The speed of one car is 20% less than the speed of a second car. What per cent more time does the first car need to travel the same route as the second car?
Answer:
25% or more
Step-by-step explanation:
t1 = d1/v1 , t2 = d2/v2.
d1 = d2 , and v1 = 0.8 v2
t1 / t2 = d1/d2 x v2/v1 = v2/v1 ( as d1 = d2 )
t1/t2 = v2 / v1 = v2/0.8 v2 = 1/0.8 = 1.25

Answer:
last option; h = 2t - d
Step-by-step explanation:
t = 1/2(d + h)
t = [tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex]
now multiply each side by 2 to eliminate denominator
2t = 2 ([tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex])
2t = d + h
h = 2t - d
write the equation for the line in slope-intercept form (2,-3) (-1/2) ( HELP PLEASE )
Answer:
A linear equation is a fancy term for a straight line, which can be created by joining 2 points.
A point can be defined by (x, y), where x and y are the horizontal distance and the vertical distance respectively from point (0,0) (called the origin).
There are 3 ways to define a line:
(1) The slope-intercept form
y = mx + b, in which m is the slope, b is the y-intercept, where the line crosses the vertical axis at (0, b). If values of m and b are given, you can substitute and write the equation right away.
The slope, m, is calculated by rise (vertical difference between 2 points on the line) divided by run (horizontal difference between the 2 points on the line)
Step-by-step explanation:
or example, if 2 points on the line are
(x1, y1) and (x2, y2)
Then slope = (y1– y2)/(x1 — x2)
If m > 0, then the line rises to the right.
If m = 0, then the line is horizontal.
If m < 0, then the line rises to the left.
If the line is in the form x = c, where c is a constant, then the line is vertical.
(2) Point slope form
m = (y — y1)/(x — x1), when (x1, y1) and m are given.
In other words,
m(x — x1) = y — y1
mx — m(x1) = y — y1
y = mx — m(x1) + (y1)
Note that b = -m(x1) + (y1)
(3) linear form
ax + by + c = 0, where a, b, and c are constants.

Answer:
y = 30200
x = -29950
Step-by-step explanation:
1.)
Let x represent children and y for adults.
200x + 450y = 7,600,000
x + y = 250
2.)
200x + 450y = 7,600,000
x + y = 250
-200(x + y = 250)
-200x + -200 = -50000
200x + 450y = 7,600,000
+ -200x + -200 = -50000
——————————————-
250y = 7550000
y = 30200
x + 30200 = 250
x = -29950
Uhm so I don’t know why for children I got a negative number? The wording for this question is very weird.
A 22 km walk is completed in 5 hours and 30 min.
What is the average speed?
Answer:
121 km\hr
Step-by-step explanation:
displacement=speed÷time
then. speed = displacement×time
= 22 × 5.5
= 121 km\hr

3/4 divided by 1/2 brainleist if answer
Answer:
1 2/4 (1 1/2)
Step-by-step explanation:
keep, change, flip is how you solve these kinds of problems
the 3/4 stays the same
you turn the ÷ into x
and flip the 1/2 (2/1)
so it becomes
3/4x2/1= 1 2/4 (simplified is 1 1/2)

Answer:
a=66m b=4.58cm
Step-by-step explanation:
a=5610 divided by 85=66 so 66m ×85 m =5610 meters squared
b=330cm ÷ 72 cm is 4.58. So 72×4.58=329.76 so rounded =330
What’s the slope of C=50t+100
Answer:
