Emma enjoys flying kites. her red kite has a maximum altitude of 117.46 meters, and her black kite has a maximum altitude of 362

7nadin3 [17]

You have to convert 117.46 meters to feet. so you know that 0.3048 meters is 1 foot.

117.46 / 0.3048= 385.37feet red kite
now you can simply subtract
385.37-362.26=23.11ft
the answer is, the red kite has an altitude 23.11 feet higher then the black kite.

Carlos buys a game for $7.89 and some batteries for $5.49. He pays with a $20 bill. What is the best estimate of how much change

Molodets [167]

Given:

Carlos buys a game for $7.89 and some batteries for $5.49. He pays with a $20 bill.

To find:

The best estimate of the amount of change he should get.

Solution:

First we need to approximate the data values.

$\$7.89\approx \$8.00$

$\$5.49\approx \$5.50$

Now, the total cost of game and batteries is

$\$8.00+\$5.50=\$13.50$

He pays with a $20 bill.

$Change=\$20-\$13.50$

$Change=\$6.50$

Therefore, the estimated amount of change is $6.50.

REINFORCE Tickets to the zoo cost $18 for adults and $8.25 for children. One day, the zoo sold 2,300 tickets and collected $30,1

jenyasd209 [6]

Given:

The cost of adults ticket = $18

The cost of children's ticket = $8.25

Total tickets = 2300

Total revenue = $30,168.

To find:

The number of children and number of adults attended the zoo that day.

Solution:

Let x be the number of children and y be the number of adults.

Equation for tickets: $x+y=2300$ ...(i)

Equation for revenue: $18x+8.25y=30168$ ...(ii)

Plot the graphs of the given equations on a coordinate plane as shown below.

From the graph it is clear that the graph of both equations intersect each other at (1148,1152).

It means the number of adults is 1148 and the number of children is 1152.

It can be solved algebraically as shown below:

Substitute the value of y in (ii) from (i).

$18x+8.25(2300-x)=30168$

$18x+18975-8.25x=30168$

$9.75x=30168-18975$

$9.75x=11193$

Divide both sides by 9.75.

$x=\dfrac{11193}{9.75}$

$x=1148$

Putting $x=1148$ in (i), we get

$1148+y=2300$

$y=2300-1148$

$y=1152$

Therefore, the number of adults is 1148 and the number of children is 1152.

zheka24 [161]

Answer/Step-by-step explanation:

[1] $3rs = 3 * r *s$

[2] $12xy = 2*2*3*x*y$

[3] $5x^2=5*x*x$

[4] $36x^2=2*2*3*3*x*x$

[5] $25^2=5*5*x*x$

[6] $30x^2=2*3*5*x*x$

[7] $5x^3=5*x*x*x$

[8] $24y^3=2*2*2*3*y*y*y$

[9] $9xy=3*3*x*y$

[10] $12x^4=2*2*3*x*x*x*x$

Factoring means to factor a number means to break it up into numbers that can be multiplied together to get the original number.
