Step-by-step explanation:
We can see that the graph is constant.=> the path of the dot/ the pattern is constant or not changing.
The balance was 18 when there were no visits.
It was 0 after 6 visits.
=>the amount spent on each visit is
Balance/number of visits= 18/6= $3
This can clearly be seen on the graph.
It may not work with a graph where the patter is not constant/ keeps on changing.
Answer:
30
Step-by-step explanation:
Equation y = 3x + 210
if y = 10x
10x = 3x + 210
or, 10x - 3x = 3x + 210 - 3x
or, 7x = 210
or, x = 210 ÷ 7
or, x = 30
Answer:
x = 16
y = 20
Step-by-step explanation:
the left part of the triangle can be solved first as it already has one angle and 1 side, we use trigonometry for this.
since we have 2 sides and 1 angle, to find the third side length we use the pythagoras theorem. a² + b² = c²
; 9² + 12² = c²
; 225 = c²
;√225 = c
; 15 = c
since we have all the lengths of the triangle, we can find out the angle opposite to the side length '9',
;
; x 9 = Sinx
36.86 = x
now, we look at the triangle as a whole, the top angle being 90 degrees, we know that we have 36.86.
; 90 - 36.86 = 53.13
; x Sin 90 = 20
y = 20
again, since we have 2 sides of a right angled triangle we use a² + b² = c²
we arrange this formula since we have the hypotenuse
; 20² - 12² = 256
; √256 = x
; 16 = x
Answer:
The probability that Jordan does not selects a salamander is or 0.55
Step-by-step explanation:
First, we will have to add up all of the number of animals.
55 + 33 + 12 = 100
Now, we find the ratio of 55 and 100 to get the probability.
55 / 100 = 11 / 20
So, the probability that Jordan does not selects a salamander is or 0.55
