A father is 60 years old and his son is half his age how old was the boy when his father was four times his age

mr Goodwill [35]

F=60, s=60/2=30

(60-x)/(30-x)=4

60-x=120-4x

60+3x=120

3x=60

x=20

s=30-x

s=30-20

s=10

So the boy was 10 years old when his father was four times his age.

A countertop is 16ft long & 3ft wide what is the area in square meters

astra-53 [7]

ANSWER

Find out the area of the countertop in square meters .

To proof

As given

A countertop is 16ft long & 3ft wide.

A countertop is in the shape of the rectangle.

FORMULA

Area of a rectangle = length × breadth

long = 16ft

wide = 3ft

put the value

we get

Area of a countertop = 16 ×3

= 48 feet²

1 meter = 3.281 feet

$1feet = \frac{1}{3.281} meter$

convert Area of a countertop in square meters

$= \frac{48\times1\times1}{3.281\times3.281}$

= 4.461 m² ( approx )

Hence proved

The equation y 10x describes the amount of money Sandra earns, where x is the number of hours she

tester [92]

Answer:

a) $10 per hour

b) Sandra

Step-by-step explanation:

Complete Question:

The equation y 10x describes the amount of money Sandra earns, where x is the number of hours she works and y is the amount of money she earns

The table shows the amount of money Susan cams for different numbers of hours worked

Susan's Earnings

Time (h) Money Earned

5 40

8 64

10 80

(a) How much money does Sandra eam per hour? Show your work

(b) Who earns more per hour? Justify your answer

Answer:

y = 10x is sandra's equation. To find her hourly rate, we need to find how much she earns in "1" hour. Since x is hours, we plug in x = 1 and find y (which is her pay).

y = 10x

y = 10(1)

y = 10

$10 is Sandra's hourly rate.

To find who earns more per hour, we need to find the hourly rate of Susan as well from the table. Then compare.

5 hours = $40 so per hour is 40/5 = 8

8 hours is 64, so per hour 64/8 = 8

10 hours is 80, so 80/10 = 8

The table is justified at $8 per hour.

We know Sandra earns $10/hr and Susan earns $8 per hour. So Sandra earns more per hour.

Jack and Andrea want to create a right triangle together using values of x and y and the polynomial identity to generate Pythago

leva [86]

A right triangle can be considered as a special type because the relationship of its sides can be described using the hypotenuse formula:

c^2 = a^2 + b^2

c^2 = x^2 + y^2

where,

c is the hypotenuse of the triangle and is the side opposite to the 90° angle

while a and b are the sides adjacent to the 90° angle

In the problem statement, we are given that one of the side has a measure of 2 = x, while the hypotenuse is 5 = c, therefore calculating for y:

y^2 = c^2 – x^2

y^2 = 5^2 – 2^2

y^2 = 21

y = 4.58

The natural number is the number before the decimal. Therefore the answer is:

y = 4

A line passes through (-2,5) and has slope. What is an equation of the line in point-slope form?

shepuryov [24]

Answer:

Step-by-step explanation:

since the question does not have a given slope you can just put the point into the point slope formula y-y1 = m(x-x1)

y-5 = m(x-(-2))

y-5 = m(x+2)

since the slope is not given, leave it like that
