Answers

Answer 1
Answer: A triangular pyramid has 4 triangles
3 are sides
1 is th base
they are normally all the same area
if 1 is 30
3*4=120
yah, 120mm squared is answer
Answer 2
Answer: I hope this helps you



3 triangles area+square area


3.30+30


90+30

G(x)=-3x-8

G( )=10

Please help

Answers

Answer:

-6 goes inside ( ) since G(-6)=10.

Step-by-step explanation:

It looks like you are looking for a number such that when you put in the ( ) of G(  ) you get 10 as a result.

So let's say you are trying to solve G(b)=10 for b.

Well G(x)=-3x-8 so G(b)=-3b-8.

I just replaced all the x's with b's to find G(b).

Now we are trying to solve G(b)=10 for b.

G(b)=10

-3b-8=10

Add 8 on both sides:

-3b=10+8

Simplify:

-3b=18

Divide both sides by -3:

  b=18/-3

Simplify:

  b=-6

So G(-6)=10!

Check:

-3(-6)-8

18-8

10

G(-6)=10 is confirmed.

-6 goes inside the G( )=10.

answer g(-6)=−3x−8=10

Match each item in Column A to an answer in Column B. What property is shown by the equation?


Column A
1.–(–33 + 18) = 33 + (–18)
2.–10 + (–15) = –15 + (–10)
3.4 + (29 + 16) = 4 + (16 + 29)
4.–12 + (12 + 27) = (–12 + 12) + 27

Column B
A.commutative property
B.associative property
C.opposite of a sum property

Answers

Its A. associative property because the problem stays the same like so ex- 2+7+5= 2+7+5

Simplify the following:
sqrt(5) - 16 + sqrt(15) - 8

Grouping like terms, sqrt(5) - 16 + sqrt(15) - 8 = sqrt(15) + sqrt(5) + (-16 - 8):
sqrt(15) + sqrt(5) + (-16 - 8)

-16 - 8 = -24:
Answer:  sqrt(15) + sqrt(5) + -24

On Friday, a fruit stand sold a total of 92 apples and oranges. On Saturday, the fruit stand sold four times the number of apples and two times the number of oranges. A total of 284 apples and oranges were sold on Saturday. Which system of equations yields the number of apples, a, and oranges, o, sold on Friday? A) a + o = 92 4a + 2o = 284 B) a + o = 284 4a + 2o = 92 C) a + o = 92 2a + 4o = 284 D) a + o = 284 2a + 4o = 92

Answers

Option A : a+o = 92 , 4a+2o = 284 is the right answer

Step-by-step explanation:

Let o be the number of oranges sold on Friday and

a be the number of apples sold on Friday

So,

A total of 92 was sold on Friday will yield the equation

On Saturday,

4 times the number of apples = 4a

2 times the number of oranges = 2o

So,

Hence,

The system of equations is:

Option A : a+o = 92 , 4a+2o = 284 is the right answer
