Answer: 116°

Step-by-step explanation:

The measure of arc AD is 116 degrees and it can be determined by using the properties of a circle.

Given that,

Angle ABD measures (4x + 10).

Angle ACD measures (5x − 2).

Circle E is shown.

Angles ABD and ACD intercept arc AD.

Angles BAC and BDC intercept arc BC.

We have to determine,

What is the measure of arc AD?

According to the question,

Angle ABD measures (4x + 10).

Angle ACD measures (5x − 2).

Circle E is shown.

Angles ABD and ACD intercept arc AD.

Angles BAC and BDC intercept arc BC.

In the given condition, Angle ABD and Angle ACD have inscribed angles, intercepting the same arc then by the intercept arc property.

Angle ABD = Angle ACD

[tex]\rm 4x+10 = 5x-2\\\\4x-5x = -2-10\\\\-x = -12\\\\x=12[/tex]

The value of x is 12.

Therefore,

The measure of arc AD is,

[tex]\rm Arc \ AD =A ngle \ ABD + Angle \ ACD\\\\Arc \ AD = (4x+10) + (5x-2)[/tex]

Substitute the value of x,

[tex]\rm Arc \ AD = (4x+10) + (5x-2)\\\\Arc \ AD = 4(12) +10+5(12) -2\\\\Arc \ AD = 48+10+60-2\\\\Arc \ AD = 116 \ degree[/tex]

Hence, the measure of arc AD is 116 degrees.

Answer:

A :  Per 100 people, cashier should expect 26 customer until he finds a costumer that makes a purchase.

B:   The probability is 1/4

Step-by-step explanation:

The estimated chance of a customer making a purchase  = 74%

So, if a TOTAL of 100 people visit the grocery store on any random day,

then 74 % of customers  

= 74% of 100

= 74 people will make purchases.

⇒ Out of total 100 people visiting, 74 people  will make a purchase.

So, the number of people NOT making a purchase = 100 - 74 = 26

⇒ Out of total 100 people visiting, 26 people  will NOT make a purchase.

Also, 26 = 26% of 100

Part A :

So, in order to make a purchase, cashier should expect 26% of customers because the percentage of NOT purchasing is 26%.

Hence, per 100 people, cashier should expect 26 customer until he finds a costumer that makes a purchase.

Part B :

The percentage of customer making a purchase = 74%

The percentage of people NOT making a purchase  = 26%

So, for every 3 customer making a purchase there is a 1 person NOT making  a purchase.

So, the probability is 1/4

Part A) 

1.35 customers until the cashier should expect to find a customer that makes a purchase.

1 ➗ 0.74 = 1.35

Part B)

0.013 is the probability that the cashier helps 3 customers until he finds the first person to make a purchase.

(1 - 0.74)3 x 0.74 = 0.013

Answer:( 8, 6)

Step-by-step explanation:

After rotating the point (-6,8) 90° clockwise about the origin, the new position of the point will be (8,6).

When a point is rotated 90° clockwise about the origin in a two-dimensional Cartesian coordinate system, the new position of the point can be calculated by changing the sign on the y-coordinate and swapping the order of the x and y-coordinates. For your specific question, we are given the point (-6,8). So, the new position of the point after the rotation would be (8,6). This is because rotations in a clockwise direction can be considered as negative in mathematics, and portions rotate around the origin following the right-hand rule.

Final answer:

Area of the rectangle that has the vertices (-2, 0). (0-4). (2.0), and (0,4)  is 32 square units.

Explanation:

To find the area of a rectangle, we need to use the formula:

Area = length x width

In this case, the vertices of the rectangle are (-2, 0), (0, -4), (2, 0), and (0, 4). We can calculate the length and width by finding the difference in the x-coordinates and y-coordinates, respectively.

The length is 2 - (-2) = 4 and the width is 4 - (-4) = 8.

Therefore, the area of the rectangle is:

Area = 4 x 8 = 32 square units.

The polynomial x^2 + 18 cannot be factored over the real numbers and remains in its simplest form. For complex coefficients, it can be expressed as (x + 3i)(x - 3i). For cubic differences like x^3 - y^3, the real factors would be (x - y)(x^2 + xy + y^2).

The polynomial x2 + 18 cannot be factored over the reals because it does not have any real roots; thus, it is already in simplest form over the real numbers. However, if we allow for complex coefficients, we can write this as (x + 3i)(x - 3i), where i is the imaginary unit. Note, for more complex expressions such as x3 - y3, you would use the formula (x - y)(x2 + xy + y2) to factor it over the reals or apply complex coefficients if necessary.

