You may represent this multiple ways.

1. 66/44 = m

2. 44m = 66

In both of these scenarios you have a total and equal parts.

The first one starts with a total and breaks it into equal parts.

The second choice shows 44 groups of a part totaling 66 meters.

Answer:

We put the value of the x in the formula

${4 \times }(6)^{2} - 7 \times 6 + 12$

f(6)=

$4 \times 36 - 7 \times 6 + 12 = 144 - 42 + 12 = 102 + 12 = 114$

Step-by-step explanation:

Than solve equation.

From a group of 11 people, 4 are randomly selected. What is the probability the 4 oldest people in the group were selected

asambeis [7]

Answer:

<h2>4/11</h2>

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

<em>Probability = expected number of outcome/Total number of outcome</em>

If there are group of 11 people, then the total outcome of events will be 11

If we are to select 4 oldest people from the group, then the expected outcome is 4.

Hence, the probability that the 4 oldest people in the group were selected is 4/11.

Find the equation of the line which passes through the point (7,2) and is perpendicular to y=5x-2

MariettaO [177]

Answer:

$\displaystyle y=-\frac{1}{5}x+\frac{17}{5}$

Step-by-step explanation:

<u>Equation of a line</u>

A line can be represented by an equation of the form

$y=mx+b$

Where x is the independent variable, m is the slope of the line, b is the y-intercept and y is the dependent variable.

We need to find the equation of the line passing through the point (7,2) and is perpendicular to the line y=5x-2.

Two lines with slopes m1 and m2 are perpendicular if:

$m_1.m_2=-1$

The given line has a slope m1=5, thus the slope of our required line is:

$\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{5}$

The equation of the line now can be expressed as:

$\displaystyle y=-\frac{1}{5}x+b$

We need to find the value of b, which can be done by using the point (7,2):

$\displaystyle 2=-\frac{1}{5}*7+b$

Operating:

$\displaystyle 2=-\frac{7}{5}+b$

Multiplying by 5:

$10=-7+5b$

Operating:

$10+7=5b$

Solving for b:

$\displaystyle b=\frac{17}{5}$

The equation of the line is:

$\boxed{\displaystyle y=-\frac{1}{5}x+\frac{17}{5}}$

Three is 7 more than one-fifth of a number.

Paha777 [63]

Answer:

3=1/5x+7

Step-by-step explanation:

when it says "Of a number" it means to add a variable, so i added a x. and when it says "more than" it means to add, so 3=1/5x+7 is the answer
