The measures of the three angles in a tri-
angle are in the ratio 1:2:3.
Answer:
30,60,90
Step-by-step explanation:
triangle are in the ratio 1:2:3.
So
Angles=X,2x,3x
X+2x+3x=180
6x=180
X=180/6
X=30
So angles are 30,60,90

Given the function f(x)=4(2)2, Section A is from x=1 to x=2 and section B is from x=3 to x=4. Part A: find the average rate of change of each section. Part B: How many times greater is the average rate of change of section B than section A? Explain why one rate of change is greater than the other.
Answer:
I found thois from someone else asking this queetion so gope it helps.
Step-by-step explanation:
I'm sure you want your functions to appear as perfectly formed as possible so that others can help you. f(x) = 4(2)x should be written with the " ^ " sign to denote exponentation: f(x) = 4(2)^x
f(b) - f(a)
The formula for "average rate of change" is a.r.c. = --------------
b - a
change in function value
This is equivalent to ---------------------------------------
change in x value
For Section A: x changes from 1 to 2 and the function changes from 4(2)^1 to 4(2)^2: 8 to 16. Thus, "change in function value" is 8 for a 1-unit change in x from 1 to 2. Thus, in this Section, the a.r.c. is:
8
------ = 8 units (Section A)
1
Section B: x changes from 3 to 4, a net change of 1 unit: f(x) changes from
4(2)^3 to 4(2)^4, or 32 to 256, a net change of 224 units. Thus, the a.r.c. is
224 units
----------------- = 224 units (Section B)
1 unit
The a.r.c for Section B is 28 times greater than the a.r.c. for Section A.
This change in outcome is so great because the function f(x) is an exponential function; as x increases in unit steps, the function increases much faster (we say "exponentially").

Ms. Twillie's class (25 students) and Ms. Grober's class (24 students) are off to the Field Museum for a field trip. Their expenses will be as follows: the program cost $10 per student; the bus costs $235.20; and the group will have lunch at a charge of $2.75 per student. If every student participates in the field trip, how much do each of students have to pay to go on the field trip?
Answer: Each student need to pay $ 17.55 to go on the field trip.
Step-by-step explanation:
As per given, Total students = 25+24 = 49
Program cost per student = $10
Bus cost = $235.20
Charge per student =$2.75
Total cost of trip = (Program cost+ Charge per student ) (Total students)+ Bus cost
Total cost of trip = $ [( 10 +2.75)(49) + 235.20]
= $[12.75(49)+235.20]
= $ [624.75+235.20]
= $ 859.95
Each student have to pay = (Total cost of trip ) ÷ (Total students)
= (859.95 ) ÷ 49
= $ 17.55 [approx.]
Hence, Each student need to pay $17.55 to go on the field trip.

A hole is being dug into the ground at a rate of 5.3 feet per minute. Write an integer to describe the depth of the hole after 15 minutes.
Answer:
79.5 feet
Step-by-step explanation:
5.3 per minute can also be written as the ratio 5.3:1. so if we have x:15, we can see that we've multiplied the right side by 15 so we have to do the same to the other side. 15 times 5.3 is 79.5. so thats your answer.
i hope this helps :))
The integer that explained the depth of the hole after 15 minutes is 79.5 feet.
Given that,
The rate should be 5.3 feet per minute.The time in minutes should be 15 minutes.So, the integer that explained the depth of the hole after 15 minutes is
[tex]= Rate \times time \\\\= 5.3 \times 15\\= 79.5\ feet[/tex]
Therefore we can conclude that the integer that explained the depth of the hole after 15 minutes is 79.5 feet.

draw the graph y = 4 x - 1 on the grid
Answer:
From the graph, it is also clear that at [tex]y=1[/tex], the value
of [tex]x=\frac{1}{2}[/tex].
Step-by-step explanation:
Given the equation
[tex]y = 4 x - 1[/tex]
The graph is attached below.
Putting [tex]y=1[/tex] in the equation to find the value of x
[tex]y = 4 x - 1[/tex]
[tex]1 = 4x-1[/tex]
[tex]2 = 4x[/tex]
[tex]x=\frac{2}{4}[/tex]

Which of the following decimal numbers are examples of terminating decimals?
0.6868
832.15902...
1,087.59014
9.12 5
23.7
14. 1
Answer:
First option
Sixth Option
Fifth Option
Third Option
Fourth Option
Step-by-step explanation:
Remember that a terminating decimal is a decimal that has a infinite amount of numbers after the decimal point. In this case we have 0.6868 which keeps going because it's repeating therefore it's a terminating decimal. Same rule goes for all the other options.

Find to 3 decimal places the value of t for the distribution for the following.
Area in the left tail 0.005 and n= 25.
Answer:
-2.797
Step-by-sep explanation:
The area in the left tail is the level of significance = [tex] \alpha = 0.005 [/tex]
n = 25
Since sample size, n, = 25,
Degree of freedom = n - 1 = 25 - 1 = 24
The value of t for the t distribution, that is the t critical value, would be:
[tex] -t\binom{n - 1}{\alpha} = -t\binom{9}{0.005} [/tex]
The t critical value can be gotten from the t-table at the intersection of the row representing 24 degrees of freedom and the [tex] t_{0.005} [/tex] column. This would give us -2.797
The t critical value of the left tail would be critical value is -2.797.

What is the cylinder?Cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. A cylinder has two bases and a curved surface. Total surface area = 2πr(r +h) square units. Curved surface area = 2πr h square units.
Given:
The given pool is in the shape of cylinder.
Volume of a pool = 2512 cubic feet
The height = 8 feet.
According to given question we have,
Volume of a pool=π[tex]r^{2} h[/tex]
2512 =π[tex]r^{2} *8[/tex]
Divide 8 on both sides we get,
[tex]r^{2}[/tex]=314/π
[tex]r=\sqrt{314/3.14} \\\\r=10 feet[/tex]
Therefore, the radius of a pool is 10 feet.
