A block is a rectangle that measures 100yards by 76yards. How many times around the block do you have to drive in order to drive one mile?

We can see that the unit rate of y = 6.5*x is larger than the unit rate on the graph.

The unit rate is the equal to the slope of the line.

In the written line, y = 6.5*x, the unit rate is 6.5

On the graphed line we can see that it passes through the points (0, 0) and (1, 3), so the unit rate is:

[tex]r = \frac{3 - 0}{1 - 0} = 3[/tex]

Then we can see that the unit rate of y = 6.5*x is larger than the unit rate on the graph.

Step-by-step explanation:

Givens

Harpreet        = x + 3

Sukhpreet     = x

Komalpreet   = 2*(x + 3)

Average Age = 15

Equation

[(x + 3) + x + 2*(x + 3) ] / 3 = 15                  Multiply both sides by 3

Solution

3 [(x + 3) + x + 2*(x + 3) ] / 3 = 15 * 3         Combine

 [(x + 3) + x + 2*(x + 3) ]       =   45             Remove the brackets

x + 3 + x + 2x + 6                 =   45             Combine like terms

4x + 9 = 45                                                 Subtract 9 from both sides

4x + 9 - 9 = 45 - 9                                       Combine

4x = 36                                                         Divide by 4

4x/4 = 36/4

x = 9

Answer:

89.25%

Step-by-step explanation:

65 is the lowest so it only counts for 20% of the grade

65*0.2=16.25

80*0.25=20

92*0.25=23

There is 30% left and 100% is the highest score

100*0.3=30

16.25+20+23+30=89.25

Answer:

86%

Step-by-step explanation:

From the information give:

Exam 1

Exam result = 65%

Overall grade weighting = 20%

⇒ Credit = 65% of 20% = 0.65 × 0.2 = 0.13 = 13%

Exam 2

Exam result = 80%

Overall grade weighting = 25%

⇒ Credit = 80% of 25% = 0.8 × 0.25 = 0.2 = 20%

Exam 3

Exam result = 92%

Overall grade weighting = 25%

⇒ Credit = 92% of 25% = 0.92 × 0.25 = 0.23 = 23%

Final Exam

The highest grade Brian can earn = 100%

Overall grade weighting = 100% - 20% - 25% - 25% = 30%

⇒ Credit = 100% of 30% = 1 × 30% = 30%

Highest potential class grade

Sum of each exam credit:

⇒ 13% + 20% + 23% + 30% = 86%

Therefore, the highest grade possible that Brian can earn in the class is 86%.

Answer:

59°

Step-by-step explanation:

ABC and ADF are congruent (that is the meaning of that symbol).

that means all their associated angles and side lengths are the same.

it is relatively clear to see that

A corresponds to A.

D corresponds to B.

F corresponds to C.

therefore, the angle D = angle B = 59°.

FYI - it also means that AD = AB = 16. but this information was actually irrelevant for this question.

The domain (input values) of the cosine function is all negative and positive angle measures.

Let the function be f(x) = cos(x)

The domain of cos(x) is -∞ < x < ∞

The range is -1 ≤ f(x) ≤ 1

Hence, domain of cos(x) is all (+) and (-) angle measures.

Same goes with sine function as well

For function f(x) = sin(x)

The domain is -∞ < x < ∞ and range -1 ≤ f(x) ≤ 1

However for f(x) = tan(x) the same is not applicable.

Answer:

A.  all negative and positive angle measures.

Step-by-step explanation:

The domain of a function is the set of input values (x-values).

The cosine function is a continuous function, and therefore has no restrictions throughout its domain.

Therefore, its domain is all real numbers.

Answer:

k = -10

Explanation:

f(x) = 4x³ - 3kx² + 44x - 30

The divisor is:

Set divisor to zero:

Insert this into equation.

⇒ 4(2)³ - 3k(2)² + 44(2) - 30 = 210

⇒ 32 - 12k + 88 - 30 = 210

⇒ -12k + 90 = 210

⇒ -12k = 210 - 90

⇒ -12k = 120

⇒ k = 120/-12

⇒ k = -10

Answer:

k = -10

Step-by-step explanation:

From the remainder theorem, we know that the remainder, 210, is equal to f(2).

