what is the difference between 2/4 and 4/9
Answer:
Step-by-step explanation:
Here's how to subtract 4/9 from 2/4:
[tex]\frac{2}{4} -\frac{4}{9}[/tex]
Step 1:
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 2 by 9, and get 18.
Then we multiply 4 by 4, and get 16.
Next we give both terms new denominators -- 4 × 9 = 36.
So now our fractions look like this:
[tex]\frac{18}{36} -\frac{16}{36}[/tex]
Step 2
Since our denominators match, we can subtract the numerators.
18 − 16 = 2
So the answer is:
[tex]\frac{2}{36}[/tex]
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
[tex]\frac{2}{36}[/tex]÷2=[tex]\frac{1}{8}[/tex]
Let's try dividing by 2 again...
No good. 2 is larger than 1. So we're done reducing.
There you have it! The final answer is:
[tex]\frac{1}{8}[/tex]

Answer: 3.8
Step-by-step explanation:first, you need to figure out what side you’re looking for. Side AC is opposite of the angle you’re given. They also give you length of side AB which is 4. That is the hypotenuse (side directly across from right angle). So, you have the hypotenuse, and need the find the opposite side measure. Which option uses opposite and hypotenuse? That’s Sin. So, you would do: sin70 = ? / 4.
sin (of given angle)= opposite / hypotenuse.
Sin (70 degrees) = ? / 4
Then you solve for “?”
Type sin70 into your calculator, then multiply both sides by 4 to get “?” by itself. You should get 3.758770483, which rounds to 3.8

Comparing lengths of sharks horn shark is 2 3/4 feet long a blue shark is 4 times longer what is the answer
Answer:
11
Step-by-step explanation:
Change 2 3/4 to a mixed number.
11/4
Then multiply
11/4 • 4
Get rid of common denominators. Which are the 4s.
So you're left with 11.
Or you could just turn 4 into 4/1.
Which would be 44/4.
Which simplifies to 11.
Hope this helps.

Answer:
x = 11.8
Step-by-step explanation:
hypotenuse = 12
1 leg = 10 - 8 = 2
Formula:
a² + b² = c²
a² + 2² = 12²
a² + 4 = 144
a² = 144 - 4
a² = 140
[tex]\sqrt{a^2} =\sqrt{140}[/tex]
a = 11.8
Answer:
x = 11.8
Step-by-step explanation:
hypotenuse = 12
1 leg = 10 - 8 = 2
Formula:
a² + b² = c²
a² + 2² = 12²
a² + 4 = 144
a² = 144 - 4
a² = 140

Wayne types about 50 words per minute.A typical double spaced page contains 500 words.how long doe sit take Wayne to type 8 1/2 pages?
Answer:
Step-by-step explanation:
50t=500(8.5)
t=10(8.5)
t=85 minutes
Answer: 85 minutes
Step-by-step explanation:
First, find how many minutes it takes for Wayne to type a page containing 500 words. 500/50= 10 minutes
You then multiply that by 8
8(10)= 80 minutes to type 8 pages.
Now find how many words are in half a page.
500/2=250 words
Divide that by the amount of words Wayne can type per minute. 250/50= 5
Add that to the amount of minutes it took to type 8 pages. 85 minutes
Which is also 1 hour 25 minutes

Find the surface area of each figure. Round your answers to the nearest hundredth, if necessary
Answer
238π yd^2
Step-by-step explanation:
here's your solution
=> height of cylinder = 10 yd
=> radius of cylinder = 7 yd
=> formula to calculate surface area = 2πr(h + r)
=> putting the value of height and radius in formula
=> SA = 2*22/7*7(10+7)
=>. SA = 2*22*17
=> SA = 748 yd.sq

4,400,000 in scientific notation.
Answer:
4.4 * [tex]10^{6}[/tex]
Step-by-step explanation:
Answer:
4.4 x 10^6
Step-by-step explanation:
The decimal in scientific notation needs to be less than 10, so in this case the decimal has to be 4.4.
After you place the decimal you should have, 4.400000.
Count how much decimal spaces you have to jump in order to get to the end of the number overall, in this case, it is 6 to the 10th power.
So the answer would be, 4.4 x 10^6

Need help with this. Find the value of each variable.
Answer:
Step-by-step explanation:
By applying sine rule in ΔACD,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(30°) = [tex]\frac{CD}{AD}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{z}{24}[/tex]
z = [tex]8\sqrt{3}[/tex]
By applying cosine rule in ΔACD,
sin(30°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(30°) = [tex]\frac{AC}{CD}[/tex]
[tex]\frac{1}{2}=\frac{AC}{24}[/tex]
AC = 12
By applying tangent rule in ΔACB,
tan(45°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
1 = [tex]\frac{AC}{BC}[/tex]
y = 12
By applying sine rule in ΔACB,
sin(45°) = [tex]\frac{BC}{AB}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{y}{x}[/tex]
x = y(√2)
x = 12√2

Answer:
B : inscribed angle theorem
Step-by-step explanation:
The missing reason in step 5 is; Inscribed angle theorem.
Inscribed angle theoremWithin the context of circle geometry, an inscribed angle is the angle formed in the interior of a circle as a result of the intersection of two chords on the circumference of the circle.
Put differently, an inscribed angle is defined by two chords of the circle sharing an endpoint.
Ultimately, since the chords LM and MN intersect on the circumference, with LM being the diameter of the circle, then the measure of angle LMN is 90°.
