The true statements would be; A) If b = 6 ft, then he needs 52 feet of fencing. and B) If b = 8 ft, then he needs 56 feet of fencing.
What is perimeter?Its the sum of length of the sides used to made the given figure.
To find the amount of fencing material needed, we will find the perimeter of the fence
The perimeter of the fence = 2(L+W)
L is the length, W is the width
Given
Length = 20feet
Width = b feet
The perimeter of the fence = 2(20+b)
perimeter of the fence = 2(20) + 2b
perimeter of the fence = 40+2b cm
Hence the amount of material needed would be (40+2b)cm
So we can say that 2 sides equal 20 feet each. The Total being 40 feet
So we take each B and multiply them by 2 for the two sides it shall equal.
6*2=12
8*2=16

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
How can I find the cube root of 64?
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

The time for 22 leg-press reps is 11.9 seconds.
Step-by-step explanation:The lines of best fit is the trend line of the dataset.
The equation of line of best fit is y = 0.120x + 9.274The time for 22 leg-press reps is 11.9 seconds(A) The equation of the line of best fitThe table is given as —
(x) : 12 32 7 26 28 15 1
(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5
To determine the equation of line of best fit, we make use of a regression calculator.
Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)
(B) The number of seconds for 22 leg-press repsThis means that x = 22.
So, we have:
y = 0.120 * 22 + 9.274
= 2.640 + 9.274
= 11.914
(Approximate to the nearest hundredths)
= 11.9
Hence, the time for 22 leg-press reps is 11.9 seconds.

Let f(x)=2/3x+4 and g(x)=kx+6 . For which value of will the x-intercept of f() be equivalent to the x-intercept of g()?
0=(2/3)x +4
multiply by 3
0=2x +12
x =-6
(2/3)x +4 =0
2x +12 = 0
x =-6 = the x intercept
(2/3)x + 4 = kx +6
(2/3- k)x = 2
multiply by 3
(2-3k)x = 6
(2-3k)(-6) = 6
2-3k =-1
3k= 3
k = 1 makes the 2nd equation have the same x intercept = -6 or the point (-6,0)
7th grade - Find the surface area of this trapezoidal prism. Please help ASAP I'll give brainliest!!!
Answer:
\(380 \text{ m}^2\)
Step-by-step explanation:
To find the surface area of the trapezoidal pyramid, we can use the formula:
\(SA = 2(b) + (p \cdot d)\),
where \(b\) is the area of the base, \(p\) is the perimeter of the base, and \(d\) is the prism's depth.
First, we should find the area of the base using the area of a trapezoid formula.
\(A_\text{trap} = \dfrac{b_1 + b_2}{2} \cdot h\)
\(b = \dfrac{15 + 5}{2} \cdot 7\)
\(b = 10 \cdot 7\)
\(b = 70 \text{ m}^2\)
Now, we can plug the given dimensions along with the base area into the surface area formula.
\(SA = 2(b) + (p \cdot d)\)
\(SA = 2(70) + ([15 + 10 + 5 + 10] \cdot 6)\)
\(SA = 140 + (40 \cdot 6)\)
\(SA = 140 + 240\)
\(\boxed{SA = 380 \text{ m}^2}\)
how many glasses did she make
First, we need to find how many liters of horchata Ana has in her refrigerator:
7/10 of a liter is the same as (7/10) / (1/1) = 7/10 liters.
To find how many glasses of horchata she can pour, we divide the total amount of horchata by the amount in each glass:
(7/10) ÷ (1/8) = (7/10) x (8/1) = 56/10 = 5.6
Ana can pour 5.6 glasses of horchata. Since she cannot pour a fraction of a glass, she can pour a maximum of 5 glasses of horchata.

Step-by-step explanation:
the correcto anwar
es pero que te cirba
Answer:
The best prediction is that you will pick a green marble approximately 7 times and an orange marble approximately 5 times.
Step-by-step explanation:
If there are 5 orange marbles and 7 green marbles out of a total of 48 marbles, the best prediction for the number of times you will pick a green or an orange marble would still be proportional to the ratio of green and orange marbles.
The ratio of green marbles to the total number of marbles is 7/48, and the ratio of orange marbles to the total number of marbles is 5/48.
To predict the number of times you will pick a green marble, you can multiply the total number of selections (48) by the ratio of green marbles:
48 * (7/48) = 7
Similarly, to predict the number of times you will pick an orange marble:
48 * (5/48) = 5
Therefore, the best prediction is that you will pick a green marble approximately 7 times and an orange marble approximately 5 times.
