Answer:
793 liters of washing fluid is needed
Step-by-step explanation:
step 1
Find the slant height of the triangular faces of pyramid
we know that
The lateral area of a square pyramid is equal to the area of its four triangular faces
so
![LA=4[\frac{1}{2}bl]](https://tex.z-dn.net/?f=LA%3D4%5B%5Cfrac%7B1%7D%7B2%7Dbl%5D)
where
b is the base of triangle (is the same that the length of the square base)
l is the slant height
To find out the slant height we need to apply the Pythagorean Theorem
so
we have
substitute
step 2
Find the lateral area of the pyramid
we have
substitute
![LA=4[\frac{1}{2}(35.42)(27.96)]](https://tex.z-dn.net/?f=LA%3D4%5B%5Cfrac%7B1%7D%7B2%7D%2835.42%29%2827.96%29%5D)
step 3
Find out how much window washing fluid is needed
we know that
2 L of washing fluid cover 5 square meters
so
using proportion
Round up
793 liters of washing fluid is needed
Answer:
y=-3/4x
Step-by-step explanation:
the form is "y=mx(+/-b). m is slope. b is y-intercept.
Answer:
Step-by-step explanation:
9). It's given in the triangle → Two angles are equal in measure
Therefore, by the definition of an isosceles triangle, opposite sides of the equal angles are equal in measure.
x = 12
10). Two sides of the given triangles are equal in length.
By the definition of an isosceles triangle, opposite angles of the equal sides of the triangle will be equal in measure.
Therefore, y = 55°
By the triangle sum theorem,
x° + y° + 55° = 180°
x° + 55° + 55° = 180°
x = 180 - 110
x = 70°
11). By the definition of an isosceles triangle, opposite sides of the equal angles will be equal in measure.
x + 3 = 12
x = 9
12). By the definition of an isosceles triangle, opposite angles of the equal sides of the triangle will be equal in measure.
m∠2 = 53°
x + 65 = 53
x = 53 - 65
x = -12
I believe that it is 425 minutes because 17+(.11×425) is 63.75 and so is .15×425.
Some advantages of using the numerical values are that it sums up all the data in a simple way (if you use the correct number for the data). If you are trying to communicate information about all the data that has been collected in a simple way (ex: grade), it makes sense to use numbers. Another advantage is that numerical data is relatively simple to find, when compared to representing the data visually.
Advantages of using visual representations are that you can see patterns/tendencies more easily within the data when there are pictures/organization of the data. Visual representations also give a broader perspective of the entire data set, instead of just using one number. You can see how data is represented from the beginning to the end.
The last question is an opinion question, but my preference is visual.
