Step 1

Given;

A\text{ small bottle of water holds 7 ounces of water}

Required; How many ounces of water do 9 bottles hold?

Step 2

To do this we will use the ratio;

\frac{1\text{ bottle}}{9\text{ bottles}}=\frac{7\text{ ounces}}{x}\begin{gathered} x=7(9) \\ x=63\text{ ounces} \end{gathered}

Answer;

9\text{ bottles of water holds 63 ounces}

Since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year. Predict th
BaLLatris [955]

Answer:

20,158 cases

Step-by-step explanation:

Let t=0 represent year 2010.

We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.

Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.

We can represent this information in an exponential decay function as:

F(t)=102,390(1-0.15)^t

F(t)=102,390(0.85)^t

To find number of cases in 2020, we will substitute t=10 in our decay function as:

F(10)=102,390(0.85)^{10}

F(10)=102,390(0.1968744043407227)

F(10)=20,157.970260446597\approx 20,158

Therefore, 20,158 cases  will be reported in 2020.

PLEASE PLEASE HELP <3
anzhelika [568]

Answer:

C

Step-by-step explanation:

∠ AFD = ∠ AFB + ∠ BFC + ∠ CFD

The 3 angles form a straight angle and sum to 180°, that is

4x + 5 + 6x + 3 + 5x + 7 = 180, that is

15x + 15 = 180 ( subtract 15 from both sides )

15x = 165 ( divide both sides by 15 )

x = 11

∠ CFD = 5x + 7 = 5(11) + 7 = 55 + 7 = 62°, thus

∠ AFE = ∠ CFD = 62° ( vertical angles are congruent )

What's an equivalent expression to 4(c+9)
sineoko [7]
4c + 36 because you have to multiple 4 x c which is 4c and then you have to multiply 4 by 9 which gives 4c + 36 (hope this helps)
