Two planes, which are 3400 miles apart, fly toward each other. Their speeds differ by 80mph. If they pass each other in 5 hours,

Andreas93 [3]

Answer : The speed of both planes is 61.25 mph and 18.75 mph respectively.

Explanation:

Let the speed of first plane be x mph

Let the speed of second plane be y mph

Since we have given that difference of speeds is 80 mph

i.e. x - y= 80 ( $Eq^n$ 1)

Distance between two planes = 3400 miles

As they are flying towards each other i.e. they are in the opposite direction.

So, Relative speed will be the sum of their speeds i.e.

Relative speed = x + y

And we know speed = $\frac{Distance}{Time}$

Speed= $\frac{3400}{80}$

⇒ Speed = 42.5 mph

Hence, Relative speed becomes 42.5 mph

⇒ x+y=42.5 ( $Eq^n$ 2)

Now, by using the elimination method of solving the system of equation, we have ,

x= 61.25 mph

and y = 18.75 mph

Lynn is making custom bricks. She combines 39 pounds of water and 48 pounds of brick dust in a mixing bucket. She spills 13 poun

ehidna [41]

Lynn mixes 39 pounds of water with 48 pounds of brick dust, so the mixture has a total weight of 39 + 48 = 87 pounds.

13 pounds are spilled during mixing, so she's left with 87 - 13 = 74 pounds to turn into bricks.

7 pounds are needed for 1 brick, so she can make 10 bricks because 7 • 10 = 70 and 7 • 11 = 77, and 70 < 74 < 77.

If she uses the mixture to make 10 bricks, she uses up 70 pounds of it, which leaves 4 pounds to be washed out.

Mrs. Huynh bought a bag of 3 dozen toy animals as party favors for her son’s birthday party. The bag of toy animals cost $28.97.

Luda [366]

Answer: $price\ of\ each\ toy\approx\$1$

Step-by-step explanation:

Knowing that Mrs. Huynh bought a bag of 3 dozen toy animals. The total number of animals in the bag is:

$3*12=36$

The cost of the bag was $28.97, so you must divide 36 by $28.97 in order to know the price of each toy animal.

To estimate this quotient, the first round the numbers so that they are easier to work with.

We can say that:

$28.97\approx30\\\\36\approx30$

Then:

$30\div30\approx1$

Therefore, you can estimate that the price of each toy animal is:

$price\ of\ each\ toy\approx\$1$
