Answer:
perimeter of square=4×side
perimeter of square =4×13cm
perimeter of square = 52cm
area of square = side²
area of square = (13cm)²
area of square = 169cm²
Answer:
52 cm / 169 cm²
Step-by-step explanation:
To find the perimeter, we can add together the lengths of all the sides. Since the height and width of the square are the same length, we can tell all four sides are equal.
13 + 13 + 13 + 13 = 52
The perimeter is 52 cm.
The area is the length times the width of the shape, so we have to multiply 13 by 13.
13 · 13 = 169
The area is 169 cm².
The answer is the third option, 52 cm / 169 cm².
Good luck :)

Answer:
Triangle 2
Step-by-step explanation:
5, 12, 13
Use the Pythagorean Theorem
a^2 + b^2 = c^2
a = 5
b = 12
c = 13
25 + 144 = 169
a and b are side lengths
c is the hypotenuse
The theorem states that the square of the side lengths of a right triangle added together equals the square of the hypotenuse
Answer:
B is the right triangle because the sum of the square of each of the two shortest sides will equal the square of the longest side.
Step-by-step explanation:
Pythagorean Theorem says if a triangle is a right triangle with side lengths a, b, and c, then a^2 + b^2 = c^2 where c is the length of the longest side.
So, A. 16^2= 7^2 + 12^2 256 does not = 193 NOT a right triangle
B. 13^2= 5^2 + 12^2 169 = 169 Yes this is a right triangle
C. 9^2= 4^2 + 5^2 81 does not = 41 NOT a right triangle
D. 19^2= 8^2 + 15^2 361 does not = 289 NOT a right triangle

Please answer ASAP! If 0 is an angle in quadrant II, what is the value of sin(0)
Answers
Answer:
Option A
Step-by-step explanation:
It's given that cosθ = [tex]-\frac{2\sqrt{5} }{5}[/tex]
Since, cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex] = [tex]-\frac{2\sqrt{5} }{5}[/tex]
= [tex]\frac{2}{\sqrt{5}}[/tex]
By applying Pythagoras theorem in the right triangle,
(Hypotenuse)² = (Opposite side)² + (Adjacent side)²
(√5)² = (Opposite side)² + (2)²
5 = (Opposite side)² + 4
Opposite side = √(5 - 4)
= 1
Since, sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{1}{\sqrt{5}}[/tex]
Since, sine is positive in IInd quadrant,
sinθ = [tex]\frac{1}{\sqrt{5}}[/tex]
Therefore, option A will be the answer.

If there are already 3 fish in the aquarium. Then the number of fish in the aquarium should be less than 2.
What is inequality?Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.
There must be fewer than 5 fish in the small aquarium. There are already 3 fish in the aquarium. Then the inequality equation will be
Let the number of fish in the aquarium be x. Then the inequality equation will be
x < 5
But there are already 3 fish in the aquarium, then we have
x - 3 < 2
Then the number of fish in the aquarium should be less than 2.

ill give brainlist thingy lol

Step-by-step explanation:
If you are talking about an inverse function f-1(x) of the function f(x), you must remember that, by definition,
f(f-1(x)) = x
So given f(x) = x/4 if I apply an arbitrary K which is equal to f-1(x), then
f(K) = x
K/4 = x
K = 4x
But I want to recover f-1(x), so replace it back.
f-1(x) = 4x

Answer:
1. (a) a+b=86
2. (c) 5.99a+9.99b≤600
Step-by-step explanation:
1.
a = amount of 16gb memory sticks
b = amount of 21gb memory sticks
Gary is buying a memory sticks for each of the 86 teachers. Therefore the total sum of both 16gb and 32gb memory sticks should equal 86:
a+b=86
2.
a = amount of 16gb memory sticks
b = amount of 21gb memory sticks
Each 16gb memory stick cost $5.99, and each 32gb one costs $9.99. Therefore...
5.99a = total cost of 16gb memory sticks
9.99b = total cost of 32gb memory sticks
Gary has to spent an amount less than or equal to $600. Therefore, the total sum of the costs of both 16gb and 32gb memory sticks should be less than or equal to 600:
5.99a+9.99b≤600
Running the last lap of a 4 x 100-meter relay, Bob takes the baton for his team and pursues his opponent already 20 meters ahead of him. If Bob runs at an average speed of 8 meters per second and his opponent only runs 6 meters per second, will Bob overtake him and win the race? If he does not catch him, how close does he get before the opponent crosses the finish line? If he does catch him, how many seconds and how many meters will it take?
Answers
Answer:
v1 t = distance Bob travels
v2 t + 20 = distance opponent travels
v1 t = v2 t + 20
t = 20 / (v1 - v2) = 20 / (8 - 6) = 10 sec
In 10 sec Bob runs 80 m
In 10 sec opponent runs 20 + 60 m = 80 m
Which of the following are accurate descriptions of the distribution below? (LOOK AT IMAGE PLEASE I MARK BRAINLIEST)
Choose all answers that apply:
A: The Distribution has an Outlier
B: The Distribution has a peak at 22 degrees celsius
C: None of the Above
Answers
Answer:
B: The Distribution has a peak at 22 degrees celsius
Step-by-step explanation:
We are given a photo of a point plot, including with several descriptions and are asked to find which accurately describes the picture.
Let's take a look at our options,
A: The Distribution has an Outlier
This would be incorrect, an outlier is a point on any graph that doesn't really fit in well with all the other points, say there is a straight line with a bunch of dots surrounding it, then there is one dot that is far away from the rest, that is an outlier. Looking at the point plot, we see that all the dots fit in well together and no dots are really separated, therefore making this incorrect.
B: The Distribution has a peak at 22 degrees celsius
This would be correct, when referring to peak, the peak is supposed to represent the highest point or value a certain number/amount has. If we look at the point plot, we can see that there are the most dots at 22 than any other temperature. Therefore making it the peak, and making B correct.
C: None of the Above
This is obviously incorrect, B is a correct answer.
