Answer:

561

Step-by-step explanation:

168/3=56 (10 percent of armandos pull ups)

56 x 10 = 560 (100 percent of armandos pull ups)

Now it is equal. We are looking for greater than armando. You would need 561 pull ups to have more

The inverse property of multiplication refers to multiplying a number with it's reciprocal. This is applied while transforming from division to multiplication as division is the inverse of multiplication.

Associative property of multiplication is applied while multiplying several values, Hence rearranging the terms will still give same answer.

This property has it that the order of the multiplication do not matter, hence multiplication can start with any order.

This property refers to multiplication of a value with one, such multiplication usually return same value as the product.

Option D is the correct answer.

Triangle Inequality Theorem states that the sum of two side lengths of a triangle is always greater than the third side.

If this is true for all three combinations of three combinations of side lengths.

i.e., a + b > c , b + c > a and c + a > b then the length form a triangle.

(A) 10 + 11 = 21 > 20

And 11 + 20 =31 > 10

And, 20 + 10 = 30 > 11

So, it forms a triangle

(B) 14 + 16 = 30 >28

And 16 + 28 = 44 >14

And 28 + 14 = 42 > 16

So, it forms a triangle

(C) 35 + 45 = 80 > 75

And 45 + 75 = 120 > 35

And 75 + 35 = 110 > 45

So, it forms a triangle

(D) 41 + 55 = 96 < 98

It does not form a triangle

because sum of two sides lengths is less than the third side length.

Hence, Option D is the correct answer

The ratio of trick-or-treaters who were not dressed as snow white last Halloween is 5/9

Ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other.

It can be expressed in different ways:

1) Use the ":" to separate the values : a : b

2) Use the word "to" : a to b

3) Write it in fraction: a / b

On the other hand, proportion is the equality of two or more ratios.

example: a : b = c : d

If four out of every nine trick-or-treaters that came to your house last Halloween were dressed as snow white, then the rest were not dressed as snow white.

9 - 4 = 5

If five out every nine trick-or-treaters that came to your house last Halloween were not dressed as snow white, we can express the ratio as

The direct variation equation between x and y is 4x = y.

Here, we are given that x and y are in direct variation. In other words, this means that x and y are directly proportional to each other.

Thus, if k is a constant term, then the relation between x and y can be represented as-

x = ky

Now, we are given that if y = 12, x = 3

⇒ 3 = 12k

12k = 3

k= 3/12

k= 1/4

Thus, we found the value of k, the relation will become-

x = y/4

The 32th term of the arithmetic sequence AP is found to be -146.

An arithmetic progression (AP) is a succession in which each successive term has the same distinctions.

Now, to answer the question;

The given sequence of the numbers is-

9,4,-1,-6,-11, ...........

There are total 32 terms in the series for which we have to find 32nd number.

Let the first term be 'a₁' = 9.

Let the second term be 'a₂' = 4

Let the third term be 'a₃' = -1.

The common difference of between the two consecutive terms is equal of an AP is 'd'.

d = a₂ - a₁  

Substitute the values in the above equation;

d = 4 - 9

d = -5

Now, the 32th term is calculated by the nth term formula;

Now, substitute all the value in the formula,

a₃₂ = a + (n - 1) d

a₃₂ = 9 + (32 - 1)(-5)

a₃₂ = 9 - 160 + 5

a₃₂ = -146.

Therefore, the 32nd term of the arithmetic sequence is estimated as -146.

Answer:

2(x + 6) = 38

Step-by-step explanation:

First, we choose a variable to represent the unknown number.

1. Let x = the unknown number.

Then, we translate the sentence into an equation using the variable we chose.

"Twice the sum of six and a number is 38."

We do it piece by piece:

"the sum of six and a number":                        x + 6

"Twice the sum of six and a number":              2(x + 6)

"Twice the sum of six and a number is 38.":    2(x + 6) = 38

Now we have an equation that represents the sentence.

2(x + 6) = 38

The local grocery store mixed 13 oz of planters mixed nuts with 19.5 oz of emerald mixed nuts to get 32.5 oz bags of mixed nuts that contain 56% peanuts.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the amount of planters mixed nuts and y represent the amount of emerald mixed nuts, hence:

x + y = 32.5   (1)

The estimated thickness of a sheet of paper using a single digit and a power of 10 as required in the task content is; 1 × 10-³.

It follows from the task content that the estimated thickness of paper such that it is written using a single digit and a power of 10 as required in the task content is to be determined.

Given;

Thickness of sheet = 0.0013.

By rounding to one significant digit; the digit is considered and rounded down to zero which is added to 1 so that we have;

= 0.001.

On this note, since the number, 0.001 can be written via the laws of indices as;

= (1/1000)

= 1/10³

Answer:

B.  -2  <  x  <  4

Step-by-step explanation:

The function is (x +2)/(x-4) and we are asked to determine the x interval when the inequality (x +2)/(x-4) < 0 is satisfied

1. Find the critical points

The critical points are

x = - 2 when the numerator becomes -2 + 2 = 0, and f(x) = 0

and

x = 4 when the denominator becomes 4 - 4 = 0 and (x + 2)/0 is undefined

So critical points are -2 and 4

2. Use these critical points to divide the number line into intervals
The intervals are -∞ < x < -2, -2 < x < 4 and 4 < x < ∞
these can be re-written as x < -2, -2 < x < -4 and x > 4

3. For each  of these intervals take a test point and see if it satisfies that inequality
(a) -∞ < x < -2    Take x = -3 which is less than -2
We get f(-3) =  (-3 + 2)/(-3 -4) = -1/-7 which is + 1/7 and does not satisfy the (x+2)/(x-4) < 0 inequality.

So we can discard this interval
(b) For interval -2 < x < 4, Let's take x = 0
(0+2)/(0-4) = 2/(-4) = -1/2 = -0.5 which does satisfy the inequality
(x+2)/(x-4) <0, so this is a valid interval

(c) For interval x > 4, take x = 5
(x+2)/(x-4 ) = (5 + 2)/(5-4) = 7/1 = 7 and does not satisfy (x+2)/(x-4 ) < 0

So the interval which satisfies the inequality is -2 < x < 4

Answer:

===============================================

Reason:

In the first graph, it is possible to draw a single vertical line through more than one point on the blue graph. For instance, draw a vertical line through 1 on the x axis.

Because this happens, we consider the graph to "fail the vertical line test". This leads to the graph not being a function.

A function is only possible if any input in the domain leads to exactly one and only one output.

The input x = 1 leads to multiple outputs y = 3 and y = -3 simultaneously.

---------------------------

On the other hand, the second graph doesn't have this issue happening. It's impossible to draw a single vertical line through more than one point on the blue graph.

Therefore, this graph passes the vertical line test and it is a function. Whatever x input you pick, it leads to one y output only.

Based on the scale of the drawing, and the actual width, the width of a park in a drawing would be 14 inches.

A single inch of the width of a park in a drawing, is 5 yards of the width of the actual park.

This means that a single inch equates to 5 yards.

If there were therefore 70 yards in the actual park, the width of the drawing is:
= 70 / 5
