What is simple interest?Simple interest is a quick and easy way to calculate the interest on a loan. Simple interest is calculated by multiplying the daily interest rate by the principal multiplied by the number of days between payments.Here,
The total amount is determined by:
F=I(1+rt)
Where
I is the initial sum.r is the interest rate. t stands for time interval.F represents the total amount.Here given ,
r = 1.2%
t = 7
F = $126
As a result,
I = F/(1+rt)
= 126/1+1.2*7

Using the alternate exterior angles theorem, the value of x is: 127°.
What is the Alternate Exterior Angles Theorem?When two parallel lines are intersected by a transversal to form alternate exterior angles that lie outside on each of the parallel lines, the alternate exterior angles theorem states that both angles are equal or congruent to each other.
From the diagram given, we are told that line m is parallel to line n. transversal t crosses both lines and n. The angles, x and 127 degrees are alternate exterior angles that lie on each parallel lines.
Therefore, the alternate exterior angles theorem states that, both angles would be equal.
Thus, we can conclude that, x = 127°.

When two straight lines or rays intersect at a single endpoint, an angle exists formed. If 2 and 3 exists complements, and m2= 55°, then m3 = 90 - 55 = 35 degrees.
What is meant by angle?When two straight lines or rays intersect at a single endpoint, an angle exists formed. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
Complements sum to 90 degrees.
If 1 and 2 are complements and m1 = 35°, then
m2 = 90 - 35 = 55 degrees.
Now if 2 and 3 are complements, and m2= 55°,
then m3 = 90 - 55 = 35 degrees.
The complete question is:
Given: 1 and 2 are complements, 2 and 3 are complements, and m1 = 35°. Prove: m3 = 35° Complete the missing parts of the paragraph proof. By then, we know that angle 1 is congruent to angle 3. The measure of angle 1 equals the measure of angle 3 by the definition of angles. Then, using the property, the measure of angle 3 is the degree.

The length of a rectangular sign is 12 ft less than twice its width. Its perimeter is 144 ft. Find the length and the width of the sign.
The rectangular sign is 30 feet in length and 42 feet in width.
The perimeter of the rectangular sign = 144 ft
Let the width of the rectangular sign be x, and the length of the sign will be x-12
The formula for the perimeter of the rectangle:
P = 2(l+w)
where P = perimeter of the rectangle
l = length of the rectangle
w = width of the rectangle
Substituting the values in the formula we get:
144 = 2(x-12+x)
144 = 2(2x-12)
144 = 4x -24
168=4x

the volume of a cube shaped crate i 27 cubic feet. what is the length of one edge of the crate?
Answer: The length of the edge of the crate is 3 feet.
Step-by-step explanation:
The formula of the volume of a cube is the cube of edge length.
The volume of the cube (V) = (edge)³ ...................................(1)
In the given question volume is 27 cubic feet.
So, V = 27 cubic feet
Now we replace the Volume with the edge using equation (1)
i.e. (edge)³ = 27
or we can say that the cube root of the edge is equal to 27
i.e. edge = ∛27
which is equal to 3
hence, edge = 3 feet
To calculate the cube root write prime factors of 27 and group them in groups of three
i.e. ∛27 = ∛(3×3×3) = ∛ (3)³ = 3

Based on the fact the game of hearts, four players are each dealt 13 cards from a deck of 52
The domain is the deck of 52 cardscodomain is 4 playersfunction, f(k) maps a card to each playerIt is surjectiveThis is further explained below.
What is a surjective Function?A surjective function is a kind of function that exists in mathematics that ensures that any element y may be transferred to element x in such a way that f(x) equals y.
To put it another way, each element that makes up the function's codomain is the mirror image of at least one element that makes up the domain.
Generally, function, f(k) maps a card to each player
And since each player is dealt 13 cards st 13 of the cards are mapped to each player.
It is a function as one card is mapped to one and only one player.
The function is not injective because 13 cards 1 are mapped to one player so it is a many-one function but the injective function does not map two elements to a common clement.
In conclusion, It is surjective as each player is dealt 13 cards. the function is not injective hence rot bijective.

it is 111
The width of Michelle's room is 111 inches.
How to find the width of a rectangle?The ratio of the length to the width is 4:3.
The width of her room can be calculated as follows:
Therefore,
length = 12 ft 4 inches
Hence.
1 ft = 12 inches
12 ft = 144 inches
Hence,
length = 144 + 4 = 148 inches
Therefore,
x = length + width
4 / 7 × x = 148
4x / 7 = 148
cross multiply
4x = 148 × 7
4x = 1036
x = 1036 / 4
