Find the volumen of the semisphere and subtract the volumes of the two cylinders

1) Volume of the semisphere:

[1/2] (4/3)π(r^3) =[ 2π(1.5m)^3 ]/3 = 7.0686 m^3

2) Volumen of the cylinders:π(r^2)h

a) π(0.75/2m)^2 (1.75m) = 0.7731 m^3

b) π(1/2m)^2 (1.25m) = 0.9818 m^3

3) 7.0686 m^3 - 0.7731 m^3 - 0.9818m^3 = 5.3137 m^3

Answer: 5.3 m^3

S 8,000 a good estimate for the sum of 3,816 and 467?

Damm [24]

Answer:

it is not a good estimate.

Step-by-step explanation:3816 can be rounded to 4000 and 467 can be rounded to 500. Adding 4000+500 gives 4500, which isn't near 8000.

The sum of two consecutive integers is -239 find the two integers

xenn [34]

Answer:

The two consecutive integers are -119 and -120

Step-by-step explanation:

As we know that these two integers are consecutive, that means that they will have a difference of 1. This means that we can find the two integers by adding 1 to the sum of -239 and then dividing it by two

$1-239=-238\\\frac{-238}{2} =-119\\-119-1=-120$

nekit [7.7K]

Given: cos A = 5/13 = adj side / hypotenuse

The the opp side is given by (hypo)^2 = (adj)^2 + (opp)^2. Here,
13^2 = 5^2 + (opp)^2, so that
(opp)^2 = 169 - 25 - 144. Then opp = +12. All of these lengths are in Q I.
opp 12
Then sin A = -------- = -------- (answer)

What is 85 divided by 5 in distributive property

Lilit [14]

Answer:

Step-by-step explanation:

85 divided by 5 in distributive property

85 can be break into 80 and 5

80+5 is 85

Now we divide each term by 5

$\frac{85}{5} =\frac{80+5}{5} =\frac{80}{5} +\frac{5}{5}$
