You only told us the length of 3 sides, and from those 3,
we can already see that it's not a rectangle.  (If you take
any 3 sides of a rectangle, two of them must be the same
length.)

So we have no way to tell the length of the 4th side, or to
add up the lengths of all 4 sides to get the perimeter.
It could be many different things.

The only thing we know for sure is that the perimeter must be
more than  2.55 meters.  (That's the sum of the 3 sides you gave us.)

Well if you divide 2 and 10 you get 5 and if you divide 5 and 45 you get 9 so the answer would be 59

The table below shows the numbers of vanilla,
Annette [7]

Answer:

marcia must have sold at least 22 chocolate cones.

Step-by-step explanation:

Jan sold a total of 65 cones (20+15+30). Tomas sold a total of 68 cones (20+18+30).

If Marcia sold more cones than Jan or Tomas, she had to have sold more than 68 cones in total. 30+17 = 47. I subtracted 68-47, to see how many chocolate cones she should have sold to match the number of cones Tomas sold, which is 21 chocolate cones. Therefore, to surpass Tomas in the total number of cones sold, she had to have sold at least 22 chocolate cones.

What are the next 3 numbers in this pattern of integers -2, -1, -1, 0, -1, 1, -2
sashaice [31]

Answer:

The next 3 numbers to the given pattern of integers is -2,-1,-1,0,-1,1,-2 are 3,-5,8

Step-by-step explanation:

Given pattern of integers is -2,-1,-1,0,-1,1,-2

To find their next 3 numbers of the given pattern :

Let a_{1}=-2

a_{2}=-1

a_{3}=a_{1}-a_{2}

=-2-(-1)

=-2+1

Therefore a_{3}=-1

a_{4}=a_{2}-a_{3}

=-1-(-1)

=-1+1

Therefore a_{4}=0

Similarly we have a_{5}=-1 ,a_{6}=1 ,a_{7}=-2

The general form to the given pattern is

a_{n}=a_{n-2}+a_{n-1}  for n={\{1,2,3,4,5,6,7,8,9,10}\}

Therefore to find the a_{8},a_{9},a_{10}

Put n=8 in a_{n}=a_{n-2}-a_{n-1}

a_{8}=a_{8-2}-a_{8-1}

=a_{6}-a_{7}

=1-(-2)

a_{8}=3

Put n=9 in a_{n}=a_{n-2}-a_{n-1}

a_{9}=a_{9-2}-a_{9-1}

=a_{7}-a_{8}

=-2-(3)

a_{9}=-5

Put n=10 in a_{n}=a_{n-2}-a_{n-1}

a_{10}=a_{10-2}-a_{10-1}

=a_{8}-a_{9}

=3-(-5)

a_{10}=8

Therefore the next 3 numbers are 3,-5,8

Determine the intercepts of the line that passes through the following points (10,20) (15,12) (20,4)
Novay_Z [31]

Answer:

x intercept is (45/2,0)

y intercept is (0,-36)

Step-by-step explanation:

Slope intercept form of equation of line is

y=mx+b where m is the slope and b is the y intercept

use any two points to find the slope

(10,20) (15,12)

slope = \frac{y_2-y_1}{x_2-x_1} =\frac{12-20}{15- 10} = \frac{-8}{5}

m = -8/5

now we find out b using (10,20)

20 = \frac{-8}{5} (10)+b

20 = -16 + b

add 16 on both sides , so b = 36

b is the y intercept , so y intercept is (0,-36)

Now we find x  intercept

equation of line is y=mx+b that is y = \frac{-8}{5}x+36

To find x intercept plug in 0 for y

0= \frac{-8}{5}x+36

subtract 36 on both sides

-36= \frac{-8}{5}x

Multiply by -5/8 on both sides

-36*\frac{-5}{8}=x

\frac{45}{2}=x

x intercept is (45/2,0)
