The gravity coaster travels 340 meters in 10 seconds. The hurricane coater travels 190 meters in 5 seconds. Both coaters travels at a constant. Mario wants to ride the faster roller coaster. How fast does the gravity coaster travel? Find the unit rate.
Answers
Answer:
Mario would like to ride Hurricane coaster.
Gravity coaster travels at a unit rate of 34 m/s.
Step-by-step explanation:
Distance traveled by Gravity coaster = 340 meters
Time taken by Gravity coaster = 10 seconds
Distance traveled by Hurricane coaster = 190 meters
Time taken by Hurricane coaster = 5 seconds
Unit rate is nothing but the distance traveled by each coaster in unit time.
To find the unit rate, we can use the following formula:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Unit rate or speed of Gravity coaster = [tex]\frac{340\ m}{10\ s} = 34\ m/s[/tex]
Unit rate or speed of Hurricane coaster = [tex]\frac{190\ m}{5\ s} = 38\ m/s[/tex]
So, the faster coaster is the Hurricane coaster.
Mario would like to ride Hurricane coaster.
Gravity coaster travels at 34 m/s.

[tex]1\frac{13}{15}[/tex] is the solution for [tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex]
What is Fraction?Fractions represent the parts of a whole or collection of objects.
The given expression is
[tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex]
Firstly we need to convert this mixed fraction to improper fraction.
Improper fractions are fractions whose numerator is greater than denominator.
((15×3)+10)/15 - ((15×1)+12)/15
(45+10)/15 - (15+12)/15
55/15-27/15
15 is the LCM
(55-27)/15
28/15
Now we convert this to improper fraction
[tex]1\frac{13}{15}[/tex]
Hence [tex]1\frac{13}{15}[/tex] is the solution for [tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex].

What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Ashley recently opened a store that uses only natural ingredients. She wants to advertise her products by distributing bags of samples in her neighborhood. It takes one person \dfrac{2}{3} 3 2 start fraction, 2, divided by, 3, end fraction of a minute to prepare one bag. How many hours will it take Ashley and 4 of her friends to prepare 1575 bags of samples?
Answers
Answer:
5.3 hours
Step-by-step explanation:
Ashley recently opened a store that uses only natural ingredients. She wants to advertise her products by distributing bags of samples in her neighborhood. It takes Ashley 2/3 of a minute to prepare one bag. It takes each of her friends 75% longer to prepare a bag. How many hours will it take Ashley and 4 of her friends to prepare 1575 bags of samples?
Time it takes 1 person to preprate one bag = 2/3 min
Time it takes each friend of Ashley: 75% more than 2/3 min
75% × 2/3 minutes
=75/100 × 2/3 minutes
= 0.75 × 2/3
= 0.5 min
= 1/2 minutes
Friends = 2/3 min + 1/2 min = 7/6 min per friend
Time it takes Ashley and the 4 friends working along to prepare one bag:
Ashley's time per bag = 1 bag / (2/3) min
= 3/2 bag/min
Ashley's friends time per bag = 1 bag / (7/6) min
= 6/7 bag/min
Total = 3/2 bag/min + 4 × 6/7 bag/min
= (3/2 +24/7)
= 69/14 bag/min
Time it takes to prepare 1575 bags of samples = number of bags / number of bags per min
= 1,575 bags / (69/14) bags/min
= 319.56 min
Convert to hours:
356.56 min / 60 min per hour
= 5.3 hours

eight more than three times a number is 32
Answers
Answer:
3 times 8 = 24 + 8 = 32
Step-by-step explanation:
Answer:
The number is 8
Step-by-step explanation:
3x + 8 = 32
3x = 24
x = 8
________
A number can be denoted as x. 3 times a number is 3 of that number, and 8 more than a number is that number plus 8. This relationship can be given by:
x + x + x + 8 = 32
(x + x + x) + 8 = 32
3x + 8 = 32
3x + 8 - 8 = 32 - 8
3x = 24
3x/3 = 24/3
x = 8
1. If energy is the ability to cause change, then
what evidence is there that energy is produced in
the interaction between the wind and the blades of
the wind turbine?
Answers
Answer:
We get electricity, that's all the evidence
Step-by-step explanation:
Have a GOOD DAY
We will use the idea that "energy is the ability to cause change" to study the interaction between wind and the blades of a turbine.
This is actually really trivial, if we look at the blades and they are stopped, then we can conclude that there is no wind, thus there is no energy. (By the Newton's laws, we know that there must be a force to change the movement of something).
Now if wind comes, the wind will cause a force on the blades making them rotate.
So a form of energy comes, mechanical energy, and we can see how it produces changes.
Then by the rotation of the blades, there are dynamos that can be used to charge and store energy, this is (roughly) how a wind turbine works.

