Answer:

107.500

Step-by-step explanation:

5.450.000-75.000=5.375.000

5.375.000:12 1/2=5.375.000:25/2=5.375.000*2/25=430.000

430.000:4=107.500

+ and - ,

* and :

are inverse operations

Where it is an operation and the result is a number , we have to do the inverse operation for finding the initial number.

verifying :

107.500*4*12 1/2+75.000=5.450.000

Convert 72°F to °C (to the nearest tenth) using one of the following formulas: F = 9/5xC + 32 or C = (F - 32) x 5/9.

Fudgin [204]

First set up the equation:
$C=(F-32)\times\frac{5}{9}$
Then substitute in known values:
$C=(72-32)\times\frac{5}{9}$
and solve for C
$C=40\times\frac{5}{9}$
$C=22.22$

5. An airplane takes 4 hr to travel a distance of 4100 km. Another airplane travels at a speed

Mazyrski [523]

Answer:

4.969696 hours

Step-by-step explanation:

The distance traveled is shown through the following equations

Distance = velocity * time

This means that

4100=velocity*4

This means that ariplane 1 travles at 1025 km/hr

We can then subtract 200 from this to find that airplane two travels at a speed of 825 km/hr

Now we need to find how long it takes for that plane to travel 4100

So using the same equation

4100=825*time

Divison will tell us that the answer is around 4.9696 hours which is pretty much 5

Drag and drop the constant of proportionality into the box to match the table. If the table is not proportional, drag and drop "

Nikitich [7]

The table is proportional and the constant of proportionality is 1.5

Step-by-step explanation:

Proportional relationships are relationships between two variables

where their ratios are equivalent

One variable is always a constant value times the other
The relation between the two variables represented graphically by a line passes through the origin point

The table:

→ x : 0 : 2 : 4 : 6

→ y : 0 : 3 : 6 : 9

To prove that y ∝ x find the ratio between each value of y with corresponding value of x

∵ $\frac{3}{2}=1.5$
