The perimeter of a rectangular garden is 338 m.If the width of the garden is 74 m, what is its length?

Answers

Answer:

l=95

Step-by-step explanation:

Perimeter is all the sides add up. So the equation if you know two of the sides, it should be: 338=(2*74)+(2*l)

Answer:

Step-by-step explanation:

the perimeter is 2w plus 2l

so 338 = 74(2)+2l

338 = 148+2l

190=2l

l=95

your length would be 95 m

A right pyramid has a regular hexagon as a base. The slant height is 20, and the perimeter of its base is 10. What is the lateral surface area of the pyramid

Answers

Answer:

100 unit^2

Step-by-step explanation:

lateral surface area of right pyramid = .5*p*s

p = perimeter

s = slant ht

LS = 100 unit^2

Which fraction is not equivalent to 16/24 A. 2/3 B. 5/8 C. 32/48 D. 4/6

Answers

b) 5/8
because:
2/3 x 8 = 16/24
32/48 divided by 2 = 16/24
4/6 x 4 = 16/24
so b) 5/8 it is
5/8 because 
If you divide 16 by 8 then you get 2 and if you divide 24 by 8 you get 3 this equals=2/3
32/48- If you multiply 16 by 2 you get 32, if you multiply 24 by 2 you get 48 which gives you an answer to 32/48
4/6- If you divide 16 by 4 you get an answer of 4, if you divide 24 by 4 you get an answer of 6, which gives you an answer of 4/6

Maggie and her friends are each able to recruit a certain number of people each year to sample a product. The number of people per year is represented by the function f(t) = 3(2)t. What does the t represent? How many people were recruited in 6 years?.

Answers

If the function is:
f ( x ) = 3 * 2^(t) 
t represents time ( in years ).
In 6 years :
f ( 6 ) = 3*2 ^(6) = 3* 64 = 192
Answer: 
B ) t represents the number of year; 192 people were recruited in 6 years.

Answer:

B. t represents the number of years ; 192 people were recruited in 6 years

Answer:

.42n = p

Step-by-step explanation:

We can write ratios to solve

2.52 / 6 = p/n

.42 = p/n

Multiply each side by n

.42n = p

Answer:

A is the answer

Step-by-step explanation:

You have to divide $2.42 by 6.

2.52/6=0.42

The unit rate would be

p=0.42n

So for every orange it will cost $0.42

Hope this helps

Notes: 
The notation ">=" without quotes means "greater than or equal to"
The upper case "U" means "set union"
Instead of using the intersection symbol, I will use a lower case 'n'

-------------------------------

Problem 1

A = {x | x < 1} which is the set of x values smaller than 1
B = {x | x >= 5} is the set of x values that are equal to 5 or larger
A U B = set of values that are from set A OR they are from set B (or both)
A U B = {x | x < 1 or x >= 5}
we simply connect the two inequalities mentioned with an "or" 

note: how there is no overlap between the two regions. The "U" means "set union" which is like a sort of glue to tie the two sets together with an "or". 

Answer: {x| x < 1 or x >= 5}
-------------------------------
Problem 2

A = {x | x < 1}
C = {x | x = 5} which is the set of one value only: 5 (x cannot equal any other value)
A U C = {x| x < 1 or x = 5}

So if a number is in set A U C, then this number is either less than 1, OR it is equal to 5

Answer: {x|x < 1 or x = 5}
-------------------------------
Problem 3

B U C = {x | x >= 5} because set C already has the "or equal to" part in there. 

Set C is a subset of set B. If an item is in set C, then it is also in set B.

Answer: {x| x >= 5}
-------------------------------
Problem 4

Again recall that I'm using an 'n' to indicate "set intersection" instead of the upside down "U" symbol

A n B is the set of items that are in BOTH sets A and B at the same time. From problem 1, I mentioned there's a gap. There is no x value that is both less than 1 AND greater than or equal to 5. So this means that

A n B = empty set

which we use the "O" with a slash through it. This is a special symbol to indicate "empty set"

Another way to write "empty set" is to use curly braces with nothing inside like so { } 

Answer: The "O" with a slash through it
-------------------------------
Problem 5

B n C is the same as {x| x = 5}

Why? Because if an item is in B n C, then it has to be in BOTH set B and set C at the same time. The only way this happens is if x = 5. If x is any other value, then it won't be in set C

Answer: {x| x = 5}
