Answer:

2; 10

Step-by-step explanation:

12/2 = 6

[tex](x+6)^{2}[/tex] = [tex]x^{2}[/tex] +12x + 36

   [tex]x^{2}[/tex] +12x + 20

-   [tex]x^{2}[/tex] +12x + 36

    0 + 0  - 16

[tex](x+6)^{2}[/tex] - 16 = 0

[tex](x+6)^{2}[/tex] = 16

x + 6 = [tex]\sqrt{16}[/tex]

x = -4 + 6 = 2

x = 4 + 6 = 10

Answer:

One of the benefits of Cavalieri's principle is that it allows us to determine the volume of an oblique prism (or oblique cylinder). When dealing with two prisms (or two cylinders), if the base areas are equal and the heights are equal, then the volume is V = Bh regardless of the overall shape.

Answer:

i think it would be around 34 feet

Step-by-step explanation:

the bottom is cut in half and each half is 8 and 1/2 feet so if you add 8 and 1/2 + 8 and 1/2 you would get 17 and then the top is rounded so you would just add 17 and 27 together to get the distance around.

11.7

Formula: a^2 + b^2 = c^2

so substitute the numbers like this:

10^2 + 6^2 = c^2

both 10^2 and 6^2 are perfect squares:

10 × 10= 100 and 6 × 6= 36

100 + 36= c^2

add:

100 + 36 =

136 = c^2

now in order to get rid of the squared, you put it into a radical:

√136 = √c^2

note: whatever you do on one side, you do to the other

it's easier to use the calculator for this so put √136 and you're gonna get 11.66

since it's asking you to round it to the nearest tenth:

11.66 = 11.7

Step-by-step explanation:

Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.

Answer:

In one hour Stephanie earns $1.50 more than Marco

Step-by-step explanation:

w=9h

H is a variable

9×hour= wage

9×15= $135

9×18= $162

157.50-135=$22.50

189-162=$27

27-22.50=4.50

Now cause its per hour we know she earns $4.50 more in 3 hours.

4.50÷3=$1.50

Step-by-step explanation:

10w¹⁰ - 19w⁹ + 6w⁸

= w⁸(10w² - 19w + 6)

= w⁸(2w-3)(5w-2)

The value of the equation after factorization is A = w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 10w¹⁰ - 19w⁹ + 6w⁸   be equation (1)

Now , on factorizing the equation , we get

Taking the common factor as w⁸ , we get

A = w⁸ ( 10w² - 19w + 6 )

On further simplification , we get

A = w⁸ ( 10w² - 15w - 4w + 6 )

Now , on factorizing the equation , we get

A = w⁸ ( 5w ( 2w - 3 ) - 2 ( 2w - 3 ) )

And , the equation will be

A = w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )

Therefore , the value of A is w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )

Hence , the equation is A = w⁸ ( ( 5w - 2 ) ( 2w - 3 ) )

Answer:

9 times as many as 3 is 27.

Step-by-step explanation:

Answer:

You first plot the point (0,2), then when the x-value of the graph increases by 3, decrease the y-value of the graph by 1, and when the x-value o the graph decreases by 3, increase the y-value of the graph by 1.

Step-by-step explanation:

The equation would be [tex]y = -\frac{1}{3}x+2[/tex]. To graph it, you first need to find the y-intercept, which is the coordinate on the line when the x-value equals 0. If x = 0, [tex]y = -\frac{1}{3}x+2[/tex] would become [tex]y = 2[/tex] since anything multiplied by 0 would become 0. Now you've located the y-intercept, which is (0, 2). The slope of a line is the coefficient of the variable x. Since the slope is a negative number, the line will go downwards as it increases its x-value and goes upward as it decreases its x-value. A slope of [tex]-\frac{1}{3}[/tex] would mean that when the x-value increases by 3, the line's y-value will decrease by 1. And when the x-value decreases by 3, the line's y-value will increase by 1. An x-value increase of 6 would be a decrease of 2, and so on. Two other obvious points on the line would be (6,0) and (3, 1).

Answer:

  a.  all points are part of the solution set

  b.  no points are in the solution set

Step-by-step explanation:

Graphs of the two systems of inequalities are attached.

a) The red area on the graph is the solution. The two inequalities can be combined to one compound inequality:

  x -1 < y < -1/2x +2

The two boundary lines intersect at x-1 = -1/2x +2   ⇒   x = 2, so there are no points in the solution set with x-values of 2 or greater.

All of the given points are in the solution set.

__

b) The green area of the graph is the solution. Solving each inequality for y gives ...

  x -2y ≥ 4  ⇒  1/2x -2 ≥ y

  2x -y ≥ -1  ⇒  2x +1 ≥ y

The allowed values of y must be less than or equal to the minimum of these limits. The limits have the same value at 1/2x -2 = 2x +1   ⇒   x = -2, so the solution set is the area below and right of that intersection point of the two boundary lines.

None of the given points are in the solution set.

Answer:

8 dimes and 14 quarters.

Step-by-step explanation:

d and q are the number of dimes and quarters, respectively.

"22 coins, all dimes and quarters"

d+q = 22

d = 22-q

"total value is $4.30"

0.10d + 0.25q = 4.30

substitution

0.10(22-q) + 0.25q = 4.30

2.2 + 0.15q = 4.30

q = 14

d = 22-q = 8

8 dimes and 14 quarters.
