Parker drove 8 miles in 15 minutes. If he drove at a constant rate, how far did he travel in one hour?
Weird question but, whenever you divide by 1/4 or multiply by 4/1, will you always get the same answer.
(25 points if you answer this.)
Answer:
yep
Step-by-step explanation:
when you divide a fraction u can use the KCF method which is basically:
(keep) the first fraction the same
(change) the division sign in the middle to a multiplication sign
(flip) the second fraction
basically because you have to flip the 1/4 when you divide it, it'll be the same as a 4/1 anyways

mrs.gretta is teaching a 5th grade class. She is standing 12 meters in front of ethan. isabella is sitting to ethans right. if isabella and mrs.gretta are 15 meter apart how far apart are ethan and isabella?
Answer:
Ethan and Isabella are 9 meters apart.
Step-by-step explanation:
1. We can solve this using the Pythagorean Theorem, a²+b²=c².
2. Mrs. Gretta is standing 12 meters in front of Ethan, so a=12.
3. Isabella is sitting to Ethan's right, but we don't know how far away, so b=x.
4. Mrs. Gretta is 15 meters from Isabella, so c=15.
5. Plugging these variables into the equation, we get 12²+x²=15² which equals 144+x²=225.
6. We can move 144 to the other side to get x²=81, then square the 81 to get x=9.
7. Therefore, the answer is 9. Ethan and Isabella are 9 meters apart.

a wildlife photographer photographs a crocodile and then paddles against a river current for 6 km. Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake. She paddles across the lake for one hour longer than she paddled up the river. find the speed of the boat as she paddles the lake if the river current is 2 km/h
Answer:
6 km/hr or 5 km/hr
Step-by-step explanation:
In the lake, she goes 15 km at x km/hr (named)
In the river, she goes 6 km at x-2 km/hr (current=2 km/hr)
So, the time in the lake - the time in the river = 1 hour (given)
15/x - 6/x-2 = 1 --> x=6;x=5
The speed of the boat as the photographer paddles the lake if the river current is 2 km/h is 6 km/hr and this can be determined by forming the quadratic equation.
Given :
A wildlife photographer photographs a crocodile and then paddles against a river current for 6 km.Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake.She paddles across the lake for one hour longer than she paddled up the river.According to the given data, if the river current velocity is 2 km/hr then let the speed in the lake be x km/hr. So, the speed of the photographer in the river is (x - 2) km/hr
Therefore, the speed of the boat as she paddles the lake if the river current is 2 km/h is given by:
[tex]\dfrac{15}{x} - \dfrac{6}{x-2}=1[/tex]
Now, simplify the above expression.
[tex]15(x-2)-6(x)=x(x-2)[/tex]
[tex]15x-30-6x=x^2-2x[/tex]
[tex]x^2-11x+30=0[/tex]
Factorize the above equation.

x(x - 6) - 5(x - 6) = 0

Two vertical posts stand side by side. One post is 8 feet tall while the other is 17 feet tall. If a 24 foot wire is stretched between the tops of the posts, how far apart are the posts?
Answer:
22 1/4 feet
Step-by-step explanation:
you can sketch this problem to be a right triangle with a hypotenuse of 24 feet and one leg of 9 feet (17 - 8).
use Pythagorean Theorem to find the base side, which represents the distance between the posts
a² + 9² = 24²
a² + 81 = 576
a² = 576 - 81
a² = 495
a = [tex]\sqrt{495}[/tex]
a = [tex]\sqrt{9}[/tex] · [tex]\sqrt{55}[/tex] = 3[tex]\sqrt{55}[/tex], which is approx 22.25
Answer:
about 22.25 feet
Step-by-step explanation:
You can think of it like a triangle, which you can see at the bottom
Then, use the pythagorean theorem, [tex]a^2 + b^2 = c^2[/tex].
you have a = 9 and c = 24, so
[tex]9^2 + b^2 = 24^2\\81 + b^2 = 576\\b^2 = 495\\b = \sqrt{495} = 3\sqrt{55} = about 22.25[/tex]

The total cost of a compact disc, including a 6% sales tax, is $14.31.
What is the price before the tax?
$13.50
$13.45
$13.44
$15.17
The cost of a compact disc before the sale tax is $13.45. The correct option is B.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the total cost of a compact disc, including a 6% sales tax, is $14.31.
The cost before the sale tax will be calculated as,
Cost = 14.31 x ( 1 - 0.06 )
Cost = 14.31 x 0.94
Cost = $13.45
