Question:A cone and a cylinder have the same base area. They also have the same curved surface area. If the height of the cylinder is 3m, then the slant height of the cone (in m) is
Answer:
Given the radius of cylinder and cone are the same because there base areas are same.
Curved surface of cylinder = curved surface area of the cone
∴2πrh=πrl
∴l=2h
Given, height of cylinder =3 cm
Therefore, slant height of cone =6 cm
The volume of the cone is 22π.
How to calculate the volume?Volume of a cylinder = πr²h
55π = πr²(5)
55π = 5πr²
r² = 55π/5π
r² = ✓11
r = 3.3
The volume of the cone will be:
= 1/3πr²h
= 1/3 × π × 3.3² × 6
= 1/3 × 11 × 6 × π
= 22π

Write an equation in slope-intercept form to represent the situation.
Answer: y = 50 x + 25
Step-by-step explanation:
A new law requires that 5% of an individual's income to be invested in the stock market. Your accounts show that you need to put $430 in the stock market this year. How much did you earn this year
Divide the amount you need to invest by the percentage.
430/0.05 = 8,600
You earned $8,600
Rewrite the following equation in slope-intercept form. y +3 = 1/4 (x − 4 )
Answer:
y = 1/4x - 4
Step-by-step explanation:
[tex]y + 3 =1/4(x - 4)\\y + 3 = 1/4x - 1\\y = 1/4x - 4[/tex]

Solve the system by substitution.
-2y - 10 = x
- 10x - y = -14
Answer:
x=2 and y=−6
sorry this is pretty long, I did not know if you needed the steps or not
Step-by-step explanation:
−2y−10=x;−10x−y=−14
Solve−2y−10=x for x
−2y−10=x
−2y−10+−x=x+−x
−x−2y−10=0
−x−2y−10+2y=0+2y
−x−10=2y
−x−10+10=2y+10
−x=2y+10
-x/-1=2y+10/-1
x=−2y−10
Substitute−2y−10 for x in−10x−y=−14
−10x−y=−14
−10(−2y−10)−y=−14
19y+100=−14
19y+100+−100=−14+−100
19y=−114
19y/19=-114/19
y=-6
Substitute−6 for y in x=−2y−10
x=−2y−10
x=(−2)(−6)−10
x= 2
x=2 and y=−6

Manco went scuba diving. As he dove deeper, the water pressure around him increased at a constant rate. The table compares Mancini's depth (in meters) and the water pressure around him(in atmospheres). what was the pressure around manco when he was 30 meters deep?
Answer:
4.0 atm
Step-by-step explanation:
it looks to be a proportional ratio so for every meter pressure increases by .1 atm so if you add .8 to 3.2 you get 4 atm

Alexander was offered a job that paid a salary of $24,000 in its first year. The salary was set to increase by 4% per year every year. If Alexander worked at the job for 5 years, what was the total amount of money earned over the 5 years, to the nearest whole number?
9514 1404 393
Answer:
$129,992
Step-by-step explanation:
The sum of a geometric series is given by ...
Sn = a1·(r^n -1)/(r -1)
Here, the first term is 24000, and the growth factor r is 1+4% = 1.04. The sum is then ...
S5 = 24000·(1.04^5 -1)/(1.04 -1) ≈ 129992
The total earned over 5 years was $129,992.

5(6p - 3) - 2 = 2(15p - 11) + 5
Answer:
p = 0
Step-by-step explanation:
step 1 (simplify) : 30p-17 = 30p-17 (add 17 to both sides)
step 2: 30p = 0 (divide both sides by 30)
p = 0

whats the answer to
-7y=7x+21
Answer:
y = -x - 3
x = -y - 3
Step-by-step explanation:
If solving for y,
-7y = 7x + 21
-y = -x + 3 (dividing everything by 7)
y = -x - 3
If solving for x,
-7y = 7x + 21
-y = -x + 3
x = -y - 3

where is the problem.....
Our world has always been faced with the problem of discrimination. It is one of the most discussed topics nowadays and throughout history. In all countries there is most likely at least one type of discrimination that affects different groups of people. The definition of discrimination is the denial of opportunity or equal rights for a specific group of people that may be differentiated by things such as their religion, color of skin, or gender. Discrimination can be confused with other terms such as prejudice and stereotype. The world we live in has been struggling with this sensitive subject for as long as we have recorded. Stereotypes are images held in our minds in regards to certain racial or cultural groups, without consideration of whether the images held are true or false. Stemming from stereotypes is prejudice. The prejudicial attitude occurs when we prejudge a person, good or bad, on the basis that the stereotypes associated with the person or group being prejudged are true. Discrimination is the combination of the terms mentioned above, but involves actually acting out with unfair treatment, directing the action towards the person or group. Prejudice and discrimination do not just occur racially, but it is found among gender, religion, culture, and geographical background. Remember that prejudice is a result of attitude and discrimination is a result of action.
Many people believe discrimination has made big steps forward, but has it really? If it has, why do people still get turned down, receive hate mail, or get ridiculed simply because they differ from each other. I guess these are questions we must ask ourselves. I guess you could also ask yourself if you have ever called anybody a name, looked at them different or judged them when you did not even know them or understand them. You may be thinking “That is not discrimination,” but, in fact, it is.
