The figure below is a net for a right rectangular prism. Its surface area is 432 m2 andthe area of some of the faces are filled in below. Find the area of the missing faces,and the missing dimension.
The surface area is the sum of all the areas in the given prims, then we have:
[tex]SA=72+72+48+48+2A[/tex]Plugging the value for the surface area and silving for A we have:
[tex]\begin{gathered} 432=72+72+48+48+2A \\ 432=240+2A \\ 2A=432-240 \\ 2A=192 \\ A=\frac{192}{2} \\ A=96 \end{gathered}[/tex]Now that we know the missing area we can know the missing dimension:
[tex]\begin{gathered} 96=8x \\ x=\frac{96}{8} \\ x=12 \end{gathered}[/tex]Therefore the missing length is 12.
distance is a direct variation of time if the distance
Explanation
In order to be able to predict the time, it will take to cover 220 miles, we will have to get the relationship
The relationship between distance and the time can be obtained as follow:
When the distance is 80 miles, the time taken is 2 hours
So when the distance is 220 miles, the time taken will be
[tex]x=\frac{220\times2}{80}=5.5[/tex]Therefore, it will take 5.5 hours to cover a distance of 220 miles
Therefore, the answer is 5.5 hours

If your car gets 32 miles per gallon, how much does it cost you to drive 30 miles when gasoline costs $2.55 per gallon?
32 miles ---------> 1 gallon
30 miles--------------> xgallons
Solving for x:
32/30 = 1/x
x = 30/32 = 0.9375 gallons
1 gallon ------>$2.55
0.9375 gallons----->$y
1/0.9375 = 2.55/y
Solving for y:
y = 2.55*0.9375 = $2.390625
It will cost $2.390625
A couple plans to save for their child's college education. What principal must be deposited by the parents when their child is born in order to have $37,000 when the child reaches the age of 18? Assume the money earns 9% interest, compounded quarterly. (Round your answer to two decimal places.)
We can use the compound interest formula:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]Where:
A = Amount = $37000
P = Principal
r = Interest rate = 9% = 0.09
n = Number of times interest is compounded per unit of time = 4 (Since it is compounded quarterly)
t = time = 18
Therefore:
[tex]37000=P(1+\frac{0.09}{4})^{18*4}[/tex]Solve for P:

Factor 3x² + 10x + 8 using earmuff method.
To factor the above quadratic equation using Earmuff Method, here are the steps:
1. Multiply the numerical coefficient of the degree 2 with the constant term.
[tex]3\times8=24[/tex]2. Find the factors of 24 that when added will result to the middle term 10.
1 and 24 = 25
2 and 12 = 14
3 and 8 = 11
6 and 4 = 10
Upon going over the factors, we will find that 6 and 4 are factors of 24 and results to 10 when added.
3. Add "x" on the factors 6 and 4. We will get 6x and 4x.
4. Replace 10x in the original equation with 6x and 4x.
[tex]3x^2+6x+4x+8[/tex]5. Separate the equation into two groups.
[tex](3x^2+6x)+(4x+8)[/tex]6. Factor each group.
[tex]3x(x+2)+4(x+2)_{}[/tex]7. Since (x + 2) is a common factor, we can rewrite the equation into:
[tex](3x+4)(x+2)[/tex]Hence, the factors of the quadratic equation are (3x + 4) and (x + 2).
Another way of factoring quadratic equation is what we call Slide and Divide Method. Here are the steps.
[tex]3x^2+10x+8[/tex]1. Slide the numerical coefficient of the degree 2 to the constant term by multiplying them. The equation becomes:
[tex]\begin{gathered} 3\times8=24 \\ x^2+10x+24 \end{gathered}[/tex]2. Find the factors of 24 that results to 10 when added. In the previous method, we already found out that 6 and 4 are factors of 24 that results to 10 upon adding. So, we can say that the factors of the new equation we got in step 1 is:
[tex](x+6)(x+4)[/tex]3. Since we slide "3" to the constant term, divide the factors 6 and 4 by 3.
[tex]\begin{gathered} =(x+\frac{6}{3})(x+\frac{4}{3}) \\ =(x+2)(x+\frac{4}{3}) \end{gathered}[/tex]4. Since we can't have a fraction as a factor, slide back the denominator 3 to the term x in the same factor.
[tex](x+2)(3x+4)_{}[/tex]Similarly, we got the same factors of the given quadratic equation and these are (x + 2) and (3x + 4).

