Answer:

4  \frac{5}{28}

Step-by-step explanation:

4  \frac{7}{8}  \div 1  \frac{1}{6}

Convert the mixed numbers above to improper fractions

=  \frac{39}{8}  \div  \frac{7}{6}

Rule of basic operation states that when dividing fractions, the division sign changes to multiplication sign thus turn the right hand side of the fraction inversely such that 7/6 becomes 6/7.

=  \frac{39}{8}  \times  \frac{6}{7}

=  \frac{39 \times 6}{8 \times 7}

=  \frac{234}{56}

Converting the answer above to mixed number result to:

= 4  \frac{5}{28}

Finke typing speed increased from 40 words per minute to 45 words per minute. What was the percent increase?
Kaylis [27]
In the given question, it is already disclosed that the typing speed of Finke has increased from 40 words per minute to 45 words per minute. Now we have to find the percentage increase in the speed of typing.
For this purpose we have to find the solution in the method described below.
Number of increase in words typed per minute = 45 -40
                                                                           = 5
Then Percentage increase in the speed of typing by Finke = (5/40) * 100
                                                                                              = (1/8) * 100
                                                                                               = 25/2
                                                                                               = 12.5
So the percentage increase in the typing speed of Finke is 12.5%. I hope this has answered your question and the description used to solve this problem is understandable.

Can one please help me with this question
Nostrana [21]

Answer:

254.34 cm^2

Step-by-step explanation:

Volume of cylinder = \pi r^{2} h

We know that the diameter is 6, which means that the radius is 3 cm.

Now, it also tell us that that the height is triple the radius, this means that we multiply it by 3. Therefore, the height is 9 cm.

Now we know r = 3 cm and h = 9 cm, pi is assumed to 3.14 as well.

Substituting into the formula we will end up with 254.34 cm^2.

Whats the vertex of a parabola?<br> Round to the nearest hundredth.
olya-2409 [2.1K]

Answer:

To get the x-intercept we need the equation of the parabola;

the vertex form of the equation is given by:

y=a(x-h)^2+k

where:

(2,13) is the vertex:

Therefore;

y=a(x-2)^2+13

when x=0, y=5

Therefore the value of a will be:

5=a(0-2)^2+13

5-13=4a

4a=-8

a=-2

therefore the equation of the parabola will be:

y=-2(x-2)^2+13

y=-2x^2+8x+5

the x-intercept will be:

x=2-sqrt(7.5)

or

x=2+sqrt(7.5)

Step-by-step explanation:
