Answer:
Multiply 15 by 9, then divide by 2.
Step-by-step explanation:
We need to solve the given expression.
[tex]15\div \dfrac{2}{9}[/tex]
We know that, [tex]a\div \dfrac{b}{c}=a\times \dfrac{c}{b}[/tex]
We have,
a = 15, b = 2 and c = 9
So,
[tex]15\div \dfrac{2}{9}=15\times \dfrac{9}{2}\\\\=\dfrac{15\times 9}{2}\\\\=\dfrac{135}{2}\\\\=67.5[/tex]
So, the steps are "Multiply 15 by 9, then divide by 2".
the poles for a tent form vertices of a regular decagon. when the poles are properly positioned, what is the measure of the angle formed at a corner of the tent. ( n - 2 ) × 180
Answer:
Each Interior Polygon angle = 180 - [ 360 / number of sides]
Each Angle = 180 - [ 360 / 10]
Each Angle = 180 - 36
Each Angle = 144 degrees

Explanation:
(a) Keep in mind the meaning of the variables:
x = PS4 units soldy = X.box 1 units soldWith these definitions in mind, we can examine the constraints.
x ≥ 0 . . . . . we cannot sell a negative number of PS4 units
y ≥ 0 . . . . . we cannot sell a negative number of X.box 1 units
y ≥ 5 . . . . . we intend to sell at least 5 X.box 1 units
y ≤ 10 . . . . we cannot sell more than 10 X.box 1 units
x + y ≤ 10 . . . . . we can sell at most 10 units total
(Please note that the constraints y ≥ 0 and y ≤ 10 are redundant to other more restrictive conditions.)
__
(b) The objective function tells us the total profit:
P(x, y) = 100x + 80y
__
(c) Juan's goal: P(2, 7) = 100(2) +80(7) = 200 +560 = 760
Justin's goal: P(4, 5) = 100(4) +80(5) = 400 +400 = 800
Meeting Justin's goal would result in more profit.
__
(d) It is not possible to sell a negative number of units*, so negative values for the variables do not make any sense. (This is consistent with the x≥0, y≥0 constraints above.)
_____
* Some linear programming problems plan for a certain number of returned items. Those could be considered to be negative sales.

Graph the logarithmic function f(x) = log2(x - 1) + 2.
anyone know this pls help
Answer:
I graphed it for you in the image below.
Step-by-step explanation:
Graph the logarithmic function f(x) = log2(x - 1) + 2 is attached below.
What is a function?The function is referred to as a particular kind of relationship, every value in the domain is associated with exactly one value in the range. They have a set perimeter and territory.
It is given that the logarithmic function is, f(x) = log2(x - 1) + 2.
The first step in graphing a logarithmic function is to locate some points on the exponential f. (x). The graph will look better as we plot more points, and we can flip the x and y values to get points on the opposite axis. locate the asymptote. The following logarithmic functions can be graphed. Specify the domain and the range.
Thus, the graph is attached below.

two triangles are similar the lengths of the sides of one of the triangels 2 times that of corrsponding sides of the other. thearea of the smaller triangle is 25sq.cm.find the area of the larger triangle.
plz step
Answer:
100 sq. cm
Step-by-step explanation:
The scale factor from the smaller triangle to the larger triangle is 2.
The ratio of the areas is 2² = 4
4 * 25 sq. cm = 100 sq. cm
Find the area of the figure.
10 cm
15 cm
20 cm
20 cm
The area of the figure is
square centimeters.
Answer:
10 x 15 = 150
Area of trapezoid:
10 + 20 = 30
30 x 5 = 150
20 - 15 = 5
150 divided by 2 ( x 1/2) = 75
75 + 150 = 225 square cm
Formula of a trapezoid:
B1(base1) + B2(base2) x H (Height) x 1/2 (basically dividing by 2)

easy algebra question below first correct answer gets brainliest
Answer:
x = 2 and -4
Step-by-step explanation:
(x + 1)² = 9
First, take the square root of both sides. This will eliminate the square on the left side.
(x + 1) = √9
Note that √9 can be 3 or -3.
Let's write out both possibilities.
(x + 1) = 3
(x + 1) = -3
Solve.
(x + 1) = 3
[subtract 1 from both sides]
x = 2
--
(x + 1) = -3
[subtract 1 from both sides]
x = -4
Your answers are 2 and -4.
Let's check our answers by plugging in the values back into the original equation.
(x + 1)² = 9
(2 + 1)² = 9
(3)² = 9
9 = 9
That solution is correct.
(x + 1)² = 9
(-4 + 1)² = 9
(-3)² = 9
9 = 9
That solution is also correct.
Your answer is correct.
Hope this helps!
the measure of a base isosceles triangle is 43? what is the measure of the vertex angle
Answer:
The vertex angle is 94 degrees
Step-by-step explanation:
Let the vertex angle be x
Mathematically, the base angles of an isosceles triangle are the same
So if one of the base angles is 43 degrees, then the other base angle would be 43 degrees too
Mathematically, the sum of angles in a triangle is 180 degrees
Thus;
43 + 43 + x = 180
x = 180-86
x = 94 degrees

The domain of the function is x
Answer: [tex]t<444.44[/tex]
Step-by-step explanation:
Given
Texting bill is given by [tex]c(t)=0.09t[/tex]
Spending must be less than [tex]\$40\ \text{per month}[/tex]
So, text billing must be less than $40
[tex]\therefore 0.09t<40\\\\\Rightarrow t<\dfrac{40}{0.09}\\\\\Rightarrow t<444.44[/tex]

A cylinder has a volume of 791.28 cubic centimeters. The height of the cylinder is 7.0 inches. Calculate the radius of the cylinder. Use 3.14 for π.
Answer:
The radius is 6
[tex] \sqrt{v \div \pi \times h =} [/tex]
=791.28/3.14×7.0
=
[tex] \sqrt{36} [/tex]
=6
The radius of cylinder is 3.764 cm.
What is volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Finding an object's volume can help us determine how much material is needed to fill it, such as how much water is needed to fill a bottle, aquarium, or water tank.
Given volume of cylinder = 791.28 cm³
height = 7.0 inches
so, 1 inch = 2.54 cm
7 inch = 2.54 x 7 = 17.78 cm
height = h = 17.78 cm
volume of cylinder = πr²h
where r = radius
V = πr²h
791.28 = 3.14(17.78)r²
r² = 791.28/55.8292
r² = 14.1732
r = √14.17732
r = 3.764 cm
Hence the radius is 3.764 cm.
