Answer:

Step-by-step explanation:

Cynthia completed 2/3 of the items on her to do list in the morning and finished 1/8 of the items during her lunch break. This means that the fraction of her to do list that is finished by the end of her lunch break would be

1/8 + 2/3 = (3 + 16)/24 = 19/24

Therefore, the fraction of her to-do list that she still have to do after lunch would be

1 - 19/24 = (24 - 19)/24 = 5/24

Movie posters sell for $2.89 each, with a 25% discount if 15 or more posters are purchased. Sales tax is 6%. If Lois buys 20 pos
devlian [24]

Answer:

The posters cost $52.07.

Step-by-step explanation:

First, you have to calculate the cost of the 20 posters by multiplying the price per poster for the quantity:

$2.89*20=$57.8

Then, you have to calculate the 15% discount by multiplying the cost for 15% and subtracting that amount from the cost:

$57.8*15%=$8.67

$57.8-$8.67=$49.13

Finally, you have to calculate the 6% of $49.13 and add the result to that amount:

$49.13*6%=$2.94

$49.13+$2.94=$52.07

According to this, the answer is that the posters cost $52.07.

Drag the descriptions of each investment into order, from which will earn the least simple interest to which will earn the most
Anna007 [38]

Answer:  Third investment is the least simple interest and Second investment is the  most earned simple interest.

Step-by-step explanation:

Since we have given that

Investment of $3,000 at 5% simple interest for 20 years .

Simple interest would be

\dfrac{3000\times 5\times 20}{100}\\\\=\$3000

Investment of $1,000 at 16% simple interest for 20 years

Simple interest would be

\dfrac{1000\times 16\times 20}{100}\\\\=\$3200

Investment of $3,000 at 16% simple interest for 2 years.

Simple interest would be

\dfrac{3000\times 16\times 2}{100}\\\\=\$960

Hence, Third investment is the least simple interest and Second investment is the  most earned simple interest.

What are th zeros of f(x)=x(x-8)
Andrews [41]
Hi there!

Let's solve this problem step by step!
The zeros of a function are the input values that produce an outcome of 0. To find this input values we must set up and solve an equation.

f(x) = x(x - 8)
Set up the equation

f(x) = 0 thus x(x - 8) = 0

Now use the rule AB = 0 gives A = 0 or B = 0. This rule basically means that if we have a product that equals 0, at least one of the factors must be 0.

Hence, we get the following:
x = 0 \: \: or \: \: x - 8 = 0

Finally add 8 to both sides in the right equation.
x = 0 \: \: or \: \: x = 8

The zeros of the function are 0 and 8.
