Answer:
434
Step-by-step explanation:
310 * 1.4 = 434
or if you want to break it up more:
10% of 310 = 31 (to get 10% divide by 10)
to get from 10% to 40% multiply your answer by 4
31 * 4 = 124
so 40% = 124
this means over the three months Allison's rock collection increased by 124.
to get the total amount of rocks Allison has now add the increase to the original value
310 + 124 = 434
find the value of the expression |x|/x id x=-8,-5,1,7,128 write the expression without the absolute value symbol for these values of x x>0
Using the definition of the absolute value function, it is found that:
The result of the expression is of -1 for x = -8 and x = -5.The result of the expression is of 1 for x = 1, x = 7 and x = 128.What is the absolute value function?It measures the distance of a point x to the origin, and is defined by:
[tex]|x| = -x, x < 0[/tex]
[tex]|x| = x, x \geq 0[/tex]
As for the expression used in this problem:
[tex]\frac{|x|}{x} = -\frac{x}{x} = -1, x < 0[/tex]
[tex]\frac{|x|}{x} = \frac{x}{x} = 1, x > 0[/tex]
Hence:

Answer:
just to be clear the answers are here:
Step-by-step explanation:
If x=1, then |x|/x= 1
If x=7, then |x|/x=1
If x=128, then |x|/x=1
If x>0, then |x|/x=1
If x=-8, then |x|/x=-1

9.8x+17=7.6x-16
??????
Q: What is 9.8x+17=7.6x-16?
A: Your answer should be 2.8867, I tried the best I could.
Answer:
x= -15
Step-by-step explanation:
You subtract 7.6 from 9.8
then you left with 2.2x+17=-16
Subtract 17 from -16 ( -33 )
Then you'll divide 2.2 and -33
x= -15
Find the equation of the line below?
Answer:
y = 1/2x + 1/2
Step-by-step explanation:
first list a few points to find the slope
(1,1) (3, 2)
y2 - y1/x2 - x1
2 - 1/3 - 1
1/2
y = 1/2x + b
to find the slope use a point you didnt use yet (since its tricky to find the intercept looking at the graph)
(-1, 0)
0 = 1/2(-1) + b
0 = -1/2 + b
b = 1/ 2
lets check:
point: (-3, -1)
y = 1/2x + 1/2
-1 = 1/2(-3) + 1/2 ?
-1 = -3/2 + 1/2 ?
-1 = -1
Answer:
Slope intercept form;
y = mx + b
If we look at the graph, we can see the line intercepts with y axis at around 0.5, so 0.5 is our y - intercept.
If we look at the slope it rises 1/2
Though we can double check by using two points of the line:-
Δy y2 - y1
___= ______
Δx x2 - x1
One point of the line, (1,1)
Second point of the line, (3,2)
Plug it into the formula:
2 - 1 1
____ = ____, 1/2 is the slope
3 - 1 2
Now we use it in our equation;
y = 1/2x + 0.5

Find the value of angle marked x
Based on the given diagram we see that all the exterior angle is in a straight line with the interior angle.
Using the known angle measure, we know that the shape has angles of measure, 123 degrees, 94 degrees, 79 degrees, and '180 - x' degrees
Also, the sum of all the angles in a quadrilateral, any four-sided shape, is 360 degrees.
Now using the knowledge gained lets set up the equation
[tex]123 + 94 + 79 + 180 - x = 360\\476 - x = 360\\-x = -116\\x = 116[/tex]
Therefore x is 116 degrees.
Hope that helps!

nice green square lol
90° is the measure of angle x°.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
Here, given that,
the figure is a square,
so, all its angle = 90 degrees
Now, the x = (180-90)=90
Hence, 90° is the measure of angle x°.

Solve the equation
3/2 - 6x) + 1 = 3 – 5x.
Answer:
x = - 1/2
Step-by-step explanation:
(3/2 - 6x) + 1 = 3 - 5x
-6x + 5/2 = 3 - 5x
5/2 = 3 - 5x + 6x
5/2 = 3 + x
5/2 - 3 = x
-1/2 = x
x = -1/2
Please mark me the brainliest!?!
[tex] \frac{3}{2} - 6x +1 = 3 - 5x \\ [/tex]
Plus sides 6x
[tex] \frac{3}{2} - 6x + 6x + 1 = 3 - 5x + 6x \\ [/tex]
[tex] \frac{3}{2} + 1 = 3 + x \\ [/tex]
Subtract sides -3
[tex] \frac{3}{2} + 1 - 3 = 3 - 3 + x \\ [/tex]
[tex] \frac{3}{2} - 2 = x \\ [/tex]
[tex] \frac{3}{2} - \frac{4}{2} = x \\ [/tex]
[tex]x = - \frac{1}{2} \\ [/tex]

