Answer:
50 hours
Step-by-step explanation:
if it takes 5 hours for 2 inches to fall, then you multiply 2 by ten to get 20, you do the same thing to the other half of the equation, or five, to get 50 hours.
The base of a right triangle is 2 meters greater than the height. If the area of the triangle is 100 m2, what are the dimensions of the base and the height?
Answer:
b = 15.2 m
h = 13.2 m
Step-by-step explanation:
The area of a right triangle is given by:
[tex] A = \frac{bh}{2} [/tex] (1)
Where:
b: is the base
h: is the height
If the base is 2 meters greater than the height we have:
[tex]b = h + 2[/tex] (2)
And if the area of the triangle is 100 m², the dimensions of the base can be found by entering equation (2) into (1):
[tex]100 m^{2} = \frac{(h + 2)*h}{2}[/tex]
[tex] 200 m^{2} = h^{2} + 2h [/tex]
[tex] h^{2} + 2h - 200 m^{2} = 0 [/tex]
By solving the above quadratic equation we have:
[tex] h = 13.2 m [/tex]
And by entering the above value into equation (2) we have:
[tex]b = 13.2 + 2 m = 15.2 m[/tex]
Therefore, the dimensions of the base and the height are 15.2 m and 13.2 m respectively.
I hope it helps you!
Paula is the student council member responsible for planning an outdoor dance. Plans include hiring a band and buying and serving dinner. She wants to keep the ticket price as low as possible to encourage student attendance while still covering the cost of the band and the food.
Question 1: Band A charged $700 to play for the evening and Band B changers $550 plus $1.50 per student.
Write a system of equations to represent the cost of the two bands.
Answer:
C(x) = $700 ;
C(x) = $550 + $1.50x
Step-by-step explanation:
Given that :
Band A = $700 to play for the evening
Band B = $550 plus $1.50 per student
Equation for cost of the 2 bands :
Let
cost function= C(x)
x = number of students
Band A:
C(x) = $700
Band B:
C(x) = $550 + $1.50x
The total cost for band A is y = 700 while the total cost for band B is y = 550 + 1.5x
A linear equation is of the form:
y = mx + b
where y, x are variables, m is the rate of change of y with respect to x, b is the y intercept.
Let y represent the total cost and x represent the number of students.
Band A charged $700 to play for the evening, hence:
For band A: y = 700
Band B changers $550 plus $1.50 per student, hence:
For band B: y = 550 + 1.5x
The total cost for band A is y = 700 while the total cost for band B is y = 550 + 1.5x

Answer:
7. (2,1) 8. (8,2)
Step-by-step explanation:
Step: Substitute4z−7foryin5y+3z=11:
5y+3z=11
5(4z−7)+3z=11
23z−35=11(Simplify both sides of the equation)
23z−35+35=11+35(Add 35 to both sides)
23z=46 Divide both sides by 23
x=2
Substitute2forxiny=4z−7:
y=4z−7
y=(4)(2)−7
y=1
Step: Solve2x+4y=24for x:
2x+4y+−4y=24+−4y(Add -4y to both sides)
2x=−4y+24
x=−2y+12
−2y+12forxin−2x+8y=0:
−2x+8y=0
−2(−2y+12)+8y=0
12y−24=0(Simplify both sides of the equation)
12y−24+24=0+24(Add 24 to both sides)
12y=24 Divide both sides by 12
y=2
Substitute2foryinx=−2y+12:
x=−2y+12
x=(−2)(2)+12

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
weight of 1 bucket of gravel = 7.05
weight of 20 buckets = 7.05 x 20
= 141 Kg
Hence, the weight of 20 buckets is 141 Kg.

Which triangle drfined by the given points on the coordinate plane is similar to the triangle illustrated?
Answer:D.) (-1, 1), (-1, 5), (-7, 1)
Step-by-step explanation:The length of the horizontal segment of the triangle graphed is 3. The length of the vertical segment of the triangle graphed is 2. Using the Pythagorean theorem, this makes the length of the missing side
2²+3²=c²
4+9 = c²
13=c²
√13 = c
This makes our side lengths 2, 3, and √13.
For choice A our vertices are (-1, 1), (-1, 4), (-6, 1).
This makes the length of the horizontal segment 5 and the length of the vertical segment 3. This makes the missing side length
5²+3²=c²
25+9=c²
34=c²
√34 = c
This is not proportional to the triangle drawn, so it is not similar.
The vertices of the triangle in option B are (-1, 1), (-1, 5), and (-6, 1). This makes the horizontal segment 5 units long and the vertical segment 4 units long. This makes the missing side length
4²+5²=c²
16+25=c²
41=c²
√41=c
These are not proportional to the triangle drawn, so the triangles are not similar.
The vertices of the triangle in choice C are (-1, 1), (-1, 4) and (-7, 1). This makes the length of the horizontal segment 6 and the length of the vertical segment 3. This makes the missing side length
3²+6²=c²
9+36=c²
45=c²
√45=c
3√5=c
These sides are not proportional to the sides of the triangle drawn, so the triangles are not similar.
The vertices of the triangle in choice D are (-1, 1), (-1, 5) and (-7, 1). This makes the length of the horizontal segment 6 and the length of the vertical segment 4. This makes the missing side length
6²+4²=c²
36+16=c²
52=c²
√52=c²
2√13=c
These sides are all twice as long as the sides of the triangle drawn; this means the triangles are similar.
