Kalia’s parents give her simple interest on any money she saves for college. Which equation and solution represents the total interest, T, earned when the principal amount is $100, the annual simple interest rate is 1%, and the number of years is 10?
T = 100 • (10 + 0.1); $1,010
T = 100 • (10 + 0.01); $1,001
T = 100 • 0.1 • 10; $100
T = 100 • 0.01 • 10; $10
The equation and solution representing the total interest, T, earned by Kalia when the principal amount is $100, the annual simple interest rate is 1%, and the number of years is 10, is D. T = 100 • 0.01 • 10; $10.
What is the simple interest?Simple interest is interest that does not compound.
Simple interest does not accumulate interest, unlike compound interest, which is added to the principal for subsequent interest.
Principal = $100
Simple interest rate = 1%
Period of savings = 10 years
The simple interest in dollars = T
T = 100 x 0.01 x 10
T = $10
Thus, Option D correctly represents the total interest earned by Kalia.

Order of operationsThe Order of Operations tells you that multiplication takes precedence over addition, and expressions inside parentheses are evaluated first.

The division that can match the model is that 6 ÷ 1/5 = 30.
What is division?Division is one of the four fundamental mathematical operations, along with addition, subtraction, and multiplication. It is defined as the splitting of a large group into smaller groups so that each group has an equal number of items. In mathematics, it is an operation used for equal grouping and equal sharing.
It is a process of repeated subtraction. It is the inverse operation of multiplication. It is defined as the formation of equal groups. When we divide numbers, we break them down into smaller numbers so that the multiplication of those smaller numbers equals the larger number taken.
In this case, the division will be:

The sum of four positive integers is 125. If you increase the first number by 4, decrease the second by 4, multiply the third by 4, and divide the fourth by 4, you produce four equal numbers. What is the smallest of the original numbers
Step-by-step explanation:
a + b + c + d = 125
a + 4 = b - 4 = 4c = d/4
a + 8 = b
a = b - 8
16c = d
b = 4c + 4
4a + 16 = d
b - 8 + 4c + 4 + c + 16c = 125
4c + 4 - 8 + 4c + 4 + c + 16c = 125
25c = 125
c = 5
d = 16c = 80
4a + 16 = d = 80
4a = 64
a = 16
b = a + 8 = 16 + 8 = 24
so, the numbers are
16, 24, 5, 80
If f(x) = 4x² and g(x)=3x, what is (fg)(x)?
(fg)(x)=
(Simplify your answer.)
The multiplication of the given function is (fg)(x) = 12[tex]x^3[/tex]
What is operations of the function ?
Similar to how a function's constituent terms can be added, subtracted, multiplied, and divided, so can functions. These are to be noted as follows:
Addition f( x ) + g ( x ) means to combine two functions, and it may alternatively be expressed as ( f + g ) ( x )
It is possible to write ( f g ) ( x ) to represent the operation of subtracting the g(x) function from the f(x) function.
The two functions are multiplied together when you multiply f (x ) g (x), which can also be represented as (f g ) (x).
Division f (x)/g (x) means to split the two functions in half, and it can alternatively be expressed as (f/g)(x).
Here the given function ,
=> f(x) = 4[tex]x^2[/tex]
=> g(x)= 3x
Now (fg)(x) = f(x)*g(x)
=> (fg)(x)= 4[tex]x^2[/tex]*3x

Hence the (fg)(x) = 12[tex]x^3[/tex].

For isosceles triangle RST the measure of angle T is 34 degree
In this question, we have been given a isosceles triangle RST with RS = RT.
So, by isosceles triangle theorem,
angle S = angle T
So, angle T = (3x - 2)°
We know that the sum of all angles of triangle is 180°
∠R + ∠S + ∠T = 180°
9x + 4 + 3x - 2 + 3x - 2 = 180°
15x + 4 - 4 = 180°
15x = 180°
x = 12
So, 3x - 2 = 3(12) - 2
= 34°
Therefore, for triangle RST the measure of angle T is 34 degree

