It takes Frank 2 hours to build a fence. It takes Tom 9 hours to build the same fence. How long would it take to build the fence if Frank and Tom built the fence together?
Answer:
5 1/2 hours
Step-by-step explanation:
You would have to add 2 and 9 and then divide by 2. (Find the average of the two)
2 + 9 = 11
11 / 2 = 5.5
So if you add their times then divide you receive and average of five and a half hours.

A 50 loot ladder is leaning against a building. If the base of the ladder is 35 feet from the base of the building, how far up the building is does the ladder rest? Round to the nearest hundredth (two decimal places)
Answer:
The ladder is 35.71 feet up the building
Step-by-step explanation:
Here, we want to calculate how far up the building is the ladder placed
We should picture a right angled triangle with hypotenuse 50 and one of the other sides as 35
To find the height in this case, we proceed to use Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides
In this case, let the height be
50^2 = 35^2 + h^2
h^2 = 50^2-35^2
h^2 = (50+35)(50-35)
h^2 = (85)(15)
h^2 = 1275
h = square root of 1275
h = 35.71 ft
Gavin has 50 tokens and continues to ride the roller coaster three times every hour Gibson has 12 tokens and finds two more tokens on the ground every hour how long until they have the same amount of tokens?
Answer:62
Step-by-step explanation: I just did it and got it right
They have the same amount of tokens after t = 7.6 hours.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Since Gavin initially has 50 token and rides the roller coaster three times per hour, he uses 3 token per hour.
So, a number of token he losses after t hours is 3 token per hour × t hours = 3t.
Thus, the number of tokens left after t hours is T = 50 - 3t
Since Gibson initially has 12 tokens and find two tokens on the ground per hour, he gains 2 tokens per hour.
So, number of token he gains after t hours is 2 token per hour × t hours = 2t.
Thus, the number of tokens he has after t hours is T' = 12 + 2t
To find the time t when they will have the same tokens, T must be equal to T', that is T = T'.
So, 50 - 3t = 12 + 2t
Now collecting like terms, we have
50 - 12 = 3t + 2t
38 = 5t
Then dividing both sides by 5, we have
t = 38/5
t = 7.6 hours
Hence, they have the same amount of tokens after t = 7.6 hours.

Given that these two triangles are similar, what is the measure of L???
Answer:
35°
Step-by-step explanation:
Each triangle has a total degree of 180° so you know that one triangle has degrees of 90°&55° then you can subtract that from 180 to find out. But since they are similar they have to have the same angles and the first triangle tells you the missing angle.
Sarah has a brother who is 5 years younger than herself and another brother who is 8 years younger than herself. She observes that the product of her brothers ages is equal to the age of her 40 year old father. How old is Sarah? How do we setup an equation for this using null factor law presumably.
Answer:
Sarah is 13 years old
Step-by-step explanation:
Represent Sarah's age with S
Her first brother's age with F
Her second brother's age with B
So, we have:
From the first statement, we have:
[tex]S - F = 5[/tex] ---- (1)
From the second, we have:
[tex]S - B = 8[/tex] ---- (2)
The product of their ages is 40.
First, we make F the subject in (1) and B the subject in (2)
[tex]F = S - 5[/tex]
[tex]B = S - 8[/tex]
Their product is represented as follows:
[tex]F * B = 40[/tex]
Substitute values for F and B
[tex](S - 5) * (S - 8)=40[/tex]
Open bracket
[tex]S^2 - 5S -8S + 40 = 40[/tex]
[tex]S^2 - 13S + 40 = 40[/tex]
Subtract 40 from both sides
[tex]S^2 - 13S = 0[/tex]
Factorize:
[tex]S(S - 13) = 0[/tex]
Split:
[tex]S = 0[/tex] or [tex]S - 13 = 0[/tex]
But Sarah's age can't be 0 because she has two younger brothers.
So, we stick to
[tex]S - 13 = 0[/tex]
Make S the subject
[tex]S = 13[/tex]
Hence, Sarah is 13 years old
Noah's oven thermometer gives a reading that is 2% greater than the actual temperature if the actual temperature is 350°F what was the motor reading be
Answer:
357°FStep-by-step explanation:
Step one:
given data
actual reading= 350°F
thermometer reading 2% of the actual reading
Step two:
Required:
The thermometer reading
let us find 2% of 350°F
2/100*350°
=0.02*350
=7°F
Hence the thermometer reading is 7°F greater than 350°F
The thermometer reading is 350+7=357°F
The smiths went to Larosa's for dinner and spent $42.50 on dinner. There is a 6.5% tax and they want to give a tip of 20% before the tax is added. What is the total price of their bill?
Answer:
Step-by-step explanation:
cost of dinner = $42.5
Tax = 6.5%
Tip = 20%
Total amount percent on food = 26.5%
Amount paid on the original price = 26.5% of $42.5
Amount paid on the original price = 0.265*42.5 = $26.5625
Total price of the bill = $42.5 + $26.5625
Total price of bill = $69.0625
