Solution:-Since painting is done on outer surface of cubical block we will have to find its surface area which is given by-
[tex]\green{ \underline { \boxed{ \sf{Surface \: area \:of \:Cube = 6a^2}}}}[/tex]
where a is side of the cube[tex]\begin{gathered}\\\quad \sf Surface \: area \:of \:Cube = 6\times(3.2)^2 \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies \quad \sf 6\times 3.2\times3.2 \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies \quad \sf 61.44 cm^2 \\\end{gathered} [/tex]
Now,
[tex]\maltese \sf Cost \:of \:painting \: 1 \: cm² = \$ 5[/tex]
[tex] \sf Cost \: of \: painting \: 61.44 \:cm²=61.44×5[/tex]
[tex]\sf\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad=\$ 307.2[/tex]
[tex]\leadsto[/tex]Thus it would cost $ 307.2 to paint the entire cubical block.

If y varies inversely as x and y is 6 when x is 12, what is x when y is 14. 4? a. 5 b. 0. 4 c. 9. 6 d. 2. 5.
The value of x when y is 14.4 is 5.
It is given that
y ∝ 1/x
y = k/x....(1)
Where k is a constant of proportionality
What is the constant of proportionality?The constant of proportionality is the ratio that relates two given values.
When y =6, x=12
Means, 6 = k/12
k = 72
Putting the value of k in equation (1)
y = 72/ x
14.4 = 72/ x
x = 5
Therefore, The value of x when y is 14.4 is 5.

65. Find h if 3(2h-1) = 27(-h+2) A) 7 G D) 0
Answer:
A) 7/5
Step-by-step explanation:
An exponential equation like this can be solved by using logarithms, or by rewriting the bases so they are the same.
3^(2h-1) = 27^(-h+2)
Using 27 = 3^3, we can write the equation in terms of powers of 3:
3^(2h-1) = (3^3)^(-h+2)
3^(2h -1) = 3^(-3h +6)
Equating exponents gives ...
2h -1 = -3h +6
5h = 7 . . . . . . . . . add 1+3h
h = 7/5 . . . . . . . divide by 5
__
Additional comment
When solving this using a graphing calculator, it is often convenient to write the equation in such a way that the solution is an x-intercept. Here, we can do that by subtracting the right-side expression from both sides:
3^(2h-1) -27^(-h+2) = 0
The solution is h = 1.4 = 7/5.
Answer:
step by step explanation:h=7/5

Find the measure of ∠WOV. Which angle relationship did you use?
Answer:
Measure of ∠WOV = 60°
Complementary angles
Step-by-step explanation:
The box shows us that is equal to 90°. Angles ∠WOV and ∠WOX are complementary angles because we get 90° when we add them together. Since we are given the measure of ∠WOX we can subtract it from 90° to find the measure of ∠WOV.
90° - 30 ° = 60°

Find the slope of the line that passes through each pair of points (-8, 5) (3, -6)
Answer:
[tex]m=-1[/tex]
Step-by-step explanation:
Given the following question:
Point A = (-8, 5) = (x1, y1)
Point B = (3, -6) = (x2, y2)
To find the answer we have to use the formula to calculate slope or rise over run.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{-6-5}{3--8} =\frac{-11}{11}[/tex]

Answer:
slope: -4/3y-intercept: (0, 4)x-intercept: (3, 0)y = -4/3x +4Step-by-step explanation:
Given two points, the equation for the line through them can be found using the slope formula and the slope-intercept form.
The slope formula is ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-4))/(0 -6) = 8/-6 = -4/3 . . . . slope of the line
The y-intercept is 4, given by the second point.
The slope-intercept equation for a line is ...
y = mx +b . . . . . . line with slope m and y-intercept b
y = -4/3x +4 . . . . . line with slope -4/3 and y-intercept 4
__
The x-intercept can be found by solving for x when y=0.
0 = -4/3x +4
0 = 4x -12 . . . . multiply by -3
0 = x -3 . . . . . . divide by 4
3 = x . . . . . . . . subtract 3
The x-intercept is (3, 0).

The line can be graphed by plotting the given points and drawing the line through them.
Answer:
Slope: [tex]-\frac{4}{3}[/tex]
Y int. : (0,4)
X int. : (3,0)
Step-by-step explanation:
Equations to remember:
[tex]y = mx + b\\\\\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
--------------------------------------------
[tex](x_{1}, y_{1}) = (6, -4)\\\\(x_{2}, y_{2}) = (0,4)[/tex]
--------------------------------------------
SLOPE
You want to set up your equation for finding slope like this:
[tex]\frac{4 - (-4)}{0 - 6}[/tex]
4 - (-4) will become 4 + 4. This is because there is a -1 in front of the parenthesis.
A negative number times a negative number will always equal a positive number.
[tex]-\frac{8}{6}[/tex]
when simplified/divided by 2, which is the number you want:
[tex]-\frac{4}{3}[/tex]
This is your slope or your m in y = mx + b
---------------------------------------------------------------
Y INTERCEPT
Use one of your points.
I'll use (0,4) as an example.
Set up your equation like this:
[tex]4 = -\frac{4}{3}(0) + b[/tex]
Since your slope is being multiplied by ZERO, you can just eliminate your mx or slope.
This means that 4 = b!
That's your Y Int, which you'll find was one of the given points, (0,4).
---------------------------------------------------------------
From there, if you use a graph, you should find that your X Int is (3,0).
I hope this helped you!

What is the value of d?
Answer:
61°
Step-by-step explanation:
The right angle is formed by 29° and an unknown angle. However, we know the unknown angle's value as 61° because 90 - 29 = 61.
The Angle with 61° is congruent to Angle D because they're vertical angles, making d 61°.
A movie theater offers a reward program that charges a yearly membership fee and a discounted rate per movie ticket. The total cost for a reward program member to see 5 movies is $40 and the total cost for 12 movies is $75. Assume the relationship is linear. Write the equation of the function in the form y=mx+b , where x represents the number of movies and y represents the total cost.
Hint: Treat this information like ordered pairs. (5, 40) and (12, 75)
Answer:
[tex]y=5x+15[/tex]
Step-by-step explanation:
Since this situation is a linear relationship between the number of movies and the total cost, we need to determine the slope of the line given our two ordered pairs [tex](x_1,y_1)\rightarrow(5,40)[/tex] and [tex](x_2,y_2)\rightarrow(12,75)[/tex]:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{75-40}{12-5}\\ \\m=\frac{35}{7}\\ \\m=5[/tex]
Thus, our equation so far is [tex]y=5x+b[/tex]. Next, we need to find our y-intercept, [tex]b[/tex], which represents our flat fee. We do so by using one of our original given ordered pairs:
[tex]y=5x+b\\\\40=5(5)+b\\\\40=25+b\\\\15=b[/tex]
Therefore, our final equation for the function is [tex]y=5x+15[/tex]
