Answer: 84 cubes
Step-by-step explanation: Given, The dimension of the rectangular prism are, 1 1/3 ft. * 1 * 2 1/3 = 4/3 * 7/3 = 28/9 cube ft.
Now, the volume of a cube = side³, if side = 1/3 ft., Then the volume of each cube, V = (1/3)³ = 1/27 cube ft.
Hence, the number of cubes that can be packet in the prism = V/V1 = 28/9 / 1/27 = 27*28/9 = 3 * 28 = 84
A) The number of small cubes which can be packed in the rectangular prism are 180.
B) The volume of the rectangular prism in terms of the small cube and a unit cube will be 180 units³
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
Length = 2 1/4 feet
Width = 1 feet
Height = 1 1/4 feet
And, The lengths of the sides of a small cube are 1 /4 foot each.
Now,
Since, The volume of rectangular prism = Length x width x height
Substitute all the values, we get;
⇒ The volume of rectangular prism = 2 1/4 × 1 × 1 1/4
= 9/4 × 1 × 5/4
= 45/16 ft³
= 2.81 ft³
And, The Volume of one cube = Side³
Here, The length of side of cube = 1/4 feet = 0.25 feet
Hence, The Volume of one cube = Side³
The Volume of one cube = 0.25³
The Volume of one cube = 0.015625 ft³
So, The number of small cubes that can be packed in the rectangular prism = Volume of rectangular prism / Volume of cube
= 2.81 /0.015625
= 180
B) The length, the width and the height of the rectangular prism in term of units cubes is:
Length = 2 1/4 feet / 0.25 feet = 2.25 / 0.25 = 9 units
Width = 1 feet / 0.25 feet = 4 units
Height = 1 1/4 feet / 0.25 feet = 1.25 / 0.25 = 5 units
So, The volume of the rectangular prism in terms of the small cube and a unit cube is,
Volume = 9 x 4 x 5
= 180 units³

You have 2 different savings accounts. For Account A, the simple interest earned after 21 months is $5.95. For Account B, the simple interest earned after 30 months is $36.00. If the interest rate is %3.4 for Account A and %2.4 for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
Answer: Principal amount is A = $250.09
Principal amount is B = $400.
Account B earned you the most interest the first month
The formula for simple interest is expressed as
I = PRT/100
Where
P = the principal or initial amount of money invested.
R = interest rate
T = time
On account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years.
Using the formula:
On account B,
I = $13.80
R = 2.3%
T = 18 months = 18/12 = 1.5 years
Using the formula:
To determine the account that earned more interest in the first month we divide the interest by the number of months.
$6.94/9 = $0.7711
$13.80/18 = $0.7667
Account B earned you the most interest the first month because $0.7667 is higher than $0.7711.

A sporting goods store is having a sale in which all sleeping bags are discounted by 20%. Priya has a coupon for $5 off the regular price of a sleeping bag. The store first applies this coupon and then takes 20% off the reduced price. If Priya pays $34.40 for the sleeping bag, what was the original price, x, before the sale and without the coupon?
the original price was "x", which oddly enough is the 100%.
now, let's pluck out of "x" 5 bucks, so that makes it "x-5", that's our new adjusted 100%, from which the lady at the counter is happy to apply a 20% discount. Now, if the lady discounts 20% off of that "x-5" amount, what Priya is really paying for the sleeping bag is just 100% - 20% = 80%, and we happen to know that that 80% was really $34.40.
now, if "x - 5" is the 100%, and we know that 34.40 is the 80%, what the heck is "x"?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x-5 & 100\\ 34.40& 80 \end{array} \implies \cfrac{x-5}{34.40}~~=~~\cfrac{100}{80} \implies \cfrac{ x-5 }{ 34.40 } ~~=~~ \cfrac{ 5 }{ 4 } \\\\\\ 4x-20=172\implies 4x=192\implies x=\cfrac{192}{4}\implies x=48[/tex]

In the triangle ABC, AB = (x + 3)cm, BC = (x + 2)cm, AC = x cm and angle BAC = 60degrees
Find the value of x.
Answer:
x = 5---------------------------------
Side BC is opposite to ∠BAC and adjacent sides are AB and AC.
Use the law of cosines:
BC² = AB² + AC² - 2AB*AC*cos ∠BAC
Substitute and solve for x:
(x + 2)² = (x + 3)² + x² - 2x(x + 3) cos 60°x² + 4x + 4 = x² + 6x + 9 + x² - 2(x² + 3x)*1/2x² + 4x + 4 = 2x² + 6x + 9 - x² - 3xx² + 4x + 4 = x² + 3x + 94x - 3x = 9 - 4x = 5Which expression has like terms?

