Slower bike = X
Faster bike = X+9
They both ride for 2 hours, now you have 2x and 2(x+9)
The sum of the two cyclists is 66 miles:
2x +2(x+9) = 66
Use distributive property:
2x + 2x+18 = 66
Simplify:
4x +18 = 66
Subtract 18 from both sides:
4x = 48
Divide both sides by 4:
x = 48/4
x = 12
The slower bike was going 12 mi/h
The faster bike was 12+9 = 21 mi/h.

The isosceles triangle has two sides of equal length , a , that are longer than the length of the base , b. The perimeter of the triangle is 15.7 centimeters. The equation 2a+b=15.7 models this information.
If one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base ?
Answer:
Step-by-step explanation:
Since the length of one of the longer sides, a, has been given to be 6.3, plug it into the equation.
2(6.3) + b = 15.7
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1
Answer:
Equation that can be used to find length of the base is b + 12.6 = 15.7 and the length of the base we get from this equation is 3.1 cm
Step-by-step explanation:
Given:
Length of the equal side of the Isosceles Triangle = a
Length of the base of the triangle = b
Equal sides are longer than base of the triangle.
Perimeter of the triangle = 15.7 cm
Equation representing given information = 2a + b = 15.7
To find: Equation that represent or can be used to find length of the base if longer side = 6.3 cm
Given Equation is the Equation representing the perimeter of the isosceles triangle.
Longer side = 6.3 cm = Length of the Equal Sides of the triangle.
So, a = 6.3 cm
Now,
2 × 6.3 + b = 15.7
b + 12.6 = 15.7
b = 15.7 - 12.6
b = 3.1 cm
Therefore, Equation that can be used to find length of the base is b + 12.6 = 15.7 and the length of the base we get from this equation is 3.1 cm
Given that the circles are congruent, can you conclude that YZ=BC?
Answer options: yes, no
Answer:
Answer is yes
Step-by-step explanation:
Given in the picture are two circles which are congruent.
This suggests that the radii of the two circles are equal.
Also the central angle of the two circles are congruent (given)
Consider triangles ABC and XYZ,
AC =XY: AB = YZ:
Angle A = Angle X
By SAS theorem, the two triangles are congruent.
Hence BC = YZ
So yes is answer.
There are 5 red pens,3 blue pens and 2 green pens in a box. Gary takes at random a pen from the box and gives the pen to his friend. Gary then takes at random another pen from the box . work out the probability that both pens are the same colour.
please help
➷ Find the total number of pens:
5 + 3 + 2 = 10
The probability of taking a red the first time is 5/10
The probability of taking a blue the first time is 3/10
The probability of taking a green the first time is 2/10
If you want to take the same colored pen again, there would be 1 less of the total pen (as it hasn't been replaced) and there would be one less of that color (as one has already been taken)
Therefore:
The probability of taking a red again is 4/9
The probability of taking a blue again is 2/9
The probability of taking a green again is 1/9
Multiply the values for the same color together:
5/10 x 4/9 = 20/90
3/10 x 2/9 = 6/90
2/10 x 1/9 = 2/90
Add these values together:
20/90 + 6/90 + 2/90 = 28/90
Your answer is 28/90

what is 1/100,000,000 as a power of 10
A power of 10 is the number 10 multiplied by itself by the number of times indicated by the exponent. Thus, shown in long form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000.
1/100,000,000 expressed as a power of 10 is 10-8, reflecting the movement of the decimal point 8 times to the left.
The question asks for the expression of 1/100,000,000 as a power of 10. To find the answer, we need to realize that this fraction is the same as moving the decimal point 8 places to the left from 1, making it 0.00000001. This operation is equivalent to the negative power of 10, because you're making the number smaller (or dividing). Remembering that the exponent represents how many times we move the decimal place, we can express 1/100,000,000 as 10-8.

ben wants to bike 12 miles. so far he has biked 2/3 of those 12 miles. How many miles has Ben biked
Answer:
Ben had biked 8 miles
Step-by-step explanation:
You would need to take 12 and divide it by three . That would make 4. After that you would take 4 and multiply it by 2 since he rode 2/3 miles of 12. Then you would end up with 8.
Final answer:
Ben has biked 8 miles of the 12 miles he wants to, as he has completed 2/3 of his intended distance.
Explanation:
To calculate the number of miles Ben has biked, we simply need to multiply the total distance he wants to bike by the fraction of the trip he has completed. Ben wants to bike 12 miles, and he has biked 2/3 of that distance. Multiplying these together gives us 2/3 * 12 = 8 miles. Therefore, Ben has biked 8 miles so far.

