Answer:

\(\bold{x = \dfrac{8}{9}}\)

Step-by-step explanation:

We have to rewrite the below as simplified fraction.

\(\large{0.\overline{8} = {?}}\)

Solution:

Let \(x =0.\overline 8\) which means \(x =0.888888.......\)

Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.

To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.

So, we can rewrite \(x\) as:

\(x =0.8\overline8\) ......(1)

Now, let us multiply the above with 10.

\(10x = 0.8\overline 8 \times 10\\\Rightarrow 10 x= 8.\overline8\) ....... (2)

Now, let us subtract (1) from (2):

\(10x-x=8.\overline8 - 0.\overline8\\\Rightarrow 9x = 8\\\Rightarrow \bold{x = \dfrac{8}{9}}\)

So, in simplified fractions:

\(\large{0.\overline{8} = \bold{\dfrac{8}{9}}}\)

Answer: Since triangle QRS and triangle TUV are both triangles, we can use the fact that the sum of the interior angles in a triangle is 180 degrees.

In triangle QRS, the measure of angle Q is 117 degrees and the measure of angle R is 180 - 117 = 63 degrees. The measure of angle S is 180 - 63 = 117 degrees, since the angles in a triangle add up to 180 degrees.

In triangle TUV, the measure of angle T is 180 - 30 = 150 degrees and the measure of angle U is 30 degrees. The measure of angle V is 180 - 150 = 30 degrees, since the angles in a triangle add up to 180 degrees.

The measures of LQ and LS can be found using the fact that the exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it.

The measure of LQ is equal to the sum of the measures of angles R and T:

LQ = 63 + 150 = 213 degrees

The measure of LS is equal to the sum of the measures of angles Q and U:

LS = 117 + 30 = 147 degrees

So the measure of LQ is 213 degrees and the measure of LS is 147 degrees.

Step-by-step explanation:

For 2 1/4 hours he mows 1/2 of an acre

I know that 1/4 of an hour is 15 minutes so I added 2 hours and 14 minutes 4 times to get 9 hours.

Now I know 2 1/4 of an hour times 4 equals 9 hours

1/2 an acre times 4 equals 2

Olivia will have a total of $1020.10 in her account after two years.

After the first year, the initial deposit of $1000 will earn 1% interest, which is $10. So, after one year, Olivia's account balance will be $1010.

After the second year, the balance of $1010 will earn 1% interest again. The formula to calculate the balance after two years is:

Balance after two years = Initial deposit × (1 + interest rate)^2

Plugging in the values, we get:

Balance after two years = $1000 × (1 + 0.01)^2 = $1020.10

Therefore, Olivia will have a total of $1020.10 in her account after two years.

$91.80 will be deducted from Mark's gross earnings for Social Security and Medicare taxes.

The Social Security tax rate for 2021 is 6.2% and the Medicare tax rate is 1.45%. To find the amount that must be withheld from Mark's gross earnings, we can use the following calculations:

Social Security tax = 6.2% of $1,200 = 0.062 x $1,200 = $74.40

Medicare tax = 1.45% of $1,200 = 0.0145 x $1,200 = $17.40

The total amount that will be deducted from Mark's earnings for Social Security and Medicare taxes is the sum of these two amounts:

Total = $74.40 + $17.40 = $91.80

Therefore, $91.80 will be deducted from Mark's gross earnings for Social Security and Medicare taxes.

The equation of the line that passes through (1, 2) and is parallel to the line whose equation is 4x + y - 1 = 0 is  4x+y-6=0.

The line's equation is expressed in slope-intercept form: y = mx + b, where m represents the slope and b represents the y-intercept.

The slope intercept form is used to calculate the y-intercept and slope of a straight line.

We know that the equation of the line is, y= mx +b

4x+y-1=0 is the same as y= -4x+1

For this equation, b=1, but for a line with slope -4 passing through the point (1,2), the y-intercept changes.

y= -4x+b

The above line is passing through the point (1, 2)

2=-4(1)+b

Now, we have to solve for b value we get b=6.

The equation that we get is,

y= -4x+6 or 4x+y-6=0.

The equation of the line that passes through (1, 2) and is parallel to the line whose equation is 4x + y - 1 = 0 is  4x+y-6=0.