Answer: The difference between the angle measure is 152 degrees
Step-by-step explanation: Supplementary angles are angles that add up to 180
So if one angle is x in this case, the other will be 14x
Adding both ;
x + 14x = 180
15x = 180
x = 180/15
x = 12
The other angle is 14 * 12 = 168
The difference between the two will be;
168-12 = 156
Answer:
168
Step-by-step explanation:
m<B + m<C = 180 since the angles are supplementary.
m<B = 14m<C since the measure of angle B is 14 times the measure of angle C.
m<B + m<C = 180
14m<C + m<C = 180
15m<C = 180
m<C = 180/15
m<C = 12
m<B = 14m<C = 14 × 12
m<B = 168
Answer: 168

3 groups are shown. Each group shows 2 tens rods and 6 ones cubes.
Which division problem is shown by the model?
A. 0.66÷3=0.22
B. 0.66÷3=0.26
C. 0.78÷3=0.62
D. 0.78÷3=0.26
Answer:
D
Step-by-step explanation:
well, it all starts with a check, what calculations in the answer options are even correct.
A. is correct. 0.66/3 = 0.22
B. is incorrect
C. is incorrect
D. is correct. 0.78/3 = 0.26
so is it A or B ?
one group of 2 tens and 6 ones : how much is that ?
2×10 + 6×1 = 20 + 6 = 26
3 groups of 26 means
3×26 = 78
so, the combination of the 3 groups would either show that
3×26 = 78
or
78/3 = 26
and that is the same as showing
0.78/3 = 0.26
because
0.78 = 78/100
0.26 = 26/100
therefore
78/100 / 3 = 26/100
78/100 = 3×26/100 = 78/100
correct.

Given:
A = $5,000P = $4,000r = 5% = 0.05Substitute the given values into the formula and solve for t:
[tex]\implies 5000=4000(1+0.05t)[/tex]
[tex]\implies \dfrac{5000}{4000}=1+0.05t[/tex]
[tex]\implies1.25=1+0.05t[/tex]
[tex]\implies 0.05t=1.25-1[/tex]
[tex]\implies 0.05t=0.25[/tex]
[tex]\implies t=\dfrac{0.25}{0.05}[/tex]
[tex]\implies t=5\; \rm years=60\; months[/tex]
Given:

[tex]\implies 11160=P(1+0.08 \cdot 3)[/tex]
[tex]\implies 11160=P(1.24)[/tex]
[tex]\implies P=\dfrac{11160}{1.24}[/tex]
[tex]\implies P=\$9000[/tex]
Given:
A = $3,207P = $3,000t = 18 months = 1.5 yearsSubstitute the given values into the formula and solve for r:
[tex]\implies 3207=3000(1+r \cdot 1.5)[/tex]
[tex]\implies \dfrac{3207}{3000}=1+1.5r[/tex]
[tex]\implies 1.069=1+1.5r[/tex]
[tex]\implies 1.5r=1.069-1[/tex]

A circle’s circumference is 600 m.
What is a good approximation of the circle’s area? 1. 300\ m^{2} 2. 3,000\ m^{2} 3. 30,000\ m^{2} 4. 300,000\ m^{2}
The area of the circle is approximately 30,000 [tex]m^{2}[/tex]
The circumference of the circle is given as 600m.
And we know that circumference = [tex]2\pi r[/tex] where r is the radius of the circle.
Therefore,
[tex]2\pi r = 600[/tex]
[tex]r = \frac{600}{2\pi }[/tex]
[tex]r = \frac{300}{\pi }[/tex]
Now, we know that area of the circle = [tex]\pi r^{2}[/tex]
Putting the value of r in this, we get
area = [tex]\pi (\frac{300}{\pi } )^{2}[/tex]
area = [tex]\pi.\frac{300}{\pi } .\frac{300}{\pi }[/tex]
Therefore, area of the circle = 28,647.889 [tex]m^{2}[/tex]
Therefore, the correct answer is 30,000 [tex]m^{2}[/tex]
