As for the answer, the length of the three sides was x=4.
Let [tex]x[/tex] be the length of the two sides that are the same.
Then the third side would be 2x-3
The perimeter of the triangle will come from adding all of the sides together and setting it equal to the value given, 13.
That is,
x + x + (2x-3)=13
4x-3=13
4x=13+3
4x=16
x=4
The length of each of the common sides is 4, making the third side 5, to get a total perimeter of 13.
What are two sides of a triangle?The hypotenuse of a right-angled triangle is its longest side, the base is its lower side, and the perpendicular, which stands next to the right angle, is its standing line.

a swimming pool has two pipes coming in. one fills the pool in four hours, the other in six hours. an outlet pipe empties the pool in five hours. the outlet pipe is accidentally left open. in how many hours is the pool full?
The pool is full for 4 hrs.
Add the rates of filling of the 2 filling pipes and
subtract the rate of draining of the emptying pipe;
1st pipe's rate: ( 1 pool filled ) / ( 3 h);
2nd pipe's rate: ( 1 pool filled ) / ( 6 h );
3rd pipe's rate of emptying: ( 1 pool emptied ) / ( 4 h);
Let t = the time in hrs to fill the pool with all 3 pipes open
1/3+16-1/4 = 1/t;
Multiply both sides by 24t;
t = 4 hrs

A cube has a volume of 197 meters cubed (197 m3) What is the approximate value of one edge of the cube? The approximate value of one edge of the cube is meters. Round your answer to the nearest hundredth. What is the approximate area of one face of the cube? The approximate area of one face of the cube is meters. Round your answer to the nearest hundredth.
The edge length and area of the face of the cube are 5. 82 meters and 203 square meters respectively
How to determine the valueThe formuka for the volume of a cube is expressed as;
Volume = a^3
Where 'a' is the length of it's edge
From the information given, we have that the volume of the cube has a value of 197 cubic meters.
Now, substitute the value of the volume
We have;
197 = a^3
Take the cube root of both sides
a = 5. 82 meters
The formula for area of the face of a cube is given as;
Area = 6a ^2
Area = 6(5.82)^2
Area = 6(33. 85)
Area = 203 square meters
Thus, the edge length and area of the face of the cube are 5. 82 meters and 203 square meters respectively

1) If, while training for a marathon, you ran 64 miles in 2 4/5 months, how many miles did you run each month? (Assume you ran the same amount each month) Write your answer as a whole number, proper fraction, or mixed number in simplest form.
Answer:
22 6/7 miles========================
GivenTotal distance is 64 miles,Total time is 2 4/5 months.SolutionIn order to find the distance you run each month you need to divide the total distance by the number of months:
64 : 2 4/5 = 64 : 14/5 = 64 * 5/14 = 32*5/7 = 160/7 = 22 6/7 milesAlejandro and some friends are going to the movies. At the theater, they sell a bag of popcorn for $3.50 and a drink for $4.

Total cost, 3 bags of popcorn and 8 drinks:______
Total cost, p bags of popcorn and d drinks:______
Answer:
Step-by-step explanation:
Using a proportional relationship, the costs are given as follows:
3 bags of popcorn and 8 drinks: $42.05.p bags of popcorn and d drinks: C(p,d) = 3.35p + 4d.What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
A proportional relationship may also involve multiple variables, as is the case in this problem, in which the cost is a function of the number of bags of popcorn p and the number of drinks d.
The constants are the prices of each product, hence the function for the total cost of p bags of popcorn and d drinks is given by:
C(p,d) = 3.35p + 4d.
Hence, for 3 bags and 8 drinks, the cost is:
C(3,8) = 3.35(3) + 4(8) = $42.05.

If she starts with 6 miles today and add 2 miles each day to her distance until she achieves her goal and then she has to run 176 miles in total to achieve her 26 miles goal.

0.82, 45/50 ,80%
14. The numbers ordered from lowest to highest are
Answer:
Step-by-step explanation:
0.82, 45/50 ,80%
14. The numbers ordered from lowest to highest are
0.82 = 0.82
45/50 = 0.9
80% = 4/5 = 0.8
80%0.8245/50A particular antibiotic is eliminated from the blood with a half-life of 16 hours. how many hours does it take for 100-milligram dose to decrease to 30-milligrams in the blood?
Using the decay formula, the particular antibiotic with half-life of 16 hours, will decrease to 30-milligrams in the blood after 27.79 hours.
We can use the decay formula to solve the problem:
A(t) = A(0) . (0.5)^(t/T)
Where:
A(t) is the remaining quantity at time t
A(o) is the initial quantity
t is the time interval
T is the half-life rate
In the given problem:
A(0) = 100 milligram
T = 16 hours
A(t) = 30 milligram
We need to find t such that the remaining quantity of this antibiotic is 30 mg.
Substitute the given parameters into the formula:
A(t) = A(0) . (0.5)^(t/T)
30 = 100 . (0.5) ^(t/16)
Taking the logarithm:
log (30) = log [100 . (0.5) ^(t/16)]
Use the logarithm property, log(A.B) = log A + log B
log (30) = log (100) + log [(0.5) ^(t/16)]
Use the logarithm property, log(Aⁿ) = n.log A
log (30) = log (100) + (t/16) . log (0.5)
log (30) = 2 + (t/16) . log (0.5)
(t/16) . log (0.5) = log (30) - 2
t/16 = 1.737
t = 1.737 . (16) = 27.79 hours

In reality, the lateral face VAB is an isosceles triangle with a 14-length base and 25-length legs. This triangle's altitude must cut over angle V and the base, forming a right triangle with a hypotenuse that is 25 inches long and a short leg that is 7 inches long. We can calculate the altitude, which is also the slant height of the pyramid, using the Pythagorean theorem.
s.h. = alt. = √(252 - 72) = 24
Now, by adding the pyramid's height and half of its base, we may utilize this slant height as the hypotenuse of another right triangle.
We look at a regular octagon to identify half the base. You'll see that four of the sides are horizontal or vertical, while the other four are at an angle of 45 degrees to the first four. So, in this example, 14 + 28/2 = 14 + 142, the distance between parallel sides of a regular octagon would be equal to s + 2s/2.
hence, the base's half would equal 7 + 72.
The height of the pyramid and the dihedral angle with the base are both provided by this right triangle.

number of groceries, water, and toys in each box.
a) How many boxes are needed? b) What are the contents of each box?
160 boxes needed to pack these items
Therefore contents in each box have 4 bags of groceries, 2 cases of bottled water, and 5 toys.
Given no of groceries bags = 640
number of cases of bottled water = 320
number of small toys = 800
We have to find out how many boxes are needed and the contents of each box.
(i) How many boxes are needed:
To do this we need to find the greatest common factor of these three items
as
640 - 2⁷ * 5
320 - 2⁶ * 5
800 - 2³ * 5²
GCF = 2⁵ * 5 = 160
Therefore 160 boxes needed to pack these items
(ii) Contents of each box:
No of bags of groceries in each box = 640 / 160 = 4
No of cases of bottled water = 320 / 160 = 2
No of toys in each box = 800 / 160 = 5
Therefore, contents in each box have 4 bags of groceries, 2 cases of bottled water, and 5 toys.
