39 Minutes
Step-by-step explanation:
Given data
Total time for the car trip= 56minutes
Stoppage time= 17 minutes
Hence the time left for the trip
=Total time- Stoppage time
= 56-17
=39 Minutes
I need help with circle similarity / scale factor. can someone please help me out?
Answer:
A scale factor exists because any two circles are similar. You can use the radii to determine the scale factor.
Step-by-step explanation:
The ratio between the radii is 31 so the scale factor is 31=3. The circumference of the smaller circle is C=2π(1)=2π.

What is the area of the trapezoid?
A. 24 mm2
B. 26 mm2
C. 32 mm2
D. 40 mm2
Answer:
A= 24 m
Step-by-step explanation:
The formula for the area of a trapezoid is A= [tex]\frac{a+b}{2}[/tex] x h.
Using the formula you plug in the values:
A= [tex]\frac{4 + 12} 2}[/tex] x 3
2. Now you simplify the equation and solve
A = [tex]\frac{16}{2}[/tex] x 3
A = 8 x 3
A = 24
Solve the equation:
[tex]2 {x}^{2} + 7x - 3 = 0[/tex]
Answer:
[tex]delta = {7}^{2} - 4 \times 2 \times ( - 3) \\ = 49 + 24 = 73 \\ x 1= \frac{ - 7 + \sqrt{73} }{4} \\ x 2= \frac{ - 7 - \sqrt{73} }{4} [/tex]

The cities of Raleigh, Durham, and Fuquay-Varina approximate a right triangle. The distance from Raleigh to Durham is 24 miles. The distance from Raleigh to Fuquay-Varina is 18 miles. What is the distance from Durham to Fuquay-Varina?
Answer:
The distance from Durham to Fuquay-Varina is 30 miles.
Step-by-step explanation:
Given that the cities of Raleigh, Durham, and Fuquay-Varina approximate a right triangle, and the distance from Raleigh to Durham is 24 miles, while the distance from Raleigh to Fuquay-Varina is 18 miles, to determine what is the distance from Durham to Fuquay-Varina, the following calculation must be performed, applying the Pythagorean theorem:
18 ^ 2 + 24 ^ 2 = X ^ 2
324 + 576 = X ^ 2
√ 900 = X
30 = X
Therefore, the distance from Durham to Fuquay-Varina is 30 miles.

For which pair of functions is (gof)(a) = al-2? O f(a) = a? – 4 and g(a) = Va o fla) = 3a-1 and g(a) = 2a - 2 O f(a) = 5 + a² and g(a) = a-5-2 O f(a) = 3 - 3a and g(a) = 4a - 5
Step-by-step explanation:
f(a)=1/2-1 and g(a)=2a-2
The pair of functions that gives
f(a) = 5 + a² and g(a) = √(a - 5) - 2 is (g o f) (a) = |a| - 2.
Option C is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the process are 1 and 2.
We have,
f(a) = a² - 4 and g(x) = √a
(g o f) (a)
= g (f(a))
= g (a² - 4)
= √(a² - 4)
f(a) = (1/2)a - 1 and g(a) = 2a - 2
(g o f) (a)
= g (f(a))
= g ((1/2)a - 1)
= 2 x ((1/2)a - 1) - 2
= a - 2 - 2
= a - 4
f(a) = a² - 4 and g(a) = √a
(g o f) (a)
= g (f(a))
= g (a² - 4)
= √(a² - 4)
f(a) = 5 + a² and g(a) = √(a - 5) - 2
(g o f) (a)
= g (f(a))
= g (5 + a²)
= √((5 + a² - 5) - 2
= √a² - 2
= |a| - 2
f(a) = 3 - 3a and g(a) = 4a - 5
(g o f) (a)
= g (f(a))
= g (3 - 3a)
= 4(3 - 3a) - 4
= 12 - 12a - 4
= 8 - 12a
Thus,
The pair of functions that gives
f(a) = 5 + a² and g(a) = √(a - 5) - 2 is (g o f) (a) = |a| - 2.

Pascal wants to find the sum of the measures of the interior angles of a polygon that has n sides. How could he do this? Multiply 180 degrees by n. Multiply 180 degrees by (n + 2) Multiply 180 degrees by (n minus 2) Multiply 180 degrees by 2.
Answer:
Multiply 180 degrees by (n minus 2)
Step-by-step explanation:
Number of sides in the polygon = n
Polygons have sides 3, 4, 5, 6.....
Polygon with 3 sides is a triangle
Polygon with 4 sides is a quadrilateral
Sum of it's Interior angles = (n-2) × 180°
For a 3 sided polygon
Sum of it's Interior angles = (n-2) × 180°
= (3 - 2) × 180°
= 1 × 180°
= 180°
For a 4 sided polygon
Sum of it's Interior angles = (n-2) × 180°
= (4 - 2) × 180°
= 2 × 180°
= 360°
Answer:
Multiply 180 degrees by (n minus 2)

Answer:
1. a = 5, b = 8
2. d = 2
Step-by-step explanation:
1. The sum of two adjacent angles of a parallelogram is 180 degrees
Hence,
[tex]14a-5+115 = 180 \\14a = 180 -110\\a = 70/14\\a = 5[/tex]
Like wise
[tex]8b+1+115 = 180 \\8b = 180 -116\\8b = 64\\b = 8[/tex]

y = 7x + 15
Step-by-step explanation:
The y-value when x=0 is the y-intercept: b=15.
The difference between the y-value at x=1 and that y-intercept is the slope: m=22-15=7.
Using these in the formula for the line, we have ...

If the discriminant of an equation is positive, which of the following is true of the equation
A it has one complex solution
B it has one real solution
C it had two real solutions
D it has two complex solutions
Answer:
C it has two real solutions
Step-by-step explanation:
If the discriminant of a quadratic equation is positive, it means that the graph intersects the x-axis, and hence produces two real solutions.
If the discriminant is zero, then the graph is tangential to the x-axis, and there will be two real coincident solutions.
If the discriminant is negative, then there are two complex solutions.

C

The force F needed to loosen a bolt with a wrench varies inversely with the lenth I of the handle. Write an
equation relating Fand I given that 250 pounds of force must be exerted to loosen a bolt when using a wrench
with a handle 6 inches long. How many pounds of force must be exerted when using a wrench with a handle 24
inches long? Round to 1 decimal place.
F =
pounds of force
Answer:
Step-by-step explanation:
We first need to determine what the model is for this situation. Using the inverse proportion equation, which is
[tex]F=\frac{k}{l}[/tex], we can find that model using the information given.
We first need to solve for k, the constant of proportionality. Using F = 250 and l = 6,
[tex]250=\frac{k}{6}[/tex] and
multiply both sides by 6 to get that
k = 1500
Now we use that k value along with l = 24 to solve for the force needed:
[tex]F=\frac{1500}{24}[/tex] so
F = 62.5 pounds
