Answer: A=C+7
Step-by-step explanation:
Let’s say hypothetically C=6, then B would be 4 since you would have to subtract 2 and A would be 13 since 4+9=13
The difference between 13 and 6 is 7, but that would work with any number and i’m just using c=6 as an example to make the problem easier to understand
Answer: Arc CE measures 62 units
Step-by-step explanation: What we have in the question is a circle with two secants ABC and ADE. The two secants have been extended such that two arcs have been formed which are, major arc CE (that is, 4x - 10) and minor arc BD (that is 26).
When you have a circle with two intersecting secants, the angle x (that is angle CAE) is derived as half of the difference of the two intercepted arcs. That is;
Angle x = 1/2 [CE - BD)
Angle x = 1/2 [ (4x - 10) - 26]
Angle x = 1/2(4x - 36)
Cross multiply and we now have
2x = 4x - 36
Collect like terms and we now have
36 = 4x - 2x
36 = 2x
Divide both sides by 2
18 = x
Having calculated x as 18, where arc CE equals 4x - 10, then substitute for the value of x.
CE = 4(18) - 10
CE = 72 - 10
CE = 62
Answer:
Step-by-step explanation:
The speed of light is 
and its frequency is 
.
The speed of light is given as:
c = λ * f
where λ = wavelength of light
f = frequency of light
Therefore, the wavelength is given as:
λ = c / f
=> λ = 
=> λ =
The wavelength of the light is
Answer:
$1276.47
Step-by-step explanation:
Given that the designers rug is sold for $850.98 .
A 50% markup based on cost is added.
The new cost Will be 50% of $850.98 added to $850.98.
That’s 50%/100% x $850.98
0.5 x $850.98
$425.49
New cost = $850.98 + $425.49
= $1276.47
The cost of the designers rug will be $1276.47
