Answer:
Step-by-step explanation:
B 10/12 = 6/7.2 = 8/9.6 = 5/6
Answer:
The anwser is C: 6/5
Step-by-step explanation:
12 divided by 10 = 1.2 = 6/5
9.6 divided by 8 = 1.2 = 6/5
7.2 divided by 6 = 1.2 = 6/5
The lengths of two sides of a right angled triangle are 20 cm and 30 cm.
Calculate the length of the third side, if it is:
(a) the hypotenuse
(b) not the hypotenuse
Answers
Answers:
Part (a) 10*sqrt(13) Part (b) 10*sqrt(5)Those values are exact. They approximate to:
10*sqrt(13) = 36.0555
10*sqrt(5) = 22.3607
====================================================
Explanation:
Part (a)
If the unknown third side is the hypotenuse then we need to find the value of c when a = 20 and b = 30.
Apply the pythagorean theorem
a^2 + b^2 = c^2
20^2 + 30^2 = c^2
400 + 900 = c^2
1300 = c^2
c^2 = 1300
c = sqrt(1300)
c = sqrt(100*13)
c = sqrt(100)*sqrt(13)
c = 10*sqrt(13) .... exact length
c = 36.0555 ...... approximate length
------------------------------------
Part (b)
If the third side is not the hypotenuse then that must mean c = 30 is the hypotenuse as this side is larger than the 20 cm side. The hypotenuse is always the longest side.
Let a = 20 be the known leg. Let's find the other unknown leg b using the pythagorean theorem.
a^2 + b^2 = c^2
20^2 + b^2 = 30^2
400 + b^2 = 900
b^2 = 900-400
b^2 = 500
b = sqrt(500)
b = sqrt(100*5)
b = sqrt(100)*sqrt(5)
b = 10*sqrt(5) ..... exact length
b = 22.3607 ....... approximate length

20 fans at a 49ers game are asked what their favorite team is.
Answers
Answer:
4) Unbiased; 5) Biased
Step-by-step explanation:
4) states that the audience of the poll was "random" people meaning it's a good foundation of data as they weren't chosen for the employee noticing their specific affiliation with being overjoyed with the product (as the question doesn't say) or for not liking (have complaints about it) the product.
5) The audience of the poll is fans of a sports team--definitely biased because they'll say they love the 49ers being a fan for them. Leads to skewed results not representing a portion of a population accurately.

Write a function rule for "The output is two more than one-fourth of the input ."
Answers
Answer:
y=(x/4)+2
Step-by-step explanation:
let y be the output and x be the input. So,
y=(x/4)+2
The function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.
What is function?A function is a relation between a dependent and independent variable. We can write the example of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is to find the function rule for "The output is two more than one-fourth of the input."
The given mathematical statement is - "The output is two more than one-fourth of the input."
Assume the input to be {x} and the output be {y}. So, we can write that -
(output) = (two) + (1/4)(input)
y = 2 + (1/4)x
Therefore, the function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.

What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
It takes the Sun about 2.3x10⁸ years to orbit the center of the Milky Way.
It takes Pluto about 2.5 times 10 squared years to orbit the Sun.
Pluto orbits the Sun while the Sun completes one orbit around the Milky Way,
= 2.3 x 10⁸ x (2.5 x 10)²
= 14.375 x 10¹⁰
Therefore, the required time is 14.375 x 10¹⁰ years.

Find the value of x:
Answers
Answer:
x = 3
Step-by-step explanation:
These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:
(10x + 1) = (12x - 5)
Add 5 on both sides:
10x + 6 = 12x
Subtract 10x on both sides:
6 = 2x
Divide 2 on both sides:
3 = x
Answer:
(10x+1)°=(12x-5)°. [vertically opposite angle]
1+5=12x-10x
6= 2x
3=x
therefore,x=3
