To find how many 1/3 cm length cubes fill the prism, we first need to find the volume, which is equal to
length * width * height = 1 cm * (2 + 2/3) cm * (2/3) cm
= 1 cm * (6/3 + 2/3) cm * (2/3) cm
= 1 cm * (8/3) cm * (2/3) cm
= (8/3) cm ² * (2/3) cm
= (16/9) cm³
Therefore, the volume is 16/9 cm³.
Next, one cube with side lengths of 1/3 has a volume of ((1/3) cm)³ = (1/27)³
We thus need to find how many of 1/27 goes into 16/9
If we multiply 16/9 by 1=3/3 (as 9*3=27), we can equalize the bases, making 16/9 = 48/27
All that's left is to figure out how many times 1/27 goes into 48/27, which is equal to (48/27)/(1/27) = 48
Arianna is buying plants for her garden. She buys 15 flowering plants for $96. Pink flowering plants sell for $8, and purple
flowering plants sell for $5. How many pink flowering plants did Arianna buy?
Answer:
Arianna bought 7 pink flowering plants.
Step-by-step explanation:
Variable x = number of pink plants
Variable y = number of purple plants
Set up a system of equations:
x + y = 15
8x + 5y = 96
Isolate variable y (I will solve using substitution):
x + y = 15
y = 15 - x
Substitute the value of y in the second equation:
8x + 5(15 - x) = 96
Use distributive property:
8x + 75 - 5x = 96
Combine like terms:
3x + 75 = 96
Isolate variable x:
3x = 21
x = 7

The scatter plot shows the number of cars and trucks sold by 10 different employees at a car and truck dealership during a month.
How many employees sold more cars than trucks?
Enter your answer in the box.
Answer:
3 employees
Step-by-step explanation:
The best way to obtain a solution is to note the coordinate if each point on the scatter plot :
Where, the x - axis represents the number of cars sold and y - axis represents the number of trucks sold.
So, the number of employees that sold more cars than trucks exists where the x - axis value is greater than its corresponding y-axis value.
The scatter plot points : (2,4) (4,3) (3,7) (3,9) (4,8) (5,6) (5,7) (6,6) (9,0) and (10,1)
Points where x-axis > y-axis with each coordinate representing an employee :
(4,3) ; (9,0) and (10,1) = 3 employees.

Express 34C21 as a sum of two terms from pascals triangle.
Given:
The combination is:
[tex]^{34}C_{21}[/tex]
To find:
The [tex]^{34}C_{21}[/tex] as the sum of two terms from pascals triangle.
Solution:
According to the pascals triangle:
[tex]^{n+1}C_{r+1}=^nC_r+^nC_{r+1}[/tex]
We have,
[tex]^{34}C_{21}[/tex]
Using the pascals triangle formula, we get
[tex]^{34}C_{21}=^{33}C_{20}+^{33}C_{21}[/tex]
Therefore, [tex]^{34}C_{21}=^{33}C_{20}+^{33}C_{21}[/tex].
Lucia gave Brenda half of the cash she had in the store counter at the end of the day. Brenda put the money in her purse and added one half of the amount she had from her own savings. Brenda had saved half of what Lucia earned in the store that day. Brenda took her purse and went to the dog shelter and brought food and treat packet for 5 dogs. Each packet cost her $15. How much money did Lucia earn at the store that day?
Answer:
$100
Step-by-step explanation:
The amount Lucia gave Brenda = Half the amount in the store counter
The amount Brenda added to the money Lucia gave her = Half the amount in her (Brenda) savings
The amount Brenda had saved = Half of the amount Lucia earned in the store that day
The number of food and treat packets Brenda bought = 5
The cost of each packet = $15
Let x represent the amount Lucia earned and let y represent the amount Brenda saved
We have;
x/2 = y
x/2 + y/2 = 15 × 5 = 75
Therefore, we get;
y + y/2 = 75
(3/2)·y = 75
y = 75 × 2/3 = 50
y = 50
From x/2 = y, we have;
x/2 = 50
x = 2 × 50 = 100
The amount Lucia earned in her store that day, x = $100

An auto dealership sells minivans and sedans. In January, they sold 10 minivans and 20 sedans. In February, they sold 7 minivans and 14 sedans. During which month did the auto dealership sell a lower ratio of minivans to sedans?
Answer:
january = 10/20 = 1/2
februry = 7/14 = 1/2
so, we conclude that the auto dealership didn't have a lower ratio, since the ratio is equal in both months.

