7 0

Ratio and proptin

choose/total=23/95
23/95=x/1000
times both sides by 95000
23000=95x
divide both sides by 95
242.1=x

My friend lives 225 km away it took 2.5 hours to drive there what speed was I doing

ollegr [7]

Remember the SI unit then you'll remember the formula. SI unit for speed is(ms-1). hence, just divide the distance with the time and you'll get the answer in(kmh-1)

A Lamborghini veneno and a ford pinto leave cities 1040 miles apart, speeding towards each other, The veneno’s speed is 180 mile

Kisachek [45]

Answer: The speed of the veneno is 220 miles per hour.

Step-by-step explanation:

We have the relation:

distance = speed*time.

We can model this situation as:

The cars will pass eachother when the sum of their distances traveled in the given time, 4 hours, is equal to the initial separation between them, 1040 miles.

So we have:

Sv = speed of the veneno.

Sp = speed of the pinto.

Sv*4hours + Sp*4hours = 1040 miles.

Now, we know that:

Sv = Sp + 180mph.

We want to find the speed of the veneno, so we should write:

Sp = Sv - 180mph.

Then we can replace this in our equation as:

Sv*4h + Sp*4h = 1040mi

(Sv + Sp)4h = 1040mi

(Sv + (Sv - 180mph))*4h = 1040 mi

(2*Sv - 180mph)*4h = 1040mi

2*Sv*4h - 720mi = 1040mi

Sv*8h = 1040mi - 720mi = 1760mi

Sv = 1760mi/8h = 220 mi/h

The speed of the veneno is 220 miles per hour.

Find the area of the figure below, formed from a triangle and a parallelogram.

IrinaK [193]

The area of the figure below is 96 mm².

The area of a shape is the amount of space occupied by a two dimensional figure.

From the diagram

Area of the triangle = (1/2) * base * height = (1/2) * (8 + 8) * 6 = 48 mm²

Area of the parallelogram = base * height = 8 * 6 = 48 mm²

Area of figure = 48 + 48 = 96 mm²

The area of the figure below is 96 mm².
