A soup bowl is in the shape of a hemisphere with a diameter of 10 cm. What is the approximate maximum volume of soup that the bowl can hold? A 2.094 cm B. 524 cm C. 262 cm

Answers

Answer:

C. 262 cm

Step-by-step explanation:

Use the formula for the volume of a sphere, V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]

Since the diameter is 10 cm, the radius will be 5 cm

Plug in the radius into the formula:

V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](5³)

V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](125)

V = 523.6

Since the bowl is a hemisphere, divide this by 2:

523.6/2

= 261.8

Rounding to the nearest cm, the volume of the bowl is 262 cubic cm.

So, the correct answer is C. 262 cm

What is the exact circumference of the circle?

Answers

Answer:

circumference = 22.2144 or 5π√2

Step-by-step explanation:

the diameter of the circle would be equal to the diagonal of the square.

Using the Pythagorean theorem:

D² = 5² + 5²

D² = 50

D = 7.0711 or 5√2

circumference = πD = 5π√2 = 22.2144

Answer:

diagonal or diameter =√(5²+5²)=5√2unit

therefore radius =5/2√2unit

circumference of circle =2πr=2×π×5/2×√2=5π√2unit

Answer:

Jessica's trains travels at a faster speed

Step-by-step explanation:

From the question,

Using the graph,

The total distance distance traveled by Khalid after 2 hours is

d = 280 mi.

S = d/t....................... Equation 1

Where S = Khalid's speed, d = Khalid's distance, t = time.

S = 280/2

S = 140 mph.

From the euqation,

The total distance traveled by Jessica after 2 hours is

y = 150×2

y = 300 mi.

Also Using

S' = d'/t

Where S' = Jessica's speed, d' = Jessica's distance

S' = 300/2

S' = 150 mph.

From the above, Jessica's trains travels at a faster speed

How does Ray Bradbury's description of Margot's appearance in "All Summer in a Day" also give insight into her feelings?

Answers

Answer:

The description of Margot as a frail girl who had lost her vibrancy shows that she was in eager anticipation of the rain.

Step-by-step explanation:

The short story, "All Summer in a Day", tells of how a girl named Margot always stood differently from her classmates because she eagerly anticipated a time when the sun will come out as the scientists projected. It had been raining in this planet, Venus for seven years non-stop.

Margot who came from planet earth some five years ago could still clearly recall how the sun looked like and despite her description of it, the children still doubted her. On the day the sun finally came, the children locked Margot in a closet and she was unable to see the sun.

Jack bought 4 hot dogs and 3 sodas for $15.50. Mack bought 3 hot dogs and 2 sodas for $11.25. Find the cost of each.

Answers

Answer:

Hot dogs: $2.75

Sodas: $1.5

Step-by-step explanation:

Hot dogs = x

Sodas = y

4x + 3y = 15.5

3x + 2y = 11.25

First find the value of the hot dogs by canceling out y:

2(4x + 3y) = 2(15.5)

3(3x + 2y) = 3(11.25)

= 8x + 6y = 31

9x + 6y = 33.75

x = $2.75 (Minus bottom equation from the top to isolate x)

Plug in for x to get y:

3(2.75) + 2y = 11.25

2y = 11.25 - 8.25 (Isolate the y)

2y = 3

y = 3/2, or $1.5

[tex]\text{solve the following equation : }[/tex]
[tex] \sf\tan^{2}(\theta)-(1+\sqrt{3})\tan(\theta)+\sqrt{3} = 0[/tex]

Answers

tan²( θ ) - (1 + √3) tan (θ) + √3 = 0

tan²( θ ) - (tan (θ) + √3 tan (θ)) + √3 = 0

tan²( θ ) - tan (θ) - √3 tan (θ) + √3 = 0

tan( θ ) ( tan (θ) - 1) - √3 ( tan (θ) - 1 ) = 0

( tan( θ ) - 1 ) ( tan( θ ) - √3 ) = 0


tan( θ ) - 1 = 0

θ = π/₄

tan( θ ) - √3 = 0


θ = π/₃


so θ = π/₄ and θ = π/₃

Answer:

[tex] \huge \boxed{ \red{ \boxed{\begin{cases} \theta = {45}^{ \circ} \\ \theta= {60}^{ \circ} \end{cases} }}}[/tex]

Step-by-step explanation:

to understand thisyou need to know about:trigonometryPEMDASlet's solve:

distribute tan(θ):

=>tan²(θ)-(tan(θ)+√3tan(θ))+√3=0

remove parentheses:

