Caroline was thinking of a number. Caroline halves the number and gets 7.3. Form an equation with x from the information.

Damm [24]

Answer:

The equation is: $\frac{x}{2} = 7.3$

Step-by-step explanation:

Caroline was thinking of a number.

We are going to call this number x.

Caroline halves the number and gets 7.3.

To find half of a number, we multiply by 1/2. So

$\frac{1}{2} \times x = 7.3$

$\frac{x}{2} = 7.3$

A cheetah ran 275 feet in 3.23 seconds. How fast did the cheetah run in miles per hour? Round your answer to the nearest whole m

yawa3891 [41]

First we convert feet into meters, since 1 feet is 0.3048 m: 275 feet * 0.3048 = 83.82m.

Then we do: 83.82m / 3.23s = 25.9504644 m/s.

Then we convert that into miles per hour by 2.23694, so we do:

25.9504644 * 2.23694 = 58.0496318.

Then we round it to 58 mph.

So the answer is: The cheetah was running at 58 mph.

how high up on a building will 15 foot ladder reach if the foot of the ladder is placed 5 feet from the building? (be sure to in

mezya [45]

Use the Pythagorean theorem:
$5^2+x^2=15^2 \\
25+x^2=225 \\
x^2=225-25 \\
x^2=200 \\
x=\sqrt{200} \\
x=\sqrt{100 \times 2} \\
x=10\sqrt{2} \\
x \approx 14.14$

The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building.
