Determine the measurements of 1 angle in the figure
Answers
All angles of a triangle add up to 180 degrees.
Angle 1 + 72 + 40 = 180
Angle 1 + 112 = 180
Angle 1 = 180 - 112
Angle 1 = 68
Thus, you answer should be 68
x/2-1=3 what is X PLEASE HELPPPPPPPPPPP
Answers
x / 2 - 1 = 3
Add 1 to both sides.
x / 2 = 4
Multiply both sides by 2.
x = 8
Now lets put in 8 for x in our original equation:
8 / 2 - 1 = 3
4 - 1 = 3
3 = 3
This is correct, therefore we know x = 8.

A trigonometric graph has the equation y=2cos2∅. State the amplitude of this graph?
Answers
Answer:
amplitude = 2
Step-by-step explanation:
Given
y = a cosbx
amplitude = | a | , period = [tex]\frac{2\pi }{b}[/tex]
y = 2cos2∅
with amplitude = | 2 | = 2
Answer:
[tex]\displaystyle 2[/tex]
Step-by-step explanation:
[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A|[/tex]

Help with my work mane please im bwgging you
Answers
Answer:
A) 1, 4, 5, 9, 14, 23, 37
B) 2, 4, 6, 10, 16, 26, 42
Step-by-step explanation:
1. The Fibonacci sequence states that each number is the sum of the two numbers before it.
For example, if we have the first two numbers of a sequence as 5 then 6, the next term would be 11.2. Given the information above, let's solve the question.
-> A: 9 + 14 = 23, 14 + 23 = 37
The next two terms for sequence A are 23 then 37-> B: 10 + 16 = 26, 16 + 26 = 42
The next two terms for sequence B are 26 then 42Therefore, the answer is:
A) 1, 4, 5, 9, 14, 23, 37
B) 2, 4, 6, 10, 16, 26, 42
A gallon is 128oz. An airplane can carry 1,445 gallons of fuel. Write the number of ounces of fuel the plane can carry.
Answers
Step-by-step explanation:
one gallon is 128oz.
1445 gallons are how many Oz?
that applies the same principle as every-day situations like "every guest will eat 2 dumplings. 12 guests are coming, so how many dumplings do I have to prepare ?"
or totally simple : "every child will get one gift. 4 children are coming, so how many gift do I have to prepare ?"
it all works with multiplication. it is the ultimate application for multiplication.
that is why we use "times" in normal language as in mathematical terms. like "it takes 3 screws to mount a leg to a table. and the table needs 4 legs. how many times do I need to fasten a screw to finish one table ?" well, 4 times 3 or 4×3 = 12 times.
and so, the answer to the original question is then I need to take the amount of one gallon 1445 times.
128 × 1445 = 184,960oz

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels 18 miles per hour slower than the eastbound train. If the two trains are 300 miles apart after 2 hours, what is the rate of the westbound train? Do not do any rounding.
Answers
Answer:
66 mph
Step-by-step explanation:
w = e - 18
2w + 2e = 300
2 (e - 18) + 2e = 300
2e - 36 + 2e = 300
4e - 36 = 300
4e = 300 + 36 = 336
e = 84 mph
w = 66 mph
The westbound train is travelling at 66 mph

Answers
Answer:
Yes, with some change to spare.
Step-by-step explanation:
He has 20$. Take 1/5 of it, it's 4$ (because 4x5 = 20), so he will be left with 16$. He owes less than this, 15$, so he can repay his debt in full and have still 1$ left.

Step-by-step explanation:
Looks like a typo in the question
To get the unit rate, divide the miles by the hours
Unit rates
1000 miles in 2 hours = 1000/2 = 500
I'm guessing you meant 100 miles not 1000 miles
100 miles in 2 hours = 100/2 = 50
why does the formula for area of a circle make sense
Answers
Answer:
Step-by-step explanation:
The usual definition of pi is the ratio of the circumference of a circle to its diameter, so that the circumference of a circle is pi times the diameter, or 2 pi times the radius. The animation above shows that a circle can be cut and rearranged to closely resemble a parallelogram (with height r and base pi times r) of area pi times the square of the radius. By dividing the circle into more than eight slices, the approximation obtained in this manner would be even better. By dividing the circle into more and more slices, the approximating parallelograms approximate the area of the circle arbitrarily close. This give a geometric justification that the area of a circle really is "pi r squared".

One angle of a right triangle measures 60°. What is the measure of the other acute angle?
Answers
Answer:
30°
Step-by-step explanation:
as sum of angles = 180°

a= 18; b= 48; c= 88. Please note that even half these value work (9, 24, 44) or any multiple of these (9k, 24k, 44k, with k a positive integer)
Step-by-step explanation:
Let's go easy, and pick b to be 6x8, to make things easy for us. Maybe even 6x4 could work, 12x8 will totally work, but this is the simplest choice.
Now on the first proportion [tex]a:48=3:8 \rightarrow 8a = 48\times3 \rightarrow a = 18[/tex]
From the second proportion [tex]48:c=6:11 \rightarrow 6c = 48\times 11 \rightarrow c = 88[/tex]
