AREA- 488 cm squared...

Area of the Rectangle is 374 cm squared.

Area of rectangle: l x w

17 x 22 = 374

Area of the Triangle is 114 cm squared

Since the full side is 22, you will subtract 10 from the other side to find the height of the triangle.

22 - 10 = 12

Area of Triangle: b*h*1/2

12 * 19 = 228

228 * 1/2 = 114

Add the areas, and you get 488 cm squared.

Answer:

Area for rectangle = B*H

Area for triangle = B*H/2

total area = area of triangle + area of rectangle

A of rectangle = 17 * 22 = 374 cm²

Triangle height is not giving so we take 22-10 = 12 cm for the height so

A of triangle = 12*19/2 = 114 cm²

total A = 114 + 374 = 488 cm²

The farmer had 28 cows. He wanted to bring them into the milking shed in groups of 7. How many groups of cows did the farmer bri

Ostrovityanka [42]

Answer:

(C) Subtract 7 from 28. Keep subtracting 7 from answer until he gets to 0. Then count the number of times 7 was subtracted.

This method is another suitable solution to problem

Step-by-step explanation:

Total number of cows the farmer has = 28 cows

Number of cows in 1 shed = 7

The number of sheds used to keep 28 cows is 28 ÷ 7 = 4 sheds

⇒4 sheds are needed to keep 28 cows.

Now choosing an alternate method:

1) Add 28 and 7 = 28 + 7 = 35 sheds

But 35 sheds ≠ 4 sheds

Hence, NOT AN APPROPRIATE METHOD.

2)Add 7 to 28. Keep adding 7 to the answer for a total of seven times.

28 + 7 .... 7 times = 28 + 7 + 7 + 7 + 7 /+ 7 + 7 + 7 = 77 ≠ 4 sheds

NOT AN APPROPRIATE METHOD.

3)Subtract 7 from 28. Keep subtracting 7 from answer until he gets to 0.

28 - 7 = 21

21 - 7 = 14

14 -7 = 7 and 7 - 7 - 0

Hence, in 4 times the answer is 0

So, the number of sheds required is 4

AN APPROPRIATE METHOD.

4) Multiply 28 by 7.

28 x 7 = 196, 196 ≠ 4 sheds

NOT A APPROPRIATE METHOD.

Hence, the ONLY alternate method to count the totals sheds required is

Subtract 7 from 28. Keep subtracting 7 from the answer until he gets to 0.

Find the measure of GE¯¯¯¯¯¯¯¯. A. 14 B. 20 C. 15 D. 16

julsineya [31]

Answer:

D. 16

Step-by-step explanation:

$GH^2 = GF \times GE$

$12^2 = 9 \times (9+x - 2)$

$144= 9 \times (7+x)$

$\frac{144}{9}= (7+x)$

$16= 7+x$

$16-7=x$

$9=x$

GE = 9 + x - 2 = 9 + 9 - 2 = 18 - 2

GE = 16

MaRussiya [10]

Answer:

The standard deviation of the distribution of sample means for samples of size 60 is of 1.2264.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
