Ramon rides his bike 27 miles per hour faster than Hector rides his bike
ramon rides his bike 3 miles per hour slower than Hector rides his bike
Ramon rides his bike 27 miles per hour slower than Hector rides his bike
The third option is right. Raman rode 3miles/hr slower than Hector
Step-by-step explanation: Distance covered by Raman is 45miles In 3hours., his speed is 15miles/hr
Raman: 45=15×3 (45miles in 3hrs)

if the population of a city is 158,000 and is
decreasing by 8% every year, what will the
population be in 5 years?
Answer:
~ 104 135
Step-by-step explanation:
Decreasing by 8% each year means 92% is left each year
Formula
FV = PV ( i)^n FV = population in future PV = pop now
i = 92% in decimal form = .92 n = years = 5
FV = 158000(.92)^5 = 104135
A percentage is a way to describe a part of a whole. The population of the city after 5 years will be 104135.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the population of a city is 158,000 and is decreasing by 8% every year. Therefore, the population of the city after 5 years will be,
Population after 5 years = 158,000(1-0.08)⁵
= 158,000 × 0.659
= 104134.8807 ≈ 104135
Hence, the population of the city after 5 years will be 104135.

Answer:
O 4th option : (-4, -2)
Step-by-step explanation:
⇒ 9x - 9y = -18
⇒ -6x + 9y = 6
3x = -12x = -49(-4) - 9y = -18-36 - 9y = -18-9y = 18y = -2⇒ (x , y)
⇒ (-4, -2)
Answer:
(-4, -2)
Step-by-step explanation:
When using the elimination method, we combine the equations to get one. To combine them, we have to find a term with a number that is either positive or negative to the other, example : -6y and 6y, or 4x and -4x. We then take them and combine both equations to get one. Becuase they are the same, they simply cancel each other out.
9x - 9y = -18
-6x + 9y = 6
3x = -12
Divide both sides by 3 to get x alone
x = -4
Now, to find the y value, we can now plug in what we found for x.
9(-4) - 9y = -18
-36 - 9y = -18
Add 36
-9y = 18
Divide by -9
y = -2
Therefore making the solution, (-4, -2)

A triangle has angles measuring 35º and 65º. What is the measure of the triangle's third
Answer:
Mean=30
Median=30.5
Mode=None
Range=11
Step-by-step explanation:
The mean is all the numbers added together then divided by how many numberes there are.
24+28+33+35=120
120/4=30
Median is the the middle of the data set when arranged least to greatest. Since its a even number the median will consist of two numbers. 28 and 33
28+33=61
61/2=30.5
Mode is the number most seen in the data set. Theyre all seen once so no mode
Range is the highest value subtracted from the lowest.

The area of the figure which consist the two semicircles and one rectangle with 4×8 ft dimensions is 44.6 ft².
What is the area of a rectangle?Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,
A=a\times b
Here, (a)is the length of rectangle and (b) is the width of the rectangle
The given figure is in two parts. It is made with 2 semicircles and 1 rectangle. The length of the rectangle part is 8 ft and width of it is 4 ft long. Thus, the area of this part is,
[tex]A_r=8\times4\\A_r=32\rm\; ft^2[/tex]
There are two semicircles, which make one complete circle. Thus, the area of this two semicircle with radius 2 ft, is,
[tex]A_c=\pi \times2^2\\A_c=12.57\rm\; ft^2[/tex]
Thus, the area of this composite figure is,
[tex]A=A_r+A_c\\A=32+12.57\\A=44.57\rm\; ft^2\\A=44.6\rm\;ft^2[/tex]

If the radius of a sphere is increasing at the constant rate of 3 centimeters per second, how fast is the volume changing when the surface area is 10 square centimeters
How fast the volume of the sphere is changing when the surface area is 10 square centimeters is it is increasing at a rate of 30 cm³/s.
To solve the question, we need to know the volume of a sphere
Volume of a sphereThe volume of a sphere V = 4πr³/3 where r = radius of sphere.
How fast the volume of the sphere is changingTo find the how fast the volume of the sphere is changing, we find rate of change of volume of the sphere. Thus, we differentiate its volume with respect to time.
So, dV/dt = d(4πr³/3)/dt
= d(4πr³/3)/dr × dr/dt
= 4πr²dr/dt where
dr/dt = rate of change of radius of sphere and 4πr² = surface area of sphereGiven that
dr/dt = + 3 cm/s (positive since it is increasing) and 4πr² = surface area of sphere = 10 cm²,Substituting the values of the variables into the equation, we have
dV/dt = 4πr²dr/dt
dV/dt = 10 cm² × 3 cm/s
dV/dt = 30 cm³/s
So, how fast the volume of the sphere is changing when the surface area is 10 square centimeters is it is increasing at a rate of 30 cm³/s.

Point C has coordinates (2,0).
Find an equation of the line that passes through C and is perpendicular to AB.
equation needs to be in the form ax+by= c
a and b need to he integers ASAP PLS HELP
Answer:
x - 6y - 2 = 0
Step-by-step explanation:
Let “m” be the slope of line AB
and “a” be the slope of the line that passes through C and is perpendicular to AB
Then
[tex]m = \frac{6-0}{1-2} =-6[/tex]
The second line is perpendicular to AB
then
m × a = -1
then
-6 × a = -1
then
[tex]a=\frac{1}{6}[/tex]
C(2,0) lies on the line of equation y=ax+b
⇔ C(2,0) lies on the line of equation y=(1/6)x+b
⇔ 0 = (1/6)×2 + b
Then b= -1/3
Therefore Our equation is :
y = (1/6)x - 1/3
⇔ 6y = x - 2
⇔ x - 6y - 2 = 0
