Graph the points (3,3) and (2,1) on the coordinate plane.
Answer:
1. Over three, up three
2. Over two, up one
Step-by-step explanation:
Given the following question:
Point A = (3, 3)
Point B = (2, 1)
To find the answer, please understand where the x and y axis is located. Remember that the x is the line intersecting the y axis.
So, in order to plot point A and B, we have to remember that the first value represents x, and the second represents the y value.
(3, 3) = (x, y)
(2, 1) = (x, y)
For the first point we will move over three on the x axis, and then up three on the y axis.
For the second point we will move over two on the x axis, and then up 1 on the y axis.
Hope this helps.

Answer:
33
Step-by-step explanation:
Alright, so, let's break it down.
We know that d = negative 6 (-6)
Lets start with -5d.
Since d = -6, we have to do -5 × -6, which is 30.
So, now, we are using fractions. -6 plus 15.
(Which is, negative 6 plus 15)
That is 9. Since we are adding a negative number to a positive number, it will be the same way as 15 minus 6.
Now, we know that we are using division (due to the fraction line, we know that we are using division). Let's divide 9 into 3. That's 3, because 3 times 3 is also 9. Now, if we add 30 plus 3, we get 33, Therefore, the answer is 33.
Answer:
33
Step-by-step explanation:
-5(-6) + (-6) + 15/3
30 + -6 + 15/3
30 + 9/3

In rhombus ABCD, segments AC and BD are diagonals. If mZDAB = 160°, what is the measure of ZABE?
OA. 190°
ОВ.
170°
OC
10°
D.
100
Answer:
The correct option is OPTION C.
Step-by-step explanation:
Recall that for a rhombus, the diagonals bisect the interior angles.
This means that if we are given that:
m∠DAB=160°
Then:
m∠EAB=m∠DAB/2=160/2=80°
Also, recall that the diagonals of a rhombus are perpendicular. Therefore:
m∠AEB=90°
Hence, we can have a triangle that looks like the one shown below:
Recall that the sum of angles in a triangle is 180°. Therefore, we have that:
m∠AEB+m∠ABE+m∠EAB=180°
Hence, we can calculate m∠ABE to be:
m∠ABE =180-80-90
m∠ABE=10°
The correct option is OPTION C.

DON'T USE LINKS OR I WILL REPORT YOU!!!
Answer: Not reasonable
Step-by-step explanation:Answer:
No, it isn't a reasonable scale.
Step-by-step explanation:
if the scale is 1in=4in then 12 by 24 paper should equal a 48 by 96 painting. That is not the case since the painting is 48 by 120.
A more appropriate scale for a 1=4 ratio would be 12 by 30.

40/64 = 5/? what is the equivalent fraction
Answer:
40/64 = 5/8
Step-by-step explanation:
greatest commom dinaminator of 40 and 64 is 8 so,
divide each number by 8
40 divided by 8 =5
64 divided by 8 =8
Or you can do bc it gives you the 5 and the numerator you do 40 divided by 5 and get 8 so that means to get the second fraction you are divided the first one by 8 thats why 40 divided by 8 is 5 and youre going to do 64 divided by 8 which is 8. put the two numbers together and you get 5/8! :)

The Bridge Problem
A group of four people has to cross a bridge. It is dark, and they have to light the path with a flashlight. No more than two people can cross the bridge simultaneously, and the group has only one flashlight. It takes different time for the people in the group to cross the bridge:
Chris crosses the bridge in 1 minute,
Tracy crosses the bridge in 2 minutes,
Ashley crosses the bridge in 5 minutes,
Jalen crosses the bridge in 10 minutes.
How can the group cross the bridge in 17 minutes?
So, the first thing is that the group requires flashlight to cross the bridge. It also means that each time one person must return to bring back the flashlight.
Chris and Tracy cross the bridge in 2 minutes. ( The maximum time required by both of them would be 2 minutes)
Then Chris would return with flashlight in 1 minute.
Ashley and Jalen then cross the bridge in 10 minutes.
Now, Tracy will return with flash light in 2 minutes.
Then, Chris and Tracy will cross the bridge in 2 minutes.
Total time taken => 2+1+10+2+2 => 17 minutes.
Hope this helps :)
Answer:
Chris and Tracy cross the bridge together = 2 minutes
Chris goes back on his own (leaving Tracy across the bridge) = 1 minute
Chris gives the flashlight to Ashley
Ashley and Jalen cross the bridge together = 10 minutes
They give the flashlight to Tracy (who was waiting across the bridge)
Tracy goes back = 2 minutes
Chris and Tracy cross the bridge together = 2 minutes
Total 17 minutes

