The value of t using straight line angle is 24°.
What is straight line angle ?
A straight angle in geometry is one that has a length of 180 degrees. Because it seems to be a straight line, it is known as a straight angle. In other words, it is an angle whose sides extend in the same straight line in directions opposite to the vertex.
In mathematics, a straight angle is defined as an angle with a degree value of 180. It looks to be a straight line, hence the name "straight." In essence, two rays linked end to end create an angle according to the mathematical concept of angles. As a result, the two rays of the 180-degree angle are subtended in the direction of their endpoints, which are in the opposite direction.
Here we know that sum of angle in straight line at any point is 180° .
Then,
=> (4t-7)°+83°=180°
=> 4t-7+83 = 180
=> 4t+76 = 180
=> 4t = 180-76 = 104
=> t = 104/4 = 26°
Hence the value of t=24°

What is simple interest?
The principal of a loan or the first deposit into a savings account serves as the basis for simple interest. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.
P=$26,000 r=2.6%=0.026
A=2P=2(26,000)=$52,000
A=P+Prt
Substitute the known values
52,000=26,000+(26,000×0.026t)
52,000-26,000=676t
On simplifying, we get t= 38.46 years

How many three-letter "words" can be made from 10 letters "FGHIJKLMNO" if repetition of letters (a) is allowed? Your answer is (b) is not allowed? Your answer is
Answers
a. The number of permutations of three letter words that can be formed with repetition is 1000 words
b. The number of permutations of three letter words that can be formed without repetiton is 720 words
What are permutations?Permutations are the number of ways in which x objects can be arranged out of n objects.
The number of permutations is given by ⁿPₓ = n(n - 1)(n -2)...(n - x + 1)
a. How to find the number of ways in which the 10 letters can be arranged if repetition is allowed?Since we require the number of three-letter "words" can be made from 10 letters "FGHIJKLMNO" with repetition, we note that there are 10 letters.
Since repetition is allowed, for the first slot, we have 10 letters, for the second position, we have 10 letters and for the third position, we have 10 letters.
So, the total number of permutations is n = 10 × 10 × 10
= 1000 words
So, the number of three letter words that can be formed is 1000 words
b. How to find the number of ways in which the 10 letters can be arranged if repetition is not allowed?Since we require the number of three-letter "words" can be made from 10 letters "FGHIJKLMNO" without repetition, we note that there are 10 letters.
Since repetition is not allowed, for the first slot, we have 10 letters, for the second position, we have 9 letters and for the third position, we have 8 letters.
So, the total number of permutations is ¹⁰P₃ = 10 × 9 × 8
= 720 words

A) It is an exponential equation.

Is the data modeling a linear or an exponential equation?Here we have the following data:
(1, 2), (2, 4), (3, 8), (4, 16)
What you can see is that the x-value of the points increases equially between consecutive pairs (increases of one unit).
while the y-value does not do that.
First, it increases by 2, then by 4, then by 8.
So this is an exponential relation.
B) A general exponential will be of the form:
y = a*(b)^x
Usin the first two pairs (1, 2) and (2, 4) we can write two equations:
2 = a*b^1 = a*b
4 = a*b^2
So we have a little system of equations:
2 = a*b
4 = a*b*b
If we take the second equation and we divide that by the first one we get:
4/2 = (a*b*b)/(a*b)
2 = b
Replacing that in the first equation we get:
2 = a*2
2/2 = a = 1
The equation is:
y = 2^x
C) The average rate of change will be:
R = (2^4 - 2^2)/(4 - 2) = (16 - 4)/2 = 12/2 = 6

Using the Pythagorean Theorem, the approximately length of ladder is 20.6 feet
As we know Michael is standing on roof of his house.
He stands 5 feet away from his house
The ladder touches the point 20 feet above the ground and where the Michael standing
In this order we have to find the approximately length of ladder
From this question we can clearly figure out that in this question we have:
Perpendicular= 20 feet
Base = 5 feet
So as we can understand that we have to use Pythagorean Theorem
Pythagorean Theorem:
(Hypotenuse)^2 = (Perpendicular)^2+(Base)^2
(Hypotenuse)^2 = (20)^2+(5)^2
(Hypotenuse)^2 = 400+25
(Hypotenuse)^2 = 425
Hypotenuse=square root(425)
Hypotenuse=20.6 feet
Hence, the approximately length of ladder is 20.6 feet

