Answer:
Pythagorean Theorem: C²= a²+b²
a²+b²=c²
C is the longest line of a right angled triangle and a and b are the other two. If you have "a" and "c", but need to find b. You need to sqaure a and then subtract that from c². Then you have b
An Exponent is any example of ². When a small number is above another number. You multiple the "original" number x amount of time. Ex. 3³ 3*3*3
Bedmas is another way of saying "order of operation". Its the order that you calculate functions. It is calculated in this order: Brackets, Exponents, Division/Multiplication, Addition/Subtraction.
I attached an example of Mean, Median, Mode, and Range.
Area: Area is the total space that a 2D object covers. And to calculate it we have to multiply the length of two sides that share a corner. For example, if we have a rectangle that the length of one side is equal to 3cm and the second side is equal to 5cm. Then we multiply them together to get the area. 3*5=15
Perimeter: The perimeter is the "outline" of a 2D shape. To calculate the perimeter we have to add all the sides together.
if the figure is a rectangle the answer is 473
Answer:
12 boys, 36 girls
Step-by-step explanation:
We can use systems of equations to solve this using substitution.
Let b = # of boys in the class
Let g = # of girls in the class
b + g = 48
g=3b
b+(3b)=48
4b=48
b=12
12*3=36
Check:
36+12=48
Answer: if I’m reading this right the answer should be6 days
Step-by-step explanation: do 12x6=72 then add that to the current 34 shells she has, after this then she will have 108 shells, the amount she is looking for.
