Answer:
80 children attend this day care,
Step-by-step explanation:
Let x represent the number of children that attend this day care center. The day care worker found 28 children absent one day during an epidemic of chicken pox.
If this was 35% of the total number of children attending the day care center, it means that the number of children absent one day during the epidemic of chicken pox can be expressed as
35/100 × x = 0..35×x = 0.35x
Therefore,
0.35x = 28
x = 28/0.35= 80
Answer:
Step-by-step explanation:
Plot that point in the x/y coordinate plane to see that it sits in the third quadrant. From the point, draw a line to the origin, constructing a right triangle. The side adjacent to the angle is -2, the side across from the angle is -5, so we need to find the length of the hypotenuse using Pythagorean's Theorem:
and

Step-by-step explanation:
Just follow the equation left to right
Answer:
$21 the minimum Bob has to may will be the amount payed regardless of the number of passengers in the taxi
Let
x-------> the first number
y-------> the second number
P-----> product
we know that
x+2y=56----------> 2y=56-x-----> y=28-0.5x------> equation 1
P=x*y----> equation 2
substitute equation 1 in equation 2
P=x*[28-0.5x]-----> P=28x-0.5x²
using a graph tool
see the attached figure
the vertex is the point (28,392)
that means
for x=28
the product is 392 (maximum)
find the value of y
y=28-0.5x----> y=28-0.5*28----> y=14
the answer isthe numbers are 28 and 14
