

The length of AB =4 units

The length of BD = 2.4 units.

Answer:

Y= (-27)

Step-by-step explanation:

Well, I am assuming your just looking for Y. So what I did was you'd want to get rid of the fraction first. I multiplied 3 to all the numbers. so -12(3) = 6(3) + 2y since the bottom 3 from the fraction cancelled out with the (3). so now it would be -36=18+2y. -54/2=2y/2 which leads to -27. So I think Y= -27.
