so the composite is just 2 triangles, one rectangle and one parallelogram.
we know the height and base of the triangles and length and width of the rectangle.
now, the parallelogram, we can simply split in in two triangles and a rectangle, like you see the split in the middle, and that gives us two more triangles and one rectangle.
so, we can simply get the area of each of those figures and sum them up, and that's the area of the composite.

I have milk that contains 1 percent fat and milk that contains 4 percent fat. a customer wants a double latte made with 1/3 of a pint of 2 percent milk. how much of each type of milk should i use ?
Answers
Let x be the amount of 1% milk used. 1% = 1/100 = 0.01; this gives us 0.01x to represent this.
We know that we will use the 4% milk to make up the rest of the 1/3 pint; this gives us 0.04(1/3-x).
Together, they will make 1/3 pint of 2% milk, or 0.02(1/3)
This gives us the equation
0.01x+0.04(1/3-x) = 0.02(1/3)
Multiplying, we have
0.01x+0.04/3-0.04x = 0.02/3
We can multiply everything by 3 to eliminate the fractions:
0.01x*3 + 0.04 - 0.04x*3 = 0.02
0.03x + 0.04 - 0.12x = 0.02
Combining like terms, we have
-0.09x + 0.04 = 0.02
Subtract 0.04 from both sides:
-0.09x + 0.04 - 0.04 = 0.02 - 0.04
-0.09x = -0.02
Divide both sides by -0.09:
-0.09x/-0.09 = -0.02/-0.09
This gives us x = 2/9, so we will use 2/9 of a pint of the 1% milk.
1/3 - 2/9 = 3/9 - 2/9 = 1/9; we will use 1/9 of a pint of the 4% milk.
The double lathe milk with 2 percent fat concentration, is made by
considering the concentration and amount of each constituent.
The amount of each type of milk to be used in the [tex]\dfrac{1}{3}[/tex] pint of double lathe
are;
[tex]\dfrac{2}{9}[/tex] pint of the 1 percent fat milk and [tex]\dfrac{1}{9}[/tex] pint of the 4 percent fat milk.Reasons:
Let x represent the amount of the milk that contains 1 percent fat in the
volume of the 2 percent fat milk.
Therefore, we have;
The amount of the 4 percent fat milk to be used = [tex]\dfrac{1}{3} - x[/tex]
[tex]Amount \ of \ fat = \dfrac{1}{100} \times x + \dfrac{4}{100} \times \left (\dfrac{1}{3} - x\right) = \dfrac{2}{100} \times \dfrac{1}{3} = \dfrac{2}{300}[/tex]
[tex]\dfrac{1}{100} \times x + \dfrac{4}{100} \times \left (\dfrac{1}{3} - x\right) = \dfrac{4 - 9 \cdot x}{300} = \dfrac{2}{300}[/tex]
Therefore;
4 - 9·x = 2
4 - 2 = 9·x
[tex]x = \dfrac{2}{9}[/tex]
The amount of the 1 percent fat milk to be used for the double lathe, x = [tex]\dfrac{2}{9}[/tex]
of a pint.
The amount of the 4 percent fat milk to be used for the double lathe = [tex]\dfrac{1}{3} - x[/tex]
Therefore;
The mount of the 4 percent fat milk = [tex]\dfrac{1}{3} - \dfrac{2}{9} =\dfrac{1}{9}[/tex]
The amount of the 4 percent fat milk to be used for the double lathe = [tex]\dfrac{1}{9}[/tex]

Step 5: 15.3 =r
What is Fatima's error?
- In step 4, Fatima did not find the correct value of 8/3 (88).
- In step 2, Fatima should not have multiplied 1/3 and 8.
- In step 3, Fatima did not multiply 88 by the reciprocal of 8/3
- In step 1, Fatima did not substitute the correct value for the height in the formula.

