Answer:
<h3><u>4</u></h3>
Step-by-step explanation:
We know that,
![cos \alpha = \frac{side \: adjacent \: to \: \alpha }{hypotenuse} \\](https://tex.z-dn.net/?f=cos%20%20%5Calpha%20%20%3D%20%20%5Cfrac%7Bside%20%5C%3A%20adjacent%20%5C%3A%20to%20%5C%3A%20%20%5Calpha%20%7D%7Bhypotenuse%7D%20%20%5C%5C%20)
<h3>Therefore, from the figure:-</h3>
cos60° = BC/ AC
=> 1/2 = 2/x
=> x = 4
Answer:
the answer is zero for people using apex
Step-by-step explanation:
We let x and y be the number of Hobbies & Recreation and Soliloquies episodes that Steve subscribe. The system of linear equation that best represent the given above is,
x + y = 10
32x + 42y = 340
The values of x and y from the system are 8 and 2, respectively. Thus Steve subscribed to 8 Hobbies & Recreation and to 2 Soliloquies episodes.
Answer:
Option D. A circles area and circumference are only equal when the radius is 2 units.
Step-by-step explanation:
we know that
The area of circle is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
The circumference of a circle is equal to
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
equate both formulas
![\pi r^{2}=2\pi r](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D%3D2%5Cpi%20r)
simplify
![r^2=2r\\r=2](https://tex.z-dn.net/?f=r%5E2%3D2r%5C%5Cr%3D2)
therefore
A circles area and circumference are only equal when the radius is 2 units.
Answer:
11:10
Step-by-step explanation:
1h15m + 40m + 25m + 30m = 2h50m
She'd need to start 2h50m before 2:00, which would be 11:10 I think
