The inequality that can be used to figure out how many cases Sandra is working on is: [tex]x + 8 > 29[/tex]

Step-by-step explanation:

She is working on "x" cases, then she adds 8 more to that number, therefore it is "x + 8" and we also know that the total number of cases she's working is more than 29, in other words, it is greater than 29. With this in mind we can create the following inequality:

[tex]x + 8 > 29[/tex]

The inequality that can be used to figure out how many cases Sandra is working on is: [tex]x + 8 > 29[/tex]

Answer:

C. Rolling a fair cube, with faces labeled one to six, ans the cube landing a number less than six.

Step-by-step explanation:

A. flipping a fair coin, and the coin landing on tails, has only got a 50% chance

B. Picking a red marble has only got 10% chance

C. Rolling the cube and getting a number less than 6 has got 5/6 chance, as, from one to six, 5 numbers are less than six.

D. the spinning an arrow similation has only got a 75% chance.

since 5/6 is greater than 3/4, Simulation C is more likely to occur

The event which is most likely to occur is  Rolling a fair number cube, with faces labeled one to six, and the cube landing a number less than six, correct option is C.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes.

We are given that;

A coin flip, bag of marbles, A fair number cube, an arrow spinner

Now,

The probability of an event is defined as the number of ways the event can occur divided by the total number of possible outcomes.

A. The probability of flipping a fair coin and getting tails is 1/2.

B. The probability of choosing a red marble out of a bag with nine blue marbles and one red marble is 1/10.

C. The probability of rolling a number less than six on a fair number cube is 5/6.

D. The probability of spinning the arrow on a spinner and landing on a number greater than one is 3/4.

Comparing the probabilities, we see that option C has the highest probability, with a probability of 5/6.

Therefore, by probability answer will be rolling a fair number cube and getting a number less than six is the most likely event to occur.

Slope measures the rate of change in the dependent variable as the independent variable changes. The greater the slope the steeper the line. Consider the linear function: y = a + bx. b is the slope of the line.

A steeper slope in a graph means that the rate of change is faster.

Two thirds of 56 is simply two thirds times 56, which can be written as follows:

Two/thirds x 56

Furthermore, you can convert "two" to "2" and "thirds" to "3" and then the equation and answer is:

2/3 x 56 = 37.33

Step-by-step explanation:

The multiplication of the numbers 56 and 2/3 will be 37.33.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The numbers are given below.

56 and 2/3

Then the multiplication of the numbers 56 and 2/3 will be

⇒ 56 x (2/3)

⇒ 112/3

⇒ 37.33

Thus, the multiplication of the numbers 56 and 2/3 will be 37.33.

Answer:

Area is πr²

Step-by-step explanation:

The area of a circle is given as

A = πr²

Where r, which is half of the circumference of the circle, is the radius of the circle.

Where π = 3.14...

Answer:

πr2.

Step-by-step explanation:

The shape changed, but the amount of space inside the shape remained the same. The space inside the parallelogram is the same as the space, or area, inside the circle. The area of the circle is 0.5 × circumference × radius = πr2.

Answer:

4502 pieces of grass

Step-by-step explanation:

The radius of the semicircle is 36 meters, so its perimeter is:

Perimeter = pi * radius = 113.097 m

The perimeter of both semicircles is 2 * 113.097 = 226.194 m

So if the total perimeter is 395, the length of the rectangle is:

395 = 226.194 + 2*length

2*length = 168.8

length = 84.4 m

The width of the rectangle is 2 times the radius of the semicircle, so:

width = 2 * 36 = 72 m

Then the area of the rectangle is:

Area = length * width = 84.4 * 72 = 6076.8 m2

To find the number of grass pieces, we divide the rectangle area by the grass piece area:

number of pieces = 6076.8 / 1.35 = 4501.33 pieces

So we will need 4502 pieces to cover the rectangular area.

-0.45 x + 0.33 = -0.66

Adding -0.33 to both sides

-0.45 x = -0.99

Dividing both sides by -0.45

x = -0.99 / -0.45 = 2.2

Answer: x = 2.2, last choice

Income Tax  = 10/100 * $1287.50 = $128.75

Thus, federal income tax is $128.75.

Answer:

No, because they are parallel.

Kevin says that lines p and m will eventually intersect. The statement is incorrect because lines p and m are parallel.

Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other. Perpendicular lines are those that cross at a straight angle of 90 degrees.

It is given that lines A and B intersect. Plane A contains lines p, m, and n. Line n is horizontal on the plane. Lines p and m are both going in the same direction and are identical. Plane B contains vertical line l which forms a right angle with line n.

In the image attached with the answer below it is observed that the two lines p and m are in the same plane and are parallel to each other.

Therefore, the statement given by Kevin is incorrect.

Answer:

H = 120°

Step-by-step explanation:

The sum of the internal angles of a polygon with n sides is given by the formula:

S = (n-2)*180

So, for a pentagon, we have n = 5, then:

S = (5-2)*180 = 540°

So we have that:

M + A + T + H + S = 540° (eq1)

M = T = H (eq2)

A + S = 180° (eq3)

Using the second and third equation in the first one, we have:

H + H + H + 180 = 540

3H = 360

H = 120°

Answer:

50 = x

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles

105 = 55+x

Subtract 55 from each side

105-55 = 55-55+x

50 = x

Answer:

A

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

105° is an exterior angle of the triangle , thus

x + 55 = 105° ( subtract 55 from both sides )

x = 50° → A

Answer: Yes I agree with Jada. His approach is correct.

Step-by-step explanation: The question requires the student to write an equivalent equation with fewer terms. Nonetheless, this does not prevent applying a mathematically correct approach.

(1) Noah is wrong and the reason is that the initial step is mathematically incorrect. The expression on the right hand side reads 3(4 - 9x), therefore starting with "8 - 3" is very wrong. The right step was to take one side which is 8 and take the other side which is 3(4 - 9x).

(2) Lin is wrong and the reason is that she started inside the parenthesis and this also is mathematically incorrect. The digits inside the parenthesis are "not like terms" and hence calculating 4 - 9x = -5x is very incorrect (the same way you cannot correctly calculate 500 metres minus 200 inches. You must make sure they are both in meters or in inches, that is both must be like terms).

(3) Jada is very correct in using the distributive property and ended up with the only correct solution. The digits on the right hand side of the expression  was solved first and that resulted in -12 + 27x. The reason being that the number outside the parenthesis which is -3, multiplied both digits inside the parenthesis. The minus sign had a major effect, and after simplifying the right hand side the expression now becomes;

8 - 12 + 27x

Since the like terms are 8 and 12, you can simplify further to become

- 4 + 27x OR the expression can be rearranged as 27x - 4

(4) Andre is not correct and the reason is that although he used the distributive property, he made a slight mistake while solving for the right side of the expression. What Andre did was

-3(4 - 9x)

-12 - 27x

Remember that when a negative value multiplies another negative value the answer is positive. Therefore -3 times -9x should have been +27x, just like Jada did as shown above.

From that point onward, his answer would be incorrect.
