Tell whether the sequence is arithmetic. If it is, what is the common difference?
-19.-11, -3,5,...
Oyes; 5
Oyes; 6
Oyes; 8
Ono
Answer:
the answer to this sequence is that: u count the difference between 19 and 11 , which is 8.
again try to see if the difference is same between 11 and 3, which is again 8.
so the commin difference in this sequence is = 8

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityStep-by-step explanation:
Step 1: Define
10.5x - 1.9 = 19.1
Step 2: Solve for x
Add 1.9 to both sides: 10.5x = 21Divide 10.5 on both sides: x = 2Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 10.5(2) - 1.9 = 19.1Multiply: 21 - 1.9 = 19.1Subtract: 19.1 = 19.1Here we see that 19.1 does indeed equal 19.1.
∴ x = 2 is a solution to the equation.
A grain silo is a cylinder with a hemisphere on top. In the Happy Farms grain silo, the height of the cylindrical portion is 30 feet. The radius is 10 feet. The volume of a cylinder is given by V = πr2h.
1. How can you find the volume of a hemisphere?
2. What is the volume of the hemisphere? Show your work.
3. What is the volume of the cylinder? Show your work.
4. What is the total volume of the grain silo? Explain how you found your answer.
Answer:
1) The volume of a hemisphere of radius R is equal to half the volume of a sphere of radius R.
Where the volume of a sphere of radius R is:
V = (4/3)*pi*R^3
In this case, the radius is R = 10ft
And pi = 3.14
2) Now we can just solve that equation to get:
V = (1/2)*(4/3)*3.14*(10ft)^3 = 2,093.33 ft^3
Where the (1/2) comes because the volume of the hemisphere is half the volume of a complete sphere, as we already said above.
4) We know that the volume of a cylinder is:
V = pi*(r^2)*h
where:
pi = 3.14
r represents the radius. The radius of the cylinder will be the same as the radius of the hemisphere, then r = 10ft
h is the height of the cylinder, in this case, h = 30ft
Then the volume is:
V = 3.14*(10ft)^2*(30ft) = 9,420 ft^3
The total volume is equal to the sum between the volumes of the cylinder and the volume of the hemisphere.
Then the total volume is:
Volume = 9,420 ft^3 + 2,093.33 ft^3 = 11,513.33 ft^3
Answer:
1. How can you find the volume of a hemisphere?
The volume of a hemisphere is half the volume of a sphere. The volume of a sphere is equal to V = (4/3)*pi*R^3
2. What is the volume of the hemisphere? Show your work.
V = (4/3)*pi*R^3
We can substitute pi for 3.14 and R for 10, and since we are finding the volume of a hemisphere, we divide by 2.
V = (1/2)*(4/3)*3.14*(10ft)^3
V = (1/2)*(4/3)*3.14*(10ft)^3 = 2,093.33 ft^3
3. What is the volume of the cylinder? Show your work.
The volume of the cylinder is 9,420ft^3
3.14*(10^2)*30=9,420
4. What is the total volume of the grain silo? Explain how you found your answer.
The total volume is 11,513.33 ft^3.
9,420 ft^3 + 2,093.33 ft^3 = 11,513.33 ft^3

Reuben is making a replica of the US flag for his school project.He uses a scale of 0.5 centimeter to 1 inch to draw the flag. The length of the scale drawing is 2.5 centimeters, and its width is 4.75 centimeters. What is the Perimeter of the scale drawing?
What is the Perimeter of the actual flag?
Answer:
scale = 14.5 cm perimeter
actual = 29 inch perimeter
Step-by-step explanation:
To find the perimeter of the scale drawing, we can just add up the scale sides.
This would be 2.5 + 2.5 + 4.75 + 4.75 = 14.5 cm perimeter
For the real flag, we know that for each cm on the scale flag, it represents 1 inch on the actual flag.
2.5/.5 = 5 inch length
4.75 / .5 = 9.5 inch width
5 + 5 + 9.5 + 9.5 = 29 inch perimeter
Donald is the CEO of a company and earns three times as much as the combined salary of his two vice presidents, Susan and Kurt. If Susan earns s and Kurt earns k, then how much does Donald earn in terms of s and k?
Answer:
Donald earnings = 3(s + k)
Step-by-step explanation:
Susan earnings = s
Kurt earnings = k
Combined salary = s + k
Donald earns earns three times as much as the combined salary of his two vice presidents,
Donald earnings = 3(s + k)
= 3s + 3k

