Konnor wants to burn 250 calories while exercising for 45 minutes at the gym. on the treadmill, he can burn 6 cal/min. on the stationary bike, he can burn 5 cal/min. if t represents the number of minutes on the treadmill and b represents the number of minutes on the stationary bike, which expression represents the number of calories that konnor can burn on the stationary bike?
Given that b is the number of calories that can be burned using the stationary bike, and the burning rate is 5 cal / min, therefore:
b = 5 t
where t is the time spent on the stationary bike
Answer:
B=5t

Write a proof to show that a rectangle has congruent diagonals. Be sure to create and name the appropriate geometric figures. This figure does not need to be submitted.
Answer:
The diagonals intersect each other
Step-by-step explanation:
One of the distinguishing features of triangles is the congruency of the diagonals. The diagonals are bisected into two. Each perpendicular bisector gives a segment of the diagonal that is equal to the other.

In order for the data in the table to represent a linear function with a rate of change of –8, what must be the value of m?
m = 2
m = 3
m = 19
m = 35
Answer:
m= 19
Step-by-step explanation:
In a linear function the rate of change of y-variable respect x-variable must be constant. In mathematical terms:
Δy/Δx = constant
Given two points of the function: (x1, y1) and (x2, y2), Δy = (y2 -y1) and Δx = (x2 -x1). So,
Δy/Δx = (11 -27)/(12-10) = -8
(m -27)/(11-10) = -8
(m -27) = -8*(11-10)
m = -8 + 27
m = 19

During a sale,Susan grody paid $155 for a clothes dryer.The price paid reflects a 75% discount off the original price. Determine what is the original price of the dryer.
The original price of the dryer would be; 38.75 dollars.
How to calculate the unit price of something?Unit means 'single entity, the fundamental constructing block. Usually, it is 1 in mathematics and science. Thus, the unit price of something is the price of 1 thing.
Given that Susan grody paid $155 for a clothes dryer.
The price paid by her reflects a 75% discount off the original price.
Required the original price of the dryer.
Thus,
100 - 75 = 25%
Therefore,
155 x 25%
155 x 0.25 = 38.75
Hence, the original price of the dryer would be; 38.75 dollars.

Twelve less than negative nine times a number is equal to 8 minus 4 times the number find the number
Final answer:
The number that satisfies the original equation is -4.
Explanation:
A student's question involves finding a number that satisfies the equation: 'Twelve less than negative nine times a number is equal to 8 minus 4 times the number'.
To solve this, we set up the equation -9x - 12 = 8 - 4x.
Solving for 'x' involves simple algebraic steps.
First, add 9x to both sides to get the variable terms on one side:
-9x - 12 + 9x = 8 - 4x + 9x-12 = 8 + 5xNext, subtract 8 from both sides to isolate the variable term:
-12 - 8 = 5x-20 = 5xFinally, divide both sides by 5 to find 'x':
-20 / 5 = 5x / 5-4 = xThe number that satisfies the original equation is -4.

Among all rectangles that have a perimeter of 156, find the dimensions of the one whose area is largest. write your answers as fractions reduced to lowest terms.
The dimensions of the one whose area is largest is 39 by 39
The formula for calculating the perimeter of a rectangle is expressed as:
P = 2(L + W)
L is the length of the rectangle
W is the width
Given that the perimeter is 156, hence;
2(L + W) = 156
2L + 2W = 156
L + W = 78
W = 78 - L
The area of the rectangle is expressed as:
A = LW
A = L(78-L)
A = 78L - L^2
To get the dimensions of the one whose area is largest, dA/dL = 0
dA/dL = 78 - 2L
0 = 78 - 2L
2L = 78
L = 78/2
L = 39
Recall that 2(L+W) = 156
2(39 + W) = 156
39 + W = 78
W = 78 - 39
W = 39
Hence the dimensions of the one whose area is largest is 39 by 39

A bathtub that holds 32 gallons of water contains 12 gallons of water. begin filling it, and after 5 minutes the tub is filled. write a standard equation
Answer:
In standard equation format, the condition can be written as [tex]V=5x+12[/tex].
Step-by-step explanation:
The capacity of the bathtub is 32 gallons.
The water already in the tub is 12 gallon.
It takes 5 minutes for the tub to be filled.
Let x be the flow rate of water through tap, in gallon per minutes.
Now, the water filled in the tank in 5 minutes will be [tex]5x[/tex] gallons.
So, in equation, the given condition can be written as,
[tex]V=5x+12\\32=5x+12[/tex]
here V represents the volume of the bathtub.
Therefore, in standard equation format, the condition can be written as [tex]V=5x+12[/tex].

The standard equation for the volume of water in the bathtub at time t is V(t) = 12 + 4t, indicating the tub starts with 12 gallons and fills at a rate of 4 gallons per minute.
Explanation:To write a standard equation for filling a bathtub, we need to find the rate at which the tub fills. Since the tub starts with 12 gallons and ends up holding 32 gallons, it needs an additional 20 gallons to be filled. If it takes 5 minutes to fill these 20 gallons, then the fill rate is 20 gallons per 5 minutes.
The equation for the volume V of water in the tub at any given time t (in minutes) is:
V(t) = 12 + r × t
where r is the rate of filling the tub. We already calculated r to be 4 gallons per minute (20 gallons/5 minutes). Therefore, the equation becomes:
V(t) = 12 + 4t
This equation represents the amount of water in the bathtub at any given time t, assuming it starts with 12 gallons and fills at a rate of 4 gallons a minute.
Claire's cousin is now 3 times as old as Claire. in 10 years, her cousin will be twice as old as claire. how old is Claire now?
Claire is currently 10 years old.
Explanation:Let's assume that Claire's age is x.
According to the given information, Claire's cousin is now 3 times as old as Claire. This can be represented as Cousin's age = 3x.
In 10 years, Cousin's age will be twice as old as Claire's age. So, we can write the equation:
(3x + 10) = 2(x + 10)
Simplifying the equation:
3x + 10 = 2x + 20
Subtracting 2x from both sides:
x + 10 = 20
Subtracting 10 from both sides:
x = 10
Therefore, Claire is currently 10 years old.

When is a protractor preferred to a ruler when finding a measurement
A protractor is preferred over a ruler when measuring angles, especially in geometric shapes or when dealing with rotational aspects. While a ruler is great for measuring lengths and distances, it can't accurately measure angles.
For example, let's say you want to measure the angle between two lines on a piece of paper. A ruler can only give you an approximation by comparing lengths, but a protractor will give you an exact measurement of the angle in degrees.
To use a protractor, align the center hole of the protractor with the vertex of the angle. Then, align one side of the angle with the zero-degree mark on the protractor. Finally, read the number where the second side of the angle intersects the protractor scale. This gives you the precise measurement of the angle.
In conclusion, when dealing with angles, a protractor is the preferred tool for accurate measurements, providing exact angles in degrees.

Juan used the expression 16 – 9 – 12 + 22 to find his profit for days 2 and 3. He rewrote the expression as 16 + (–9) + (–12) + 22. Juan can use the associative and commutative properties to rewrite the expression again. Explain why he had to use the additive inverse before he could use these properties.
Answer:
Associative property and commutative property true for addition, not true for subtraction.
Step-by-step explanation:
Associative property and commutative property true for addition.
i) a + (b + c) = (a + b) + c ---> Associative property of addition
ii) a + b = b + a --> commutative property of addition.
These properties not true for subtraction.
That's the reason Juan used additive inverse before applying these property.
Hope this will helpful.
Thank you.
