Could Anyone Help And Give A Correct Answer?

Answers

Answer 1

Answer:

4.0 cm

Step-by-step explanation:

The volume of the frustum is the volume of the full cone (with height y + 7) minus the volume of the upper smaller cone (with height y).

Formula:

volume of cone = (1/3)πr²h

For the full cone:

r = 8 cm

h = y + 7

volume of cone [in cm³] = (1/3)π(8²)(y + 7)

volume of cone [in cm³] = (1/3)π(64)(y + 7)

volume of cone [in cm³] = (64π/3)(y + 7)

For the upper cone:

volume of cone = (1/3)πr²h

volume of cone = (1/3)π(4²)y

volume of cone = (16π/3)y

For the frustum:

volume = volume of full cone - volume of upper cone

volume = (64π/3)(y + 7) - (16π/3)y

volume = 64πy/3 + 448π/3 - 16πy/3

volume = 48πy/3 + 448π/3

Now we solve for y:

48πy/3 + 448π/3 = 670.2

50.265y + 469.144 = 670.2

50.265y = 201.056

y = 4.0

Answer: 4.0 cm

Find the equation of a line that passes through the points (3,2) and (5,6).
Leave your answer in the form y=mx+c

Answers

Answer:

Step-by-step explanation:This particular answer works out to be undefined because it is a straight line and there is no slope and no equation for it. I will show you how to work it out though so you will know how to do it with other problems. We will still be using the y = mx + b formula. First step is to find m. In order to find the slope we would use the equation:

m = (y2 - y1) / (x2 - x1) Note: The number behind the letter designates which x or y value you will use of the 2 (x, y) plots

m = (-5 - 2) / (3 - 3)

m = -7 / 0 Note: A number divided by 0 is undefined which means your slope is undefined

Since your slope is undefined your equation would be x = 3 because your x values are both 3.

Now let's assume your second (x, y) plot was actually (-3, -5).

m = (-5 - 2) / (-3 - 3)

m = -7 / - 6 Note: A negative divided by a negative is a positive. The negatives cancel each other out.

m = 7/6

Okay now back to our slope-intercept formula.

y = 7/6x + b

Now in order to figure out what b is, we will again take the plot point and plug the values into the equation. You can use either point because either way the answer will come out the same. In this case we will use (3, 2).

2 = 7/6(3) + b

2 = 21/6 + b Note: The easiest way to do the next part is to make the 2 into a fraction over 6

12/6 - 21/6 = b

-9/6 = b or -3/2

So now all we have to do is plug this value into our equation.

y = 7/6x - 3/2

formula
y-y2=m(x-x2)

m=(y2-y1)/(x2-x1)

let
(x1,y1)=(3,2)
and
(x2,y2)=(5,6)


m=(6-2)/(5-3)
=2
y-y2=m(x-x2)
y-6=2(x-5)
y=2x-10+6
y=2x-4

Divide both by 2, x=2.5

2. y+1.8=14.7

Subtract 1.8 from both sides to isolate the variable, x=12.9

3. 6=1/2z

Multiply each side by 2 to isolate the variable, 12=z

4. 3 1/4 = 1/2+w

Isolate the variable by subtracting 1/2 to both sides, 2 3/4 = w

5. 2.5t=10

Divide each side by 2.5 to isolate the variable, t=4

2) y = |10-x|, if x<10


Part B:

Answers

Answer:

Step-by-step explanation:

Rewrite without absolute value for the given conditions:

1) y = |x−3|+|x+2|−|x−5|, if x > 5

  y = x-3 + x + 2 - (x-5)

  y = x + 4

2) y = |10-x|, if x<10

   y = 10 - x

In both cases, the value of x is held to values that make the absolute value notation redundant, so they can be removed.

Answers

Answer:

y=-1/2x+2

Step-by-step explanation:

First, the slope of perpendicular line have negative reciprocal coefficients. In this case the coefficient is 2, The reciprocal of 2 is 1/2 and the negative of 1/2 is -1/2. So x will have a coefficient of -1/2.

Second, find the equation with a slope of -1/2 that passes through (-2,3). There are a few ways to do this. I like to plug the given x value into the expression -1/2x, so -1/2(-2) which equals positive 1 and for the line to pass through the point (-2,3) you need to add 2. So: y=-1/2x+2

Answer:

30 cakes

Step-by-step explanation:

For one cake alone, find a common denominator (which is 6). So [tex]2\frac{2}{3}[/tex] ([tex]\frac{8}{3}[/tex]) is equal to [tex]\frac{16}{6}[/tex] cups. [tex]\frac{1}{2}[/tex] is [tex]\frac{3}{6}[/tex] cups.

