Enter the missing value into the box to complete the ratio comparing 500 meters to 3 kilometers

1 answer:

8 0

Before I tell you the answer, note that 1 kilometer equals 1,000 meters.
So, if 1 kilometer equals 1,000 meters, that means 3 kilometers equal 3,000 meters.

So the ratio is 500:3000

But let's shrink it down:
= 1:3000/500
= 1:6

Solve for x, 3ax+2b/c =4a

AfilCa [17]

Answer:

ANSWER = X = 4ac - 2b / 3ac

Step-by-step explanation:

Let's solve for x.

3a x + 2b / c = 4a

Step 1: Multiply both sides by c.

3acx + 2b = 4ac

Step 2: Add -2b to both sides.

3acx + 2b + −2b = 4ac + −2b

3acx = 4ac − 2b

Step 3: Divide both sides by 3ac.

3acx / 3ac = 4ac − 2b / 3ac

Answer = x = 4ac − 2b / 3ac

Find the value of a and m∠ZWT if ZW is an

nevsk [136]

If <span>ZW is an altitude of △XYZ, then m</span>∠ZWY = 90°

3a + 5 + 5a + 13 = 90
8a + 18 = 90
8a = 72
a = 72/8
a = 9

<span>m∠ZWT = 3a + 5 = 3*9 + 5 = 27 + 5 = 32</span>°

Answer:

Example 3. Same time problem: Upstream-Downstream.

First, let us explain the meaning of "upstream" and "downstream."

When a boat travels in the same direction as the current, we say that it is traveling downstream.

downstream

Thus if b is the speed of the boat in still water, and c is the speed of the current, then its total speed is

Downstream speed = b + c

When a boat travels against the current, it travels upstream.

upstream

In this case, its total speed is

Upstream speed = b − c

Problem. The speed of a boat in still water is 30 mph. It takes the same time for the boat to travel 5 miles upstream as it does to travel 10 miles downstream. Find the speed of the current.

Solution. The key to this type of problem is same time. That will give the equation,

Time upstream = Time downstream

Now, speed, or velocity, is distance divided by time -- so many miles per hour:

v = d

Therefore,

t = d

The equation will be

Time upstream = Time downstream

Distance upstream

Speed upstream = Distance downstream

Speed downstream

Let x be the speed of the current. Then according to the problem:

_5_

30 − x = 10

30 + x

Therefore,

5(30 + x) = 10(30 − x)

150 + 5x = 300 − 10x

5x + 10x = 300 − 150

15x = 150

x = 10 mph

What is the sum of the arithmetic series below? 2+5+8+......+59

konstantin123 [22]

Answer:

610

Step-by-step explanation:

((59 -2) / 3) + 1 = 20

Sum: (2 + 59) x (20 / 2) = 610

It's like a trapezoid with upper base length 2 and lower base 59 and height of 20.
