0.022 is your answer for this question.
To find the total combinations multiply each quantity together:
5 x 4 x 3 = 60
Answer: 60 different ways
Answer: Choice C, x ≤ -8
x is less than or equal to -8
put another way, x can be -8 or it can be smaller than -8
===============================================
We have some unknown number x, and we divide it by 2. The result is -4 or smaller. To find possible values for x, we need to solve for it. To do this, we multiply both sides by 2. Multiplication will undo division.
On the left side, the x/2 turns into x after you multiply it by 2.
On the right side, the -4 turns into -8 after you multiply it by 2
So that's how we go from x/2 ≤ -4 to x ≤ -8
Extra info: To graph this on a number line, plot a filled in closed circle at -8 on the number line. Then shade to the left of the closed circle. The closed circle says "include this value in the solution set". The shaded region represents all the values smaller than -8, eg the value -10.
Answer:
135
Step-by-step explanation:
if mK is 90 then mD is 60 and mS is 30. since the new point is in the middle of the triangle divide 60 and 30 by 2. Now mD is 30 and Ms is 15 so 30+15=45 so 180-45=135
Answer:
3. 9
4. 5 pounds
5. 5/12 of a pound
Step-by-step explanation:
3. "at least 3/8" means to include that column in the count.
4. 3(1/4) + 4(3/8 ) + 3(1/2) + 2(5/8)
= 3/4 + 12/8 + 3/2 + 10/8 but we need a common denominator. LMK in the comments if you need help with that
= 6/8 + 12/8 + 12/8 + 10/8
= 40/8
= 5 pounds.
5. For the average, we add up all the weights, then divide by the number of kittens. Thankfully, we just added everything up in #4. Since we're going to be dividing 5 by 12, we'll end up with a decimal. But since the whole problem was written in fractions, we'll keep it in fractions.
40/8 divided by 12 kittens
40/8 divided by 12 = 40/8 muliplied by the inverse of 12 which is 1/12
40/8 x 1/12
= 40/96
Our numerator and denominator can be evenly dived by 8, so the fraction is reduced to
= 5/12
