Find two fracrions in between 2/7 and 3/7 whose numerator and denominator are whole numbers
Answer:
7/21 and 8/21
Step-by-step explanation:
2/7 can be also written as 6/21 and 3/7 as 9/21
so, fraction in between 6/21 and 9/21 is 7/21 and 8/21
The two fraction in between 2/7 and 3/7 are 7/21 and 8/21.
Here,
We have to find two fraction in between 2/7 and 3/7.
What is Whole number?
The numbers which is start from 0 (zero) are called whole number.
Now,
The fraction 2/7 can be also written as,
[tex]\frac{2*3}{7*3} = \frac{6}{21}[/tex]
And, The fraction 3/7 can be also written as,
[tex]\frac{3*3}{7*3} = \frac{9}{21}[/tex]
Hence, we get;
[tex]\frac{6}{21} , \frac{7}{21} ,\frac{8}{21} ,\frac{9}{21}[/tex]
Therefore, The two fraction in between 2/7 and 3/7 are 7/21 and 8/21.

Find the slope of 10y = 7x + 5.
Round to the third.
Answer:
0.7
Step-by-step explanation:
10y = 7x + 5
Divide both sides by 10.
y = 7x/10 + 5/10
y = 0.7x + 0.5
On a straight line of the form y = kx + m, k is the slope of the line.
In our line, y = 0.7x + 0.5, k is 0.7. Thus, the slope of our function is 0.7
Answer: 0.7

Scientists were monitoring the temperature of a solution. It began at 63°F, and the temperature changed by 8°F over the course of 6 hours.
The final temperature of the solution was a minimum of __°f and a maximum of __°f
Answer:55&71
Step-by-step explanation: The 6 hours is unnecessary info. 63-8=55 and 63+8=71.
The final temperature have the minimum should be 55 and the maximum should be 71.
Calculation of the minimum & maximum:Since It began at 63°F, and the temperature changed by 8°F over the course of 6 hours.
So here the minimum should be
= 63-8
= 55
And, the maximum should be
= 63 + 8
= 71

Answer:
33. D.1/3
34. D. y= x+4
35. Slope= -2/3 Y-intercept= -6
Step-by-step explanation:
For number 33. D. 1/3 is the correct answer.
Start at the point (0,2) Then, Go up 1 and Right 3.
As a result, you land in the point (3,3) This proves that the slope is 1/3.
Note: the line is increasing and going upwards, so the slope is positive.
For number 34. D. y=x+4 is the correct answer.
When writing an equation of a line, the correct format is y=mx+b. We are given both m and b. So all we have to do is plug these values into the equation y=mx+b. As a result, we get y=1x+4, which also means y=x+4
For number 35. The Correct answer is: Slope= -2/3 Y-intercept= -6
For this question I can't see all the answer choices but I know that the Slope is -2/3 and the Y-intercept is -6. Here's why: First you need to transform the equation 2x+3y=-18 into y=mx+b format. To do this, subtract -2x from both sides of the equation and you are left with 3y=-18-2x. You can flip -18 and -2x which makes the equation 3y=-2x-18. The next step is to divide both sides of the equation by 3, which gives you y=-2/3x-6. This means Slope= -2/3 and Y-intercept= -6

EASY MATH QUESTION! WILL GIVE BRAINLIEST! (MUST EXPLAIN HOW YOU GOT YOUR ANSWER!) By the end of the first quarter of a football game, Gary had gained 42 yards and had lost 9 yards. Gary lost an additional 18 yards and gained 58 yards in the second quarter. Write an equation to represent his total yardage for the first half of the game.
Answer:
+73 yards.
Step-by-step explanation:
Since we have the first two quarters, we can simply work out the yardage for each game and add them together to get the total.
42-9 = 33 (first game)
58-18 = 40 (second game)
Therefore his total yardage was +73.

If pennies and dimes come in rolls of 50 coins each, while nickels and quarters come in rolls of 40 coins each, how many dollars is 5 rolls of pennies, 6 rolls of nickels, 7 rolls of dimes, and 8 rolls of quarters?
We will have $129.5 of 5 rolls of pennies, 6 rolls of nickels, 7 rolls of dimes, and 8 rolls of quarters.
Given:
Pennies ( $0.01 ) come in rolls of 50 coins each,
Dimes ( $0.1 ) come in rolls of 50 coins each,
Nickels ( $0.05 ) come in rolls of 40 coins each,
and Quarters ( $0.25 ) come in rolls of 40 coins each.
5 rolls of pennies, 7 rolls of dimes, 6 rolls of nickels, 8 rolls of quarters came.
Thus,
[tex]\begin{aligned} \rm{Total\; Value}&=0.01 \times 50 \times 5 + 0.1 \times 50 \times 7 + 0.05 \times 40 \times 6 + 0.25 \times 40 \times 8\\&= 2.5 + 35 + 12 + 80\\&= \$129.5 \end{aligned}[/tex]
