So, possible numbers divisible by 10.
There are 10 of them in the first 100 positive integers.
10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.
And then the ones divisible by 3. There are 33.
3, 6, 9, 12, 15, 18, 21.. you get my point.
However, three of those are shared, 30, 60, and 90.
So basically add the two together and subtract three for the shared ones.
10 + 33 - 3 = 40
So there are 40 possibilities, so there is a 4/10 chance that the number is divisible by 10 or 3, so a 6/10 chance that the number is not divisible.
Or 3/5.
Answer:
Step-by-step explanation:
An intercept is where the line hits the axis.
Lets start with x. The x intercept is always going to be what x equals when y = 0. So we know the second value of the x intercept is going to be 0, because the second value is y. The line hits the x axis at -1.2, so the x intercept is -1.2, 0
The y intercept it what y equals when x equals 0. So the first value is going to be 0, to represent x. The line hits the y intercept at the point 0, -0.7.
Answer: Question 28 answer is larynx
Question 29:The vocal cords are two bands of smooth muscle tissue found in the larynx. The vocal cords vibrate and air passes through the cords from the lungs to produce the sound of your voice.
Question 30:The vocal folds produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs. This vibration produces the sound wave for your voice.
So its a straight line up and then straight line horizontal. Then a line down. Finally a line that goes up.
The width is w. the length is 2w - 4. to find area we would multiply these two together: w(2w - 4) & make sure to distribute the w to the 2w AND the -4. so the answer to this question would be 2w^2 - 4w (c). hope this helps!
