The normal cruising speed of a certain airplane is about 170 m/sec. What is this speed in miles per hour?
The speed of airplane in miles per hour (mph) is 380.2968 .
What is speed?
Speed is the time rate at which an object is moving along a path. The SI unit of speed is meter per second ( m/s ). Miles per hour ( mph ) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour.
Given that
Speed of a certain airplane = 170 m/s or m[tex]s^{-1}[/tex]
We know that
In 1 meter = 0.0006214 miles
In 1 sec = [tex]\frac{1}{3600}[/tex] hour
but 1 [tex]sec^{-1}[/tex] = 3600 hour
Speed of this airplane in miles per hour = 170 × 0.0006214 × 3600 mph
= 0.105638 × 3600 mph
= 380.2968 mph
Hence, the speed of airplane in miles per hour (mph) is 380.2968 .

Find the volume of each figure. Round your answers to the nearest whole, if necessary.
Given that
The figure is of a cone and we have to find the volume of the cone.
Explanation -
The diameter of the cone is 22km and the height is also 22 km.
So the radius will be
radius = r = d/2 = 22/2 km = 11 km
Hence, r = 11 km and h = 22 km
The formula for the volume of the cone will be
[tex]Volume=\frac{1}{3}\times\pi\times r^2h[/tex]On substituting the values we have
[tex]\begin{gathered} V=\frac{1}{3}\times\pi\times11^2\times22\text{ km}^2 \\ \\ V=\frac{1}{3}\times\frac{22}{7}\times11\times11\times22\text{ km}^2 \\ \\ V=\frac{58564}{21}\text{ km}^2=2788.7\text{ km}^2 \end{gathered}[/tex]So B is the correct option.
Final answer -
Hence the final answer is 2788 sq km.Calculate the future value of the $9,000 earning 9% interest compounded quarterly for 8 years round answer to two decimal places
Compound interest formula:
A = P (1 + r/n )^nt
Where:
A = future vale
P= Principal investment = 9,000
r = interest rate in decimal form = 9/100 = 0.09
n = number of compounding periods = 4
t = years = 8
Replacing:
A = 9000 ( 1 + 0.09/4)^ (4*8)
A = 9000 (1.0225)^32
A= 18,342.93
The future value is $18,342.93

across which axis was point F reflectedF(10, -5) - F'(-10, -5)
y-axis
Explanations:When a figure is reflected about any axis, the coordinate of that axis still remains the same, but the coordinate of the other axis is negated
For example:
If the point A(x, y) is reflected about the x-axis, the reflected image becomes A' (x, -y)
If the point A(x, y) is reflected about the y axis, the reflected image becomes A'(-x, y)
In this exercise, the point F(10, -5), after reflection, becomes F' (-10, -5)
Since the y-axis still remains -5 after reflection, this means that the point F was reflected across the y-axis.
1. An angle in a right triangle is identified as θ. If the tangent of θ equals one, what must be true about the triangle side lengths?
A. The side adjacent to theta is half the length of the hypotenuse.
B. The side opposite to theta is longer than the adjacent side.
C. The sides opposite and adjacent to theta are the same length.
D. The side adjacent to theta is longer than the adjacent side.
If the tangent of θ equals one (1), the true statement about the right-angled triangle side lengths is that: C. The sides opposite and adjacent to theta are the same length.
What is a tangent?In geometry, a tangent is also referred to as a tangent line and it can be defined as a straight line that touches a plane curve at a specific point.
Mathematically, the tangent of an angle is given by this expression:
Tanθ = Opp/Adj
Where:
Opp represents the opposite side of a right-angled triangle.Adj represents the adjacent of a right-angled triangle.θ is the angle.For this right-angled triangle, the tangent of the angle (θ) is given by:
Tanθ = Opp/Adj = 1
Opposite/Adjacent = 1
Cross-multiplying, we have:
Opposite = Adjacent
In conclusion, the opposite side length of this right-angled triangle is equal to its adjacent side length.

The required expression equivalent to the given expression is 3²² .
An expression in mathematics is said to be algebraic if it was constructed using integer variables, constants, and algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)
However, transcendental numbers like such and e are not algebraic because they are not created from integer constants and algebraic operations.While the definition of e necessitates an infinite number of algebraic operations, the generation of is frequently expressed as a geometric expression.If an expression can be reduced to a reasonable fraction using the features of arithmetic operations, it is said to be rational (commutative properties and associative properties of addition and multiplication, distributive property and rules for the operations on the fractions).Given : the expression of the form ( 3 ⁴ ) ⁶ ÷ 3²

Pedro has scores of 95, 84, 68, 92 after four tests. what score must he make on his fifth test to have an average of 78 or greater?
Answer:
51 or above
Step-by-step explanation:
He already averages more then 78. But he at least needs a 51 in order for him to average 78. For him to get more than that he just needs a 52 or higher.
78 x 5 = 390
95 + 92 + 84 + 68 = 339
