Answer:
1) x = 4
2) ? = 20
8) x = 5
Step-by-step explanation:
Use the applicable relationships to write an equation involving the unknown. Solve the equation.
__
1) We note that the marked arcs are the same length. In a circle, chords that subtend arcs of the same measure are the same length.
5x -1 = 4x +3
x = 4 . . . . . . . . . . add 1-4x to both sides
__
2) A tangent meets a radius at right angles. The given triangle is a right triangle, so the Pythagorean theorem applies.
12² +16² = x²
144 +256 = x² = 400
x = √400 = 20
The missing value is 20.
__
8. Tangents from the same point are the same length.
4x -8 = 12
4x = 20 . . . . . add 8
x = 5 . . . . . . . divide by 4
_____
Additional comment
In problem 2, you note the ratio of side lengths is 12 : 16 = 3 : 4. This should give you a clue that this is a 3-4-5 right triangle. The long (missing) side will be 5, scaled by the scale factor of 4, so will be 4×5 = 20.

Answer:
H. 200 miles in 4 hours.
Step-by-step explanation:
200 miles in 4 hours.
In this situation, in 4 hours, the vehicle has driven a distance of 200 miles.
To determine the distance in one hour, divide the miles by the hour.
200 ÷ 4 = 50.
The vehicle drives at a constant rate of 50 miles per hour.

Answers
Answer:
Step-by-step explanation:
F = 9/5C + 32
Putting value
9/5(49) + 32
88.2 + 32
= 120.2°F
Option E is the correct answer
The Celsius temperature 49 in Fahrenheit is 120 F.
To convert Celsius to Fahrenheit, you can use the formula:
F = (C × 9/5) + 32
Let's calculate the conversion using the given Celsius value:
C = Celsius temperature
F = (C × 9/5) + 32
F= (49 x 9/5)+ 32
F= 88.2 + 32
F = 120.2 F
Thus, Celsius temperature 49 in Fahrenheit is 120 F.

pedro's car averaged 957 miles on its 29-gallon tank of gas. If pedro runs out of gas and a mechanical comes to his rescue with 2 3/4 gallons of gas, determine how far his car can go. Round to the nearest
Answers
Answer:
His car can go 90.75 miles.
Step-by-step explanation:
We solve this question using proportions.
Pedro's car averaged 957 miles on its 29-gallon tank of gas.
This means that per gallon, his car can go:
957/29 = 33 miles.
2 3/4 gallons of gas
[tex]2 + \frac{3}{4} = 2 + 0.75 = 2.75[/tex] gallons.
Determine how far his car can go.
For each gallon, the car goes 33 miles. He has 2.75 gallons, so his car can go 33*2.75 = 90.75.
His car can go 90.75 miles.

Find the number of distinct arrangements of the 9 letters in SEVENTEEN. Two of the same letter are considered identical (not distinct).
Answers
The number of distinct arrangements of the 9 letters in SEVENTEEN is 7560
The number (n) of letters in SEVENTEEN is given as:
[tex]n = 9[/tex]
The repeated letters are E and N, and their frequencies are:
[tex]E=4[/tex]
[tex]N = 2[/tex]
So, the number of distinct arrangements is calculated as:
[tex]Arrangements = \frac{n!}{E!N!}[/tex]
Substitute values for n, E and N
[tex]Arrangements = \frac{9!}{4! \times 2!}[/tex]
Expand the factorials
[tex]Arrangements = \frac{362880}{24 \times 2}[/tex]
[tex]Arrangements = \frac{362880}{48}[/tex]
Evaluate the quotient
[tex]Arrangements = 7560[/tex]
Hence, the number of distinct arrangements is 7560

where
l = lengthw = widthh = heightTherefore,
surface area of the first prism = 8 ft²
surface area of the second prism = 200 ft²

The option price is $6000
Destination fees are $800
The base sticker price is 90% of the price i.e.
[tex]\Rightarrow 90\%\times 40,000\\\Rightarrow 0.9\times 40,000\\\Rightarrow \$36,000[/tex]
The option price is 80% of included options i.e.

What is the horizontal asymptote of the function F(x)=(x-2)/(x-3)^2
O y = 0
O y = 1
O y = 2
oy=3
Answers
The horizontal asymptote of the function f(x) = (x - 2)/(x - 3)²is;
A: y = 0
We are given the function;
f(x) = (x - 2)/(x - 3)²
Expanding the denominator gives us;
f(x) = (x - 2)/(x² - 6x + 9)
The rules for a horizontal asymptote are;
If the degree of the polynomials in both denominator and numerator of a rational function are the same, then the horizontal asymptote will be expressed as the quotient of coefficients of the highest degree terms.If the polynomial of the denominator has a larger degree than the numerator, then the horizontal asymptote will be y = 0.In our given expression, we can see that the degree of the denominator polynomial is greater than that of the numerator and as such the horizontal asymptote is y = 0.
