Answer:

p=50t

Step-by-step explanation:

The more pages Crystal has to read, the more time she spends reading.

Let p=number of pages read

t=time spent reading the number of pages

As t increases, p increases.

This is a direct proportion and we can write it as:

\(p=tk$ where k is the constant of proportionality\\When $ t=\frac{1}{2} $ hour, p=25 pages\\Therefore:\\25=0.5k\\k=25\div 0.5\\k=50\)

Substitution of k into p=tk gives:

p=50t

Therefore, an equation representing the relationship between the number of pages Crystal reads and how much time she spends reading is:

p=50t

         Tip: You seem like you are slightly stuck. That is okay! Don't forget the formulas that can help you solve for the circumference. When you can solve for the circumference, the rest of the answers come a bit easier.

[a] 88 inches

         The circumference can be found with C = 2πr, but they tell us to use \(\frac{22}{7}\) instead of pi, so we will do just that.

C = 2 * \(\frac{22}{7}\) * r

C = 2 * \(\frac{22}{7}\) * (14)

C = 88

[b] 176 inches

         Again, the circumference can be found with C = 2πr, but they tell us to use \(\frac{22}{7}\) instead of pi, so we will do just that.

C = 2 * \(\frac{22}{7}\) * r

C = 2 * \(\frac{22}{7}\) * (28)

C = 176

[c] When you double the radius, the circumference also doubles.

         We will divide the second circumference by the first circumference  so we can see how they compare:

176 / 88 = 2

         Now we will take the second radius divided by the first radius:

28 / 14 = 2

         We could use a longer explanation, but in summary, when the radius is doubled the circumference is also doubled as seen with the value 2.

The true statement about the sampling distribution is "the sampling distribution of a statistic is a distribution that we should approximate in exercise by taking many small samples."

The sampling distribution is the theoretical distribution of a statistic (including the imply, median, or variance) based totally on all viable samples of a given size that could be taken from a population. it is a beneficial idea in statistics as it allows us to make inferences approximately the populace based on records gathered from a pattern.

In practice, we can not examine the whole sampling distribution, as it's far based totally on all viable samples, which isn't always feasible to gain. but, we will approximate the sampling distribution by taking many small samples from the population and calculating the applicable statistic for every sample.

Because the variety of samples increases, the distribution of these data will converge to the sampling distribution, allowing us to make more accurate inferences approximately the population.

Answer:

111°

Step-by-step explanation:

The polygon given is a heptagon having 7 sides.

Sum of interior angles of a 7-sided polygon = (n - 2)*180

= (7 - 2)*180

= 5*180 = 900°

Therefore:

126° + 158° + 120° + 125° + 121° + 139° + x° = 900°

Solve for x

789° + x° = 900°

Subtract 789 from each side

x = 900° - 789°

x = 111°

Answer:

75 cm

Step-by-step explanation:

It is given that the triangles are similar. It means that the ratio of their areas are equal to the ratio of their bases and ratio of their altitudes.

Let \(A_1\) be the area of 1st triangle.

Let \(A_2\) be the area of 2nd triangle.

Let \(h_1\) be the altitude of 1st triangle.

Let \(h_2\) be the altitude of 2nd triangle.

Let \(b_1\) be the base of 1st triangle.

Let \(b_2\) be the base of 2nd triangle.

Then \(A_1: A_2 = h_1 : h_2 = b_1 : b_2 ...... (1)\)

\(A_1 = 42 cm^{2} \\A_2 = 262.5 cm^{2}\\h_1 = 7 cm\\b_2 = ?\)

We know that area of a triangle is:

\(A = \dfrac{1}{2} \times b \times h\)

Area of smaller triangle:

\(\frac{1}{2} \times b_1 \times 7 = 42\\\Rightarrow b_1 = 12 cm\)

Now, using part of equation (1):

\(A_1: A_2 = b_1 : b_2 \\\Rightarrow \dfrac{42}{262.5} = \dfrac{12}{b_2}\\\Rightarrow b_2 = 75 cm\)

Hence, base of larger triangle = 75 cm

Answer:

GH = 9 units

Step-by-step explanation:

Given HI = 4b - 5 and HI 3, then

4b - 5 = 3 ( add 5 to both sides )

4b = 8 ( divide both sides by 4 )

b = 2

Thus

GI = 5b + 2 = 5(2) + 2 = 10 + 2 = 12

GH = GI - HI = 12 - 3 = 9

The relation for time and distance  will be written as D = 40t miles.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Given that the speed of the eagel is 40 miles per hour. The relationship between the distance and the time will be calculated as,

Distance = Speed x Time

Distance =  40 x Time

D = 40t miles

Here t, is in hours.

Answer:

  (d)  f(x) = (x − 3)^2(x − 2)(x − 1)

Step-by-step explanation:

In this context, a crossing of the axis at x=p means there is a factor of (x-p). A "touch" of the axis at x=q means there is a factor of (x -q)^2.

A crossing at x=1 and x=2, and a touch at x=3 means the factors are ...

  f(x) = (x -1)(x -2)(x -3)^2 . . . . . matches the last choice

Answer:

● to make n subject you first cross m^2 to the other side

● then divide both sides by the coefficient of n^2

● then take the square root of both sides

\( \\y = {m }^{2} - {4n}^{2} \\ y - {m }^{2} = {4n}^{2} \\ taking \: square \: root \: of \: bothsides\\ \sqrt{\frac{y - {m}^{2}}4} = n \\ solved.\)

ANSWER and EXPLANATION

We have that twice a number is increased by a different number and that is equal to 15.

a) Let the first number be x.

Let the second number be y.

This means that:

2x + y = 15

b) To find the possible numbers that can solve this, we have to pick random values of x, then use that to find the values of y.

Let us pick x as 3, 6 and 9.

When x = 3:

2(3) + y = 15

6 + y = 15

=> y = 15 - 6

y = 9

When x = 6:

2(6) + y = 15

12 + y = 15

y = 15 - 12

y = 3

When x = 9:

2(9) + y = 15

18 + y = 15

y = 15 - 18

y = -3

These are some possible solutions to the equation.

c) The graph of this equation would be continuous.

A continuous graph is one whereby x take any values not some particular values.

Because the question does not classify the kind of numbers, the numbers could be any numbers, and so, the graph would be continuous.
