Answer 1

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

Answers

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

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]

Please help with this!!! I’ll give Brainliest!!!

Answers

Answer: y = 70° x = 110°

Steps:
X and the angle 110° correspond to eachother so x must equal 110°

110 + 110 + y(2) = 360
220 + y(2) = 360
y(2) = 360 - 220
y(2) = 140
y = 70

Check:
70 + 70 + 110 + 110 = 360
140 + 220 = 360
360 = 360 ✅

I would appreciate brainliest if this was correct and helpful! :)

solve 35% of 84 using the mental method

Answers

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

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]

To divide fractions swap the numerator (top number) and the denominator (bottom number) of the second fraction then multiply:
