May = $24,890
May can be described as 100% (the starting amount)
We are increasing this amount by 4.9%
100% + 4.9% = 104.9%
We want a number that we can multiply by the original amount to get the new value
To turn a percentage into a multiplier, we divide by 100
104.9 / 100 = 1.049
Now, multiply 1.049 by the May sales to get the expected amount for June
$24,890 x 1.049 = $26,109.61
Expected Sales in June = $26,109.61
Answer:
2
Step-by-step explanation:
Take any 2 points on the graph,
(80, 90) & (40, 10)
Use the slope formula:

= (10-90)/(40-80)
= (-80)/(-40)
= 2
Hence, the slope is 2.

Answer:
4.75 pizzas per family
Step-by-step explanation:
19/4=4.75 or 4 and 3/4 pizza per family
formula for interior angles of a polygon is 180 times the number of sides minus 2
20 a 20gon has 20 sides, 20 -2 = 18, 180*18 = 3240
sum of interior angles = 3240 degrees

Answer:
The rule is: y = -10x+85
Step-by-step explanation:
The rule is given by:

Here m is the gradient and b is the y-intercept.
We have to take two pairs of input-output to find the rule
Let the two pairs be:
(x1,y1) = (1,75)
(x2,y2) = (2,65)
Slope is found using the formula:

Putting the values

Putting the value of slope

Putting a pair of input-output in the equation (1,75)

Putting the value of b

Hence,
The rule is: y = -10x+85
