76 1 (1/24) x 100 = 4.17%
78 1 (1/24) x 100 = 4.17%
79 2 (2/24) x 100 = 8.33%
80 1 (1/24) x 100 = 4.17%
81 2 (2/24) x 100 = 8.33%
82 1 (1/24) x 100 = 4.17%
84 1 (1/24) x 100 = 4.17%
85 1 (1/24) x 100 = 4.17%
87 1 (1/24) x 100 = 4.17%
88 1 (1/24) x 100 = 4.17%
89 1 (1/24) x 100 = 4.17%
90 1 (1/24) x 100 = 4.17%

Here are the first five terms of a number sequence. 23 20 17 14 11 (a) Write down the 8th term of this sequence. *********
The 8th term of the sequence is 2.
To find the 8th term of the given number sequence, we can observe that the sequence is decreasing by 3 with each term.
Starting from the first term, which is 23, we subtract 3 repeatedly to get the subsequent terms:
23 - 3 = 20
20 - 3 = 17
17 - 3 = 14
14 - 3 = 11
We can see that each term is obtained by subtracting 3 from the previous term.
To find the 8th term, we continue this pattern:
11 - 3 = 8
8 - 3 = 5
5 - 3 = 2
Therefore, the 8th term of the sequence is 2.

Jack has another jar of 275 marbles that have the same distribution as the table above. Based on the information in the table, determine the number of yellow marbles
Based on the information provided in the table, Jack has 4h yellow marbles.
To determine the number of yellow marbles in the jar of 275 marbles, we can use the information from the table to find the proportion of yellow marbles in the first pouch.
According to the table, there are 4 yellow marbles out of a total of 25 marbles in the first pouch.
Therefore, the proportion of yellow marbles in the first pouch is 4/25.
To find the number of yellow marbles in the jar of 275 marbles, we can multiply this proportion by the total number of marbles in the jar.
Number of yellow marbles = (4/25) x 275 = 44

Find a dimensionless product relating the torque, (ML²T-²) produced by an automobile engine, the engine's rotation rate, (T-¹), the volume V of air displaced by the engine, and the air density p.
The dimensionless product relating the torque, rotation rate, volume, and air density is:
Pi = (torque) * (rotation rate)² * (volume)^(1/3)
To find a dimensionless product relating the torque (ML²T⁻²) produced by an automobile engine, the engine's rotation rate (T⁻¹), the volume V of air displaced by the engine, and the air density p, we can make use of the Buckingham Pi theorem.
The Buckingham Pi theorem states that in a physical problem involving n variables with k fundamental dimensions, there will be n - k dimensionless quantities that can be formed as products of powers of the original variables.
In this case, we have 4 variables with 3 fundamental dimensions: torque (M L² T⁻²), rotation rate (T⁻¹), volume (L³), and air density (M L⁻³). Therefore, we expect to have 4 - 3 = 1 dimensionless product.
Let's define the dimensionless product (Pi) as:
Pi = (torque)ᵃ * (rotation rate)ᵇ * (volume)ᶜ * (air density)ᵈ
To determine the powers (a, b, c, d), we equate the dimensions on both sides of the equation:
M L² T⁻² = (M)ᵃ * (T⁻¹)ᵇ * (L³)ᶜ * (M L⁻³)ᵈ
Equating the dimensions of mass (M):
1 = a + d
Equating the dimensions of length (L):
2 = 3c - 3d
Equating the dimensions of time (T):
-2 = -b
Solving these equations, we find:
a = 1
b = 2
c = 1/3
d = 0
This dimensionless product captures the relationship between these variables, independent of their specific units and scaling factors.

