lliana’s math grade increased from 65 to 86. Fiona’s math grade increased from 70 to 80. What is the difference, rounded to the nearest whole number, between the approximate percent increases?

Answers

Okay. Let us do it surgically. Let us solve first the rate of increase in Lliana's Math grade. 86-65 = 21, thus the rate can be written as a fraction 21/65. We will reserve the decimal form once we are done with both rates of increase.

On the same note, Fiona's increase in Math grade is determined by subtracting 70 from her recent grade of 80, thus giving us an increase in her grade by 10. Therefore, the rate of increase in her Math grade is 10/70.

Now, let us take the decimal forms of the students' grade in math respectively. Lliana's is 21/65 or 0.32307692307... Fiona's is 10/70 or 0.14285714285. Now, subtracting this decimals we have 0.18021978021.
Changing it to percent form, we must multiply it by 100 and add the symbol "%". Therefore, we have 18.021978021 %.

Finally, rounding the value to the nearest whole number, we obtained 18.00% or just 18%.

The formula for glue says to add 55 mL of hardener to each container of resin. How much hardener should be added to 16 containers of resin? Write your answer in liters.

Answers

Final answer:

To determine how much hardener is required for 16 containers of resin, multiply 55 mL by 16 to get 880 mL, and then convert this to liters by dividing by 1,000, resulting in 0.88 liters of hardener needed.

Explanation:

To determine how much hardener should be added to 16 containers of resin, we must multiply the amount needed for one container by the number of containers. The formula given states that 55 mL of hardener is required for each container of resin. To find the total amount for 16 containers, we perform the following multiplication:

Calculate the total milliliters needed: 55 mL/container × 16 containers = 880 mL.Convert the total milliliters to liters:
Since 1 liter is equivalent to 1,000 milliliters, divide the total milliliters by 1,000 to get the volume in liters. 880 mL ÷ 1,000 = 0.88 L.

Therefore, 0.88 liters of hardener should be added to 16 containers of resin.

Final answer:

To determine the amount of hardener needed for 16 containers of resin, multiply 55 mL by 16 to get 880 mL and then convert that to liters, resulting in 0.88 liters of hardener.

Explanation:

To find out how much hardener should be added to 16 containers of resin, where each container requires 55 mL of hardener, you need to do a simple multiplication operation. Multiply the amount of hardener needed for one container by the number of containers:

Multiply 55 mL by 16:Now, convert milliliters to liters. Since there are 1,000 milliliters in a liter:

Therefore, you should add 0.88 liters of hardener to the 16 containers of resin.

Simplify the expression. (2x^2y)^3

Answers

Answer:

8x6y3 3 and six put at top between y and and three

Sure, I'd be happy to show you how to simplify this expression. Here are the steps:

1. In this expression, we have three numbers that are being multiplied together, 2, x^2, and y, and the entire product is raised to the power of 3.

2. Let's take each part of the product individually and raise them to the power of 3.

For the first part, 2 raised to the power of 3: this gives us 8, since 2 * 2 * 2 equals 8.

3. The next part is [tex]x^2[/tex] raised to the power of 3. When raising a power to another power, we multiply the powers together. Therefore, (x^2)^3 becomes x^(2*3), which can be simplified to x^6.

4. Finally, y raised to the power of 3 remains as y^3.

5. So, when we put together all three parts, we obtain the simplified expression, and (2x^2y)^3 simplifies to 8x^6y^3.

So, the simplified expression for (2x^2y) ^3 is 8x^6y^3.

The range is? is the same for both
is greater for data set 1
is greater for data set 2
The mean? is the same for both
is greater for data set 1
is greater for data set 2

Answers

Answer:

is greater for data set 2 ; is greater for data set 2

Step-by-step explanation:

The range is found by subtracting the highest and lowest value. The range of the first plot would be

34-21 = 13.

The range of the second plot would be

36-12 = 24.

The mean is found by adding together all of the data points and dividing by the number of data points. For the first plot, the sum of the data is 274 and there are 10 data points; this makes the mean 274/10 = 27.4.

For the second plot, the sum of the data is 280.5 and there are 10 data points; this makes the mean 280.5/10 = 28.05.

The range is greater for data set 2.

Then mean is greater for data set 2.

What is Mean?

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Consider the data plot for 13 to 15 years olds.

Mean = Average of the values

= (21 + 24 + 26 + 27 + 27 + 28 + 28 + 28 + 31 + 34) / 10

= 27.4

Range = Maximum value - Minimum value

= 34 - 21

= 13

Consider the data plot for 16 to 18 years olds.

Mean = Average of the values

= (12 + 21 + 28 + 28 + 28 + 28 + 30.5 + 34 + 35 + 36) / 10

= 28.05

Range = Maximum value - Minimum value

= 36 - 12

= 24

Hence the range and mean are greater for data set 2.

[tex]v_{f}[/tex] is the final speed

We know from our problem that increases his speed from 5 m/s to 15 m/s in 10 seconds, so his initial speed is 5 m/s and his final speed is 15 m/s; therefore, [tex]v_{i}=5[/tex], [tex]v_{f}=15[/tex], and[tex]t=10[/tex]. Lets replace those values in our formula:

How far are 27 and -54 apart on the number line?

Solution:

If we see on the number line , 27 is 27 units apart from 0 and it is 27 units to the right of 0

And, -54 is 54 units apart from 0 and it is 54 units to the left of 0. So, -54 is in opposite direction with respect to 27.

So, To find how far is 27 from -54 we must add 27 and 54

As, 27+54=81

So, -54 and 27 are 81 units away from each other.

Brandy has a strike rate of 6 out of 10 frames. So the probability that Brandy will make a strike is 6/10 = 0.6. So, if Brandy has one roll in the first frame of the next game , the probability he will have a strike is 0.6 or 60%.

It 5/10 probability and 5/10 simplified is 1/2

Final answer:

The experimental probability of Brandy rolling a strike in the first frame of the next game is 1/2.

Explanation:

To find the experimental probability that Brandy will roll a strike in the first frame of the next game, we need to divide the number of times Brandy rolled a strike in the first frame by the total number of frames. In this case, Brandy rolled a strike in 5 out of 10 frames, so the experimental probability is 5/10, which simplifies to 1/2.

From the graph, when x = 0, y = 300, hence the y-intercept is of b = 300. The amount decays to 0 when the x-intercept is of x = 450, hence the slope is given by:
