What two fractions are equivalent to 3/10
d1i1m1o1n [39]

Answer:

6/20 and 9/30

Step-by-step explanation:

Any fraction that can be simplified to 3/10 by dividing the numerator and the denominator is considered equivalent. If you look at the fractions above 6/20 is literally the same thing as 3/10 but I just multiplied the 3 and 10 times 2. As long as you multiply/divide both the numerator and the denominator by the same number the answer you get should be equivalent.

Help me please and maybe explain how you go the answer
gregori [183]

Answer:

C.  x + 2y = 10

   -4x - y = 2

Step-by-step explanation:

A. quickest way is to plug in -2, 6  and see which one works

B. this is the other way

1. x + 2y = 10

-4x - y = 2

2. multiply 4 with  x + 2y = 10 so i can get 4x + 8y = 40

i want +4x so i can cancel with the -4x in  -4x - y = 2

3.

4x + 8y = 40

-4x - y = 2

--------------------

7y = 42

y = 6

4. then plug in 6 into an equation to get x

-4x - y = 2

-4x -6 = 2

-4x = 8

x = -2

Please help me on this one its the last one!
MA_775_DIABLO [31]

Answer:

9 cm

Step-by-step explanation:

Given that angle Y = 90 means that the triangle is a right angle triangle

If angle X = 30 degrees and xz =18 cm

xz is the hypotenuse side while zy is the opposite side considering the angle at X

Hence using the notation SOH CAH TOA

SOH

Sin X = zy/xz

Substituting

Sin 30 = zy/18

cross multiply

zy = 18 sin 30

zy = 18 * 0.5

= 9 cm

A card is chosen at random from a standard deck of 52 cards. What is the probability that the card is a Queen or a $\diamondsuit
DochEvi [55]

Answer:

probability that the card is a Queen or a diamond= 0.3269

Step-by-step explanation:

There are 4 queen in a deck of cards and 13 diamond in a deck of cards.

And a deck of cards contains 52 cards total.

Probability of the card selected to be a queen = number of queen/total number of cards

Probability of the card selected to be a queen =4/52

Probability of the card selected to be a queen= 1/13

Probability of the card selected to be a diamond= number of diamond/ total number of cards

Probability of the card selected to be a diamond=13/52

Probability of the card selected to be a diamond=1/4

probability that the card is a Queen or a diamond= Probability of the card selected to be a queen + Probability of the card selected to be a diamond

probability that the card is a Queen or a diamond= 1/13+1/4

probability that the card is a Queen or a diamond= 0.3269
