8(3x-2)=2(8)+16 explanation how the order of operations is used. How the equation is kept balanced.

Answers

Answer 1

Answer:

See explanation

Step-by-step explanation:

Given;

8(3x-2)=2(8)+16

We clear the brackets

24x - 16 = 16 + 16

24x - 16 = 32

We add 16 to both sides

24x - 16 + 16= 32 + 16

24x = 48

We divide both sides by 24

24x/24 = 48/24

x =2

find the area of the composite figure

Answers

You split it into a triangle and a rectangle. The rectangle’s area is 12x16=192. For the triangle, you have to find the length of the b side. You already know a and c so 12^2 + b^2=15.5^2. Solve it algebraically to get b=9. So the triangle has an area of (12x9)/2=54. So the total area is 192+54=246cm^2.

A giant tortoise travels at 0.17 miles per hour and an arctic hare travels at 37 miles per hour. If
The tortoise and the hare start out together and after half an hour the hare stops to take a rest. How long does it take the tortoise to catch up

Answers

Answer:

3.145 Hours

Step-by-step explanation:

37÷2=18.5

18.5×.17=3.145

It will take the tortoise to catch up with the hare 109 hours.

Given that,
A giant tortoise travels at 0.17 miles per hour and an arctic hare travels at 37 miles per hour. If The tortoise and the hare start out together and after half an hour the hare stops to take a rest. How long it takes the tortoise to catch up is to be determined.

What is speed?

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,
Distance traveled by hare in half hour,
= speed * time
= 37 * 1/2
= 18.5 miles

Time is taken by the tortoise to catch up with the hare,
= distance / speed
= 18.5 / 0.17
≈ 109 hours

Thus, it will take the tortoise to catch up with the hare 109 hours.

Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?

Answers

Answer:

637, 245

Step-by-step explanation:

Speed is the rate of change in the position of an object. The distance between the two snakes after 10 mins is 15 inches.

What is the relation between speed, distance, and Time?

We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,

[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]

Given to us

Two snakes race The speed of the first is 24 1/2 inches per minute The speed of the other is 26 inches per minute

What is the distance between them after 3 mins?

The relative speed between them, as they are moving in the same direction, therefore,

Relative speed = (26-24.5) = 1.5 inches per minute

[tex]\text{Distance between them after 3 mins}= \rm speed \times \rm time[/tex]

                                                        [tex]= 1.5 \times 3\ mins\\= 4.5\ inches[/tex]

Thus, the distance between the two snakes after 3 mins is 4.5 inches.

What is the distance between them after 10 mins?

The relative speed between them, as they are moving in the same direction, therefore,

Relative speed = (26-24.5) = 1.5 inches per minute

[tex]\text{Distance between them after 10 mins}= \rm speed \times \rm time[/tex]

                                                          [tex]= 1.5 \times 10\ mins\\= 15\ inches[/tex]

Thus, the distance between the two snakes after 10 mins is 15 inches.
