Answer:

9\frac{1}{2}\times5\frac{3}{10}=50\frac{7}{20}

Step-by-step explanation:

Accoding to given question,

9\frac{1}{2}\times5\frac{3}{10}

Converting mixed fraction into fraction,

\frac{19}{2}\times\frac{53}{10}

Solving further we get,

\frac{1007}{20}

=50\frac{7}{20}

Thus, 9\frac{1}{2}\times5\frac{3}{10}=50\frac{7}{20}

The distance between the cities Atlanta and Indianapolis is 540 miles. A motorcycle's speed is 48 mph. For a car it takes 2.25 h
bezimeni [28]

Answer:


Step-by-step explanation:

let they travel the distance between them alone

d = common distance traveled by both motorcycle and car = 540 miles

t_{m}= time taken by motorcycle to travel distance between them

v_{m} = speed of the motorcycle = 48 mph

time taken by motorcycle to travel distance between them is given as

t_{m}= d/v_{m}

t_{m}=540/48

t_{m}= 11.25 h



t_{c}= time taken by car to travel distance "d" =11.25 - 2.25 = 9 h

v_{m} = speed of the motorcycle

speed of motorcycle is given as

v_{m} = d/t_{m}

v_{m} = 540/9

v_{m} = 60 mph


when the car and motorcycle move towards each other, the relative speed is given as

v = v_{m} + v_{c}

v = 60 + 48

v = 108 mph

t = time taken to meet

Time taken to meet is given as

t = d/v

t = 540/108

t = 5 h

WORTH 30 PTS PLS ANSWER ASAP.
andrew11 [14]
Assuming that X represents the number of hours worked and f(x) the number of cars washed, the equation would be f(x)=11x+14x.

The 11x represents the number of cars washed by Arianna in x number of hours and the 14x represents the number of cars washed by Matthew in x number of hours. You add the two because they are each washing their own car at their own pace but working on one lot.

A 15 foot pole is leaning against a tree. The bottom of the pole is 8 feet away from the bottom of the tree. Approximately how h
mrs_skeptik [129]

Answer:

The top of the pole is approximately <u>13 feet</u> high up the tree.

Step-by-step explanation:

The diagram for the given scenario is shown below.

From triangle ABC, A is the top of pole and B is the bottom of pole.

AC is the height of tree. BC is the distance of the  bottom of pole from the tree.

Given:

AB = 15 ft, BC = 8 ft

To find:

AC = ?

Since triangle ABC is right angled triangle, we apply Pythagoras Theorem to find the unknown side. So,

AC^2+BC^2=AB^2\\\\AC^2+8^2=15^2\\\\AC^2+64=225\\\\AC^2=225-64\\\\AC^2=161\\\\AC=\sqrt{161}=12.7\approx 13\ ft

Therefore, the height of the tree is approximately 13 ft.

A square with sides X ft long has a perimeter of 34.2 How long are the sides of the square?
Ymorist [56]

Answer:

Each side is 8.55

Step-by-step explanation:

The perimeter of a square is given by

P =4s

34.2 = 4s

Divide each side by 4

34.2 /4 = 4s/4

8.55 = s

Each side is 8.55
