Mathematics
1 answer:
olga_2 [115]2 years ago
8 0

Answer:

The answer is below

Step-by-step explanation:

a)

The area of the figure = sum of the area of the individual polygons

The area of the figure = x + 1 + y + 1 + x = 2x + y  + 2

The perimeter of the figure = sum of the length of the sides = 2(1 + (x + 1 + y + 1 + x)) = 2(2x + y + 3) = 4x + 2y + 6

b)

a)

The area of the figure = sum of the area of the individual polygons

The area of the figure = y² + xy + 1 + 1 + 1 = y² + xy + 3

The perimeter of the figure = sum of the length of the sides = (y + 1) + x + y + (y + 1) + y + 1 + 1 + 1 + x + 1 = 4y + 2x + 6

There are 206 bones in the body. What fraction represents the number of bones in one hand (27) compared to the total number of b
Law Incorporation [45]

Answer:

\frac{27}{206}

Step-by-step explanation:

Let

x -----> the number of bones in one hand

y -----> the total number of bones in the body

we know that

The fraction that represents the number of bones in one hand compared to the total number of bones in the body, is equal to divide the number of bones in one hand by the total number of bones in the body,

we have

x=27\ bones\\y=206\ bones

\frac{x}{y} =\frac{27}{206}

The 10,000-meter long-distance running event in the summer Olympics is approximately 6.2 miles. Which equation could be used to
Dima020 [189]

Answer:

t = 6.2/s miles/minute

Step-by-step explanation:

Average speed is defined as the rate of change in distance of a body. Mathematically; speed = Distance/Time

Given the distance of the runner in miles to be d = 6.2miles

Time taken = t

Average speed = s

To express t in terms of the average speed s and distance of 6.2miles, we will substitute the values into the formula;

s = D/t

Substituting D = 6.2miles into the formula;

s = 6.2/t

Cross multiply

St = 6.2

Divide both sides by 's'

st/s = 6.2/s

t = 6.2/s

Hence, the equation that could be used to determine the time, t, it takes to run 10,000 meters as a function of the average speed, s, of the runner where t is in minutes and s in miles per minute is t = 6.2/s miles/minute
