Both pictures have a right triangle. Its hypotenuse = 5,

so D=5.

a longer leg C=4,

shorter leg B =3,

and A=7(side of the rectangle).

Each of the following is equivalent to a/b(bc + k)

Evgesh-ka [11]

All the mentioned options are similar to the given expression, except option B.

<h3>What is simplification?</h3>

Simplification refers to the process of making something simpler or easier to do or understand.

Given: $\frac{a}{b} (bc + k)$

On simplification ,we get:

$\frac{a}{b}(bc) + \frac{a}{b}(k) = ac + \frac{ak}{b} =a(c+\frac{k}{b})$

Now, we can see that the options A, C, D, E are similar but Option B is completely different.

Hence option B is the required answer, i.e., all the mentioned options are similar to the given expression, except option B.

Help!!!!

joja [24]

Answer:

0.28 yr

Step-by-step explanation:

To find the doubling time with continuous compounding, we should look at the formula:

$FV = PVe^{rt}$

FV = future value, and

PV = present value

If FV is twice the PV, we can calculate the doubling time, t

$\begin{array}{rcl}2 & = & e^{rt}\\\ln 2 & = & rt\\t & = & \dfrac{\ln 2}{r} \\\end{array}$

1. Samuel's doubling time

$\begin{array}{rcl}t & = & \dfrac{\ln 2}{0.055}\\\\& = & \textbf{12.603 yr}\\\end{array}$

2. Claire's doubling time

$\begin{array}{rcl}t & = & \dfrac{\ln 2}{0.05625}\\\\& = & \textbf{12.323 yr}\\\end{array}$

3. Samuel's doubling time vs Claire's

12.603 - 12.323 = 0.28 yr

It would take 0.28 yr longer for Samuel's money to double than Claire's.

It cost 4 people $65 to each buy a movie ticket and a

disa [49]

Answer:

C) 4t + 5.75 = 65

Step-by-step explanation:

This equation is correct because it adds together the price of one popcorn and the price of the 4 tickets as 4t.

A and B are wrong because only t should be multiplied by 4, and D is wrong because it subtracts the price of the popcorn.

Two thirds of the parade vehicles were vintage vehicles and 1⁄3 of the vintage vehicles were motorcycles. What fraction of the t

Liula [17]

Answer:the fraction of the total parade vehicles that are motorcycles is 2/9

Step-by-step explanation:

Let x represent the total number of parade vehicles.

Two thirds of the parade vehicles were vintage vehicles. This means that the total number of vintage vehicles would be

2/3 × x = 2x/3

1⁄3 of the vintage vehicles were motorcycles. This means that the total number of motorcycles would be

1/3 × 2x/3 = 2x/9

Therefore, the fraction of the total parade vehicles that are motorcycles would be

2x/9/x = 2/9
