Answer:
Sam average speed for the whole journey = [tex]3\frac{3}{11} mph[/tex]
Step-by-step explanation:
Formula: Speed = [tex]\frac{Distance}{Time}[/tex]
i.e. Time = [tex]\frac{Distance}{Speed}[/tex]
If Sam walked x miles at 4 mph, then time taken by him = [tex]\frac{x}{4}[/tex] hours
If he then walked 2x miles at 3 mph, then time for this period = [tex]\frac{2x}{3}[/tex]hours
Average speed = [tex]\frac{Total Distance}{Total Time}[/tex]
=[tex]\frac{x+2x}{\frac{x}{4} \frac{2x}{3} }[/tex]
=[tex]\frac{3x}{\frac{x1}{4} \frac{2}{3} }[/tex]
=[tex]\frac{3}{\frac{3+8}{12} }[/tex]
=[tex]\frac{3 x 12}{11}[/tex]
=[tex]\frac{36}{11}[/tex]
=[tex]3\frac{3}{11} mph[/tex]
Hence, Same's average speed for the whole journey = [tex]3\frac{3}{11} mph[/tex]
What is the meaning of the point with an x-coordinate of 2?
Answer:
In 2 seconds, the space station travels 10 miles.
Step-by-step explanation:
Well, if the x axis represents time in seconds and the y axis represents distance in miles, then when your x value is 2, your y value is 10.
Geometry- remember what we know about verticale angles and solve for X. Then tell me the measure of angle A.
Answer:
m<A = 32°
Step-by-step explanation:
When angles are vertical, it means they are equal to each other:
m<A = m<C
4x - 8 = 2x + 12
4x - 2x = 12 + 8
2x = 20
x = 20/2
x = 10
Solve for A:
4x - 8
4(10) - 8
40 - 8

a rectangular hall is 16 m tall and 12 metre wide. how many marble slabs of size 25 CM X 15cm needed to cover the floor of the hall?
Answer:
5120 tiles.
Step-by-step explanation:
Do one thing.
Find out the area of the rectangular hall.
Find out the area of the marble slab.
Remember, the units are to be made same.
Now, to know the number of marble tiles required to fill the hall, you just have to divide the area of the hall with the area of the marble tile.
Calculations-
Area of the rectangular hall = length x width = 1600 x 1200 (we converted 'm' to 'cm') = 1920000 sq. cm.
Area of one marble tile = 25 x 15 = 375 sq. cm.
Now you divide the numbers and get 5120 tiles.

Write the expression as a single logarithm.
log₄ 2x - log₄ 6y
Answer:
[tex]log_{4}(\frac{2x}{6y})[/tex]
Step-by-step explanation:
According to the Quotient Rule (Logarithmic Property):
[tex]log_{a}x - log_{a}y = log_{a}(\frac{x}{y})[/tex]
Therefore, you could combine the logarithmic expressions as:
[tex]log_{4}2x - log_{4}6y = log_{4}(\frac{2x}{6y})[/tex]
Optional:
If ever you're required to simplify it further, [tex]log_{4}(\frac{2x}{6y})[/tex] will be:
[tex]log_{4}(\frac{2x}{6y}) = log_{4}(\frac{x}{3y})[/tex]

A garden is in the shape of a trapezium whose parallel sides are 40m and 22m and the perpendicular distance between them is 12m. Find the area of the garden
Answer:
A = 372 m²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₁ the parallel bases
Here h = 12, b₁ = 40 and b₂ = 22 , then
A = [tex]\frac{1}{2}[/tex] × 12 × (40 + 22) = 6 × 62 = 372 m²
