Answer:
(a) = 11 cm
Step-by-step explanation:
The formula for finding the surface area of a regular pyramid is B + (1/2*P*l), with B being the area of the base, p being the perimeter of the base, and l being the slant of the pyramid.
The area of a pentagon can be solved using the formula 1/2*a*p, with a being the apothem and p being the perimeter of the pentagon.
- B + (1/2*80*15) = 1040
- B + 600 = 1040
- 1040 - 600 = 440 (440 is the area of pentagon)
- 1/2*a*(16*5) = 440
- 40*a = 440
- 440/40 = 11
The apothem is 11 cm. Hope this helps!
Answer:
6 units
Step-by-step explanation:
This coordinate is a three dimensional coordinate, which involves positive and negative x,y, and z axis.
The y axis is from left to right, i.e from negative to positive.
So 6 unit left is = -6 but it explains moving left .
Thank you

Answer:
20 days
Step-by-step explanation:
The number of days will be a multiple of both 4 and 5. The smallest such multiple is called the "least common multiple" (LCM). One way to figure the LCM is to divide the product of the numbers by their greatest common factor. Since 4 and 5 have no common factors, the LCM is 4·5 = 20.
Both teams will be practicing on the same day again in 20 days.
Answer:
x+ x×3%×11/2=19513.75 considering 3% interest per year for 5 and a half years
x=8375
Step-by-step explanation:
x×233/200=19513.75
x=1951375/233
x=8375
