Answer: Ashley had more yarn, 1 yard = 3 ft 3 times 4 = 12 so 3 yards is 12 feet.
Step-by-step explanation:
Answer:
x=70
Step-by-step explanation:
Angle 1 will be 90° when it subtends a 180° arc. That means the sum of 100° and (x+10) must be 180°, so (x+10) = 80°.
We assume this is intended to mean ...
... (x +10)° = 80° . . . . . note the ° symbol added outside parentheses
... x +10 = 80 . . . . . divide by °
... x = 70 . . . . . . . . .subtract 10
_____
If the intent is (x+10°) = 80°, then x=70°.

<em>Comment on the numbers here</em>
Units need to be properly specified in problems of this nature. <em>As written</em>, we probably should assume that 10 is <em>radians</em>, and x is a large negative number, about -8.60374 (radians), or -492.958°.
A number of radians is a "pure number." It has <em>no units</em>. The term "radians" is used to signify that the number is considered to be an angle measure.
So 5x=30
then x= 30/5
and x=6
so the answer is last one !
Answer:
Radius is 5 units
Step-by-step explanation:
The radius of a circle will always be 1/2 of the diameter.
This gives the formula:
(substitute known values)
(divide 10 by 2)
Therefore the radius is five
Answer:
Step-by-step explanation:
x/4 - y/3 = 1..multiply everything by the LCD....which is 12
3x - 4y = 12 <== standard form
=====================================
if it makes it easier for u, x/4 is the same as (1/4)x and y/3 is the same as (1/3)y
so ur problem can be written as : (1/4)x - (1/3)y = 1....multiply by 12
12(1/4)x - 12(1/3)y = 12(1)
(12/4)x - (12/3)y = 12.....reduce
3x - 4y = 12