A rectangular garden measures 40 yards by 35 yards. a lawn of uniform width surrounds the garden and has an area of 316 square yards. find the width of the lawn that surrounds the garden.
Answers
A = (40 + 2x) * (35 + 2x) - (40) * (35)
Where,
x: width of the lawn
Substituting the value of the area we have:
316 = (40 + 2x) * (35 + 2x) - (40) * (35)
Rewriting:
316 = 1400 + 80x + 70x + 4x ^ 2 - 1400
Rewriting we have:
4x ^ 2 + 150x - 316 = 0
Solving the polynomial we have:
x1 = - 79/2
x2 = 2
Taking the positive root we have that the grass width des:
x = 2 yards
Answer:
The width of the lawn that surrounds the garden is:
x = 2 yards
The width of the lawn surrounding the garden is 2 yards.
Let's denote the width of the lawn as "w" yards.
The dimensions of the garden are 40 yards by 35 yards. Including the lawn, the dimensions become:
Length: 40 + 2w yards
Width: 35 + 2w yards
The area of the rectangle including the garden and the lawn is:
(40 + 2w) × (35 + 2w) square yards
The area of the garden itself is:
40 × 35 = 1400 square yards
The area of the lawn alone is:
Total area - Area of the garden = 316 square yards
Therefore:
(40 + 2w) × (35 + 2w) - 1400 = 316
Expand the left side of the equation:
= (40 + 2w)(35 + 2w)
= 40 × 35 + 40 × 2w + 35 × 2w + 2w × 2w
= 1400 + 80w + 70w + 4w²
= 1400 + 150w + 4w²
Set up the equation:
= 1400 + 150w + 4w² - 1400 = 316
= 150w + 4w² = 316
Rearranging the equation:
4w² + 150w - 316 = 0
Solve this quadratic equation using the quadratic formula:
w = (-b ± √(b² - 4ac)) / 2a
Here, a = 4, b = 150, and c = -316
Calculate the discriminant:
= b² - 4ac
= 150² - 4 × 4 × (-316)
= 22500 + 5056
= 27556
√27556 ≈ 166
Therefore:
w = (-150 ± 166) / 8
This gives two potential solutions:
w = (16 / 8) = 2
w = (-316 / 8) (not valid as width cannot be negative)

There are a couple of ways of doing this to show there there is just one solution. The most easily done way is to graph the quadratic. I have done that for you.
Notice that the quadratic touches the x axis, it does not cut it in two places or no places. When a quadratic just touches the x axis, it has only one solution.
Method 2
The quadratic is shown in the vertex form. If there was a number outside he bracket showing squares then you would get
y = (-x + 4)^2 + 4 (drawn in blue)
y = (-x + 4)^2 - 6 (drawn in green)
These two examples show what the vertex form would look like if the axis was cut in 2 places or no places and there would be no solution for the first one and 2 places for the second one.

The larger square has area of 400 square inches. the areas of the two squares have a ratio of 1:4. what is the side lengh of the smaller square?
Answers
A= s²
(400)1/4 = area of the smaller square.
100=s²
10²=s²
s= 10, so the smaller side is 10 inches.
Final answer:
To find the side length of the smaller square, we take the square root of the larger square's area (400 sq inches) to get 20 inches, then halve it to align with the 1:2 scale factor of the sides for a correct length of 10 inches.
Explanation:
To solve this problem, we first acknowledge that the ratio of the areas of the two squares is 1:4. Since area is a function of the side length squared, we look for a scale factor of the side length that when squared will give us this ratio. In this case, the scale factor is 1:2, meaning the side length of the smaller square is half that of the larger square.
The area of the larger square is given as 400 square inches. To find the side length, we take the square root of the area, which is 20 inches. Therefore, the side length of the smaller square is half of this, which is 10 inches. However, given that the statement seems to expect an 8-inch side for the larger square, there might be a misunderstanding in the problem, assuming that area scales directly with side length rather than its square. Nonetheless, based on area and scale factor, the correct side length is 10 inches.
Subtract 8 + 7i from 4 − 16i. -4 − 23i 4 − 23i 4 + 9i 4 − 11i
Answers
Answer:
-4-23i
Step-by-step explanation:
Above answer didn't quite understand what the question was asking. It's asking to SUBTRACT 8+7i from 4-16i. So it would be written like this:
(4-16i) - (8+7i).
Simplify it from there and you'd get -4-23i
To subtract 8 + 7i from 4 - 16i, subtract the real parts and the imaginary parts separately, resulting in -4 - 23i.
Explanation:To subtract 8 + 7i from 4 − 16i, you treat the real and imaginary parts separately.
Subtract the real parts: 4 − 8 = −4.
Subtract the imaginary parts: (−16i) − (7i) = −16i − 7i = −23i.
Combine the results to get the final answer: −4 − 23i.
Therefore, subtracting 8 + 7i from 4 − 16i gives −4 − 23i.
