Answer:
1st sphere has r1 = 6
=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 6^2 = 144pi
=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 6^3 =288pi
2nd sphere has r1 = 15
=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 15^2 = 900pi
=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 15^3 =4500pi
=> S1/S2 = 144pi/900pi = 0.16
=> V1/V2 = 288pi/4500pi = 0.064
Hope this helps!

Jack and his cousin Emma are picking apples in their grandparents' orchard. Jack has filled 11 baskets with apples and is filling them at a rate of 5 baskets per hour. Emma has 8 full baskets and will continue picking at 6 baskets per hour. Once the cousins get to the point where they have filled the same number of baskets, they will carry them to the barn and then eat lunch. How long will that take? How much fruit will they have picked by then?
Answer:
3 hours
26 baskets each giving a total of 52 baskets
Step-by-step explanation:
Jack has already filled 11 baskets with apples and is filling them at a rate of 5 baskets per hour. This means that in x hours he would have filled an additional 5x basket to the initial 11 baskets. Therefore the number of baskets that Jack would have filled in x hours can be given by:
11 + 5x
Emma has already filled 8 baskets with apples and is filling them at a rate of 6 baskets per hour. This means that in x hours he would have filled an additional 6x basket to the initial 11 baskets. Therefore the total number of baskets that Emma would have filled in x hours can be given by:
8 + 6x.
The time it would take Emma and Jack to have completed the same number of baskets can be gotten by using this equation and solving for x:
11 + 5x = 8 + 6x
11 - 8 = 6x - 5x
x = 3 hours.
It would take them 3 hours to fill the same number of baskets.
The number of fruits Jack would have picked in 3 hours = 11 + 5(3) = 26 baskets.
The number of fruits Emma would have picked in 3 hours = 8 + 6(3) = 26 baskets.
Both Emma and Jack would have picked 26 baskets each, giving a total of 52 baskets
The population of the united states is 280 million. If 2 out of 3 americans know who the vice president is, how many americans know who the vice presdient is?
Answer:
186,666,667 Americans know who the vice president is
Step-by-step explanation:
In this question, we are tasked with calculating the number of USA citizens that know who the vice president is.
Now, in this question, we are made to know that the total population is set at 280 million with 2 out of three knowing who the vice president is.
What this means is that a fraction of the population at 2/3 knows who the vice president is
This fraction is equal to; 2/3 * 280,000,000 = 186,666,666.66666666
This is approximately equal to 186,666,667 people
Answer:
About 186.7 million people know who is the president of the United States.
Step-by-step explanation:
The number of US people who know who the vice president is (Mike Pence in 2020):
[tex]x = \frac{2}{3}\cdot (280\times 10^{6}\,people)[/tex]
[tex]x = 186.667\times 10^{6}\,people[/tex]
About 186.7 million people know who is the president of the United States.
Use the quadratic function to predict f(x) if x equals 2.
f(x) = -3x^2 + 180x - 285
Answer:
When x = 2, f(x) = 63.
Step-by-step explanation:
In order to find the value of f(x), you have to substitute x = 2 into the function :
[tex]f(x) = - 3 {x}^{2} + 180x - 285[/tex]
[tex]f(2) = - 3{(2)}^{2} + 180(2) - 285[/tex]
[tex]f(2) = - 12 + 360 - 285[/tex]
[tex]f(2) = 63[/tex]
Tom is twice as old as andy. in 4 years' time, the sum of their ages will be 32 years. Find andy's present age. Don't forget to identify your variable and answer in a full sentence.?
Answer:
8 years old
Step-by-step explanation:
Andy = x
Tom = 2x
So..
2x + 4 + x + 4 = 32
3x + 8 = 32
3x = 24
x = 8
Answer:
8 years old
Step-by-step explanation:
If we put Tom's age as x, since Andy is twice as old, Andy's age is 2x. Therefore, since Tom's age + Andy's age in two years is 32,
(x + 4) ← Tom's age in 4 years
(2x + 4) ← Andy's age in 4 years
We can now create an equation:
x+4 + 2x+4 = 32
Combining like terms, x + 2x = 3x, so now we have
3x + 4 + 4 = 32
4+4=8, so
3x + 8 = 32
-8 -8
3x = 24
Divide both sides by 3, and you have your answer ;
x = 8

a circle has a center located at 2 5 and passes through the point 10 3 answer
Determine the equation of the circle. Show how you arrived at your answer.
Write the equation of the tangent line to the circle at the point . Show how you determined your answer.
Answer:Explanation: The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
Step-by-step explanation:
The circle equation has a center located at (2, 5) and passes through the point (10, 3) is (x - 2)² + (y - 5)² = 68
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
The circle has a center located at (2, 5) and passes through the point (10, 3), hence:
[tex]Radius=\sqrt{(3-5)^2+(10-2)^2}=8.25[/tex]
The equation of the circle is:
(x-2)² + (y-5)² = 8.25²
(x - 2)² + (y - 5)² = 68
The circle equation has a center located at (2, 5) and passes through the point (10, 3) is (x - 2)² + (y - 5)² = 68

