The solution is,  that the answer to your question would be that the subject(s) of the sentence is/are the following one/s: Tablet, pens. That is, the correct option would be B.

In this sentence, the PP indicating the location of the tablet of paper and the pens appears in initial position in the sentence.

The sentence sounds odd and is not grammatically correct because in these cases an existential there is introduced.

Take a,

a) In the desk drawer, there are a tablet of paper and some pens

b) *In the desk drawer, are a tablet of paper and some pens

The NP "a tablet of paper and some pens" would function as the subject complement and the existential there acts as grammatical subject filler(a).

In A'B'C'D, line segment A'B has a slope of 0 and a length of 5/4

From the question, we have the following parameters that can be used in our computation:

A = (1, 4) and B = (6, 4)

The line AB is a horizontal line that passes through the point y = 4

This means that the slope of the segment A'B' is 0

The length is then calculated as

A'B' = difference in the x-coordinate * scale factor

Substitute the known values in the above equation, so, we have the following representation

A'B' = (6 - 1) * 1/4

Evaluate

A'B' = 5/4

Hence, the length A'B' is 5/4

Answer:

m∠R=x=37°; m∠QOR=53°

Step-by-step explanation:

Any line that is tangent to a circle (such as QR) is perpendicular to the circle's radius (QO). Therefore, ΔOQR is a right triangle, with the right angle at Q.

1. You can use  90 + (x+16) + x = 180   or    (x+16) + x = 90 to solve for x.

2. If needed, you can then use the solution from step 1 to find the measure of ∠QOR.

The length of segment PQ is equals to the length of segment P'Q' divided by 1.5, that is:

PQ = P'Q'/1.5

A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.

The scale factor for this problem is given as follows:

k = 1.5.

Hence the equation relating the lengths PQ and P'Q' is given as follows:

P'Q' = 1.5PQ

PQ = P'Q'/1.5

(as the length on the dilated figure is the original length multiplied by the scale factor).

The probability of rolling an even or divisible by 3 numbers is 2/3

When a single fair die is rolled, there are six possible outcomes:

1, 2, 3, 4, 5, or 6.

Of these outcomes, three are even (2, 4, and 6) and two are divisible by 3 (3 and 6). However, since the number 6 is both even and divisible by 3, we must count it only once to avoid overcounting. Thus, four outcomes are either even or divisible by 3: 2, 3, 4, and 6.

The probability of rolling an even or divisible by 3 number is the sum of the probabilities of these four outcomes, which is:

P(even or divisible by 3) = P(2) + P(3) + P(4) + P(6)

= 1/6 + 1/6 + 1/6 + 1/6

= 4/6

= 2/3

Therefore, the probability of rolling an even or divisible by 3 numbers is 2/3

From the given figure we can see that the figure is a pyramid.

The base of the pyramid is a square.

The each side of base square i = 24.8 in.

The slant height is = 37.6 in.

So the right angle formed in between prism has hypotenuse = 37.6 in.

one of the rest two sides = 24.8/2 = 12.4 in.

So another side is the height of the pyramid. Let that side be = x in.

By Pythagoras Theorem we get,

153.76 + x² = 1413.76

x² = 1413.76 - 153.76

x² = 1260

x = 35.5 (rounding off to nearest tenth and neglecting the negative value obtained from square root as length cannot be negative.)

Step-by-step explanation:

The margin of error represents the range of values within which the true population mean is likely to fall with a certain level of confidence. To calculate the range of values for the actual mean number of hours spent in meetings in a week, we can use the formula:

(actual mean) = (sample mean) ± (margin of error)

Substituting the given values, we get:

(actual mean) = 4.3 ± 1.1

To find the range of values, we need to compute the upper and lower bounds of this interval:

Lower bound = 4.3 - 1.1 = 3.2 hours

Upper bound = 4.3 + 1.1 = 5.4 hours

Therefore, the actual mean number of hours spent in meetings in a week is between 3.2 and 5.4 hours.

The statements that are true are ;

1. tan(tetha) = -√3

2. the measure of the reference angle is 60°

The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

The value of each angle depends on the quadrant it falls on.