Answer:

D. 3 x 9/5

Step-by-step explanation:

The expression that has the same value as 3 ÷ 5/9 is 13 ÷ 5/9.

The expression that has the same value as 3 ÷ 5/9 is option B. 13 ÷ 5/9.

To divide by a fraction, we multiply by its reciprocal. In this case, we can find the reciprocal of 5/9, which is 9/5. So, we have 3 ÷ 5/9 = 3 × 9/5 = 27/5.

Option B, 13 ÷ 5/9, is equivalent to 13 × 9/5 = 117/5, which is equal to 27/5. Therefore, option B has the same value as 3 ÷ 5/9.

Dividing by 8

16/8: 8/8

2:1

Answer: B

Step-by-step explanation:

there are 24 cookies in total and 16 of then are chocolate chip.To find the rest of the cookies, you would subtract 16 from 24 which would give you 8.

Finally, to make a ratio, you would put the numbers in order as the problem. So, that would be 16:8 or chocolate chip to sugar. and that would reduce to 2:1.

In order to write the above statement as an equation, we have: b + 8 = 17.

Answer: The answer is 8.

Step-by-step explanation: The first step is to convert the expression into figures. We shall call the unknown number Y. So if we are told “the square of a number,” that means Y squared, or better still, Y^2. Further we are told “the difference between the square of a number and 40” and that can be written as;

Y^2 - 40.

Next we are told that this expression is equal to 3 times that number (that is 3Y). That can now be written out as follows,

Y^2 - 40 = 3Y

If we move all expressions to one side of the equation, what we would have is,

Y^2 - 3Y -40 = 0

(Remember that when a positive value crosses to the other side of an equation it becomes negative and vice versa)

We now have a quadratic equation

Y^2 -3Y - 40 = 0

By factorizing we now have

(Y -8) (Y + 5) = 0

Therefore Y - 8 = 0 or

Y + 5 = 0

Hence, Y = 8 or Y = -5

Since we are asked to calculate the positive solution, Y = 8

Answer:4m^2+4m+1

Step-by-step explanation:

(2m+1)^2=(2m+1)(2m+1)

Opening brackets we have:

4m^2+2m+2m+1

Add like terms

4m^2+4m+1

Answer:

The solution is

4m² + 4m + 1

Step-by-step explanation:

Solve this: (2m+1)²

If X² = X*X

Therefore, (2m+1)² = (2m+1) x (2m+1)

Opening the bracket (2m+1) x (2m+1)

=2m*2m + 2m*1 + 1*2m + 1*1

= 4m² + 2m + 2m + 1

Collect the like terms

= 4m² + 4m + 1

From this point, the equation can't be solved further.

Answer:

Option  D. 7°C

Step-by-step explanation:

Let the temperature in Fahrenheit (F) and the temperature in Celsius(C)

The formula to convert Fahrenheit to Celsius is ⇒ F = 1.8 C + 32

So, to Convert 45° F to Celsius, substitute with with 45° F

45 = 1.8 C + 32

Solve for C

1.8 C = 45 - 32

1.8 C = 13

C = 13/1.8 = 7.222

Rounding to the nearest degree ⇒ 45° F = 7° C

The answer is option  D. 7°C

The height of the cone is 4 inches.

Step-by-step explanation:

Step 1:

The given triangle is a right-angled triangle.

The length of the hypotenuse is 5 inches. One of the other sides is 3 inches long. Assume the other side of the triangle measures x inches.

According to Pythagoras' theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Step 2:

(The length of the hypotenuse)² = (The other sides length)² + (The other sides length)²

By substituting the values in the equation, we get

[tex]5^{2} = 3^{2} + x^{2} , x^{2} = 25 - 9 = 16.[/tex]

[tex]x = 4.[/tex]

So the height of the cone is 4 inches which is the fourth option.

Answer:

No, because the end of the number is 8 and numbers divisible by 5 has to end in 0 or 5.

Answer:

No

Step-by-step explanation:

9,056,198 is not divisible by 5.

Being divisible means that the number can be divided by the other without there being any decimals. Meaning it has to divide into a whole number in order to be divisible.

An easy way to see if anything is divisible by 5 is to see if the last number is either a 0 (for example 10 or 20) or if the last number is a five (for example 15 or 25)
