Explain why subtracting a positive number is the same as adding its inverse.
Explanation:
To add a negative number, we are basically subtracting it because of this:
Example:
10 - 5 = 5
10 + (-5) = 5
The negative sign cancels out the positive which makes it into a subtraction problem instead.
A square pyramid has a volume of 4320 cubic inches. What is the volume of this pyramid in cubic feet?
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.
What is the volume of a square pyramid?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 students she's had in 7 years is 850.
How to calculate the value?It should be noted that we want to find the 7th term. This will be:
a + (n - 1)d
a = First term = 250
d = Difference = 100
n = Number = 7
Therefore, a + (n - 1)d

You start a savings account with $200 and save $30 each month. Let f(n) be the amount in the account before the nth month. How much money will you have invested at one year?
The money you will have invested at one year is $560
What are linear equations?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
How much money will you have invested at one year?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
Hence, the money you will have invested at one year is $560

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.

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 = 14Angle 1 = 6°Angle 2 = 84°Step-by-step explanation:
from the sign it's a right angle, so 90°
Find x90 = x - 8 + 6x
90 + 8 = 7x
98 = 7x
x = 98 : 7
x = 14
------------------
check
90 = 14 - 8 + 6 * 14 (remember pemdas)
90 = 14 - 8 + 84
90 = 90
the answer is good
Find angle 1
x - 8
14 - 8 =
6°
Find angle 2

the answer is good
Answer:
[tex]\textsf{a)} \quad \textsf{Equation}: \quad \boxed{x-8+6x=90}[/tex]
[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:
Part (a)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]
Part (b)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]
[tex]\implies m \angle 1=(14-8)^{\circ}[/tex]
[tex]\implies m \angle 1=\boxed{6^{\circ}}[/tex]
[tex]\implies m \angle 2=(6x)^{\circ}[/tex]
[tex]\implies m \angle 2=(6 \cdot 14)^{\circ}[/tex]

Find the lengths of ABC and BD explain pls
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.

How to use laws of exponents?
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
