Answer:
15cm and 12cm
Step-by-step explanation:
From the question,The ratio of the length and breadth of a rectangle is 5 to 4
We assume The Lenght of the field= 5x
The breadth = 4x
Area= (5x × 4x)= 180
20x^2= 180
X^2=
X= √9
X=3cm
The Lenght of the field= 5×3= 15cm
The breadth = 4×3=12cm

describe the transformation g(x) = 2(х-4)^2 +2
Answer:
Step-by-step explanation:
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
horizontal shift- right four units
vertical shift- up 2 units
Reflection about the x-axis: None
Reflection about the y-axis: None
Vertical Compression or Stretch: Stretched

Triangle QRS is reflected over y = 2. What are the coordinates of Q'?
Answer:
(1,6)
Step-by-step explanation:
In order to reflect a point over a horizontal line, you need to count how many units it takes to reach that line (going vertically). Once you have that number, count that many units starting from that point on the line (again, going vertically), then that is your reflected point.
Counting from point Q to the line y = 2, it takes 4 units. So starting from that point on the line where I left off, I would count another 4 units, taking me to (1,6). The picture below explains it better visually.
20-4x-15-4x=-6x-45+8x
Answer: x = 5
Step-by-step explanation:
Hey there! If you have any questions, feel free to let me know in the comments.
Step 1: Simplify 20 - 4x - 15 - 4x to 5 - 8x.
5 - 8x = -6x - 45 + 8x
Step 2: Simplify -6x - 45 + 8x to 2x - 45.
5 - 8x = 2x-44
Step 3: Add 8x to both sides.
5 = 2x - 45 + 8x
Step 4: Simplify 2x - 45 + 8x to 10x - 45.
5 = 10x - 45
Step 5: Add 45 to both sides.
5 + 45 = 10x
Step 6: Simplify 5 + 45 to 50.
50 = 10x
Step 7: Divide both sides by 10.
50/10 = 10x/10
Step 8: Simplify 50/10 to 5.
x = 5
Answer:
Step-by-step explanation:
Here you go mate
step 1
20-4x-15-4x=-6x-45+8x equation
step 2
20-4x-15-4x=-6x-45+8x simplify for x
20+(-4x)+(-15)+(-4x)=(-6x)+(-45)+8x
step 3
(-4x+-4x)+(20+(-15)=(-6x+8x)+(-45) add brackets to seperate the equations
step 4
-8x+5=2x+-45 combine the terms that are alike
step 5
-8x+5(-2x)=2x-45(-2x) subtract -2x(the ones in the brackets)
-10x+5=-45
step 6
−10x+5(-5)=−45(-5) subtract -5
-10x=-50
step 7
-10x/-10=-50/-10 divide by -10
step 8

Stefan is making meringue with egg whites and sugar. He uses 505050 grams of sugar for every egg white.
If Stefan uses 101010 egg whites, how many grams of sugar does he use?
grams
Answer:
Stefan uses 500 grams of sugar with 10 egg whites.
Step-by-step explanation:
Given that Stefan is using 50 grams of sugar with one egg white.
In order to find the quantity of sugar for more eggs, we have to multiply the amount of sugar for one egg with number of eggs.
Now,
We have to find the quantity of sugar for 10 eggs.
[tex]Sugar\ for\ 10\ eggs = 10*50 = 500[/tex]
Hence,
Stefan uses 500 grams of sugar with 10 egg whites.
Answer:
500 grams

Each vertical cross-section of the triangular prism shown below is an isosceles triangle.
What is the height, h, of the triangular prism?
Round your answer to the nearest tenth.
The height is
units.
Answer: The height is 3 units.
Step-by-step explanation:
By using the give figure we can form right angle out of the whole figure with a base of 4 and an hypotenuse of 5.
By using this information we can use the Pythagorean Formula to find the height
a^2 + b^2 =c^2 a= base, b = height and c will be the hypotenuse.
4^2 + b^2 = 5^2 Solve for B
16 + B^2 = 25
-16 -16
b^2 = 9
b = [tex]\sqrt{9}[/tex]
b = 3
The height, h, of the triangular prism is 3 units.
What is an isosceles triangle?Isosceles triangles are those triangles that have at least two sides of equal measure and two base angles are equal.
Given that, vertical cross-section of the triangular prism shown in the given figure is an isosceles triangle.
Here, equal sides of an isosceles triangle is 5 units and base of the isosceles triangle is 8 units.
By using Pythagoras theorem,
5²=h²+4²
25=h²+16
h²=9
h=3
Therefore, the height, h, of the triangular prism is 3 units.

Which graph represents the solution to the system of inequalities below?
5x - 4y > 4
x + y < 2
Answer:
The correct option is;
B
Step-by-step explanation:
The given system of inequalities are;
5·x - 4·y > 4...(1)
x + y < 2...(2)
Representing both inequalities as a function of "y", gives;
For, 5·x - 4·y > 4...(1), we have;
-4·y > 4 - 5·x
y < 4/(-4) - 5·x/(-4)
∴ y < 5·x/4 - 1
For x + y < 2...(2), we have;
y < 2 - x
Therefore, y is less than the values given by the equation of the straight line equalities, and the feasible region is given by the common region under both dashed lines representing both inequalities as shown in the attached diagram created using Microsoft Excel
The correct option is therefore, B.

Write an equation of the line in slope-intercept form given the graph below.
(2.1)
(0, 2)
Answer:
y = -0.5x + 2
Step-by-step explanation:
m=(y2−y1)/(x2−x1)
m=(1-2)/(2-0)
m (slope) = -1/2 or -0.5
y = mx + b (we need b now, y-int)
1 = -0.5(2) + b
b - 1 = 1
b = 2
Now we have the slope (m) and the y-intercept (b), we can rewrite it as such:
y = -0.5x + 2
Hope this helped!
*Remember the equation of a line in slope-intercept form is y=mx+b. In this problem, we found the slope and y-intercept.

Answer:
lemon cookies = 70 calories
fudge cookies = 95 calories
Step-by-step explanation:
Lemon cookies = "x"
Fudge cookies = "y"
As per what is given;
3x + 2y = 400
2x + 3y = 425
Multiply the first equation by (-3), and the second by (2)
-9x - 6y = -1200
4x + 6y = 850
________________
-5x = - 350
Inverse operations;
-5x = -350
/-5 /-5
x = 70
Subsitute back in;
3x + 2y = 400
3(70) + 2y = 400
Simplify, inverse operations;
210 + 2y = 400
-210 -210
2y = 190
y = 95

On Monday, Sean bought 3 cookies and 5 cakes and spent $78.75. On Tuesday, Sean bought 8 cookies and 2 cakes and spent $40.
Find the price for one cookie and one cake.
Answer:
1 cookie = $1.25 1 cake = $15
Step-by-step explanation:
set up a system of equations:
let x = 1 cookie
let y = 1 cake
3x + 5y = 78.75
8x + 2y = 40
I multiplied the first equation by 2 to get: 6x + 10y = 157.50
I multiplied the second equation by -5 to get: -40x - 10y = -200.00
If you add both equations, the y-terms will be eliminated
-34x = -42.50
x = 1.25
Plug in 1.25 into equation to find value of y: 8(1.25) + 2y = 40
10 + 2y = 40
2y = 30
y = 15
