what is the opposite -2/5

Answer:

Average rate of temperature increase is 2 degrees per hour

Step-by-step explanation:

Here, we want to calculate the average rate of increase in temperature

From what we have above, we can calculate this by dividing the total temperature rise by the number of hours

The total temperature rise is 6 + 4 = 10 degrees

This means that the temperature rose by 10 degrees between 10 am and 3 pm

The number of hours between 10 am and 3 pm is 5 hours

So the average rate of temperature increase is 10 degrees/ 5 hours = 2 degree per hour

Answer:

Step-by-step explanation:

we see that when x = 0 the y = 7 so we already kno our y intercept is 7

then we can see that it decreases by 4 each time so our slope is -4x

now we just put that in equation form

y=-4x+7

Answer: -14

Step-by-step explanation:

Answer:

Math seems difficult because it takes time and energy. Many people don't experience sufficient time to "get" math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. We often end up with a weak structure that is doomed to collapse at some point.

Math is hard because it is a non-intuitive, non-natural activity. Math don't happen by chance only, it only happens with deliberate, focused work. For this you expend a lot of energy and cause a lot of mental strain, you put yourself on an uncomfortable condition for hours, days, sometimes weeks to solve a problem.

But some people love math, like me, because they study math more than others. If you study more and learn more about math, then you’ll start to feel more comfortable because you’ll be ahead of the class when your teacher teaches you something.

The most important thing is to keep trying and never give up.

Hope this helps! :)

Answer:

28.32

Step-by-step explanation:

using the formula [tex]a^{2} +b^{2} =c^{2}[/tex], you get [tex]21^{2} +19^{2} =c^{2}[/tex].

then you get [tex]441+361=802[/tex]

your answer needs to be the square root of 802.

the square root of 802 is 28.319604517

Which rounded to the nearest tenths is 28.32

Answer:

He would have to make 12 sales a week in order to make $240

Step-by-step explanation:

So every week the job pays him $60

And $15 more every sell he makes So 15x12=180

So if he  makes 12 sells in a week he will make $180 dollars.

Plus the 60 the job pays him every week

So 180+60=$240

They won 2/3 of the games, or about %66 percent.

Step-by-step explanation:

There is a total of 30 games played, becuase 20+10 is 30, and they won 20 out of 30 of the games. or 20/30. You then divide 20/30 and you will get .6666 which is 66%.

Answer:

30 %

Answer:

5 gallons of gas

Step-by-step explanation:

From the above question:

If:

80 miles = 4 gallons of gas

100 miles = x gallons of gas

Cross Multiply

80 × x = 100 × 4

x = 100 × 4/80

x = 5 gallons of gas

Therefore, Jackson would use 5 gallons of gas to get to Mount Highmore.

Answer:

5 gallons of gas

Step-by-step explanation:

Answer:  He can make 3 batches of soup.

Starting with 10 pounds of tomatoes and taking out the number of pounds he sets aside for spaghetti sauce, 2.8, we have:

10-2.8 = 7.2 pounds left.

0.2 is read as "two tenths," so 7.2 = 7 2/10

We divide this remaining number of pounds by 2 2/5 for each batch of soup:

7 2/10 ÷ 2 2/5

Convert each to an improper fraction:

72/10 ÷ 12/5

Multiply by the reciprocal:

72/10 × 5/12 = 360/120 = 3

Hope this helps... Stay safe and have a great day/night!!! :D

Answer: Jarrah has to rake 25 bags.

Step-by-step explanation: Jarrah

Jarrah needs to get $159 dollars, right? Well since he already has $38, we just need to subtract 159 and 38. 159-38 is 121. (121 is how much heneeds  )Each bag raked costs $5, and 5 can't go into 121, so it's best to have more than less. Multiply 5 and 25, and you will get $125. That is more than enough, you cannot do 5x24 because it would be 120, which is too low. Therefore, Jarrah needs to rake 25 bags.

Answer:

Step-by-step explanation:

A) 12x² y⁵z = 2² * 3 * x² * y⁵ * z

150x⁶y⁵z    = 5² * 2 * 3 * x⁶ * y⁵ * z

66y⁹z   =   2 * 3 * 11 * y⁹ * z

GCF =  2 * 3 * y⁵ * z = 6y⁵z

B) 4x² - 40x + 100 = (2x)² - 2 * 2x * 10 + 10²

                             = (2x - 10)²

C) 81x² - 64 = (9x)² - 8²             {a² - b² = (a + b)(a - b)}

                   = (9x + 8)(9x - 8)

D) (a + b)² = a²+ 2ab + b²

E) a² - b² = (a + b)(a - b)

Answer:

Simplifying 4x2y + 12xy2 + 9y3 Reorder the terms: 12xy2 + 4x2y + 9y3 Factor out the Greatest Common Factor (GCF), 'y'. y(12xy + 4x2 + 9y2) Factor a trinomial.
