Answer:

Δ ABC is similar to Δ DBE by Angle-Angle similarity postulate.

Step-by-step explanation:

See the attached diagram.

Given that, Line ED ║ Line CA

Now, between Δ ABC and Δ DBE

(i) ∠ DEB = ∠ ACB {Corresponding angles as BC is the transverse line}

(ii) Again, ∠ BDE = ∠ BAC {Corresponding angles as AB is the transverse line}

(iii) Again, ∠ B is the common angle.

Therefore, Δ ABC is similar to Δ DBE by Angle-Angle similarity postulate. (Answer)

Kilani and Adrian are starting a nutrition program. Kilani currently consumes 1200 calories a day and will increase that number
Maurinko [17]

Answer:

7 days

Step-by-step explanation:

Let us represent the number of days = a

Kilani currently consumes 1200 calories a day and will increase that number by 100 calories each day.

1200 calories + 100 calories × a

1200 + 100a

Adrian currently consumes 3230 calories a day and will decrease that number by 190 each day.

3230 calories - 190 calories × a

3230 - 190a

The number of days that they would be consuming the same number of calories =

Kilani = Adrian

1200 + 100a = 3230 - 190a

Collect like terms

190a + 100a = 3230 - 1200

290a = 2030

a = 2030/290

a = 7 days

Therefore, the would be consuming the same number of calories in 7 days

If f(x) = 7 + 4x and g(x)=1/2x, what is the value of (f/g)(5)?
Romashka [77]
<h2>Answer:</h2>

d. \ \boxed{270}

<h2>Step-by-step explanation:</h2>

In this exercise we need to make a division and evaluate the new function at x=5. so we have two functions, namely:

f(x)=7+4x \ and \\ \\ g(x)=\frac{1}{2x}  

Therefore:

f(5)=7+4(5)=27 \\ \\ g(5)=\frac{1}{2\times 5}=\frac{1}{10}

So:

(f/g)(5)=\frac{27}{\frac{1}{10}}=270
