used 5/6 yard of ribbon in her dress.
Which girl used more ribbon?
How much more did she use?
Answers
Answer:
Jasmine;
\(\frac{1}{18}\) more
Step-by-step explanation:
Amie used 7/9 yard of ribbon, and Jasmine used 5/6 yard of ribbon. We can compare these fractions easier if they have the same denominator (bottom number). Let's get a common denominator for these fractions.
7/9 x 2/2 = 14/18
Amie used 14/18 yards of ribbon
5/6 x 3/3 = 15/18
Jasmine used 15/18 yards of ribbon
Which is greater: 14/18 or 15/18? 15/18
To find out how much more, just subtract 14/18 from 15/18:
15/18 - 14/18 = 1/18
Jasmine used 1/18 yards more ribbon than Amie

Answers
Answer:
Option B
Step-by-step explanation:
The question can be solved without observing the masses and calculating them.
How?
Periodic table law states that masses get increased in group and get decreased in period.Hydrogen is the 1st element so it has least mass.Now
Only option B and D has Hydrogen at first.

Given SSxx is 950 and SSxy is 205.2. Calculate and interpret the value of r if the data
consist if 12 number of samples with y = 120 and Σy² = 2028
Answers
Step-by-step explanation:
To calculate the correlation coefficient (r) given SSxx, SSxy, and other information, we need to use the following formula:
r = √(SSxy / SSxx)
Given SSxx = 950 and SSxy = 205.2, we can substitute these values into the formula:
r = √(205.2 / 950)
Calculating the value:
r = √(0.216)
r ≈ 0.465
The correlation coefficient (r) is approximately 0.465.
Interpretation: The correlation coefficient measures the strength and direction of the linear relationship between two variables. In this case, the value of r = 0.465 indicates a positive linear relationship between the variables, but it's not a strong relationship. The closer the value of r is to 1 or -1, the stronger the relationship. Since r = 0.465 is relatively close to zero, it suggests a weak positive linear association between the variables being an analyzed.
hope it help you
The Pearson's correlation coefficient (r) based on given data is approximately 0.44, implying a moderate positive correlation.
Explanation:The formula for calculating Pearson's correlation coefficient (r) in this case is given as: r = SSxy / sqrt(SSxx * SSyy). However, we don't have the value for SSyy directly, but we can calculate it. We know that SSyy = Σy² -(Σy)² / n. Given that Σy² is 2028 and Σy is 120 and number of samples n is 12, we can calculate SSyy as: SSyy = 2028 - (120)² / 12 = 52. Now, substitute SSxx = 950, SSxy = 205.2 and SSyy = 52 in the formula to find r: r = 205.2 / sqrt(950 * 52), giving us an r-value of approximately 0.44. This value of r suggests a moderate positive correlation between the variables in the dataset.

Based on the diagram, we can see that the triangle formed by the line segment with length 8 and the two dashed line segments is a right triangle with a 45° angle. This means that the other two angles of the triangle are also 45° each.
Using the properties of 45°-45°-90° triangles, we know that the length of the hypotenuse is equal to the length of either leg times the square root of 2. Therefore, we have:
x = 8 / sqrt(2) = 8 * sqrt(2) / 2 = 4 * sqrt(2)
So the value of x is option B: 8√2 / 2 or simplified, 4√2.

