4. On a 3-hour trip, a car travels 156 miles.
What is the average speed of the car on this
trip?
Answer:
v = 52 mph
Step-by-step explanation:
Given that,
The distance travelled by the car, d = 156 miles
Time, t = 3 hour
We need to find the average speed of the car. The formula for the average speed is given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{156}{3}\\\\v=52\ mph[/tex]
So, the average speed of the car is equal to 52 mph.

please i need HELP x+y=15 , x-y=3
and
Answer:
x=9
y=6
Step-by-step explanation:
x+y=15 .............(i)
x-y=3...........(ii)
Subtracting equation (ii) from equation (i)
or, x+y -(x-y)=15-3
or, x+y-x+y=12
or, 2y=12
or, y=12/2
∴y=6
Now,
Putting the value of y on equation (i),
or, x+6=15
or, x=15-6
∴x=9
Evaluate the expression for the value given.

Find the length of a side of a square if its area is:
0.49 square units
Answer:
Side = 0.7 units
Step-by-step explanation:
Area of a square = 0.49 sq. units
Side² = 0.49
side² = [tex]\frac{49}{100}\\\\[/tex]
[tex]side = \sqrt{\frac{49}{100}}=\sqrt{\frac{7*7}{10*10}}\\\\sides=\frac{7}{10}=0.7[/tex]

An auditorium has 21 rows of seats. The first row has 18 seats and each succeeding row has 2 more seats than the previous row. How many seats are in the auditorium?
Answer:
798
Step-by-step explanation:
So, 21*{2*18 + (21-1)*2}/2
= 21*{36 + 20*2}/2
= 21*{36+40}/2
= 21*76/2
= 1596/2
= 798
Total number of seats is 798
Given that;Number of seats in first row = 18
Number of rows = 21
Each row added number of seats then previous = 2
Find:Total number of seats
Computation:Total number of seats = Sn = (n/2)[2a + (n-1)d]
Total number of seats = Sn = (21/2)[2(18) + (21-1)2]
Total number of seats = (21/2)[36 + (20)2]
Total number of seats = (21/2)[36 + 40]
Total number of seats = (21/2)[76]
Total number of seats = (21)(38)
Total number of seats = 798

The measure of central angle RST is r radians.
What is the area of the shaded sector?
A. 41π units^2
B. 8π units^2
C. 16π units^2
D. 20π units^2
The area of the shaded sector of the circle is 16π units².
How to find the area of a circle?Suppose the circle has radius of 'r' units, then, its area is given as:
[tex]A = \pi \times r^2[/tex]
sq. units
Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:
[tex]\pi \times (\dfrac{d}{2})^2[/tex]
sq. units
We are given that;
θ = r radians
r = 4 units
Now,
To convert radians to degrees, we use the formula:
Degrees = Radians × 180°/π
So,
θ = r × 180°/π
Substituting these values in the formula for area of a sector, we get:
Area of a sector = (r × 180°/π / 360°) × π(4)²
Simplifying, we get:
Area of a sector = r² units²
=16π units².
Therefore, by the area of a circle the answer will be 16π units².
