An easier way to do this is to make the fractions improper fractions.
3 1/6 can be rewritten as 19/6. 1 4/6 can be rewritten as 10/6. (Multiply the denominator by the number at its side, and add it to the numerator).
2 3/6 is 15/6.
Subtract 10/6 from 19/6.
19/6-10/6=9/6.
9/6 is not 15/6, therefore she did not use 2 3/6 yards of fabric.
Answer:
4³
Step-by-step explanation:
{(2)²}⁷/{(2)²}¹⁰
2¹⁴/ 2²⁰
Using property...
2¹⁴-²⁰= 2-⁶
Hence....
(-2)×(-2)×(-2)×(-2)×(-2)×(-2)= 64
So...
64=4³
hope it helps
Answer:
The solution of the system of linear equations is and .
Step-by-step explanation:
Let and expressions of the system of linear equations. Since the number of variables and equations are the same, there is only one solution and we can solve it by algebraic means:
(1)
(2)
From (1):
By applying (1) in (2):
By (1):
The solution of the system of linear equations is and .
Answer:
Length of the chord: 24 units
Angles are equal
Step-by-step explanation:
Drop a Perpendicular from the centre onto the chord. It will divide the chord into two equal parts, d units each
d² + 16² = r²
d² = 20² - 16²
d² = 144
d = 12
Chord = 2d = 24 units
Measure of central angle and the corresponding chord related to the measure of the arc intercepted by the chord are the same, they're equal
