Ok this is my last one
Answer:
A. 54 m^2
Step-by-step explanation:
You can do cross multiplication: [tex]\frac{4}{6}[/tex]×[tex]\frac{x}{9}[/tex]
4*9 = 6*x
36 = 6x
x = 6
That is the Width in m, so all you need to do is find the area!
Area = L * W
Area = 9 * 6
Area = 54

Solve for the missing side length. Round to the nearest tenth.
х
40°
20
Answer:
x=20
Step-by-step explanation:
If there is a 90° angle, that means the 2 sides connecting it must be the same. Therefore, side x is equal to 20 since it is equal to the other side connecting the angle.

A straight line passes through 0 and (2, 6)
Circle the equation of the line
[1 mark]
Answer:
y = 3x
Step-by-step explanation:
To find out what the equation is here, divide the y coordinate by the x coordinate of the point given (2, 6). Here divide 6 by 2. That would equal 3. That means that the y coordinate is 3 times as much as the x coordinate. As a result we can make the equation y = 3x out of what we now know.

x = 23 and y = 20
Step-by-step explanation:
find 21.4 of 855 percent equation
Answer:
21.4% of 855=182.97
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 855 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 855 is 100%, so we can write it down as 855=100%.
4. We know, that x is 21.4% of the output value, so we can write it down as x=21.4%.
5. Now we have two simple equations:
1) 855=100%
2) x=21.4%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
855/x=100%/21.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 21.4% of 855
855/x=100/21.4
(855/x)*x=(100/21.4)*x - we multiply both sides of the equation by x
855=4.67289719626*x - we divide both sides of the equation by (4.67289719626) to get x
855/4.67289719626=x
182.97=x
x=182.97
now we have:
21.4% of 855=182.97
Hope this helped :)

Answer:
log(35)/log(7)
Step-by-step explanation:
The change of base formula is ...
[tex]\log_b(a)=\dfrac{\log(a)}{\log(b)}[/tex]
You have b=7, a=35, so the rewrite is ...
[tex]\log_7(35)=\boxed{\dfrac{\log(35)}{\log(7)}}[/tex]
In ΔMNO, n = 85 inches, o = 10 inches and ∠M=56°. Find the length of m, to the nearest inch.
Answer:
80
Step-by-step explanation:
Delta math math
The length of m in triangle MNO is approximately 80 inches.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.
In ΔMNO, n = 85 inches, o = 10 inches, and ∠M=56°.
In this case, we are given the lengths of sides n and o and the measure of angle M. We can use the law of cosines to solve for the length of side m:
⇒ m² = n² + o² - 2 × n × o × cos(∠M)
We are given that n = 85 inches, o = 10 inches, and ∠M = 56°. We can use these values to solve for m:
⇒ m² = 85² + 10² - 2 × 85 × 10 × cos (56°)
We can use a calculator or look up the value of cos 56° to find that it is approximately 0.6. Plugging this value into the formula above gives us:
⇒ m = 79.8397 ≈ 80 inches
Therefore, the length of m in triangle MNO is approximately 80 inches to the nearest inch.
