Step-by-step explanation:

1/10 is equivalent to saying 10/100.

Adding these together would look like:

10/100 + 6/100 = 16/100 (cannot be simplified)

a/b = 16/100

A salesperson earns $200 a week plus a 4% commission on her sales. Which equation models the relationship between her sales in a
Oduvanchick [21]

For this case we have:

Let:

  • s: Profit from sales in a given week
  • e: Seller's weekly profit

e = 200 + c

Where "c" represents the commission.

The commission on sales can be observed with the application of a rule of three:

s ---------> 100%

c ---------> 4%

c =\frac{4(s)}{100}

c =\frac{4s}{100}

Thus, e is given by:

e = 200 +\frac{4s}{100}

Answer:

The equation that models the relationship between her sales in a given week, s, and her weekly earnings, e is:

e = 200 +\frac{4s}{100}

Option d

for r=1 unit
[area of a circle]=pi*1²---------> pi units²

if the area a full circle of 360°--------------> is pi
the area of sector 88°------------------------> X
X=88*pi/360--------> 0.77 units²

A 4 foot tree was planted in 2012 outside a high school. The tree grew continuously by 22% each year from that point. Find out w
Brut [27]

Answer:

The height of the tree in 2020 was of 19.63 feet.

Step-by-step explanation:

Exponential equation for growth:

The exponential equation for the growth of an amount has the following format:

H(t) = H(0)(1+r)^t

In which H(t) is the amount after t years, H(0) is the initial amount and r is the growth rate, as a decimal.

A 4 foot tree was planted in 2012 outside a high school.

This means that H(0) = 4

The tree grew continuously by 22% each year from that point.

This means that r = 0.22

Find out what the height of the tree was in 2020.

2020 is 2020 - 2012 = 8 years after 2012, so this is H(8).

H(t) = H(0)(1+r)^t

H(t) = 4(1+0.22)^t

H(4) = 4(1.22)^t

H(4) = 4(1.22)^8 = 19.63

The height of the tree in 2020 was of 19.63 feet.
