Answers

Answer 1

Answer:

26 cm

Step-by-step explanation:

To find the perimeter with the side lengths, you can use this formula: 2(L+W) because it's the measure of the distance around the rectangle. So,

2(8.5+4.5)

2(13)=26

A group of men decided to do a job in 8 days.
But since 10 men dropped out every day, the job
got completed at the end of the 12th day. How
many men were at the beginning?

Answers

Given :

A group of men decided to do a job in 8 days.

10 men dropped out every day, the job  got completed at the end of the 12th day.

To Find :

How  many men were at the beginning ?

Solution :

Let, total number of men initially are n.

It none of them leave, total work :

W = 8n    ...1)

It is given that 10 men are dropped each day it takes them 12 day to complete the work :

W = ( n ) + ( n - 10 ) + ( n - 20 ) +  ....   + ( n - 110 )

W = 12n - ( 0 + 10 + 20 + ...... + 110 )

W = 12n - 660    ...2)

Since, total work is same in both the cases, so equating both equation, we get :

12n - 660 = 8n

4n = 660

n = 165

Therefore, their are 165 men in the beginning.

Find the perimeter of the rectangle. 11. 13 cm Area = 52 cm2​

Answers

Answer:

1352 cm

Step-by-step explanation:

Length (l) = 13 cm

Width (w) = 52 cm

Perimeter of the rectangle = 2(l + w) units

P = 2(13 + 8)

P = 2 (21)

P = 42

Thus, the perimeter of the rectangle is 42 cm.

Example 2: If a rectangle's length is 2x + 1 and its width is 2x – 1. If its area is 15 cm2, what are the rectangle's dimensions and what is its perimeter?

Solution:

We know that the dimensions of the rectangle in terms of x:

l = 2x + 1

w = 2x – 1

Since the area of a rectangle is given by:

A = l * w

We can substitute the expressions for length and width into the equation for area in order to determine the value of x.

A = l * w

15 = (2x + 1) (2x -1)

15 = 4x2 – 1

16 = 4x2

x = ±2

Note that the value of x must be positive and therefore in our case, the value of x is 2. And now we have:

l = 11 cm

w = 52 cm

Therefore, the dimensions are 5cm and 3cm.

Now, substituting these values in the formula for perimeter, we will get

P = 2l + 2w

P = 2(5)+2(3)

P = 10+6

P = 16 cm

Malik earns an average of 412 points on his daily quizzes. Near the end of the quarter, his average decreases by 34 points.


Write and then evaluate a subtraction expression (in fraction form) to find his current quiz grade average.

Answers

Answer: Required expression= 412-34

Current quiz grade average = 378

Step-by-step explanation:

Given: The average points on daily quizzes = 412

The average decreases by 34 points.  (Near the end of the quarter)

Current quiz average = (Average points on daily quizzes) - (Average decreases)

i.e. Current quiz average =412-34  [ i.e. Required expression= 412-34]

i.e.  Current quiz average =378

Hence, his current quiz grade average = 378

5. A motorist leaves Derby at 10:55 and arrives in Leicester 1 14 hours later. The
distance from Leicester to Derby is 50 miles.
a) At what time did he arrive in Leicester?
b) What was his average speed in mph?

Answers

Answer:

a. 12:10 pm

b. 40 mph

Step-by-step explanation:

Assuming you meant to type 1 ¹/₄ hours later.

a. First convert that to a improper fraction and then a decimal:

= 5/4

= 1.25 hours

1.25 hours in minutes is:

= 1.25 * 60

= 75 minutes

= 1 hour 15 minutes

The motorist left at 10:55.

= 1055 + 1 hour

= 11:55

Add 15 minutes:

= 12:10 pm

b. Speed = Distance / Time

= 50 / 1.25 hours

= 40 miles per hour

Mean - 79

Median- 81

Range- 11

Step-by-step explanation:

Mean aka average = add all the numbers together and divide it by the number of numbers there were to find the mean of something.

in this case  : 81 + 82 + 84+ 75+73+75 + 83 = 553 divided by 7 = 79

Median -  Rearrange the set of numbers from least to greatest or  greatest to least  and find the middle number to find the median

In this case : 73, 75, 75, 81, 82, 83, 84 =  The median is 81

Range - Substract the highest and the lowest number from the set of numbers to find the range.

In this case : 84 - 73 = 11

Martin will ride his bike from his aunts house. He has two different routes he can take. One route goes up and down hill. The other route avoids the hill by going around the edge of the hill. How do you think the routes will differ. What do you think about the relationship of speed and time?

Answers

Answer and explanation:

One route goes up and down the hill while the other goes around the edge of the hill, in other words one route goes through a hill to get to the destination while the alternative route has a tunnel that makes it possible to avoid the hill.

Relationship between distance and time is given by the formula:

Distance = Speed × time

For example to find the distance travelled with a speed of 10km/hr and 4 hours travelled, we simply multiply speed 10km/hr by time travelled 4 hrs = 40km
