4/5 divided by 7/10 is equal to 8/7.

We have

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of a fraction is obtained by flipping it, which means swapping the numerator and the denominator.

So, to divide 4/5 by 7/10, we multiply 4/5 by the reciprocal of 7/10.

Reciprocal of 7/10 = 10/7

Now we can multiply:

(4/5) x (10/7)

Multiplying the numerators and denominators gives us:

(4 x 10) / (5 x 7) = 40/35

To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 5:

40/35 = (40 ÷ 5) / (35 ÷ 5) = 8/7

Therefore,

4/5 divided by 7/10 is equal to 8/7.

Answer:

25.6 units

Step-by-step explanation: From the figure we can infer that our triangle has vertices A = (-5, 4), B = (1, 4), and C = (3, -4).

First thing we are doing is find the lengths of AB, BC, and AC using the distance formula:

d=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}

where

(x_1,y_1) are the coordinates of the first point

(x_2,y_2) are the coordinates of the second point

- For AB:

d=\sqrt{[1-(-5)]^{2}+(4-4)^2}

d=\sqrt{(1+5)^{2}+(0)^2}

d=\sqrt{(6)^{2}}

d=6

- For BC:

d=\sqrt{(3-1)^{2} +(-4-4)^{2}}

d=\sqrt{(2)^{2} +(-8)^{2}}

d=\sqrt{4+64}

d=\sqrt{68}

d=8.24

- For AC:

d=\sqrt{[3-(-5)]^{2} +(-4-4)^{2}}

d=\sqrt{(3+5)^{2} +(-8)^{2}}

d=\sqrt{(8)^{2} +64}

d=\sqrt{64+64}

d=\sqrt{128}

d=11.31

Next, now that we have our lengths, we can add them to find the perimeter of our triangle:

p=AB+BC+AC

p=6+8.24+11.31

p=25.55

p=25.6

We can conclude that the perimeter of the triangle shown in the figure is 25.6 units.
