The Figure Is Made Up Of Hemisphere And A Cylinder.what Is The Exact Volume Of The Figure?box [] Cm^3

Answers

Answer 1

Answer:

Data: (Cylinder)

h (height) = 8 cm

r (radius) = 5 cm

Adopting:

V (volume) = ?

Solving:(Cylinder volume)

Note: Now, let's find the volume of a hemisphere.

Data: (hemisphere volume)

V (volume) = ?

r (radius) = 5 cm

Adopting:

If: We know that the volume of a sphere is , but we have a hemisphere, so the formula will be half the volume of the hemisphere

Formula: (Volume of the hemisphere)

Solving:

Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)

Volume of the figure = cylinder volume + hemisphere volume

Volume of the figure = 628 cm³ + 261.6 cm³

The ratio of the number of Aaliyah’s pens to the number of Mariah’s pens was 2:3 at first. After Dad gave Aaliyah another 16 pens, the ratio became 2:1.
a) How many pens did Mariah have?
b) If Mariah gave away 6 pens, what would be the new ratio of the number Aaliyah’s pens (after Dad gave her 16 pens) to the number of Mariah’s pens?


y'all better help me with this one

Answer:

(2x + 16)/3x = 2/1

2x + 16 = 6x

4x = 16

x = 4

Aaliyah's pens = 2x = 2 × 4 = 8

the number of Maria's pen = 3x = 3 × 4 = 12 -----Part A

Answer:

answer is D.

Step-by-step explanation:

divide 2550 and 3.2 and get 796.875. multiply that by 3 and you get 2390.625.

Answer:

Option C 2794.8

Step-by-step explanation:

I'm not sure if it is correct but this is what I do

To find the total amount in the account you first need to find how much the interest rate is worth.

To find that you do 2550 times the interest rate which is 3.2 and you get 8160. Then you divide that by 100 which is 81.6

81.6 is the interest rate you get in one year. You multiply this by three and you get 244.8 which is the interest rate for three years.

Know add the interest rate to the amount of money deposited and you get your answer 2794.8

A zoo keeper was in charge of determining the population of meerkats at the zoo. He observed the meerkats and noted 8 of them and the special markings are on their face. The next day he went back out and observed the meerkats again. Out of the 20 that he saw, 4 of them were the same meerkats that he saw yesterday. How many meerkats can he assume are living at the zoo?

Answers

Answer:

16

Step-by-step explanation:

The zoo-keeper saw 8 special meerkats the day before and then only saw 4 special meerkats out of 20 the day after so 4 - 20 = 16.

Your answer would simply be 16

y-intercept= 3/5

slope= - (2/5)

Step-by-step explanation:

To do this problem you have to convert standard form into slope-intercept

2x+5y=3---> y= - (2/5)x+3/5

From this, we could refer to the slope-intercept notation...

y=mx+b

m=slope

b=y-intercept

So...

Looking at this we get

y-intercept= 3/5

slope= - (2/5)

Y intercept 3/5
Slope -(2/5)