Please i need help, can someona explain how to solve the problems with the most easiest way to solve? Because this is so confusing
Answer:
Above your sheet, they give you formulas for the rectangular prism.
Method one;
V = L x W x H
Where "L" is length, "W" is width, and "H" is height.
Method 2;
V = B x H
Where "B" is the area of the base, and "H" is the height.
Now let's apply these formula to your questions:-
(Using method 2 for most of these problems)
1. If we look for the area of the base, we can see that 2 is the width and 4 is the length, so we would need to multiply those two to get the area of the base (2 x 4) = 8.
Now the height is 3.
So we plug this into our formula,
V = B x H
V = 8 x 3
V = 24 cubic feet
2. If we look at this question, we can see that this is a cube, meaning that all lengths are the same. To make this easier, we can use method 1 and just multiply the given lengths;
V = L x W x H
V = 4 x 4 x 4
V = 64 cubic inches
3. If we look for the area of the base, we can see that 5 is the width and the length is 20, so we would need to multiply those two to get the area of the base (5 x 20) = 100.
The height is 5.
So we plug this into our formula;
V = B x H
V = 100 x 5
V = 500 cubic yards
4) If we look for the area of the base, we can see that 3.2, if i'm correct, is the width and 5.4 is the length, so we would need to multiply those two to get the area of the base (3.2 x 5.4) = 17.28.
The height is 1.9.
So we plug this into our formula;
V = B x H
V = 17.28 x 1.9
V = 32.832, 32.83 cubic centimeters
Which function represents a reflection of f(x) = 5(0. 8)x across the x-axis? g(x) = 5(0. 8)–x g(x) = –5(0. 8)x g(x) = One-fifth(0. 8)x g(x) = 5(–0. 8)x.
The function which represents the reflection of provided function across the x-axis is,
[tex]g(x) = -5(0. 8)x[/tex]
What is reflection of function?The reflection of a function is flipping the original function with respect to a reference line.
The following steps used to for reflecting a the function-
Select the function which has to be reflected.Select a baseline or reference line over which the function has to be reflected.Mark the corners of the function at the equidistant from the reference line as the original function has, but in the opposite direction.The reflected function is now is facing the opposite direction.The function given in the problem is,
[tex]f(x) = 5(0. 8)x[/tex]
The function has the positive sign. Therefore, this function is located in the first quadrant.Now this function is reflected across the x-axis. This will lead this function in the fourth quadrant, with negative sign.
Therefore, the function become,
[tex]g(x) = -5(0. 8)x[/tex]
Hence, the function which represents the reflection of provided function across the x-axis is,
[tex]g(x) = -5(0. 8)x[/tex]

Miguel's irrigation tank for his large garden held 45. 5 gallons before he began to fill it at a rate of 17 gallons per minute.
Before he started watering the plants in his garden, Miguel's friend Alejandro checked his irrigation tank and found it contained 425 gallons.
If Alejandro is irrigating his plants at rate of 11. 5 gallons per minute, how much water will be in each tank when both tanks have the same amount of water?
Answer:
year, subtract that amount from the 230,000 gallons of seasonal water use. 230,000 gallons – 150,000 gallons = 80,000 gallons use for irrigation per year .

The figure will be a vertical reflection of itself about any horizontal line through two of the smaller 6-pointed stars.

__
Additional comment
A pattern will have horizontal reflection if there exists a vertical line about which the pattern can be reflected to itself. That is, there exists one (or more) vertical lines of symmetry.
Similarly, the pattern will have vertical reflection if there is a horizontal line about which the pattern can be reflected to itself. Such a line is a horizontal line of symmetry.