=>tan²(θ)-tan(θ)-√3tan(θ)+√3=0

so this equation is now in standard form i.e ax²+bx+c=0

we can solve by factoring as we solve quadratic equation

factor out tanθ:

=>tan(θ)(tan(θ)-1)-√3tan(θ)+√3=0

factor out -√3:

=>tan(θ)(tan(θ)-1)-√3(tan(θ)-1)=0

group:

=>(tan(θ)-√3)(tan(θ)-1)=0

separate it as two different equation:

[tex] \implies \begin{cases} \tan( \theta) - 1 = 0 \\ \tan( \theta) - \sqrt{3} = 0 \end{cases}[/tex]

add 1 and √3 to both sides to first and second equation respectively:

[tex] \implies \begin{cases} \tan( \theta) - 1 + 1 = 0 + 1 \\ \tan( \theta) - \sqrt{3} + \sqrt{3} = 0 + \sqrt{3} \end{cases} [/tex]

[tex] \implies \begin{cases} \tan( \theta) = 1 \\ \tan( \theta) = \sqrt{3} \end{cases} [/tex]

[tex] \therefore \begin{cases} \theta = {45}^{ \circ} \\ \theta= {60}^{ \circ} \end{cases} [/tex]

If 12% of the air leaks out of Brian's bicycle tire every day, what percent of the air will be left after 2 days? After a week? Round your percents to 2 decimal places.

Answers

Answer:

77.44%

49.87%

Step-by-step explanation:

If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air

on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056

Air left on the second day = 88% - 10.56% = 77.44%

After a week = (100 - 12%)^7 = 49.87%

Is my report grammar amazing? Need help asap, please.The melting of the polar ice caps. There are millions of polar ice caps in the world and there are Millions of wildlife and organisms living on them. They can grow enormous up to 50,000 square kilometers. They take up 14.6 million km of the earth. They are getting smaller day by day and night by night. They are melting. At the rate that it is melting by 2035, the polar ice caps will be gone and all coastal cities will be flooded and destroyed. The polar ice caps would have been around for millions of years in the world's oldest architecture. There are so many animals that live under polar ice caps. Some animals are brown bears, polar bears, arctic foxes and wolves, whales, birds, fish, krill, penguins, etc. There are so many animals that stay alive on and under the ice caps. The environment is perfect for the animals and we are ruining it for those animals. The ecosystem under the icecaps is amazing. It is a great place for fish, krill, and aquatic organisms. It is a safe spot for small animals because the animals on top of the ice caps won't go into the water unless they have to because there are bigger predators in the water like leopard seals, killer whales, and big fish. More and more animals die every day because the ice caps are getting smaller and smaller There are big rivers that are flowing into the ocean from the ice caps. These Rivers are bad because they flood everywhere and it ruins animals' homes and shelters. It is also good because now the animals can drink and not have to worry about getting eaten by a leopard seal or a killer whale, but now the animals will overpopulate and be indeed for more food. Every day billions of tons of ice melt, and the ice caps have 90% of the freshwater on earth. The ice caps are breaking apart and big chunks of them are starting to fall into the water which isn't good because they are raising the sea level. They are not good to have in our ocean because the broken pieces take a long time to melt and those big chunks float and also hit boats or other ice caps that break apart them. It is not good to have thousands of ice caps scattered around the take up The only way we can slow down the process of melting is if we stop burning so much energy and use solar or electric power to do our daily tasks driving places and burning trash. Electric cars are great for the world but we need to find a better power source because it is hard to get so much electrical energy from the earth. Solar power is another way millions of people use solar power on their roofs of their houses so that the power that they receive from the sun is subtracted from their electrical bill. It is a great power source but it is not as effective because it requires an extremely strong energy source to power them. Luckily we have the sun and that helps out a bunch. Climate change also is a huge factor in the melting of the polar ice caps. When the climate changes everything has to adjust to that climate and the ice caps can't. Over the past 100 years, the climate has changed by 1.0o F. That is a lot. Even though it seems so small for the climate to change it takes a lot of burning fuel and waste. We cut and burn so much wood, metal, biofuel, trash, etc. We all do it even if you think you recycle some of it still is burned so try to reuse your trash as much as possible. When we reuse something it proves that something can be used twice rather than throwing it out without seeing what you could do with it. You can reuse anything like plastic water bottles, home depot buckets, plastic straws, fruit cups, and much more. Everything helps the environment and you should make a difference by going out of your way to do things for the environment. Picking up trash on the road, sidewalk, forest, buildings, or anywhere you can think of. When you do a small act of kindness you can feel better. You also help the ice caps from melting faster.
