Given:
The figure of a triangle DEF.
To find:
The coordinate of image of given triangle after reflection over y-axis.
Solution:
The vertices of given triangle are D(1,4), E(4,3), F(2,0).
If a figure is reflected over the y-axis, then the rule of reflection is
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]D(1,4)\to D'(-1,4)[/tex]
[tex]E(4,3)\to E'(-4,3)[/tex]
[tex]F(2,0)\to F'(-2,0)[/tex]
Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).
Is the equation y=4x proportional
the sum of two rational numbers is -8 1/4. if one of the numbers is -5 2/3, find the other number.
Answer:
-2 7/12
Step-by-step explanation:
Let x represent the unknown number.
x + (-5 2/3) = -8 1/4
Adding 5 2/3 to both sides of the equation tells us ...
x = 5 2/3 -8 1/4 = -2 7/12
The other number is -2 7/12.
_____
The difference can be found as ...
-(8 1/4 -5 2/3) = -(8 3/12 -5 8/12) = -((8 -5) +(3/12 -8/12)) = -(3 -5/12)
= -(2 7/12)

What fraction of 250 gallons is 144 L? Give your answer in simplest form. 1 gallon = 45L.
HELP URGENT FUE IN 10 mins
Answer:
0.0128
Step-by-step explanation:
Given that: 1 gallon = 45 L
Then,
x gallons = 144 L
So that,
x gallons = [tex]\frac{144}{45}[/tex]
= 3.2
i.e 3.2 gallons = 144 L.
The fraction of 250 gallons that is 144 L can be determined as;
The fraction = [tex]\frac{3.2}{250}[/tex]
= [tex]\frac{8}{625}[/tex]
= 0.0128
The fraction of 250 gallons that is 144 L is 0.0128.
Check: 250 gallons = 250 x 45
= 11250 L
Fraction required = [tex]\frac{144}{11250}[/tex]
= 0.0128

On a certain hot summer day, 431 people used the public swimming pool. The daily prices are 1.50 for children and 2.00 for adults.The receipts for admission totaled to $825.50. How many children and how many adults swam at the public pool that day?
Answer:
the no of children and no of adults swam that day is 73 and 358 respectively
Step-by-step explanation:
Let us assume the no of children and no of adults swam that day be x and y
Now as per the question
The following equations are
x + y = 431
we can write as
x = 431 - y
1.50x + 2y = $825.50
1.50(431 - y) + 2y = $825.50
646.50 - 1.50y + 2y = 825.50
0.5y = 179
y = 358
And x = 431 - 358
= 73
Hence, the no of children and no of adults swam that day is 73 and 358 respectively

i have 8 boxes of chocolate i eat 3 chocolates from each box i now have 72 chocolates in total
Answer: there were 12 chocolates in each box. (Originally, before any got eaten)
Step-by-step explanation: let x represent the total amount of chocolates in each box.
8x - 3(8) = 72
8x - 24 = 72 add 24 to both sides
8x = 96 divide both sides by 8
X = 12
Answer:
That means you had 48 chocolates in each box
Step-by-step explanation:
Since you eat 3 chocolates from all 8 boxes, you do this:
8 x 3 which = 24
Now since you have 72 chocolates left you do this:
72 - 24 which = 48
So, therefore, there were originally 48 chocolates in each box
(Don't eat so much chocolate lol you could get sick)

What is the area of this shape? ANSWER AS FAST AS YOU CAN!!!!
Answer: 5x4x8x4x5x2x6x8x1
Step-by-step explanation:
Answer:
32 Square centimeters
Step-by-step explanation:
You have to seperate the shape into triangles and rectangles. if you do this, you get 2 identical triangles and 2 different rectangles. one of the rectangles is 8 square cm, the other is 12. you can see that the base of each of the 2 triangles is 3 cm long. 2 halves=1 whole, so the 2 triangles turn into 1 rectangle. therefore, you have to add 12+12+8. That is 32 square centimeters.

A tree's shadow is 4.8 meters long on level ground, as shown. The angle of elevation from the tip of the shadow to the sun is 50°. Based on this information, what is the approximate height of the tree? Write a trig equation, show your work and pick your answer. A. 3.1 m B. 3.6 m C. 5.7 m D. 7.5 m
The height of the tree is 5.7m
What is angled of elevation?Angle of elevation is the angle between the horizontal line and the line of sight.
Analysis:
The height of the tree and the tree's shadow form a right angle triangle with the line of sight.
let the height of tree be h
tan 50 = h/4.8
h = 4.8 x tan 50
h = 4.8 x 1.191 = 5.7m
In conclusion, the height of the tree is 5.7m
