Answer:

Step-by-step explanation:

The volume of a cylinder is 3 times bigger than a cone with equal radius and height

To know this we have to compare the volumes of both solids first.

Let us assume the height and radius of the cone and radius are

6 and 2 mm respectively

so that the volume of a cone is given as

Volume of cone= 1/3 πr^2h

and the volume of cylinder is given as

Volume of cylinder= πr^2h  

1. Volume of cone= 1/3 πr^2h

Volume of cone= 1/3 *3.142*(2)^2(6)

Volume of cone= 75.408/3

2.  Volume of cylinder= πr^2h

Volume of cone= 3.142*(2)^2(6)

Volume of cone= 75.408

From the analysis the volume of a cylinder is three times bigger the volume of a cone with similar radius and height

Step-by-step explanation:

Answer:

There are 20,000 milligrams in one 2-decagram container . Thus option D is correct.

Step-by-step explanation:

The given information is one type of medicine in 2 decagram container.

Here, we know ,

      1 decagram = 10 grams

and, 1000 milligrams =1 gram

now -: 2 decagram = 2 × 10grams   {since 1decagarm = 10 grams }

                               = 20 grams .

then ,                   = 20× 1000milligrams {since 1 gram = 1000 milligrams}

                           =20,000 milligrams .

Hence, the correct option is D that is 20,000 milligrams .

Step-by-step explanation:

Answer:

The first one is a function, the second one is a function, and the third one is not a function.

Domain for the first one, just list the x values. Same for range.

Domain and range for the second one are both all real numbers.

For the last one, solve the quadratic, and find the vertex. The range will be all numbers greater than the y on the vertex, while the domain is all real numbers.

Step-by-step explanation:

An easy way to tell if something is a function or not is to check that each input (or x-value) has a different output (or y-value.) The first one is not a function because in the table, we see that 1 gives an output of 9, but later on you see 1 also gives an output of 20.

If you're ever given a graph and asked this question, do the vertical pencil test. Start at the left of the graph, and slide your pencil over the graph (vertically) and if your pencil ever hits more than one point at a time, it's not a function. Hope this helped!

Step-by-step explanation:

Answer:

y = -4x + 7

Step-by-step explanation:

Since they are parallel they must have the same gradient which is -4

[tex]y = mx + c[/tex]

m = -4

x = 0

y = 7

7 = -4 × 0 + c

c = 7

[tex]y = - 4x + 7[/tex]

Answer:

Weight of chocolate candies = 30lbs

Weight of sour candies = 30lbs

Step-by-step explanation:

We are told in the question that :

Chocolate candies worth $2.50 per pound

Sour candies worth $0.90 per pound. How much of each kind of candies should she combine to get 60 lb of mixed candies worth $1.70 per pound?

Let x represent the number of pounds of chocolate candies

Let 60 - x represent the number of pounds of sour candies

Hence, we have the equation

x × $2.50 + (60 - x) × $0.90 = 60 × $1.70

= 2.5x + 54 - 0.9x = 102

Collect like terms

2.5x - 0.9x = 102 - 54

= 1.6x = 48

x = 48/1.6

x = 30 lbs

x represent the number of pounds of chocolate candies,

60 - x represent the number of pounds of sour candies

= 60 - 30

= 30lbs

Weight of chocolate candies = 30lbs

Weight of sour candies = 30lbs

Therefore, she should combine 30lbs of chocolate candies and 30lbs of sour candies to get 60 lb of mixed candies worth $1.70 per pound.

Answer:

First one equals 16, second equals 4

Step-by-step explanation:

b*20=20b

320/20=16

Second

320/(b*20)

Replace b with 4 so it would be 320/(4*20)

4*20=80, 320/80=4

y +9 >= -1

Sum of a number(y) and 9. Is greater than or equal to negative one. Sum means add, so add y, and 9. It has to be atleast negative one, so greater than (0,1,2,3...), or equal to(-1).

Hope this helps, if you have more questions, feel free to ask.

The sum of a number y and 9 is at least -1 as an inequality is y + 9 ≥ 1.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

An expression,

The sum of a number y and 9 is at least -1.

To find the number in the numerator form,

The sum of y and 9,

y + 9

And the value is at least -1.

So,

y + 9 ≥ 1

Therefore, the inequality is y + 9 ≥ 1

#SPJ2

Answer:

(-infinity, -2/3)u(-2/3,0)u(0, infinity)

Step-by-step explanation:

since it is asking for f(g(x)) we plug g into x which looks like:

f(2/x)

now we plug that into the f(x) equation for all of the x's because that is what replaced the x so:

1/(2/x)+3

we look at the denominator so we can pull the 2/x+3 out and set it equal to zero, therefore solving for x

this gives us -2/3

and we get the 0 from g(x) 's denominator

that should be correct and hope this helps!