∵ [tex]f(2) = 210[/tex] ,

⇒  [tex]4(2)^3 - 3 k(2)^2+44(2) - 30 = 210[/tex]

⇒  [tex]32 -12k + 88 - 30 = 210[/tex]

⇒  [tex]90 - 12k = 210[/tex]

⇒  [tex]-12k = 120[/tex]

⇒  [tex]k = -10[/tex]

Answer:

1 child - 60 another child - 50

Step-by-step explanation:

we start from the end. they had a equal number.

child A lost half therefore we give them another half having 2 units as shown in the diagram. child B had 1 unit plus 20 because he lost 20 which total adds up to 110. from there you have

3 units + 20 = 110

3 units = 90

1 unit = 30

since A has 2 units,

30 × 2 = 60

child A has 60.

since B has 1 unit plus 20

30 + 20 = 50

The perimeter of the park is 3x^2 + 37x - 4

The side lengths of the triangular park are:

10x + 3x^2 - 8, 12x and 15x + 4

Add these sides to determine the perimeter

P = 10x + 3x^2 - 8 + 12x + 15x + 4

Collect the like terms

P = 3x^2 + 10x + 12x + 15x - 8 + 4

Evaluate the sum

P = 3x^2 + 37x - 4

Hence, the perimeter of the park is 3x^2 + 37x - 4

A linear function is modeled by:

In which:

When two lines are perpendicular, the multiplication of their slopes is of -1. Hence, considering it is perpendicular to 2x + 3y = 4.

[tex]2x + 3y = 4[/tex]

[tex]3y = -2x + 4[/tex]

[tex]y = -\frac{2x}{3} + \frac{4}{3}[/tex]

Then:

Quadrilaterals are plane shapes with four sides. Thus, the required answers are:

a) The first shape is a right trapezoid.

b) The second shape is a parallelogram.

The given properties are that of a quadrilateral, thus both shape is a quadrilateral. A quadrilateral is a family of shapes that have four straight sides. Examples include squares, rhombus, kites, etc.

A. Given that the shape has one right angle and parallel sides. Then considering the given properties, the most likely shape is a right trapezoid.

A right trapezoid is a type of trapezium that has one right angle, and a pair of parallel sides. Thus the shape here is a right trapezoid.

Other shapes could be ruled out by comparing their properties with the properties of the shape given in the question.

B. The properties of the required shape as given are: it has two pairs of congruent opposite sides, and 2 pairs of opposite parallel sides. Thus the most likely shape required here is a parallelogram. A parallelogram is a shape with parallel and congruent opposite sides, and no right angle.

Other shapes could be ruled out by comparing their properties with the properties of the shape given in the question.

Question

64^m

--------

4^2m

Solution

(64)^m = (4^3)^m = 4^3m

4^3m/4^2m = 4^(3m - 2m) = 4^m

Answer

2^2m = (2^2)^m = 4^m                     Equivalent

16^0.5m = (16^0.4) ^m = 4^m          Equivalent

4^m                                                    Equivalent

All three of these are equivalent. The catch is in splitting the powers apart.  In this top one (2^2m) you move the brackets so that the right bracket is after the two which gives (2^2)^m =  4m

You do the same thing with (16^0.5)^m.  16^0.5 = 4 So the answer is 4^m

The last one is 4^m which is the answer you got from the division.

Given expression: [tex]64^{m} /{4^{2m} }[/tex]

We can rewrite the expression (in the numerator and the denominator) as the product of multiple fours. Then, we can apply the exponent rule to simplify the expression to its simplest form. The simplest form will be the required simplified expression (solution to the provided expression).

We can apply the following exponent rule to simplify the expression:

[tex]\boxed{\text{Exponent rule:} \ 4^{m} /4^{n} = 4^{m - n}}[/tex]

The exponent rule states that the "base" must be the same when subtracting exponents. If we divide a term with same bases, we can reduce work time by subtracting the exponent to simplify the expression.

Now, let us look at all the options to verify which term matches our simplified term, and which expressions do not match our simplified term.

Given term: [tex]2^{2m} \\[/tex]

Can be re-written as:

Simplifying the expression inside the long brackets:

Therefore, the first option is equivalent to our simplified term.

Given term: [tex]16^{0.5m}[/tex]

Can be re-written as:

Exponent Rule: (xᵃ)ᵇ = xᵃᵇ

Therefore, the second option is equivalent to our simplified term.

Given term: [tex]4^{m}[/tex]

This term already matches our simplified term.

Therefore, the third option is equivalent to our simplified term.

We can conclude that all the options provided are equivalent to the given expression. We proved it by applying exponent rules and formulas.

The parameters are:

For this problem, the values of the parameters are given as follows:

N = 15, n = 4, k = 10.

The probability that all the four students like pizza is P(X = 4), hence:
