1)four congruent circular holes with a diameter of 2in were punched out of a piece of paper,what is the area of the paper that i
Vesna [10]
For this case we first calculate the area of the complete rectangle.
 We have then:
 A1 = (8.5) * (11)
 A1 = 93.5
 Then, we calculate the area of each circle:
 A2 = pi * r ^ 2
 A2 = (3.14) * (2/2) ^ 2
 A2 = 3.14
 The total area is given by:
 A = A1 - 4 * A2
 A = 93.5 - 4 * (3.14)
 A = 80.94 in ^ 2
 Answer:
 
A) 80.94

Nadya [2.5K]

Answer:

144 people were originally at the party.

Step-by-step explanation:

18 boys is one fifth of the second boys population, so the second population is 18x9 = 162. The original population would be 162-18, which equals 144.

Fill in the blank space<br> z2 + 5z – 36 = (z – 4)(z +_)
labwork [276]
Answer=9

To solve this, we just have to find a number that, when added to -4, make a total of 5, and when multiplied by -4 make a total of -36.

x+-4=5

x*-4=-36

9 fits the parameters for both of these

9+-4=9
9-4=5
5=5

9*-4=36
36=36
