Answer:

q=8.5

Step-by-step explanation:

The ratio of the side lengths (AB) and (BC) is given. One is also given an expression for the side lengths of each of these sides. Set up a proportion to describe this scenario, then solve using cross products;

\frac{AB}{BC}=\frac{3}{4}

Substitute,

\frac{60}{10q+15}=\frac{3}{4}

Cross products,

\frac{60}{10q+15}=\frac{3}{4}

(60)(4)=(10q+15)(3)\\\\240=30q+45

Inverse operations,

240=30q+45\\\\195=30q\\\\8.5=q

A house on the market was valued at $245,000. After several years, the value increased by 9%. By how much did the house's value
aniked [119]

We are given that a house had a value of $245000 and its value was increased by 9%. To determine how much is this value increase in dollars we need to multiply the value of the house by 9/100. We get this:

245000\times\frac{9}{100}=22050

Therefore, the increase in dollars is $22050. Now, to determine the current value we need to add the increase to the previous value, we get:

245000+22050=267050

Therefore, the current value of the house is $267050.

I REALLY NEED HELP WORTH 10 POINTS URGENT!!!!!

Answer:

(f\circ g)(4)=31

Step-by-step explanation:

<u>Composite Function</u>

Given f(x) and g(x) real functions, the composite function named fog(x) is defined as:

(f\circ g)(x)=f(g(x))

For practical purposes, it can be found by substituting g into f.

We have:

f(x)=3x+1

g(x)=x^2-6

Computing the composite function:

(f\circ g)(x)=f(g(x))=3(x^2-6)+1

Operating:

(f\circ g)(x)=3x^2-18+1

Operating:

(f\circ g)(x)=3x^2-17

Now evaluate for x=4

(f\circ g)(4)=3(4)^2-17=48-17

\boxed{(f\circ g)(4)=31}
