Answer: She can read 1.2 chapters of her book in one hour.
Step-by-step explanation:
When we have a relation of: "doing something" in a given "amount of time"
The rate at which you can do that activity per unit of time is:
R = (how much you did)/(time it took)
In this case, we know that
"Tory reads 4/5 of a chapter in 2/3 of an hour"
Then the rate, in this case, could be calculated as:
R = (4/5 chapters)/(2/3 hour) = 1.2 chapter per hour.
This means she can read 1.2 chapters of her book in one hour.

In the center of a growing city is an old church and a high-rise office building separated by a plaza. Two surveyors are collaborating on the job of determining how high the tip of the church spire is above the plaza. Each surveyor has a theodolite mounted on a tripod. One surveyor is in the entrance way of the high-rise. The top of his tripod is 165cm above plaza level. The second surveyor is directly above the first, and (amazingly) the top of her tripod is exactly 100m above the top of her colleague's tripod. The first surveyor measures the angle of elevation of the tip of the spire as 50∘. The second surveyor measures the angle of depression of the tip of the spire as 30∘. (The diagram on the right is not drawn to scale. Points A and F are at plaza level. You'll have to supply all the necessary measurements on the diagram for yourself.)

Find the value of x : x/15 = 8/20
Answer:
x=6
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
x/15=8/20
Multiply both sides by 10:
x/15*10=8/20*10
Simplify:8/20*10
2x/3=4
Multiply both sides by 3:
3*2x/3=4*3
simplify:
2x=12
Divide both sides by 2:
2x/2=12/2
Simplify:
x=6

Anthony is a high school basketball player. How many points would Anthony score in a game if he made 8 three point shots and 2 two point shots? How many points would Anthony score in a game if he made xx three point shots and yy two point shots?
Answer:
try 6
Step-by-step explanation:
because it says 8 three point shots and 2 two point shots so its 3 times 2 ig
Answer:
Anthony would score 28 points.
If he made x 3 point shots and y 2 point shots = x*3 + y*2
Step-by-step explanation:
With Anthony making 8, 3 point shots you take 8 and multiply it by 3. This gives you 24. The 2, 2 point shots he made gives you 2 multiplied by 2 which gives you 4.
So taking x*3 + y*2, plug 8 into the x and 2 into the y. This gives you 8*3 + 2*2 = 24

Which type of function is represented by the equation 6y=2(x−5)
The type of the function that is represented by 6y = 2(x - 5) is a linear function
What are linear functions?Linear functions are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the type of the function?The equation of the function is given as
6y = 2(x - 5)
Divide both sides of the equation by 6
So, we have
y = 1/3(x - 5)
Open the bracket
y = 1/3x - 5/3
The form of the above equation is
y = mx + c
The equation represented by y = mx + c is a linear function
Hence, the type of the function that is represented by 6y = 2(x - 5) is a linear function

60 is 0.4% of what number? Use pencil and paper. Would you expect the answer to be a lot less than 60 , slightly less than 60 , slightly greater than 60 , or a lot greater than 60 ? Explain.
Answer:
15000
Step-by-step explanation:
0.4%=0.004
0.004x=60
x=60/0.004
x=15000
The number 60 is 0.4 percentage of the number 15,000
Given data ,
To find the number that 60 is 0.4% of, we can set up the equation:
60 = 0.4 percentage of x
To solve for x, we need to convert 0.4% to its decimal form, which is 0.004:
0.004 * x = 60
Now we can solve for x by dividing both sides of the equation by 0.004:
x = 60 / 0.004
Dividing 60 by 0.004 gives us:
On simplifying the equation , we get
x = 15,000
Therefore, 60 is 0.4% of 15,000.
Since 0.4% is a very small percentage (less than 1%), we would expect the answer to be a lot greater than 60. This is because when a small percentage is applied to a number, the result will be significantly larger than the original number. In this case, the number that 60 is 0.4% of is 15,000, which is a lot greater than 60.

The equation C(l) = l3 – l2 + l + 2.5 models the cost to mail a package as a function of its length. To the nearest quarter inch, approximately what is the length of a package that costs $11.00 to mail? Enter your answer as a decimal.
Answer:
2.25
Step-by-step explanation:
Given the cost model:
C(l) = l3 – l2 + l + 2.5
l = Length fo package
The length of a package that cost $11.00
11 = l³ - l² + l + 2.5
From the table given :
Length of mail which cost $11 will just be slightly greater Than 2 as the cost of 2 length mail cost 8.50
Taking l as 2.20
2.2^3 - 2.2^2 + 2.2 + 2.50 = 10.508
Taking a slightly higher value :
Put l = 2.25
2.25^3 - 2.25^2 + 2.25 + 2.50 = 11.078
Ww can conclude that the length of mail would be 2.25
Answer:

Aiko is selling books for $12 each. She wants to make more than $180 in book sales. The inequality 12b > 180 can be used to determine the number of books, b, she must sell in order to meet her goal. Which number line best represents the solution to the inequality?For which equation is x=5 a solution?
The third number line shows the inequality.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Aiko is selling books for $12 each. She wants to make more than $180 in book sales.
and, the inequality 12b > 180 can be used to determine the number of books, b.
Now, solving the inequality
12b > 180
b > 180/12
b > 15
Hence, the third number line shows the inequality.

Step-by-step explanation:
By applying angle addition postulate,
m∠ABC = m∠UBC + m∠ABU

m∠ABU = 145° - 75°
m∠ABU = 70°
