CAN ANYONE HELP ME ANSWER THIS ​

Answer:

-7, -2, 4, 5

Step-by-step explanation:

Integers with a dash in the front of them signify a negative. With negative numbers, the higher the value of the accompanying number, the lower value it has as a negative number, so, of course the negative integers would go from the "least" end of the spectrum. Because 7 has a higher positive value than 2, it has a lower negative value, putting -7 on the lower end, following it with the -2. As 5 has a higher positive value than 4, 5 is put on the highest end on the spectrum, with 4 right behind it. With all of these integers settled, we can organize the numbers in the order of -7, then -2, then 4, then 5.

Step-by-step explanation: To write these integers from least to greatest, first draw a number line and graph each of the integers

In the image provided, notice that I've only labeled every other unit on the number line. This  is a labeling technique that we can use to keep things from getting too crowded on the number line.

Now, let's graph our integers.

Integers to the left are always less than integers to to the right. So in this problem, we can see that -7 < -2 < 4 < 5.

Nicole has 25 ten-dollar bills.

To find out how many ten-dollar bills Nicole has, we can divide the total amount of money she has by the value of each bill.

$250 / $10 = 25

Therefore, Nicole has 25 ten-dollar bills.

Answer in detail:

Nicole has $250 in ten-dollar bills. This means that she has 25 groups of $10.

We can divide $250 by $10 to find out how many groups of $10 she has.

$250 / $10 = 25

Therefore, Nicole has 25 ten-dollar bills.

Another way to look at it is this way:

If Nicole has 1 ten-dollar bill, then she has $10.

If Nicole has 2 ten-dollar bills, then she has $20.

If Nicole has 3 ten-dollar bills, then she has $30.

And so on.

So, to find out how many ten-dollar bills Nicole has, we can simply divide the total amount of money she has by the value of each bill.

[tex]\large\boxed{A==\dfrac{3-\sqrt6}{12}\ cm^2}[/tex]

Step-by-step explanation:

The shaded region is the triangle with base b and height h.

[tex]b=BD-CD\to b=\dfrac{\sqrt2}{2}-\dfrac{\sqrt3}{3}=\dfrac{3\sqrt2}{(2)(3)}-\dfrac{2\sqrt3}{(2)(3)}=\dfrac{3\sqrt2-2\sqrt3}{6}\\\\h=AD\to h=\dfrac{\sqrt2}{2}[/tex]

The formula of an area of a triangle:

[tex]A=\dfrac{bh}{2}[/tex]

Substitute:

[tex]A=\dfrac{\frac{3\sqrt2-2\sqrt3}{6}\cdot\frac{\sqrt2}{2}}{2}=\left(\dfrac{3\sqrt2-2\sqrt3}{6}\right)\left(\dfrac{\sqrt2}{2}\right)\left(\dfrac{1}{2}\right)\\\\\text{use the distributive property}\ a(b+c)=ab+ac\\\\=\dfrac{(3\sqrt2-2\sqrt3)(\sqrt2)}{(6)(2)(2)}=\dfrac{(3\sqrt2)(\sqrt2)-(2\sqrt3)(\sqrt2)}{24}\\\\\text{use}\ \sqrt{a}\cdot\sqrt{a}=a\ \text{and}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\=\dfrac{(3)(2)-2\sqrt6}{24}=\dfrac{2(3-\sqrt6)}{24}=\dfrac{3-\sqrt6}{12}[/tex]

Answer:

see explanation

Step-by-step explanation:

The area of the shaded triangle = area of ΔABD - area of ΔADC

A of ΔABD = [tex]\frac{1}{2}[/tex] × AD × BD

A = [tex]\frac{1}{2}[/tex] × [tex]\frac{\sqrt{2} }{2}[/tex] × [tex]\frac{\sqrt{2} }{2}[/tex]

   = [tex]\frac{2}{8}[/tex] = [tex]\frac{1}{4}[/tex]

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

A of ΔACD = [tex]\frac{1}{2}[/tex] × AD × DC

A = [tex]\frac{1}{2}[/tex] × [tex]\frac{\sqrt{2} }{2}[/tex] × [tex]\frac{\sqrt{3} }{3}[/tex]

A = [tex]\frac{\sqrt{6} }{12}[/tex]

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

shaded area = [tex]\frac{1}{4}[/tex] - [tex]\frac{\sqrt{6} }{12}[/tex]

= [tex]\frac{3}{12}[/tex] - [tex]\frac{\sqrt{6} }{12}[/tex] = [tex]\frac{3-\sqrt{6} }{12}[/tex]

Answer:

Y = W = 15 ft.

X= L = 60 ft.

So width is 15 and the length is 60.

Answer: A. 15 feet

Step-by-step explanation:

The formula used to calculate the perimeter of a rectangle is:

[tex]P=2l+2w[/tex]

Where "l" is the lenght of the rectangle and "w" is the width.

You know that the length of this rectangle is 4 times its width. This means that:

[tex]l=4w[/tex]

And you know that the perimeter is 150 feet.