Step-by-step explanation:

∵ In the rhombus, all the sides are equal in length
∵ MNOP is a rhombus
∵ MN = NO = OP = PM
∵ MN = 9x - 77
∵ OP = 3x + 7
→ Equate them to find x
∴ 9x - 77 = 3x + 7
→ Add 77 to both sides
∴ 9x = 3x + 84
→ Subtract 3x from both sides
∴ 6x = 84
→ Divide both sides by 6
∴ x = 14
→ Substitute the value of x in the expression of OP to find its length
∵ OP = 3(14) + 7 = 42 + 7
∴ OP = 49
∵ All the sides are equal in length
∴ MP = 49

∵ The diagonals of the square bisect each other
∵ STUV is a square
∵ SU and TV are its diagonals
∴ W is the mid-point of SU and TV
∴ SW = WU
∵ SW = 2x + 13
∵ WU = 8x - 41
→ Equate them to find x
∴ 8x - 41 = 2x + 13
→ Add 41 to both sides
∴ 8x = 2x + 54
→ Subtract 2x from both sides
∴ 6x = 54
→ Divide both sides by 6
∴ x = 9
→ Substitute x in the expression of SW to find it
∵ SW = 2(9) + 13 = 18 + 13
∴ SW = 31
∵ SU = SW + WU
∵ SW = WU
∴ SU = 31 + 31 = 62
∵ Diagonals of the square are equal in length
∴ SU = VT
∴ VT = 62
Find the equation of the line that passes through the following two points: (3, -7) and (7, 2)
Answers
Answer:
[tex]y=\frac{9}{4}x-\frac{55}{4}[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx + b
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
Given points: (3, -7), (7, 2)
(3, -7) = (x1, y1)
(7, 2) = (x2, y2)
To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.
First, let's find the slope. To do this, input the given points into the slope formula:
[tex]\frac{2-(-7)}{7-3}[/tex]
Simplify:
2 - (-7) = 2 + 7 = 9
7 - 3 = 4
[tex]\frac{9}{4}[/tex]
The slope is [tex]\frac{9}{4}[/tex].
To find the y-intercept, input the slope and one of the given points(in this example I'll use point (7, 2)) into the equation and solve for b:
[tex]2=\frac{9}{4}(7)+b[/tex]
[tex]2=\frac{63}{4}+b[/tex]
[tex]-\frac{55}{4} =b[/tex]
The y-intercept is [tex]-\frac{55}{4}[/tex].
Now that we know the slope and the y-intercept, we can write the equation:
[tex]y=\frac{9}{4}x-\frac{55}{4}[/tex]

The force of gravity on the surface of jupiter is about 2.5 times as strong as that on earth. ON jupiter, the height of a ball dropped from a 100-meter tower is given by the function h(t) = -25t +100 meters at t seconds. How many seconds will it take for the ball to hit the ground?
Answers
Answer:
4 seconds
Step-by-step explanation:
Given
[tex]h(t) = -25t + 100[/tex]
Required
Determine what time it hits the ground
When the ball is on the ground, the height is at 0
i.e.
[tex]h(t) = 0[/tex]
Substitute 0 for h(t) in [tex]h(t) = -25t + 100[/tex]
[tex]0 = -25t + 100[/tex]
Collect Like Terms
[tex]25t = 100[/tex]
Solve for t
[tex]t = 100/25[/tex]
[tex]t = 4[/tex]
Hence, the ball will hit the ground in 4 seconds
