Joel biked 9 miles east and then 12 miles north. If he
biked back to his starting point using the most direct
route, how many miles would he ride all together?
Answer:
36 miles
Step-by-step explanation:
His entire journey, represented with a diagram, is in the shape of a right angle triangle.
We need to first find the hypotenuse of the triangle, then, add all the sides together:
hyp² = opp² + adj²
hyp² = 9² + 12²
hyp² = 81 + 144 = 225
Find the square root of both sides:
hyp = 15 miles
Therefore, adding the three sides together:
Total distance traveled = 9 + 12 + 15
Total distance traveled = 36 miles
He would ride 36 miles altogether.
Answer:
36

What type of number is 0.25 over -0.25 whole number, intiger rational, irrational
[tex]\frac{0.25}{-0.25}[/tex] simplified will give us -1.
It's not a whole number, because it's negative. It isn't irrational because there is a determined answer. While it is rational, it more fits into integer - which is a less broad scope than rational.
Megan has A quarters and B dimes with a total value of $1.95, where A and B are both counting numbers. How many different values of A can Megan have?
Answer: The number of quarters can be 1, 3, 5 or 7
Step-by-step explanation:
Megan has A quarters and B dimes.
The value of a quarter is $0.25 and the value of a dime is $0.10
Then we have that:
A*$0.25 + B*$0.10 = $1.95
We want to know the different possible values of A.
Now, it is usefull to see the different multilpes of 0.25 (this is the odd multyples of 0.25) we only care for the ones that have a 5 in the undredth place, becauses we only can ad multiple of $0.10, so the 5 in the undredth place needs to come from this
Then the possible values of A are the odd numbers such that A*0.25 is smaller than 1.95, let's do the math:
0.25*1 = 0.25 (here 1.95 - 0.25 = 1.70, then B = 1.70/0.10 = 17) the pair is B = 17 and A = 1
0.25*3 = 0.75 (here 1.95 - 75 = 1.20, then B = 1.20/0.10 = 12) the pair is B = 12 and A = 3.
0.25*5 = 1.25 (here 1.95 - 1.25 = 0.70, then B = 0.70/0.10 = 7) the pair is B = 7 and A = 5
0.25*7 = 1.75 (here 1.95 - 1.75 = 0.20, then b = 0.20/0.10 = 2) The pair is B = 2 and A = 7
Evaluate the variable expression for x = 5, and enter your answer in the box
below.
6.(x- 9) - 5
The value of the variable expression 6.(x- 9) - 5 when x = 5 is -29.
To evaluate the variable expression for x = 5, we simply substitute 5 for x in the expression.
6.(x- 9) - 5 = 6.(5- 9) - 5
= 6.(-4) - 5
= -24 - 5
= -29
Therefore, the value of the variable expression 6.(x- 9) - 5 when x = 5 is -29.

What is the midpoint value of a data set, where the values are arranged in ascending or descending order?
A) Mode
B) Outlier
C) Median
D) Mean
E) Center of data
Answer:
Median
Step-by-step explanation:
Remember ...
Mean = Average
Median = Middle
Mode = Most (the number that appears most)
Final answer:
The midpoint value of a data set arranged in order is the median, which is the central value dividing the dataset into two halves.
Explanation:
The midpoint value of a data set, where the values are arranged in ascending or descending order, is known as the median. The median is the value that divides the dataset in half so that there are an equal number of values above and below it. In a dataset with an odd number of data points, the median is the middle value. For an even number of data points, the median is the average of the two central values. The mode is the most frequently occurring value in a set, while an outlier is an observation that is significantly different from the rest of the data. The mean represents the average of all values in the data set.
Choosing the appropriate measure of the center of data — whether mean, median, or mode — depends on the specific characteristics of the dataset, such as the presence of outliers and the distribution shape. The median is especially useful when the dataset contains outliers that may skew the mean.

