Answer:
A=246cm
Step-by-step explanation:
L= 9
W= 3
H= 8
2·(3·9+8·9+8·3)= 245
Formula= A=2(wl+hl+hw)
Answer:
Third choice, 3/4
Step-by-step explanation:
Add all the cubes together, 12 + 5 + 3 = 20
There's a 12/20, which is 3/5, chance you'll get a green cube
5/20, which is 1/4, chance you'll get a blue cube
And there's a 3/20 chance you'll get a yellow cube
The probability of not getting a blue cube is 12/20 + 3/20 = 15/20 = 3/4
<h2>
Hello!</h2>
The answer is:
The correct option is the third option;
<h2>
Why?</h2>
To find which of the options expresses the intersection of the three days as an inequality in terms of temperature "t" we need to find an inequality which starts at the lowest temperature (greater or equal) and finish at the highest temperature (less or equal).
So, we have that the lowest temperature is -23°F and the highest temperature is 50°F, there are two options for that range, but we need to consider that the temperature will range from -23° to 50°, so, the correct option is the third option;
We can see that the inequality express that the temperature will range from -23°F being greater or equal than that, to 50°F being less or equal than that.
Have a nice day!
Answer:
Step-by-step explanation:
Here we are given with two coordinates and asked to determine the distance between them.
Here we are going to use the distance formula, which is given as under
Where
Replacing these values in the distance formula
Hence the Distance is 7.071 units
Answer:
x = 52.2 degrees
Step-by-step explanation:
In this question, we are to
calculate the value of the angle x
Now the first thing to identify is that what we have is a right angled triangle as one of the angles is 90 degrees
This means that we can employ the use of trigonometric identities to calculate whatever we want to calculate.
The question now is which trigonometric identity is the correct one to use
To answer this, we need to be sure of the sides we were given. Looking at the diagram we have one side facing the 90 degrees angle and the other side facing the angle x itself.
The one facing the angle given is the opposite while the one facing the angle 90 is the hypotenuse
So the trigonometric identity to use is the one that links the opposite and the hypotenuse
This is the sine
mathematically;
sine of an angle = length of opposite/length of hypotenuse
In this case
sine x = 6.4/8.1
sine x = 0.7901
Thus;
x = arc sin 0.7901
x = 52.2 degrees
