A biker cycles 9 miles in 2/3 of an hour. Make a chart and fill it in to show how far he will bike if he maintains the same pace for 2 hours 3 hours and 3.5 hours
Answer:
27 miles, 40.5 miles, and 47.25 miles
Step-by-step explanation:
9 miles in 2/3 hours. To get to a whole number, we can multiply by the reciprocal of 2/3, which is 3/2. 2/3*3/2=1. Now lets multiply 9 by 3/2. 9*3/2=13.5
We now have a unit rate which is 13.5 miles each hour.
Now lets solve for 2 hours.
13.5*2= 27 miles
Now lets solve for 3 hours.
13.5*3=40.5 miles
Now lets solve for 3.5
13.5*3.5= 47.25 miles
Simon drives 75 km at an average speed of 120 km/h and then 9 km at 70 km/h without stopping. What is the average speed for the whole journey to 1 dp?
95km/h is the average speed for the whole journey
What is Speed?Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement
Given,
Simon drives 75 km at an average speed of 120 km/h
9 km at 70 km/h without stopping.
We need to find the average speed.
Average speed = Total distance/Total time
The total distance is 75km+9km
84 km
The average speed is sum of speeds by two
120+70=190/2=95km/h
Hence, 95km/h is the average speed for the whole journey

Mike and Tom are trying to make weight for wrestling. Mike weighs 200 lbs and is
losing 2 Lbs a week. Tom weighs 160 lbs and is gaining 3 pounds a week. How many
weeks will both boys weigh the same?
Answer:
8 weeksStep-by-step explanation:
Let the number of weeks be x after which both boys have same weight.
Mike's weight after x weeks:
200 - 2xTom's weight after x weeks:
160 + 3xEquate both expressions and solve for x:
200 - 2x = 160 + 3x3x + 2x = 200 - 1605x = 40x = 8Answer:
After 8 weeks, both boys weigh same.
Step-by-step explanation:
Forming the equation,
→ 200 - 2x = 160 + 3x
Now the value of x will be,
→ 200 - 2x = 160 + 3x
→ -2x - 3x = 160 - 200
→ -5x = -40
→ x = -40/-5
→ x = 40/5
→ [ x = 8 weeks ]
Hence, the value of x is 8.

Khadija is blocking off several rooms in a hotel for guests coming to her wedding. The hotel can reserve small rooms that can hold 3 people, and large rooms that can hold 4 people. Khadija reserved 2 more small rooms than large rooms, which altogether can accommodate 48 guests. Graphically solve a system of equations in order to determine the number of small rooms reserved, x, and the number of large rooms reserved, y.
There are 8 small rooms and 6 large rooms.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Let s be the number of small rooms reserved.
Let l be the number of large rooms reserved.
Each small room can accommodate 3 guests, hence s small rooms can hold 3s guests.
Each large room can accommodate 4 guests, so all large rooms can hold 5l guests.
Thus, the total number of guests
48 =3s+4l
3s+4l=48
3s+4l=48

Using the Work time problem solving technic, Betty and Bullwinkle to mow the entire lawn in 30 minutes if they are working together.
As we know that if A is complete the work of z in x days and B is complete the same work (z) in y days then both of can do complete work together then Equation of both A and B are completing work (z) together in
( 1/x + 1/y = 1/z ) days
Since Betty can mow a lawn is 120 minutes, then
Betty's mowing rate is 1/120th of a lanw per minute.
Since Bullwinkle can mow a lawn is 40 minutes, then Bullwinkle mowing rate is 1/40th of a lawn per minute.
Suppose working together they can a lawn in x minutes.
both together they can mow a lawn is x minutes, then their combined mowing rate is 1/x th of a lawn per minute.
To get the equation,
the sum of their mowing rates must equal their combined mowing rate,
1/40 + 1/120 = 1/x
Solve that by multiplying through by LCD of 40 and 120 is 120 then 4x = 120 => x = 30

The values of m<4 and m<6 are 160° and 20° respectively
How to find the value of m<4 and m<6?
To solve this problem, we need some angle geometry knowledge:
Given that: m<6 = 1/8 m<4
Since m<6 = 1/8 m<4. Thus, m<4 = 8.m<6
m<6+ m<4 = m<6 + 8.m<6 = 9.m<6 (Algebra)
m<6+ 8.m<__ = 180° will be:
m<6+ 8.m<6 = 180°
Note: m<6 + m<5 = 180° (angles on a straight line) and m<5 = m<6 (alternate angles)
m<6+ 8.m<6 = 180°
9.m<6 = 180°
m<6 = 180/9 = 20°
m<4 = 8 x m<6
m<4 = 8 x 20° = 160°
Therefore, the values of m<4 = 160° and m<6 = 20°

does the graph of a power function and the graph of its inverse demonstrate
symmetry? Explain your reasoning.
Yes, the graphs of a power function and its inverse are symmetric about the line y=x.
What is an inverse function?
A function that "undoes" another function is called an inverse. In other words, if f(x) yields y, then y entered into the inverse of f yields the output x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f⁻¹.
What is a power function?
Any function where y = xⁿ, where n is any real constant integer, is referred to be a power function. In reality, many of our parent functions, including linear and quadratic functions, are power functions.
Here,
The graphs of self-inverse functions are symmetrical about the line y=x. The domain of a one-to-one function f is the same as the range of its inverse f⁻¹ and the range of f is the same as the domain of f⁻¹.
Hence, the graphs of a power function and its inverse are symmetric about the line y=x.

For example, 6 is multiplied by itself four times, yielding 6 6 6 6. This is written as [tex]6^{4}[/tex]. The exponent is 4 and the base is 6.
Given that 1000 to the power of m divided by 100 to the power of n
When powers of the equal base are divided, the same base is placed and the exponents are subtracted, which is an important mathematical property of powers.
Then, as powers of the same base, we can write 1000m and 100n:
1000m = [tex](10^{3})^{m}[/tex] = [tex]10^{3m}[/tex]

Given that,
Bernie has decided to purchase a new car of $ 18,575.
The sales tax is 7.40%
Now,
18,575 x 7.40% = 1,374.55
Now, summing up the result of sales tax and purchase price, we get,
18,575 + 1,374.55 = 19,949.55
Bernie will give registration fees of $795
and, a documentation fees: $110
Now , we will sum up all the above information, i.e.,
= 19,949.55 + 795 + 110
= 20,854.55
Now, divide the result of documentation fees and registration fees by 5

The smallest possible perimeter of the triangle is, 72.4 inches.
What is perimeter?
The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimeters, meters, inches, and feet.
As given the longest side of an acute triangle measure 30 inches.
The two remaining sides' combined length must be longer than the opposite side.
The sum of the two remaining sides should be greater than 30 inches if the side is 30.
Assume the other two sides add up to 31 inches.
So, The perimeter of a triangle is equal to the sum of its three sides, which comes to 30 + 31 = 64 inches.
