I think the answer should be divisible because you can’t really divide 1 without getting the same # your dividing by.

Answer:

A natural number greater than 1 that has only itself and 1 as factors is called a <u>prime</u> number

Step-by-step explanation:

A prime number is a natural number greater than 1, that has only two factors;- the natural number itself and 1.
Example:
The factors of 13 are {1,13}, therefore 13 is a prime number.
The factors of 2 are {1.2}, therefore 2 is also a prime number.
Composite numbers have two or more factors.
An exponential number is a power of natural numbers. An example is $9=3^2$
The first choice is correct

The graph of a linear relationship is shown. Which equation best represents the relationship between x and y in the graph

Finger [1]

Answer:

B. y = -3/4x + 5/2

Step-by-step explanation:

Take two points from the graph, let's use (-2, 4) and (2, 1):

Find slope:

m = (y₂ - y₁) / (x₂ - x₁)

= (1 - 4) / (2 - (-2))

= -3/4

Find y-intercept using slope above and anyone point:

y = mx + b

(1) = -3/4(2) + b

1 = -3/2 + b

b = 1 + 3/2

b = 5/2

Equation of line using m and b above:

y = mx + b

y = -3/4x + 5/2

Problem of the Day:

Shtirlitz [24]

Answer:

Step-by-step explanation:

What this question is asking of you is what is the greatest common divisor of 12 and 15. Or, what is the biggest number that divides both 12 and 15.

in order to find this we have to split each number into it's prime components.

for 12 they are 2,2 and 3 (

⋅

)

and for 15 they are 3 and 5 (

⋅

)

Out of those two groups (2,2,3) and (3,5) the only thing in common is 3, so 3 is the greatest common divisor. That tells us that the greatest number of groups that can exist and have the same number of girls and the same number of boys for each group is 3.

Now to find out how many girls and boys there are going to be in each group we divide the totals by 3, so:

girls per group, and

boys per group.

(just as a thought exercise, if there were 16 boys, the divisors would have been (2,2,3) and (2,2,2,2), leaving us with 4 groups [

⋅

] of 3 girls [12/4] and 4 boys [16/4] )

a triangular flower bed needs a thin metal border all the way around it. The sides are 7 feet, 6 feet, and 9 feet long.

kotegsom [21]

Excuse my awful triangle drawing skills, haha..
So essentially you need to find the perimeter which is done by adding the lengths of the sides.. this gives you 22ft.
Then for part b you need to convert 22ft to yards which gives you 7.3 yards.
Since you can only buy a whole number of yards, you'll actually need 8 yards.
So if the boarder is $8.75 per yard, and you need 8 yards, how much would it cost?
Hope this was helpful.
