Ashley would use [tex]\(\frac{2}{15}\)[/tex] cup of vinegar to make [tex]\(2/3\)[/tex] of her salad dressing recipe.
To find out how much vinegar Ashley would use to make 2/3 of her salad dressing recipe, we need to calculate the amount of vinegar used in the full recipe and then scale it down to 2/3 of that amount.
In the full recipe, Ashley uses 1/5 cup of vinegar. To make 2/3 of the recipe, we multiply the amount of vinegar needed for the full recipe by 2/3:
[tex]\[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{1}{5} \text{ cup} \times \frac{2}{3} \] \[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{1}{5} \times \frac{2}{3} \text{ cup} \] \[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{1 \times 2}{5 \times 3} \text{ cup} \] \[ \text{Vinegar for } \frac{2}{3} \text{ of the recipe} = \frac{2}{15} \text{ cup} \][/tex]
So, Ashley would use [tex]\(\frac{2}{15}\)[/tex] cup of vinegar to make 2/3 of her salad dressing recipe. Simplifying [tex]\(\frac{2}{15}\)[/tex] gives us [tex]\(\frac{2}{15} = \frac{2 \div 1}{15 \div 1} = \frac{2}{15}\)[/tex], which is already in its simplest form. Thus, the final answer remains [tex]\(\frac{2}{15}\)[/tex] cup of vinegar.
Write an expression in simplest form for the perimeter of a right triangle with leg lengths of 3a cubed and 4a cubed
Answer:
106.4622 [tex]a^{3}[/tex]
Step-by-step explanation:
Given the information:
A right triangleLeg lengths of [tex](3a)^{3}[/tex] and [tex](4a)^{3}[/tex]Use the pytagon theory to find the hypotenuse of the triangle
[tex]a^{2} + b^{2} = c^{2}[/tex]
<=>[tex]((3a)^{3}) ^{2} + ((4a)^{3}) ^{2} = c^{2}[/tex]
<=>[tex](3a)^{6} + (4a)^{6} = c^{2}[/tex]
<=> [tex]c^{2} = 4285a^{6}[/tex]
Take the square root of both sides
<=> c = 69.4622 [tex]a^{3}[/tex]
=> expression in simplest form for the perimeter of a right triangle is:
[tex](3a)^{3}[/tex] + [tex](4a)^{3}[/tex] + 69.4622 [tex]a^{3}[/tex]
= 27[tex]a^{3}[/tex] + 64[tex]a^{3}[/tex] + 69.4622 [tex]a^{3}[/tex]
= 106.4622 [tex]a^{3}[/tex]

The proportions of multiple samples of registered voters who vote are normally distributed, with a mean proportion of 0.38 and a standard deviation of 0.0485. What is the probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39
Answer:
B. 17%
Step-by-step explanation:
The probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 is given by the z-score and P ( 0.37 < x < 0.39 ) = 16.32 %
What is a z-score?The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.
The Z-score is calculated using the formula:
z = (x - μ)/σ
where z: standard score
x: observed value
μ: mean of the sample
σ: standard deviation of the sample
Given data ,
Let the probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 be P ( A )
Now , the mean of the sample μ = 0.38
The standard deviation σ = 0.0485
And , z₁ = 0.37 and z₂ = 0.39
So , P ( A ) = P ( 0.37 < x < 0.39 )
On simplifying , we get
z = (x - μ)/σ
z₁ = ( 0.37 - 0.38 ) / 0.0485
z₁ = -0.206
z₂ = ( 0.39 - 0.38 ) / 0.0485
z₂ = 0.206
So , P ( 0.37 < x < 0.39 ) = P ( -0.206 < z < 0.206 )
On further simplification of the z-score , we get
P ( 0.37 < x < 0.39 ) = 0.5816045 - 0.4183955
P ( 0.37 < x < 0.39 ) = 0.1632
Hence , the probability is 16.32 %

- 36 cm
O
290 cm?
360 cm?
3,960 cm
7,920 cm
Answer:
290 cm sq.
Step-by-step explanation:
We can approximate this irregular figure as a trapezoid.
We know the area formula for a trapezoid is A = (1/2)*(base1 + base2)*height
A = (1/2)* (22 cm + 36 cm) * (10 cm)
A = (1/2) *( 58 cm)*10 cm
A = 29 cm * 10 cm
A = 290 cm sq.

