The volume of a box is 9cm³ and its base area is 20cm². What is the height of the whole box
Answer:
0.45 cm
Explanation:
In order to find the height of any shape given the volume and base area.
Simply divide the volume by the base area.
Here given:
Volume: 9 cm³Base area: 20 cm²Height:
volume ÷ base area = 9 ÷ 20 = 0.45 cmCarmen has 4 baby bunnies. Each bunny weighs 1/5 of a pound. How much do the bunnies weigh all together?

what expression is equivelent to 4x-10/2
Answer:
4x-5
Step-by-step explanation:
In two or more complete sentences, describe the transformation(s) that take place on the parent function, f(x) = log(x), to achieve the graph of g(x) = log(-2x-4) + 5
Please solve this for me!!!!
Step-by-step explanation:
Howdy there :)
To describe the transformation of the parent logarithmic function, you just need to follow these rules
1. A + on the outside of the parentheses will mean a vertical shift upwards. As such, the transformation is moved 5 units up. If it was -, it would move 5 units down.
2. The inside of the parentheses will result in a horizontal shift right 4 units. The rule to remember is that these kinds of functions follow x(a - b) rules, meaning that when the 4 is subtracted, we are really talking about a positive four, unlike in standard arithmetic. Vice versa, a + 4 will mean a -4 four, since a - -4 is the same as a + 4. As such, we will move in the positive direction (right) on the y axis.
3. Since x is now -2x, we are reflecting about the y axis, meaning the function will switch from left to right or right to left.
4. The 2 in front of it represents a vertical dilation by a factor of 2. This is because our constant, 2, is greater than 1. If the number were in between 0 and 1, it would represent a vertical compression by the constant number.
find the equaton of the line passing through the points (2,11) and (-8, -19) y= ?x ?
Find the slope:
(-19 - 11) / (-8 - 2) = (-30/-10) = 3
Find the y intercept:
y = mx + b
11 = 3(2) + b
b= 5
So equation is:
y = 3x + 5

Positive numbers are always greater than negative numbers, so the statement would be true
Identify the range of the exponential function?
Answer:
The range of an exponential function, or any function is all the possible y values the function can spit out.
In MOST exponential functions they will be x>0
I am talking about the standard form: y = a * b^x
I cannot tell you the range for YOUR exponential function without seeing it first.
slope for y=2x+3 and y intercept
Answer:
slope = 2, y-intercept = 3
Step-by-step explanation:
» Concepts
All straight lines can follow the slope-intercept form, y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. The slope is the constant rate of change, and the y-intercept is where the line intersects at the y-axis.
» Application
We are asked to find the slope and y-intercept of the equation, y = 2x +3, given the form y = mx + b. As you can see, in the place of m (the slope), there is the number 2, making the slope 2. Then, in the place of b (the y-intercept), there is the number 3, making the y-intercept 3.

Answer:
y = 2x
Step-by-step explanation:
Parallel line share the same slope, therefore we can put any parallel line of y = 2 (x + 1) in equation as: y = 2x + k
As the parallel has to intercept with point (2/3, 1/3), simply put the coordinate into the equation to get value of k
2/3 = 2(1/3) + k
k = 0
Therefore the equation of this parallel line is y = 2x
5. A square on the coordinate plane has vertices
at A(-3,0), B(1, 2), C(2,-1), and D(-2,-4). After a
dilation using a scale factor of 3, what are the
new coordinates of D'?
Reason:
Multiply each coordinate of D(-2,-4) by the scale factor 3 to get (-6, -12)
In other words, triple each coordinate of point D.
This trick only works if the center of dilatioin is the origin.
Johnson can tile a 100 square foot floor in 7 hours. Nathan can tile the same area in 9 hours. Enter an equation that can be used to find the time in hours,t it would take Johnson and Nathan to tile a 100 square foot area together.
The equation that can be used to find the time t, in hours, it would take Johnson and Nathan to tile a 100 square foot area together is 3.9375 hours, which approximates to 4 hours.
How are number of people to time needed to complete a task related?More people to do a task means less time it will take.
Less people to do a task means more time it will take.
Thus, they are inversely related.
If x men take y time for a work,(assume all men have same strength)
We can define a constant as "Manpower" needed for doing that specific work.
Let we define:
Manpower needed for a work = y + y + y + .. + y = Time per man × count of men
Manpower needed for a work = xy
For this case, we're specified that:
Work in consideration = Tiling 100 sq. foot floorTime it takes by Johnson to do this work = 7 hoursTime it takes by Nathan to do this work = 9 hoursSo, we see that strength of Johnson and Nathan are different.
Let the general manpower (from some frame of a general public or any third frame) needed by this work be M.
Then, Johnson delivers M manpower in 7 hours or M/7 manpower in one hour.
In the similar way, Nathan delivers M/9 manpower per hour.
Thus, if Nathan and Johnson work together, they can deliver: [tex]\dfrac{M}{9} + \dfrac{M}{7} = M\dfrac{9+7}{63} = \dfrac{16M}{63}[/tex] manpower per hour.
Let it takes them together h hours to complete the work.
That means, in 'h' hours, their together work power will accumulate to M manpower.
Or, we can say:
[tex]h \times \dfrac{16M}{63} = M\\\\h = \dfrac{63M}{16M} = \dfrac{63}{16} = 3.9375[/tex]
Thus, the equation that can be used to find the time t, in hours, it would take Johnson and Nathan to tile a 100 square foot area together is 3.9375 hours, which approximates to 4 hours.

calculate the number of subsets and the number of proper subsets for the set.
{1/6, 1/7,1/8,1/9 }
A. 16;15
B.15;16
c.14;15
D.15;14
A set of n elements has 2ⁿ subsets. One of these subsets is the set itself, so this set would have 2ⁿ - 1 proper subsets.
The given set has 4 elements, so it has 2⁴ = 16 subsets and 2⁴ - 1 = 15 proper subsets.
Just to illustrate the claim, we have
• subsets of size 0 (1 of these):
{ } (empty set)
• subsets of size 1 (4 of these):
{1/6}, {1/7}, {1/8}, {1/9}
• subsets of size 2 (6 of these):
{1/6, 1/7}, {1/6, 1/8}, {1/6, 1/9}, {1/7, 1/8}, {1/7, 1/9}, {1/8, 1/9}
• subsets of size 3 (4 of these):
{1/6, 1/7, 1/8}, {1/6, 1/7, 1/9}, {1/6, 1/8, 1/9}, {1/7, 1/8, 1/9}
• subsets of size 4 (1 of these):
{1/6, 1/7, 1/8, 1/9}
and the last one is the only subset that is not a proper subset, because that subset = the set.
The number of subsets are 16 and number of proper subsets for the set are 15. So, correct option is A.
The set {1/6, 1/7, 1/8, 1/9} has 4 elements.
To calculate the number of subsets, including both the proper and improper subsets, you can use the formula 2ⁿ, where n is the number of elements in the set.
So, for this set, there are 2⁴ = 16 subsets.
To calculate the number of proper subsets, you subtract 1 from the total number of subsets (to exclude the empty set).
So, the number of proper subsets is 16 - 1 = 15.
Hence, option A is correct, the number of subsets are 16 and number of proper subsets for the set are 15.