Step-by-step explanation:
Two runners started to run in the same direction at the same time. The speed of the first runner is 8 mph, and the speed of the second runner is 9.6 mph. What is the distance between them after 5 hours?
Answer:
8 miles
Step-by-step explanation:
9.6-8=1.6
1.6 times 5 equals 8 miles
It should be noted that after 5 hours, the distance between the two runners will be 8 miles.
How to calculate the distanceDistance = Speed × Time
For the first runner:
Distance covered by the first runner = Speed of the first runner × Time
= 8 mph × 5 hours
= 40 miles
For the second runner:
Distance covered by the second runner = Speed of the second runner × Time
= 9.6 mph × 5 hours
= 48 miles
Since both runners are running in the same direction, we subtract the distance covered by the first runner from the distance covered by the second runner to find the distance between them:
Distance between the runners after 5 hours = Distance covered by the second runner - Distance covered by the first runner
= 48 miles - 40 miles
= 8 miles

1 by 8 of the passenger of a train where children is there where 40 children traveling in the train on a Saturday how many Abbott were there in that that day?
Answer:
200 adults
Step-by-step explanation:
1/8 of the passengers (children) is 40
Total passengers in the train is 8/8
Therefore to get the total number of passengers is given by
(8/8) × 40 × (8/1)
= 240 passengers
Adults in the train = Passengers - Children
= 240 - 40
= 200 adults

S is the centroid of the triangle. Find IT if ST= 9
Answer:
IT = 13.5
Step-by-step explanation:
Recall: According to the Centroid theorem the Centroid of is ⅔ of the distance of the vertex of the triangle to the midpoint of the opposite side.
This means that:
ST = ⅔(IT)
ST = 9 (given)
Substitute
9 = ⅔(IT)
Multiply both sides by 3
3*9 = 2(IT)
27 = 2(IT)
Divide both sides by 2
27/2 = IT
IT = 13.5
There are 5 brown horses and 4 tan horses in a barn. Sonia will randomly select two horses to ride with her friend. What is the probability that
the first horse selected is tan and the second horse selected is brown?
20/81
5/18
2/9
1/20
Answer:
5/18
Step-by-step explanation:
The total number of horses present is 9
The probability that the first selected horse is tan is 4/9
So , now for the second choice , we are left with 8 total horses of which 5 is brown
The probability is 5/8
So the joint probability is the product of this two
That will be;
5/8 * 4/9 = 5/18
A ball is thrown into the air with an upward velocity of 36 ft/s. It’s height h in feet after t seconds is given by the function h = -16t^2 + 36t + 9. In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. What is the balls maximum height ?
Answer:
Time taken for the ball to hit the ground back = 3.08 s
Step-by-step explanation:
h(t)= -16t² + 48t + 4
when will rhe object come back to hit rhe ground?
When the ball is at the level.of the ground, h(t) = 0.
0 = -16t² + 48t + 4
-16t² + 48t + 4 = 0
Solving the quadratic equation
t = 3.08 s or t = -0.08 s
Since the time cannot be negative,
Time taken for the ball to hit the ground back = 3.08 s

It's B
Step-by-step explanation:
Three events A, B and C are defined over a sample space, S. Events A and B are independent. Events A and C are mutually exclusive. Given that P(A)= 0.04, P(B)=0.25, P(C)=0.20 and P(B/C)=0.15. Find for P(C/B)
Answer:
[(b/c)=0.15)]
Step-by-step explanation:
===================================================
Work Shown:
P(B/C) = P(B and C)/P(C) ... conditional probability formula
P(B and C) = P(C)*P(B/C)
P(B and C) = 0.20*0.15
P(B and C) = 0.03
------------
P(C/B) = P(C and B)/P(B) .... note the swap of B and C
P(C/B) = P(B and C)/P(B)
P(C/B) = (0.03)/(0.25)
P(C/B) = 0.12
------------
Extra notes:
The fact that events A and B are independent is not relevant.The fact A and C are mutually exclusive isn't used here either.This problem can be solved through Bayes' Theorem.Another alternative you can do is to set up a 3 by 3 contingency table to help solve this problem.Write the equation of the line that passes through the points (8, –1) and (2, –5) in standard form, given that the point-slope form is y + 1 = (x – 8).
Answer:
Ax + By = C is standard form.
y + 1 = (2/3)(x - 8)
distribute the (2/3)
y + 1 = (2/3)x - (16/3)
Multiply each term by 3 to clear the fractions.
3y + 3 = 2x - 16
Subtract 2x from both sides.
-2x + 3y + 3 = - 16
Subtract 3 from both sides.
-2x + 3y = - 19
Correct form typically has the leading coefficient as a positive number so multiply each term by - 1.
2x - 3y = 19

Answer:
The answer is 2x + -3y = 19