in the figure below ac and bd are diameters of circle p, what is the arc measure of bdc in degrees?
The arc measure BDC that subtend the angle at the center P of the circle is 213 degrees
How to find an angle of an arc in a circle?The arc measure of angle BDC is as follows;
AC and BD are the diameter of the circle.
∠BPD ≅ ∠APD
Therefore,
4k + 159 = 2k + 153
4k - 2k = 153 - 159
2k = -6
k = -6 / 2
k = -3
4(-3) + 159 = 147°
∠BPD ≅ ∠APD = 147°
Hence,
∠BPA ≅ ∠CPD = 33°

A worker's wage (w) is directly proportional to the number of hours (h) worked. If $71.25 is earned for working 5 h, how much is earned for working 23 h?
Answer:
The amount earned is $327.75
Step-by-step explanation:
If the workwr working for 5h gets $71.25, then his working for 1 hour could be said to be x.
5h = $71.25
1h = x; cross multiplying would result in
x= [tex]\frac{($71.25*1)}{5h}[/tex]
x= $14.25 which is the pay for 1h
Therefore for 23 h the worker would earn
23* 14.25 = $327.75

Francesca's window store made a mosaic for the community center. The mosaic had a 6 × 6 array of different color square tiles. If each tile is 2 1 4 ft long, what is the area of the whole mosaic?
The correct value of the length of a side = 2¼ ft
Answer:
area of the whole mosaic = 182.25 ft²
Step-by-step explanation:
We are told it has a 6 x 6 array of different colour square tiles.
Which means it has 6 x 6 = 36 square tiles.
Area of square = L²
Where L is length of side
Now, since length of one tile is 2¼ ft long.
Thus, area of one square tile = (2¼)²
= 81/16 ft²
Since there are 36 tiles,
Thus ;
Total area ; 81/16 x 36 = 182.25 ft²
Final answer:
The area of one tile in the mosaic is 5.0625 ft², and because there are 36 tiles in the mosaic, the total area is 182.25 ft². Mosaics are an ancient and durable art form requiring significant skill to create, especially when using small tesserae.
Explanation:
Francesca's window store created a mosaic for the community center that consisted of a 6 × 6 array of square tiles. To find the area of the whole mosaic, we need to calculate the area of one tile and then multiply it by the total number of tiles in the array.
Firstly, we have been given that each tile is 2 1/4 ft in length. Since the tiles are square, the area of one tile will be (2 1/4 ft) × (2 1/4 ft). In decimal form, 2 1/4 ft is equal to 2.25 ft. The area of one tile is therefore:
2.25 ft × 2.25 ft = 5.0625 ft²
Since there are 36 tiles (6 tiles in each direction), the total area of the mosaic will be:
5.0625 ft² × 36 = 182.25 ft²
Mosaics require considerable skill and time to create, especially when they employ tiny tesserae. As seen throughout history, mosaics have been used to decorate many surfaces, such as those in Francesca's example. The durability and artistic value of mosaics continue to make them a popular choice for artistic expression in structures like the community center.

The function f(x)is graphed above. Which of the graphs below represents the function g(x)=(x+1)^2
Answer:
The function g(x) = (x + 1)² is represented by the graph Y
Step-by-step explanation:
The question presents the graph of the function x² above
Therefore, for a function f(x) = x² at x = 0 y = 0
For function g(x) = (x + 1)² when x = 0 g(x) = 1 Satisfied by graph W and Y
Also we have g(x) = (x + 1)² = x² + 2·x + 1 or g(x) = f(x) + 2·x + 1
We find the minimum of the graph by differentiating and equating to zero as follows;
[tex]\frac{\mathrm{d} (x + 1)^{2}}{\mathrm{d} x} = 2x +2 = 0[/tex]
Therefor, the minimum is at x = -1 satisfied by only graph Y
Hence the graph that represents the function g(x) = (x + 1)² is the graph Y.

Solve 6 +5(m + 1) = 26.
Answer:
m = 3
Step-by-step explanation:
First, distribute the 5 to the values inside the parentheses.
6 + 5m + 5 = 26
Combine like terms: 5m + 11 = 26
Then, you want to isolate the variable so you subtract 11 from both sides because what you do on one side must be done to the other.
5m + 11 - 11 = 5m
26 - 11 = 15
5m = 15
Then divide both sides by 5.
5m / 5 = m
15 / 5 = 3
m = 3
Answer:
m=3
