C. 4 x (5 x 2) = 40 hope that helps

Answer : option C

A. 4 × (5 + 2) = 28

Associative property of multiplication . Here we have 5+2 so it does not comes under Associative property of multiplication

B. 4 + (9 × 4) = 40

Here we have 4 + . there is a + sign inbetween.  so it does not comes under Associative property of multiplication

C. 4 × (5 × 2) = 40

Here we have 4 times 5 times 2.  so it comes under Associative property of multiplication

D. (4 + 5) × 2 = 18

Here we have 4 + 5 so it does not comes under Associative property of multiplication

Answer:

2.7 x 1016

Step-by-step explanation:

that's the answer

The range is the difference between the highest number and the lowest number.

The lowest number is 5, the highest number is 13.

The range is 13 - 5 = 8 runs.

The correct answer for the range is: "5 to 13 runs" with a median of 8  and here is why:

The range of a set of numbers is what values could have or could be based on the lowest and highest values. The range is not the same as the average or the median. 5 runs was the least amount of runs that happened during one game and 13 was the most in another.

The average is calculated by adding all of the numbers added together and then divides by how many numbers that you added together.

The median is found by removing the lowest number and then the highest number. You repeat this process until you are left with only one number.

There are other things to find as well, but I think you understand now

Range: 5-13 ; 8

Average: 9

Median: 8

Also here is the definition from Dictionary.com on what range is:

range   rānj/Submit

noun

1.the area of variation between upper and lower limits on a particular scale.

ex: "the cost is thought to be in the range of $1-5 million a day"

The correct option is:   B.  length: 14 cm, width: 6.4 cm

Explanation

The actual length of Lake Superior is 350 miles and the width is 160 miles.

The scale is given as:  1 cm = 25 miles

Suppose, the length and width of the lake on the map are  [tex]x[/tex] cm and [tex]y[/tex] cm respectively.

First, the equation according to the ratio of scaled length to the actual length will be....

[tex]\frac{x}{350}=\frac{1}{25}\\ \\ 25x=350\\ \\ x=\frac{350}{25}=14[/tex]

Now, the equation according to the ratio of scaled width to the actual width will be....

[tex]\frac{y}{160}=\frac{1}{25}\\ \\ 25y=160\\ \\ y=\frac{160}{25}=6.4[/tex]

Thus, the length and width of the lake on the map will be 14 cm and 6.4 cm respectively.

The question says that Frances gets 6 paychecks in 1 week.

To find the number of paychecks that Frances gets paid in 52 weeks we need to know the number of paychecks she gets each week.

She gets 6 paychecks each week,

So that means,

1 w = 6 paychecks

So, in 52 weeks she will get:

[tex]6 \times 52=312[/tex] paychecks.

Over the duration of 52 weeks, Frances gets 312 paychecks.

Answer:

The value of k is 5.

Step-by-step explanation:

Since we know we can convert function's quadratic form to vertex form by completing the square.

f(x)=x2?6x+14

We will add and subtract 9 to our equation in order to complete the square.

[tex]1(x^{2} ?6x+9)-9+14[/tex]

Upon completing the square and combining like terms we will get,

[tex]1(x?3)^{2} +5[/tex]

Upon comparing Willie's vertex form with our expression we can see that k is 5.

Therefore, the value of k is 5.

Answer:

Connor ordered 5 toppings on his pizza.

Step-by-step explanation:

17.50 + (2.35 * x) = 29.25

Remove the parentheses

17.50 + 2.35x = 29.25

Subtract 17.50 from both sides

2.35x = 29.25 - 17.50

Subtract

2.35x = 11.75

Divide both sides by 2.35

x = 5

Answer:

29.25 - 17.50 = 11.75

11.75 divided by 2.35 = 5

So that he had 5 toppings on his pizza.

Answer:

The exponent -9  makes the given statement true.

Step-by-step explanation:

We have been given an incomplete mathematical statement and we need to figure out the exponent for 5 on the right hand side to complete the statement.

The given incomplete statement is [tex]\frac{1}{5^{9}}=5^{?}[/tex].

Let us rewrite the left hand side of the expression by moving the exponential term to the numerator using exponent property. As per this property, if we shift an exponential term from denominator to numerator (or vice versa), the sign of exponent changes.

Therefore, we get:

[tex]5^{-9}=5^{?}[/tex]

Now that we have common bases on both the sides, we can equate the exponents. And upon equating the exponents, we can see that the 'question mark' should be replaced by -9 in order for statement to be true.

Therefore, exponent -9 on the right hand side will make the statement true.

