A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles. Find P (red or blue)

1 answer:

6 0

The answer is B.

If there are 6 red marbles, 6 white marbles, and 4 blue marbles, then there are 16 marbles total. To find the probability (P) of either the red or blue marbles, you will add together the number of red and blue marbles, and divide that by the total:

(6 + 4) / (6 + 6 + 4)
10/14

This fraction can further reduce to 5/8 (by dividing both the numbers by 2).

How do I solve this

hichkok12 [17]

You wanna find a common denominator so put the problem like this

3 1/3.< You wanna take 3 (denominator)
And times it
By 5 then you wanna take the 5. - 2 2/5.< (deniminator) and times it by 3.
____ Your common denominator is 15

now it will look like this

3 1/15

-2 2/15
———-

Now subtract. You will need to borrow 1 from 3 since you cant subtract 2 by 1 so the 3 will become a 2 and the 1 will be come 11 and here you can subtract so this will be your answer.

2 11/15

-2 2/15
-———-
0 9/15

Thats your official answer 9/15 hope I helped :)

SOMEONE PLZZZ HELP ME THIS IS DUE IN LIKE 5 MINS (I WILL MARK BRAINLIEST)

andrew-mc [135]

Answer:

1) x = 8

2) ∠RPS = 36°

Step-by-step explanation:

GIVEN :-

∠QPS = 180°
∠QPR = 7x + 88
∠RPS = 3x + 12

TO FIND :-

Value of x
Measure of ∠RPS

FACTS TO KNOW BEFORE SOLVING :-

In a straight line , if there are two angles such that their sum is equal to straight angle (or 180° in other words) , then those angles are known as linear pair.

PROCEDURE :-

Measure of ∠QPS = 180° and it comprises of ∠QPR & ∠RPS.

⇒ ∠QPR & ∠RPS are linear pair.

⇒ ∠QPR + ∠RPS = 180°

⇒ 7x + 88 + 3x + 12 = 180°

⇒ 10x + 100 = 180

⇒ 10x = 180 - 100 = 80

⇒ x = 80/10 = 8

x = 8. So,

∠RPS = 3×8 + 12 = 24 + 12 = 36°

Find the volume of a box that has a length of 7 cm, a width of 9 cm, and a height of 11.2 cm.

astra-53 [7]

The answer is 705.6 cm^3.

Remember that volume of a box, rectangular prism, is: V = LWH.

So, V = 7(9)(11.2) = 705.6 cm^3
