Answer:
1.2 miles
Step-by-step explanation:
Morning laps = 3.5 laps
Evening laps = 1 lap
Total miles jogged = 5.4 miles
Total laps made = (3. 5 + 1) = 4.5 miles
Number of miles per laps covered :
Total miles jogged / number f lapses hugged around pond.
= 5.4 miles / 4.5
= 1.2 miles
Therefore, number of miles per round around the pond is 1.2 miles
The average mass of 5 man basketball team is 70Kg. Four of team members have a mass of 50kg, 62kg, 81kg, and 84kg What is the mass of the fifth player???? 15 POINTS!!!
Answer:
The mass of the fifth player is 73 kg
Step-by-step explanation:
Since the average mass of the 5 players is 70kg
what this mean is that the total sum of all the masses of the players is equal to the product of 5 and 70 kg
we have this as 5 * 70kg = 350 kg
So, by adding the masses of all the players, we get 350kg
Thus, for us to get the mass of the 5th player, we have to subtract the sum of the remaining 4 from the total 350kg
Mathematically, we have this as;
350 - ( 50 + 62+ 81 + 84) = 73 kg

The sides given relative to angle x is the adjacent and opposite side. We can find x by using a trig function.
When using the adjacent and opposite sides, we use tangent.
The tan. of an angle, in this case x, is the opposite side over the adjacent side.
tan x=6/15
x=arc tan 6/15≈22

So we're dealing with angles here.
So what we want to do is add the two angles and it =180
Here's the equation so it makes more sense:
[tex]A+B=180[/tex]
so we'd place in those numbers
[tex]53+31=180[/tex]
add the two angles together
[tex]53+31=84[/tex]
than we'd subtract from 180 getting the value of X

Gina subtracted 6 8 from 1 and found a difference of 2 8 . Which statement best describes the difference of 6 8 from 1 is 2 8 ? F The difference of 2 8 is not reasonable because 1 – 3 4 = 1 4 . G The difference of 2 8 is reasonable because 3 4 – 1 4 _ = 1 2 . H The difference of 2 8 is reasonable because 1 – 3 4 = 1 4 . J The difference of 2 8 is not reasonable because 3 4 – 1 4 = 1 2 .
Answer:
Statement H : The difference of 2/8 is reasonable because 1 – 3/4 = 1/4 .
Step-by-step explanation:
Given - Gina subtracted 6/8 from 1 and found a difference of 2/8 .
To find - Which statement best describes the difference of 6/8 from 1 is 2/8 ? Statement F : The difference of 2/8 is not reasonable because 1 – 3/4 = 1/4 .
Statement G : The difference of 2/8 is reasonable because 3/4 – 1/4 = 1/2 .
Statement H : The difference of 2/8 is reasonable because 1 – 3/4 = 1/4 .
Statement J : The difference of 2/8 is not reasonable because 3/4 – 1/4 = 1/2 .
Proof -
If we subtract 6/8 from 1 , we get
[tex]1 - \frac{6}{8} = \frac{8 - 6}{8} = \frac{2}{8}[/tex]
So, the difference is 2/8
It is reasonable.
So,
The correct statement is - Statement H : The difference of 2/8 is reasonable because 1 – 3/4 = 1/4 .
Reason -
As we can write
[tex]\frac{6}{8} = \frac{3}{4}[/tex] and [tex]\frac{2}{8} = \frac{1}{4}[/tex]
So,
either we subtract 6/8 from 1 or 3/4 from 1 , we get the same result because both the values are equal
So the correct statement is - H : The difference of 2/8 is reasonable because 1 – 3/4 = 1/4 .

