What is the quotient of 4 over 5 divided by 3 over 4?

The expression becomes 3log₁₀2-3log₁₀3

Logarithm is a mathematical tool used to make high value calculations simple.

It is the exponent to the power of which a number must be raised to give a certain result.

Some of the important formulas in logarithm are:

logₐb where a is considered as base of the logarithm and b is the argument

is given as nlogab

when base and the argument is same , log is given as 1

logₐbc where a is the base is given as logₐb + logₐc

logₐbc where a is the base is given as logₐb-logₐc

Now it is given to us to find the logarithmic form of 8/27=(2/3)^3

Let us consider the base of the logarithm to be 10

thus log₁₀8/27=log₁₀(2/3)^3

log₁₀8/27=log₁₀(2/3)^3

We know that logₐb can be written as log₂b/log₂a

Hence

log₁₀8/27= 3(log2/3)

log₁₀8/27=3(log2-log3)

log₁₀8/27= 3log2-3log3

Hence the expression becomes 3log2-3log3

Joy was charged the labor of 11 hours .

Joy was charged a total of $1215 from the landscaper for listed parts and labor.

He was charged $445 for listed parts

He was charged the rest for labor

The hourly rate for labor is $ 70

Let the number of hours worked by labor be x

so, we can form a linear equation here as 445 + 70x = 1215

Now we have to solve this linear equation

445 + 70x = 1215

70x= 1215 - 445

70x = 770

x = 770/ 70

x = 11

Therefore, 11 hours of labor were needed to complete the job.

The correct question is Joy recently hired a landscaper to do some necessary work. On the final bill, Joy was charged a total $1215.  $445 was listed for parts and the rest for labor. If the hourly rate for labor was $70, how many hours of labor were needed to complete the job?

From the given distribution, we have that:

a) The distribution is skewed to the left.

b) The median is of 74.

c) The mean will be smaller than the median.

Since life expectancies are clustered at the high end, the outliers are small life expectancies, meaning that the mean will be smaller than the median and the distribution is skewed to the left.

The median of a data-set is the 50th percentile, the value that separates the bottom 50% of the data-set from the upper 50%.

In this problem, we have that about half of all the countries having a life expectancy between about 74 and the maximum of 84.7, meaning that 74 is the median.

The approximate height of the gymnast above the ground level after 1.2 seconds is 8.2 feet

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The complete question is added at the end of the solution

The equation of the height function is given as

h(t) = -5t² + 10t+4

After 1,2 seconds, we have:

t = 1.2

Substitute t = 1.2 in the equation h(t) = -5t² + 10t+4

So, we have

h(t) = -5 x 1.2² + 10 x 1.2 + 4

Evaluate the exponent

So, we have

h(t) = -5 x 1.44 + 10 x 1.2 + 4

Evaluate the products

So, we have

h(t) = -7.2 + 12 + 4

Evaluate the sum

So, we have

h(t) = -7.2 + 16

Evaluate the difference

So, we have

h(t) = 8.2

Hence, the approximate height of the gymnast above the ground level after 1.2 seconds is 8.2 feet

This means that the required approximate height of the gymnast above the ground level after 1.2 seconds is 8.2 feet

Let the number be x
Subtract 8 from x ==>   x - 8

Multiply by -3 ==>         -3(x - 8) = -3(x) -3(-8) = -3x - 24

This equals 21

So
-3x + 24 = 21

Subtract 24 from both sides:

Using division and the graph, the zeroes of the function are given as follows:

The function in this problem is defined as follows:

f(x) = -3x³ -4x² + x + 2.

From the graph, we have that x = -1 is a zero of the function, meaning that it can be written as follows:

-3x³ -4x² + x + 2 = (x + 1)(ax² + bx + c).

The other zeros will be the zeros of ax² + bx + c. To find the coefficients, we use a system of equations, hence:

(x + 1)(ax² + bx + c) = -3x³ -4x² + x + 2

ax³ + (a + b)x² + (c + b)x + c = 2.

Hence the coefficients are given by:

Thus the quadratic equation that we have to solve is:

The total percentage decrease in the number of students on the honor roll is 16.67%.

