Therefore, the lawnmower can cut grass for 2.5 hours on 5/6 of a gallon of fuel in the gas can
To find out how long the lawnmower can cut grass with 5/6 of a gallon of gas, we first need to figure out how many gallons of gas the lawnmower will use per hour:
1 hour of grass cutting = 1/3 gallon of gas
1 gallon of gas = 3 hours of grass cutting
So the lawnmower uses 1/3 gallon of gas per hour, which means that 1 gallon of gas will last for 3 hours of grass cutting.
Now we can use this conversion factor to figure out how long 5/6 of a gallon of gas will last:
5/6 gallon of gas * 3 hours of grass cutting per 1 gallon of gas = 15/18 hours of grass cutting
Simplifying this fraction by dividing the numerator and denominator by 3:
15/18=3/6
So 5/6 of a gallon of gas will last for 5/6 of 3 hours, which is equal to 2.5 hours of grass cutting.
As a result, 5/6 of a gallon of gas will last for 5/6 of 3 hours, or 2.5 hours of mowing the lawn.

For what value of c is the number "a" a solution of the equation? (If there is no solution, enter NO SOLUTION. If there are infinitely many solutions, enter INFINITELY MANY.)
4x + 1 + 7c = 8c - 3x + 6; a = -5
c = ________
Answer:
To find the value of "c" for which the number "a" (-5 in this case) is a solution of the equation, we can substitute "a" into the equation and solve for "c".
Given equation: 4x + 1 + 7c = 8c - 3x + 6
Substituting x with "a": 4(-5) + 1 + 7c = 8c - 3(-5) + 6
Simplifying the equation: -20 + 1 + 7c = 8c + 15 + 6
Combining like terms: -19 + 7c = 8c + 21
Moving all "c" terms to one side: 7c - 8c = 21 + 19
Simplifying: -c = 40
Dividing both sides by -1 to isolate "c": -c/-1 = 40/-1
Flipping the sign when dividing by a negative number: c = -40
So, the value of "c" for which the number "a" (-5) is a solution of the equation is c = -40.
Answer:
[tex]c=-40[/tex]
Step-by-step explanation:
Since a is a Solution to the Equation , then it satisfies the Equation
Substitute by [tex]x=a=-5[/tex] into the Equation [tex]4x+1+7c=8c-3x+6[/tex]
Then [tex]4(-5)+1+7c=8c-3(-5)+6[/tex]
Then [tex]-20+1+7c=8c+15+6[/tex]
By adding like-terms
Then [tex]-19+7c=8c+21[/tex]
Then [tex]8c-7c=-19-21[/tex]

Calculate the ratio
Where the conditions above are given with regard to the above triangle, the ratio AD:DB is 1:1.
What is the explanation for the above response?Since D is the midpoint of AB, we have:
AD = DB
Let M and N be the midpoints of OA and OB, respectively. Then we have:
AM = MO = x/2
BN = NO = y/2
Also, from the given information, we have:
OD = 3/7x + 4/7y
Since D is the midpoint of AB, we have:
AD + DB = AB
Substituting AD = DB, we get:
2AD = AB
Therefore:
AD = AB/2
We can express AB in terms of x and y using the law of cosines:
AB^2 = OA^2 + OB^2 - 2(OA)(OB)cos(BOA)
Since M and N are midpoints, we have:
OM = OA/2 and ON = OB/2
Therefore, using the law of cosines, we have:
MN^2 = OM^2 + ON^2 - 2(OM)(ON)cos(MON)
Substituting OM = OA/2 and ON = OB/2, we get:
MN^2 = OA^2/4 + OB^2/4 - (OA)(OB)/2 cos(BOA)
But MN = OD, so we can also express this as:
OD^2 = (3/7x + 4/7y)^2 = OA^2/4 + OB^2/4 - (OA)(OB)/2 cos(BOA)
Substituting OD^2 = (3/7x + 4/7y)^2 and simplifying, we get:
9x^2 + 16y^2 = 49(OA^2 + OB^2) - 42(OA)(OB) cos(BOA)
Substituting AB^2 = OA^2 + OB^2 - 2(OA)(OB) cos(BOA) and simplifying, we get:
9x^2 + 16y^2 = 49AB^2
Substituting AD = AB/2, we get:
9x^2 + 16y^2 = 49(2AD)^2
Simplifying, we get:
x^2 + 4y^2 = 28AD^2
We want to find the ratio AD:DB, which is the same as the ratio AD:(AB - AD). Substituting AB = 2AD, we get:
AD:(AB - AD) = AD:AD = 1:1
Therefore, the ratio AD:DB is 1:1.

