1) A car moves with a speed of 40 km/h for 15 mins and then with a speed of 60 km/h for next 15 mins . The total distance covered by the car is : _________
(a) 100km. (b) 25km
(c) 15km. (d) 10km
• Don't spam
• Need Genuine Answer with Explanation .
Answer:
25 km
Explanation:
Distance = speed * time
We have change time which are given in minutes to hour. As the speed is mentioned in kilometre per hour.
For part A:
[tex]\rightarrow Distance = speed * time[/tex]
[tex]\hookrightarrow Distance = 40 * \frac{15}{60}[/tex]
[tex]\hookrightarrow Distance = 10[/tex] km
For part B:
[tex]\rightarrow Distance = speed * time[/tex]
[tex]\hookrightarrow Distance =60 * \frac{15}{60}[/tex]
[tex]\hookrightarrow Distance = 15[/tex] km
Total distance covered:
part A + part B
10 km + 15 km
25 km
25 km
Solution :-Speed of the car in first 15 mins ,
The car is moving in the speed of 40 km/h for 15 mins.
Distance covered = speed × Time taken Distance covered = 240 × 15/60 = 10 kmSpeed of car in next 15 mins ,
again ,
distance covered = 60 × 15/60 = 15kmnow , total distance covered = ( 10 + 15 ) km = 25 km

What is an equation of the line that passes through the points (4,4) and (8.1)
Answer:
y = - 3/4x + 7Step-by-step explanation:
Use both points and find the slope:
m = (1 - 4) / (8 - 4) = - 3/4Find the line, using point-slope form and point (4, 4):
y - 4 = - 3/4(x - 4)y - 4 = - 3/4x + 3y = - 3/4x + 7if y = 1x + 0 then what i the slope?

Answer:
$132
Step-by-step explanation:
[] First, we will set up an equation for Ross.
-> We will use slope-intercept form (see attached)
-> The slope:
[tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1} }[/tex] = [tex]\frac{81-40.5}{6-3}[/tex]=[tex]\frac{40.5}{3}[/tex]=13.5
-> The y-intercept:
y = 13.5x + b
(81) = 13.5(6) + b
81 = 81 + b
0 = b
-> Final equation:
y = 13.5x
-> For 8 hours, we will plug in 8 as the x.
y= 13.5(8)
y = $108
[] Joey earns 3 dollars more,
y = (13.5 + 3)x
-> Now we will plug 8 into the equation as x,
y = $132

Answer:
A = 6
B = 10
Step-by-step explanation:
[] Let's look at the system again:
[tex]\left \{ {{Ax+By=38} \atop {2Ax-By=16}} \right.[/tex]
[] They give us a set of x and y values, (3, 2) so we can plug them into the system.
[tex]\left \{ {{A(3)+B(2)=38} \atop {2A(3)-B(2)=16}} \right.[/tex]
[] Now, we can solve this with a graphing calculator. Let A be x and B be y for the sake of graphing.
A = x
B = y
[tex]\left \{ {{x(3)+y(2)=38} \atop {2x(3)-y(2)=16}} \right.[/tex]
-> See attached
[] We can see the lines intersect at (6, 10) so the answer is A = 6 and B = 10.

Ten years ago the father was six times as old as his daughter. After ten years, he will be twice as old as his father . Determine their present age ..
Let
10years ago
Daughter's age=xFather's age=6x10years after
Daughter's age=x+20Father's age=6x+20ATQ
[tex]\\ \tt\hookrightarrow 6x+20=2(x+20)[/tex]
[tex]\\ \tt\hookrightarrow 6x+20=2x+40[/tex]
[tex]\\ \tt\hookrightarrow 4x=20[/tex]
[tex]\\ \tt\hookrightarrow x=5[/tex]
Father's present age=6x+10=6(5)+10=30+10=40yrsDaughter's present age=x+10=5+10=15yrs▪︎If ten years ago , the age of daughter was x years , then , ten years ago the age of her father was 6x years ▪︎
Present age of father = ( 6x + 10 ) years Present age of the daughter = ( x + 10 ) yearsTen years after ,
Father's age = ( 6x + 10 + 10 ) years => ( 6x + 20 ) years Daughter's age = ( x + 10 + 10 ) years => ( x + 20 ) yearsAccording to the question,
▪︎6x + 20 = 2 ( x + 20 )
6x + 20 =! 2x + 40 6x - 2x = 40 - 40 4x = 20 x = 5Therefore , Present age of the Father = 6x + 10 = 6 × 5 + 10 = 40 years and present age of the daughter,
x + 10 = 5 + 10 = 15 yearshence , the age of his daughter is 15 years
