Answer:

red marbles

Step-by-step explanation:

Since the formula is;

Probability = number of required outcome

_______________________

number of possible outcome

3/8. = x/56

8x. = 168

x. 21 ( number of blue marbles)

Therefore if the total marbles = 56 and 21 of the marbles are blue then to get the red marbles

= 56 - 21

= 35

Answer:

Step-by-step explanation:

To evaluate f(2) substitute x = 2 into f(x), that is

f(2) = - (2)³ + 2(2)² - 3 = - 8 +2(4) - 3 = - 8 + 8 - 3 = - 3

9.1(6)+8.7(7)=_+60.9 How do I solve this?

timurjin [86]

Answer:

The answer is 54.6.

9.1(6)+8.7(7)=54.6+60.9

Step-by-step explanation:

Given:

9.1(6)+8.7(7)=_+60.9

Now, to solve it:

9.1(6)+8.7(7)=_+60.9

Let the _be x.

So, we remove parenthesis first that makes it multiply with the number next to it:

$9.1\times 6+8.7\times 7=x+60.9$

$54.6+60.9=x+60.9$

Now adding on L.H.S:

$115.5=x+60.9$

Subtracting on both sides by 60.9 we get:

$54.6=x$

$x=54.6$

Therefore, the answer is 54.6.

Please can someone help me solve the question in the picture 10 points plus brainliest!!!

Effectus [21]

Answer:

E. 2 1/2

E. 8.5 cm

C. 6 cm

Step-by-step explanation:

4............................

Scale factor = AE/AC = (4+6)/4 = 10/4 = 2.5

Correct option is E. 2 1/2

5............................

DE = ?

DE = √AD² - AE² = √15² - 10² = √125 = 5√3 ≈ 8.66

For measure of AD see next question (6)

Close option is E. 8.5 cm

6............................

AB = ?

AD/AB = 2.5 the scale factor as per question 4
(AB + 9)/AB = 2.5
2.5*AB = AB + 9
1.5*AB = 9
AB = 9/1.5
AB = 6 cm

Correct option C. 6 cm
