Mathematics

1 answer:

Alik [6]3 years ago

5 0

Answer:

Rs 17 3/4

Step-by-step explanation:

Cost of 6 1/2 m = 115 3/8

Cost of 1 m = x

x = 115 3/8 ÷ 6 1/2
x = (115*8 +3)/8 ÷ 13/2
x = 923/8 × 2/13
x = 923/(4*13)
x = 923/52
x = 17 39/52
x = 17 3/4

Cost of 1 meter is Rs 17 3/4

Find the Area of this figure.

grin007 [14]

Answer:

158 m²

Step-by-step explanation:

I made this into 3 rectangles.

Figure 1:

9•8=72

The 9 is from the 13 m side, but I've taken 4 m off from the overlapping square.

Figure 2:

6•7=42

The 7 is from the 10 m side, but I've taken 4m off from the overlapping square again.

Remaining Area:

If you extend the lines into figures 1 and 2 from the top left corner and bottom right corner vertically, you will get a rectangle that is (11 m) x (4 m). This is not yet accounted for.

11•4=44

Add together: 72 + 42 + 44 = 158

*Note: You could also find the area of the squares a much easier way by subtracting the overlapping part after finding the area of both figures , but this is how I did it*

The number of wolves in a wildlife preserve is estimated to have increased continually by 3% per year. If the population is now

34kurt

For the answer to the question above, Well, first let us put up a functional equation. 
Since this is an exponential function, it'll be: f(t)=54,000*1.03^t 
But we want to know how many wolves there were 10 years ago. 
For that, we simply "turn time around", as in: f(t)=54,00*1.03^-t 
This displays a decreasing number of wolves, as you turn back time. 

Now we simply calculate 54,000*1.03^-10 
which is approximately 40,200?

Three people spend $22.50 on large popcorns and soft drinks. They go back the next week and each pay $8.00 for each ticket, they

kakasveta [241]

Answer:

Cost of each large soft drink is $3.00 and Cost of each Large bucket of popcorn is $4.50.

Step-by-step explanation:

Let the Cost of each large soft drink be x.

Also Let the Cost of each Large bucket of popcorn be y.

Number of people = 3

Money Spend on popcorn and soft drink = $22.50

Hence we can say that;

$3x+3y=22.50 \ \ \ \ equation \ 1$

Next week three people traveled again.

Each ticket was bought = $8.00

Number of tickets bought = 3

Money spend on tickets = $8\times3 = \$24$

Total return trip = $37.50

Also they each get a large soft drink, but they share one large bucket of popcorn

Cost of Soft drink = 3x

Cost of popcorn = y

Now Total return trip is equal to sum of Money spend on tickets and Cost of soft drink and Cost of popcorn.

Hence equation can be framed as;

$24+3x+y=37.50\\3x+y=37.50-24\\3x+y = 13.50 \ \ \ \ eqaution \ 2$

Now Subtracting equation 2 from equation 1 we get;

$(3x+3y)-(3x+y)=22.50-13.50\\\\3x+3y-3x-y=9\\\\2y= 9\\\\y=\frac{9}{2}=\$4.50$

Now substituting the value of y in equation 1 we get;

$3x+3y=22.50\\\\3x+3\times4.50=22.50\\\\3x+13.50=22.50\\\\3x=22.50-13.50\\\\3x= 9\\\\x=\frac{9}{3}=\$3.00$

Hence Cost of each large soft drink is $3.00 and Cost of each Large bucket of popcorn is $4.50.