Answer:

1/5^9 = 5^-9

Step-by-step explanation:

Let's assume

'a' , 'b' are zeros

so, we will find total zeros from graph

We can  curve touches x-axis

Let's assume it touches at x=b

so, there would be two zeros at x=b

it also crosses origin

so, another zero is at x=0

it crosses x-axis one more time

Let's assume that zeros at x=a

so, we have got four zeros

x=a,0,b,b

now, we can set up function

[tex]f(x)=(x-0)(x-a)(x-b)(x-b)[/tex]

we can also write as

[tex]f(x)=x(x-a)(x-b)^2[/tex].................Answer

Answer:

It is -4,-2

Step-by-step explanation:

Answer:

The solution is (-4, -2)

Step-by-step explanation:

Given two equations

[tex]2x-5y=2[/tex]  →   (1)

[tex]3x+2y=-16[/tex]    →    (2)

we have to solve the system of equations by elimination method

Multiply (1) by 3 and (2) by 2 and then subtracting we get

[tex]3(2x-5y)-2(3x+2y)=6-(-32)[/tex]

[tex]6x-15y-6x-4y=38[/tex]

[tex]-19y=38[/tex]

[tex]y=-2[/tex]

⇒ [tex]2x=2+5(-2)=2-10=-8[/tex]

[tex]x=-4[/tex]

Hence, the solution is (-4, -2)

Step-by-step explanation:

We have arc length = Radius x Angle in radian

Radius = 26 inches

[tex]\texttt{Angle rotated }= 80^0=80\times \frac{\pi}{180}=\frac{4\pi}{9}[/tex]

Arc length = [tex]l=\frac{4\pi}{9}\times 26=11.56\pi[/tex]

All the sides of a square are equal.

Perimeter of a square = 4(measure of 1 side)

Therefore if a square contains 4 sides, and the measure of one side is 2 inches, the perimeter is 8 inches. (2x4)

The definition of directly proportional is when one substance increases at the same rate of another substance. When a number is plugged into our formula, the perimeter increases.

So, to set up your equation is the hardest part. If you remember the basic format, you're set.

I(t) = P * (1+r%)^t

t= time and this will be our variable

Initial amount P = $2740

Rate = 4.3% which converts numerically into .043

I(t) = 7000

Before we get to find out how to find how many years it takes to get to $7000, set up the basic equation by plugging in what we know.

I(t) = $2740(1+4.3%)^t

I(t)=2740(1.043)^t

Now plug in for $7000 for I(t)

7000=2740(1.043)^t                 Divide both sides by 2740

7000/2740 = 2740/2740(1.043)^t

2.55474453=(1.043)^t

Now you can solve for t in two ways. You can either use the natural log or graph it on your graphing calculate and see when the two equations meet.

In your calculator you can set up:

ln(2.55474453)/ln(1.043) = t                 which is the method I prefer since it's much simpler

t=22.278528

but you can also graph it in your ti-84

with

y1=2.55474453

y2=(1.043)^x

and find where they intersect on the graph.

either way it'll be the same answer

Answer:

Option B

Step-by-step explanation:

For answering this question we must understand what is a function.

A function is different from mapping.

Mapping is just a subset of AxB where A and B are two sets.

But function is constrained to the point that elements of I set will have unique image in second set.

We find From the options

But in option B,, we find that 1 has two images 3.3 and 4.5.  i.e. 1 does not have unique image. Hence not a function.

All other options the first element in ordered pair have a unique image.

Hence all other options are functions.

Only option B is not a function.

To graph 24x + 25 = -6y + 7, first rearrange it to the form y = mx + b. In our case, y = -4x -3. Plot the y-intercept (0, -3) first, then use the slope (-4) to find a second point (1, -7). Connect these points to form the graph.

To graph the equation 24x + 25 = -6y + 7, the first step is to rewrite the equation in slope-intercept form, or y = mx + b, where m is the slope of the line and b is the y-intercept (where the line crosses the y-axis).

Add 6y to both sides of the equation 24x + 25 = -6y + 7 to get 6y = 24x + 25 - 7. Then, rearrange the equations and divide all terms by 6 to get y = -4x - 3.

Now, we can identify the slope and y-intercept. The slope (m) is -4 and the y-intercept (b) is -3. Using these, we can plot two points on a graph. The first point is the y-intercept which is at (0, -3), the point where the line crosses the y-axis.

The slope of -4 means for every step to the right on the x-axis, we go down 4 steps. Therefore, our second point would be at (1, -7). Connect these two points with a straight line, and you have graphed the equation.
