Answer:The missing dimensions are now
width =7inches
length = 11 inches
Height = 3 inches
Step-by-step explanation:
Volume of a box is given as =width x length x height 231 in^3
Given
width = 7 inches
height =represented as h
l = 8 inches more than the height= 8+h
V = w x l x h
231 = 7(8+h)(h)
231=( h² + 8h)7
231/ 7= h²+8h
33= h²+8h
Giving us the quadratic equation
h² + 8h - 33 = 0
=(h-3)(h+11) = 0
h-3= 0
h= 3 also h+11=0, h=-11
h= 3 or -11
Since the value of height cannot have a negative value,
h = 3inch
l = 8+h = 8+3 = 11 in
The missing dimensions are now
width =7inches
length = 11 inches
Height = 3 inches
The equation below shows the total volume (V), in cubic units, of 4 identical boxes with each side equal to s units: V = 453 If s = 2.5 units, what is the value of V?
Answer:
in cubic units, of 4 identical boxes with each side equal to s units: V = 4s3 If s = 2.5 units, what is the value of V? (5 points) 25 cubic units 30 cubic units 62.50 cubic units 156.25 cubic units

x=±46−−√
Answer:
[tex]\bold{x=-4\pm\sqrt{46}}[/tex]
Step-by-step explanation:
[tex](a+b)^2=a^2+2ab+b^2\\\\\\x^2+8x-30=0\\\\\underbrace{x^2+2\cdot x\cdot 4+4^2}-4^2-30=0\\\\{}\qquad(x+4)^2\,-\,16-30=0\\\\{}\qquad\ \ (x+4)^2=46\\\\ {}\qquad\ \ x+4=\pm\sqrt{46}\\\\ {}\qquad\ \ x=-4\pm\sqrt{46}[/tex]
The solution to the quadratic equation by completing the square will be
x = -4 ± √46. The correct option is A.
What is a quadratic equation?It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The given equation will be solved as below:-
x² + 8x − 30 = 0
Completing the square for the above equation.
( x + 4 )² - 16 - 30 = 0
( x + 4 )² = 46
x + 4 = ±√46
x = ±√46 - 4
Therefore, the solution to the quadratic equation by completing the square will be x = -4 ± √46. The correct option is A.

A sno-cone machine priced at $139 is on sale for 20% off. The sales tax rate is 6.75%. What is the price of the sno-cone machine after the discount and sales tax?
Answer:
$127.03
Step-by-step explanation:
A snow cone machine price at $139 is on after for 20 off.
The price after discount=139-20=$199
The sale tax rate 6.75%
Price with sales tax=199+(6.75%×199)
=199+(0.0675×199)
= 199+8.03
=$127.03

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Properties of indices.
Here, we have to prove that, if the above exponential equation are equal or not., let's prove it
1.)L.H.S
a^12*a^4 = a^m*a^n ===> a^(m+n)
hence, a^(12+4) ===> a^(16)
2.) R.H.S
===> a^8*a^8 = a^(8+8) ==> a^(16)
since here, LHS = RHS
so both are equal.

Height (m) x height (m) =height squared (m exponent 2)
The square of her height in meter² is 2.7225.
How to do decimal multiplication ?To multiply numbers with decimals one way is to multiply the given numbers without the decimal then in the obtained result put the decimal as many places before from the right as the sum of the digits after the digits which those decimal numbers had.
According to the given question Ms. Aluma is 165cm tall.
We know 165 cm is = (165/100)meter = 1.65meter.
As 1 meter is 100 centimeter.
∴ The square of her height is (1.65)² OR (1.65×1.65)m² which is
= 2.7225 m².

There is a 15% discount on all items in a store. You buy a $12 shirt and $45 jeans. What will be your total cost?
Answer:
The total cost of the shirt and Jean's together with a 15% discount would be $48.45.
Step-by-step explanation:
if you at 12 and 45 you get 57 now if you multiply that by .15 which would be 15% you would get $48.45.
Answer:
$48.45
Step-by-step explanation:
15% of $12= 1.80
15% of $45= 6.75
$12-$1.80= $10.2
$45- $6.75= $38.25
Now, add them both up:
$10.20+ $38.25= 48.45

find compound interest on12600rupees for 2years at10% per annum compounded anually
Answer:
₹2520
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 12600 × 0.1 × 2 = 2520
I = ₹ 2,520.00
The simple interest accumulated
on a principal of ₹ 12,600.00
at a rate of 10% per year
