An executive invests $22,000 some at 7% ad some at 6% annual interest. If he receives an annual return of $1,420, how much is in
34kurt

Answer:

he invested $10,000 at 7% and $12,000 at 6%

Step-by-step explanation:

  • There are 2 equations that appear from this problem
  • X+Y=22,000 and 0.07x + 0.06y = 1420
  • Lets start by simplifying X+Y=22000

Y = 22000 - x

  • now plug this into the Y value for the other equation

0.07x + 0.06(22000-x) = 1420

0.07x + 1320 -0.06x = 1420

0.01x = 100

X = 10000

  • now plug 10000 into x for the simplified equation

Y = 22000 - 10000

Y = 12000

Owners of a recreation area are filling a small pond with water. Let y represent the total amount of water in the pond (in liter
devlian [24]

Answer:

  1. 32
  2. 400

Step-by-step explanation:

Lets start by defining the numbers in the equation.

This  equation is in slope-intercept form meaning that it is y=mx+b or y = b+mx they are both the same

In slope-intercept form,

  • m = slope or rate
  • and b = y-intercept

Th equation is y=400+32x so now we know

  • b=400
  • and m=32

For the first question the change per minute is the rate so it is <u>32.</u>

For the second question the starting amount is the same as the y-intercept so it is <u>400.</u>

45.3297 rounded to the nearest tenth would be?
Alex
45.3297 rounded to the nearest tenth is 45.3
3 is in the tenths place, so you look at the number to the right of it. If that number is 5 or more, you round up. If the number is 4 or less, you round down. So you round 45.3297 down to 45.3