675 x 78 : 567 =
can you stop deleting my question.
Answer:
675 x 78/567
First let's find the product of the numerator;
(675 x 78) = 52,650
Now we divide by 567:
52,650/567 = 92.85, which is around 92.90

Please rate and mark me the brainiest!!
Hey there!
Let's solve your equation step-by-step.
[tex]\fbox{5y−6=2y(9)−32}[/tex]
Step 1: Simplify both sides of the equation.
[tex]\fbox{5y−6=2y(9)−32}[/tex]
[tex]\fbox{5y+−6=18y+−32}[/tex]
[tex]\fbox{5y−6=18y−32}[/tex]
Step 2: Subtract 18y from both sides.
[tex]\fbox{5y−6−18y=18y−32−18y}[/tex]
[tex]\fbox{−13y−6=−32}[/tex]
Step 3: Add 6 to both sides.
[tex]\fbox{−13y−6+6=−32+6}[/tex]
[tex]\fbox{−13y=−26}[/tex]
Step 4: Divide both sides by -13.
[tex]\fbox{−13y/−13 = −26/−13}[/tex]
[tex]\fbox{y=2}[/tex]

Answer:
{x | x = –5, –3, 1, 2, 6}
Step-by-step explanation:
The domain of a function includes all input values entered in the oval for input, while the range includes all the values in the output oval.
From the mapping given in the attachment, we have the following possible values of the function in the input oval as: -5, -3, 1, 2, 6.
These x-values make up the domain of the function, and represented as: {x | x = –5, –3, 1, 2, 6}
A rectangular prism has a length of 10 in., a width of 2 in., and a height of 312 in. the prism is filled with cubes that have edge lengths of 12 in. how many cubes are needed to fill the rectangular prism? enter your answer in the box. to fill the rectangular prism, cubes are needed.
Step-by-step explanation:
that is a strange question. you will see in a moment why.
I suspect your teacher just wants to do the exercise to have a large volume and then see how often a small volume fits into that large volume.
we can do that quickly:
large volume = 10×2×312 = 6240 in³
small (cube) volume = 12×12×12 = 1728 in³
so, we could put 6240/1728 = 3.611111111... cubes into a volume as the prism has.
now why did I phrase this so strangely ?
because the prism not only has volume but also a shape.
it is a narrow but high container with the small dimensions being 10 in and 2 in.
the cubes have a side (or edge) length of 12 in. that is not compatible with the 10 in and 2 in cubes of the prism.
not a single one cube would fit into the prism.
so, the realistic answer is : 0 cubes.
if it does not matter that the cubes would stand out of the prism, we could simply stack a single file of cubes along the height of the prism :
312/12 = 26 cubes.
so, we could stack 26 cubes inside the height of the prism.
so, I conclude, this is either a trick question (and 0 is the true answer), or there is a mistake in the question.
possibly in the dimensions of either the prism or the cubes.
for example, let's assume the cubes have an actual side length of 2 in (and not 12 in).
then the small (cube) volume is : 2×2×2 = 8 in³
and they will fit into the prism also shape wise.
6240/8 = 780 cubes
so, we would need 780 cubes of that size to fill the prism.
or, as another example, the cubes have a side length of 1/2 in.
then the small (cube) volume = 1/2³ = 1/8 in³
6240/(1/8) = 6240 × 8 = 49,920 cubes
in that case we would need 49,920 cubes to fill the prism.

A taxicab service charges customers by the mile. The graph
shows the number of miles a taxicab drives and the amount of
money the customer pays.
Which statement best describes the rate of change for the
situation?
The amount a customer pays increases $0.50 per
mile driven
The amount a customer pays increases $0.60 per
mile driven
The amount a customer pays increases $12 per mile
driven.
The amount a customer pays increases $21 per mile
driven
Answer:
The second option: The amount a customer pays increases $0.60 per mile driven.
Step-by-step explanation:
As seen on the graph, we are given the points (20,12) and (35,21).
This means that at 20mi driven, the amount paid is $12, and at 35mi driven, the amount is $21.
To find the rate of change we divide the distance driven by the cost to find the cost per mile:
20/12 = 0.6
35/21 = 0.6
The slope is 0.6, so it costs an extra $0.6 for every mi driven. Therefore it is the second option: The amount a customer pays increases $0.60 per mile driven.
Hope this helped!
Answer:
The amount a customer pays increases $0.60 per mile driven.
Step-by-step explanation:
$0.6/mi is the rate of change, y = mx + b, so m.is also called rate of change & b is the initial value of x, in the graph b = 0. making m the subject of the equation, then m(roc) = 0.6.
