34. The sum of the lengths of the two bases of a trapezoid
Oduvanchick [21]

Answer:

h=6

Step-by-step explanation:

the formula for a trapezoid’s area is to multiply the bases (a and b) by the height of the trapezoid, then divide it all by 2.

so typed out, that would look like:

((a+b) h) / 2

and in the case of this problem:

((22) h) / 2 = 66

so just go ahead and solve it algebraically from there and you’re good!

If the student has already read 2525 of the pages, how long will it take them to read the rest of the book? _____ minutes Your a
Alja [10]

The number of pages the student can read in a minute is an illustration of rates.

The time left to complete the whole book is 90 minutes

From the complete question, the student's rate is:

\mathbf{Rate = 50\ pages/hr}

The number of pages is:

\mathbf{Total = 100\ pages}

First, we calculate the time to read the whole book

\mathbf{Total\ Time = \frac{Total\ pages}{Rate}}

\mathbf{Total\ Time = \frac{100\ pages}{50\ pages/ hr}}

\mathbf{Total\ Time = 2\ hours}

The number of the student has read is:

\mathbf{Pages = 25}

Next, we calculate the time spent on the 25 pages

\mathbf{Time\ Spent = \frac{Pages}{Rate}}

\mathbf{Time\ Spent = \frac{25\ pages}{50\ pages/hr}}

\mathbf{Time\ Spent = 0.5\ hr}

Convert to minutes

\mathbf{Time\ Spent = 30\ minutes}

So, the time left is:

\mathbf{Time\ Left = Total\ Time - Time\ Spent}

This gives

\mathbf{Time\ Left = 2\ hours- 30\ minutes}

\mathbf{Time\ Left = 1\ hour, 30\ minutes}

Convert to minutes

\mathbf{Time\ Left = 90\ minutes}

Hence, the time left is 90 minutes

For each month of a given year except December, a worker earned the same monthly salary and donated one-tenth of that salary to
kiruha [24]

Answer:

D) 11/3

Step-by-step explanation:

Let x represent monthly salary.

We have been given that for each month of a given year except December, a worker earned the same monthly salary and donated one-tenth of that salary to charity.        

Salary earned in 11 months would be 11x.

Money donated in 11 months would be \frac{11x}{10}.

Further we are told that in December, the worker earned N times his usual monthly salary and donated one-fifth of his earnings to charity.

Salary for December would be Nx.

Money donated in December would be \frac{Nx}{5}.  

The worker's charitable contributions totaled one-eighth of his earnings for the entire year that is \frac{1}{8}\cdot (11x+Nx).

\frac{11x}{10}+\frac{Nx}{5}=\frac{1}{8}\cdot (11x+Nx)

Dividing whole equation by x, we will get:

\frac{11x}{10x}+\frac{Nx}{5x}=\frac{1}{8x}\cdot x(11+N)                

\frac{11}{10}+\frac{N}{5}=\frac{1}{8}\cdot (11+N)

\frac{11}{10}+\frac{N}{5}=\frac{11}{8}+\frac{N}{8}

Combine like terms:

\frac{N}{5}-\frac{N}{8}=\frac{11}{8}-\frac{11}{10}

\frac{N}{5}*40-\frac{N}{8}*40=\frac{11}{8}*40-\frac{11}{10}*40

8N-5N=11*5-11*4

3N=55-44

3N=11

\frac{3N}{3}=\frac{11}{3}\\\\N=\frac{11}{3}

Therefore, the value of N is 11/3 and option D is the correct choice.
