Answer:

Density = 8g/cm³

Step-by-step explanation:

Density = Mass/Volume

Given the following

Mass = 960g

Volume = 120cm^3

Substitute

Density = 960g/120cm^3

Density = 8g/cm³

Answer:

n=-1 or n=-4

Step-by-step explanation:

-5/6n + 15/ = -45

/6n + 15/ = 9

square both sides to neutralize absolute value

/6n + 15/^2 = 81

36n^2 + 180n + 225 = 81

divide both sides by 9

4n^2 + 20n + 25 = 9

4n^2 + 20n + 16 = 0

divide both sides by 4

n^2 + 5n + 4 = 0

Factorize

(n + 1)(n + 4) = 0

therefore n = -1 or -4

Answer:

2 3/4

Step-by-step explanation:

2=2

.75= 3/4

Example 75 cents is equal to 3 quarters

[tex]2 \frac{3}{4} [/tex]

Because 2.75 =

[tex] \frac{11}{4} [/tex]

And

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

Answer:

Area = 29284.87 ft²

Step-by-step explanation:

I've drawn a triangle to depict the movement of the dog with the angle and dimensions.

From the attached triangle, we see that the starting point is C, the first point is A and the second point is B.

Let's find the third side from the image using law of cosine.

Thus;

b² = a² + c² - 2ac cos B

Thus;

b² = 180² + 329² - 2(180 × 329)cos 81.5

b² = 32400 + 108241 - 17506.55

b² = 123134.45

b = √123134.45

b = 350.91 ft

We calculate the area of the triangle using heron's formula.

Area = √(p(p − a)(p − b)(p − c))

Where p = (a + b + c)/2 = (180 + 350.91 + 329)/2 = 429.955 ft

Area = √(429.955(429.955 - 180)(429.955 - 350.91)(429.955 - 329)

Area = 29284.886 ft²

To the nearest Hundredth gives;

Area = 29284.87 ft²

Step-by-step explanation:

Answer: Nolan worked 4 hours, and Mia worked 8 hours

Step-by-step explanation:

Step-by-step explanation:

Let x represent the number of hours Nolan worked.

Let y represent the number of hours Mia worked.

Mia worked twice as many hours as Nolan. This means that

y = 2x

Nolan can iron 25 shirts per hour, and Mia can iron 35 shirts per hour. Together, Nolan and Mia ironed 380 shirts between them. This means that

25x + 35y = 380 - - - - - - - - - - - - - -1

Substituting y = 2x into equation 1, it becomes

25x + 35 × 2x = 380

25x + 70x = 380

95x = 380

x = 380/95

x = 4

y = 2x = 2 × 4

y = 8

Answer:

B

Step-by-step explanation:

root three is irrational

Given:

A figure of a circle. A secant and tangent of the given circle.

To find:

The correct equation.

Solution:

According the intersecting tangent secant theorem, the square of tangent is equal to the property of external segment of secant and the measure of the secant.

Using intersecting tangent secant theorem, we get

[tex]6^2=x(x+5)[/tex]

It can be written as

[tex]x(x+5)=6^2[/tex]

The required equation is [tex]x(x+5)=6^2[/tex].

Therefore, the correct option is B.

Answer:

Step-by-step explanation:

1/11 = 0.09090909

2/9 = .2222222222

1/10 is certainly between these two numbers.

1/10 is 0.1 which is larger (just) than 1/11 but a good deal smaller than 2/9

1/20 = 0.05 which is just bigger than 1/11 but much smaller than 2/9. There are many numbers that would fit between 1/11 and 2/9

Answer:

−4+2+10

Step-by-step explanation:

First we add the numbers with no variable or exponent:

−2++3−5+7+4

−2++10−5+4

Then we combine the like terms. When combining like terms, you must find the numbers with the same variable/letter and add them. A number with the variable  cannot be added with the variable . They must be the same variable. Now let's combine the like terms in this problem.

−2++10−5+4

^ As you can see, the variable  does not have a coefficient, so we just use the number 1 as a coefficient. If a variable doesn't have a coefficient, always use 1.

−2−4+10+4

Now we combine the other like terms.

−2−4+10+4

2−4+10

And last, we rearrange the numbers.

To rearrange the numbers, you have to start with the numbers with variables. You must start with the variable that comes first in the alphabet. Then we add the number with no coefficient, just a number by itself. If there's ever an exponent, add the coefficient with an exponent first in the answer.

−4+2+10

Hope this helps! ;)

Answer:

Commutative Property

Step-by-step explanation:

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.

Answer:

Commutative property of addition

I hope this is the answer you're looking for! :)

I just edited it.

We are given two functions.

[tex]f(x)=x-4\\g(x)=-x-2[/tex]

The point that represents the equation [tex]f(x)=g(x)[/tex], will also be the intersection of those two lines, meaning we can set the two equations equal to each other and solve for [tex]x[/tex].

[tex]f(x)=g(x)\\x-4=-x-2\\2x=2\\x=1[/tex]

Now that we are given the x value, we can plug this value back into either equation and solve for the y value.

[tex]f(1)=1-4\\f(1)=-3[/tex]

The point of intersection will be [tex](1,-3)[/tex].

Hope this helps!

Answer:

x=-1

Step-by-step explanation:

x-4=-x-2

x+x=-2+4

2x=-2

x=-1

Rewrite the equation in the slope-intercept form.

3x + y = 3

Subtracting -3x from both sides we get this:

y = -3x + 3

This is just a straight line.

Here, x can be any real number.

When x is any real number, the value of y is also any real number.

A straight line goes on forever in two directions. It really does not matter what number we select for x to find y.

Answer:

Domain is ALL REAL NUMBERS.

Range is ALL REAL NUMBERS.

Your math book may write the answer in interval notation:

Domain is (-00, 00); Range is (-00, 00).

Note:

-00 means negative infinity.

00 means positive infinity.

Still in some math books, the author(s) may decide to use set notation to express ALL REAL NUMBERS for the domain and range.

If so, we can also write the answer this way:

Domain = {x| x = ALL R}, where big R stands for real numbers.

Range = {y| y = ALL R}, where big R stands for real numbers.

Answer:

[tex]d=1.28\times 10^{-6}\ g/cm^3[/tex]

Step-by-step explanation:

The mass of a bag of sugar, m = 1 kg = 0.001 g

Length of bag, l = 9.2 cm

Width of bag, b = 6 cm

Height of the bag, h = 14.1 cm

We need to find the density of the sugar bag.

Density = mass/volume

So,

[tex]d=\dfrac{0.001\ g}{9.2\times 6\times 14.1\ cm^3}\\\\d=1.28\times 10^{-6}\ g/cm^3[/tex]

So, the density of the bag is [tex]1.28\times 10^{-6}\ g/cm^3[/tex].
