What's 10% ÷ 0.1%. I can't figure out why it's 10,000%.

Debora [2.8K]

Answer:

Step-by-step explanation:

10 % = 10/100 = .1

.1 % = .1 /100 = 1/1000 =.001

.1 ÷.001 =

10/100 ÷ 1/1000

Copy dot flip

10/100 * 1000/1 =

10000/100

100

Now we need to change it to percent

Multiply by 100%

100 * 100 %

10000%

Whats the solution system? 2x + 5y = 14 x + 3y = 16

S_A_V [24]

Answer:

Step-by-step explanation:

2x + 5y = 14 -------------(i)

x + 3y = 16 ----------------(ii)

To eliminate x, multiply the second equation by (-2)

(ii)*(-2) -2x - 6y = -32

(i) 2x + 5y = 14 { Now add & x is eliminated}

- y = - 18 {divide by (-1)}

y = 18

Plug in y =18 in Equation (i)

2x + 5*18 = 14

2x + 90 = 14

2x = 14 - 90

2x = -76

x = -76/2

x = -38

A traffic engineer records a sample of the types of vehicles that cross a bridge. She counts 112 passenger cars, 18 light trucks

Bond [772]

Answer:

The approximate probability that a random vehicle is a passenger car is 74.67%

Step-by-step explanation:

Probability

The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.

We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:

$\displaystyle p=\frac{112}{150}$

p = 0.7467

p = 74.67%

The approximate probability that a random vehicle is a passenger car is 74.67%
