The denominator of a fraction is three more than twice the numerator. If both numerator and denominator are decreased by one, the simplified result is 7/16. Find the original fraction.
Answers
Numerator = n = x
denominator = d = 2n + 3
New Condition
(x - 1) /(2x + 3 - 1) = 7 / 16
(x - 1) / (2x + 2) = 7 / 16
Cross multiply and solve
16*(x - 1) = 7 * (2x + 2) Remove the brackets.
16x - 16 = 14x + 14 Add 16 to both sides.
16x = 14x + 30 Subtract 14x from both sides.
2x = 30 Divide by 2
x = 15
You really should check this.
Original fraction

Now subtract 1 from the top and bottom.

what am i supposed to do??
Answers
16x - 7 = 8x + 2 + 10x - 19 ===> 16x -7 = 18x - 17
16x - 16x - 7 = 18x - 16x - 17 ===> -7 = 2x - 17
-7 + 17 = 2x - 17 + 17 ===> 10 = 2x ======> 5 = x
Plug x in to each equation.
Angle P: 8(5) + 2 = 42 deg, Angle Q: 10(5) - 19 = 31
The sum of interior angles = 180. 180 - 42 -31 = 107 deg (angle of PRQ)
To check that line other angle : 16(5) -7 = 73 deg + 107 = 180 deg
A 25-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground 6 feet from the base of the building. How high up the wall does the ladder reach?
Round to the nearest hundredth
Answers
hope it helps
The ladder reaches a height on the wall of approximately 24.29 feet.
Explanation:To find the height on the wall that the ladder reaches, we can use the Pythagorean theorem. The ladder, the wall, and the ground form a right triangle. The ladder is the hypotenuse, the distance from the base of the building to the ladder is one leg, and the height on the wall that the ladder reaches is the other leg. Using the Pythagorean theorem, we have:
a² + b² = c²
where a is the distance from the base of the building to the ladder (6 feet), b is the height on the wall, and c is the length of the ladder (25 feet).
Solving for b, we have:
b = √(c² - a²)
Substituting the given values, we get:
b = √(25² - 6²) = √(625 - 36) = √589 ≈ 24.29 feet
Therefore, the ladder reaches a height on the wall of approximately 24.29 feet.

see below for a drawingthe area of one of the trapezoids is 20 units²Step-by-step explanation:
No direction or other information about the desired parallelogram is given here, so we drew one arbitrarily. Likewise for the segment cutting it in half. It is convenient to have the bases of the trapezoids be the sides of the parallelogram that are 5 units apart.
The area of one trapezoid is ...
A = (1/2)(b1 +b2)h = (1/2)(3+5)·5 = 20 . . . . square units
The sum of the trapezoid base lengths is necessarily the length of the base of the parallelogram, so the area of the trapezoid is necessarily 1/2 the area of the parallelogram. (The area is necessarily half the area of the parallelogram also because the problem has us divide the parallelogram into two identical parts.)

C.building insurance
D.liability insurance
Answers
Option A is correct answer.
Step-by-step explanation:
Insurance that pays for damages to houses or businesses is called - property/homeowners insurance.
The homeowners insurance protects ones personal property. This insurance deals with the insurance covers for repairing or replacing ones home and belongings, if they are damaged by fire or theft.
It also covers for the damage to others property inflicted by you or when any visitor damages your property.
Final answer:
Insurance that pays for damages to houses or businesses is called property/homeowners insurance, which covers a range of risks and includes liability coverage. The policy generally provides cash value or replacement value for the insured property and possessions.
Explanation:
The insurance that pays for damages to houses or businesses is called property/homeowners insurance. This type of insurance is crucial as it provides a safety net against various risks such as fire, wind damage, theft, and falling trees. Besides covering damages to the physical structure of a home, homeowners insurance often includes liability coverage, which protects the homeowner up to a certain amount if someone is injured on their property, except in cases where the law is being broken.
Furthermore, it is worth noting that an insurance policy generally has a cash value. If a house is destroyed, the policy will pay out the current value of the house. A replacement value policy is recommended, as it will adjust the payout based on inflation and cover the cost to replace the home, including other structures like garages and pools as well as personal property within the house.
if Trigg spends 23.50 on gas, what is the total distance the boys could travel
Answers
To determine the total distance Trigg could travel with $23.50, you divide this amount by the cost per gallon of gas and then multiply by the car's MPG. Using an MPG of 27 and a gas price of $2.86 per gallon as example figures, Trigg could travel approximately 221.859 miles.
To calculate the total distance Trigg could travel with $23.50 spent on gas, we need to know the car's fuel efficiency (miles per gallon) and the current gas price per gallon. Since this information isn't provided directly in your question, let's use the example information provided. Assuming a car gets 27 miles per gallon and gas costs $2.86 per gallon, we first calculate how many gallons Trigg can buy with $23.50:
Divide $23.50 by the cost of a gallon of gas ($2.86) to find out how many gallons he can purchase:$23.50 / $2.86 = 8.217 gallons (approximately).Multiply the number of gallons by the fuel efficiency of the car to find out the total distance: 8.217 gallons x 27 miles per gallon = 221.859 miles (approximately).
Therefore, with $23.50 and the given fuel efficiency and gas price, Trigg could travel approximately 221.859 miles.

