20, 18,14,24 are not perfect squares.

Answer:

24, 14, 18, 20

Step-by-step explanation:

A perfect square is a number that can be expressed as the product of two equal integers. Numbers 24, 14, 18, and 20 are not products of any equal numbers. The rest are.

Answer:

Step-by-step explanation:

The intersection is when both functions have same coordinates

Substitute to get

The y- coordinate is

So the intersection point is (1, 14)

Answer:

(1, 14)

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=-2x+16\\g(x)=4x+10\end{cases}[/tex]

Substitute the function notation for y to create a system of equations:

[tex]\begin{cases}y=-2x+16\\y=4x+10\end{cases}[/tex]

To find the points of intersection of the given functions, solve the system of equations.

Multiply the first equation (function f(x)) by 2:

[tex]\implies 2y=-4x+32[/tex]

Add this to the second equation (function g(x)) to eliminate x:

[tex]\begin{array}{r l}4x+10 & = y\\+ \quad -4x+32 & = 2y\\\cline{1-2} 42 & = 3y\end{array}[/tex]

Solve for y:

[tex]\implies 3y=42[/tex]

[tex]\implies y=14[/tex]

Substitute the found value of y into one of the equations and solve for x:

[tex]\implies 4x+10=14[/tex]

[tex]\implies 4x=4[/tex]

[tex]\implies x=1[/tex]

Therefore, the point of intersection of the given functions is (1, 14).

Answer: C

Step-by-step explanation:

Step-by-step explanation:

Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX

"K" is the constant of proportionality and must be determined from the initial information.

If Y = 45 when X=140 means 45 = 140K

K = 45/140 = 0.32

Now that we know the value of K, we can use it to calculate the value of Y when X=70

Y = (0.32)(70) = 22.4

Answer:

94 minutes

Step-by-step explanation:

To get to 9:00, we add 6 minutes. From 9 to 10, there's 60 minutes. From 10 to 10:28, there's 28 minutes.

If we add them all together we get 94 minutes or 1 hour and 34 minutes.

Answer:

Your Answer is 11 inches by 2 inches

Step-by-step explanation:

Area of Rectangle: Area = Length * Width

Given information:

Put that into the Formula.

Area = Length * Width

22 in^2 = (2x - 1) * (x - 4)

Solve.

22 in^2 = (2x - 1) * (x - 4)

[tex]22 = (2x^2 - 9x + 4)\\2x^2 - 9x - 18 = 0[/tex]

Factor it.

(2x^2 - 9x - 18) = 0

(2x + 3)(x-6) = 0

[tex]x=-\frac{3}{2} ,6[/tex]

Plug that into the Length and Width to find the actually Length and Width.

Length:

[tex]2x - 1\\2*-\frac{3}{2}-1\\ -3-1\\-4\\[/tex]

Width:

[tex]x - 4\\-\frac{3}{2}-4\\ -\frac{11}{2}[/tex]

Area = Length * Width

Area = - 4* -11/2

Area = 22

Length:

[tex]2x - 1\\2*6-1\\ 12-1\\11\\[/tex]

Width:

[tex]x- 4\\6-4\\ 2[/tex]

Area = Length * Width

Area = 11 * 2

Area = 22 in^2

Using proportions, it is found that each person consumes 3.57 times as many rice in Brazil and they do in the United States.

A proportion is a fraction of a total amount.

In this problem, we have that:

Hence, the rate between the consumption in Brazil and in the United States is given by:

[tex]r = \frac{5 \times 10^4}{1.4 \times 10^4} = 3.57[/tex]

Each person consumes 3.57 times as many rice in Brazil and they do in the United States.

Answer: Choice C

7*r+7*4-3

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

Reason:

We use the distributive property to go from 7(r+4) to 7*r+7*4

Multiply the outer 7 by each term inside.

Then the -3 tags along without any changes to it

So we go from 7(r+4) - 3 to 7*r+7*4 - 3

This can be simplified further to 7r+25, but your teacher has chosen not to simplify at this time.

Answer:

112 degrees

Step-by-step explanation:

180-68=112

Since they are supplementary they form a straight angle, or 180 degrees so the angle AED is 112

Answer:

112

Step-by-step explanation:

∠AED and 68 are Linear pair angles.

That is their sum will be equal to 180,

∠AED + 68 = 180

∠AED = 180 - 68

∠AED = 112

The fraction of books which had 200 or fewer pages is given by A = 1/2

A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary.

A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.

It is used when showing the distribution of data points across a selected measure and if the box in a box plot is stretched in one direction or the other, then the data is skewed in that direction.

Given data ,

Isabelle kept track of the number of pages in each book she read last summer

Now , let the box plot be represented as A

Now , the first and third quartile along with the median is given below ;

So , the fraction of books which had 200 or fewer books is given by A = 1/2

Hence , the box plot is solved and the fraction is A = 1/2

A statistical question Len could ask is "How tall is a red kangaroo?"

Step-by-step explanation:

A statistical question is something that we can ask and test hypotheses about using collected data. There will not be a specific answer, but rather multiple answers and we can average them in a sampling distribution.

Let's examine each question:

"How tall is a red kangaroo?"

"Are there red kangaroos in Asia?"

"Are red kangaroos an endangered species?"

What is the tallest red kangaroo ever recorded?"
