Answer:

112 = 4.5p + 40

subtract 40 from both sides

72 = 4.5p

divide by 4.5 on both sides to get 'p' by itself

16 = p

this means that Roger must make 16 pairs of shoes in order to meet his daily earnings goal of $112

A bakery sold 36 brownies in a day, which was 30% of the total items sold that day. What was the total number of items the baker
babymother [125]

Answer:

120

Step-by-step explanation:

We know that 36 is 30% of total items

So our equation would be 36/? = 30/100

From there we cross multiply so 36x100 = 3600

From there, we divide 3600 by 100

Therefore, your answer is 120

You and a friend want to know how much rope you need to climb a large rock. your friend is 5.5 feet tall and casts a shadow that
Neko [114]
The concept useful in finding the answer to this item is ratio and proportion, the ratio of the height of your friend with the shadow casted should be proportional to the height of the rock with the length of the shadow it cast. That is,
                       5.5 ft / 18 ft = x ft/ 209.5 ft
The value of x from the equation above is 64 ft.

A) Find the area<br>B) Find the perimeter ​
Archy [21]

Answer:

A)

A1= 64

A2= 40

B)

P= 56(of whole shape)

Step-by-step explanation:

A squares area is a side squared so 8^2= 64, and it is also shown that a side of the square is the base of the parallelogram. The area of a parallelogram is b*h so (square side)(8) * height(5)= 40.

Since a parallelograms opposite sides are congruent, 8+8=16, and the other two sides need to be congruent and equal to 40-16(24), therefore the sides are both 12.

Then to calculate the perimeter just count up the side lengths, 8+8+8+12+8+12=56

The weights of adult male birds of a certain species are normally distributed with a mean of 27.5 grams and a standard deviation
Korvikt [17]

Answer:

The z-score of a male bird of this species with a weight of 29.37 grams is 1.7.

Step-by-step explanation:

We are given that the weights of adult male birds of a certain species are normally distributed with a mean of 27.5 grams and a standard deviation of 1.1 grams.

<u><em>Let X = weights of adult male birds of a certain species</em></u>

So, X ~ Normal(\mu=27.5,\sigma^{2} =1.1^{2})

The z score probability distribution for normal distribution is given by;

                                 Z = \frac{ X-\mu}{\sigma } }  ~ N(0,1)

where, \mu = population mean weight = 27.5 grams

           \sigma = standard deviation = 1.1 grams

The Z-score measures how many standard deviations the measure is away from the mean. After finding the Z-score, we look at the z-score table and find the p-value (area) associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.

SO, the z-score of a male bird of this species with a weight of 29.37 grams is given by;

          <u>Z score</u> =  \frac{ X-\mu}{\sigma } } = \frac{ 29.37-27.5}{1.1 } }

                                    =  <u>1.7</u>
