The perimeter of a rectangle is 34 units. Its width is 6.5 units. Write an equation to determine the length of the rectangle.

julsineya [31]

Answer:

The length for a rectangle with a perimeter of 34 units and a width of 6.5 units would be 10.5 units.

Step-by-step explanation:

To find the length, you can use the equation [34 - (6.5 x 2) ÷ 2 = the length]. So, 6.5 x 2 = 13, then 34 - 13 = 21, finally, 21 ÷ 2 = 10.5 . So the length of the rectangle is 10.5 . To double check, (6.5 x 2) + (10.5 x 2) (=) 34. So this answer is correct.

Six football players, all defensive linemen, decide that they'll gain an average of 10 pounds over the summer. At the start of t

noname [10]

Answer: b. 14 pounds

Step-by-step explanation:

Formula to calculate average :

$\text{Average}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}$

Let x denotes the number of pounds the last person have to gain so that the group can attain its goal.

Required average = 10 pounds

Observations = 9, 13, 11, 6, 7 and x (pounds)

Number of observations= 6

Sum of all observations = 9+13+ 11+ 6+7+x=46+x

According to the question , we have

$10=\dfrac{46+x}{6}\\\\ 46+x=10\times6\\\\ 46+x=60\\\\ x=60-46=14$

i..e the last person has to gain 14 pounds so that the group can attain its goal.

Hence, the correct answer is b. 14 pounds .

A= 8
Because
25 : 5
40 : a?
Cross multiplication
200 : 25a
Divide both sides by 25
You will get 8!
