Answer: F-23=45

Step-by-step explanation:

The addition property of equality means that if:

A = B

then we can add the same thing in both sides of the equation, and the equality will remain balid, so:

A + C = B + C.

Then, the correct answer is the last option:

F - 23 = 45

Then we can add the same number to both sides, we can add 23 to both sides and in this way isolate F:

F - 23 = 45

(F - 23) + 23 = 45 +23 = 68

F + (23 - 23) = 68

F = 68

The circle passes through the point (4.5,0). What is its radius?

Andreyy89

Answer:

4.5 units

Step-by-step explanation:

In this case, if we draw the point on the xy cartesian plane, we know that the value of "x" is 4.5 and the value of "y" is 0.

Which means that when I draw this in any way, the maximum value it will take is 4.5 units, therefore the radius should not exceed this value, nor should it be less than 4.5 units since the circle would be distorted.

Which means that the radius is 4.5 units

Tomtit [17]

Answer:

1 cm^2 = 100 mm^2

9 cm^2 = 900 mm^2

5.2 cm^2 = 520 mm^2

1 dm^2 = 100 cm^2

17 dm^2 = 1700 cm^2

4.3 dm^2 = 430 cm^2

1 m^2 = 10000 cm^2

7 m^2 = 70000 cm^2

2.5 m^2 = 25000 cm^2

1 km^2 = 1000000 m^2

50 km^2 = 50000000 m^2

8.5 km^2 = 8500000 m^2

Step-by-step explanation:

1 cm = 10 mm

1 $cm^{2}$ = 10×10 $mm^{2}$ = 100 $mm^{2}$

9 $cm^{2}$ = 9×100 $mm^{2}$ = 900 $mm^{2}$

5.2 $cm^{2}$ = 5.20×100 $mm^{2}$ = 520 $mm^{2}$

1 dm = 10 cm

1 $dm^{2}$ = 10×10 $cm^{2}$ = 100 $cm^{2}$

17 $dm^{2}$ = 17× 100 $cm^{2}$ = 1700 $cm^{2}$

4.3 $dm^{2}$ = 4.3 × 100 $cm^{2}$ = 430 $cm^{2}$

1 m = 100 cm

1 $m^{2}$ = 100×100 $cm^{2}$ = 10000 $cm^{2}$

7 $m^{2}$ = 7×10000 $cm^{2}$ = 70000 $cm^{2}$

2.5 $m^{2}$ = 2.5×10000 $cm^{2}$ = 25000 $cm^{2}$

1 km = 1000 m

1 $km^{2}$ = 1000×1000 $m^{2}$ = 1000000 $m^{2}$

50 $km^{2}$ = 50×1000000 $m^{2}$ = 50000000 $m^{2}$

8.5 $km^{2}$ = 8.5×1000000 $m^{2}$ = 8500000 $m^{2}$

The rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet

<h3>How to determine the rock's height?</h3>

The function is given as:

d = √216 +h²

At a distance of 100 feet, it means that:

d = 100

So, we have:

√216 +h² = 100

Take the square of both sides

216 +h² = 10000

Subtract 216 from both sides

h²= 9784

Take the square root of both sides

h = 98.9

Hence, the rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet
