Answer:
194
Step-by-step explanation:
you would do 340 divided by 2 and that gets you 170 then you would subtract 24 from Rita and that is 146 so Rita drove 146 miles. then for Joel you add 170 +24 = 194. So Joel drove 194 miles.

Ten participants in a health study each ran a distance of 1 mile. The pulse rates of the participants were recorded before and after the run. The pre-run and post-run pulse rates, in pulses per minute (ppm), are shown in the table below.
Based on the data in the table, which statement is true?
The data given on the table about the ten participants in the health study shows that B. The post-run mean and median are the same value.
What is the post run mean?This can be found as:
= (87 + 95 + 96 + 101 + 110 + 104 + 100 + 101 + 90 + 96) / 10
= 98
What is the post run median?First order the pulses from smallest to largest:
= 87, 90, 95, 96, 96, 100, 101, 101, 104, 110
The two digits in the middle are:
96 and 100
The median will be:
= (96 + 100) / 10
= 98
In conclusion, option B is correct.

Step-by-step explanation:
Some boats were traveling up and down a river. A satellite recorded the movements of several boats.
A motor boat traveled -3.4 miles per hour for 0.75 hours. How far did it go? miles
A tugboat traveled -1.5 miles in 0.3 hours. What was its velocity? miles per hour
Answer:
3a) 2.55 miles
3b) -5 mi/h
Step-by-step explanation:
3a)
In this problem, we want to know the distance travelled by the boat.
For a boat in uniform motion (=constant speed), the distance travelled can be written as
d=vtd=vt
where:
d is the distance travelled
v is the speed
t is the time
For the motor boat in this problem, we have:
v = 3.4 mi/h (we ignore the negative sign, because it only refers to the direction, but here we are considering the speed, which is a scalar and has no direction)
t = 0.75 h is the time
Therefore, the distance travelled is
D= (3.4)(0.75 = 2.55 miles
3b)
The velocity of an object is the ratio between its displacement (change in position) and time taken.
Since velocity is a vector, it has both a magnitude and a direction: so in this case, we also have to consider the sign when expressing the velocity.
The velocity is given by:
v=\frac{d}{t}v=
t
d
where
d is the displacement
t is the time taken
For the tugboat in this problem,
d = -1.5 mi is the displacement
t = 0.3 h is the time taken
So, its velocity is
v=\frac{-1.5}{0.3}=-5 mi/hv=
0.3
−1.5
= -5 mi/h
And the negative sign indicates that the boat is moving in the negative direction.

What side lengths should be used to model a rectangle with an area of x2 3x – 10 square units? x – 5 and x 2 x – 2 and x 5 x and x 3 x 3 and x – 10
The dimension of the rectangle is (x + 5) and (x – 2). Then the correct option is B.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The area of the rectangle is x² + 3x – 10.
On factorization, we have
x² + 3x – 10
x² + 5x –2x – 10
x (x + 5) –2 (x + 5)
(x + 5) (x – 2)
We know that the area of a rectangle is given as
Area = Length × Width
x² + 3x – 10 = (x + 5)(x – 2)
On comparing, we have
The dimension of the rectangle is (x + 5) and (x – 2). Then the correct option is B.

PLEASE HELP
Answer:
see explanation
Step-by-step explanation:
the figure has 4 congruent sides and 4 right angles and is therefore a square, then
8x - 15 = 3x + 11 ( subtract 3x from both sides )
5x - 15 = 11 ( add 15 to both sides )
5x = 26 ( divide both sides by 5 )
x = 5.2
Answer:
It's a square
x = 26/5
Step-by-step explanation:
Well, since all the sides are equal (shown by the 3 lines in the sides) and all the angles are 90 degrees (show by the little squares in the corners), I believe the shape is a square.
Because the sides are equal, you would set up the equation by making the two expressions equal to each other:
3x + 11 = 8x - 15
The next step is to get the variable (x) on only one of the sides. You can do this by subtracting 3x from both sides or by subtracting 8x from both sides. I will subtract 3x here just so the new number can be positive, but either will work.
3x + 11 = 8x - 15
-3x -3x
0 + 11 = 5x - 15
Now, you isolate the x by adding 15 to both sides. Remember, whatever you do to one side, you must also do it to the other side of the equal sign.
11 = 5x - 15
+15 +15
26 = 5x
Lastly, get rid of the number in front of the x so that x is alone on a side of the equal sign. You do this by dividing both sides by 5.
x = 26/5
Now, you can either make this into a mixed number or a decimal or keep it how it is. I hope this helps :]

Answer:
x = 14
y = 7
z = 22
Step-by-step explanation:
x = # of cucumbers
y = # zucchini
z = # tomatoes
x + y + z = 43
2y = x or y = x/2
x + 8 = z
x + x/2 + x + 8 = 43
2x + x/2 = 35
4x + x = 70
5x = 70
x = 14
2y = 14
y = 7
14 + 8 = z
z = 22
Check if these variables are right:
14 + 7 + 22 = 43 ✔️
A lifeguard fills a pool with water at a constant rate. After 12 hour, 13 of the pool is filled. At this rate, what fraction of the pool is filled per hour?.
At the considered rate the fraction of pool that is filled per hour is 13/12
How to measure the rate of change of something as some other value changes?Suppose that we have to measure the rate of change of y as x changes, then we have:
[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where we have
[tex]\rm when \: x=x_1, y = y_1\\when\: x = x_2, y= y_2[/tex]
Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.
(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)
For the considered case, we can take time spent as difference of independent variable, and the amount of pools filled as the corresponding difference of the dependent variable.
in 12 hour time interval total 13 pools were filled.
That means
Rate of filling the pool is 13 pools per 12 hours or [tex]\dfrac{13}{12}[/tex] pools per hour.
Thus, at the considered rate the fraction of pool that is filled per hour is 13/12
