A. 42.5 centimeters
B. 65 centimeters
C. 9.2 centimeters
D. 35 centimeters

D.

35 centimeters

Answers

$a^(2)+ b^(2) = c^(2)$ that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.'
$25^(2)+ 60^(2)= x^(2)$
625+3600= $x^(2)$
4225= $x^(2)$
Therefore,
$√(4225)$ =x
65=x
The length of the hypotenuse is B.65 centimetres.

How do you write an inequality to model this situation a number exceeds 21

Answers

a number exceeds 21...it is greater then 21
x > 21

x>21
x represents a number. a number exceeds 21. x is greater than 21 therefore x(a number) exceeds 21.

The results of a survey indicate that between 76% and 84% of the season ticket holders are satisfied with their seat locations.What is the survey’s margin of error?

Answers

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The margin of error of the survey will be ±4%.

What is the margin of error?

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.

The results of a survey indicate that between 76% and 84% of the season ticket holders are satisfied with their seat locations. Therefore, the margin of error can be written as,

Margin of Error = (84%-76%)/2 = 8%/2 = ±4%

Hence, the margin of error of the survey will be ±4%.

Answer:

±4

Step-by-step explanation:

The margin of error in a confidence interval is half the range:

(84 - 76) / 2 = 4

So the margin of error is ±4.

The slope is 5/-5. Hope this helps!

The slope of an equation is rise/run. You'd go down 5 and right 5. This would be -5/5 which can be simplified to -1. The slope of this equation is -1.

Delia can buy 3 sweatshirts for a total of $39. How much would it cost if she were to buy 7 sweatshirts?

Answers

Answer:

7 sweatshirts costs $91

Step-by-step explanation:

Well, first we have to find how much each sweatshirt costs alone. The sweatshirts are $13 each. So, if we multiply 13 by 7, you'll get the amount that 7 sweatshirts costs.

I'm 97% sure this is correct

Find the value of x and RT if RS=24 cm

Answers

RS = RT + TS = 24 cm

Let's plug our values into the equation above

24cm = 6x - 4 + 10cm

Combine like terms

24 cm = 6x + 6 cm

Subtract 6 cm from both sides

18 cm = 6x

Divide both sides by 6

3 = x

Plug 3 into the expression for RT

RT = 6(3) - 4 = 18 - 4 = 14 cm

Similarly, we know that TS = 10 cm and RS = 24 cm

24 cm - 10 cm = 14 cm

RT = 14 cm

14 cm = 6x - 4

Add 4 to both sides

18 cm = 6x

Divide both sides by 6

3 = x