ANSWER:
33.5%
STEP-BY-STEP EXPLANATION:
We have the amount in 2003 in 5799 fish and in 2014 there are there are 1943 less fish.
The percentage of change would be the difference in fish between these years divided by the initial amount of fish, just like this:
[tex]\begin{gathered} p=\frac{5799-(5799-1943)}{5799}\cdot100 \\ \\ p=\:\frac{1943}{5799}\cdot100\: \\ \\ p=33.505\cong33.5\% \end{gathered}[/tex]This means that the percentage of change is negative since the population has decreased by 33.5%.
c) How would you describe the correlation in the data? Explain your reasoning.

I'm reviewing for a final. Can u please help me solve the following
The direction of the resultant vector is approximately 320°.
We have three vectors. The magnitudes of the vectors t, u, and v are 7, 10, and 15, respectively. The angles of the vectors t, u, and v are 240°, 30°, and 310°, respectively. We have to find the angle of the resultant vector of the sum of all three vectors. To add all the three vectors, we need to split the vectors into their horizontal and vertical components. The horizontal components are 7cos(240°), 10cos(30°), and 15cos(310°). The vertical components are 7sin(240°), 10sin(30°), and 15sin(310°).
Let the horizontal and vertical components of the resultant vector be denoted by H and V, respectively. The horizontal component is H = 7cos(240°) + 10cos(30°) + 15cos(310°) = 7*(-0.5) + 10*(0.866) + 15*(0.643) = -3.5 + 8.66 + 9.645 = 14.805. The vertical component is V = 7sin(240°) + 10sin(30°) + 15sin(310°) = 7*(-0.866) + 10*(0.5) + 15*(-0.766) = -6.062 + 5 - 11.49 = -12.552. The angle of the resultant vector can be calculated by the ratio of the components as tan(θ) = V/H = -12.552/14.805 = -0.848. So, the angle "θ" is approximately equal to 320°.

bruce will charge the customer $23.75
Explanation:
Amount charged per pound = $4.75
Let the number of pounds of produce = x
Total cost per number of pounds = $4.75 × x
Let the total cost of produce = y

For the long-distance service, David pays a monthly fee of $7 plus 7 cents per minute.
Let "d" represent the minutes the call lasted, and "c" the total cost of the bill, then you can express the total cost of the bill using the following expression:
[tex]c=7+0.07d[/tex]If the total cost of the bill was c=13.93, to determine the number of minutes David was billed for, you have to replace input this value in the equation and solve it for d
[tex]\begin{gathered} c=7+0.07d \\ 13.93=7+0.07d \end{gathered}[/tex]Pass 7 to the other side of the equation by applying the opposite operation

Steve made a business trip of 200.5 miles. He averaged 51 mph for the first part of the trip and 62 mph for the second part. If the trip took 3.5 hours, how long did hetravel at each rate?
Let t = time traveled at 51 mph
The total time is given as 3.5 hours
So (3.5- t )= time traveled at 62 mph
We are going to use the distance formula:
distance = speed* time
51t + 62(3.5-t) = 200.5
51t + 62*3.5 - 62*t = 200.5
51t + 217 - 62t = 200.5
Solve the equal terms
51t - 62t = 200.5 - 217
-11t = -16.5
t = -16.5/-11
t = 1.5
Then he took 1.5 at 51mph
and (3.5- t ) = (3.5-1.5) = 2h at 62 mph
To confirm these results, find the actual speed of each speed:
speed* time = distance
51*1.5 = 76.5miles
62*2. = 124 miles
76.5miles + 124 miles = 200.5miles