So for one cake, it takes [tex]\frac{19}{6}[/tex] cups of flour. Henry has [tex]\frac{570}{6} = 95[/tex] cups of flour.

If you divide the 570 by 19, Henry can make 30 cakes.

1 cake alone needs 6 cups.

2 2/3 = 8/3 = 16/6 cups.

1/2 = 3/6 cups.
For one cake, 19/6 cups flour needed
Henry has 570/6 (=95cups flour)
If you divide 570 by 19 Henry can make 30 cakes

Josue is saving up to buy a new phone. He already has $100 and can save an additional $5 per week using money from his after school job. How much total money would Josue have after 4 weeks of saving? Also, write an expression that represents the amount of money Josue would have saved in ww weeks.

Answers

Answer:

$120, 5w+100

Step-by-step explanation:

Josue starts with $100 and earns $5 a week over 4 weeks. That means you multiply 5 by 4 to get $20 dollars earned over 4 weeks. Then you add that to how much money he already has 100+20=$120 after 4 weeks. To get an expression, we have to take the amount of weeks and multiply it by 5 to show the 5 dollars he earns every week (5w) and then add the 100 dollars he already has to it, which gives us 5w+100.

Rahul was given a large box of 60 chocolates for his birthday. If he eats exactly 4
chocolates each day, how many chocolates would Rahul have remaining 9 days after
his birthday?

Answers

Answer:

He'll have 24 chocolates remaining.

Step-by-step explanation:

Lets make an equation to represent the problem where x = the number of days and c = chocolates remaining.

60 - 4x = c

Since he ate four chocolates everyday for 9 days, the x in this equation would be 9.

Multiply 9 by 4 to get 36, Then subtract that from 60 to get 24.

In 2013, the quantity was of [tex]7.07 \times 10^9[/tex].In 2000, the quantity was of [tex]1.43 \times 10^{10}[/tex]

Hence, 2.04 times more pennies were minted in the year 2000 compared to the year 2013.

Hence, applying the proportion:

[tex]\frac{1.43 \times 10^{10}}{7.07 \times 10^9} = \frac{14.3 \times 10^9}{7.07 \times 10^9} = 2.04[/tex]

c) P(R ∪/or G) = P(R) + P(G) - P(R ∩/and G)

replace those with actual values;

P(R or/∪ G) = 1/3 + 1/3 - (1/3 x 1/3) = 2/9

d) There are 2 other colors besides red out of 3, so therefore it is a 2/3 chance

e) The probability of getting a yellow is not mentioned therefore it is impossible.

5.

a) There are 7 possible outcomes

b) There is only one 6 in the spinner out of 7 numbers, so it will be a 1/7 chance

What is the solution to the equation?
x^2=40

Will give brainliest if correct and explained!!

Answers

Answer: 2√10

Step-by-step explanation:

A way we can find what x equals, is to find the opposite of what ever sign is on a side, in the equation x^2=40, the opposite of squaring is to find the square root of it.

It is important that what you do to one side, you do to the other.

So we have to square root both sides so we can get rid of the ^2 on x to get x =. This would look like √x^2 = √40

The square root of x^2 would revert back to just x

To find the square root of 40, its important to first see if its a perfect square. In this scenario, it isnt. Because it isnt, we have to find the closest perfect square that we can multiply to get 40, in this equation, the closest would be 4 so we do 4*10.

Then we reduce the 4 by square root and we get 2

Then we cant do anything else with the 10, so we would right the answer as a radical, with the square root you got from the perfect square on the outside and the remainder on the inside of the square root, like x√r where x is the number obtained from square root and r is the remainder that we cant do anything else with.

After doing this, we get the answer 2√10, which can be said "two radical ten"

James's bag has 15 red marbles, 10 blue marbles and 5 green marbles.

They each take a marble out of their bag without looking.

Solve;

Alex have 10 Blue marbles so 10 out of 20 are Blue.

James has 10 Blue Marbles so 10 out of 30 are Blue.

Hence, [A] They both have the same probability of picking a blue marble.

Alex have 10 red and 10 blue which 10 = 10

thus, [B] The probability of Alex picking a red marble is 50%.

Alex's have 10 red marbles and James's have 15 red marbles.

10 out of 20 of them are red. Thus, that 50%

15 out of 30 of them are red. Thus, that 50%

50%  = 50%

Hence, [C] They both have the same probability of picking a red marble.

is true.

James have 15 red, 10 Blue, 5 Green marbles.

15 + 10 + 5 =30 [ Total ]

5 out of 30 is Green

5/30 = 0.16666666666

Round = 16.67%

Hence, [D]  The probability of James picking a green marble is 5%.

is False.

15 out of 30 and 10 out of 20

15/30 = 50% and 10/20 = 50%

Thus, [E] James has a higher chance of picking a red marble than Alex.
