Anyone help me please,find the area of each figure.​
Morgarella [4.7K]

Hey there! :)

Answer:

170 cm².

Step-by-step explanation:

This is an example of a composite figure, so find the areas of each shape separately:

Begin by finding the area of the smaller square. A = s²

A = 7² = 49 cm².

Find the area of the larger square:

A = 11² = 121 cm².

Add up the two areas:

49 + 121 = 170 cm².

The timekeeper for a particular mile race uses a stopwatch to determine the finishing times of the racers. He then calculates th
insens350 [35]

Answer:

300 seconds = 5 minutes

Step-by-step explanation:

At first convert the time in minutes which is

5.75 * 60 = 345 seconds

No as the average is 345 seconds at starts from 45 so we subtract that time from 45 seconds

345-45 = 300 seconds (Mean)

So 300 seconds = 300/60 = 5 minutes

So the Accurate mean is 5 minutes

What number divided by 2 3 4 5 6 has a remainder of 1 but when divided by 7 has no remainder?
Afina-wow [57]
301

We could start by finding the lowest common multiple of 2, 3, 4, 5, and 6, which is 60. Then, we can consider the next few multiples: 120, 180, 240, 300...

However, because we need a remainder of 1 when our number is divided by each of these numbers (2,3,4,5,6), we want to go one above each of these multiples. So we're talking about 61, 121, 181, 241, 301... Those are the numbers that will satisfy the "remainder of 1" part of the question.

Now, we need to find out which one satisfies the other part of the question, which just requires dividing each of these numbers by 7 to see which is divisible by 7 (in other words, which one gives us a remainder of zero when we divide by 7). 

301 does it. 301/7 = 43. So 301 is a multiple of 7 and therefore will yield no remainder when divided by 7.

Hope this all makes sense.
