∠A and \angle B∠B are complementary angles. If m\angle A=(x+9)^{\circ}∠A=(x+9)

and m\angle B=(7x-15)^{\circ}∠B=(7x−15)

, then find the measure of \angle B∠B.

Answers

Answer:

To find the complement of an angle x, subtract x's measurement from 90 degrees: 90 degrees - x degrees = the measure of x's complementary angle. To find the supplement of an angle y, subtract y's measurement from 180 degrees: 180 degrees - y degrees = the measure of y's supplementary angle.

Which equation represents the statement "One-fourth more than a number is equal to two-thirds?"

Answers

Answer: 1/4 + x = 2/3

Step-by-step explanation:

One fourth is written as 1/4, more than is an addition sign, a number means “x”, is equal means = (equal sign), and two thirds is written as 2/3

Answer:

[tex]x + \frac{1}{4} = \frac{2}{3}[/tex]

Step-by-step explanation:

The statement "One-fourth more than a number is equal to two-thirds" can be expressed in the mathematical form as given below:

Let the number be x.

Therefore, One-fourth more than a number = [tex]x + \frac{1}{4}[/tex]

Now,

One ring in the Stonehenge monument was originally made of 30 stones, each about 6 1/2 feet wide, 3 feet thick, and 13 feet tall. What is the approximate volume of the 17 stones that
remain today?

Answers

Answer: V ≈ 4309.5 ft³

Step-by-step explanation: To get the answer to this word problem all we have to do is multiply height * thickness * width.

First, let's turn 6 [tex]\frac{1}{2}[/tex] into a decimal...

1 ÷ 2 = 0.5

6 [tex]\frac{1}{2}[/tex] = 6.5

6.5 * 3 * 13 = 253.5

Now, we have to multiply it by the remaining amount of stones...

253.5 * 17 = 4309.5

V ≈ 4309.5

15x<30

Answers

Step-by-step explanation:

Basically 15x<30 is saying that 15x is less that 30. So that means x can be any number as long as when multiplied to 15 it has to be less then 30. So they only number available is 1. So 15(1)<30. Im not sure what the question is but X=1

Answer:

x < 2 or (-∞,2)

Step-by-step explanation:

Treat the inequality sign like an = sign at this point. Don't make it more complicated than it really is. So, to figure it out, you first need to divide each side by 15 so you can get x all by itself:

[tex]\frac{15x}{15} < \frac{30}{15}[/tex]

Now we have:

x < [tex]\frac{30}{15}[/tex]

We know (using simple math) that 30 divided by 15 is 2, which gives us:

x < 2.

In interval notation, this would be (-∞,2). [Remember that the parentheses show that the interval does NOT include the specified numbers, which is what < denotes in our equation.] Hope this helped!

1. What are the coordinates of the vertex of the graph? Is it a maximum or minimum?

Answers

Answer:

Hi there!

The correct answer is: (0,1) maximum

Step-by-step explanation:

vertex: the point where the parabola crosses its axis of symmetry.

when the graph is concave down, maximum

when the graph is concave up, minimum

Answer:

Coordinates of the vertex: (0, 1), and it is a maximum.

this corresponds to the second of the listed answer options.

Step-by-step explanation:

Notice that the vertex of the parabola is at the very top of the curve, and corresponds to the maximum value that the coordinate "y" can reach for the parabola (y = 1)

The position of that vertex is exactly at the point where x = 0 and y = 1, so this can be written as:

(0, 1)

Which is the equation in slope-intercept form for the line that passes through (3, 7)
and is perpendicular to 3x - 5y = 8?

Answers

Answer:

[tex]y = - \frac{5}{3} x + 12[/tex]

Step-by-step explanation:

First, rewrite the given equation in the form of y=mx+c.

m is the gradient while c is the y-intercept.

3x-5y=8

5y= 3x -8

[tex]y = \frac{3}{5} x - \frac{8}{5} [/tex]

Thus, the gradient of the given equation is ⅗.

The product of the gradients of perpendicular lines is -1.

(gradient of line)(⅗) = -1

gradient of line= -1 ÷⅗

gradient of line= [tex] - \frac{5}{3} [/tex]

[tex]y = - \frac{5}{3} x + c[/tex]

To find the value of c, substitute a coordinate.

When x=3, y=7,

[tex]7 = - \frac{5}{3} (3) + c[/tex]

7= -5 +c

c= 7+5

c= 12

Hence, the equation of the line is [tex]y = - \frac{5}{3} x + 12[/tex].
