On a coordinate plane, which axis is the horizontal axis, and which is the vertical axis? Is there a way to graph points that are not whole numbers? How do you think you can do that? Describe some real-world situations that remind you of the coordinate plane.
Answer:
Horizontal axis is X
Vertical Axis is Y
You can graph points that are not whole numbers, you just have to add more lines or estimate where the point may be
Battleship maybe? Or like the longitude and latitude on a map?
A map is a real-world example of a coordinate plane.
What is a coordinate plane?A coordinate plane is a rectangular plane consisting of a horizontal and a vertical axis.
On a coordinate plane, the x-axis is the horizontal axis, and the y-axis is the vertical axis.
To graph the points that are not whole numbers, use the grid lines on the graph to estimate the position of the point.

How do I solve this radical and then check all the solutions?
Answer:
This problem of equations involving surds can be solved by :
Firstly,square both sides of the equation to do away with the surd
(√x+3)²=(x-3)²
Next,we do away with the surd or let me put it as sign of square root and FOIL out the RHS
x+3=x²-6x+9
Rearranging leads to:
x²-6x-x+9-3=0
x²-7x+6=0 which factorises to:
(x-6)(x-1)=0
Finding the zeros leads to
x=6 or 1
We now conduct a test to see which value(s) of x satisfy the equation
√6+3=6-3
√9=3
3=3, so x=6 is true
Now for 1,
√1+3=1-3
√4 is not equal to -2
Therefore we conclude that x=6

what must be added to -3/8 to get 5/16 ?
Answer:
[tex]\frac{11}{16}[/tex]
Step-by-step explanation:
[tex]-\frac{3}{8}[/tex] + x = [tex]\frac{5}{16}[/tex]
x = [tex]\frac{5}{16}[/tex] - ( [tex]-\frac{3}{8}[/tex] ) = [tex]\frac{5}{16}[/tex] + [tex]\frac{3}{8}[/tex] = [tex]\frac{5 + 6}{16}[/tex] = [tex]\frac{11}{16}[/tex]
x = [tex]\frac{11}{16}[/tex]
-3/8=5/16
put x after -3/8 to find 5/16
-3/8+x=5/16
find x
move -3/8 to the other side
sign changes from -3/8 to 3/8
-3/8+3/8+x=5/16-3/8
x=5/16-3/8
find the common denominator which is 16
multiply by 2 for -3/8
(-3)(2)=-6
(8)(2)=16
x= 5/16--6/16
negative sign and negative sign= +positive sign
x= 5/16+6/16=11/16
answer: x=11/16

Answer:

Step-by-step explanation:
when you divide a fraction, you actually multiply by the reciprocal
Answer:
The correct answer is A, 4/5 x 5/4.
Step-by-step explanation:
I just remember to Keep Change Flip which means keep the first fraction exactly how it is, change the sign to a division sign, and flip the last fraction. So, go from 4/5 ÷ 4/5 = 4/5 x 5/4.

Let's ignore the four corners for now.
Along the top, the length is 145 cm. Each tile is 25 mm, which is equivalent to 2.5 cm. So she'll need 145/2.5 = 58 tiles across the top
Similarly, she'll also need 58 tiles across the bottom as well because that length is also 145 cm.
Along the left side, she'll need 75/2.5 = 30 tiles and the right side is the same story.
So far we calculate 58+58+30+30 = 176 tiles
Add in the four corners to get 176+4 = 180 tiles total
-------------------------
A quicker method is to divide the perimeter (440 cm) over the side length of each tile (2.5 cm) and we get 440/2.5 = 176, which represents the number of tiles along the top, bottom, left and right sides. Again we're ignoring the corners. So we'll have to add them back in to get 176+4 = 180.

