The Volume of each bead is approximately 1.767 mm^3 when rounded to the nearest tenth.

The volume of each bead, the volume of a sphere using its diameter. The formula for the volume of a sphere is given by:

V = (4/3) * π * r^3

where V is the volume and r is the radius of the sphere.

Given that the diameter of each bead is 1.5 millimeters, we can calculate the radius as half of the diameter:

r = 1.5 mm / 2 = 0.75 mm

Now, we can substitute the value of the radius into the volume formula:

V = (4/3) * π * (0.75 mm)^3

Using the value of π ≈ 3.14 and performing the calculations:

V ≈ (4/3) * 3.14 * (0.75 mm)^3

V ≈ (4/3) * 3.14 * 0.421875 mm^3

V ≈ 1.767 mm^3 (rounded to the nearest tenth)

the volume of each bead is approximately 1.767 mm^3 when rounded to the nearest tenth.

The similar shapes EFGH and JKLM have the measurement of angle Z equal to 65°, the length x = 27.5 and the length of y = 12

Similar shapes are two or more shapes that have the same shape, but different sizes. In other words, they have the same angles, but their sides are proportional to each other. When two shapes are similar, one can be obtained from the other by uniformly scaling (enlarging or reducing) the shape.

Given that the shape EFGH is a smaller shape of JKLM, and they are similar, then:

the measure of angle Z is equal to 65°

the side EF corresponds to JK and side FG corresponds to KL, so:

8/20 = 11/x

x = (11 × 20)/8 {cross multiplication}

x = 27.5

the side EF corresponds to JK and EH corresponds to JM, so:

8/20 = y/30

y = (30 × 8)/20 {cross multiplication}

y = 12

Therefore, the similar shapes EFGH and JKLM have the measurement of angle Z equal to 65°, the length x = 27.5 and the length of y = 12

Answer:21 obviously it’s actually (19) don’t tell anyone

Step-by-step explanation:

Answer:

x=112

Step-by-step explanation:

First, let's get all of the fractions to a common denominator.

Based on the numbers given (8,56, and 7), let's make all of the denominators be 56

for \(\frac{-7}{8} x\), multiply the numerator and denominator by 7.

\(\frac{-7x}{8}\)×\(\frac{7}{7}\)= \(\frac{-49}{56} x\)

we can leave \(\frac{-5}{56}x\) as it is

and for \(\frac{1}{7} x\), we cam multiply the numerator and denominator by 8

\(\frac{1x}{7}\)×\(\frac{8}{8}\)=\(\frac{8x}{56}\)

Here's the equation now:

\(\frac{-49x}{56}\)-\(\frac{5x}{56}\)+\(\frac{8x}{56}\)=-92

now simlify the fractions

numerators:

-49x-5x+8x=-46x

here's the fraction now:

\(\frac{-46x}{56}\)=-92

We can simplify the fraction by 2 so it's \(\frac{-23x}{28}\)

\(\frac{-23x}{28}\)=-92

now multiply both sides by \(\frac{28}{-23}\), which is the reciprocal of \(\frac{-23}{28}\) (to isolate the variable)

\(\frac{28}{-23}\)×\(\frac{-23x}{28}\)=-92×\(\frac{28}{-23}\)

\(\frac{-92*28}{-23}\)

x=112

Hope this helps!

Answer:

x = 112

Step-by-step explanation:

The common denominator is 56 because 8*7 is 56

\(-\frac{7*7*x}{8*7} -\frac{5*x}{56}+\frac{8*x}{56} = - 92 \\-\frac{49*x}{56} -\frac{5*x}{56}+\frac{8*x}{56} = - 92 \\\frac{-46*x}{56}=-92\)

Multiply both sides by 56

-46*x = -92 * 56

-46*x = -5152

Divide by - 46

x = -5152/-46

x = 112

a. To create an exponential model for new cases in terms of days, we can use the formula: y = a * b ^ x, where y is the number of new cases, x is the number of days since the first observation, and a and b are constants that we need to determine. Using the two data points given, we can set up a system of equations:

235 = a * b ^ 0

395 = a * b ^ 10

Solving for a and b, we get:

a = 235

b = (395/235)^(1/10) = 1.067

Therefore, the exponential model for new cases in Milwaukee is:

y = 235 * 1.067 ^ x

b. To find the number of new cases on Oct. 31, 2020, we need to plug in x = 19 (since Oct. 31 is 19 days after Oct. 12) into the model:

y = 235 * 1.067 ^ 19 = 1018.5

Therefore, based on the exponential model, we would expect around 1019 new cases on Oct. 31, 2020.

c. The actual number of new cases on Oct. 31, 2020, was 1043. This is higher than the predicted value of 1019, but not by a huge margin. Overall, the model seems to fit the data reasonably well, especially considering that there are many factors that can affect the number of new cases in a given area, and that the model is based on only two data points. However, it is worth noting that the exponential model assumes that the growth rate of new cases remains constant over time, which may not be a realistic assumption in the long run.

