The number of pages in an Algebra 1 book is 99 less than the number of pages in a gemomerty book. Write and solve an equation to find the number n of pages in the geomerty book

Answers

Answer 1

Answer:

n = a + 99

Step-by-step explanation:

Given that :

a = number of pages in algebra book 1

n = number of pages in geometry book

a = n - 99

The number, n of pages in a geometry book is ;

Pages in algebra book = (pages in geometry book - 99)

a = n - 99

a + 99 = n - 99 + 99

a + 99 = n

Two cylinders are shown below. Find the volume of each cylinder. Use 3.14 for pie. Enter your answers rounded to the nearest hundredth.

Answers

Given:

For cylinder P: radius = 4.25 in. and height = 14 in.

For cylinder Q: radius = 7 in. and height = 8.5 in.

To find:

The volume of each cylinder.

Solution:

Volume of a cylinder is

[tex]V=\pi r^2h[/tex]

where, r is radius and h is height. Use 3.14 for [tex]\pi[/tex].

Using the above formula, the volume of cylinder P is

[tex]V_P=(3.14)(4.25)^2(14)[/tex]

[tex]V_P=794.0275[/tex]

[tex]V_P\approx 794.03[/tex]

Using the above formula, the volume of cylinder Q is

[tex]V_Q=(3.14)(7)^2(8.5)[/tex]

[tex]V_Q=1307.81[/tex]

Therefore, the volume of cylinder P is 794.03 sq. in. and volume of cylinder Q is 1307 sq. in.

The volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.

What is the volume of a right circular cylinder?

Suppose that the radius of the considered right circular cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

The given information is

For cylinder P:

radius = 4.25 in. and height = 14 in.

For cylinder Q:

radius = 7 in. and height = 8.5 in.

To find the volume of each cylinder.

The volume of a cylinder

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

where r is radius and h is height.

Using the above formula,

the volume of cylinder P

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

[tex]V = 3.14 \times (4.25)^2 \times 14 \: \rm unit^3\\\\V = 794.03[/tex]

The volume of cylinder Q

[tex]V = \pi r^2 h \: \rm unit^3\\\\V = 3.14 \times 7^2 \times 8.5 \: \rm unit^3\\\\V =1307.81[/tex]

Therefore, the volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.

Which ordered pair represents a solution to both equations

Answers

Answer: (-3,3)

Step-by-step explanation:Answer: (-3,3)

Step-by-step explanation: P= IRT solve for T To solve for T, you must get T on it's own on one side of the equals sign, with all the other terms on the other side. IRT means that I and R are multiplied by T. To get rid of them we must do the opposite of multiply, which is divide. But because this is an equation, anything we do on one side of the equals sign, must be repeated on the other side. So if we divide the right side by IR, we must also divide the left side by IR

What is a logarithm?

The logarithm is exponentiation's opposite function in mathematics.

This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.

Given, A logarithmic equation [tex]ln_ee[/tex], This in exponential form is, [tex]e^? = e[/tex].

We know, [tex]e^? = e[/tex], e to the what power should be e it should be 1.

Therefore, [tex]ln_ee = 1[/tex].

Similarly, [tex]log_{10}10[/tex] is 10 to the what power is 10 we know 10 to the power 1 is 10.

Therefore, [tex]log10[/tex] is 1.

write an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4

Answers

Answer:

We conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:

[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

Step-by-step explanation:

Given the line

y+2x=4

converting into the slope-intercept form y = mx+b where m is the slope

y = -2x+4

comparing with the slope-intercept form

Thus, the slope is: m = -2

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -2

The slope of the new line perpendicular to the given line = – 1/m

                                                                                                = -1/-2 = 1/2

Using the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 1/2 and the point (-3, 5)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=\frac{1}{2}\left(x-\left(-3\right)\right)[/tex]

[tex]y-5=\frac{1}{2}\left(x+3\right)[/tex]

Add 5 to both sides

[tex]y-5+5=\frac{1}{2}\left(x+3\right)+5[/tex]

[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

Therefore, we conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:

[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

This is the equation so far: -2+8+(-6)

Then you would solve the right side 8+(-6) = 2

Now we have -2 + 2 which equals 0.
