Answer:
Step-by-step explanation:
For correct scientific notation, we need to have 1 number to the left of the decimal, and everything else to the right. Since our number is already less than 1, the exponent representing the number of places we move the decimal will be negative. We have to move the decimal 5 places to the right to get the 5 to the left of the decimal and everything else to the right, making this:

Find the value of each variable using sine and cosine. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
copy and paste the above on to your computer for future reference
n= Hyp
m= adj
8 = Opp
∠=50°
sin(50) = 8/n
n = 8/sin(50)
n = 10.44325
n= 10.4 ( to nearest 10th)
tan(50) = 8 / m
m = 8 / tan(50)
m = 6.712797
m = 6.7 ( to nearest 10th )

What is the approximate area of the circle shown below?
A. 50 cm2
B. 201 cm2
C. 804 cm2
D. 25 cm2
Answer:
Hello! answer: B.
attention: im using 3.14 for pi so answers may vary. ok so in this picture we are provided with the diameter to find area we can do radius × radius × 3.14
16 ÷ 2 = 8 8 × 8 = 64
64 × 3.14 = 200.96 When you round this up it's 201 so approximately the answer would be B. Hope that helps!

second inequality :
x - y ≤ -2
(7x+1)(2x−3)=0 solve for roots
Answer:
x = - [tex]\frac{1}{7}[/tex], x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
(7x + 1)(2x - 3) = 0 ← in standard zero product form
Equate each factor to zero and solve for x
7x + 1 = 0 ⇒ 7x = - 1 ⇒ x = - [tex]\frac{1}{7}[/tex]
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]
Answer:
x = - 1 / 7 and x = 3 / 2
Step-by-step explanation:
14x2 - 21 x + 2x- 3 = 0
14x2 - 19x -3 = 0
x = 1 9 + 23 / 28 = 3 / 2
x = 19 - 23 / 28 = - 1 / 7
7x + 1 = 0 ⇒ 7x = - 1 = -1 / 7
2x - 3 = 0 ⇒ 2x = 3 = 2/ 3
Hope this answer helps you :)
Have a great day

Find the RATIO and the EXACT VALUE of the given Csc A.
Answer:
Step-by-step explanation:
Take angle A as reference angle
using cosec rule
cosec A=hypotenuse/opposite
cosec A=13/5
cosec A=2.6
A=cosec 22.5
A=22.5
for ratio,
cosec A=13/5

Step-by-step explanation:
Sorry if wrong
Answer:
In this case, D
Step-by-step explanation:
Sin(30+60)=0.8939966636 which can be rounded to 0.89.
Now that we got that out of the way, we supposedly can follow the process of elimination.
It's clearly not A since we know the answer isn't equivalent to zero.
1/2 equals 0.5, meaning B's also not it.
We also know the answer isn't D, since 0.89 does not equal 1.
That only leaves C. Yet when check, just in case, √3/2 equals 1.22474487, meaning that's not the answer.
We've eliminated every answer so far, meaning we should go back and check our work. As I stated earlier, 0.8939966636 can be rounded to 0.89, but it can also be rounded to 1. Meaning, the closest answer to what we're looking for is D.
Of course, there could always be an error in the question itself, but unfortunately, there's no way to confirm that without asking your instructor or tutor.
I hope that helps.

How do you find the value for x?
Find the value of x ?
Answer:
x = 27
Step-by-step explanation:
Both angles together form 180 degree.
Set your formula up as
180 = (5x+2) + (x + 16)
180 = 5x + 2 + x + 16
180 = 6x + 18
180 - 18 = 6x
162 = 6x
162/6 = x
27 = x
Answer:
27°
Step-by-step explanation:
They are in a straight line , therefore ,
> 5x + 2 + x + 16 = 180
> 6x + 18 = 180
> 6x = 180 - 18
> 6x = 162
> x = 27
Hence the required answer is 27°
Which equation can be used to find A, the area of the parallelogram shown?
A parallelogram with a base six meters, height seven meters, and diagonal side length eleven meters
A = 6 × 7
A = 6 × 11
A = 12 × 6 × 7
A = 12 × 6 × 11
Answer:
A = 6 x 7
Step-by-step explanation:
To find the area of a parallelogram we use the equation of Area = base x height. In this case since the base is 6 and the height is 7, we plus in these numbers for the variables (b x h) to get the area.

Solve for x. Show your work.
Answer:
x=6
Step-by-step explanation:
Both Angles are commentary and have a sum of 90
Therefore, set your formula up as
90 = 5x + (x + 54)
90 = 6x + 54
90 - 54 = 6x
36 = 6x
36/6 = x
6 = x

El volumen de un cubo, cuyos lados miden 4,5 cm corresponde a: A- 91 cm2 B- 91,1 cm C- 91 cm3
Answer:
La respuesta correcta es la opción C: 91 cm³.
Step-by-step explanation:
La fórmula del volumen de un cubo es la siguiente:
[tex] V = a^{3} [/tex]
En dónde:
a: es cada lado del cubo = 4,5 cm
Entonces, el volumen del cubo es:
[tex] V = a^{3} = (4,5 cm)^{3} = 91.1 cm^{3} \approx 91 cm^{3} [/tex]
Por lo tanto, la respuesta correcta es la opción C: 91 cm³.

A store owner has 31.2 pounds of candy. If he splits the candy equally into 6 boxes, how many pounds of candy will each box contain?
Answer:
5.2
Step-by-step explanation:
if you take 31.2 and divide it by 6 you will get 5.2
Answer:
5 1/5 pounds which equals 5.2 pounds
Step-by-step explanation:
31 2/10 = 31 1/5
31 1/5 = 156/5
156/5 ÷ 6 means 156/5 x 1/6
multiply numerators to get 156
multiply denominators to get 30
156/30 = 5 6/30 or 5 1/5 simplified
