To identify the density of a toy made using an unknown material, the toy is dropped into a basin filled with water and found to displace 125.4 mL of water. The figurine is then put on a scale and found to be 1.4 pounds in weight. What is the density of the material that this figurine was made from in pounds/inch^3? (Note: 1 mL = 0.0610237 inch^3)
The density of the material that this figurine was made from in pounds/inch³ is 0.183 lb/in³
To answer the question, we need to know what density is
What is density?Density is the mass per unit volume of a material.
It is given by ρ = m/v where
m = mass of material and v = volume of materialNow, given that the toy is dropped into a basin filled with water and found to displace 125.4 mL of water. It's volume is v = 125.4 mL
= 125.4 × 1 mL
= 125.4 × 0.0610237 in³
= 7.65237198 in³
Also, given that the figurine is then put on a scale and found to be 1.4 pounds in weight. It's mass is m = 1.4 lb
Density of the materialSo, the density of the material ρ = m/v
ρ = 1.4 lb/7.65237198 in³
ρ = 0.183 lb/in³
So, the density of the material that this figurine was made from in pounds/inch³ is 0.183 lb/in³

Find P(Not a 3).
A. 0.30
B. 0.15
c. 0.85
D. 0.70
Answer:
P(Not a 3)=0.85. This is option C.
Step-by-step explanation:
P(Not a 3) would include values 1,2 and 4.
Therefore, P(Not a 3) would be the combined totals of the probabilities of P(1), P(2) and P(4).
P(Not a 3)= P(1)+P(2)+P(4)
P(Not a 3)= 0.30+0.40+0.15
P(Not a 3)=0.85
Alternate method
P(Not a 3) is the same as 1-P(3)
P(Not a 3)=1-P(3)
P(Not a 3)= 1-0.15
P(Not a 3)=0.85

Determine the quadrant. I'm doing a final exam and I can't remember how to do this, pls help :)
Answer:
C
Step-by-step explanation:
In the unit circle
cos x corresponds with x
sin x corresponds with y.
Here, they are both negative so the angles lies in the third quadrant because both x and y is negative in the third quadrant
Step-by-step explanation:
the other answer we is correct.
here a few words about why :
the quadrants in a circle start in the right top corner. so, right top is number I.
left top is number II.
left bottom is number III.
right bottom is number IV.
simply because this goes with the growing angle. the angle starts at 0° at the right center. and then it grows counterclockwise and goes all around the circle until reaching 360° being equal to 0° again.

The scale of a model house to the actual house is 1:150. If the actual house size is 40 feet high, how many feet tall is the model? (round your answer to the nearest tenth
Answer: 0.3 feet
Work Shown:
(1 ft)/(150 ft) = (x ft)/(40 ft)
1/150 = x/40
1*40 = 150*x
40 = 150x
x = 40/150
x = 4/15
x = 0.2667 approximately
x = 0.3
Note: 0.3 ft = 0.3*12 = 3.6 inches

find the prime factorization of 405
Answer:
The factorisation of 405
405 = 5x3x3x3x3
Answer:
405 = 3 x 3 x 3 x 3 x 5 = 3⁴ x 5
Step-by-step explanation:
I'll factor 405 with the Factor Tree Method.
Step 1: Place the number 405 on top of the factor tree.
Step 2: Notice that 405 can be divided by 5 -> 405 = 5 x 81. The two branches from 405 become 5 and 81.
Step 3: Continue factorizing other numbers in the tree until you are left only with the prime factors, which you cannot further factorize.
Step 4: Write the number as the product of prime factors you got.
405 = 3 x 3 x 3 x 3 x 5 = 3⁴ x 5
The percent of voters between the ages of 18 and 29 that participated in each United States presidential election between the years 1988 to 2016 are shown in the table.
The function P gives the percent of voters between 18 and 29 years old that participated in the election in year t.
Pick two different values of t so that the function has a negative average rate of change between the two values. Determine the average rate of change.
Answer:
1.75
Step-by-step explanation:
Finding average rate of change :
A(x) = 42.7 - 35.7 / 1992- 1988A(x) = 7/4A(x) = 1.75The average rate of change for P between 1992 and 2000 is -1.025.
What is Average rate of change?The average rate at which one quantity changes in relation to another is known as the average rate of change function.
It can be determined by dividing the amount of one quantity's change by the amount of another quantity's change.
Average rate of change for a function 'f' in the interval [a, b] is,
A = f(b) - f(a) / (b-a)
So, the Average rate of change
= P(2000) - P(1992) / (2000 - 1992)
= (34.5 - 42.7) /(2000 - 1992)
= -8.2 / 8
= -1.025

The number of folders and notebooks in the equation is given by 3 and 5 respectively.
How to find number of folders and notebooks?let
x = number of foldersy = number of notebooksThe equation:
x + y = 8
0.50x + 1.0y = 6
From (1)
x = 8 - y
Substitute x = 8 - y into (2)
0.50(8 - y) + 1.0y = 6
4 - 0.50y + 1.0y = 6
4 + 0.40y = 6
4 - 6 = -0.40y
-2 = - 0.40y
y = -2 / 0.40
y = 5

A student allows 1/10 of her monthly income for books and 1/8 of her monthly income for clothing. If she budgets a total of $300 per month for books and clothing, what is her monthly income, x?
Answer: 1333.(3)
Step-by-step explanation:
Let her monthly income be x. Then,
(1/10)x + (1/8)x = 300
(4/40)x + (5/40)x = 300
(9/40)x = 300
x = 300 / (9/40)
x = 300*40/9
x = 12000/9
x = 1333 1/3 = 1333.(3)
