Answer:
Fourth option
Step-by-step explanation:
We know that A and B are rational numbers because they can be written as the quotient of two integers. Therefore, that eliminates the first and third options because they state that (at least) one of the numbers is irrational but we know that both are rational, hence, they are incorrect. The second option is incorrect because A · B = [tex]\frac{mn}{pq}[/tex], not [tex]\frac{mp + nq}{pq}[/tex], therefore, the correct answer is the fourth option.
Marrisa added 1.56 and 13.47. She got 29.07. What mistake could Marrisa have made? She forgot to move the decimal point to the left after she added. She lined up the front numbers instead of the decimal places. She lined up the last numbers instead of the decimal places. She didn’t carry correctly between place values.
without an explanation your answer is (B) She lined up the front numbers instead of the decimal places.
if you need an explanation here:
________________________________________
For a problem with a decimal in the numbers, you ALWAYS have to line them up or your answer will be incorrect.
She should have put: 13.47
+ 1.56
15.03
therefore, 15.03 would have been her correct answer. :-)

Find the inverse of the following function g(x) = 2x+10/4
Answer:
Step-by-step explanation:
To find the inverse of the function you need to swap x and y
g(x)=y so therefore if you switch x and y, you get
x= 2y+ 10/4
Next, you need to get all of the values on the y side over to the x side. To do this you need to subtract 10/4 from the y side of the equation.
x-10/4=2y+10/4-10/4
The end product of this should be... (This is not your answer)
x-10/4=2y
Now you need to get rid of the 2 on the y side. To do this you need to divide both sides of the equation by 2
2/x-10/4=2y/2
So your answer is...
x-10/4 over 2 = y
OR
2/x + 5/4 = y

Answer:
[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex]
Step-by-step explanation:
By hit and trial method,
Given series of fractions will be,
[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex]
Since, [tex]\frac{3}{6}=\frac{3\times 1}{3\times 2}[/tex]
[tex]=\frac{1}{2}[/tex]
[tex]\frac{7}{14}=\frac{7\times 1}{7\times 2}[/tex]
[tex]=\frac{1}{2}[/tex]
[tex]\frac{29}{58}=\frac{29\times 1}{29\times 2}[/tex]
[tex]=\frac{1}{2}[/tex]
Therefore, [tex]\frac{1}{2}=\frac{1}{2}=\frac{1}{2}[/tex] is the reduced form of the fractions.
[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex] will be the answer.
Two times the complement of an angle is 23 less than the supplementary of the angle. What is the measure of the angle?
Answer:
Step-by-step explanation:
Let the angles be x and y
If the two angles are complementary then their sum is 90 i.e x+y = 90
x = 90-y
If the two angles are supplementary, then their sum is 180 i.e x+y = 180
x = 180-y
If two times the complement of an angle is 23 less than the supplementary of the angle, this is written as;
2(90-y) = (180-y)-23
180-2y = 157-y
-2y+y = 157-180
-y = -23
y = 23
Hence the angle is 23°

In a bag there are 3 red marbles, 2 yellow marbles, and 1 blue marble. What are the odds of a yellow marble being selected on the first draw? CHOICES ------> ( 4:2 1:5. 3:3. 2:4) SOS
Answer:
1:3
Step-by-step explanation:
To find the probability of selecting a certain type of item from a collection, simply divide the number of items of that type by the total number of items.
There are 3 + 2 + 1 = 6 marbles in total. There are 2 yellow marbles, so the probability of choosing a yellow marble on the first draw is 2/6. This can be further simplified to 1:3.
Answer:
i would say 2:4
Step-by-step explanation:
think about them as basketball teams
The yellow team has two players
the mix team has 4 players
so the game is 2 players on 4 players

19. What is the coordinate of the midpoint of the segment formed by the two points you found in Exercises 17 and 18?
Please explain
Answer:
0
Step-by-step explanation:
To find the coordinate of the midpoint of segment QB, first, find the distance from Q to B.
QB = |4 - 8| = |-4| = 4
The coordinate of the midpoint of QB would be at ½ the distance of QB (½*4 = 2).
Therefore, coordinate of the midpoint of QB = the coordinate of Q + 2 = 4 + 2 = 6
OR
Coordinate of B - 2 = 8 - 2 = 6
Coordinate of the midpoint of QB = 6
Coordinate of W = -8
Coordinate of A = 0
distance from W to A (WA) = |-8 - 0| = |-8| = 8
The coordinate of the midpoint of WA would be at ½ the distance of WA = ½*8 = 4.
Therefore, coordinate of the midpoint of WA = the coordinate of W + 4 = -8 + 4 = -4
Or
Coordinate of A - 4 = 0 - 4 = -4
Coordinate of the midpoint of WA = -4
Now, let's find the midpoint between the two new coordinates we have found, which are -4 and 4
Distance of the segment formed by coordinate -4 and 4 = |-4 - 4| = |-8| = 8
Midpoint = ½*8 = 4
Coordinate of the midpoint = -4 + 4 = 0
Or
4 - 4 = 0
Solve for x: 6x + one over four(4x + 8) > 12 Im lost please help asap
Answer:
[tex]x > \frac{10}{7} [/tex]Step-by-step explanation:
[tex]6x + \frac{1}{4} (4x + 8) > 12[/tex]
Expand the terms in the bracket
That's
[tex]6x + x + 2 > 12 \\ 7x + 2 > 12[/tex]
Subtract 2 from both sides of the inequality
That's
[tex]7x + 2 - 2 > 12 - 2 \\ 7x > 10[/tex]
Divide both sides by 7
That's
[tex] \frac{7x}{7} > \frac{10}{7} [/tex]
We have the final answer as
[tex]x > \frac{10}{7} [/tex]

Mario travels 180 miles in 2.5 hours of Mario travels at the same right how far can Mario travel in 12.5 hours
Answer:
900 miles
Step-by-step explanation:
well if you have 12.5 and you divide it by 2.5 you get 5. I do this because you need to find out how many time 2.5 goes into 12.5 so you can then multiply 180 by that number. 180*5=900

True or False: by using the additive inverse property -64 - (-17) can be rewritten as -64 + 17
Step-by-step explanation:
Additive inverse is when you have a positive number, for example, and it becomes a negative.
Example: 8
The additive inverse of 8 is -8.
So the answer is false.
-64+17 and -64-(-17) is an example of communative property.

Ari is jogging at an average rate of 2.25 meters per second. Find the time it will take him to jog 270 meters.
Answer:
120 seconds/2 minutes
Step-by-step explanation:
divide the distance (270 m) by the rate (2.25 m/s) and you have 270/2.25 = 120 seconds, or 2 minutes.
It will take Ari 120 seconds to jog 270 meters.
To find the time it will take Ari to jog 270 meters at an average rate of 2.25 meters per second, we can use the formula:
Time = Distance / Rate
where:
Distance = 270 meters
Rate = 2.25 meters per second
Time = 270 meters / 2.25 meters per second
Time = 120 seconds
Therefore, it will take Ari 120 seconds to jog 270 meters.
