In one day, Annie traveled 5 times the sum of hours Brian traveled 2. Together they traveled 20 hours. Find the number of hours each person travels

Answer:

fg(7) = 231

Step-by-step explanation:

The question is asking you to find fg(7), which is function of f times function of g when x = 7. To solve it, you just need to plug in the 7 where x is in both equation and then multiply these results.

f(x) = x + 4

f(7) = 7 + 4

= 11

g(x) = 3x

g(7) = 3(7)

= 21

fg(7) = 11 × 21 = 231

Let us assume the total number of bowls of cereal that Nathan has eaten in a year = x

With each bowl of cereal, Nathan has 1/18 gallon of Milk.

In total the number of gallons of mulk in a year = 8 gallons,

Therefore, we frame the equation as shown below to calculate "x"

1/18 * x = 8

x = 18*8 = 144

Number of bowls of cereal Nathan ate in a year = 144 bowls

Answer:

Denote the two points are A and B, the balloon is C. Then we have,

Side AB = 9 miles

Angle CAB (angle A) = 27 deg

Ange CBA (angle B) = 45 deg

=> Angle ACB (angle C) = 180 - 27 - 45 = 108 deg

Applying the sine theorem:

AB/sinC = BC/sinA

=> BC = AB x sinA/sinC = 9 x sin27/sin108 = 4.3 miles

Denote CH as the height from C to side AB (or distance from ground to balloon), we have:

CH  = BC x sin B = 4.3 x sin*45 = ~3.04 miles

=> Distance from ground to balloon: ~3.04 miles

Hope this helps!

Answer:

3.0 miles

Step-by-step explanation:

Let h be the height

Tan(27) = h/b

h = btan(27)

Tan(45) = h/(9-b)

(9-b)tan(45) = h

(9-b)tan(45) = btan(27)

9tan(45) = b[tan(45) + tan(27)]

b = 5.962138633

h = btan(27) = 3.037861367

Answer:

38.4

Step-by-step explanation:

We have 8/2.5=3.2 What does this mean? Well, it means that (if the miles are porportional to the dogs) that means he will see 3.2 as many dogs. So, we have 12*3.2=38.4, or 38 if the homework is asking for a rounded number. Hope I helped!

Larry sees 12 dogs per 2.5 miles.

Your trying to find out how many dogs Larry sees in 8 miles.

So you want to find x.

To go from 2.5 to 8, you have to multiply by 3.2

So do the same thing to the denominator; 12 × 3.2=38.4

Since there are 38.4 dogs, you have to round down because 0.4 dogs is no dog.

Larry sees 38 dogs in 8 miles.
