Using the relation between velocity, distance and time, it is found that the equation that describes a speed greater than Bolt's record-breaking speed in 2009 is:
[tex]v > \frac{100}{9.58}[/tex]What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:[tex]v = \frac{d}{t}[/tex]
In this problem:
He runs 100 meters, hence [tex]d = 100[/tex].He runs the 100 meters in 9.58 seconds, hence [tex]t = 9.58[/tex].Hence, his velocity is:
[tex]v = \frac{d}{t} = \frac{100}{9.58}[/tex]
A velocity greater than his velocity is:
[tex]v > \frac{100}{9.58}[/tex]

What is the equation of the line that passes through the point (3,-2) and has a
slope of -22
Answer:
y = -2x + 4
Step-by-step explanation:
slope intercept form:
y = mx + b
m = slope = -2
b = y-intercept
x = x = 3
y = y = -2
Plug in the corresponding numbers to the corresponding variables:
-2 = (-2) * (3) + b
Simplify. First, multiply:
-2 = (-6) + b
Next, isolate the b. Note the equal sign, what you do to one side, you do to the other. Add 6 to both sides of the equation:
-2 (+6) = -6 (+6) + b
b = -2 + 6
b = 4
Plug in 4 for b in the equation:
y = mx + b
y = -2x + 4

Find the equation of the line that is parallel to the line y=-3x-7 and passes through the point (1,2). Write an equation in slop intercept form
Answer:
y=-3x+5
Step-by-step explanation:
y=-3x-7
slope is -3
parallel lines have the same steepness, they have the same slope. The slopes are equal.
y-y1=m(x-x1)
y-2=-3(x-1)
y-2=-3x+3
y=-3x+3+2
y=-3x+5

Solve the following fraction problem, it is written
below also. 2/3 divided by 5/6
please
help
Answer:
[tex]\frac{4}{5\\}[/tex]
Step-by-step explanation:
So, when dividing fractions, all you have to do is flip the second fraction and multiply. Like this:
[tex]\frac{2}{3}[/tex] × [tex]\frac{6}{5}[/tex] = [tex]\frac{12}{15}[/tex]
After that, all you have to do is simplify that fraction. Like this:
[tex]\frac{12}{15}[/tex] ÷ [tex]\frac{3}{3} \\[/tex] = [tex]\frac{4}{5\\}[/tex]

Answer:
x=30
Step-by-step explanation:
Hey There!
To solve this problem we use inverse operations
so given x/-5=-6 to get rid of the -5 we multiply each side by -5
-5x-5 cancels out
-6x-5=30
we're left with 30=x
solve 35% of 84 using the mental method
Answer:
29 approximately
Step-by-step explanation:
You want to estimate 35% of 84. 35% is roughly equivalent to 1/3, so multiply 84 by 1/3 (or, equivalently, divide 84 by 3), obtaining 28. Use a calculator to find 0.35(84): 29.4. This 28 is a fairly good estimate of 35% of 84 which is 29.4.
If 50 people can fit into 6 rooms. How many people
fit into 42 rooms?
Answer:
350 people can fit into 42 rooms
Step-by-step explanation:
So we can write it as a relation fraction equation:
[tex]\frac{50}{6}=\frac{x}{42}[/tex]
Where:
x represents the people can fit in 42 rooms
[tex]x=\frac{50*42}{6}[/tex]
[tex]x=350[/tex]
Therefore, 350 people can fit into 42 rooms.

What is the value of 9over 14 divided by 3over 2
Answer:
3/7
Step-by-step explanation:
To divide fractions swap the numerator (top number) and the denominator (bottom number) of the second fraction then multiply:
[tex]\frac{9}{14}[/tex]×[tex]\frac{2}{3}[/tex]
This equals:
[tex]\frac{18}{42}[/tex]
Then you must simplify. Since 6 is a factor of both the top and bottom numbers we will divide both by 6 to get:
[tex]\frac{3}{7}[/tex]

Emiko needs to go to the dentist. It takes her 65minutes to get there by riding her bike. This is 5 minutes shorter than twice the time it would takeby bus. How long does it take Emiko to get to the dentist by bus? a.35 min b.40 min c.45 min d.50 min I will brainliest
65 min by riding her bike
x min by boarding a bus
since the time taken to get to the dentist with a bus is 5min shorter than twice the time taken with a bike, it can be written as
(2x) - 5 = 65
2x = 65 + 5
2x = 70
x = 35 min. (A)
