Express 8 1/5% as a mixed number or a fraction
Alexxandr [17]

Answer:

41/5

Step-by-step explanation:

First we change the 8 and 1/5% to 8.2%

Write the fraction down as a number over one = 8.2/1

Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

8.2/1 = (8.2 × 10)

(1 × 10) = 82/10

Reduce the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD (82,10) = 2. So, (82÷2)/(10÷2) = 41/5 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 82/10 is also equal to 81/5 when expressed as a mixed number.

The math department sponsors a Math Family Fun Night each year. In the second year, there were 54 people present. In the fourth
Tamiku [17]

Answer:

y = 23x  + 8

Step-by-step explanation:

Assuming the situation can be modelled using a linear equation, then the line must pass through the point (2,54) and (4,100).

To find the equation of this line, we determine the slope using:

m =  \frac{y_2-y_1}{x_2-x_1}

Substitute the coordinates of the points:

m =  \frac{100 - 54}{4 - 2}  =  \frac{46}{2}  = 23

We use the following formula to find the equation of this line.

y=m(x-x_1)+y_1

We substitute the first point a d slope to get:

y = 23(x - 2) + 54

Expand the parenthesis to get:

y = 23x - 46+ 54

This simplifies to

y = 23x  + 8

This is the slope-intercept from.

State whether the equation represents exponential growth, exponential decay, or neither.
Mila [183]

Answer:

Neither

Step-by-step explanation:

This questions only states

y = 11.1.07\%

This is not a fucntion because there is no variable.

This is not a valid statement, because 11.1.07% is non-sensical.
