Answer 1

Step-by-step explanation:

so, you did not pay attention to even the simplest of facts in the class ?

the radius is always half of the diameter, or (in other words), the diameter is always twice the radius.

that is really all there is to this.

please tell me you need actual help to divide something by 2 ?

you need me to be your calculator ? posting the questing and then typing the results in from here is more effort than just to use your own calculator.

1. 12.6/2 = 6.3 cm

2. 31.08/2 = 15.54 ft

3. (10 7/11)/2 = (110/11 + 7/11)/2 = 117/11 / 2 =

= 117/22 = 5 7/22 cm

(you noticed something ?)

4. sqrt(54)/2 = sqrt (54/4) = sqrt(27/2) = sqrt(13.5) =

= 3.674234614... m

5. 10.125/2 = (10 1/8)/2 = 5 1/16 = 5.0625 in

Answers

The perimeter of the picnic area is 107 yards

Complete Question:

A triangular picnic area has the side lengths of 45, 31 and 31 yards; To the nearest yard, what amount of fencing is needed to surround the perimeter of the picnic area? 95 yards 107 yards 160 yards 190 yards

How to determine the perimeter?

From the complete question, we have:

Shape: Triangle

Side lengths = 45 yards, 31 yards, 31 yards

The perimeter is the sum of the side lengths.

So, we have:

Perimeter = 45 + 31 + 31

Evaluate

Perimeter = 107

Hence, the perimeter of the picnic area is 107 yards

Step-by-step explanation:

Setting up the equation:

eight LESS (so minus sign before the 8) THAN (so 8 is being subtracted from the -9x) negative (-) nine TIMES (multiplication) a number, (variable) x.

We want to get the variable y alone, so this can be written as y = -9x - 8

No incorrect. If you said 1m = 100 your answer would be correct. The answer would be 4 x 100 to get 400 cm. Pls give brainly I really want a new rank before my b day

Answer:

This is incorrect because 1 meter is 100 centimeters. But then when you keep going and when you get to 4 meters, you would get 400.

For example:

[tex]\qquad \sf \dashrightarrow \: 5z - 5z+ 20 + 10[/tex]

[tex]\qquad \sf \dashrightarrow \: 30[/tex]

So, the equivalent expression is 30

Answer:

Step-by-step explanation:

Let us divide the whole expression by 5. Then we must multiply the whole expression by 5 to obtain the same value as before.

Thus, we get the following expression:

[tex]\implies\huge\text{[}\dfrac{5(z+4)+5(2-z)}{5}\huge\text{]} \times 5[/tex]

[tex]\implies\huge\text{[}\dfrac{(z+4)+(2-z)}{1}\huge\text{]} \times 5[/tex]

Now, open the inner-most parentheses as the expression inside the inner-most parentheses, cannot be simplified further.

[tex]\implies\huge\text{[}\dfrac{z+4+2-z}{1}\huge\text{]} \times 5[/tex]

It should be noted that any number being subtracted from the same number is equivalent to 0. Therefore, we get the following expression:

[tex]\implies\huge\text{[}\dfrac{4+2}{1}\huge\text{]} \times 5[/tex]

Simplify the expression inside the long brackets.

[tex]\implies\huge\text{[}\dfrac{6}{1}\huge\text{]} \times 5[/tex]

Now, we can open the long brackets and simplify the product of 6/1 and 5.

[tex]\implies\huge\text{[}\dfrac{6}{1}\huge\text{]} \times 5 = \dfrac{6 \times 5}{1} = \dfrac{30}{1} = 30[/tex]

Therefore, the simplified expression is 30.

What is the slope of a line that goes through (2,-2) and (5,6)?

Answers

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

So input the numbers:

m = (6 - -2) / (5 - 2)

m = (8) / (3)

Then divide!
8/3 = 2 2/3

the slope of the line is 2 and 2/3

Diego wondered how far sixth-grade students could throw a ball. he decided to collect data to find out. he asked 10 friends to throw a ball as far as they could and measured the distance from the starting line to where the ball landed. the table shows the distances he recorded in feet.
40 76 40 63 47 57 49 55 50 53
find the median and iqr of the data set.
on a later day, he asked the same group of 10 friends to throw a ball again and collected another set of data. the median of the second data set is 49 feet, and the iqr is 6 feet.
did the 10 friends, as a group, perform better (or throw farther) in the second round compared to the first round? explain how you know.
were the distances in the second data set more variable or less variable compared to those in the first round? explain how you know.

Answers

The median of the number recorded in the question is 51.5 feet. This is obtained by dividing the sum of two numbers that occur centrally in half.

What is median?

The central value in a list ordered from smallest to largest is the median of a set of values.

What is the Inter-quartile Range (IQR) of an observation?

The formula for the Inter-quartile range is given as:

IQR = Q₃- Q₁ (that is Median of the Upper Half Less the Median of the lower half)

Step 1 - First, let's arrange the numbers sequentially

→ 40, 40, 47, 49, 50, 53, 55, 57, 63, 76

Step 2 - Determine the upper and lower halves and their median

If the Lower half is 40, 40, 47, 49, 50, then it's median is 47

If the Upper half is 53, 55, 57, 63, 76, then its median is 57.

Hence:

IQR = 57 - 47

= 10 feet.

Given that the median of the second data set is 49 feet, and the IQR is 6 feet. Did the 10 friends, as a group, perform better (or throw farther) in the second?

No, the friends didn't perform better in the second round because the was a significant drop in the median and the IQR. The median dropped from 51.5 to 47 and the IQR from 10 to 6.

Were the distances in the second data set more variable or less variable compared to those in the first round?

It can be concluded that the distance in the second set of data is less variable when juxtaposed with those form the first set.
