Answer:

The father is 59

Step-by-step explanation:

lets say each of the kids are twelve

30*5=150-36=114=59+55

30*5+ 150 the age of everyone in the family added together

12*3= 36 the age of all the kids

150-36=114 the age of the adults added together

we know the mother is 4 years younger than the father so to state off you can take 114 and divide it by two to get what half of it is then take take numbers that are four apart to find the ages that add up to 114.

Answer:

5

Step-by-step explanation:

Step 1. Get two points off the graph

Points: (-70, 0) and (-60, 50)

Step 2. Use the two points to find the slope

m = slope

m = change in y/change in x

m = y2 - y1/x2 - x1

m = 50 - 0/-60 - -70

m = 50/10

m = 5/1

m = 5

The slope is 5

Answer:

Sales\ Price = \$9.60

Step-by-step explanation:

Given

Price = \$24.00

Discount = 60\%

Required

Determine the sales price

First, we calculate the discount price

Discount\ Price = Price * Discount

Discount\ Price = \$24.00 * 60\%

Discount\ Price = \$14.4

The sales price is then calculated by subtracting the discount price from the original price of the item

Sales\ Price = Price - Discount\ Price

Sales\ Price = \$24.00 - \$14.40

Sales\ Price = \$9.60

Find the distance between (8,-4,7) and (8,5,3)
Tems11 [23]

Answer:

sqrt(97)

Step-by-step explanation:

Since the x for both of the points are the same, we can reduce the problem to "find the distance between (-4, 7) and (5, 3)".

To do that, we can use the Pythagorean theorem, where <em>(change in x)^2+(change in y)^2 = (distance)^2:</em>

(5-(-4))^2+(3-7)^2=d^2

(9)^2+(-4)^2=d^2

81+16=d^2

97=d^2

d=sqrt(97).
