Answer:
190.9 in³
Step-by-step explanation:
Whenever one is asked to find how much(quantity of something) a certain container can hold,all you need to understand is that you are been asked about the volume of that container
We all know that the volume of a sphere is 4/3 × 22/7 × r³
And since we are dealing with a container in the shape of half a sphere,the volume of that container will now be volume of a sphere divided by 2
If the formula that was given initially was divided by 2,the new formula will look like this:
4/6 × 22/7 × r³
And we have the diameter but not the radius and we know that to find the radius, all we need to do is to divide the diameter by 2
That is 9/2 = 4.5
Putting the values in the formula,we can now derive the volume of that sphere
4/6 × 22/7 × 4.5³
= 190.9 in³ of soil
Answer:
2.89, rounded to the nearest hundredth
Step-by-step explanation:
Given that GPA is weighted by credits, we must first multiply each grade by its credit amount and sum those up to weigh the credits. Then, we divide by the total amount of credits to get the GPA per credit.
So, we start with math,
3.7 *5 + 1.8 *3 + 2.8 * 5 + 2.8 * 4 = 49.1 as the total GPA weighted per credit.
Then, to find the average per credit, we divide by the total amount of credits, which is 5 + 3 + 5 + 4 = 17.
Our answer is 49.1/17 = 2.89, rounded to the nearest hundredth
Answer:
x=2 y=1
Step-by-step explanation:
Solve the equations by substituting y=6x-11 into -2x-3y=-7.
-2x-3(6x-11)=-7
-2x-18x+33=-7
-20x+33=-7
-20x=-7-33
-20x=-40
x=2
To find y, substitute this value into the equation and solve for y.
y=6(2)-11
y=12-11
y=1
Sandi did not follow PEMDAS. She added before multiplying and dividing. Her answer should be 18 because 6 • 4 = 24, 2 / 2 = 1, 24 + 1 = 25, 25 - 7 = 18