The gate of a stadium ha two pillars each of height 10ft.with four visible lateral faces and 3ft*3ft bases .the top of eaxh pillar has combined pyaramid of height2ft.If the combined structures of both pillars and pyramid are painted at the rate of rs 80 persq.ft.calcuate the total cost of painting.
Answers
The pillars and the pyramids in the stadium gate means that we have to calculate the area of the items that make up the gate one after the other. At the end of the calculation, the calculated areas are then added up.
The total cost of painting is Rs.21344
First, we calculate the area of 1 side of 1 pillar using:
\(A = Height * Base\)
Where
\(Height = 10ft\) --- Height of the pillar
\(Base = 3ft\) --- Base of the pillar
So:
\(A = 10ft * 3ft\)
\(A = 30ft^2\)
The area of the 4 sides of the pillar is:
\(A_2 = 4 * A\) --- i.e. 4 multiplied by the area of 1 side
\(A_2 = 4 * 30ft^2\)
\(A_2 = 120ft^2\)
The area of the 2 pillars is:
\(Area_1 = 2 * A_2\) --- i.e. 2 multiplied by the area of 1
\(Area_1 = 2 * 120ft^2\)
\(Area_1 = 240ft^2\)
Because one part of the pyramid won't be visible, we calculate the area of the pyramid using:
\(Area = lw + l\sqrt{(w/2)^2 + h^2} + w\sqrt{(l/2)^2 + h^2}\)
Where:
\(h = 2\) -- the height
\(l = w = 3\) --- the base of the pillar is the length & width of the pyramid.
So, we have:
\(Area = 3\sqrt{(2/2)^2 + 2^2} + 3\sqrt{(2/2)^2 + 2^2}\)
\(Area = 3\sqrt{1 + 4} + 3\sqrt{1 + 4}\)
\(Area = 3\sqrt{5} + 3\sqrt{5}\)
\(Area = 6\sqrt{5}\)
For the two pyramids, the area is:
\(Area_2 = 2 * 6\sqrt 5\) -- 2 multiplied by area of 1
\(Area_2 = 12\sqrt 5\)
\(Area_2 = 26.8\)
So, the total area to be painted is:
\(Total = Area_1 + Area_2\) --- the sum of the area of the pillars and the pyramids
\(Total = 240+26.8\)
\(Total = 266.8ft^2\)
The unit cost of paint is:
Rate = Rs80 per sq.ft
The total cost of painting is:
\(Cost = 80 * 266.8\)
\(Cost = Rs.21344\)
Hence, the total cost of painting is Rs.21344.

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes
How many minutes of the ride are spent higher than 28 meters above the ground?The radius of the Ferris wheel is 30 / 2 = 15 meters.
The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.
The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.
The angle between these two positions is 180 degrees.
The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Step-by-step explanation:
the question can be represented with:
12.5/5 and x/3
12.5/5 is 2.5, so that means each bag of dog food is $2.5
So then you multiply 2.5 by 3, = 1.20, so 3 bags of dog food is $7.50.
Answer:
Step-by-step explanation:
Remark
I take it you mean 5 and not 0.5.
If that is the case, this is a proportion question. A proportion consists of 4 parts. If you know 3 of the parts, you can solve for the 4th one.
Formula
Number of bags/Cost = new number of bags/Cost of the new number
Givens
original Number of bags = 5
Cost = 12.50
New number of bags = 3 bags
Cost = x
Solution
5/12.50 = 3/x Cross Multiply
5x = 12.50 * 3 Combine the right
5x = 37.5 Divide by 5
5x/5 = 37.5/5
x = 7.5

Elena receives $95 per year in simple interest from three investments totaling $2100 . Part is invested at 3%, part at 4%, and part at 5%. There is $1000 more invested at 5% than at 4%. Find the amount invested at each rate.
The amount invested at 3% is $
the amount invested at 4% is $
and the amount invested at 5% is $
Answers
The amount invested at 3% is $400, the amount invested at 4% is $700, and the amount invested at 5% is $1000.
Let's assume the amount invested at 4% is x dollars.
According to the given information, the amount invested at 5% is $1000 more than the amount invested at 4%.
So, the amount invested at 5% is (x + $1000).
The total amount invested is the sum of the amounts invested at each rate, which is $2100.
Therefore, we can write the equation:
x + (x + $1000) + (amount invested at 3%) = $2100
Now, we can calculate the amount invested at 3%.
We subtract the sum of the amounts invested at 4% and 5% from the total investment:
(amount invested at 3%) = $2100 - (x + x + $1000) = $2100 - (2x + $1000)
Given that Elena receives $95 per year in simple interest from the investments, we can use the formula for simple interest:
Simple Interest = Principal × Interest Rate
The interest earned from the investment at 3% is (amount invested at 3%) × 0.03, the interest earned from the investment at 4% is (amount invested at 4%) × 0.04, and the interest earned from the investment at 5% is (amount invested at 5%) × 0.05.
According to the problem, the total interest earned is $95.
So we can write the equation:
(amount invested at 3%) × 0.03 + (amount invested at 4%) × 0.04 + (amount invested at 5%) × 0.05 = $95
Now we can substitute the expression for (amount invested at 3%) and solve for x.
Once we have the value of x, we can calculate the amounts invested at 3%, 4%, and 5% using the given information.
