Answer:
C = 60t + 70
Step-by-step explanation:
The total cost of hiring Plumbing Service is given by the equation C = 50t + 70, where C is the total cost in dollar and t is the time in hours.
So, $ 70 is the fixed price and $50 is the rate of charge per hour for the service.
Now if in the next month the rate of charge per hour for the service increased to $60 and the initial charge remains the same then the equation for the total cost of hiring Plumbing Service will become C = 60t + 70. (Answer)
A polygon that has both reflectional and rotational symmetry includes:
- B. Square
- C. Triangle
- E. Equilateral Triangle.
<h3>What is a polygon?</h3>
A polygon is a closed curve made up of a set of line segments (sides) connected in such a way that no two segments cross.
Examples of polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides).
Triangle, square, and other quadrilaterals have both line symmetry and rotational symmetry.
Thus, a polygon that has both reflectional and rotational symmetry includes Options B, C, and E.

Answer:
Step-by-step explanation:
Here the region between two curves is rotated about a vertical line.
The functions are
![y = sin^2x, \\y = sin^4x, \\x in [0,[pi]/2].](https://tex.z-dn.net/?f=y%20%3D%20sin%5E2x%2C%20%5C%5Cy%20%3D%20sin%5E4x%2C%20%5C%5Cx%20in%20%5B0%2C%5Bpi%5D%2F2%5D.)
Intersecting points are x=0 and x =pi/2
Since rotated about x = pi/2 we get
using cylindrical shell method

Answer:
She can only use one gigabite.
Step-by-step explanation:
Total=shirtcost+tax
shirtcost=100%
8.5%+100%=108.5%=1.085
1.085 times 25.99=28.19915
round
total cost is
$28.20
