Andy is 6.25 miles north of the center of town. william is at the center of town. at noon they both start walking north.
andy walks at a constant rate of 7.5 miles in 3 hours. william walks at a constant rate of 15 miles in 4 hours.
how many hours does it take william to catch up with andy?
Answers
Answer: 5 hours
Step-by-step explanation:
[tex]speed=\frac{distance}{time}[/tex]
Andy speed = 7.5/3 = 2.5 mph
William speed = 15/4 = 3.75 mph
1. Write an equation that represents the question
let h = # of hours it takes William to catch up with andy
2.5h + 6.25 = 3.75h
2. subtract 2.5h from both sides
6.25 = 1.25h
3. Divide 1.25 from both sides
[tex]\frac{1.25h}{1.25} =\frac{6.25}{1.25}[/tex]
h = 5
Therefore, we know it will take 5 hours for William to catch up with andy.

If diagonals are drawn from point a to point c . The length of line segment eb is 65 units.
Length of line segmentSince the diagonal of parallelogram bisect one another, hence:
AE=CE
EB=DE=P+15
P-8=2P-58
P=50
Hence:
EB=P+15
EB=50+15
EB=65 units
Therefore the length of line segment eb is 65 units.

this question needs one of the basic principles of angles :
the sum of all angles around one point on one side of a line is always 180°, because that line can be seen as the diameter of a circle, and the point is the center of that circle. so, all angles in one side of the line are representing a half-circle.
this special point here is clearly T.

Step-by-step explanation:
So as we know, 30/x = 100/80
100/80 = 1.25
Now we have 30/x = 1.25
Multiply both sides of the equation by x - (30/x)x = (1.25)x
Now we have 30 = 1.25x
Divide both sides by 1.25 - 30/1.25 = 1.25x/1.25

Triangle A and Triangle B are similar triangles that have corresponding angle measures of 98 degrees and 43 degrees . What is the angle measure of the third angle in Triangle A and Triangle B?
Answers
Answer:
47 degrees
Step-by-step explanation:
Similar just means they may be different sizes but have the same angle measure. That means the angles will be identical in both triangles A and B.
All angles must add up to 180 degrees. We already have two angles, so we just need to find the last one. 90+43= 133.
180-133=47.

What is an integer?An integer is a number whose values are ranges from 0 to infinite positive and zero to infinite negative.
Given that :
2a-3b = -23
a and b are consecutive
Find:
a and b
Computation:
a = b - 1
So,
2a-3b = -23
2(b-1)-3b = -23
2b - 2 - 3b = -23
-b = -21
b = 21
So
a = b - 1
a = 21-1
a = 20
Hence the solution of the given two positive consecutive even integers will be a = 20 and b = 21

2) What is the surface area of this pyramid?
Answers
Answer:
1) First find the base, then one triangle face and multiply it by four
2) 360 units squared
Step-by-step explanation:
10*10 = 100
10*13 = 130
130*2 = 260
260 + 100 = 360
Answer:
Surface Area=360
Step-by-step explanation:
All the triangles of a square pyramid are congruent meaning you can find the area of 1 and multiply by to find the total surface area of all 4 triangles.
Area of a triangle formula= bh/2
Area of 1 triangle= 13*10/2=65
Multiply by 4 to find the total surface area of the triangles: 65*4=260
Then add the area of the square base.
Area of Square base=10*10=100
Add the total area of the triangles and square base: 260+100=360
The radius of a circle is 7 millimeters. What is the circle's circumference?
Answers
Answer:
The circumference of a circle with a radius of 7 millimeters is 44.0 (rounded to the nearest tenth).
Step-by-step explanation:
The circumference of a circle is the distance around the outside of the circle. The circumference along with the diameter and radius are the 3 major aspects of a circle.
The circumference of a circle is found using this formula:
[tex]c=2\pi *r[/tex] - or - [tex]c=\pi *d[/tex]For this problem, the radius has been given, so to solve, let's use the formula: [tex]c=2\pi *r[/tex].
It has been given that the radius is equal to 7 and the unit of measure is millimeters.
So to start, let's plug the radius in the formula.
It should look like this: [tex]C=2\pi *7[/tex]
After plugging the radius into the formula, we now have to multiply [tex]2\pi[/tex] by [tex]7[/tex]; resulting in: ≈ [tex]43.9823[/tex] (estimate)
Now rounding to the nearest tenth:
≈ [tex]44.0[/tex]

If the area of a round cricket oval is 27500 square meters, Find the distance from the centre of the ground to the boundary.
Answers
The distance from the centre of the ground to the boundary based on the area given is 93.58 meters.
How to calculate the distance?From the information given, the area of a round cricket oval is 27500 square meters. The information simply wants us to calculate the radius which will be calculated thus:
Area of a circle = πr²
πr² = 27500
(3.14) × r² = 27500
r² = 27500/3.14
r² = 8757.96
r = ✓8757.96
r = 93.58
Therefore, the distance from the centre of the ground to the boundary is 93.58 meters.