Therefore, you are three times more likely to be on time than be late if you take Route C to school.
What is relative frequency?Relative frequency is a statistical term that refers to the proportion or percentage of times an event or a particular value occurs within a larger set of data. It is calculated by dividing the number of times the event or value occurs by the total number of observations in the data set.
Here,
To determine how many times more likely you are to be on time than late if you take Route C, we need to compare the heights of the green and red bars for Route C. From the graph, we can see that the green bar (representing on-time arrivals) is approximately three times taller than the red bar (representing late arrivals) for Route C.
To calculate how many times more likely you are to be on time than late if you take Route C, we need to find the ratio of the heights of the green and red bars:
Ratio = height of green bar / height of red bar
Looking at the segmented bar graph, we can see that the height of the green bar for Route C is approximately 0.45, and the height of the red bar is approximately 0.15.
Ratio = 0.45 / 0.15

If (x -1) is a factor of the polynomial f(x) = 4x²- 4x² - x - K, where K is a Constant.
1. What is the Value of K?
2. What are the roots of the equation
Answer:
If (x-1) is a factor of the polynomial f(x) = 4x² - 4x² - x - K, then we know that (x-1) divides evenly into the polynomial, which means that the polynomial can be written as:
f(x) = (x-1)(ax + b)
where a and b are constants that we need to determine. We can use the distributive property to expand this expression and equate it with the original polynomial:
f(x) = (x-1)(ax + b) = 4x² - 4x - K
Expanding the left side of the equation, we get:
ax² + bx - ax - b = ax² - (a-b)x - b = 4x² - 4x - K
Now we can equate the coefficients of the like terms on both sides of the equation.
The coefficient of x^2 on the left side is a, and on the right side it is 4. Therefore, we have:
a = 4
The coefficient of x on the left side is b - a, and on the right side it is -4. Therefore, we have:
b - a = -4
Substituting a=4, we get:
b - 4 = -4
Solving for b, we get:
b = 0
So the polynomial can be written as:
f(x) = (x-1)(4x + 0) = 4x² - 4x
Therefore, K = 0.
To find the roots of the equation, we need to set f(x) = 0 and solve for x:
4x² - 4x = 0
Factor out 4x:
4x(x - 1) = 0
So the roots of the equation are x = 0 and x = 1.

the cost of day old donuts after the discount is $4.95.
what is discount?A discount is a decrease in the cost of a good or service. Discount is the reduction in the price of goods or services offered by shopkeepers at the marked price.
Discounts are offers or rebates made to customers on the marked-down prices of goods. We come across phrases like cost price, tagged price, discount, and selling price when making a purchase. Shop owners give discounts to customers to encourage product sales. Let's examine the connections between these concepts.
The formula to calculate the discount is:
Discount = List Price - Selling Price
Discount (%) = (Discount/List Price) × 100
the discount is 40% ⇒0.4
customer buys 3 donuts.
price of 1 donut = $2.75
total cost for 3 donuts= $2.75 x 3 = $8.25
discount for 1 donut= [tex]\frac{0.4}{100}* 2.75[/tex]=$1.1

Hi I need help finding the degree measure of Radian on a triangle with hypotenuse =7 and opposite =3
Answer:
24.6 degrees.
Step-by-step explanation:
To find the degree measure of the radians in a right triangle with hypotenuse = 7 and opposite = 3, we need to use trigonometric ratios. Since the opposite and hypotenuse are given, we can use the sine ratio.
sin(θ) = opposite/hypotenuse
sin(θ) = 3/7
Now we need to find the angle measure θ. We need to use the inverse sine or arcsine function to do this.
θ = sin^-1(3/7)
θ ≈ 0.429 radians
To find the degree measure, we must convert radians to degrees by multiplying by 180/π.
θ ≈ 0.429 x 180/π
θ ≈ 24.6 degrees
Therefore, the degree measure of the radians in the given triangle is approximately 24.6 degrees.
A car is purchased for $19,500. After each year, the resale value decreases by 20%. What will the resale value be after 3 years? Use the calculator provided and round your answer to the nearest dollar.
The resale value of the car after 3 years is $9,984.
How to find the resale value after 3 years?Since the resale value decreases by 20%. Thus, the resale value of the car will be 80% of its original value.
After the first year, the resale value of the car will be 80% of its original value:
Resale value after 1 year = 80/100 * $19,500 = $15,600
After the second year, the resale value of the car will be 80% of its value after the first year:
Resale value after 2 years = 80/100 * $15,600 = $12,480
After the third year, the resale value of the car will be 80% of its value after the second year:
Resale value after 3 years = 80/100 * $12,480 = $9,984

Describe what happens as the number of sides of the bases of a prism increases.
THIS IS NOT COLLEGE LEVEL IT IS MIDDLE SCHOOL
Answer:
As the number of sides of the bases of a prism increases, the shape of the prism becomes more complex and closer in form to a cylinder. For example, a prism with two identical polygonal bases, such as a rectangular prism or a triangular prism, will have a more blocky or pyramidal shape. However, as the number of sides of the base increases, the shape of the prism becomes more cylindrical and less pyramidal in appearance. This is because the more sides a polygon has, the more closely it approximates a circle, and the cross-section of the prism becomes more circular in shape.
When the number of sides of the base of a prism increases, the prism becomes more like a cylinder.
The value of y is directly proportional to the value
of x. If x = 8, then y = 12. What is the value of x when y = 30?
Answer:
If the value of y is directly proportional to the value of x, we can use the formula for direct variation to find the value of x when y = 30. The formula for direct variation is:
y = kx
where k is the constant of proportionality.
To find the value of k, we can use the values given in the problem:
y = kx
12 = k(8)
Solving for k, we get:
k = 12/8 = 3/2
Now that we know k, we can use the formula for direct variation to find the value of x when y = 30:
y = kx
30 = (3/2)x
Solving for x, we get:
x = (30)/(3/2) = 20
Therefore, when y = 30, x = 20
4/7 of the length of a car ride is 8 miles. How many miles is the whole car ride ?
