The formula for the volume of a sphere is given below and the relationship between the radius r and the diameter d is r=d/2. Find the EXACT volume of the sphere in terms of the diameter d. Be sure to fully simplify the expression
Answer:
for the volume of the sphere its answer is 4πr³/3 which when converted to diameter will be 2(4πr³/3) as r=diameter/2 so diameter =2r
Answer:
4πr³/3
Step-by-step explanation:
When converted to diameter will be 2(4πr³/3) as r=diameter/2 so diameter =2r

if AB=BA= I then write the relation between matrix A and matrix B
Answer:
If AB = BA = I, then B is inverse of A and vice-versa.
Step-by-step explanation:
Given: AB = BA = I
To find: The relation between matrix A and B.
If AB = BA = I, then B is called the inverse matrix of A and is denoted by [tex]A^{-1}[/tex].
In that case, A is said to be invertible.
Also, if B is the inverse of A, then A is also the inverse of B.
Hence, the relation between A and B is that both are inverse of each other.

12) Two rectangles are similar. The length of small rectangle is 4 and the length of the big
rectangle is 12. If the perimeter of the smaller rectangle is 28, then what is the perimeter
of the larger rectangle
Answer:
84
Step-by-step explanation:
To get from 4 to 12, you multiply with 3.
Everything is 3 times as big in the larger rectangle.
This includes the perimeter.
Example:
small rect 4x10, perimeter 4+4+10+10 = 28
large rect 12x30, perimeter 12+12+30+30 = 84
but also 28x3 = 84
The perimeter of the larger rectangle is 84.
What is perimeter?Its the sum of length of the sides used to made the given figure.
We are given that length of small rectangle is 4 and the length of the big
rectangle is 12. If the perimeter of the smaller rectangle is 28,
The small rectangle
length = 4
perimeter = 28
The big rectangle
length = 12
perimeter = ?
The small rectangle perimeter = 2l + 2w
28 = 2 * 4 + 2 w
28 - 8 = 2w
20 / 2 = w
10 = w
The big rectangle perimeter;
4 w = 10 * 12
w = 120 / 4 = 30
Perimeter = 2*12 + 2*30
= 24 + 60 = 84
The perimeter of the big rectangle is 84.

Duncan and his family are season ticket holders for their favorite baseball team. Last year, the cost of season tickets was $2,730. This year, the cost is $3,333.80. What was the percent of increase in the cost of season tickets?
Round your answer to the nearest tenth of a percent.
Answer:
10%
Step-by-step explanation:
To find the answer we need to know what percentage of $1030 is $927 and to do this we can multiply 927 by 100 and divide by 1030.
(927(100))/1030
92700/1030
90
so now that we know $927 is 90% of $1030 we can subtract 90 from 100 and it'll give us the percentage decrease. Which is 10%.

What is the approximate volume of the cylinder?Use 3.14 for Pie
A)904.32cm_3
B)226.08cm_3
C)301.44cm_3
D)150.72cm_3
Answer:
The volume of cylinder: r squared times pi times height= 1.2 times 1.2 times pi times 20 = 1.44 times pi times 20 which is around 90.48 meters squared. Volume of water: r squared times pi times height = 1.2 times 1.2 times pi times 1 = 1.44 times pi which is around 4.52 meters squared.
The volume of the cylinder is 904.32 cubic cm if the radius is 6 cm and height of the cylinder is 8 cm option (A) is correct.
What is a cylinder?In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2 h[/tex]
Here r = 6 cm
h = 8 cm
π = 3.14
The volume of the cylinder:
[tex]\rm V = 3.14 \times(6)^2 \times 8[/tex]
V = 904.32 cubic cm
Thus, the volume of the cylinder is 904.32 cubic cm if the radius is 6 cm and height of the cylinder is 8 cm option (A) is correct.

Every rational number is an integer.
True
False
======================================================
Explanation:
A counter-example could be something like 2/3 which is rational, but not an integer since 2/3 = 0.67 has a fractional or decimal portion to it. An integer is one where its a positive or negative whole number. Zero is also an integer.
Any rational number is a ratio or fraction of two integers. Zero is not allowed in the denominator. Any integer is a rational number since x = x/1, where x is any integer. For example, 9 = 9/1.
Answer:
False
Step-by-step explanation:
Rational numbers include all integers, fractions, or terminating and repeating decimals.

Harriet used her credit card to buy a $779 laptop, which she paid off by making identical monthly payments for two and a half years. Over the six years that she kept the laptop, it cost her an average of $0.36 of electricity per day. Harriet’s credit card has an APR of 11.27%, compounded monthly, and she made no other purchases with her credit card until she had paid off the laptop. What percentage of the lifetime cost of the laptop was interest? (Assume that there were two leap years over the period that Harriet kept the laptop, and round all dollar values to the nearest cent.)
a.
7.03%
b.
13.21%
c.
11.27%
d.
6.97%
Answer:
7.03%
Step-by-step explanation:
The percentage of the life time cost which was the interest is; Choice B; 13.21%
Percentage and InterestSince, the APR is compounded monthly at an Annual percentage rate, APR of 11.27%, it follows that;
A = 779(1+0.1127)^(2.5)Hence, the total amount to be paid over the two and half years is; A = $1017.38.
Hence, the interest is given as;
Interest = $1017.38 - $779 = $238.38.The cost of electricity bill at $0.36 per day, (Assuming that there were two leap years over the period).
Cost = 0.36((4×365) +(2×366))Cost = $789.12Hence, the lifetime cost of the laptop is; $789.12 + $1017.38 = $1806.5.
Ultimately, the required percentage is;
($238.38/$1806.5) × 100% = 13.21%Read more on percentages and interest;
