Answer:
n = -7,6
Step-by-step explanation:
n(n+1)+3=45
distributive property: a(b+c) = ab+ac
n²+n+3 = 45
n²+n -42 = 0
factor now
(n+7)(n-6) = 0
n = -7,6
I swear if it’s wrong I’m sorry ok but it’s 3 for me
Answer:
which would be 1 third times 3.14 times 6 squared times 33
Step-by-step explanation:
okay so your dealing with a cone and a hemisphere. so what you would do is the cone equation is 
multiplied by 
multiplied by the radius squared times the height so what u would o is plug in the things you know .
Answer:
Step-by-step explanation:
There are 2 ways to proceed further.
Option A is with using the random number table.
- Let us assume that each gravestone has a unique number between 1 and 55914.
- Choose a row at random from the table.
- Take the first number consisting of 5 digits, if the number corresponds with a number between 1 and 55914, then select the corresponding plot, otherwise move on to the next 5 digit-number.
Repeat until 395 gravestones have been selected.
Option B is with using any calculator with capability of generating random integer. Here for example consider any TI series programmable calculator.
- Enter the following command into your calculator:
randInt(1,55914,395)
- The first and second number are the lower and upper limits between which the values have to lie.
- The third number is the number of required selections.
This theorem says that the exterior angle is equal to the sum of its remote interior angles. In other words, 140 = 2x + x + 2. 140 = 3x + 2 and 138 = 3x. Therefore, x = 46. Multiply it by 2 to get angle B is 92 degrees.
