Describe a situation where it is easier to use decimals than friction,and explain why.

<span>Describe a situation where it is easier to use decimals than fractions and explain why:
</span>When you must multiply numbers that are NOT whole, decimals are easier to change in the sense that setting up a multiplication problem with decimals rather than fractions is much simpler and easier to calculate.

You and your friend are having a race, but since you are faster than him, you decide to give him a head start. He starts 10m in

Diano4ka-milaya [45]

Answer:

20 seconds

Step-by-step explanation:

Your friend starts 10 meters in front of the starting line.

You start from the starting line.

You run at 6 meters/ second.

Your friend runs at 5.5 meters/second.

You and your friend will be at the same distance from the starting line only when you are able to catch your friend.

The relative speed between you two is the difference in your speed and your friend's speed that is:

$6-5.5=0.5m/s$

So to cover 10 meters of separation at the speed of 0.5 meter/second it will take:

$t=\frac{10}{0.5}= \frac{100}{5}=20s$

So it will take 20 seconds for you and your friend to be at the same distance from the starting line.

Please Someone help me i got a question and i have a exams please help! i have attached the picture help me!

MAXImum [283]

Will recommend to keep in touch with picture as name of angles are based on it!

$\\$

So as you can see BA is parallel to DC as the arrow signs are made on it. And the figure has four sides , therefore we get to know that the above picture is of parallelogram.

$\\$

$\rm\angle B = \angle D$

How ?

As we know it's a parallelogram, so there's one property of parallelogram that opposite sides of Angle are equal.

$\\$

$\hookrightarrow \sf2x =130 \degree$

$\\$

$\hookrightarrow \sf x =130 \degree\div 2 \degree$

$\\$

$\hookrightarrow \sf x = \dfrac{130}{2}$

$\\$

$\hookrightarrow \sf x = \dfrac{13 \times 10}{2}$

$\\$

$\hookrightarrow \sf x = \dfrac{13 \times\cancel{ 10}}{\cancel2}$

$\\$

$\hookrightarrow \sf x = \dfrac{13 \times5}{1}$

$\\$

$\hookrightarrow \sf x =13 \times5$

$\\$

$\hookrightarrow \sf x =65 \degree$

$\\$

Now Let's find value of y.

$\rm \angle DAB =\angle DCB$

How ?

As we know it's a parallelogram, so there's one property of parallelogram that opposite sides of Angle are equal.

$\\$

$\dashrightarrow \rm x = y$

$\\$

$\dashrightarrow \rm 65 = y$

$\\$

$\dashrightarrow \bf y = 65 \degree$

$\\$

y + z + 60° = 180°

angles on same line

$\\$

65 + 60 + z = 180°
125° + z = 180°
z = 180° - 125 °
z = 55°

At last :-

x = 65°

y = 65°

z = 55°

What is the value of x if 10 – 25x = 5?

alina1380 [7]

10-25x=5

subtract 10 from both sides so 5-10 is -5

so now your left with -25x=-5 then divdie -25x by -5 and rememeber -5 divided by a negative is a positive and positive divided by a posivte is a positive and negavite divided by a positive is negavtive or positive divided by a negative is a negative

so when you divide -25x by -5 you get 5 so your answer is x=-5
