A red ant travels 9/8 inches in 3/4 minutes and 3 3/8 inches in 2 1/4 minutes what is the ants speed in inches per minute? What

I am Lyosha [343]

Answer:

1. 1.5 inches per minute

2. 90 inches per hour

Step-by-step explanation:

speed = $\frac{distance}{time}$

1. total distance covered = $\frac{9}{8}$ + $\frac{27}{8}$

= $\frac{9+27}{8}$

= $\frac{36}{8}$

= 4 $\frac{1}{2}$ inches

Total time taken = $\frac{3}{4}$ + $\frac{9}{4}$

= $\frac{3 +9}{4}$

= $\frac{12}{4}$

= 3 minutes

The ants average speed = $\frac{4.5}{3}$

= 1 $\frac{1}{2}$

= 1.5

The ants speed is 1 $\frac{1}{2}$ inches per minute.

2. Since;

60 minutes = 1 hour

3 minutes = x hours

x = $\frac{3}{60}$

= $\frac{1}{60}$

= 0.05 hours

Speed = $\frac{4.5}{0.05}$

= 90 inches per hour

The red ants speed is 90 inches per hour.

It’s not supplementary does anyone know what it is?

Mrac [35]

I agree with your answer "supplementary". The two angles combine to form 180 degrees, aka a straight angle

-1/2(x-6)-1/4(x-4)=x-7

pentagon [3]

-1/2(x-6)-1/4(x-4)-(x-7)= ?

Simplify 1/4
1 ÷ 4 = 0.25

Simplify 1/2
1÷2 = 0.5

The lowest common denominator of this problem is 4

16 - 3(x) / 4 - ( x - 7)

44 - 7(x) / 4

-7(x)+44 = 0

-7 - 44 = -51

-7 - 0 = -7

-7(x) = 44

-7(-1)(x) = x

-1(44) = -44

44 ÷ 7 = 6.28

We have have one solution in this problem

So, therefore x = 44/7
