What is the unknown fraction? 6/10 + ____ = 62/100

1 answer:

4 0

The answer is 2/100 or 1/50!

6/10 is equivalent to 60/100.
62/100 - 60/100 = 2/100 = 1/50

So, 6/10 + 1/50 = 62/100
6/10 + 2/100 = 62/100

(Use 1/50 because that’s the simplified answer!)

I hope this made sense! Good luck!

An auto travels at a rate of 25 km/hr for 4 minutes, then at 50 km/hr for 8 minutes, and finally at 20 km/hr for 2 minutes. find

ankoles [38]

We know that the formula for calculating distance is:

distance d = velocity v * time t

Calculating for each interval:

1: 25 km/hr for 4 minutes

d1 = (25 km / 60 min) (4 min) = 1.67 km

2: 50 km/hr for 8 minutes

d2 = (50 km / 60 min) (8 min) = 6.67 km

3: 20 km/hr for 2 minutes

d2 = (20 km / 60 min) (2 min) = 0.67 km

The total distance covered is:

d = d1 + d2 + d3

d = 1.67 + 6.67 + 0.67

d = 9 km

The average speed is:

s = 9 km (1000 m / km) / (14 min * 60 s / min)

s = 10.72 m / s

When they are both racing on hoverboards, Victoria is 3 times as fast as her brother Max. When she is on foot, she is 3 times sl

NARA [144]

Answer:

Race completed in 48 minutes.

Step-by-step explanation:

Let the speed of Max on hoverboard is = x

Then as per question speed of Victoria on hoverboard = 3x

Now it has been given in the question that speed of Victoria on foot is 1/3 of the speed of Max on hoverboard that will be = x/3

Now we will form the equation.

As we know the formula speed = distance/time

Let the time taken by both to complete the race be t minutes.

Distance covered by Victoria in 12 minutes + Distance covered by Victoria on foot = distance covered by Max on hoverboard

Then the equation will be

12(3x)+(1/3)x(t-12)=xt

$36x+\frac{xt}{3}-4x=xt$

$x(36+\frac{t}{3}-4)=xt$

$36+\frac{t}{3}-4=t$

$32=t-\frac{t}{3}$

$\frac{2t}{3}=32$

$t=\frac{(32)3}{2}=48$

So 48 minutes it took to complete the race.

What is the area, in square centimeters, of the isosceles trapezoid below?

charle [14.2K]

Both triangles area:
4.2 x 8.2 = 34.44

you don’t need to divide by two cause there’s two triangles anyways.

also, you get 8.2 by subtracting the total length by the top length. (13.5-5.3)

rectangle:
4.2 x 5.3 = 22.26

the total area is 56.7cm squared