Jenny live 6 1/4 miles from school. Raymond lives 5 1/2 miles from school. How much farther from school does Jenny live then Raymond? Write an equation and solve it
Answers
6 1/4 - 5 2/4= 3/4
The answer is 3/4.
To find out how much farther Jenny lives from school than Raymond, we subtract Raymond's distance from Jenny's, converting both to improper fractions to subtract easily, resulting in Jenny living 3/4 of a mile farther than Raymond.
Explanation:The question asks how much farther from school Jenny lives compared to Raymond. Jenny lives 6 1/4 miles from school, and Raymond lives 5 1/2 miles from school. To find out how much farther Jenny lives from the school than Raymond, we can write an equation and solve it.
Let ‘d’ represent the difference in distance between how far Jenny lives from the school and how far Raymond lives from the school. The equation can be written as:
d = 6 1/4 miles - 5 1/2 miles
To solve this, we first convert the mixed numbers to improper fractions. Therefore, 6 1/4 miles becomes 25/4 miles, and 5 1/2 miles becomes 11/2 miles. Our equation now looks like this:
d = 25/4 miles - 11/2 miles
We need a common denominator to subtract these fractions, which is 4 in this case. So we convert 11/2 miles into 22/4 miles. The revised equation is:
d = 25/4 miles - 22/4 miles
When we subtract 22/4 from 25/4, we find d = 3/4 miles. Therefore, Jenny lives 3/4 of a mile farther from school than Raymond.
Elizabeth lives in San Francisco and works in Mountain View. In the morning, she has 333 transportation options (take a bus, a cab, or a train) to work, and in the evening she has the same 333 choices for her trip home. If Elizabeth randomly chooses her ride in the morning and in the evening, what is the probability that she'll use a cab exactly one time?
Answers
Now, P(using cab exactly once) = P(cab at morning and no cab in the evening) + P(no cab at morning and cab in the evening)
= P(cab, no cab) + P(no cab, cab)

Tom can whitewash a fence at a rate of six square feet per minute. Huck can whitewash a fence at a rate of ten square feet per minute. Tom starts painting her fence, and five minutes later, Huck starts to help Tom. When they finish painting the fence, each person has painted half of the fence. How many square feet is the fence?
Answers
T = Tom = 6 square feet a minute.
The "distances" they have to go are equal since both do the same amount.
R_Tom * time_tom = R_Huck * time huck
6* (t) = 10 * (t - 5)
6t = 10t - 50 Add 50 to both sides
6t + 50 = 10t Subtract 6t from both sides.
50 = 4t Divide by 4
50/4 = t
12.5 = t
This means that tom was working for 12.5 minutes. He does 6 square feet a minute The amount of fence he does is 12.5 * 6 = 75 square feet.
Since Huck does the same amount the total is 75 * 2 = 150 square feet total.

The mass in a pendulum clock completes one complete swing in 1.00 s . what is the length of the rod?
Answers
[tex]T=2 \pi \sqrt{ \frac{L}{g} } [/tex]
Where L is the length of the pendulum and [tex]g=9.81 m/s^2[/tex] the gravitational acceleration.
Re-arranging the formula and using T=1.0 s, we find the length of the pendulum:
[tex]L= \frac{T^2g}{4 \pi^2}=0.25 m [/tex]
The length of the pendulum or rod in a pendulum clock that completes one swing in 1.00 seconds is approximately 0.25 meters, or 25 centimeters.
Explanation:The time taken by the pendulum to complete one full swing is also known as its period, denoted by T. You indicated that in this case the pendulum completes one swing in 1.00 seconds. To determine the length of the pendulum, or rod, we use the formula for the period of a simple pendulum, T=2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity (approximately 9.8 m/s² on Earth).
Setting T to 1.00 seconds and g to 9.8 m/s², we can solve this equation for L:
L = (T² * g) / 4π²
Substituting the given values:
L = (1.00² * 9.80) / 4π²
This gives us a pendulum length of approximately 0.25 meters, or 25 centimeters.
