It is given in the question that
Ann, Chang, and Kareem sent a total of 89 text messages over their cell phones during the weekend. Ann sent 9 fewer messages than Chang. Kareem sent 3 times as many messages as Ann.
Let number of messages Chang sent be x. And Ann sent 9 fewer than Chang, so Ann sent (x-9) messages. And Kareem sent 3 times as many messages as Ann, so Kareem sent 3(x-9) messages.
And the total messages are 89. That is
![x+x-9+3(x-9)=89](https://tex.z-dn.net/?f=x%2Bx-9%2B3%28x-9%29%3D89)
Combining like terms
![x + x - 9 + 3x-27 =89 \\ 5x -36=89 \\ 5x = 125 \\ x =25](https://tex.z-dn.net/?f=x%20%2B%20x%20-%209%20%2B%203x-27%20%3D89%0A%5C%5C%0A5x%20-36%3D89%0A%5C%5C%0A5x%20%3D%20125%0A%5C%5C%0Ax%20%3D25)
So Chang sent 25 messages, Ann sent
![25-9=16 messages](https://tex.z-dn.net/?f=25-9%3D16%20messages)
And Kareem sent
![3*16 = 48 messages](https://tex.z-dn.net/?f=3%2A16%20%3D%2048%20messages)
Answer:
59.16 units
Step-by-step explanation:
Given that,
The length of rectangle, L = 13
The breadth of the rectangle, B = 6
The perimeter of the shaded region = perimeter of rectangle - 2(perimeter of semicircle)
![P=13\times 6-[2\times \dfrac{2\pi r}{2}]\\\\=78-2\pi r\\\\=78-2\times 3.14\times 3\\\\=59.16](https://tex.z-dn.net/?f=P%3D13%5Ctimes%206-%5B2%5Ctimes%20%5Cdfrac%7B2%5Cpi%20r%7D%7B2%7D%5D%5C%5C%5C%5C%3D78-2%5Cpi%20r%5C%5C%5C%5C%3D78-2%5Ctimes%203.14%5Ctimes%203%5C%5C%5C%5C%3D59.16)
So, the perimeter of the shaded region is 59.16 units.
Meredinth takes 24 minutes to reach her friend house
<em><u>Solution:</u></em>
Given that, Meredith lives 24 blocks from her friends house
She travels one block every minute
<em><u>To find: time taken by Meredith to reach friend house</u></em>
From given,
Number of blocks between Meredith house and her friedn house = 24
She travels one block every minute
Thus she takes 1 minute for 1 block
One block = 1 minute
So, for 24 blocks, we have to multiply by 24
![24\ block = 1 \times 24\ minute\\\\24\ block = 24\ minute](https://tex.z-dn.net/?f=24%5C%20block%20%3D%201%20%5Ctimes%2024%5C%20minute%5C%5C%5C%5C24%5C%20block%20%3D%2024%5C%20minute)
Thus Meredinth takes 24 minutes to reach her friend house