Two of the sides of a right triangle are 8 and 6 units long. How long is the third side? Find all possible answers.
Answer:
10 units.
2√7 units.
- (or 5.29 units to the nearest hundredth)
Step-by-step explanation:
If the 2 sides are legs of the triangle ( that is they are at 90 degrees to each other) the third side, by Pythagoras theorem:
= √(6^2 + 8^2)
= √100
= 10 units.
The other possibility is that 8 is the length of the hypotenuse, in which case
The third side
= √(8^2 - 6^2)
= √28
= 2√7 units.

Considering two points, x1, y1 and x2, y2, the distance between them is given by
[tex]d=\sqrt {(x2-x1)^{2}+(y2-y1)^{2}}[/tex]
Similarly, the distance between these two given points will be
[tex]d=\sqrt {(34-12)^{2}+(40-11)^{2}}\\d=36.4005494464026\approx 36.4 yd[/tex]
Therefore, the distance is 36.4 yards
Jaden collected 9 of the 12 hidden treasures in his video game. Write as a decimal.
Answer:
0.75
Step-by-step explanation:
9/12 equals 3/4 which is 0.75
Answer:
0.75
Step-by-step explanation:
First, you would need to convert it to a fraction for it says "of the", which is one of the key words to a fraction.
In fraction form it would look like this:
9/12
Now, if you remember, fractions are actually division; meaning this problem is also 9 divided by 12. So let's do that!
9 divided by 12 = 0.75.
You can also simplify the fraction; 9/12 is the same as 3/4, and you should know that 3/4 is the same as 0.75

A frog is sitting on the ground when he is scared by a big dog. His movement is modeled by
the equation h = -6t2 + 6t where h is the frog's height at any given time, t. How many
seconds until the frog is back on the ground?
2 seconds
1.5 seconds
3 seconds
1 second
0.5 seconds
Answer:
Step-by-step explanation:
Model of the frog jump is
h = -6t² + 6t
When will the frog be on the ground? The frog will be on the ground at h=0
Therefore,
0 = -6t² + 6t
Divide through by 6
0 = -t² + t
0 = t(-t + 1)
So, t = 0 OR. 0 = -t + 1
So, t = 0. OR. t = 1
So, we should note that, at t = 0, was when he wanted to lift of from the ground... So, t = 0 will be discarded
So, at t = 1 is when the frog is back to the ground.
It is like it starts from the ground at the 0 seconds and get backs to the ground at 1 seconds

If two concentric circles have radii of 4 cm and 5 cm, how much longer, in cm, is the intercepted arc in the larger circle than an intercepted arc in the smaller circle for a central angle that is π2 radians?
Answer:
[tex]\dfrac{\pi}{2} cm[/tex]
Step-by-step explanation:
Given two concentric circles where:
Radius of the Larger Circle =5Radius of the smaller circle=4Length of the intercepted arc for a central angle of [tex]\dfrac{\pi}{2} =\dfrac{\frac{\pi}{2} }{2\pi} X2\pi r=\dfrac{\pi r}{2}[/tex]
For the larger circle of radius 5cm, Length of the intercepted arc[tex]=\dfrac{5\pi}{2}[/tex]
For the smaller circle of radius 4cm, Length of the intercepted arc[tex]=\dfrac{4\pi}{2}[/tex]
Difference in Arc length
[tex]=\dfrac{5\pi}{2}-\dfrac{4\pi}{2}\\=\dfrac{\pi}{2} cm[/tex]
The difference in arc lengths between the two concentric circles for a central angle of π/2 radians is approximately 1.57 cm.
To compare the lengths of arcs intercepted by the same central angle in two concentric circles, we use the formula for arc length, which in a circle is a portion of its circumference that corresponds to the central angle. For a central angle π/2 radians, the arc length is given by (rθ), where r is the radius of the circle and θ is the central angle in radians.
For the smaller circle, the arc length is 4 cm × π/2 = 2π cm, and for the larger circle, it is 5 cm × π/2 = 2.5π cm. The difference in arc lengths is 2.5π cm - 2π cm = 0.5π cm. Using the approximate value of π as 3.14159, the difference in arc lengths is approximately 1.57 cm.
