Answer:

648 cups, 3 fluid ounces

Step-by-step explanation:

You need to know that 1 cup = 8 fluid ounces (fl. oz).

convert to fl. oz:

1296 cups = 10368 fl.oz.

total fl.oz. = 10368+6 = 10374

10374 / 2 = 5187 fl.oz.

= 648 cups and 3 fluid ounces

Answer:

12/20

Step-by-step explanation:

Cosine is a trigonometric identity. It is a ratio of the adjacent side and hypotenuse of a right triangle.

The adjacent side to angle Θ is 12. The hypotenuse of this triangle is 20.

cosΘ in this case would be 12/20.

You wash dishes for a chemistry laboratory to make extra money for laundry. You earn 12 dollars/hour, and each shift lasts 75 minutes. Your laundry requires 12 quarters/load.Part AHow many shifts must you work if you wish to wash 10 loads of laundry

Answers

Answer:

2 shifts

Step-by-step explanation:

Amount earned washes dishes = 12 dollars / hour

Shift duration = 75 minutes

Cost of laundry = 12 quarters per load

Cost of 10 loads of laundry = (10 * 12 quarters) = 120 quarters

1 quarter = 25 cents

120 quarters = (25 * 120) = 3000 cents

100 cents = $1

3000 cents = 3000/ 100 = $30

Hence, to make $30 from washing dishes :

$12 = 1 hour

$30 = x

x = 30 / 12

x = 2.5 hours

1 shift lasts 75 minutes

2.5 hours = (2.5 * 60) = 150 minutes

150 / 75 = 2 shifts

A biologist studied the frequency of croaks for frogs from two different regions. From a random sample of 32 frogs located in the northern region, the mean number of croaks per hour was 21.3, and from a random sample of 38 frogs located in the southern region, the mean number of croaks per hour was 28.9. To estimate the difference in the mean number of croaks (southern minus northern), a 95 percent confidence interval was constructed from the samples. The interval was reported as (7.1, 8.1). Which of the following claims is supported by the interval?
A. All southern frogs croak more times per hour than do all northern frogs.
B. The northern frogs are likely to have a greater mean number of croaks per hour than the southern frogs.
C. The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.
D. All frogs in the study have about the same number of croaks per hour.
E. The northern and southern frogs have the same mean number of croaks per hour.

Answers

Answer:

C

Step-by-step explanation:

Since at the 95% confidence, the difference between the number of croaks per hour between southern and northern region frog is lying in the rage 7.1 to 8.1, this shows that the southern region's frogs' croak frequency is highly likely to be greater than that of northern region's frogs' croaks' frequency.

The claim supported by the interval is

Option C. The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.

What does the interval tell obtained in the hypothesis testing?

The interval we obtain at certain confidence tells that the value of the test statistics will lie in that interval with that confidence.

How to identify what is the obtained interval indicating?

Since the test statistics was measuring the croak frequency difference

with southern - northern, and since at 95% confidence,  the difference will lie in interval (7.1, 8.1), which is positive, thus the frequency of crocks for southern frogs is greater than the frequency of crocks for northern frogs.

Thus,

The claim supported by the interval is

Option C. The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.

To be able to solve clearly this problem, the best thing to do is to plot the graph (see attached pic). From the graph we can see that the points form a trapezoid.

The base is formed by the segment connecting point A and point B.

While the two heights: shorter one by the segment connecting points A and D, and the longer one by the segment connecting points B and C.

The formula for area of trapezoid is given as:

A = b (h1 + h2) / 2

Where,

b = base of the trapezoid  = 3 – (-4) = 7

h1 = shorter height = 2 – (-2) = 4

h2 = longer height = 2 – (-5) = 7

Therefore the area is:

A = 7 (4 + 7) / 2

A = 77 / 2

A = 38.5

6. The length of a football field is 30 yards more than its width.
Express the length of the field in terms of its width. If the perimeter
of the field is 340 yards. find the width of the field. I

Answers

Answer:

the width be 70 yards

Step-by-step explanation:

The computation of the width of the field is as follows:

As we know that

The Perimeter of the rectangle is

= 2 × (length + width)

Where

Perimeter is 340 yards

Let us assume the width be x

So, the length would be x + 30

Now put these values to the above formula

340 = 2 × (x + x + 30)

340 = 2 × (2x + 30)

340 = 4x + 60

4x = 280

x = 70

The length would be

= 70 + 30

= 100

Hence, the width be 70 yards

A series of maths books consists of four volumes. The first has x pages and the second has 54 more. The third and fourth volumes have 32 more pages than the second volume. The number of pages of all volumes is 866. Calculate the number of pages in each volume.

