Answer:
Molar Mass Molar mass is defined as the mass of one mole of representative particles of a substance. By looking at a periodic table, we can conclude that the molar mass of lithium is 6.94g, the molar mass of zinc is 65.38g, and the molar mass of gold is 196.97g. Each of these quantities contains 6.02 × 1023 atoms of that particular element.

pls hurry I need help I will give brainiest also this question does not require a graph so I didn't send one
Answer:
(-4,-5) (-3,-3)
Step-by-step explanation:
[tex](-4,-5),(-3,-3)[/tex]
Coordinate GraphA coordinate graph is made up of two number lines that are perpendicular to each other. Axes are the names given to these numerical lines. Ordered pairs indicate positions on a coordinate graph. An ordered pair [tex](x,y)[/tex] is a coordinate graph location.Given equation is [tex]y=2x+3[/tex]
Put [tex](x,y)=(-4,-5)[/tex]
[tex]-5=2(-4)+3\\-5=-5[/tex]
Put [tex](x,y)=(-3,-3)[/tex]
[tex]-3=2(-3)+3\\-3=-3[/tex]
Put [tex](x,y)=(-1,0)[/tex]
[tex]0=2(-1)+3\\0\neq 1[/tex]
Put [tex](x,y)=(-1,-4)[/tex]
[tex]-4=2(-1)+3\\-4\neq 1[/tex]
So, [tex]\boldsymbol{(-4,-5),(-3,-3)}[/tex] lie on the graph [tex]y=2x+3[/tex]

x - 3.5 = -3.1
solve for x.
Answer:
0.4
Step-by-step explanation:
The numbers -3.5 and -3.1 have a difference in value of 0.4
An easy way to look at this is to remove the decimal points. 35 - 31 is equal to 4, so that would make the difference 0.4.
Because both numbers are negative, the x must be a positive.
Therefor, 0.4 - 3.5 = -3.1

There are 150 oranges, apples and pears in a box. The ratio of the number of oranges to the number of apples is 3:5 and the ratio of the number of pears to the number of apples is 2:5. Find the number of pears in the box.
Answer:
Pears: 30
Step-by-step explanation:
Constant:
3x + 5x + 2x = 150
10x = 150
x = 15
Multiply ratio with constant from above:
oranges : apples
3 * 15 : 5 * 15
45 : 75 ==> 45 oranges: 75 apples
pears : apples
2 * 15 : 5 * 15
30 : 75 ==> 30 pears: 75 apples
Check:
45 oranges + 75 apples + 30 pears = 150 fruits

You and your friends are having a race, but since you are faster than he is, you decide to give him a head start. He starts 10 m In front if the starting line, while you start on the starting line. You run at 6 meters/ second, while your friend runs at 5.5 meters/ second. After how many seconds will you and your friend be same distance from the starting line?
Answer:
the number of seconds that you and your friend would be have the similar distance from the starting line is 20 seconds
Step-by-step explanation:
The computation of the number of seconds that you and your friend would be have the similar distance from the starting line is shown below:
As we know that
Speed = Distance ÷ Time
SO,
Time = Distance ÷ speed
= 10 meters ÷ difference in speed
= 10 meters ÷ (6 meters per second - 5.5 meters per second)
= 10 meters ÷ 0.5 meters per second
= 20 seconds
hence, the number of seconds that you and your friend would be have the similar distance from the starting line is 20 seconds

Mike hiked to a lake in 4.5 hours at an average rate of 2

5
miles per hour. Pedro hiked the same distance at a rate of 2
3
5
miles per hour. How long did it take Pedro to reach the lake? Round to the hundredths place.
It took Pedro
hours to reach the lake.
Answer:
It took Pedro 3.81 hours to reach the lake.
Step-by-step explanation:
Time taken by Mike to hike a lake = 4.5 hours
Average rate of Mike while hiking the lake = [tex]2\frac{1}{5}\ miles/hr[/tex]
Formula for distance can be seen as:
[tex]Distance = Speed\times Time[/tex]
Distance traveled by Mike = [tex]4.5 \times 2\frac{1}{5} = 4.5\times \frac{11}{5} = 9.9\ miles[/tex]
Rate of Pedro while hiking the same distance = [tex]2\frac{3}{5}\ miles/hr = \frac{13}{5}\ miles/hr[/tex]
Given that, Pedro also travels the same distance.
And we have to find the Time.
[tex]Time = \dfrac{Distance}{Speed}[/tex]
[tex]Time = \dfrac{9.9}{\frac{13}{5}}\\\Rightarrow Time = \dfrac{9.9\times 5}{13} = \bold{3.81\ hours}[/tex]
It took Pedro 3.81 hours to reach the lake.

Here are six number cards -4,-2,-1,5,6,8
arrange the cards into three pairs with the same total
Answer:
5 and 6 and -1
6 and 8 and -4
5 and 8 and -2 and -1
Step-by-step explanation:
They all add up to 10.
The trick is to first figure out if you can combine 5 6 or 8 together, then use the negative numbers to subtract as needed to reach you number. If you add 5 and 6, that is 11, but -1 can make 10. When you add 8 and 6, that is 14. But good thing you have the -4 to make 10. You start with the smallest number found from adding together two numbers from the positive pile like 5 and 6.
You can make other combinations as well. 11 could work too.
please click heart to give thanks :) c
The pairs of cards are (-4, 8), (-1, 5) and (-2, 6) respectively.
What is addition?Addition is a mathematical operation which used to count the things when are together. The addition of two positive integers are greater than both of them while for negative integers it is less than both of them.
Given that,
The different cards having numbers on them are as below,
-4, -2, -1, 5, 6, 8.
In order to select them into three pairs having the same sum make the pair as follows,
Add each positive number to each of the negative numbers and then select the pair of numbers having the same sum.
Thus, it is obtained as,
-4 + 8 = 4
-1 + 5 = 4
-2 + 6 = 4
Hence, the required pairs of cards are (-4, 8), (-1, 5) and (-2, 6) respectively.
