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.
Answer:
3
Step-by-step explanation:
Looking at the first three values of the table- when the x increases by 1, the y increases by 3.
Answer: 33.6 min
Step-by-step explanation:
Volume = L*W*H = 9 * 13 * 14 = 1638 in^3
Vol2 = 21 * 25 *35 = 18375 in^3
18375/1638 = 11.2 times bigger, so 3min * 11.2 = 33.6 minutes
Answer:
-3 and -8
Step-by-step explanation:
Let the two numbers be called a and b respectively. We can say that ab=-24, and a+b=-11.
If a+b=-11, a=-11-b.
ab=-24
(-11-b)b=-24
b²+11b+24=0
(b+3)(b+8)=0
b=-3, b=-8
a=-11-b=-11+3=-8
a=-11-b=-11+8=-3
So the numbers are -3 and -8
Simply plug in numbers!! (3x-1)(5)=55
15x-5=55
15x=60
x=4
hope this helps :)