For example, the first one says that:

h(8) = 21

But this is false, because we already know that h(8) = 19.

Answer:

Step-by-step explanation:

To use the 68-95-99.7 Empirical rule, we need to convert the given prices to standard deviations from the mean using the formula:

z = (x - mu) / sigma

where:

x = the given price

mu = the mean price

sigma = the standard deviation

Once we have calculated the z-scores, we can use the Empirical rule to find the percentage of buyers who paid within a certain range of prices.

For the range of Ksh 3050000 and 3650000:

First, we need to calculate the z-scores for these two prices:

z1 = (3050000 - 3500000) / 150000 = -0.3

z2 = (3650000 - 3500000) / 150000 = 1.0

According to the Empirical rule, about 68% of the buyers paid within one standard deviation of the mean, about 95% paid within two standard deviations, and about 99.7% paid within three standard deviations.

Since z1 is -0.3 and z2 is 1.0, both of these z-scores fall within one standard deviation of the mean. Therefore, we can estimate that about 68% of buyers paid between Ksh 3050000 and 3650000 for this car model.

For the range of Ksh 3200000 and 3350000:

Again, we need to calculate the z-scores for these two prices:

z1 = (3200000 - 3500000) / 150000 = -0.2

z2 = (3350000 - 3500000) / 150000 = -1.0

Both of these z-scores fall within one standard deviation of the mean, so we can again estimate that about 68% of buyers paid between Ksh 3200000 and 3350000 for this car model.

Therefore, the percentage of buyers who paid between Ksh 3050000 and 3650000 is about 68%, and the percentage of buyers who paid between Ksh 3200000 and 3350000 is also about 68%.

According to the properties of the standard normal distribution, approximately 99.7% of the values lie within three standard deviations of the mean. Therefore, the answer is 99.7%.

To determine the percentage of videos on the streaming site that are between 264 and 489 seconds, we need to calculate the area under the normal curve within that range. Since the distribution is approximately normal with a mean of 264 seconds and a standard deviation of 75 seconds, we can use the properties of the standard normal distribution to find the desired percentage.

First, we need to convert the values 264 and 489 to z-scores, which represent the number of standard deviations a particular value is away from the mean. The z-score formula is given by:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get:

z1 = (264 - 264) / 75 = 0

z2 = (489 - 264) / 75 = 3

Next, we can use a standard normal distribution table or a calculator to find the area under the curve between z = 0 and z = 3. The area represents the percentage of videos falling within that range. The answer is 99.7% .

The solution is, the value of the variables are x = 40 and, y = 160.

Notice that "x" and "3x+20" are supplementary angles so their sum is 180°

(x) + (3x + 20) = 180

4x + 20 = 180

4x = 160

x = 40

To solve for "y", you have 2 options: either notice that "x" and "y-20" are supplementary angles so their sum is 180° or notice that "3x + 20" and "y - 20" are vertical angles so are equal to each other. I am going to solve using the first option because it is less work.

(x) + (y - 20) = 180°

40 + y - 20 = 180

y + 20 = 180

complete question:

Find the value of each variable

Answer:

When solving an inequality, we must be careful when multiplying or dividing by a variable because doing so can change the direction of the inequality.

For example, consider the inequality:

2x < 6

If we divide both sides by 2, we get:

x < 3

This is the correct solution. However, if we had instead divided both sides by x, we would get:

2 < 6/x

which is not equivalent to the original inequality. To understand why, we can consider two cases:

If x is positive, then dividing both sides by x will preserve the direction of the inequality. However, if x is negative, dividing by x will reverse the direction of the inequality.

If x is zero, then we cannot divide by x, because division by zero is undefined.

In general, when solving inequalities involving variables, it is safer to use algebraic manipulation rules that do not involve multiplying or dividing by variables. These rules include adding or subtracting the same value from both sides, multiplying or dividing both sides by a constant (as long as the constant is positive), and using properties of inequalities such as the transitive property and the addition and multiplication properties.

Answer: x = 8, x = -2

Step-by-step explanation:

(x - 3)² = 25

Step 1: Take the square root on each side of the equation.

(x - 3)² = 25

√(x - 3)² = ±√25

Step 2: After taking the square root on each side of the equation, this allows you to solve for x.

x - 3 = ±5

Solution 1

x - 3 = 5

x = 5 + 3

x = 8

Solution 2

x - 3 = - 5

x = -5 + 3

x = -2

Another way to solve this problem is to multiply (x - 3)² using the FOIL methods (first, outer, inner, last) and then set it equal to 25.

(x - 3) (x - 3) = 25

x² - 3x - 3x + 9 = 25

The next step is to add like terms. After adding like terms, solve for x.

x² - 3x - 3x + 9 = 25

x² - 6x + 9 - 25 = 25 - 25

x² - 6x - 16 = 0

Last step is to factor x² - 6x - 16 = 0 so you can solve for the two solutions.

(x - 8) (x + 2) = 0

Solution 1

x - 8 = 0

x = 8

Solution 2

x + 2 = 0

x = -2
