Hey the answer is 3 2/3!!!
hope i helped!!! :)))
Answer:
B. x < -4 and x > 3
Step-by-step explanation:
Factor and set = to 0
= 0
x = - 4 or x = 3 I call these critical values
The two numbers would divide a number line into 3 intervals. Pick a value in one of the intervals and put it in the original expression. If it makes the function positive, then all the values in that interval make the function positive. If the value you picked makes the function negative, then the values in the other intervals will make the function negative. Let's pick the value of 0 and substitute it into the function
We get + 0 - 12 = -12 which is not positive. Therefore, all the values between -4 and 3 will make the function negative. So, the values less than -4 or greater than 3 will make the function positive. Therefore, B is the correct answer.
Another way to do this problem is to graph the function and see where the graph is above the x-axis. But, sometimes it is not easy to graph the function.
The first one for the first y-intercept number is -1.
The second one is 5. (Not negative)
The third one is 11 (Not negative)
The fourth one is just 11 (Not negative as well)
The ones that say Not negative means that those numbers are postive.
I hope this helps though! :D
Answer:
The correct answer is the Pyramid II has a volume 63 cubic inches
Step-by-step explanation:
Formula:-
Volume of pyramid = 1/3(base area* height)
<u>To find the volume of pyramid I</u>
Length = 7 in
Breadth = 3 in
Height = 8 in
Base area = Length * breadth = 7 * 3 = 21 square inches
Volume = 1/3(base area* height) = 1/3(21 * 8) =56 cubic inches
<u>To find the volume of pyramid II</u>
Length = 6 in
Breadth = 3.5 in
Height = 9 in
Base area = Length * breadth = 6 * 3.5 = 21 square inches
Volume = 1/3(base area* height) = 1/3(21 * 9) = 63 cubic inches
Therefore the correct answer is the Pyramid II has a volume 63 cubic inches
1 mile = 3 ft
Therefore, the number of miles that equal 2800 ft is 2800÷3.
The answer: 933.33
