Answer:
D. 88
Step-by-step explanation:
if you add the given numbers up (equals 100) them subtract it from 540(the degrees of a Pentagon) you get 440. then divide that by 5 (number of xs left) you get 88. You can plug in 88 for x and check but I already did, I hope this helps you lemme know if it does :)
The estimate would be 1200.
We will set up a proportion for this. 10 out of 60 of the sample were tagged, so that is the first ratio. The 200 that were tagged would be in the numerator of the second ratio (10 was the portion tagged, and 200 is the portion tagged, so they both go on top). We do not know the total number so we use a variable:
10/60 = x/200
Cross multiply:
10*x = 60*200
10x = 12000
Divide both sides by 10:
10x/10 = 12000/10
x = 1200

Answer:
The diameter of the circle is 56 cm.
Step-by-step explanation:
Given : The area of the circle is 2464 cm square.
To find : The diameter of the circle?
Solution :
The area of the circle is defined as
Where, A=2464 cm² is the area,
r is the radius
Substituting the values,
Radius of the circle is 28 cm.
The diameter of the circle is
Therefore, The diameter of the circle is 56 cm.
Answer:
, a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.
