Answer: 0.8 or 80%
Step-by-step explanation:
First find the total number of marbles:
10 + 15 + 25 = 50 marbles total
To find the number of marbles that are not black:
15 + 25 = 40 marbles that are not black
Set up ratio:
= 0.8 or 80%
Answer:
20 +4√2
Step-by-step explanation:
Find the total area the regular pyramid = A + 1/2ps
A is the Base area
p is the perimeter of the base
s is slant height
A = 1/2 * 4 * 4
A = 16/2
A = 8
p = 4 + 4 + (√4^2+4^2)
p = 8 + √32
p = 8 + 4√2
s = 4
Substitute
TSA = 8 + 8 + 4√2 + 4
TSA = 20 +4√2
Hence the total surface area is 20 +4√2
1. -1/20
work: Write all numerators above the least common denominator: -8+2+5/20
*Calculate the sum or difference: -1/20

<span>the total number of sit ups = 7(60 + 5)
= 7 * 60 + 7 * 5
= 420 + 35
= 455
