Design a closed rectangular box of width w, length l, and height h. The sides of the box cost 1 cent/cm2 and the top and bottom cost 2 cent/cm2 . (a) Write an equation for cost (in cents) in terms of w, l, and h. Use lower case letters.
Answer:
Equation for cost (in cents) in terms of w, l, and h is 2h(w + l) + 4l*w
Step-by-step explanation:
We are given
A rectangular box with dimensions
Width = w
Length = l
Height = h
This needs to be visualized in 3D
First type of Sides of the box is made using the width and height
second type is made using length and height
Area of the 1st two sides = 2*w*h
Area of the 2nd type of sides = 2*l*h
Area of the top and bottom = 2*l*w
Cost for sides = 1cent/cm^2
Cost of the sides calculated = cost* Area= 1*(2*w*h+2*l*h)
= 2h(w + l)
similarly
cost of top and bottom = 2*2*l*w = 4*l*w
Total Cost = 2h(w + l) + 4l*w
After getting 5 new rocks, George gave half of his rock collection to Susan. If George gave Susan 36 rocks, which equation could be used to determine how many rocks George started with?
One-half x = 36 + 5
One-half (x minus 5) = 36
One-half (x + 5) = 36
One-half x + 5 = 36
Answer:
1/2 (x+5) = 36 should be the equation that is used to determine how many rocks George started with.
Step-by-step explanation:
Let 'x' be the number of rocks George had.
As George gave, after getting 5 new rocks, half of his rock collection to Susan which is = 36 rocks
It means after getting 5 new rocks George's total rocks = 72
Given that he gave half collection to Susan = 36
Thus, before inducting 5 new rocks Georg's total rocks were = 67
Thus,
1/2 (x+5) = 36 should be the correct equation.
solving
1/2 (x+5) = 36
Multiplying both sides by 2
1/2 (x+5) × 2 = 36 × 2
x+5 = 72
x = 72 - 5
x = 67
Thus, before getting 5 new rocks, the number of rocks George had = 67
Therefore,
1/2 (x+5) = 36 should be the equation that is used to determine how many rocks George started with.

The cost of 5 hats and 1 scarf is $47. The cost of 2 hats and 2 scarves is $40. How much does one hat cost?
Answer:
6.75
Step-by-step explanation:
h=hat, s=scarf
5h + 1s = $47 (equation 1)
2h + 2s = $40 (equation 2)
multiply equation 1 by 2 , we get: 10h + 2s = $94 (equation 3)
equation 3 minus equation 2, we get:
8h = $54 ⇒ h = $6.75 ⇔ 1 hat cost $6.75
substitute h = $6.75 into equation 2 to find s,
2($6.75) + 2s = $40
$13.5 + 2s = $40
2s = $26.5
s = $13.25 ⇔ 1 scarf cost $13.25

Convert the following quantities as shown.
(a) 24,000 volts to kilovolts
(b) 551 millivolts to volts
So, 24,000 v = how many kv
enter your response as kV - (Type a whole number or a decimal.)
a. 24 Kilovolts
b. 0. 551 Volts
How to convert the quantitiesIt is important to note that;
1000 volts = 1 Kilovolt
1000 millivolts = 1 volt
a. To convert 24,000 volts to kilovolts
If 1000 volts = 1 kilovolt
Then 24000 volts = x
cross multiply
x = 24000/ 1000
x = 24 Kilovolts
b. To convert 551 millivolts to volts
If 1000 millivolts = 1 volt
Then 551 millivolts = x
x = 551/ 1000
x = 0. 551 Volt
Thus, the values are 24 kilovolts and 0. 551 volt respectively

What is meant by square?A square is a subset of a rectangle (an equilateral rectangle) and a subset of a parallelogram (an equilateral and equiangular one).
A square has 4 axes of symmetry and two finite diagonals that are equal (as with any rectangle). A square divided by a diagonal yields two right triangles.As, a wire is 32-centimetre-long,

Answer:
y = 2
Step-by-step explanation:
Slope that passes through two points, (10, y) and (3, 4) = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex].
Where,
[tex] (10, y) = (x_1, y_1) [/tex]
[tex] (3, 4) = (x_2, y_2) [/tex]
m = -²/7
Plug in the values
[tex] \frac{-2}{7} = \frac{4 - y}{3 - 10} [/tex]
[tex] \frac{-2}{7} = \frac{4 - y}{-7} [/tex]
Cross multiply
[tex] -2*-7 = 7(4 - y) [/tex]
[tex] 14 = 28 - 7y [/tex]
[tex] 7y = 28 - 14 [/tex]
[tex] 7y = 14 [/tex]
Divide both sides by 7
y = 2
Two factors are multiplied, and their product is 32.3046. One factor is a whole number. How many decimal places are in the other factor? Tell how you know.
Step-by-step explanation:
a whole number has 0 decimal places (after the decimal point, meaning on the right side of the decimal point).
so, all the decimal places (4) must come from the other factor.
a multiplication by a whole number is always a series of additions of the other factor with itself. if anything, such a multiplication eliminates decimal places. it does not create additional ones.
e.g.
3.06 × 5 = 15.3 (because it is actually 15.30, but trailing 0s don't have any value like leading 0s, and are normally skipped).
the increase in the decimal places happens by involving places with higher value : 1/10 has a higher value than 1/100, that has a higher value than 1/1000, and so on.
so, e.g. 0.2×9 = 1.8 (and not 0.18).
as it is 2/10 × 9 = 18/10 = 1.8
an addition cannot create suddenly new decimal places with lower value.
therefore, normally we would say the other factor has 4 decimal places.
but in reality, it is a I said above, the 4 decimal places of the result of the multiplication "come from the other factor".
we cannot say that the other factor has 4 decimal places, because it could have more, and the multiplication with the whole number removed some.
e.g. 3.6 × 5 = 18 (or 18.0).
so,
32.3046 could be 6.46092 × 5
when we think this through, the other factor could have infinitely many decimal places.
like 5/9 × 108 = 0.555555... × 108 = 60
or our number
32.3046 could be 0.2991166666... × 108
so, all we can say, the other factor must have at least 4 decimal places.