Answer:
17 / 8
Step-by-step explanation:
So the cosecant is equal to the hypotenuse ÷ opposite side
Hypotenuse = 17
Opposite side = 8
17 / 8
The measure of the cosecant of the angle B is 17/8.
What is the relation between cosecant and sine function?We can write the relation between cosecant and cosine function as -
cosec(x) = 1/sin(x)
Given is a right angled triangle.
We can write -
cosec(b) = 1/sin(b)
cosec(b) = 1/(p/h)
cosec(b) = (h/p)
cosec(b) = 17/8
Therefore, the measure of the cosecant of the angle B is 17/8.

water is being pumped into a 10-foot-tall cylindrical tank at a constant rate.
the depth of the water increases linearly
please help soon I have been stuck on this problem for a really long time.
at 1:30 pm the water depth was 2.4ft
it is now 4:00 and the water depth is 3.9 ft
what will the water depth be at 5:00?
Answer:
The depth of water at 5:00 is 4.5 ft.
Step-by-step explanation:
Depth of water at 1:30 PM = 2.4 ft
Depth of water at 4:00 PM = 3.9 ft
Change in time = 4 - 1:30 = 2.5 hours
Depth increased in 2.5 hours = 3.9 - 2.4 = 1.5 ft
Now, we are given that the depth of water is increasing linearly, so after 4:00 PM as well, the water depth will keep on increasing with the same rate as that of previous time intervals.
We have to find out the depth at 5:00 PM i.e. we need to find out the increase from 4:00 PM to 5:00 PM (1 hour) and then add it to depth at 4:00 PM.
Depth increased in 2.5 hours = 1.5 ft
Depth increased in 1 hour = 1.5 / 2.5 = 0.6 ft
Depth at 5:00 PM = Depth at 4:00 PM + Depth increased in 1 hour
[tex]\Rightarrow[/tex] 3.9 + 0.6 = 4.5 ft
Depth increased in 2.5 hours = 1.5 ft
So, The depth of water at 5:00 is 4.5 ft.
The depth of water at 5:00 is 4.5 ft.
Given that,
Depth of water at 1:30 PM = 2.4 ft Depth of water at 4:00 PM = 3.9 ft Si, Change in time = 4 - 1:30 = 2.5 hoursNow
Depth increased in 2.5 hours is
= 3.9 - 2.4
= 1.5 ft
Depth increased in 1 hour = [tex]1.5 \div 2.5[/tex] = 0.6 ft
Depth at 5:00 PM = Depth at 4:00 PM + Depth increased in 1 hour
= 3.9 + 0.6
= 4.5 ft

Answer:
volume = 31.5w
Step-by-step explanation:
A rectangular prism is a 3 dimensional figure that have 6 faces that are rectangular in shape. To ascertain the volume of a rectangular prism you need to know the length, width and height. The formula for the volume of a rectangular prism is represented below .
volume of a rectangular prism = LHW
where
L= length
H = height
W = width
volume = LHW
L = 7.5 ft
W = w ft
H = 4.2 ft
The expression for the volume of a rectangular prism with the following value above can be represented below.

y=mx + c
m is the gradient and c is the y intercept
m = (y 2 - y 1) / (x 2 - x 1) = (2-4) / ( 2-1) = -2
y= -2x + c
To find c, just sub one of the coordinates into the eqn:
By using the coordinates (1,4)
4 = -2(1) + c
c = 6
Therefore, the equation is y = -2x + 6

Compare interior intersections and
exterior intersections. How are they the
same? How are they different?
Answer:
Interior intersections are those intersecitons inside the main figure. For example, the intersection between two chords of a circle, that represents an interior intersection.
Exterior interseciton are those intersections which happens outside the figure, for example, the intersection of two tangent lines of a circle.
Basically, they are similiar, because both type of intersections are formed by the encounter between two lines or segments.
However, they are different, because each type is formed at different parts of the figure, one inside and one outside.
