The hundredths place is where the 5 is.

Look to the right of the hundredths place and determine if the number is 5 or more or if the number is 4 or less.

In this problem, the number to the right of 5 is 1, and 1 is less than 4.

This means you can keep the 5 the same and every number after the 5 becomes imaginary zeroes.

3.95174 becomes 3.95 (rounded to nearest hundredth).

Two skiers are 30 kilometers apart and head towards each other. They meet in 2 hours. If the second skier is 5 kilometers per ho

DENIUS [597]

Answer:

Speed of first skier = 5 km/h

Speed of second skier = 10 km/h

Step-by-step explanation:

Given:

Distance between skiers = 30 km

Time after which they meet = 2 hours

Second skier is 5 km/h faster than the first skier.

To find speed of each skier.

Solution:

Let the speed of first skier be in km/h = $x$

Distance covered in km 2 hours will be = $Speed\times time=x\times 2=2x\ km$

Speed of second skier in km/h can be given as = $x+5$

Distance traveled by second skier after 2 hours will be = $Speed\times time=(x+5)\times 2=(2x+10)\ km$ [Using distribution]

Since, the skiers were 30 km apart initially, so the total distance covered by both of them when they meet after 2 hours will be = 30 km

Thus, we have:

$2x+2x+10=30$

Solving for $x$

$4x+10=30$

Subtracting both sides by 10.

$4x+10-10=30-10$

$4x=20$

Dividing both sides by 4.

$\frac{4x}{4}=\frac{20}{4}$

$x=5$

Speed of first skier = 5 km/h

Speed of second skier = $5+5$ = 10 km/h

Find the value of 14/8 + 15/12

n200080 [17]

Answer:

The value of $\frac{14}{8} + \frac{15}{12}$ = 3

Step-by-step explanation:

Explanation

Given $\frac{14}{8} + \frac{15}{12}$

L.C.M 8 , 12 is 24

$\frac{14}{8} + \frac{15}{12} = \frac{14 X 3 + 15 X 2}{24}$

= $\frac{42 +30}{24} = \frac{72}{24} = 3$

Final answer:-

The value of $\frac{14}{8} + \frac{15}{12}$ = 3

What is the distance between the lines y = 2x and y = 2x+5? Round your answer to the nearest tenth.

Ilia_Sergeevich [38]

The distance between both lines is 2.24 units

Step-by-step explanation:

There is no straight method to find the distance between two lines. The distance can be found out by finding a point on one line and then finding the distance of that point from the other line. The y-coordinate of point is obtained by putting any value of x in equation . The x and y combined give us the point.

Given

$y=2x\\Putting\ x=1\\y=2(1)\\y=2\\So, the\ point\ on\ y=2x\ is\ (1,2)$
