kayla is tracking the progress of her plants growth. today the plant is 8 cm high. the plant grows 2 cm per day.
a. write a linear model that represents the height of the plant after d days
b. when will the plant be at a height of 20 cm?
Answer:
30 cm
Step-by-step explanation:
A. Multiply daily rate by number of days and add that to the starting height:
Height = 2d + 8
B. Set height to 20 and solve for d:
20 = 2d +8
Subtract 8 from both sides
12 = 2d
Divide both sides by 2
D = 6
It wall take 6 days.

What is the total cost of a $250 table with a 5% tax rate
Answer: $262.50
Step-by-step explanation:
Paul Smith pays $50.00 a month for group health insurance. There is a $300 deductible. His medical bills for the last year were $2,600.00. Paul’s insurance company provided payment of 80% of the bills less the deductible. What was Paul’s total cost (including the monthly premium)?
Answer:
$1,360
Step-by-step explanation:
Take the monthly payment of $50 and multiply it by 12 because there is 12 months in a year which is $600. Next subtract $2,600 by your deduction of $300 which is $2,300. Then multiply by 20% because the insurance pays 80% leaving you with 20%, you get $460. Add $460 and $300 because those are the amounts you paid and you get $760. Now add the $600 to the $760 because of the monthly payment. The total comes out to $1,360.

What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.
Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor. Additionally, rounding and choosing the appropriate number of significant digits may be necessary during the process. To measure various parameters, various units of conversion are utilized.
Given that the radius of the moon is approximately 1,350,000 m. The radius in kilometers will be calculated as,
1 km = 1000m
1 m = 1 / 1000 km
1350000 meters = 1350000 / 1000 km
1350000 meters = 1350 km

A rectangle is (x + 6) meters (m) long and (2x - 1) meters wide.
(x + 6) m
(2x - 1) m
Which expression represents the area of the rectangle in square meters?
O 2x2 - 6
020? + 7-6
O 2012 + 112 - 6
202 + 13x - 6
Answer:
Option (3)
Step-by-step explanation:
Length of the given rectangle = (x + 6) meters
Width of the given rectangle = (2x - 1) meters
Area of a rectangle = Length × Width
= (x + 6)(2x - 1)
= x(2x - 1) + 6(2x - 1)
= 2x² - x + 12x - 6
= (2x² + 11x - 6) square meters
Therefore, area of the given rectangle is defined by the expression given in option (3).
