Answer:

2/15

Step-by-step explanation:

p(first white)=4/10=2/5;

P(second white)=3/9=1/3;

P(both white)=2/5 x 1/3=2/15

An

1/2

Step-by-step explanation:

There are 10 balls total and two balls are removed and not replaced so your fraction is 4/8 but you need to simplify it to 1/2

Answer: Yes, because they are similar triangles

Step-by-step explanation:

Let ABC be the right triangle with vertical side of 3 and a horizontal side of 7.

And, right angle at B,

Then, AB = 3, BC = 7 ⇒ AC = √58

Again let, DEF be the right triangle with vertical side of 9 and a horizontal side of 21.

And, right angle at E,

Then, DE = 9, EF = 21 ⇒ DF = 3√58

Thus, in triangles ABC and DEF,

Therefore,

By the property of similar triangles,

Since, in both triangles horizontal sides BC and EF are on X-axis,

Therefore,

The second one is correct

Answer:

Yes

explanation: they are similar triangles

The number that becomes 341 when rounded off to the nearest whole number is 340.511

In order to round off to the nearest whole number, take the following steps:

examine at the first digit after the decimal point, the tenth figure, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

• The first option - 340.111

• The tenth figure - 1 - is less than 5, so, 0 is added to the units term.  The number rounded off to the nearest whole number is 340. This is not the correct option.

• The second option - 340.151

• The tenth figure - 1 - is less than 5, so, 0 is added to the units term. The number rounded off to the nearest whole number is 340. This is not the correct option

• The third option - 340.411

• The tenth figure - 4 - is less than 5, so, 0 is added to the units term. The number rounded off to the nearest whole number is 340.This is not the correct option

• The fourth option - 340.511

• The tenth figure - 5 - is equal to 5, so, 1 is added to the units term. The number rounded off to the nearest whole number is 341. This is the correct option

Because we are rounding to the nearest whole number, we will look at the tenths place of the decimals, we see that it is .5 or higher, instead of the other ones that are .4 or lower.

The correct answer is 340.511

Answer:

d = ≈ 5.1 ( to 1 dec. place )

Step-by-step explanation:

to calculate the distance d use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (, 3) and (x₂, y₂ ) = (, 8)

d =√ ( - )² - (8 - 3)²

  = = ≈ 5.1
