Answer:
Step-by-step explanation:
The information gives the Slope and y intercept of the line for stock A. At 9am, time = 0, the stock price is $15.11, the y intercept or b. The Slope of the line is 12 cents per hour, it is a positive Slope so it will rise from left to right.
The line in Slope form is
y= 0.12x+15.11
Stock B at noon, so 3 hours later, is $15.86 and is decreasing at a rate of 11 cents per hour.
We know the Slope is -0.11 and we know a point on its line is (3,15.86). From this we can solve for the y intercept by substituting the x and y values from the coordinate into the Slope equation.
15.86 = -0.11(3) + b
15.86 = -0.33 + b
Add 0.33 to both sides
16.19 = b so the equation of the line of stock B is y= - 0.11x + 16.19
Since we have two equations solved for y, we can set them equal to each other and solve for x
0.12x + 15.11 = - 0.11x + 16.19 add 0.11x - 15.11 to both sides
0.23x = 1.08 divide both sides by 0.23 to solve
x = 4.69565 to the nearest tenth 4.7 hours after 9am the two stocks will be the same price.

The triangles △ABC and △DEF are similar.
Which set of measurements prove that the two triangles are similar?
The two triangles are similar if the ratio of the corresponding sides are equal.
What is ratio?Ratio is a mathematical comparison of two or more quantities expressed as a fraction. A ratio can be expressed as a fraction, a decimal, or in the form of words. Ratios are used to compare items or quantities in a variety of different contexts, from mathematics and science to business and daily life. For example, a ratio of 2:1 indicates that for every two items, there is one of the same item.
This means that the ratio of side AB to side DE must be equal to the ratio of side BC to side EF, and the ratio of side AC to side DF must be equal to the ratio of the remaining sides.
For example, if side AB is 10 cm and side DE is 5 cm, then side BC must be 10 cm and side EF must be 5 cm for the two triangles to be similar. Similarly, if side AC is 8 cm and side DF is 4 cm, then the remaining sides must be 8 cm and 4 cm respectively.

Answer:
4 pairs.
Step-by-step explanation:
Shin guards-$8.58
7 pairs of socks-$4.29
Pays-$25.74
Let's express following equation:
[tex]$25.74=8.58+4.29x[/tex]
x will be the pairs of socks.
[tex]25.74-8.58=4.29x[/tex]

6. The base of a triangular field is three times its height. If the cost of cultivating the field
at 36 per hectare is? 486, find its base and height (1 hectare = 10000 m²).
Answer:
base = 519.62, height = 173.21 m
Step-by-step explanation:
Let the base and height of the triangle be represented by b and h respectively.
Thus,
b = 3h
Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height
For the given triangle,
area = [tex]\frac{1}{2}[/tex] x b x 3h
= [tex]\frac{3}{2}[/tex]bh
Area of the triangle = [tex]\frac{3}{2}[/tex]bh
To determine the number of hectares,
36 per hectare = 486
hectare = [tex]\frac{486}{36}[/tex]
= 13.5
numbers of hectares = 13.5
Area of the hectares = number of hectares x 10 000 m²
= 13.5 x 10 000
= 135000
Total area of the hectares = 135 000 m²
So that,
area of the hectares = area of the triangle
area of the triangle = [tex]\frac{3}{2}[/tex]bh
135 000 = [tex]\frac{3}{2}[/tex]bh
270000 = 3bh
bh = [tex]\frac{270000}{3}[/tex]
= 90000
bh = 90000
But, b = 3h
3h x h = 90000
3[tex]h^{2}[/tex] = 90000
[tex]h^{2}[/tex] = [tex]\frac{90000}{3}[/tex]
= 30000
h = [tex]\sqrt{30000}[/tex]
= 173.2051
h = 173.21 m
So that,
b = 3 x 173.2051
= 519.6153
b = 519.62
Therefore, the base of the triangle is 519.62 m, while the height is 173.21 m.
