The answer is 283 1/3 pi because you have to find the volumes of each and then divide the hemisphere by 2 because its only half of a sphere and then add them together
Poor kid, next time ask your parents or teacher for help or try to find a smart friend that can help you. Go to bed if it is late and make sure you understand your homework before taking it home. Good luck!! :))
Substitute each value for x into the absolute value equation to solve this problem. Start with A. x = 4/5.
|(4/5) + 3| = 4(4/5) - 7
Add 4/5 and 3 inside the absolute value symbols, and multiply 4 times 4/5 on the right side of the equation.
|19/5| = 16/5 - 7
Subtract 16/5 and 7.
|19/5| = -19/5, which is a false statement because the absolute value of 19/5 is 19/5, and 19/5 does not equal -19/5. This cancels out A from our possible solutions.
Now substitute B. x = 10/3 into the equation.
|(10/3) + 3| = 4(10/3) - 7
Add 10/3 and 3 inside the absolute values, and multiply 4 times 10/3 on the right side of the equation.
|19/3| = 40/3 - 7
Subtract 40/3 and 7.
|19/3| = 19/3, which is a true statement so we can include B in our possible solutions. Check the box B.
Substitute C. x = -4/5 into the equation.
|(-4/5) + 3| = 4(-4/5) - 7
Solve as you did the other ones; add inside the absolute values and multiply and subtract 7 from the answer on the right side of the equation. After doing this you will get: 2.2 = -10.2, which is a false statement so C will be eliminated from possible answer choices.
Substitute the last one; D. x = -10/3.
|(-10/3) + 3| = 4(-10/3) - 7
Solving this you will end up with: 0.3 = -20.3, which is a false statement so the only answer choice that is a possible solution is B.
Answer:
henry sent 5 texts
Step-by-step explanation:
simple really. emily sent 20 which is 4 times as much as henry so to find out how many henry sent just divide emilies' number of texts by 4 to get 5 which is how many henry sent
In preparation of yourself in having to teach numeracy, it
is best to substantiate if learning the numeracy will have benefits or
advantages, such as having to help other people or even empower them as an
adult people learning and think of ways how will this could be important to
them.
