Answer:
bx = - 3
Step-by-step explanation:
- 2(bx - 5) = 16
- 2bx + 10 = 16
- 2bx + 10 - 10 = 16 - 10
- 2bx = 6
- 2bx ÷ - 2 = 6 ÷ - 2
bx = - 3

Given:
A figure of a right angle triangle.
To find:
The length of BC.
Solution:
In a right angle triangle,
[tex]\tan \theta =\dfrac{Perpendicular}{Base}[/tex]
In the given triangle,
[tex]\tan A =\dfrac{BC}{AC}[/tex]
[tex]\tan 23^\circ =\dfrac{BC}{6}[/tex]
[tex]0.42447\times 6 =BC[/tex]
[tex]2.54682 =BC[/tex]
Approximate the value to the nearest hundredth.
[tex]BC\approx 2.55[/tex]
Therefore, the measure of side BC is 2.55 units.

I made a mistake while solving the inequality below. What mistake did I make? Explain what I should’ve done instead.
Answer:
Mistakes:
Used addition
Didn't flip inequality form
Corrections:
Divide each term
Instead of a positive value it should be negative
flip the direction of the inequality form

Which value of x is in the domain of f(t) = squared x - 7
O A. x= 8
O B. x = 0
C. x= -3
O D. x = 6
SUBMIT
Given:
The given function is:
[tex]f(x)=\sqrt{x-7}[/tex]
To find:
The value of x that is in the domain.
Solution:
Domain is the set of input values.
We have,
[tex]f(x)=\sqrt{x-7}[/tex]
We know that the square root is defined for non negative values. So,
[tex]x-7\geq 0[/tex]
[tex]x\geq 0+7[/tex]
[tex]x\geq 7[/tex]
Thus, the domain of the given function is all real number that are greater than or equal to 7.
In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So, [tex]x=8[/tex] is in the domain of the given function.
Therefore, the correct option is A.
pls help me solve any of these pls show how you got the answer to the question you chose

Figure 1 shows a paperweight made from a hollow hemisphere and a hollow cone. The paperweight contains sand so that the sand exactly fills the hemisphere. The radius of the hemisphere is equal to the radius of the base of the cone. The height of the cone is 15cm and the volume of the cone is 180π cm3 Figure 2 below shows the paperweight after it has been turned upside down. Diagram NOT accurately drawn h cm Figure 2 The height of the sand in the cone is h cm. Find, to 3 significant figures, the value of h.
Answer:
13.95 cm
Step-by-step explanation:
the volume of the cone =
⅓× π r². h = 180 π
⅓×π r²×15 = 180 π
(eliminate π)
=> 5r² = 180
r² = 180/5 = 36
r=√36 = 6 cm
the volume of the sand = ½×4/3 π r³
= ⅔× π ×6³ = 144π cm³
the ratio of the volume :
144π/180π = 0.8
so the value of h = ³√0.8 x 15 = 0.93× 15
= 13.95 cm
Solve for w:

what is the median of 4, 4, 7, 13, 12, 9
Answer:
8.11
Step-by-step explanation:
4+4+7+13+12+9 = 49
divide that by 6
========================================================
Explanation:
Sort the data set to go from {4,4,7,13,12,9} to {4,4,7,9,12,13}
Next, cross off the first and last items to get this smaller set: {4,7,9,12}
Repeat the last step to get this even smaller set: {7,9}
We can see that 7 & 9 are tied for the middle most positions. Add them up and divide by 2 to find the midpoint
(7+9)/2 = 16/2 = 8
The median is 8
The resulting row 1 entries are:
7.12
7.10
7,9
Answer:
OPTION C is the correct answer
7,9
Answer:
option 3 is correct

Answer:
Each fraction of the shape is 1/3 the whole shape. So the answer is B.
Answer:
I think C
Step-by-step explanation:
1. Provide an example of a variable term.
2. Provide an example of a constant term.
3. When looking at an expression and/or equation, how can we tell that we need to distribute?
4. When solving an equation, if you get the solution, x=0, how many solutions to the equation are there?
(One solution, no solution, or infinite solutions)
5. When solving an equation, if you get 5 = 11, what does this mean? (One solution, no solution, or infinite
solutions)
6. When solving an equation, if you get 5 = 5, what does this mean? (One solution, no solution, or infinite
solutions)
Answer:
Step-by-step explanation:
1) a variable term contains a variable. If x is a variable
5x is an example of a variable therm
2) a constant therm is not a variable
3 is an example
3) for example when a number multiply a sum or a difference between a constant and a variable
Example:
2(x-3) = 5(x+4)
4) one solution: only if x is equal to 0 the equation is true
5) no solution: the equation can’t be true for ever value of the variable
6) infinite solutions: the equation is ever true for every value of the variable

Find the average rate of change of a function that contains the points (-2,3) and (2,5)
Answer: [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Rate of change are typically found using [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1} }[/tex].
[tex](x_{1}, y_{1}) = (-2, 3)\\(x_{2}, y_{2}) = (2, 5)\\\\\frac{5-3}{2-(-2)} =\frac{2}{2+2} =\frac{2}{4} =\frac{1}{2}[/tex]
Therefore, the rate of change(aka slope) is [tex]\frac{1}{2}[/tex].
When solving the equation 6x - 8 = 12, the first step is to move the
constant, 8, to the right side by adding 8 to both sides. What is the
equation after step one?*
6x - 8 = 12 + 8
14x - 8 = 20
6x = 12 + 8
6x = 20
Answer:
6x= 12+8

Money in a bank triples every 9 years. If $100 is deposited today, what will it's value be after 36 years?
Answer:
[tex]\$8,100[/tex]
Step-by-step explanation:
We can denote this increase with the function [tex]y=3^x\cdot 100[/tex], where [tex]y[/tex] is value after [tex]\frac{x}{9}[/tex] years.
Substituting [tex]x=36[/tex], we get:
[tex]3^4\cdot 100=\boxed{\$8,100}[/tex]
Answer:
8,100
Step-by-step explanation:
The first 9 years would be 300, then 18 years would be 900, and 27 years it would be 2,700, and finally after 36 years it would be 8,100.

Answer:
a ≈ 14.39
Step-by-step explanation:
7² + a² = 16²
49 + a² = 256
49 - 49 + a² = 256 - 49
a² = 207
√a² = √207
a = 14.3874945699
