Translate the sentence into an equation.

4vir4ik [10]

The translation of the given sentence into an equation is: 7(b + 3) = 1.

<h3>How to Translate a Sentence into an Equation?</h3>

Variables can be used to represent an unknown quantity when translating statements into equation. The word "times" is represented as or means "×" (multiplication). "Sum" means addition as well.

Thus, the sentence given can be translated as shown below:

The unknown number is represented as variable b.

"The sum of a number (b) and 3" would be translated as: b + 3.

"Seven (7) times the sum of a number and 3 (b + 3)" would therefore be: 7(b + 3).

Therefore, translating the whole sentence into an equation, we would have:

7(b + 3) = 1.

Thus, the translation of the given sentence into an equation is: 7(b + 3) = 1.

Put the following lengths in ascending order, 900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km.

matrenka [14]

Answer: 8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm

===========================================================

Explanation:

To be able to compare these various measurements, all of them must be the same unit. Let's convert each measurement to meters. If the measurement is already in meters, then we'll move onto the next measurement.

Here are some useful conversion factors

1 m = 100 cm
1 m = 1000 mm
1 km = 1000 m

With those conversion factors in mind, we get the following conversions:

900 cm = (900 cm)*(1 m/100 cm) = (900/100) m = 9 m
8.9 m = already in meters, moving on
895 cm = 8.95 meters; divide by 100 to convert from cm to meters as shown above
9.1 m = already in meters, moving on
12000 mm = (12000 mm)*(1 m/1000 mm) = (12000/1000) m = 12 m
0.0092 km = (0.0092 km)*(1000 m/1 km) = (0.0092*1000) m = 9.2 m

Here is the summary of the conversions:

900 cm = 9 m
8.9 m = 8.9 m
895 cm = 8.95 m
9.1 m = 9.1 m
12000 mm = 12 m
0.0092 km = 9.2 m

The original list of

{900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km}

becomes this equivalent list

{9 m, 8.9 m, 8.95 m, 9.1 m, 12 m, 9.2 m}

in that exact order.

After converting everything to meters, we can then sort the values from smallest to largest. Doing so gets us this sorted list of

{8.9 m, 8.95 m, 9 m, 9.1 m, 9.2 m, 12 m}

Then you convert back each measurement to its original form

{8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm}

which is the final answer.

A ball with mass m kg is thrown upward with initial velocity 28 m/s from the roof of a building 17 m high. Neglect air resistanc

lina2011 [118]

Answer:

The ball will take 6.3 seconds to reach the maximum height and hit the ground.

Step-by-step explanation:

a). When a ball was thrown upwards with an initial velocity u then maximum height achieved h will be represented by the equation

v² = u² - 2gh

where v = final velocity at the maximum height h

and g = gravitational force

Now we plug in the values in the equation

At maximum height final velocity v = 0

0 = (28)² - 2×(9.8)h

19.6h = (28)²

h = $\frac{(28)^{2}}{19.6}$

= $\frac{784}{19.6}$

= 40 meter

B). If the ball misses the building and hits the ground then we have to find the time after which the ball hits the ground that will be

= Time to reach the maximum height + time to hit the ground from the maximum height

Time taken by the ball to reach the maximum height.

Equation to find the time will be v = u - gt

Now we plug in the values in the equation

0 = 28 - 9.8t

t = $\frac{28}{9.8}$

= 2.86 seconds

Now time taken by the ball to hit the ground from its maximum height.

H = ut + $\frac{1}{2}\times g\times (t)^{2}$

(17 + 40) = 0 + $\frac{1}{2}\times g\times (t)^{2}$

57 = 4.9(t)²

t² = $\frac{57}{4.9}$

t² = 11.63

t = √(11.63)

= 3.41 seconds

Now total time taken by the ball = 2.86 + 3.41

= 6.27 seconds

≈ 6.3 seconds

Therefore, the ball will take 6.3 seconds to reach the maximum height and hit the ground.