Then, you need to substitute  [tex]l=4w[/tex] and the value of the perimeter into the formula and solve for "w":

[tex]150=2(4w)+2w\\\\150=10w\\\\w=\frac{150}{10}\\\\w=15feet[/tex]

The greatest common factor is 2x

2 can go into both 10 and 12

and so can x

Answer:

for 4x = 20 you have to use the division property of equality divide 20 by 4

for x - 11 = 9 you have to use the addition property of equality add 9 to 11

for 5x + 6x = 22 you have to combine like terms add 5x and 6x to make 11x

for 5(x – 2) = 30 you have to use the distributive property multiply 5 and x; 5 and -2

4x = 20; x = 5

x - 11 = 9; x = 20

5x + 6x = 22; 11x = 22; x = 2

5(x – 2) = 30; 5x - 10 = 30; x = 8

Step-by-step explanation:

I believe the correct answer from the choices listed above is option D. The expression that could be used to determine the average rate at which the object falls during the first 3 seconds of its fall would be  (h(3)-h(0))/3. Average rate can be calculated by the general formula:

Average rate = (change in y-axis) / (change in x-axis)

In this case,

Average rate = (change in height) / (change in time)

The average rate at which the object falls during the first 3 seconds can be calculated using the equation for average rate of change (h(3) - h(0))/3. Using the given function h(t) = 300 - 16t, this comes out to be -16 feet per second.

In this problem, we are given a mathematical model of a falling object, as follows: h(t) = 300 - 16t. Here, the function h(t) represents the height of the object t seconds after it is dropped from a platform 300 feet above the ground.

To determine the average rate at which the object falls during the first 3 seconds, we should use the equation for average rate of change in functions. That is, the change in height divided by the change in time, or (h(3) - h(0))/3.

Let's calculate: h(3) = 300 - 16*3 = 252, and h(0) = 300. Then, the average rate = (252 - 300) / 3 = -48/3 = -16 ft/sec. This indicates that the object falls at an average rate of 16 feet per second during the first three seconds.

Given

f(x)=5x^2+9x-2

Remainder theorem states that when f(x) is divided by x-a then the remainder can be calculated by calculating f(a).

Now Using the remainder theorem to divide 5x^2+9x-2 by x+3 to find the remainder:

f(x)=5x^2+9x-2

Answer:

The simplest form of (a + b - c )(a + b + c ) is a² + 2ab + b² - c²

Step-by-step explanation:

* Lets revise how to multiply two brackets with three terms

∵ (a + b - c)(a + b + c)

- Multiply the first term of the first bracket by the three terms of the

 second bracket

∵ a × a = a²

∵ a × b = ab

∵ a × c = ac

- Then multiply the second term in the first bracket by the three terms

 of the second bracket

∵ b × a = ba

∵ b × b = b²

∴ b × c = bc

- Then multiply the third term term in the first bracket by the three terms

 of the second bracket

∵ -c × a = -ca

∵ -c × b = -cb

∵ -c × c = -c²

- Now add all these terms together

∴ a² + ab + ac + ba + b² + bc + -ca + -cb + -c²

- We have like terms lets add them

∵ ab = ba  , ac = ca , bc = cb

∴ a² + (ab + ba) + (ac + -ca) + (bc + -cb) + b² + -c²

∴ a² + 2ab + 0 + 0 + b² - c²

∴ a² + 2ab + b² - c²

∴ The simplest form of (a + b - c )(a + b + c ) is a² + 2ab + b² - c²

The answer is:

[tex]a^{2} +b^{2} -c^{2} +2ab[/tex]

To solve the problem, we need to remember the distributive property.

The distributive property is defined by the following way:

[tex](a+b)(c+d)=ab+ad+bc+bd[/tex]

Also, we need to remember how to add like terms. The like terms are the terms that share the same variable and the same exponent, for example:

[tex]x+x^{2}+x=x^{2} +2x[/tex]

We were able to add the first and the third term because they share the same variable and the same exponent.

Now, we are given the following expression to simplify:

[tex](a+b-c)(a+b+c)[/tex]

So, applying the distributive property and adding like terms, we have:

[tex](a+b-c)(a+b+c)=(a*a)+(a*b)+(a*c)+(b*a)+(b*b)+(b*c)-(c*a)-(c*b)-(c*c)\\\\(a+b-c)(a+b+c)=a^{2}+ab+ac+ba+b^{2} +bc-ac-bc-c^{2}\\\\(a+b-c)(a+b+c)=a^{2} +b^{2} -c^{2} +2ab[/tex]

Hence, we have that the given expression is equal to:

[tex]a^{2} +b^{2} -c^{2} +2ab[/tex]

The probability of obtaining at random without replacement two gum balls is 3/11.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, A gumball machine contains six yellow gumballs and five orange gumballs.

So, N(Y) = 6 and N(O) = 5 and the number of sample space N(S) = 11.

Therefore, The probability of obtaining at random without replacement two gum balls is,

P(YY) = (6/11)×(6 - 1)/(11 - 1).

P(YY) = (6/11)×(5/10).

P(YY) = 30/110.

P(YY) = 3/11.