A boat covers 25 km upstream and 44 km downstream in t hours. Also, it covers 15 km upstream and 22 km downstream in 5 hours. Find the speed of the boat in still water and that of the stream.
9514 1404 393
Answer:
boat speed: (7t -95)/(6t² -110t +500)
stream speed: (37t -345)/(6t² -110t +500)
Step-by-step explanation:
The relation between time, speed, and distance is ...
time = distance/speed
The boat speed (b) is added to the stream speed (s) going downstream. The stream speed is subtracted going upstream. The given relations tell us ...
25/(b-s) +44/(b+s) = t
15/(b-s) +22/(b+s) = 5
This gives us 2 equations in 3 unknowns, so we can only provide a solution in terms of one of the unknowns. Since we are asked for the speeds, they will be provided in terms of t.
Subtracting the first equation from 2 times the second gives ...
2(15/(b-s) +22/(b+s)) -(25/(b-s) +44/(b+s)) = 2(5) -(t)
5/(b-s) = 10 -t
5/(10 -t) = b -s
Substituting for b-s in the second equation gives ...
15/(5/(10-t)) +22/(b+s) = 5
30 -3t +22/(b+s) = 5
22/(b+s) = 3t -25
22/(3t -25) = b+s
Adding the equations for the sum and difference of speeds, we get ...
(b-s) +(b+s) = 5/(10-t) +22/(3t -25)
2b = (5(3t -25) +22(10 -t))/((10-t)(3t-25)) = (95 -7t)/((10-t)(3t-25))
b = (7t -95)/(6t² -110t +500)
Subtracting the equations for sum and difference of speeds, we get ...
(b+s) -(b-s) = 22/(3t -25) -5/(10 -t)
2s = (22(10-t) -5(3t -25))/((10-t)(3t-25))
s = (37t -345)/(6t² -110t +500)
__
The speed of the boat in still water is (7t -95)/(6t² -110t +500) km/h.
The speed of the stream is (37t -345)/(6t² -110t +500) km/h.
__
Note that these solutions only make sense for values of t between 25/3 and 345/37, approximately 8.33 < t < 9.32. For t=9 hours, the boat speed is 8 km/h and the stream speed is 3 km/h.

15 in.
What is the surface area of this solid?
square inches
Answer:
The answer is "[tex]\bold{1920 \ in^2}[/tex]".
Step-by-step explanation:
Please find the graph file.
Rectangular solid area:
Its region comprises four rectangles, each 15 for each case 14 in each.
The rectangle field is the formula [tex]A = lw[/tex]
The four rectangles are therefore covered by a zone: [tex]\to A = 4lw = 4 \times 15 \ in \times 14 \ in = 840 \ in^2.[/tex]
square Pyramids area:
The pyramids in both squares have 8 triangular facets.
Each triangle has a 15-inch basis with a 14-inch base.
The triangle zone formulation is [tex]A = \frac{1}{2}bh[/tex]
That's it. The 8 triangles area is [tex]\to A = 8 \times \frac{1}{2}bh = 4bh = 4 \times 15 \ in \times 18 \ in = 1080 \ in^2[/tex]
Total field surface:
Strong rectangular[tex]= 840 \ in^2[/tex]
Pyramids in the Square[tex]= 1080[/tex]
Overall area [tex]= 1920 \ in^2[/tex]
The number is [tex]1920\ in^2[/tex] for a total area.
The area of triangle QTU is 6 square units, and the area of triangle RSU is 6 square units. The dimensions in the figure below are labeled in units. What is the area of triangle STU in square units
Answer:
The area of a triangle is 1/2BH, or 1/2 times the base times the height.
If the area = 6, and B and H must both be whole numbers.
The area of the triangle ΔSTU is given by A = 12 units²
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the area of the triangle ΔSTU be represented as A
Now , the area of triangle ΔQTU is 6 square units, and the area of triangle ΔRSU is 6 square units
So , the base of the triangle ΔSTU = 6 units
The height of the triangle ΔSTU = 4 units
So , area of the triangle = ( 1/2 ) x Length x Base
On simplifying , we get
The area of triangle ΔSTU = ( 1/2 ) x 4 x 6
The area of triangle ΔSTU = 12 units²
Therefore , the value of A is 12 units²
Hence , the area of the triangle is 12 units²
