144.44 in² is the closest amount of paper she will use to wrap the gift.

Solution:

The given net is the shape of the cylinder.

Diameter of the circle = 4 in

Radius of the circle = 4 ÷ 2 = 2 in

Width of the container = 10.5 in

Length of the container is same as the circumference of the circle.

Area of the circle = \pi r^2

                             = 3.14\times 2^2

                             = 12.56 in²

Area of the 2 circles = 2 × 12.56 = 25.12 in²

Area of the rectangle = circumference × height

                                    = 2 \pi r\times h

                                    = 2 \times 3.14 \times 2\times 10.5

                                    = 131.88 in²

Area of the net of the container

                                   = Area of the circles + Area of the rectangle

                                   = 12.56 in² + 131.88 in²

                                   = 144.44 in²

Area of the net of the container =  144.44 in²

Hence  144.44 in² is the closest amount of paper she will use to wrap the gift.

Two pumps connected in parallel fail independently of one another on any given day. The probability that only the older pump wil
Bogdan [553]

Answer : Probability that the pumping system will fail on any given day = 0.005

Explanation:

Probability that only older pump fail = P(A) = 0.10

Probability that only newer pump fail = P(B) = 0.05

Since they are independent events ,

then the conditions will be

P(A∩B) = P(A). P(B)

             = 0.10 ×0.05

             =  0.005

Hence, the probability will fail on any given day = 0.005

If 75% of budget is 1200, what is the full budget using a table?
Alisiya [41]

Answer: full budget of 100% will be 1600

Step-by-step explanation:

If 75% = 1200

Full budget will be 100%

Represent the question as if 75% = 1200

Then 100% = x

Cross multiply:

75%x = 1200%

Divide both sides by 75%

x = 1200%/75%

x = 16 × 100

= 1600

How are discontinuities and zeros created in rational expressions, and in what ways can they be accounted for graphically?
pshichka [43]

Discontinuities can be recognized by observing at asymptotes. An asymptote is a line where the space between the curve and the line go to zero as single or both of the x or y coordinates inclines to infinity. Graphically, they're holes in the graph. Zeroes are points wherever the graph hits the x axis.
