How many one-millimeter cubes do you need to fill a cube that has an edge length of 1 centimeter?

Answer:

m<A = 98.25

m<B = 81.75

m<C = 113

m<D = 113

m<E = 67

Step-by-step explanation:

3x + 12 + 5x - 18 = 180

8x - 6 = 180

8x = 186

x = 23.25

3x + 12

3(23.25) + 12

81.75

5x - 18

5(23.25) - 18

98.25

6y - 5 + 10y - 7 = 180

16y - 12 = 180

16y = 192

y = 12

6y - 5

6(12) - 5

67

10y - 7

10(12) - 7

113

The graph of y = 2x + 3 is shown in attached figure.

What is linear expression?

A linear expression is an algebraic statement where each term is either  constant or variable raised to the first power.

Given that;

The equation is y = 2x + 3

Now, For Complete the table we can calculate as;

For first column;

The value of x = -2

Hence, The value of y is calculated as;

y = 2x + 3

y = 2 × -2 + 3

y = -4 + 3

y = -1

Thus, For first column of table;

x = -2 and y = -1

And, For third column;

The value of x = 0

Hence, The value of y is calculated as;

y = 2x + 3

y = 2 × 0 + 3

y = 0 + 3

y = 3

Thus, For third column of table;

x = 0 and y = 3

And, For fourth column;

The value of x = 1

Hence, The value of y is calculated as;

y = 2x + 3

y = 2 × 1 + 3

y = 2 + 3

y = 5

Thus, For fourth column of table;

x = 1 and y = 5

And, For sixth column;

The value of x = 3

Hence, The value of y is calculated as;

y = 2x + 3

y = 2 × 3 + 3

y = 6 + 3

y = 9

Thus, For sixth column of table;

x = 3 and y = 9

Thus, The complete table is shown in attached figure.

The graph of y = 2x + 3 is shown in attached figure.

Answer:

x > [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

[tex]\frac{5(9-x)}{3+1}<11[/tex]

Add 3 and 1 to get 4.

[tex]\frac{5(9-x)}{4}<11[/tex]

Use the distributive property to multiply 5 by 9−x.

[tex]\frac{45-5x}{4}<11[/tex]

Subtract  45/5 from both sides.

[tex]-\frac{5}{4}x<11-\frac{45}{4}[/tex]

Since 44/4 and 45/4 have the same denominator, subtract them by subtracting their numerators.

[tex]-\frac{5}{4} x<-\frac{1}{4}[/tex]

Multiply both sides by -4/5, the reciprocal of -5/4. Since -5/4 is negative, the inequality direction is changed.

[tex]x>-\frac{1}{4} (-\frac{4}{5} )[/tex]

Multiply -1/4 times -4/5 by multiplying numerator times numerator and denominator times denominator.

[tex]x>\frac{-(-4)}{4 x 5}[/tex]

[tex]x>\frac{1}{5}[/tex]

Answer: the answer is W (-7, -2)

Step-by-step explanation:

Answer:

Hypotenuse: 41 meters, Long leg: 40 meters, Short leg: 9 meters.

Step-by-step explanation:

According to the statement, we have the following information about the lengths of the right triangle:

Hypotenuse

[tex]3\cdot x + 14[/tex]

Long leg

[tex]3\cdot x + 13[/tex]

Short leg

[tex]x[/tex]

By the Pythagoric Theorem, we have the following expression:

[tex](3\cdot x + 14)^{2} = x^{2} + (3\cdot x + 13)^{2}[/tex] (1)

[tex]9\cdot x^{2}+84\cdot x + 196 = x^{2} + 9\cdot x^{2} + 78\cdot x + 169[/tex]

[tex]9\cdot x^{2} + 84\cdot x + 196 = 10\cdot x^{2} + 78\cdot x +169[/tex]

[tex]x^{2} -6\cdot x -27 = 0[/tex]

[tex](x-9)\cdot (x+3) = 0[/tex]

As length is a positive variable by nature, then the only possible solution is [tex]x = 9[/tex]. Lastly, the side lengths of the right triangle are:

Hypotenuse: 41 meters, Long leg: 40 meters, Short leg: 9 meters.

