Answer:1072.3
Step by step:
use the hemisphere formula which is 2/3*pie*r^3
substitute 8 centimeters into the equation.
The Volume of a hemisphere is,
⇒ Volume of hemisphere = 1071.78 cm³
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
Radius of hemisphere = 8 centimeters
We know that;
Volume of hemisphere = 2/3 (πr³)
Hence, We get;
⇒ Volume of hemisphere = 2/3 × 3.14 × 8³
⇒ Volume of hemisphere = 1071.78 cm³
Thus, The Volume of a hemisphere is,
⇒ Volume of hemisphere = 1071.78 cm³

fiza is mixing antifreeze and water. she has 21 litres of a mixture of antifreeze and water in the ratio 5:2 .
A . how much water would she have to add to get1:1.
B . how much water would she have to add to get 1:2
9514 1404 393
Answer:
9 liters24 litersStep-by-step explanation:
The amount of water in the mix is 2/(5+2) = 2/7 of the volume of the mix. That amount is ...
(2/7)(21 liters) = 6 liters
Then the other 21-6 = 15 liters are antifreeze.
A) To make the mix 1 : 1, 15-6 = 9 liters of water need to be added.
__
B) To make the mix 1 : 2, The total amount of water needs to be brought to 30 liters. 15 more liters need to be added for a total of 24 added liters of water.

The family’s leaders have pulled off three of the great marketing triumphs of the modern era: The first is selling OxyContin; the second is promoting the Sackler name; and the third is ensuring that, as far as the public is aware, the first and the second have nothing to do with one another.
To the extent that the Sacklers have cultivated a reputation, it’s for being earnest healers, judicious stewards of scientific progress, and connoisseurs of old and beautiful things. Few are aware that during the crucial period of OxyContin’s development and promotion, Sackler family members actively led Purdue’s day-to-day affairs, filling the majority of its board slots and supplying top executives. By any assessment, the family’s leaders have pulled off three of the great marketing triumphs of the modern era: The first is selling OxyContin; the second is promoting the Sackler name; and the third is ensuring that, as far as the public is aware, the first and the second have nothing to do with one another.
If you head north on I-95 through Stamford, Connecticut, you will spot, on the left, a giant misshapen glass cube. Along the building’s top edge, white lettering spells out ONE STAMFORD FORUM. No markings visible from the highway indicate the presence of the building’s owner and chief occupant, Purdue Pharma.
Originally known as Purdue Frederick, the first iteration of the company was founded in 1892 on New York’s Lower East Side as a peddler of patent medicines. For decades, it sustained itself with sales of Gray’s Glycerine Tonic, a sherry-based liquid of “broad application” marketed as a remedy for everything from anemia to tuberculosis. The company was purchased in 1952 by Arthur Sackler, thirty-nine, and was run by his brothers, Mortimer, thirty- six, and Raymond, thirty-two. The Sackler brothers came from a family of Jewish immigrants in Flatbush, Brooklyn. Arthur was a headstrong and ambitious provider, setting the tone—and often choosing the path—for his younger brothers. After attending medical school on Arthur’s dime, Mortimer and Raymond followed him to jobs at the Creedmoor psychiatric hospital in Queens. There, they coauthored more than one hundred studies on the biochemical roots of mental illness. The brothers’ research was promising—they were among the first to identify a link between psychosis and the hormone cortisone—but their findings were mostly ignored by their professional peers, who, in keeping with the era, favored a Freudian model of mental illness.
Concurrent with his psychiatric work, Arthur Sackler made his name in pharmaceutical advertising, which at the time consisted al

Fifty students were eating lunch in the school cafeteria. The ratio of boys to girls was 25:25. Mrs. White asked Kym to explain what that ratio meant. Kym said it meant that 25% of the students in the cafeteria were boys.
Explain why Kym is incorrect.
Answer:
Kym is wrong because instead of 25% it would be 50 percent
Step-by-step explanation:
Answer:
Sample Response: The ratio of boys to total students was 25:50. Written as a fraction, this is 25/50. Rewrite the fraction with a denominator of 100 to 50/100. So 50% of the students were boys.

Do you agree with the statement that " cubic functions must have at least 1 x-intercept but not more than 3, whereas quadratic functions may or may not have x-intercepts
Answer:
Yes, I agree
Step-by-step explanation:
For the cubic function
A cubic function is represented as:
[tex]f(x)=ax^3+bx^2+cx+d[/tex]
A cubic function may have 1, 2 or 3 x intercepts. This is shown below
For 3 x intercepts
[tex]y = x^3 - x[/tex]
Equate y to 0
[tex]x^3 - x = 0[/tex]
Expand
[tex]x(x^2 - 1) = 0[/tex]
Express [tex]x^2 - 1[/tex] as difference of two squares
[tex]x(x - 1)(x +1 ) = 0[/tex]
x = 0 or 1 or -1
For 2 x intercepts
[tex]y = x^3 - x[/tex]
[tex]y =(x-5)^2)(x+7)[/tex]
Equate y to 0
[tex](x-5)^2(x+7) = 0[/tex]
Expand
[tex](x-5)(x-5)(x+7) = 0[/tex]
x= 5 or x = -7
For 1 x intercept
[tex]y = x^3[/tex]
Equate y to 0
[tex]x^3 = 0[/tex]
Take cube roots of both sides
[tex]x = 0[/tex]
It has been shown above that a cubic function may have 1, 2 or 3.
So, I agree to the statement
For the quadratic function
A quadratic function will not have any x intercept when the function can not be factorized;
E.g.
[tex]y = x^2 + x + 17[/tex]
The above function has no x intercept.
A quadratic function will have at least 1 x intercept when the function can be factorized;
E.g.
[tex]y = x^2- 6x + 9[/tex]
Equate y to 0
[tex]x^2- 6x + 9 = 0[/tex]
Expand
[tex]x^2 - 3x - 3x + 9 = 0[/tex]
[tex](x - 3)(x-3) = 0[/tex]
[tex]x = 3[/tex]
We've shown that a quadratic may have no x intercept, and it may also have x intercept(s)
Hence, I agree to both statement

The distance between town a and town b on a Map is 14.6cm. If the scale is 1cm=14miles, what is the actual distance between towns
Answer:
204.4 miles
Step-by-step explanation:
Given data
we are told that on the map the distance is 14.6cm
scale
1cm=14miles
hence if
1cm represents 14miles
then 14.6 cm will be x
cross multiply
x= 14.6*14
x=204.4 miles
Hence the distance is 204.4 miles

What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
From the figure,
Let the triangle having ∠x have the following angles:
∠A and ∠B.
Now,
∠A is opposite to 85°.
So,
∠A = 85°
98° and one angle are corresponding angles.
So,
One angle = 98°
Now,
One angle and ∠B is a straight angle.
So,
∠B + 98 = 180
∠B = 180 - 98
∠B = 82°
Now,
The sum of the triangle is 180.
This means,
x + 82 + 85 = 180
x = 180 - 167
x = 13
Thus,
The value of x is 13.
