D because 2/3 of the cards are odd and 64 is 2/3 of 94

Using a Ratio to solve

If we have a ratio of 7/12 odd cards to total cards she can expect to pull out 7 odds in her 12 cards. Now we will use this ratio out of 96 cards. If we have 96 cards with a 7/12 ratio we will divide 96 by 12 which is 8. Now we use our 8 and will multiply it by 7 which is our odd cards. Our total number of odds pulled out of 96 cards will be 56 out of 96.

jarptica [38.1K]

Answer:

Option d: {d | d ≤ 6} is the correct answer

Step-by-step explanation:

Given inequality is:

3(2d-1)\geq 4(2d-3)-3\\Expanding the terms\\6d-3 \geq 8d-12-3\\6d-3 \geq 8d-15\\Adding\ 3\ to\ both]\ sides\\6d-3+3\geq 8d-15+3\\6d\geq 8d-12\\Subtracting\ 8d\ from\ both\ sides\\6d-8d \geq 8d-12-8d\\-2d\geq -12\\Multiplying\ both\ sides\ by\ -1\\2d\leq 12\\Dividing\ both\ sides\ by\ 2\\d \leq 6

Hence, option d: {d | d ≤ 6} is the correct answer ..

Mrs. Morales wrote a test with 16 questions covering spelling and vocabulary. Spelling questions (x) are
fiasKO [112]

Answer:

<h3>5x+10y=100</h3>

Step-by-step explanation:

X+Y = 15

<h3>Sum of two types of question is 15</h3>

x+y-x = -x+15

<h3>y= -x+15</h3>

5(x)+10(y)=100

5x+10y=100

<h3>Total no. if points is 100</h3>

5x+10y-5x=-5x+100

10y= -5x+100

y=5/10x + 100/10

y= -1/2x+10

In a triangle, the middle length side is 3 more than the shortest side, and the longest side is double the middle length side. T
Tamiku [17]
Let's call the short side "s"
short side = "s"
middle side = 3s
longest side = 2*3*s
perimeter = 45 cm
perimeter = s + 3s + 6s = 45
short side = 4.5
middle = 13.5
long side = 27

4.5 + 13.5 + 27 = 45
