3×168=504
Answer:
168 ⇒ 11176 ⇒ 7504 ⇒ 3Step-by-step explanation:
We know 1 week has 168 hours. To find out the amount of weeks if you know only the hours you do Y = X/168
If you know the weeks and not the hours, you do X = Y*168
In both equations above, X is the hours and Y is the weeks

Using historical population data, Jasper determines the logistic regression equation y =
214
1+ 16.4e-0.05%
for the
population, in thousands of people, of his town after x years.
To the nearest thousand people, what is the projected population 30 years from now?
46,000 people
O 55,000 people
143,000 people
О 214,000 people
Answer:
46,000
Step-by-step explanation:
do the 16.4e part first, substitute x for 30 then add 1 = 4.66ish
214/4.66 rounded is about 46 so probably 46,000
The perimeter of the triangular park shown on the right is 11x - 7. What is the missing length?
Answer:
6x-4
Step-by-step explanation:
the perimeter is the distance around the shape, we get this by adding all the sides, call the missing side y and set up an equation for the perimeter
11x-7 = 4x+2 + x-5 + y
solve for y
11x-7 = 5x -3 + y
11x-4 = 5x + y
6x-4 = y

A rhombus has 10-in.Sides, two of which meet to form the indicated angle. Find the area of the rhombus.(Hint: Use a special right triangle to find height.) The angle is 30 degrees.
Answer:
50 in²
Step-by-step explanation:
Given that the side of the rhombus is 10 in, and it has an angle of 30°
The formula for the angle in a rhombus is given as
Sin Φ = height / side
Sin 30 = height / 10
height = 10 * sin 30
height = 10 * 0.5
height = 5 inches
One of the formulas for calculating the area of a rhombus is given as
Area = height * side, and thus, we have
Area = 5 * 10
Area = 50 square inches.
Therefore, the area of the rhombus is calculated to be 50 in²
