2,4,6,8,10
3,6,9,12,15
and your answer is 2/6

First you have to make them both common denominators
the common denominator is 6 so then half of 6 is 3 so it is 3/6 and then 1/3 converted to a denominator of 6 is 2/6 so the answer is 3/6+2/6= 5/6

A recipe for nut bread calls for 2/4 cup of walnuts and 1/6 cup of pecans. What is

sashaice [31]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

The question above is answered below.

$\frac{2}{4} + \frac{1}{6}$

Take the LCM of the denominators and simplify. The LCM is 12.

$\frac{6 + 2}{12}$

To get 6 + 2 above, we divide 12 by 4 which equals 3 then multiply 3 by 2, total 6. Similarly to get 2, we say 13 divided by 2, equals 2; 2 times 1 equals 2.

$= \frac{8}{12}$

The fraction above has to be simplified to reduced form. Thus the answer below.

$= \frac{2}{3}$

Therefore, the total amount of walnuts and pecans needed for the recipe is 2/3.

PLEASE HELP I NEED THIS

Alecsey [184]

Answer:

See below.

Step-by-step explanation:

1) 3 congruent sides and 3 congruent angles: equilateral, equiangular, acute

2) 2 congruent sides and a right angle: right isosceles

3) 2 congruent sides and an obtuse angle: obtuse isosceles

4) 1 obtuse angle and all different lengths of sides: obtuse scalene

5) 1 right angle and all different side lengths: right scalene

6) 2 congruent sides, all acute angles: acute isosceles

7) x + 2 = 10

x = 8

8) 10x + 3 + 10x + 3 + 34 = 180

20x + 40 = 180

20x = 140

x = 7

The probability that a car has a certain factory defect is 825. The probability that a car has a certain factory defect and need

ipn [44]

Answer:

90.91% probability that a car needs an oil change given that it has a certain factory defect

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem, we have that:

Event A: having a factory defect.

Event B: needing an oil change.

The probability that a car has a certain factory defect is 825.

So $P(A) = 0.825$

The probability that a car has a certain factory defect and needs an oil change is 750.

So $P(A \cap B) = 0.75$

What is the probability that a car needs an oil change given that it has a certain factory defect

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.75}{0.825} = 0.9091$

90.91% probability that a car needs an oil change given that it has a certain factory defect