Answer:

The daily rate is: 17500 units per day

Step-by-step explanation:

Given

[tex]R = 1700x - 2x^2[/tex]

[tex]\frac{dx}{dt} = 25[/tex]

Required

Find [tex]\frac{dR}{dt}[/tex] when [tex]x = 250[/tex]

We have:

[tex]R = 1700x - 2x^2[/tex]

Differentiate both sides with respect to time

[tex]\frac{dR}{dt} = 1700\frac{dx}{dt} - 4x\frac{dx}{dt}[/tex]

Factorize

[tex]\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}[/tex]

Substitute: [tex]\frac{dx}{dt} = 25[/tex] and [tex]x = 250[/tex]

[tex]\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}[/tex]

[tex]\frac{dR}{dt} = (1700- 4*250)*25[/tex]

[tex]\frac{dR}{dt} = (1700- 1000)*25[/tex]

[tex]\frac{dR}{dt} = 700*25[/tex]

[tex]\frac{dR}{dt} = 17500[/tex]

From the equation it is clear that it is safe to assume the graph is correctly drawn because (0,-8) is the solution of the equation, and it is the part of the graph.

"A cubic equation is an equation which can be represented in the form a x 3 + b x 2 + c x + d = 0 ax^3+bx^2+cx+d=0 ax3+bx2+cx+d=0, where a , b , c , d a,b,c,d a,b,c,d are complex numbers and a is non-zero. By the fundamental theorem of algebra, cubic equation always has 3 roots, some of which might be equal."

The given equation is 0.5x3 + 3x2 -8[tex]y= 0.5x^3 + 3x^2 -8[/tex]

Replacing in the equation with 0,

we gets

0.5x0+0x3-8=-8

so (0,-8) is the solution of the equation.

Answer:

r=4.5, d=9

Step-by-step explanation:

So, lets go over two things.

#1 - What is Diamater?

Diamater is the distance from one side of a circle to the other.

#2 - What is radius?

Radius is the distance from any side of the circle, to the middle. This is half of the diamater.

In this case, the distance from one side of the circle to the other is 9in.

So the diamater must be 9.

d=9 in

Since we know the radius is half of the diamater, radius is:

9/2

=

4.5 in

So our radius must be 4.5.

r=4.5

This looks like the top answer.

Answer:

will this work or help ?

Step-by-step explanation:

The given equation governs the height versus time of the object. h(0) = 64, so the ground is considered at h = 0. The question is at what time is h = 0? So, set h = 0 and solve for t.

-16t^2 + 48t + 64 = 0

We can divide both sides of this equation by -16 for simpler numbers. We get

t^2 - 3t - 4 = 0

We can factor this equation:

(t - 4)(t + 1) = 0

So, t = 4 and t = -1 are solutions.

But, time must be positive, so t = -1 makes no sense, so we discard it. This leaves

t = 4 sec.

Radius of cylinder = 2 inch (Approx.)

Step-by-step explanation:

Given:

Volume of cylinder = 75.4 in³

Height of cylinder = 6 inches

Find;

Radius of cylinder

Computation:

Volume of cylinder = πr²h

Volume of cylinder = (3.14)r²(6)

75.4 = (18.84)r²

(Radius of cylinder )² = 75.4 / 18.84

(Radius of cylinder )² = 4.002123

(Radius of cylinder) = 2

Radius of cylinder = 2 inch (Approx.)

Answer:

The margin of of error for a 95% confidence interval for the population mean is of 1.39 years.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

The margin of error is:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Population standard deviation of 3 years

This means that [tex]\sigma = 3[/tex]

Sample of 18 voters

This means that [tex]n = 18[/tex]

Margin of error:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]M = 1.96\frac{3}{\sqrt{18}}[/tex]

[tex]M = 1.39[/tex]

The margin of of error for a 95% confidence interval for the population mean is of 1.39 years.