The law of conservation of energy and momentum can be used to construct the equation that connects the initial release height of block x (hx) and the speed of the two-block system following the collision (v s).

Block x's initial kinetic energy (0.5 * m x * v x2) and potential energy (m x * g * hx) are both equal to the total kinetic energy of both blocks after the collision (0.5 * (m x + m y) * v s).

Combining everything, we get the following equation:

m x * g * hx + 0.5 * m x * v x2 = 0.5 * (m x + m y) * v s2.

where g is the acceleration brought on by gravity, v x is the starting speed of block x, and m x and m y are the masses of blocks x and y.

Answer:

About 100 times faster

=1 x 10²

Step-by-step explanation:

Estimate using a single digit times a power of 10.

We approximate to the nearest whole number

A healthy human heart beats about 1,533,000 times in a year.

= 1.533 × 10⁶

As a single digit = 2.0 × 10⁶

A sparrow's heart beats about

241,776,000 times in a year.

= 2.41776 × 10⁸

As a single digit = 2 × 10⁸

About how many times faster does the sparrow's heart beat compared to the human heart?

We find the difference in their powers of 10

The real numbers can be classified as either rational or irrational numbers.

1. Rational Numbers:
Rational numbers can be expressed as the ratio (or fraction) of two integers. They can be written in the form p/q, where p and q are integers and q is not equal to zero. Rational numbers can be positive, negative, or zero. Some examples of rational numbers include 1/2, -3/4, and 5.

2. Irrational Numbers:
Irrational numbers cannot be expressed as the ratio of two integers. They are non-repeating and non-terminating decimals. Irrational numbers can be positive or negative. Some examples of irrational numbers include √2, π (pi), and e (Euler's number).

It is important to note that the set of real numbers contains both rational and irrational numbers. Every rational number is a real number, but not every real number is a rational number. This means that there are real numbers that cannot be expressed as a fraction.

In summary, the classification of real numbers as rational or irrational depends on whether they can be expressed as a ratio of integers (rational) or not (irrational). The set of real numbers contains both rational and irrational numbers, providing a comprehensive representation of all possible values on the number line.

The given statement "if you’re comparing the test scores between two groups, you should use a one-sample z-test." is False because you should use two-sample t-test.

If you are comparing the test scores between two groups, you should use a two-sample t-test. A one-sample z-test is used to compare a sample mean to a known population mean when the population standard deviation is known.

However, in most cases, the population standard deviation is unknown, and the sample size is typically small, so a t-test is preferred. The two-sample t-test is used to compare the means of two independent groups. The test assumes that the samples are normally distributed and have equal variances.

If the variances are unequal, a modified version of the t-test called the Welch's t-test should be used. In summary, the appropriate test to use depends on the nature of the comparison being made, the sample size, the distribution of the data, and whether the variances of the two groups are equal or not.

Answer:

Answer:

It’s 60 because one cube equal 12

And like there is 5 cubes it will be 12x5

Which equals 60

Step-by-step explanation:

The parametric equations for the line of intersection are:
x = 61 - 5t
y = 2t - 30
z = t

To find the parametric equations for the line of intersection of the given planes, we first need to solve the system of equations:

1. x + 2y + z = 1
2. 2x + 5y + 32 = 4

Step 1: Solve for x from equation 1:
x = 1 - 2y - z

Step 2: Substitute x in equation 2 with the expression found in step 1:
2(1 - 2y - z) + 5y + 32 = 4

Now we can use elimination to solve for one variable. Let's eliminate y by multiplying the first equation by 5 and subtracting it from the second equation:

Step 3: Simplify and solve for y:
2 - 4y - 2z + 5y + 32 = 4
y - 2z = -30

Step 4: Designate z as the parameter t:
z = t

Step 5: Substitute z with t in the expression for y:
y = 2t - 30

Step 6: Substitute z with t in the expression for x:
x = 1 - 2(2t - 30) - t
x = 1 - 4t + 60 - t
x = 61 - 5t

Now we have the parametric equations for the line of intersection:
x = 61 - 5t
y = 2t - 30
z = t

Note that we can choose any value of z for the parameter t, since z is unconstrained.
