Answer:
(a) a ≈ 22.7 meters, (b) c ≈ 10.6 meters, (c) ∠A = 65°
Step-by-step explanation:
assuming side a/c is side BC/AB since it's opposite of angle A/C
(a) SOH CAH(cos = adjacent side/hypotenuse) TOA
=> cos (25°) = BC/AC or a/b
=> cos (25°) = a/25
=> a = cos (25°) × 25
=> a ≈ 22.7
(b) SOH(sin = opposite side/hypotenuse) CAH TOA
=> sin (25°) = AB/AC or c/b
=> sin (25°) = c/25
=> c = sin (25°) × 25
=> c ≈ 10.6
(c) 180° - 25° - 90°(the right angle) = 65°

Which expression shows the quotient of two terms where one of the terms includes the coefficient of 8?
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete; So, I will solve generally
Required
Quotient of two terms where 1 has a coefficient of 8
The quotient (Q) of a and b can be represented as:
[tex]Q = \frac{a}{b}[/tex]
Where a and b are the terms
For a or b to have a coefficient of 8, then a or b must be
[tex]a\ or\ b = 8x[/tex]
Where x is the variable
So, the quotient can be expressed as any of:
[tex]Q = \frac{8x}{y}[/tex]
[tex]Q = \frac{z}{8i}[/tex]
[tex]Q = \frac{24b}{8c}[/tex]
As long as one of the terms has a coefficient of 8

2x + 2y = –2 and 3x – 2y = 12 what does x and y equal?
Answers
Answer:
(2,-3)
Step-by-step explanation:
by elemination
2x + 2y = –2
3x – 2y = 12
cross out the 2y and -2y because the cancle each other.
that leaves 2x= -2
and 3x = 12.
simply add/subtract. 2x+3x=5x
-2+12=10.
5x=10
x=2.
now for the y. we have x so all we have to do is plug.
take any equation. 2x + 2y = –2 and plug 2 into the x.
2(2)+ 2y = –2
4+2y= -2
-2-4= -6
2y=-6
y=-3.
put x and y into ordered pairs
(2,-3) and done.
easy peasy.
Answer:
x=2 y= -3
Step-by-step explanation:
2x+2y = -2
x+y = -1 (dividing both sides with 2
x+1 = -y
3x - 2y = 12
3x + (-y)(2) = 12
3x + (x+1)(2) = 12
3x+2x+2=12
5x+2=12
x=2
-y= 1+2
y= -3

solve the equation 243×=73, where × is the base of the number.
Answers
x= 73/243
x= 0.300412
The value of × that satisfies the equation 243× = 73 is approximately 0.6691.
To solve the equation 243× = 73, where × represents the base of the number, we need to determine the value of × that satisfies the equation.
We can start by rewriting the equation as an exponential equation:
243ˣ= 73
To solve for ×, we need to isolate × on one side of the equation. We can do this by taking the logarithm of both sides of the equation. Let's take the logarithm with base 10 (log) for simplicity:
log(243ˣ) = log(73)
Applying the logarithmic property, we can bring down the exponent × as a multiplier:
× * log(243) = log(73)
Now, we can solve for × by dividing both sides of the equation by log(243):
× = log(73) / log(243)
× ≈ 0.6691
Therefore, the value of × that satisfies the equation 243× = 73 is approximately 0.6691.

.01*.5ˣ
Step-by-step explanation:
we can see that x=0 y= .01
so in our equation
a*bˣ
a=.01
This is throuhg plugging in 0 for x
a*b⁰=.01
a*1=.01
a=.01
Now it's just a matter of finding b
to do this just plug in a value
we know that when x=1 y=.005
.01*b¹=.005
b= .5
So our final equation is : .01*.5ˣ

Step by Step explanation:
All u have to do to figure this out is to first count the total amount of letters and in this case there are 8. To find the probability of a specific letter, you have to count how many of that letter there is in the total of 8. For example the letter A's probability is 3/8 since there are 3 A's and 8 letters in total.
