2. Subtract these fractions, then simplify.7/10 - 1/2 = O 4/5 O 3/5 O 1/5

1/5 or 0.2 & 0/5 or 0

Step-by-step explanation:

7/10 - 1/5 = ?

0.7 - 0.2 = 0.5

4/5 - 3/5 - 1/5 = ?

0.8 - 0.6 - 0.2 = 0

Side Note:

I am having trouble understanding the use of O's. Please elaborate for a clearer answer.

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
