Answer:

3.78 yd

Step-by-step explanation:

Rectangle area = length x width

a = (w+10)*w = w² + 10w = 52

w² + 10w - 52 = 0

w = (-10 ± √10²-4*1*(-52)) / 2 = (-10 ± √308)/2 = (-10 ± 17.55)/2

width must be positive: w = (-10 + 17.55)/ 2 = 7.55/2 = 3.78

Answers

Answer:

[tex]P(Hits) = 0.70[/tex]

Step-by-step explanation:

Given

[tex]Throws = 120[/tex]

[tex]Hits = 84[/tex]

[tex]Miss = 36[/tex]

See attachment for result

Required

Determine the probability of hitting the target

This calculated using:

[tex]P(Hits) = \frac{n(Hits)}{n(Throws)}\\[/tex]

[tex]P(Hits) = \frac{84}{120}[/tex]

[tex]P(Hits) = 0.70[/tex]

Hence, the probability of hitting the target is 0.70

The equation h=60-4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain

Answers

Answer:

40m

Step-by-step explanation:

Complete question

The equations h = 60 - 4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain. How high is the water after 5 minutes.

To get the height of the water after 5minutes, we will find h at when m = 5

h = 60 -4 (5)

h = 60 - 20

h = 40m

Hence the water is 40m high after 5minutes

Step-by-step explanation:

The first step is to calculate the volume of the cubiod

= 36 × 6 × 23

= 4968

= 4968/3 ×2

= 1656×2

= 3312

Therefore the greatest number of cups can be calculated as follows

= 3312/275

= 12

Hence the greatest number of cups is 12 cups