First quadrant = 0-90°

second quadrant = 91° -180°

third quadrant = 181-270°

fourth quadrant = 271° - 360°

pi is measurement of angle in radians which is equivalent to 180°

therefore;

2π/3 = 2 × 180/3 = 360/3

= 120°

120 falls on the second quadrant,

Answer:

let the children be x

let the dog be y

for the heads

x+y = 14 --- eqn 1

for the legs

2x + 4y = 40 ----- eqn2

since the children have 2 legs each and the dogs have 4 legs each

x + y = 14

2x+4y=40

through elimination method

multiply eqn1 by 2 and multiply eqn2 by 1

2x + 2y = 28

2x + 4y = 40 , then subtract

-2y = -12

to get y divide both sides by -2

y = 6

since in eqn 1

x+y=14

x = 14-y = 14-6 = 8

x = 8, y = 6

the children are 8 while the dogs are 6

Answer:n=-7

Step-by-step explanation: (-2y+5)+(-5y-3)=-7y+2 so our answer is -7.

a. To create an exponential model for new cases in terms of days, we can use the formula: y = a * b ^ x, where y is the number of new cases, x is the number of days since the first observation, and a and b are constants that we need to determine. Using the two data points given, we can set up a system of equations:

235 = a * b ^ 0

395 = a * b ^ 10

Solving for a and b, we get:

a = 235

b = (395/235)^(1/10) = 1.067

Therefore, the exponential model for new cases in Milwaukee is:

y = 235 * 1.067 ^ x

b. To find the number of new cases on Oct. 31, 2020, we need to plug in x = 19 (since Oct. 31 is 19 days after Oct. 12) into the model:

y = 235 * 1.067 ^ 19 = 1018.5

Therefore, based on the exponential model, we would expect around 1019 new cases on Oct. 31, 2020.

c. The actual number of new cases on Oct. 31, 2020, was 1043. This is higher than the predicted value of 1019, but not by a huge margin. Overall, the model seems to fit the data reasonably well, especially considering that there are many factors that can affect the number of new cases in a given area, and that the model is based on only two data points. However, it is worth noting that the exponential model assumes that the growth rate of new cases remains constant over time, which may not be a realistic assumption in the long run.

The model predicts that the number of stores will be at a minimum of approximately 8,123 stores in the year 2009, and will increase from there without bound.

A cubic function is a type of polynomial function with the highest degree term being 3. In other words, a cubic function is a function of the form[tex]f(x) = ax^3 + bx^2 + cx + d[/tex], where a, b, c, and d are constants. The graph of a cubic function is a curve that can take on various shapes depending on the values of the coefficients.

b) To find the predicted number of stores in 2020, we need to find the value of the function when x = 20 (since 2020 is 20 years after 2000). We can substitute x = 20 into the function and evaluate:

[tex]y = 10.4x^3 - 403x^2 + 5585x - 8695\\y = 10.4(20)^3 - 403(20)^2 + 5585(20) - 8695\\y = 140,385[/tex]

Therefore, the model predicts that the number of stores in 2020 will be 140,385.

c) To determine if the number of stores ever decreases over the period of years ending in 2020 according to the model, we can look at the behavior of the function. The function is a cubic function with a positive leading coefficient, which means it will have a global minimum (i.e., the lowest point on the graph) and then increase without bound as x approaches positive or negative infinity.

To find the global minimum, we can take the derivative of the function and set it equal to zero:

[tex]y' = 31.2x^2 - 806x + 5585\\0 = 31.2x^2 - 806x + 5585[/tex]

x ≈ 8.68 or x ≈ 22.12

The first solution, x ≈ 8.68, is within the range of interest (2000 to 2020), so we can use it to find the global minimum:

[tex]y = 10.4x^3 - 403x^2 + 5585x - 8695[/tex]

y ≈ 8,123

Therefore, the model predicts that the number of stores will be at a minimum of approximately 8,123 stores in the year 2009, and will increase from there without bound. So according to the model, the number of stores never decreases over the period of years ending in 2020.

So the new balance would be:

After the second quarter, the interest earned would be:

After the fourth quarter, the interest earned would be:
