Step-by-step explanation:
the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car used 25 liters on a 100 km trip at 100kph,about how many liters will it use on 1000 km trip at 64 kph?
Answer:
200 litres
Step-by-step explanation:
let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is
g = kd[tex]\sqrt{s}[/tex] ← k is the constant of variation
To find k use g = 25, d = 100 and s = 100, then
25 = k × 100 × [tex]\sqrt{100}[/tex] = k × 100 × 10 = 1000k ( divide both sides by 1000 )
0.025 = k
g = 0.025d[tex]\sqrt{s}[/tex] ← equation of variation
When d = 1000 and s = 64, then
g = 0.025 × 1000 × [tex]\sqrt{64}[/tex] = 0.025 × 1000 × 8 = 200

Answer:
√35i
Step-by-step explanation:
i is an imaginary number. It represents the square root of negative one. By pulling it out, we pull out the negative, and our answer uses the unit i. Because 35 cannot be simplified, we are done.
Answer:
We know that √-1 = i, where "i" is the imaginary unit
± √(-35) = ± √(35) i
± √(35) i is the right answer.Slove (3x-2)=(2x-1)/(2) show step by step
Answer:
x= 3/4
Step-by-step explanation:
[tex](3x - 2) = \frac{(2x-1)}{2}[/tex]
2(3x - 2) = (2x - 1)
6x - 4 = 2x -1
4x = 3
x= 3/4
Answer:
x=3/4
Step-by-step explanation:
Remove parentheses.
3x-2=\frac{2x-1}{2}3x−2=22x−1
Multiply both sides by 22.
6x-4=2x-16x−4=2x−1
Add 44 to both sides.
6x=2x-1+46x=2x−1+4
Simplify 2x-1+42x−1+4 to 2x+32x+3.
6x=2x+36x=2x+3
Subtract 2x2x from both sides.
6x-2x=36x−2x=3
Simplify 6x-2x6x−2x to 4x4x.
4x=34x=3
Divide both sides by 44.
x=\frac{3}{4}x=43

5200
Step-by-step explanation:
You know that she needs 14,500 for her first year
she has a total of 3000+6300 so far
To find out how much she needs just take the difference
14500-(3000+6300)=5200

Erick and Mia live the same distance from the park and decide to meet at the park one afternoon. The graphs show their distances from home over the same 30-minute period as they walked to the park. Each section of each graph represents 10 minutes.
Which statements are true ?
Choose all that apply.
Explain your answer.
A. Mia Returned to her house after 10 minutes.
B. Mia left her house 10 minutes before Erick left his house.
C. it took erick only 10 minutes to walk to the park.
D. Erick and Mia arrived at the park at the same time.
E. Erick walked the same distances as Mia during the last 10 minutes
Answer:
please continue i'm facinated on were this story goes
Step-by-step explanation:
From the graph, the correct options are given as,
B. Mia left her house 10 minutes before Erick left his house.
D. Erick and Mia arrived at the park at the same time.
E. Erick walked the same distances as Mia during the last 10 minutes.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The graphs show their distances from home over the same 30-minute period as they walked to the park.
From the graph,
It can be concluded that,
Both reach the park at the same time, as the termination point of the curve is the same.
The graph of mia starts after 10 minutes Erick, which implies Mia left her house 10 minutes before Erick left his house. And Erick walked the same distances as Mia during the last 10 minutes as the slope of the last segment of both curves is the same.

please help with an explanation.
Answer & Step-by-step explanation:
Let's have
C = Creepers
B = Balloons
1) 6C + 20B = 11.9
2) 2C + 15B = 6.05
Eliminate
16C + 20B = 11.9 x3
-2C + 15B = 6.05 x4
18C + 60B = 35.7
-8C + 60B = 24.2
10C/10 = 11.5/10
