Angle 5 is 90 and because all the angles should add to 360 degrees, angle 4 is 20, and angles 3 and 6 are 70 and 70. 90+90+20+20+70+70= 360

A basketball court is 94 feet by 50 feet. To sketch the court on paper a scale factor of 1 foot to 16 feet is applied. What is t

Eddi Din [679]

Based on the dimensions of the basketball court, we can calculate that the area of the scaled copy is<u> 18 ²³/₆₄ feet².</u>

<h3>Dimensions of scaled copy</h3>

Every 16 feet of the actual court is 1 foot on the scaled copy. The dimensions of the scaled copy are therefore:

= 94 / 16 = 50 / 16

= 5.875 feet = 3.125 feet

<h3>Area of scaled copy </h3>

= Length x Width

= 5.875 x 3.125

= 18.359375

= 18 ²³/₆₄ feet²

In conclusion, the area is 18 ²³/₆₄ feet².

Phil can paint the garage in 12 hours and Rick can o it in 10 hours. If they work together for 3 hours and then Phil leaves, how

daser333 [38]

Answer:

It will take 4.5 hours for rick to complete the job.

Step-by-step explanation:

Given:

Time taken by Phil to paint the garage = 12 hours.

It means that for each hour he does = $\frac{1}{12}$ of the job.

Time taken by Rick to paint the garage = 10 hours.

It means that for each hour he does = $\frac{1}{10}$ of the job

If they work together for 3 hours,

Phil does job in 3 hrs = $3\times\frac{1}{12} = \frac{1}{4}=0.25$

Rick does job in 3 hrs = $3\times\frac{1}{10} = \frac{3}{10}=0.3$

So in three hours of working together job done = $0.3+0.25 = 0.55$

This means job of the painting entire garage have been done 0.55 of it.

1 - 0.55 = 0.45.

So there is 0.45 job left

At this point Phil quits and Rick presses on by himself. Since he does 1/10 of the garage every hour

Let T represents the time that Rick needs to complete the job after Phil leaves.

Hence, $\frac{1}{10}\times T= 0.45\\\\T = 0.45 \times 10\\T =4.5 hrs$

Hence it will take rick 4.5 hours to complete the remaining job.

g On any day, the probability of rain is 0.3. The occurrence of rain on any day is independent of the occurrence of rain on any

Ksju [112]

Answer:

0.249579

Step-by-step explanation:

P(rain) = 0.3

P(no rain) = 1 - 0.3 = 0.7

The event of rain falling a second time within the next 5 days is possible in these ways

1. Rain on days 1 and 2

2. Rain on days 1 and 3; none on day 2

3. Rain on days 1 and 4; none on days 2 and 3

4. Rain on days 1 and 5; none on days 2, 3 and 4

5. Rain on days 1 and 6; none on day 2, 3, 4 and 5

$P(\text{second rain within 5 days}) = 0.3^2+0.3^2\times0.7+0.3^2\times0.7^2+0.3^2\times0.7^3+0.3^2\times0.7^4 = 0.3^2(1+0.7+0.7^2+0.7^3+0.7^4)= 0.09\times2.7731=0.249579$
