Paul has decided to set up his own recording studio. He needs to purchase four speakers at $435 apiece and two mixers at $772 ap

Gnom [1K]

Answer: Paul can set up his studio and have $378 left over.

Step-by-step explanation:

In order to setup his own recording studio, he needs to purchase four speakers at $435 apiece. It means that the cost of 4 speakers is

4 × 435 = $1740

He also needs to purchase two mixers at $772 apiece. It means that the cost of 2 mixers is

772 × 2 = $1544

He also needs to soundproof a room, which will cost him $838. Therefore, the total cost of all he needs is

1740 + 1544 + 838 = $4122

If Paul has $4,500 in his savings account, then Paul can set up his studio and have $378 left over because

4500 - 4122 = $378

A car traveled at a constant speed. The graph shows how far the car traveled, in miles, during a given amount of time, in hours.

snow_tiger [21]

Answer:

Step-by-step explanation:

A car traveled at a constant speed as shown in the graph.

Distance traveled is on the y-axis and duration of travel on the x-axis.

Point A(3.5, 210) shows,

Distance traveled = 210 miles

Time to travel = 3.5 hours

So the point (3.5, 210) shows the distance traveled by the car in 3.5 hours is 210 miles.

Slope of the line = speed of the car = $\frac{\text{Distance traveled}}{\text{Time}}$

= $\frac{210}{3.5}$

= 60 mph

Now we will find the speed of the car at another point B(1, 60).

If the speed of car is same as the point B as of point A, point B will lie on the graph.

Speed of the car at B(1, 60) = $\frac{\text{Distance traveled}}{\text{Time}}$

= $\frac{60}{1}$

= 60 mph

Hence, we can say that point B(1, 60) lies on the graph.
