What is the volume of the solid if a 6 inch (diameter hole is drilled all the way
Answer:
1,467.6 cm³
Step-by-step explanation:
Volume of the solid = volume of the rectangular prism - volume of the cylinder
= L*W*H - πr²h
L = 12
W = 10
H = 16
r = ½(6) = 3
h = 16
Plug in the values
Volume of the solid = 12*10*16 - π*3²*16
= 1,920 - 452.40
= 1,467.6 cm³

If f(x)=-2xsquared+x-5 what is f(3)
9514 1404 393
Answer:
-20
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
f(3) = -2·3² +3 -5
f(3) = -2·9 +3 -5 = -18 +3 -5 = -15 -5
f(3) = -20
_____
Sometimes it is easier to evaluate polynomials when they are written in Horner form:
f(x) = (-2x +1)x -5
f(3) = (-2·3 +1)(3) -5 = -5(3) -5 = -20

1
ton per minute.
How much sand is in each dump truck when the trucks are the same weight?
Enter your answer in the box.
Answer:
Step-by-step explanation:
A. For this case, the first thing we must do is define variables.
We have then:
t: time in minutes
The linear equation that represents the problem is given by:
w (t) = (1/4) t + 11.25
Answer:
An equation for W in terms if T is:
w (t) = (1/4) t + 11.25
B. Answer:2 .25 Tons
Step-by-step explanation:
Weight of truck + sand when filled= 18 tons
Discharge rate per minute= 1/8 tons/ minute
Quantity of sand in the truck will be:
1/8tons per minute×18tons = 9/4 = 2.25tons

What is the volume of a cube that has a side of 4 units?
Answer: 64units³
Step-by-step explanation:
The volume of a cube will be gotten by multiplying the value of its side thrice. This means that for example if the cube has a side of xcm, the volume will be:
= x × x × x
= x³
In this case, since the cube has a side of 4 units, the volume will be:
Volume of cube = 4³
Volume of cube = 4 × 4 × 4 = 64unit³
What is the volume of this shape to the nearest tenth

Suppose that 40% of cars in your area are manufactured in the U.S., 30% in Japan, 10% in Germany, and 20% in other
countries. Determine the following probabilities.
a. a car selected at random is made in Germany or Japan
b. a car selected at random is not US-made
c. two cars are selected at random, both are from Japan
Complete your work in the space provided or upload a file that can display math symbols if your work requires it. Include
your calculations in your answer.
Answer:
A) The probability that a randomly chosen car is made in Germany or Japan is 40%.
B) The probability that a car chosen at random is not made in the United States is 60%.
C) The probability that two randomly chosen cars are both from Japan is 9%.
Step-by-step explanation:
Supposing that 40% of cars in my area are manufactured in the US, 30% in Japan, 10% in Germany, and 20% in other countries, to determine the probabilities that a car selected at random is made in Germany or Japan, a car selected at random is not US-made and two cars are selected at random, both are from Japan, the following calculations must be performed:
A)
(30 + 10) / 100 = X
40/100 = X
0.4 = X
Therefore, the probability that a randomly chosen car is made in Germany or Japan is 40%.
B)
(30 + 10 + 20) / 100 = X
60/100 = X
0.6 = X
Therefore, the probability that a car chosen at random is not made in the United States is 60%.
C)
10/30 x 10/30 = X
0.3 x 0.3 = X
0.09 = X
Therefore, the probability that two randomly chosen cars are both from Japan is 9%.

Submit Question
9514 1404 393
Answer:
A) a + s = 297
B) 30a +20s = 6050
C) 286 students
D) 11 adults
Step-by-step explanation:
A) Total people is the sum of the numbers of adults and students:
a + s = 297
__
B) Total revenue is the sum of revenue from each class of attendees:
30a +20s = 6050
The solution is ...
30a + 20(297 -a) = 6050 . . . there were 297-a students
10a = 110 . . . . . . . . . . . . . . . . subtract 5940
a = 11
s = 297 -11 = 286
__
C) 286 students attended.
__
D) 11 adults attended.

Consider the right triangle with hypotenuse 5, horizontal leg x , vertical leg y , and angle ∅ opposite y. How can we view x as depending on y? How can we view x as depending on ∅ ? Explain by using appropriate relationships in the triangle and writing x both as a function of y and as a function of ∅ .
9514 1404 393
Answer:
x = √(25 -y²)x = 5cos(Ф)Step-by-step explanation:
The Pythagorean theorem relates the sides of a right triangle.
x² + y² = 5²
x² = 25 -y²
x = √(25 -y²)
__
The cosine function relates the adjacent side and the hypotenuse of an acute angle in a right triangle.
Cos = Adjacent/Hypotenuse
Adjacent = Hypotenuse × Cos
x = 5·cos(Ф)

Trigonometry is the worst please someone answer this for me ... no links please
Answer: Approximately 22.62 degrees
===============================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(y) = 12/13
y = arccos(12/13)
y = 22.6198649
y = 22.62
Notes:
Arccosine is the same as inverse cosine. On your calculator there should be a button labeled [tex]\cos^{-1}[/tex]Make sure your calculator is in degree modeThe decimal result for y, shown above, is approximate. I rounded to two decimal places to show the final answer. Round however you need to if your teacher instructs otherwise.A tortoise crawling at a rate of 0.1 mi/h passes a resting hare. The hare wants to rest another 30 min
before chasing the tortoise at the rate of 5 mi/h. How many feet must the hare run to catch the tortoise?
Answer:
The rabbit will run 264feet to get to the tortoise
Step-by-step explanation:
To solve this problem perfectly, we need to take note of the units and conversions involved.
The speed of the tortoise is 0.1 mi/hr
The speed of the hare is 5mi/hr
If the hare rests for another 30 minutes before he starts running the race, We are to get the distance covered by the tortoise under this 30 minutes.
The tortoise runs 0.1 miles in 1 hour
The tortoise will run x miles in 0.5 hours.
x = 0.5 X 0.1 = 0.05 miles.
Therefore, the distance covered by the Tortoise within 30 minutes is 0.05 miles.
The hare will have to run for 0.05 miles before he can catch up to the tortoise.
It is now unit conversion comes into play. We are converting the 0.05 miles to feet so we can get our final answer.
The answer in feet is 264 feet.
Therefore, the rabbit will run 264feet to get to the tortoise
Which table shows a proportional relationship?
Answer:
Table D (the last option)
Step-by-step explanation:
The table that shows a proportional relationship between x and y is the table where the value of y/x for all pair of values on the table are the same and equal.
k = y/x
Thus, in table D,
-8/1 = -24/3 = -32/4 = -48/6 = -8
This shows that the table represents a proportional relationship.
