Anthony is laying concrete for a driveway. The driveway is to be 24 feet long by 11 feet wide by 8 inches deep. Answer parts (a) through (c)
(a) Determine the volume of concrete needed in cubic feet.
(b) If 1 cubic yard = 27 cubic feet, how many cubic yards of concrete are needed?
(c) If the concrete costs $36 per cubic yard, what is the cost of the concrete? Concrete must be purchased in whole cubic yards
Answer:
a) The volume of concrete needed in cubic feet is 2,112. b) The number of cubic yards of concrete needed in cubic yards is about 79. c) The cost of the concrete using cubic yards is $2,844.
Step-by-step explanation:
a) The formula of the volume is l*w*d. 24 * 11 * 8 = 264 * 8 = 2,112.
b) The way to find this is that you take 2,112 and divide it by 27. Since the answer is 78.2 repeating, you round it up to 79 so it will fill up all of the concrete.
c) Since you need 79 cubic yards of concrete, you do 79 multiplied by $36 to get the total cost of $2,844.

At 3:30 p.m., Berto’s train was 34 miles past the egg farm, traveling at an average speed of 85 miles per hour. At the same time on a nearby track, Eduardo’s train was traveling at an average speed of 110 miles per hour and had 12 miles to go before it reached the egg farm. To the nearest hundredth of an hour, after how much time will the trains meet up?
E=egg farm
x=distantce between the Berto´s trains and the meeting point.
t=time where the trains meet up
⇒110 miles/h ⇒85miles/h
[---------------------------E----------------------]-------------------------------------X
[............12 miles.......][........34 miles.....][------------ x ----------------------]
distance between Berto´s train and Eduardo´s train=
=12 miles+34 miles=46 miles.
S=d/t ⇒d=S*t
S=seed
d=distance
T=time
Eduardo´s train;
46 miles+x=t*110 miles/h ⇒x=t*110 miles/h-46 miles (1)
Berto´s train;
x=t*85 miles/h (2)
With the equations (1) and (2) we suggest this system equations:
x=t* 110 miles/h-46 miles
x=t*85 miles/h
we solve this system equiations :
t*110 miles/h-46 miles=t*85 miles/h
110t miles/h-85t miles/h=46 miles
25 t miles/h=46 miles
t=46 miles/25 miles/h=1,84 hour (≈1 hour, 50 minutes, 24 seconds)
x=t*85 miles/h=156,4 miles
Solution: 1,84 hour

A student has a range of values from 0.000001 to 1,000,000, but limited paper to graph these values on. How might the student be able to graph these results clearly?
Answer:
logarithmic scale
The student might be able to graph these results clearly by taking the log of the values.
What is logarithm of a number?"Logarithms are the inverse of exponents. ""x is the logarithm of n to the base b if [tex]b^x=n[/tex]"For given question,
A student has a range of values from 0.000001 to 1,000,000
We need to find the way so that the student will be able to graph these results.
We can write 0.000001 as [tex]1\times 10^{-6}[/tex]
[tex]\Rightarrow 0.000001=10^{-6}[/tex]
and 1,000,000 as [tex]1\times 10^6[/tex]
[tex]\Rightarrow 1,000,000=10^6[/tex]
If we take the log of these range values, then it would be,

and [tex]log(10^6)=6[/tex]
This means, the student might be able to graph these results clearly by taking the log of the values.

Find 3 consecutive integers such that the sum of all 3 integers is equal to 4 times the smallest integer minus 9. Please help I need it asap I will appreciate it a lotttt
Answer:
The three integers are 12,13 and 14
Step-by-step explanation:
Let
x,x+1,x+2 be three consecutive integers.
Out of these, the smallest one is x and largest is x+2 as it comes at last in the integers.
So according to given statement
[tex]x+(x+1)+(x+2) = 4x-9[/tex]
This is a linear equation in one variable, which can simply be solved by using equality properties
[tex]x+x+1+x+2 = 4x-9\\3x+3 = 4x-9[/tex]
Subtracting 4x from both sides
[tex]3x+3-4x = 4x-9-4x\\-x+3=-9[/tex]
Subtracting 3 from both sides
[tex]-x+3-3 = -9-3\\-x = -12\\x = 12[/tex]
The smallest integer is 12.
The other integers are:
x+1 = 12+1 = 13
x+2 = 12+2 = 14
Hence,
The three integers are 12,13 and 14

Points (-2, 3) and (x, 0) have a slope of 1/5.Find the x coordinate of the point.
Answer:
x = -17
Step-by-step explanation:
y - y1 = m(x - x1)
y - 3 = 1/5(x - (-2))
y - 3 = 1/5(x + 2)
y - 3 = 1/5x + 0.4
y = 1/5x + 0.4 + 3
y = 1/5x + 3.4
Now we plug in y as 0 to find x
y = 1/5x + 3.4
(0) = 1/5x + 3.4
-3.4 = 1/5x + 3.4 - 3.4
-3.4 = 1/5x times 5
-3.4 times 5 = x
-17 = x
Answer:
x = -17 (Verified Answer) ✅Step-by-step explanation:
If we know the slope, we can solve for an unknown coordinate. First, let's review how to calculate slope.
Slope = Rise/Run (Change in y/Change in x)
In this case, we know the slope, so we will write out the slope formula. We will use the substitution method to solve this.
m = rise/run
rise = y2- y1 substituting ----> 3 - 0 = 3
run = x2 - x1 substituting ----> -2 - x = run
Now, we can return to the slope formula, as we now have enough information to solve.
1/5 = 3/R
To solve, we simply need to find the equivalent fraction of 1/5. We will use a proportion.
1R = 5 x 3
R = 15
Now that we know R, we can substitute it into the equation for run.
So, we now have:
15 = -2 - x
Subtracting -2 from both sides, gives us x = -17.
Finally, we must check our answer to make sure we are getting the correct slope when we calculate.
m = (3 - 0)/(-2 - -17)
m = 3/15 OR 1/5
Since. this matches the original slope we were given, we can be sure the answer is correct.

84 y is directly proportional to x. Given that y = 144 and x = 12. Find the value of y when x = 7.
find the slope and the y-intercept of 7x = 2y-4
Answer:
Slope: [tex]\frac{7}{2}[/tex]
Y-intercept: (0, 2)
Step-by-step explanation:
7x = 2y - 4
-2y = -7x - 4
y = [tex]\frac{-7}{-2}[/tex] x - [tex]\frac{4}{-2}[/tex]
y = [tex]\frac{7}{2}[/tex] x + 2
The slope is always the coefficient of x and the y-intercept is always the constant. It looks like (0, constant) when written in y-int form.
Answer:
slope (m) is 7/2 (aka 3.5) and y-int is (0,2)
Step-by-step explanation:
I don't really have an explanation, basically rearrange the problem so that to y is on the left but it would be 2y so divide the right side by two. I an explain further in depth if needed