Both rectangles have the same dimensions and shape. P'Q'R'S' is a translated image of PQRS, shifted 3 units right and 3 units up. They are congruent but not identical due to their position.
Step-by-step comparison of rectangles PQRS and P'Q'R'S':
1. Original coordinates:
Assume specific coordinates for the vertices of rectangle PQRS. For example, let P = (1, 2), Q = (5, 2), R = (5, 6), and S = (1, 6).
2. Translation:
A translation moves every point in the shape the same distance and in the same direction. Since Rashid translated rectangle 3 units up and 3 units to the right, add 3 to x-coordinate and 3 to y-coordinate of each point in PQRS to find corresponding points in P'Q'R'S'.
3. New coordinates:
P' = (1 + 3, 2 + 3) = (4, 5)
Q' = (5 + 3, 2 + 3) = (8, 5)
R' = (5 + 3, 6 + 3) = (8, 9)
S' = (1 + 3, 6 + 3) = (4, 9)
4. Comparison:
Shape:
Both rectangles PQRS and P'Q'R'S' are rectangles because a translation preserves the shape of the original figure.
Size:
They have the same dimensions (length and width) as the translation only shifts the position without altering the size.
Orientation:
They maintain the same orientation relative to the axes, meaning their sides remain parallel and perpendicular to the x and y axes.
Position:
The key difference lies in their position. P'Q'R'S' is located 3 units to the right and 3 units above PQRS.
5. Rectangles PQRS and P'Q'R'S' are congruent (same size and shape) but not identical (different positions).
P'Q'R'S' is a translated image of PQRS, moved 3 units to the right and 3 units up.
Examine the diagram at right. The smaller triangle (inside of the larger triangle) is similar to larger triangle. How can you solve for x? Now , determine the lengths of m and p . Note that when no units are given on measurements , you may assume that all units are the same .
As the exercise says, the triangles are similar. So, we can set up proportions between correspondent sides.
In order to solve for x we can set up the proportion between the horizontal and vertical sides:
[tex]28\div 11.2 = 27+x \div x[/tex]
Solving this proportion for x implies [tex]x=18[/tex]
Now you can solve for m and p using the pythagorean theorem, because both triangles are right:
[tex]m = \sqrt{18^2+11.2^2} =21.2[/tex]
Then, we know that the hypothenuse of the big triangle is m+p, so we have
[tex]m+p=\sqrt{(18+27)^2+28^2} = 53[/tex]
which implies
[tex]p = 53-p = 53-21.2=31.8[/tex]
The ratio of the given to similar triangles is 0.4. value of the x, m, and p is 18, 21.2, and 31.8.
What are similar triangles?Similar triangles are triangles whose corresponding sides are in ratio, while the corresponding angles are of equal measure.
What is the ratio of the given triangles?As the two sides of the triangles are already given, therefore, the ratio of these two triangles are,
[tex]\dfrac{11.2}{28} = \dfrac{2}{5}[/tex]
What is the value of x?As we already know the ratio of the two triangles, therefore,
[tex]\dfrac{x}{27+x} = \dfrac{2}{5}\\\\5x = 54 + 2x\\\\5x-2x = 54\\\\3x = 54\\\\x = 18[/tex]
Hence, the value of x is 18.
What is the value of m and p?As the given triangle is a right-angled triangle, therefore, we can use the Pythagorean theorem to find the value of m,
[tex](Hypotenuse)^2 = (Perpendicular)^2+(Base)^2\\\\m^2 = x^2 + (11.2)^2\\\\m^2 = 18^2 + 11.2^2\\\\m^2 = 324+125.44\\\\m^2 = 449.44\\\\m = 21.2[/tex]
Thus, the value of side m is 21.2 units.
The value of m and p can be found using the same ratio, we already have for similar triangles,
[tex]\dfrac{m}{m+p} = \dfrac{2}{5}\\\\\dfrac{21.2}{21.2+p} = \dfrac{2}{5}\\\\106= 42.4 + 2p\\\\p = 31.8[/tex]
Thus, the value of the x, m, and p is 18, 21.2, and 31.8.