The scores on a test given to all juniors in a school district are normally distributed with a mean of 73 and a standard deviation of 7. Find the percent of juniors whose score is below 66. The percent of juniors whose score is at or below 66 is
Answer:
The probability of juniors whose score is at or below =0.1587
The percentage of juniors whose score is at or below 66
P(X≤ 66) = 0.1587 = 15 percentage
Step-by-step explanation:
Explanation:-
Given mean of the Population (μ) = 73
Given standard deviation of the Population(σ) = 7
Let 'X' be the random variable in normal distribution
[tex]Z = \frac{x^{-}-mean }{S.D} = \frac{66-73}{7} = -1[/tex]
The probability of juniors whose score is at or below 66
[tex]P(X\leq 66 ) = P(Z\leq -1)[/tex]
= 1 - P( Z>Z₁ )
= 1-( 0.5 +A( Z₁)
= 0.5 - A(-1)
= 0.5 - A(1) (∵ A(-1) = A(1))
= 0.5 - 0.3413
= 0.1587
The probability of juniors whose score is at or below 66
[tex]P(X\leq 66 ) = P(Z\leq -1)[/tex] = 0.1587
The percentage of juniors whose score is at or below 66
P(X≤ 66) = 15 %

The minimum cost for an Uber ride is $9. A fee of $1.50 will be added for each additional mile. Write a piece wise function to model the situation
Answer: 9 + 1.50m
Step-by-step explanation:
From the question, we are informed that the minimum cost for an Uber ride is $9 and that a fee of $1.50 will be added for each additional mile.
A piece wise function to model the situation will be:
= 9 + 1.50m
where m = every additional mile
For example, if a person takes 4 additional miles, this will be calculated as:
= 9 + 1.50m
= 9 + 1.50(4)
= 9 + 6
= $15
Is a decorative block , made up of two solids -a cube and a hemisphere. The base of the block is a cube of side 6cm and the hemisphere fixed on the top has a diameter of 4cm. Find the total surface area of the block(use ⫪ = 3.14) *
Answer:
The surface area of the decorative block is 253.68 cm²
Step-by-step explanation:
The decorative block is a composite figure comprising of the following parts;
1) A solid cube with side length, S = 6 cm
2) A hemisphere with diameter, D = 4 cm
The surface area of the decorative block = The surface area of the solid cube + The surface area of the hemisphere
The surface area of the components of the decorative block are as follows;
The surface area of the solid cube = 6 × S² = 6 × (6 cm)² = 216 cm²
The surface area of the hemisphere = π·D²/4 + π·D²/2
∴ The surface area of the hemisphere = 3.14 × (4 cm)²/4 + 3.14 × (4 cm)²/2 = 37.68 cm²
∴ The surface area of the decorative block = 216 cm² + 37.68 cm² = 253.68 cm².

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(3, 5) = 15. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 5 = 15. In the next intermediate step the fraction result cannot be further simplified by canceling.

Answer:
Hope it helps u
Step-by-step explanation:
y∝ x
y=k*x
k=y/x
now putt the first point x=8 and y=2
we get k=2/8 =1/4
and also putt 2nd point ,
x=16,y=4 we get k=1/4 and similarly for 3rd and 4th point we also get k=1/4
hence the direct variation , equation become for all is same, that is
y=(1/4)x
A force of 84N is applied to an area of
15cm". Work out the pressure in N/cm².
cm3)
Answer: 5.6 N/cm^2
============================================
Work Shown:
Pressure = (Force)/(Area)
P = F/A
P = (84 N)/(15 cm^2)
P = (84/15) (N/cm^2)
P = 5.6 N/cm^2
For every square cm, 5.6 newtons of force is applied.
-------------
Extra info:
If you wanted to convert this to pascals, then you would need to convert 15 cm^2 to 0.0015 square meters. Then apply the formula above to get 56,000 pascals. 1 pascal is equivalent to 1 N/m^2.

Answer:
A and E
Step-by-step explanation:
9^3 / 9^3
Same number on top and bottom so 1 is an answer
look at the exponents, when dividing with exponents, you just subtract them, so it could also be 9^0, which is also 1
Answer:
A. 1 and E. 9^0
Step-by-step explanation:
9/9 = 1
You can check this by actually solving the problem:
9^3 = 9*9*9 = 729
So...
729/729 = 1
Also, any number to the power of zero is one, so 9^0 is also a correct answer
