Answer:
area is 630
we can multiply 2 1 by 21= 63 by 10=630
8.75 x 37.5= ? Well all you do is have to line up the decimals and work it out! :) it's simple
Answer:
Step-by-step explanation:
Given that transitor has a 2% defective rate, need to calculate the probability that the 10th transistor produced is the first with a defect.
The probability function is p(x=k) = (1-p)^(n-1) * p
p = (1-defective rate)^(n-1) * defective rate; n=10
p = (1-0.02)^9 * 0.02 = 0.98^9 * 0.02 = 0.01666
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:
There were 12 + 28 = 40 pieces of fruit in the basket.
Step-by-step explanation:
Suppose there were x oranges and y grapefruit.
Then we have
1 /3 x = 4
x = 4*3 = 12.
1/4 y = 7
y = 7*4 = 28.
