Step-by-step explanation:
Usain Bolt ran a 5-k (5 kilometer) race in 7.5 minutes. You observe a rabbit run across your yard (a distance of 30 meters) in 2.4 seconds.
Who is faster, Usain Bolt or the rabbit? PLEASEE HELPP PLEASE YHIS IS DUE IN 10 MIN RN I WILL GOVE BRAINLIEST WITH EXPLANATION THANK YOU!
Answer:
Usain Bolt
Step-by-step explanation:
1 kilometer = 1,000So, 5 kilometers = 5,000 metersFind out their time per 1 meter:
Usain Bolt:
Set up a proportion: [tex]\frac{5000}{7.5} = \frac{1}{x}[/tex] Cross multiply, then divide: 1 × 7.5 = 7.5, 7.5 ÷ 5000 = 0.0015The rabbit:
Set up a proportion: [tex]\frac{30}{2.4} = \frac{1}{x}[/tex] Cross multiply, then divide: 1 × 2.4 = 2.4, 2.4 ÷ 30 = 0.08Compare the times:
Usain Bolt: 0.0015 minutes in 1 meterRabbit: 0.08 seconds in 1 meterBecause 0.0015 minutes is faster than 0.08 seconds, Usain Bolt is the answer.I hope this helps!

Mid-ocean ridge rift zones produce new crust. Depending on the rift, 1 cm/yr to more than 10 cm/yr can be produced.
1. The distance between Newfoundland, Canada, and Ireland is roughly 3,320 kilometers. If the Mid-Atlantic Ridge is spreading at 4 cm/year (0.00004 km/year) in that area, how long ago did the Atlantic Ocean separate Canada from Ireland?
Answer:
1cm/year
Step-by-step explanation:
If the Mid-Atlantic Ridge is spreading 4cm/year, then it took 83000000 years for the Atlantic Ocean to separate Canada from Ireland.
What is the conversion of units?The conversion of units by using dimensional analysis is the changing of the unit of a particular parameter from one form to another.
This technique takes a logical approach when solving and converting from one unit to another.
From the given information:
A rift can be produced between 1cm/yr to more than 10 cm/yr
The separation between Canada and Ireland is roughly 3320 kilometers.
Then, the number of years it took the Atlantic Ocean to separate Canada from Ireland is:
[tex]\mathbf{= \dfrac{3320 \ km }{ 0.00004 \ km/year }}[/tex]
= 83000000 years

Given Area of ΔDCF = 63 cm²To findArea of ΔABCSolutionLet the area of ABC be A, thenA = 1/2bh, where b= AC is the base and h is the height of the triangle----------
The triangle DCF can be divided into DEC and DEF as per picture and the area of them is:
Area of ΔDEF
1/2DE*h2Area of ΔDEC
1/2DE*h1Since D and E are midpoints of AB and BC:
DE = 1/2AC = 1/2bAnd h1 = 1/2h, h2 = 1/2h1 = 1/2*1/2h = 1/4hSo the area of ΔDCF is:
1/2(1/2bh1) + 1/2(1/2bh2) =1/2(1/2b*1/2h) + 1/2(1/2b*1/4h) = 1/8bh + 1/16bh =3/16bhSince the area of ABC is A = 1/2bh we have:
3/8*1/2bh = 3/8A and 3/8A = 63Solving for A:
A = 63*8/3 = 168 cm²Find the measures of two supplementary angles,

Nina has x coins. Clayton has 5 fewer coins than six times the number of coins Nina has. Write an expression for the total number of coins Nina and Clayton have altogether. Then simplify the expression.
Answer:
7x - 5
Step-by-step explanation:
Let
Nina = x coins
Clayton = 6x - 5 coins
Expression for the total number of coins Nina and Clayton have altogether.
Nina + Clayton
= x + (6x - 5)
= x + 6x - 5
= 7x - 5
The correct answer and expression is 7x - 5
Answer:
7x - 5

Solve for the value of x in this equation: -10x+17x-2 = 5(x+4)
I need help ASAP
Needs to be step by step
Answer:
[tex] \huge{ \bold{ \boxed{ \tt{x = 11}}}}[/tex]
Step-by-step explanation:
[tex] \text{ - 10x + 17x - 2 = 5(x + 4)}[/tex]
Subtract 10x from 17x
10x and 17x are like terms. So, the coefficients of like terms can be added or subtracted.
[tex] \dashrightarrow{ \sf{ 7x - 2 = 5(x + 4)}}[/tex]
Distribute 5 through the parentheses
[tex] \dashrightarrow{ \sf{7x - 2 = 5 \times x + 5 \times 4}}[/tex]
[tex] \dashrightarrow{ \sf{7x - 2 = 5x + 20}}[/tex]
Move 5x to left hand side ( L.H.S ) and change it's sign
Similarly , move 2 to right hand side ( R.H.S ) and change it's sign
[tex] \dashrightarrow{ \sf{7x - 5x = 20 + 2}}[/tex]
Subtract 5x from 7x
[tex] \dashrightarrow{ \sf{2x = 20 + 2}}[/tex]
Add the numbers : 20 and 2
[tex] \dashrightarrow{ \sf{2x = 22}}[/tex]
Divide both sides by 2
[tex] \dashrightarrow{ \sf{ \frac{2x}{2} = \frac{22}{2}}} [/tex]
[tex] \dashrightarrow{ \boxed{ \sf{x = 11}}}[/tex]
--------------------------------------------------------------
Now, let's check whether the value of x is 11 or not.
Verification :L.H.S = n[tex] \sf{ - 10x + 17x - 2}[/tex]
Plug the value of x and simplify
[tex] \longrightarrow{ \sf{ - 10 \times 11 + 17 \times 11 - 2}}[/tex]
[tex] \longrightarrow{ \sf{ - 110 + 187 - 2}}[/tex]
[tex] \longrightarrow{ \sf{77 - 2}}[/tex]
[tex] \dashrightarrow{ \sf{75}}[/tex]
R.H.S = [tex] \sf{5(x + 4)}[/tex]
plug the value of x and simplify
[tex] \longrightarrow{ \sf{5(11 + 4)}}[/tex]
[tex] \longrightarrow{ \sf{5 \times \: 15}}[/tex]
[tex] \longrightarrow{ \sf{75}}[/tex]
L.H.S = R.H.S
The value of x is 11 .
--------------------------------------------------------------
Rules for solving an equation :If an equation contains fractions , multiply each term by the LCM of denominators.Remove the brackets , if any.Collect the terms with the variable to the left hand side and constant terms to the right side by changing their signs ' + ' into ' - ' and ' - ' into ' + 'Simplify and get the single term on each side.Divide each side by the coefficient of variable and then get the value of variable.Hope I helped!

What is the slope of the line that passes through the points (3, 2) and (-1,2)?
Write your answer in simplest form.
Answer:
The slope is 0.
Step-by-step explanation:
slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
Given points: (-1, 2), (3, 2)
(-1, 2) = (x1, y1)
(3, 2) = (x2, y2)
To find the slope, input the given points into the formula used to find slope:
[tex]\frac{2-2}{3-(-1)}[/tex]
Simplify:
2 - 2 = 0
3 - (-1) = 3 + 1 = 4
[tex]\frac{0}{4} = 0[/tex]
The slope is 0.
Hope this helps :)

What is the value of y?
Answer:
D. 54°
Step-by-step explanation:
The sum of angles for a triangle is 180°, so we can subtract the known angle, 72 from 180.
Our answer is 108. We know that the two remaining angles are the same, so divide 108 by 2, and get 54°.
