Which triangle’s unknown side length measures 53 sqrt units?

assuming they are right triangles
we know that
c²=a²+b²

case a) 6 and 91sqrt
c=√91
a=6
b=√53
so
a²+b²----> 6²+√53²----> 36+53----> 89
89 is not √91²

case b) 10 and 47sqrt
c=10
a=√53
b=√47
a²+b²----> 53+47----> 100
100 is equal to 10²------> is ok

case c) 34sqrt and 19sqrt
c=√53
a=√34
b=√19
a²+b²----> 34+19----> 53
53 is equal to √53²----> is ok

case d) 20 and 73sqrt
c=20
a=√73
b=√53
a²+b²----> √73²+√53²----> 126
126 is not 20²

the answers are
10 and 47sqrt
34sqrt and 19sqrt

How do i Evaluate this expression?

timofeeve [1]

$\text{Hey there!}$

$\bf{9.83+8.2(7.01)}$

$\text{You could solved this equation by doing PEMDAS}$

$\text{PEMDAS simply means}\downarrow$

$\text{Parentheses }$

$\text{Exponents}$

$\text{Multiplication}$

$\text{Division}$

$\text{Addition}$

$\text{Subtraction}$

$\text{In your equation you have \bf{MULTIPLICATION \& ADDITION}}$

$\text{Now, that we have every information we need.. lets solve the problem}$

$\text{We have to do \underline{MULITPLICATION} first then \underline{ADDITION} last}$

$\text{9.83 + 8.2(7.01)}$

$\text{8.2(7.01)=57.482}$

$\text{9.83 + 57.482 = 67.312}$

$\boxed{\boxed{\text{Thus your answer is most likely: \bf{67.312}}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$

Mrs. Myles gave the same test to both her first and third period class. In first period, the median was 75 and the range was 30.

Dennis_Churaev [7]

Answer:

The range is the difference between the biggest and smaller values of a set. The median is the middle value of a set. So we cannot say were the lowest score was found, comparing the median and ranges, because it could be that some repeated value very low or high is biasing the median, we could do it with the mean perhaps. So the proposal is false.

What is the slope of a horizontal line?

Misha Larkins [42]

Answer:

Slope of a horizontal line. When two points have the same y-value, it means they lie on a horizontal line. The slope of such a line is 0, and you will also find this by using the slope formula.
