Step-by-step explanation:

if she can answer 50 in 20 mins then that means she is answering 2.5 questions in 1 min and then you must multiply 2.5 by the number of mins she has making it

12 x 2.5= 30

36 x 2.5= 90

Taya2010 [7]

Answer:

Number each of the treatments 1 — 3 and place them into a hat.

Step-by-step explanation:

Number each of the treatment I — 3 and place them into a hat. Shake the hat vigorously to mix the lumbers. Then for each plot of land, draw out a umber. The number drawn out from the hat will represent the treatment that will be imposed on the plot.

The number drawn out of the hat will be replaced and another number will be drawn for the next plot of land. Then, at the end of the experiment, the plant biomass of each plot will be measured and an average will be taken for all three treatments to determine which treatment had the greatest effect on plant biomass.

PLZZ HELP I AM GOING TO FAIL ( THIS WORTH 29 POINTS)
e-lub [12.9K]

Answer:

2248+2224.91= 4472.91

Step-by-step explanation:

A = $2,248.00

I = A - P = $248.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.1%/100 = 0.031 per year.

Solving our equation:

A = 2000(1 + (0.031 × 4)) = 2248

A = $2,248.00

The total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 3.1% per year for 4 years is $2,248.00.

A = $2,224.91

A = P + I where

P (principal) = $2,000.00

I (interest) = $224.91

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.7/100

r = 0.027 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,000.00(1 + 0.027/1)(1)(4)

A = 2,000.00(1 + 0.027)(4)

A = $2,224.91

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $2,000.00 at a rate of 2.7% per year compounded 1 times per year over 4 years is $2,224.91.
