Is this your question?
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour. His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour. (the question is What is Mila's average swimming speed?)
Answer:
Mila's average swimming speed is 34.44 m/min.
Logan's average speed is 2.25 kilometers per hour.
Step-by-step explanation:
Given:
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.
His swimming partner, Mila, swam 2/3 of Logan's
To Find:
What is Logan's average swimming Speed?
Solution:
The relationship between speed, distance, and time is easily remembered when you consider that speed is written in terms of units of distance per units of time. (miles per hour, or kilometers per hour, for example) "per" means "divided by".
[tex]\left[Speed=\frac{Distance}{Time} \right][/tex]
[tex]\left[speed = (750 m)/(1/3 h) = 2250 m/h = 2.25 km/h\right][/tex]
Logan's average speed is 2.25 kilometers per hour.
-------------------------------------------------------------------------------------------------------------
Given:
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.
His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour
To find:
What is Mila's average swimming speed?
Solution:
The distance swam by Logan = 750 m
The distance swam by Mila = 2/3 of Logan's distance = 2/3 x 750 = 2 x 250 = 500
The time taken by Mila to swim 500 m = 1/4 of an hour = 1/4 x 60 = 15 Minutes [since 1 hr = 60 mins]
We know the formula as:
[tex]\left[Speed=\frac{Distance}{Time} \right][/tex]
Now, substituting the values in the formula above to find the speed of swimming of Mila,
The average swimming speed of Mila = [tex]\frac{500m}{15mintues}[/tex][tex]=33.34m/min[/tex]
Therefore, Mila's average swimming speed is → 34.44 m/min.

do logarithmic functions have horizontal asymptotes?
9514 1404 393
Answer:
not generally
Step-by-step explanation:
The basic log function has a vertical asymptote where its argument is zero. It has a positive slope for all positive arguments. It tends to infinity as the argument tends to infinity. There is no horizontal asymptote.
__
A log function can be made part of a larger expression in a way that would give the expression a horizontal asymptote. For example, the function ...
f(x) = 1/log(x)
has a horizontal asymptote at f(x) = 0. (This asymptote is approached very slowly.)

The hypotenuse of a right triangle is 35 in. One leg of the triangle
measures 21 in. What is the length, in inches, of the other leg of
the triangle?
Answer:
28 in

Where c is the hypotenuse of the right angle triangle ,and a and b the other sides. Just substitute the values and get your answer.
Ms. Sublett's math class is putting three numbers (0.3, 1/4, and 20%) in order from least to greatest. What order should the numbers be from least to greatest?
Answer:
least to greatest
20% , 1/4, 0.3
20% = 1/5 = 0.2
0.3 = 3/10 = 30%

Answer:
11.7
Step-by-step explanation:
Step 1: Our output value 39.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 39 = 100%.
Step 4: Similarly, x = 30%.
Step 5: This results in a pair of simple equations:
39 = 100%(1)
x = 30%(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
39/x = 100%/30%
Step 7: Again, the reciprocal of both sides gives
x/39 = 30/100
------> x = 11.7
Therefore, 30% of 39 is 11.7

Answer:
Reflexive property
Step-by-step explanation:
The reflexive property of congruence states that any geometric shape is congruent to itself.
Answer:
C) Symmetric Property
Step-by-step explanation:
The Symmetric Property states that If A is congruent to B, then B is also congruent to A. This implies that the congruence is symmetric.
Khan Academy also states that:
When a relation has a symmetric property, it means that the if relation is true between two things, it is true in either order. If VW ≅ XY, then XY ≅ VW.
Therefore, the correct answer is C) Symmetric Property.

Solve the formula c = 5p + 215 for p
Answer:
1/5c -43 =p
Step-by-step explanation:
c = 5p + 215
Subtract 215 from each side
c-215 = 5p +215-215
c-215 = 5p
Divide each side by 5
c/5 -215/5 = 5p/5
1/5c -43 =p

The diagram shows a trapezium PQRS.

Formula in finding the trapezoid's area:
USE THIS FORMULA!: 1/2 × altitude × (base [tex]_{1}[/tex] + base [tex]_{2}[/tex])(note: altitude is also known as the height)
Area = 1/2 × 5 × (6 + 8)
A = 1/2 × 5 × 14
A = 2.5 × 14

Parallel with a slope of 5/6
Perpendicular with a slope of 1/4 and
Perpendicular with a slope of 1/4
Neither, slopes are 1/4 and 5/6
O
Neither, slopes are 3/10 and 1/2
Answer:
Neither, slopes are 1/4 and 5/6
Step-by-step explanation:
Let's find the slope for Line 1: (-3,-1) and (-7,-2)
m1 = (-2+1)/ (-7+3)
= -1/-4
=1/4
Line 2: (2.-1) and (8,4)
m2= (-4+1)/ (8-2)
= -3/6
= - 1/2
These slope values are not the same, so the lines are not parallel. The slope values are also not negative reciprocals, so the lines are not perpendicular. Then the answer is
Neither, slopes are 1/4 and 5/6