Answers

Answer:

1st volume = 160

2nd volume = 160 + 54 = 214

3rd volume = 160 + 54 + 32 = 246

4th volume = x + 54 + 32 = 246

Step-by-step explanation:

Given that:

Number of volumes = 4

1st volume = x pages

2nd volume = 54 more = x + 54

3rd volume = 32 more = x + 54 + 32

4th volume = 32 more = x + 54 + 32

Total number of pages = 866

Hence,

1st + 2nd + 3rd + 4th = 866

x + x + 54 + x + 54 + 32 + x + 54 + 32 = 866

4x + 226 = 866

4x = 640

x = 160

1st volume = 160

2nd volume = 160 + 54 = 214

3rd volume = 160 + 54 + 32 = 246

4th volume = x + 54 + 32 = 246

What expression can be used to find the nth term in the sequence 5,7,9, 11,...?

2n - 3

n + 2

n - 3

2n + 3​

Answers

Answer:

The required expression which can be used to find the nth term in the sequence is:

[tex]a_n=2n+3[/tex]

Hence, the fourth option i.e. 2n+3 is the correct option.

Step-by-step explanation:

Given the sequence

5, 7, 9, 11,...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]7-5=2,\:\quad \:9-7=2,\:\quad \:11-9=2[/tex]

The difference between all the adjacent terms is the same and equal to

d = 2

So

a₁ = 5d = 2

Thus, the nth term of the sequence is

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substitute a₁ = 5 and d = 2 in the sequence

[tex]a_n=2\left(n-1\right)+5[/tex]

[tex]a_n=2n+3[/tex]

Therefore, the required expression which can be used to find the nth term in the sequence is:

[tex]a_n=2n+3[/tex]

Hence, the fourth option i.e. 2n+3 is the correct option.

Answer:

x = 67

Step-by-step explanation:

2x - 17 + 63 = 180 {Linear pair}

     2x + 46  = 180    

             2x = 180 - 46

             2x = 134

               x = 134/2

              x = 67

Solution :

[tex]\color{plum}\bold{x \tt \: = 67}[/tex]

Steps to derive the correct solution :

∠63° and ∠(2x-17)° are a linear pair, so their sum will be equal to 180°.

Which means :

[tex] = 63 + 2x - 17 = 180[/tex]

[tex] = 63 + 2x = 180 + 17[/tex]

[tex] = 63 + 2x = 197[/tex]

[tex] = 2x = 197 - 63[/tex]

[tex] = 2x = 134[/tex]

[tex] = x = 67[/tex]

Let us place 67 in the place of x and see if the substitution is equivalent to 180° :

[tex] = 63 + 2 \times 67 - 17 = 180[/tex]

[tex] = 63 + 134 - 17 = 180[/tex]

[tex] = 63 + 117 = 180[/tex]

[tex] = 180 = 180[/tex]

Thus, the value of x we found out is correct.

Therefore, x = 67

Penny reads 13 pages in 1/4 hour. What is the unit rate for pages per hour? For hours per page?

Answers

Answer:

52 pages per 1 hour

Step-by-step explanation:

If Penny reads 13 pages in 1/4 of an hour you need to multiply 13 by 4 to see how many pages she will read in 1 hour.

The unit rate:

52 pages per hour.

0.02 hours per page.

What is division?

One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.

To find the unit rate of pages per hour, we need to convert 1/4 hour to hours first.

1/4 hour = 0.25 hour

Then, we can use the formula:

Unit rate = Pages ÷ Time

Unit rate = 13 pages ÷ 0.25 hour

Unit rate = 52 pages per hour

To find the unit rate of hours per page, we can use the reciprocal of the previous unit rate:

Unit rate = Time ÷ Pages

Unit rate = 0.25 hour ÷ 13 pages

Unit rate = 0.0192 hours per page

Rounded to the nearest hundredth, the unit rate is 0.02 hours per page.