Percentage is a measure of frequency that is used to express a number as a fraction of an amount out of 100. The sign used to denote percentage is %. In order to convert a number to percentage, multiply the number by 100.

The first step is to determine the number of boys on the honor roll this year.

Number of  boys on the honor roll this year : (1 - percentage decrease) x number of boys last year

(1 - 0.12) x 150

0.88 x 150 = 132

The second step is to determine the number of girls on the honor roll this year.

Number of girls on the honor roll this year : (1 - percentage decrease) x number of girls last year

(1 -0.25) x 84

0.75 x 84 = 63

Total number of students on the honor roll last year = 150 + 84 = 234

Total number of students on the honor roll this year = 63 + 132 = 195

1.  The probability given as P(Y∩X) is; 2/25

2. The probability given as P(Y) * P(X) is; 4/15

We are given the following probabilities;

P(X) = 2/3 , P(Y) = 2/5 , and P(X|Y) = 1/5

1. We want to find P(Y ∩ X).

This means probability of the set intersection of Y and X

Since  P(X) = 2/3 , P(Y) =2/5 , and P(X|Y) =1/5, it means that we have a conditional probability.

Thus;  P(Y∩X) = P(Y) * P(X|Y)

P(Y∩X) = 2/5 × 1/5

P(Y∩X) = 2/25

2. We want to find P(Y) * P(X)

Answer:

q=10, r=8

Step-by-step explanation:

You have to first cancel one of the variables.

8q-15r=-40

4q+2r=56

To do this, multiply the second equation by -2.

8q-15r=-40

-2(4q+2r)=(56)(-2)

Multiply it out.

8q-15r=-40

-8q-4r=-112

Combine like terms.

-19r = -152

Divide by -19 to get the value of r.

r=8

Substitute r back into one of the equations, it does not matter which one. I'll do both.

8q-15(8)=-40

8q-120=-40

8q=80

q=10

4q+2(8)=56

4q+16=56

4q=40

q=10

You should get the same value for q for both.

In the instance where the variables are x and y, which they usually are, you would write your answer as an ordered pair, (x, y).

(10, 8)

Answer:

q=10 and r=8

Step-by-step explanation:

8q-15r=-40 ...........equation(i)

4q+2r=56................eqn(ii)

Now,

Multiplying eqn (ii) by 2 then we get,

8q+4r=112..........eqn(iii)

Here, Subtracting eqn (i) and (iii)

8q-15r=-40

8q+4r=112

(-) (-) (-)

---------------------

-19r=-152

r= -152/-19

r= 8

Again, Putting the value of r in eqn (ii)

4q+2r=56

4q+2×8=56

4q=56-16

q=40/4

q=10

The equation of the line in the graph in slope-intercept form is: y = -5x - 30.

To be able to write the equation of a line in slope-intercept form, y = mx + b, find the value of the slope (m) = rise/run, and the value of the y-intercept (b), which is the value of y where the line intercepts the y-axis.

From the given graph, we have:

Slope (m) = rise/run = -50/10

Slope (m) = rise/run = -5

The y-intercept (b) = -30

Substitute m = -5 and b = -30 into y = mx + b:

y = -5x + (-30)

y = -5x - 30

Thus, the equation of the line in the graph in slope-intercept form is: y = -5x - 30.

Given the initial speed and time elapsed by the car, the negative acceleration that brings the car to a stop at the red light is -5.56m/s².

Newton's first equation of motions states that;

v = u + at

Where v is final velocity, u is initial velocity, a is acceleration and t is time.

Given the data in the question;

First, convert the unit of the initial velocity from kilometer per hour to meter per seconds

Initial velocity = 80 km/h = ( 80 × 5/18 )m/s = 2.2222 m/s

Now, plug these values into the equation above and solve for a.

v = u + at

0 = 22.2222m/s + ( a × 4s )

a × 4s = -22.2222m/s

a = 22.2222m/s ÷ 4

a = -5.56m/s²

Negative sign shows that the car is slowing down.