A road drops 795 feet for every 265 feet forward, determine the slope of the road. The

Answers
The slope of the road is 159/53
What is a slope?
How steeply a line slopes from left to right is known as its slope. By dividing a line's rise, or vertical change, by run, or horizontal change, one can calculate a line's slope, the slope of a line is always constant (it never varies).
To calculate the slope of a line using the formula
m = rise / run = (y₂ - y₁)/(x₂ - x₁)
where, m = slope
(x₁, y₁) = coordinates of the first point in the line
(x₂, y₂) = coordinates of the second point in the line
Here, we have
rise = 795
run = 265
by using the slope formula,
m = rise/run
m = 795/265
m = 159/53
Hence, the slope of the road is 159/53.

Answers
a) Length of Fence = 50 meters
b) Weight of Grass Seeds = 20 kg
c) Area of Carriageway = 516 sq. meters
d) Time taken by the Striping Car = 7.6 minutes
What is a Circle?
A circular plane figure with a circumference made up of points equidistant from a given point (the center).
Solution:
a) To calculate the length of fence we need to find the circumference of the inner circle
Circumference of Circle = 2*22/7 *Radius
Circumference of Circle = 2 * 22/7 * (16)/2
Circumference of Circle = 50.24
So, the length of fence is 50 meters approx
b) To calculate the the total weight of grass we need to first find the area of the inner circle
Area of Circle = 22/7 * (Radius)^2
Area of Circle = 22/7 * (16)^2
Area of Circle = 22/7 * 256
Area of Circle = 803.84 meter sq.
For 1 meter sq. = 25 grms of grass seeeds are required
So, for 804 meters = 25*804 = 20100 grams
20100 grams = 20.1 kg = 20 kg (approx)
c) The are of Inner Carriageway will be calculated by substracting the area of inner circle from outer circle
Area of Outer Circle = 3.14 * (16+4.5)^2
Area of Outer Circle = 1320 sq. meters (approx)
Area of Inner Circle = 804 sq. meters (approx) #we have calculated it above
Area of Carriageway = 1320 - 804 = 516 sq. meters (approx)
d) Speed of Stripping Car = 25 cm/sec
Circumference of the part to be stripped = 2*3.14*(16+2.25)
Circumference = 115 meters approx. = 11500 cm
Time = Distance / Speed
Time = 11500/25 = 460 seconds

B) The value of x in 27^(4x-6) =(1/9)^(2x-7), is x = 2
Solving equations: Determining the value of xFrom the question, we are to solve the given equations
The given equation is log₄(x² - 12x + 48) = 2
From one of the laws of logarithm, we have that
logₐ x = n ⇒ x = aⁿ
Thus,
log₄(x² - 12x + 48) = 2 becomes
(x² - 12x + 48) = 4²
x² - 12x + 48 = 16
x² - 12x + 48 - 16 = 0
x² - 12x + 32 = 0
Solve the quadratic equation
x² - 12x + 32 = 0
x² - 8x - 4x + 32 = 0
x(x - 8) -4(x - 8) = 0
(x - 4)(x - 8) = 0
x - 4 = 0 OR x - 8 = 0
x = 4 OR x = 8
B) 27^(4x-6) =(1/9)^(2x-7)
Solve for x
27^(4x-6) =(1/9)^(2x-7)
Express the bases in index form
3^3(4x-6) =(3)^-2(2x-7)
Equate the powers
3(4x - 6) = -2(2x - 7)
12x - 18 = -4x + 14
12x + 4x = 14 + 18
16x = 32
Divide both sides by 16
16x/16 = 32/16
x = 2

The amount of each semiannual interest payment is $7200.
Given that,
A company issues 9%, 4-year bonds with a par value of $160,000 on January 1 at a price of $165,386, when the market rate of interest was 8%. The bonds pay interest semiannually.
Simple interest is defined as the percentage of earnings on the lending for a period of time
Here,
Value of a single bond = $160,000
Issue price of bond = $165, 386
Rate of interest = 9%
the market rate of interest = 8%
Interest payment = Semi-annually
Semi-annual interest payment = Value of the single bond × rate of interest/2
