Which expression shows 56x+40y-48z written as a product of the greatest common factor and one other factor
Answer:
Step-by-step explanation:
You have not provided the choices.
Factor each term into powers of primes and variables:
56x = 2³·7x
40y = 2³·5y
48z = 2⁴·3z
Greatest common factor = 2³ = 8
56x + 40y - 48z = 8(7x + 5y - 6z)
The side lengths of a 30-60-90 triangle are in the ratio 1 : 3:2. What is
sin 30°?
Answer:
1/2
Step-by-step explanation:
other answer was wrong
The value of sin30 is [tex]\frac{1}{2}[/tex]
What is a 30-60-90 triangle?The 30-60-90 triangle is called a special right triangle as the angles of this triangle are in a unique ratio of 1:2:3.
According to the given sum:
In theory, we know,
For a 30-60-90 triangle, the sides opposite to 30° is x , side opposite to 60° is x*[tex]\sqrt3}[/tex] and the side opposite to 90° is 2x
Therefore,
If x = 1,
The sides are [tex]\sqrt{3},2,1[/tex] where,
perpendicular = [tex]\sqrt{3}[/tex]
Base = 1
Hypotenuse = 2
We know sinФ = [tex]\frac{perpendicular}{Hypotenuse}[/tex]
But in the case of sin30 , we have to take perpendicular as 1 and hypotenuse as 2, that is the angle has to be at base. If it was sin60, we would have taken perpendicular as [tex]\sqrt{3}[/tex] and hypotenuse as 2.
Therefore,
Sin30 = [tex]\frac{1}{2}[/tex]
Hence, we can conclude that the value of sin30 is [tex]\frac{1}{2}[/tex].

Sharyce put some money in a savings account that paid 2.7% simple interest. After a year, the account was worth $7,890.44. What was the amount Sharyce originally deposited?
Step-by-step explanation:
P=A/(1+rt)
P = 7890.44 / ( 1 + (0.027 × 1)) = 7682.9990262902
P = $7,683.00
Sharyce originally deposited $7,683 into the savings account.
What is the formula for simple interest?The formula for simple interest is as follows:
I = Prt
Where I is the interest earned, P is the principal (the amount originally deposited), r is the interest rate (as a decimal), and t is the time (in years).
We know that after a year, the account was worth $7,890.44, so the interest earned is:
I = $7,890.44 - P
We also know that the interest rate is 2.7% or 0.027 (as a decimal), and the time is 1 year.
Substitute these values into the formula and solve for P:
I = Prt
$7,890.44 - P = P x 0.027 x 1
$7,890.44 - P = 0.027P
$7,890.44 = 1.027P
P ≈ $7,683
Therefore, Sharyce originally deposited $7,683 into the savings account.

It adds up to a right angle and it will be 90°
Answer:
Complementary
Step-by-step explanation:
Complementary angles sum to 90°
(6x + 1)° and 29° form a right angle , that is
(6x + 1) + 29 = 90°
Since the angles sum to 90° they are complementary
write an equation for a sine function and for a cosine function.
sine:
vertical shift - 3
horizontal shift - 0

cosine:
vertical shift - -3
horizontal shift - 4
amplitude - 2
period - 2pi

Answer: 1/2
Step-by-step explanation:
f(x) = A sin (Bx - C) + D
amplitude = |A|
period =
phase shift =
vertical shift = D
A
amplitude of 3 is given so 3 = |A| → A = ± 3, since it is stated that this is a positive function, then A = 3
B
period of 6π is given so

okay so angle O is connected to arc GU. to find angle O you musit find Arc GU
if Arc GO is 48 degrees and arc OU is 107 degrees, then you add those together.
107 +48=155
a circle has a total of 360 degrees
so 360-155= 205
205 is arc GU
205 divided by 2 will give you angle O
O is 102.5 degrees