An open rectangular cistern when measured from outside is 1.35 metre long 1.08 metre board and 90 cm It is made up of iron which is 2.5 cm find the capacity of the question and the volume of the iron used.
Answer:
The capacity of the cistern is [tex]1.2231~m^3[/tex]
The volume of iron used is [tex]0.0891~m^3[/tex]
Step-by-step explanation:
Volume
The volume of a rectangular box of dimensions x,y,z is given by:
V = x.y.z
The external dimensions of the rectangular cistern are 1.35 m, 1.08 m, and 0.90 m, thus the external volume is:
[tex]V_e=1.35*1.08*0.90=1.3122~m^3[/tex]
The cistern is made of iron 2.5 cm= 0.025 thick, thus the internal dimensions are:
1.35 - 0.025 = 1.325 m
1.08 - 0.025 = 1.055 m
0.90 - 0.025 = 0.875 m
The internal volume is:
[tex]V_i=1.325*1.055*0.875[/tex]
[tex]V_i=1.2231~m^3[/tex]
The capacity of the cistern is 1.2231~m^3
The volume of iron used is the difference between the external and the internal volumes:
[tex]V_{iron}=1.3122~m^3-1.2231~m^3[/tex]
[tex]V_{iron}=0.0891~m^3=89.1~lt[/tex]
The volume of iron used is [tex]0.0891~m^3[/tex]
Molly is making bags of trail mix for the hiking club. She will use 20 ounces of walnuts. 11.1 ounces of almonds, and 24.8 ounces of cashews. This amount makes 26 bags of trail mix. How many ounces are in each bag?
Answer:
2.15 ounces
Step-by-step explanation:
The total ounces of nuts in the bag is calculated as:
20 ounces of walnuts + 11.1 ounces of almonds + 24.8 ounces of cashews = 55.9 ounces.
From the question we are told that these amounts make 26 bags.
The number of ounces that are in each bag is calculated as:
26 bags = 55.9 ounces
1 bag = x ounces
Cross Multiply
26 bags × x ounces = 1 bag × 55.9 ounces
x ounces = 1 bag × 55.9 ounces/26 bags
x ounces = 2.15 ounces
Therefore, there are 1.94 ounces in each bag

Students need at least 75 hours of volunteer service to meet their graduation requirements. Sally has already completed 48 hours. Write and solve an inequality to determine how many more hours Sally needs to complete.
Answer:
48+x=75
Step-by-step explanation:
Subtract 48 from both sides. 75-48 is equal to 27. x=27
Answer:
x [tex]\geq[/tex] 27
Sally has to complete at least 27 more hours
Step-by-step explanation:
Let x represent the number of hours she will complete next
Since students need at least 75 hours, use a greater than or equal to sign.
The total number of hours that Sally will complete can be represented by
x + 48, since she has already done 48 hours.
Use the greater than or equal to sign, and put 75 on the other side:
x + 48 [tex]\geq[/tex] 75
Next, solve the inequality:
x + 48 [tex]\geq[/tex] 75
x [tex]\geq[/tex] 27
So, Sally has to complete at least 27 more hours.

If z is inversely proportional to r, and z=32 when r=1.5, find r when z=8.
Answer:
votes
z is inversly proportional to r then z = k/r
zr = k
If z = 32 when r = 1.5
32(1.5) = k
48 = k
k = 48
If z = 8 then r = ?
8r = k
8r = 48
Divide to each side by 8.
r = 48/8
r = 6

At the end of a snow storm, Emily saw there was a lot of snow on her front lawn. The
temperature increased and the snow began to melt at a steady rate. There was a depth
of 15 inches of snow on the lawn when the storm ended and after 4 hours, the depth
of snow was down to 12 inches. Write an equation for S, in terms of t, representing
the depth of snow on Emily's lawn, in inches, t hours after the snow stopped falling.
Answer: S
Submit Answer
Oh
Answer:
[tex]y = \frac{4}{3}x + 15[/tex]
Step-by-step explanation:
•First we must find out how many inches of snow melted so we can find the slope.
15 inches - 12 inches = 3 inches
•The snow melts 3 inches every 4 hours. This statement can be rewritten as:
[tex]\frac{4}{3}[/tex]
•We know that the snow started at 15 inches so that will be our y-int.
•Now we can start combining these terms to create an equation.
[tex]m = \frac{4}{3}[/tex]
[tex]b = 15[/tex]
•All we have to do is substitute these terms for the corresponding variables.
[tex]y = mx +b[/tex] → [tex]y = \frac{4}{3}x + 15[/tex]
[tex]y = \frac{4}{3}x + 15[/tex]
