dimaraw [331]

First, let's get rid of the unneeded info.

Oldest brother has $108 (3/5 the total)
Youngest brother has $x (1/10 the total)

Next let's find out the total. We do this by multiplying the oldest brothers money by 5/3 (the reciprocal).

108 × (5/3) = 180.

So the total amount of money is $180.

Finally, do 180 × (1/10) to find the youngest brother's amount.

180 × (1/10) = 18.

The youngest brother has $18.

The changing speed of a car is modeled by the function S(t) = −35t + 30, where t is time in seconds. Interpret the model

Flauer [41]

The car has an initial speed of 30 units and is slowing down by 35 units per second ⇒ answer C

Step-by-step explanation:

The form of the linear function is f(x) = m x + b, where

m is the rat of change
b is the initial value

The changing speed of a car is modeled by the function s(t) = -35t + 30, where t is time in seconds.

We need to interpret the model

∵ The changing speed of a car is modeled by s(t) = -35t + 30

- Compare between the model and the form of the linear function

∴ m = -35 and b = 30

∴ The initial speed is 30 units

∴ The speed is changing by -35 units per second

- If the value of change of the speed is negative, means the

car is slowing down by this rate

∴ The car is slowing down by 35 units per second

The car has an initial speed of 30 units and is slowing down by 35 units per second

Serjik [45]

Answer:

The scale used on his map is <u>150 miles : 2 inches</u>.

Step-by-step explanation:

Given:

Ted knows the actual distance between two cities is 150 miles. His map shows a distance of 2 inches between these cities.

Now, to find the scale Ted used on his map.

The actual distance Ted know between two cities = 150 miles.

The distance on map between these cities = 2 inches.

So, to get the scale used on his map:

$\frac{The\ actual\ distance\ Ted\ know\ between\ two\ cities}{The\ distance\ on\ map\ between\ these\ cities}$

$=\frac{150\ miles}{2\ inches}$

$=150\ miles:2\ inches.$

Therefore, the scale used on his map is 150 miles : 2 inches.
