√10·√8 is this equal to the √80?
Answer: yes
Step-by-step explanation:
They are both equal to 4/5
how would i answer this?
Answer:
Option (B).
Step-by-step explanation:
Option (a). {(1, 2), (3, 4), (4, 5), (6, 7)}
Since in every ordered pair value of x corresponds a distinct value of y.
The given ordered pairs represent one-to-one function.
Option (b). {(0, 3), (1, 5), (3, 9), (1, 13)}
In the ordered pairs (1, 5) and (1, 13) value of x correspond to the two different values of y.
Therefore, its not a function.
Option (c). {(-2, 2), (-3, 3), (-4, -4), (-5, -5)}
For every value of x there is distinct value of y.
Therefore, given set of ordered pairs represent a one to one function.
Option (d). {(1, 2), (2, 2), (3, 5), (4, 8)}
Ordered pairs represent a function.
Option (B), will be the answer.

What is expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
5x+3x+2y+4y
Now, moving the like terms aside
As, 5x + 3x are one pair
and, 2y+ 4y is second like term pair
So, 5x+3x+2y+4y
= (5x+ 3x) + (2y+ 4y)
= x(5 +3)+ y (2+4)
= x(8)+ y(6)
= 8x+ 6y
= 2(4x+ 3y)
Hence, the simplified the expression is 2(4x+ 3y).

Amanda puts $1800 into an account that does not earn any interest. Every
month after that, she deposits the same amount of money. This sequence
represents her account balance for the first few months:
$1800, $2000, $2200,...
What is the explicit formula for the amount of money in her account at the
beginning of month n?
Answer:
a(n)=1800+(n-1)200
Step-by-step explanation
The usual formual is an=a1+d(n−1)
a1=The first number is the number you would start on
so 1800=a1
n=the number of times you would do it
you would usually put n-1 because the first number is already been put though the formula
d=the amount of change between each number
so 200=d
A(n)= a of n, like f(n) means f of n
so that why it is a(n)=1800+(n-1)200

Answer: 3/4 = 6/8
so u need 60*6, so
c=60*6 ?
c meaning calories
Answer:
How many calories are in 3/4 cup of honey? = 60/ 1/8*3/4
How many cups of honey will the baker use for 15 cakes? = 3/4*15
How many cakes could the baker make if he has 78 cup of honey? = 7/8 divided by 3/4.

Suppose you observe the number of passengers arriving at a metro station on a shuttle bus that holds up to 8 passengers. Describe the sample space.
Answer:
Sample space can be describes as:
S = {0,1,2,3,4,5,6,7,8}
Step-by-step explanation:
Usually used in probability questions, a sample space is defined as a set of collection of all possible outcomes. It is the list of all possible results.
Sample spaces are usually written using set notation, where each possible outcome is listed only once within curly bracket.
S = {outcome 1, outcome 2, ..........}
As it is given the a bus can hold up to 8 passengers. We need to find the sample space of to number of passengers actually riding the bus.
So the minimum numbers of passengers is 0
The maximum numbers of passengers is 8
So the numbers of passengers lies between 0 and 8.
