What is the value of n?
sineoko [7]
A. 69 degrees

exterior angles should equal 360 degrees so just add 131+160= 291 , 360-291= 69 degrees

or u can find it by finding the interior angle degrees by using supplementary angles. 180-131= 49 , 180-160= 20, 20+49=69, 180-69= 111 so the missing exterior angle corresponding interior is 111 and u can use supplementary angles to find the exterior. 180-111= 69 degrees

Vivian approximated the value of the cube root of 1010 to be 10.0. William claimed that 10.1 is a closer approximation. Whose ap
Luda [366]

ANSWER

10.0 ------- Vivian is correct

EXPLANATION

Firstly, find the cube root of 1010

\sqrt[3]{1010\text{ }}\text{ = 10.033}

In the above calculation, the cube root of 1010 is 10.003

The correct approximation of the above value is 10.0. This is because the hundredth value is not upto 5

Recall, figures from 1 - 4 are rounded to zero and figures from 5- 9 are rounded up to 1

since 3 is not upto 5, so it is rounded down to zero

Therefore, Vivian is correct

How do you solve the system of linear equations for this problem: (2.1x+4.2y=14.7) & (-5.7x-1.9y=-11.4)
Alenkinab [10]
2.1x + 4.2y = 14.7 is the same as x + 2y = 7 (divide both sides by 2.1)
-5.7x-1.9y=-11.4 is the same as 3x + y = 6 (divide both sides by -1.9)

Rearrange the first equation to get x = 7 - 2y and substitute into the second equation, 3(7 - 2y) + y = 6, 21 - 6y + y = 6, 5y = 15, y = 3

Substitute y = 3 into the first equation x + 2(3) = 7, x = 1

x = 1 and y = 3
