Express the formula V=l x w x h in terms of the width, w. Use your formula to find the width when the volume is 192, the length is 8, and the height is 4
Answer:
6
Step-by-step explanation:
192=8*4*w
make w subject to formula
w=192/32
w=6
The expression of width is w = V/(l*h) and the value of width is 6.
What is substitution of equation to find the expression of width ?Given formula of volume is V = l * w * h .
Substituting width (w) from the above equation,
w = V/(l*h) .
Finding the value of width from the expression -Given expression after substitution is w = V/(l*h) .
⇒ w = 192/(8 * 4)
∴ w = 6 .
Thus the value of width is 6.
Therefore, the expression of width is w = V/(l*h) and the value of width is 6.

Suppose a certain manufacturer deposits $7,000 at the beginning of each 3 month period for 8 years in an account paying 8% interest compounded quarterly.
Required:
a. How much (in $) will be in the account at the end of the 6 year period?
b. What is the total amount (in $) of interest earned in this account?
9514 1404 393
Answer:
a) $217,212.10 after 6 years
b) $91,780.99 interest earned
Step-by-step explanation:
The future value of this "annuity due" can be found using the formula ...
FV = P(1 +n/r)((1 +r/n)^(nt) -1)
where P is the periodic payment made n times per year and r is the annual interest rate.
a) After 6 years, the value of the account is ...
FV = $7000(1 +4/0.08)((1 +0.08/4)^(4·6) -1) = $217,212.10 . . . . 6-yr balance
__
b) After 8 years, the value in the account is ...
FV = $7000(51)(1.02^32 -1) = $315,780.99
The total of payments is $7000×32 = $224,000, so the interest earned is ...
I = $315,780.99 -224,000 = $91,780.99 . . . interest earned
19. Solve 5x^2 - 6x + 1 = 0 using the quadratic formula.
Please give detailed steps!!
Answer:
x = -b ± √b²-4ac /2a
a = 5
b= -6
c= 1
x = -(-6) ± √(-6)² - 4(5)(1) /2(5)
x = 6 ± √36 - 20 / 10
x = 6 ± √16 /10
x = 6 ± 4/10
Breaking into respective signs
x = 6 + 4/10 or 6 - 4/10
x = 10/10 or 2/10
x = 1 or 1/5
x = 1 or 1/5.

Here, you can multiply the second equation by 4 and add the first equation.
4(x -3y) +(-4x +9y) = 4(-6) +(9)
-3y = -15 . . . . . . . . . . simplify
y = 5 . . . . . . . . . . . . divide by -3
x -3(5) = -6
x = -6 +15 = 9
The solution is (x, y) = (9, 5).

30=26-a/6
Solve for a
Answer:
the answer is 24
Step-by-step explanation:
30=26-a\6
collect like terms
30-26 =a\6
4=a\6
Cross multiply
a=4×6
a=24
The solution to the given equation is 24.
The given equation is 30 = 26-a/6.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 30 = 26-a/6
Transpose 26 to the other side of the equation, we get
30-26 = -a/6
-4 = -a/6
4 = a/6
Transpose 6 to the other side of the equation, we get
a = 4×6
a = 24
So, the solution is 24.
Therefore, the solution to the given equation is 24.

Select all transformations that carry rectangle
ABCD onto itself.
A. Rotate by 90 degrees clockwise using center P.
B. Rotate by 180 degrees clockwise using center P.
C. Reflect across line m.
D. Reflect across diagonal AC.
E. Translate by the directed line segment from A to B.
Answer:
I got B and C.
Step-by-step explanation:
When you rotate by 180° you turn it so that it is facing the other way (ie D is B, C is A, etc) since it's a rectangle, when you rotate by 180°, you still have the same rectangle with angles in the same corners. when you reflect across the midpoint, you are just flipping your rectangle over, and so would again have the same effect as turning it 180°.
