Explain It Adam made 19 paper cranes Monday and 8 more Tuesday. He gave 9 friends an equal number of cranes. How many cranes did each friend received? Explain how you found your answer.

Answers

Answer 1

Answer:

Answer: Each friend received 3 paper cranes.

Step-by-step explanation:

Given : Number of paper cranes made by Adam on Monday = 19

Number of paper cranes made by Adam on Tuesday = 8

Total number of paper cranes made by Adam = (Number of paper cranes made on Monday) + (Number of paper cranes made on Tuesday )

= 19+8

= 27

Now , all paper cranes are equally divided into 9 friends , the number of paper cranes received by each friend = (Total number of paper cranes ) ÷ (9)

= (27)÷ (9)

= 3

Hence, each friend received 3 paper cranes.

Answer 2

Answer: he made 19 paper cranes on Monday & 8 more on tuesday
total cranes made = 19 + 8 = 27
number of cranes he give to each of his 9 friends = 27/9 = 3 cranes

Answers

Answer:

C. $16x^2+24xy+9y^2$

Step-by-step explanation:

We have been given 4 expressions and we are asked to choose the expression that is a perfect square trinomial.

We know that a perfect square trinomial is in form: $a^2+2ab+b^2$ .

Upon looking at our given choices we can see that option C is the correct choice as we can write as:

$16x^2+24xy+9y^2=(4x)^2+2(4x\cdot 3y)+(3y)^2$

$16x^2+24xy+9y^2=(4x)^2+2(12xy)+(3y)^2$

$16x^2+24xy+9y^2=(4x)^2+24xy+(3y)^2$

Therefore, option C is the correct choice.

A perfect square trinomial is found in the expression where both the leading coefficients and the constant are both perfect squares. That only is the case with the third choice above. 16 is a perfect square of 4 times 4, and 9 is a perfect square of 3 times 3. We need to set it up into its perfect square factors and FOIL to make sure, so let's do that. Not only is 16 a perfect square in that first term, but so is x-squared. Not only is 9 a perfect square in the third term, but so is y-squared. So our factors will look like this:

(4x + 3y)(4x + 3y). FOIL that out to see that it does in fact give you back the polynomial that is the third choice down.

The box plots below show the reading levels estimates of the top ten novels selected by a survey of young adults in 2012 and 2015.

Answers

Final answer:

A boxplot is a graph that displays the middle 50 percent of a data set, using the minimumvalue, first quartile, median, third quartile, and maximumvalue.

Explanation:

A boxplot is a type of graph that visually displays the middle 50 percent of a data set. It is constructed using the minimum value, first quartile, median, third quartile, and maximum value.

The firstquartile is the median of the lower half of the data, while the third quartile is the median of the upper half.

The whiskers extend from the box to the minimum and maximum values within a certain range. The range can vary, but it's often defined as 1.5 times the IQR. Data points beyond the whiskers are considered outliers and are typically marked individually.

Find the zeros of the function by rewriting in intercept form.Y=2X^2-4x

y=2C^2-11X-21

I need the answer and the work please.

Answers

The intercept form is $y=a(x-p)(x-q)$ where p, q - the zeroes of a function.

1.
$y=2x^2-4x \ny=2x(x-2) \ny=2(x-0)(x-2) \n\hbox{the zeroes - }\boxed{x=0 \ and \ x=2}$

2.
$y=2x^2-11x-21 \ny=2x^2-14x+3x-21 \ny=2x(x-7)+3(x-7) \ny=(2x+3)(x-7) \ny=2(x+(3)/(2))(x-7) \n y=2(x-(-(3)/(2)))(x-7) \n\hbox{the zeroes - }\boxed{x=-(3)/(2) \ and \ x=7}$

The graph shows two lines, A and B:A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6. Another straight line labeled B joins the ordered pair 0, 0 and the ordered pair 5, 5.

Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?

A (0, 6) is the solution to both lines A and B.
B(0, 6) is the solution to line B but not to line
C(2, 2) is the solution to both lines A and B.
D (2, 2) is the solution to line A but not to line

Answers

The correct answer for the question that is being presented above is this one: "A (0, 6) is the solution to both lines A and B." The statement that is correct about the solution to the system of equations for lines A and B is that (0, 6) is the solution to both lines A and B.

Answer:

C(2, 2) is the solution to both lines A and B.

Step-by-step explanation:

Line A is given as:

A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6.

We know that the equation of a line passing through (a,b) and (c,d) is calculated as:

$y-b=(d-b)/(c-a)* (x-a)$

Hence, the equation of line is:

$y-0=(6-0)/(0-3)* (x-3)\n\ny=(6)/(-3)* (x-3)\n\ny=-2* (x-3)\n\ny=-2x+6$

Hence, equation of line A is:

$y=-2x+6$

Similarly B is a line passing through (0,0) and (5,5).

Hence, the equation of line B is:

$y=x$

So, from the graph we observe that, the point of intersection of the two lines is (2,2).

Thus, option C is correct.
