90 minutes doing homework, 2/3 hour reading, and 540 seconds making his lunch for the next day. How many more minutes did Roberto spend doing homework than he did reading and making his lunch?

Answers

Answer 1

Answer:

41 minutes

Explanation:

According to this question;

- Roberto spent 90 minutes doing homework

- Roberto spent 2/3 hour reading. Since 1 hour = 60 minutes

2/3 hour = 2/3 × 60 = 40 minutes.

- Roberto spent 540 seconds making his lunch for the next day. Since, 60 seconds = 1 minute

540 seconds = 540/60

= 9 minutes.

The total amount of time Roberto spent reading and making his lunch is = 40 + 9 = 49 minutes.

Therefore, the amount of time Roberto spent doing his homework than reading and making his lunch is (90 - 49) = 41 minutes.

What is magma made of???

Answers

Answer:

Water vapor, Carbon dioxide, and sulfur

Explanation:

Hope that helps

Answer:

Magma made of Water vapor, carbon dioxide, and sulfur.

Explanation:

Like solid rock, Magma is a mixture of minerals. The high temperatures and pressure under Earth's crust keep magma in its fluid state.

Rocks change during metamorphism because the minerals need to be stable under the new temperature and pressure conditions. While metamorphic rocks are forming, the extreme heat changes the size and shape of the mineral grains in the rock.
Which statement describes the effect of the conditions described in this passage?

A. The need for stability may cause the structure of minerals to rearrange and form
new minerals
B. Great pressure from tectonic plate collisions can change rock into metamorphic
rock
C. The high temperatures of the magma can change nearby rock into metamorphic
rock
D. Metamorphic rocks are classified according to the arrangement of the grains in

The Go' for the reaction Citrate  Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate  α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?

Answers

Answer:

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

Explanation:

ΔG°' for Citrate is +6.64 kJmol-1

ΔG°' for Isocitrate is -267 kJmol-1

ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant

ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

how does energy cause global warming

Answers

Answer:

Global warming is caused primarily from putting too much carbon into the atmosphere when coal gas and oil are burned to generate electricity or to run our cars. These gases spread around the planet very fast, keeping the solar heat that would otherwise be radiated out into space!

Hope this helped

Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation and farming.

The environmental problems directly related to energy production and consumption include air pollution, climate change, water pollution, thermal pollution, and solid waste disposal. ... The emission of air pollutants from fossil fuel combustion is the major cause of urban air pollution

The Top 8 Causes of Global Warming

- Power Plants. Forty percent of U.S. carbon dioxide emissions stem from electricity production. ...

- Transportation. EPA reports state that thirty-three percent of U.S. emissions come from the transportation of people and goods.

No lactose individuals have two biological parents that are lactose intolerant

In this case lactose intolerance would be coded for a recessive gene (r). if both parents are lactose intolerant the would both be the genotype (rr) .

9. why Energy released by aerobic and anaerobic respiration in animal are not same.​

Answers

Answer: Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen. In animal cells anaerobic respiration often occurs during exercise. The glucose does not get fully broken down in this process, so it does not release its full potential energy. Instead of carbon dioxide and water it breaks down to form lactic acid and a small amount of energy.

Earth revolves around the tidal bulges created by gravitational forces.

Earth rotates in and out of a tidal bulge twice a day.

The moon's gravity increases over the oceans and decreases over the land.

Answers

Answer:

Earth rotates in and out of a tidal bulge twice a day.

Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.

The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.
