D. A ray has one endpoint.
Answer:
1. 8820.26 yds^2
2. 101.265 m^2
Step-by-step explanation:
For both problems you need to use the equation π*r^2 which is the area of a circle and where r is the radius of the circle. The radius is also equal to 1/2 the diameter so using this we can figure out the are of the first circle
For the second problem we have to find the area of the circle with and without the sidewalk around it and subtract them from each other
The slope of the equation is 1/2.
Part 2) <span>What is the surface area of this cube?
we know that
surface area of a cube=6*b</span>²
where b is the length side of a cube
in this problem
b=15 mm
so
surface area of a cube=6*15²----> 1350 mm²
the answer Part 2) is 1350 mm²
Part 3) What is the surface area of this cube?
we know that
surface area of a cube=6*b²
where b is the length side of a cube
in this problem
b=11 cm
so
surface area of a cube=6*11²----> 726 cm²
the answer Part 3) is 726 cm²
part 4) <span>What is the surface area of the rectangular prism represented by the net?
surface area=2*16*6+2*16*8+2*6*8----> 544 cm</span>²
the answer Part 4) is 544 cm²
Part 5) <span>What is the surface area of the wood block?
surface area=5*5+4*[5*8]/2----> 25+80----> 105 in</span>²
the answer part 5) is 105 in²
Answer:
4.4 hours
Step-by-step explanation:
Let the number of hours = x
Ida needs to hire a singer for her wedding.
For Singer A
Singer A is offering his services for an initial $65 in addition to $13.15 per hour.
65 + 13.15x
Singer B
Singer B is offering her services for an initial $73 in addition to $11.35 per hour.
73 + 11.35x
We equate both singers together
Singer A = Singer B
65 + 13.15x = 73 + 11.35x
We collect like terms
13.15x - 11.35x = 73 - 65
1.8x = 8
x = 8/1.8
x = 4.4444444444 hours
Approximately = 4.4 hours
The two singers will charge the same amount of money after 4.4 hours
