Answer:

Step-by-step explanation:

to figure this out, lets understand how decimals work

a decimal number in the tens place before the decimal

↓ here

0.00

that number will be the same number as the numerator or top number of a fraction in tenths

↓ here

0/10

so say it was 4/10 we needed to find, we would look on the number line for 0.40 like in answer choice B (NOT THE CORRECT ANSWER FOR THIS PROBLEM)

hope this helps you out on your work :)

Explain how to use the combine place value strategy to find 223 -119.

SashulF [63]

Combine place value strategy is useful if you try to subtract a number with bigger digits from a number with a smaller digit in the same place... such as now, where 3 is smaller than 9 in the ones place.

Then we can combine two place values: 23 and 19 and subtruct those. 23-19 is 4 (you can just count up from 19 to 23), so you know that the two will give the result of 04, and then you can proceed to the left: 2-1=1.

so the final result will 104.

A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, f(

Verizon [17]

For this case we have the following function:
f (t) = -16t2 + 48t + 100
The average rate of change is:
(f (t2) - f (t1)) / (t2 - t1)
We have then:
For t1 = 3:
f (3) = -16 * (3) ^ 2 + 48 * (3) + 100
f (3) = 100
For t2 = 5:
f (5) = -16 * (5) ^ 2 + 48 * (5) + 100
f (5) = -60
Substituting values:
AVR = (-60 - 100) / (5 - 3)
AVR = -80
Answer:
The average rate of change of f (t) from t = 3 seconds to t = 5 seconds is -80 feet per second.

Answer:

N(x) = 40 - 2x

P(x) = -2x² + 52 x - 240

maximum profit = 13

Step-by-step explanation:

given data

feeder cost = $6

average sell = 20 per week

price = $10 each

solution

we consider here price per feeder = x

and profit per feeder id here formula = x - 6

so that here

total profit will be

P (x) = ( x - 6 ) Nx

here N(x) is number of feeders sold at price = x

so formula for N (x) is here

N(x) = 20 - 2 ( x - 10 )

N(x) = 40 - 2x

so that

P(x) = (x-6) ( 40 - 2x)

P(x) = -2x² + 52 x - 240

since here

a = -2

b = 52

c = -240

a < 0

so quadratic function have maximum value of c - $\frac{b^2}{4a}$

so it will be

maximum value = -240 - $\frac{52^2}{4(-2)}$

maximum value = 98

so here maximum profit attained at

x = $\frac{-b}{2a}$

x = $\frac{-52}{2(-2)}$

x = 13

maximum profit = 13

Having spent $20.16 on ingredients, Jessica and Jonathan want to know how much they should charge for lemonade. Remember, they m

Usimov [2.4K]

<h3>They should charge $2.68 per lemonade serving in order to earn $20 profit in total.</h3>

Step-by-step explanation:

The amount spent on the ingredients = $20.16

The number of servings prepared = 15

The profit to b made in total = $20.00

Let us assume the minimum selling amount of per serve of lemonade = $ m

So, the selling amount of 15 per serving = 15 x ( cost of each serving)

= 15 x ( $ m) = 15 m

Now, Profit = Total Selling price - Total Cost price

⇒ $20 = 15 m - $20.16

or, 40.16 = 15 m

or, m = $\frac{40.16}{15} = 2.677333333$

⇒ m = 2.6773333

Now, rounding off to nearest hundredth, as 7 > 5 so 2,677333 ≈ 2.68

Hence, they should charge $2.68 per lemonade serving in order to earn $20 profit in total.