Find the dimensions of the rectangle with the largest area; it has two vertices on the x-axis and two vertices above the x-axis on the graph of
y = 5 − x^2.
Answer:
(2/3)√15 wide by 10/3 tall, approx 2.582 by 3.333
Step-by-step explanation:
You want the dimensions of the largest rectangle that fits under the graph of y = 5 -x² above the x-axis.
DimensionsThe graph of y=5-x² is symmetrical about the y-axis, so the width of it will be x -(-x) = 2x and the height will be 5-x².
AreaThe area will be the product of the width and height:
A = WH
A = (2x)(5 -x²) = 10x -2x³
Maximum areaThe area will be a maximum where the derivative of the area function is zero.
dA/dx = 10 -6x² = 0
x² = 10/6
x = (√15)/3
The corresponding rectangle dimensions are ...
width = 2x = (2/3)√15
height = 5 -x² = 5 -5/3 = 10/3
The rectangle with largest area is (2/3)√15 wide by 10/3 tall.

If a cone has a volume of 100 cubic inches, what is the length of the radius? Round your answer to the nearest tenth.
The radius of the cone is 10√(3/πh) inches when the volume of the cone is 100 cubic inches.
According to the question,
We have the following information:
Volume of cone = 100 cubic inches
We know that the following formula is used to find the volume of cone:
Volume of cone = π[tex]r^{2}h/3[/tex] where r is the radius of the cone and h is the height of the cone
π[tex]r^{2}h/3[/tex] = 100
Now, using the cross multiplication method:
π[tex]r^{2}[/tex]h = 100*3
Dividing both sides of the equation by πh:
[tex]r^{2}[/tex] = 300/πh
r = 10√(3/πh) inches
We can also solve it further by putting the value of π.
Hence, the radius of the cone is 10√(3/πh) inches when the volume of the cone is 100 cubic inches.

The calculation of the ending inventory and the cost of goods sold using FIFO and LIFO methods for ABC Inc. is as follows:
FIFO LIFO
Ending inventory $10,250 $12,800
Cost of goods sold $17,000 $14,450
How does FIFO differ from LIFO?FIFO (First-in, First-out) assumes that the physical flow of goods sold depends on the chronological order of acquisition.
LIFO (Last-in, First-out) assumes that the cost of goods sold should be based on the latest inventory purchases.
Date Description Units Unit Costs Total Cost
April 1 Beginning inventory 220 $50 $11,000
April 5 Purchases 100 $60 6,000
April 10 Purchases 50 $45 2,250
April 16 Sales -300 $80
April 25 Sales -20 $95
April 30 Purchases 200 $40 8,000
Total 570 $27,250
Units sold 320
Ending inventory 250
FIFO:
Ending Inventory = $10,250 (200 x $40 + 50 x $45)
Cost of goods sold = $17,000 ($27,250 - $10,250)
LIFO:
Ending Inventory = $12,800 (220 x $50 + 30 x $60)
Cost of goods sold = $14,450 ($27,250 - $12,800)

The 30 feet by 15 feet dimension of the old stage and the 1,000 square feet of the new stage generates equations that gives the depth of the new stage;
The depth of the new stage is 25 feetWhat is an equation?An equation states the relationships between two expressions as being of the same value.
The width and depth of the concert hall for the old stage are 30 feet and 15 feet respectively
Area of the new stage = 1000 ft.²
The dimensions of the new stage are;
Width = 30 + x
Depth = 15 + x
Which gives;
(30 + x) × (15 + x) = 1,000
(30 + x) × (15 + x) - 1,000 = 0

The length of the second rectangle is 8 in
How to find the length of the second painting?Since we have painting with an area of 48 in.² and a length of 6 inches, since it is a rectangle, its area is A = LW where
L = length of rectangle = 6 in and W = width of rectangleSo, making Wsubject of the formula, we have
W = A/L
Since
A = 48 in² and L = 6 inSubstituting these into the equation, we have
W = A/L
W = 48 in²/6 in
W = 8 in
Now, since the second painting with an area of 64 in.² it has the same width as the first painting, since it is also a rectangle, its area is A = LW where
L = length of rectangle and W = width of rectangleSo, making L subject of the formula, we have
L = A/W
Since
A = 64 in² and W = 8 inSubstituting these into the equation, we have
L = A/W
L = 64 in²/8 in
