a cone has a volume of 6 cubic inches. what is the volume of a cylinder that the cone fits exactly inside of
ella [17]

Answer:

= 18 cubic inches

Step-by-step explanation:

The volume of a cone is given by the formula;

V = 1/3 × base area × height

While that of cylinder is given by the formula;

Volume = Base area × height

Since we need the cylinder to fit exactly inside the cone, then it  means that their bases are the same and heights are the same.

Therefore;

The cone has three times less volume compared to the cylinder.

Thus;

Volume of the cylinder = Volume of cone × 3

                                       = 6 In³ × 3

                                       <u>= 18 cubic inches</u>

What is x equal to ? Link down below.
scZoUnD [109]

Answer:

50

Step-by-step explanation:

Because of supplementary angles that line has to equal to 180

180-75 = 105

so 105 = (2x + 5)

you can subtract 5 from each side and get

100 = (2x)

then divide each side by 2 and you get

x = 50

you can check it by doing (2 x 50 + 5)

2 x 50 = 100 + 5 = 105 + 75 = 180

Explain the process and the properties you have to use to solve the logarithmic equation: log(3)x + log(3)4 - 2 log(3)3 = 2
Akimi4 [234]

81/4

Step-by-step explanation:

log_{3}(  \frac{4x}{{3}^{2} }   )  = 2

{3}^{2}  =  \frac{4x}{ {3 }^{2} }

9=4x/9

81=4×

x=81/4

adding logs means elements are multiplied, subtracting means divide. number in front of log is raised to power

base of log is raised to power of element after =

element in log is then equal to log base raised to power

solve resulting equation

Can someone help if you can’t tell I suck at math?
Ad libitum [116K]

Answer:

Step-by-step explanation:

1. There will be 9 roses in total.  

Probability Orange: 2/9

Probability Yellow: 3/9 = ⅓  

Probability Pink: 4/9

2. 4/7 as there are 7 bowls in total and 4 are chocolate.  

3. 4/10 = ⅖ (simplified) There are 10 fruits in total and 4 are apples.  

4. 5/15 = ⅓ (simplified) There are 15 cars in total and 5 or them are cooper minis.

5. 2/6 = ⅓ (simplified) There are 6 textbooks and 2 of  them are math.  

6. 13/20 There are 20 drinks and 13 of them are lemonade.  

7. There are 10 toys in total.  

Probability toy cars: 3/10

Probability dolls: 2/10 = ⅕ (simplified)  

Probability balls: 5/10 = ½ (simplified)  

8. In total the number of red roses and lilies are 7. There are 10 flowers in total so the number of jasmines are 3. Therefore the probability of getting a jasmine is 3/10  

9. 20/50 = ⅖ (simplified) There are 50 papers in total and 20 of them are yellow.  

10. 8/18 = 4/9 (simplified) There are 18 buses and 8 of them are air conditioned.
