Answer:

10%

Step-by-step explanation:

In this question, we are asked to calculate the percentage error in a measurement.

This can be obtained by first getting the error involved. That is calculated by Subtracting the value calculated from the actual value. That is 9.5 - 8.9 = 0.6

The percentage error is thus 0.6/9.5 * 100 = 6%

The value is actually 10% to the nearest tenth of a percent

20/216 = 0.0925925

0.0925925 * 64 =5.9259"

How many solutions does the system of equations below have? y = 7 6 x + 6 7 y = 9 2 x − 4 9
Mila [183]

Answer:

Im not sure what type of solution you are looking for. You should be more specific. Though I will still give you some helpful solutions and you use the one you need.

Step-by-step explanation:

Factored: y=168x+67y-49

Solved for Y; -28x/11 + 49/66

Solved for X: -11y/28 + 7/24

X and Y intercepts:

X=( 7/24, 0 )

Y= ( 0, 49/66 )

I hope these answers help. Next time be more specific to what your looking for and make sure your equation is written correctly.

1. Jadyn started off his long division problem incorrectly. What is his mistake?
Anastaziya [24]

The mistake Jadyn made in the long division is

  • Mistake in subtraction
  • the first quotient

<h3>What is long division ?</h3>

Long division refers to a way of dividing large numbers

performing the long division correctly gives

divisor    dividend     quotient     multiplication    subtraction  new dividend

8             335              40               8 * 40 = 320     335 - 320       15          

8             15                 1                   8 * 1 = 8            15 - 8                7  

8             70                0.8               8 * 8 = 64      70 - 64                6

8             60                0.07             8 * 7 = 56       60 - 56               4

8             40                0.005           8 * 5 = 40       40 - 40               0

The quotient is then added as

40 + 1 + 0.8 + 0.07 + 0.005 = 41.875

jarptica [38.1K]

Answer:

20 red tiles

Step-by-step explanation:

14 green tiles,10 red tiles, and 16 blue tiles. = 40 tiles

P(red) = 10/40 = 1/4

If we draw 80 tiles

80 * 1/4 = 20

We should expect 20 red tiles