Answer:
[tex]\boxed{\boxed{\sf{\:\:\: \green{Percentage = 28\%}\:\:\: }}}[/tex][tex]\\[/tex]
Step-by-step explanation:
We know that the total number of kids is 150. We can find the number of kids with green, brown, and gray eyes using the given percentages:
[tex]\sf\dashrightarrow Green\: eyes = 6\: kids[/tex]
[tex]\sf\dashrightarrow Brown\: eyes = 0.52 \times 150 = 78\: kids[/tex]
[tex]\sf\dashrightarrow Gray\: eyes = 0.16 \times 150 = 24\: kids[/tex]
[tex]\\[/tex]
To find the number of kids with blue eyes, we can subtract the number of kids with green, brown, and gray eyes from the total number of kids:
[tex]\sf\dashrightarrow Blue\: eyes = 150 - 6 - 78 - 24[/tex]
[tex]\sf\dashrightarrow Blue\: eyes = 42\: kids[/tex]
[tex]\\[/tex]
Finally, we can calculate the percentage of kids with blue eyes by dividing the number of kids with blue eyes by the total number of kids and multiplying by 100:
[tex]\sf\implies Percentage = \dfrac{42}{150} \times 100[/tex]
[tex]\sf\implies Percentage = \dfrac{4,200}{150}[/tex]
[tex]\sf\implies Percentage = \green{28\%}[/tex]

The force of gravity on the rocket is 30 N/kg, the mass of the rocket stays constant while its weight varies
What is force of gravity?The force of gravity is the force exerted on an object by the earth or a planet.
Given that the force of gravity on an object when it is launched is 30 N/kg. This is three times larger than Earth's gravity. To determine what happens to the mass and weight of the object when gravity is 30 N/kg, we proceed as follows.
We know that weight, W = mg where
m = mass of object and g = gravitySince gravity g = 30 N/kg, we have that
W = mg
= m × 30 N/kg
= 30m
Now, we know that mass is an intrinsic property and weight is an extrinsic property. This means that the mass of the object is constant but its weight can change based on the object's position and depends on the amount of mass.
So, since the force of gravity on the rocket is 30 N/kg, the mass of the rocket stays constant while its weight varies

5m is the height of a cone with a diameter of 12 m whose volume is 188 m³.
To find the height of a cone, we can use the formula for the volume of a cone and solve for the height.
The formula for the volume of a cone is:
V = (1/3)× π × r² × h
Given that the diameter of the cone is 12 m, the radius (r) is half of the diameter, which is 6 m.
We are also given that the volume of the cone is 188 m³.
Using the formula, we can rearrange it to solve for the height (h):
h = (3V) / (πr²)
Plugging in the values:
h = (3 × 188) / (3.14 × 6²)
h = 564 / (3.14 × 36)
h = 564 / 113.04
h =4.9916
h=5
Therefore, the height of a cone with a diameter of 12 m whose volume is 188 m³ is 5 m.

Consider the equation below. (If an answer does not exist, enter DNE.)
f(x) = x3 − 3x2 − 9x + 3
The interval on which f(x) is increasing is (-∞, -1) and (3, ∞).
To find the interval on which the function f(x) = x³ - x² - 9x + 3 is increasing, we need to determine where the derivative of the function is positive.
First, let's find the derivative of f(x):
f'(x) = 3x² - 6x - 9
3x² - 6x - 9 = 0
3(x - 3)(x + 1) = 0
x - 3 = 0 or x + 1 = 0
x = 3 or x = -1
These are the critical points of the function.
Let's test a value from each interval:
For x < -1, let's use x = -2:
f'(-2) = 3(-2)² - 6(-2) - 9 = 12 + 12 - 9 = 15 > 0
For -1 < x < 3, let's use x = 0:
f'(0) = 3(0)² - 6(0) - 9 = -9 < 0
For x > 3, let's use x = 4:
f'(4) = 3(4)² - 6(4) - 9 = 12 - 24 - 9 = -21 < 0
From these test values, we can see that f(x) is increasing on the interval (-∞, -1) and (3, ∞).

[tex]\sf \dfrac{total\: donation}{ total \:sales} * 100 = percentage \:donated[/tex]
In this case, the total donation was $672 and the total sales were $8,400.
Substituting these values into the equation, we get:
[tex]\sf \dfrac{672}{8400} * 100 = percentage \:donated[/tex]
Simplifying this expression:
(0.08) * 100 = percentage donated
8% = percentage donated
Therefore, the home decor store donated 8% of $8,400 to hospitals.
