The name of the ray shown would be: C. ray AG.
What is a Ray?A ray can be defined as a part of a line which has a fixed starting point that is called an endpoint and extends to infinity towards the opposite direction of the fixed point, called the endpoint.
How to name a Ray?The first letter to use when naming a ray is the letter of the endpoint, which is the starting point of the ray, then use another letter that the ray passes through to infinity. There would be only one arrow head facing the right, drawn on top of the letters used in naming the ray.
The image shows an endpoint of A, which marks the starting point. The line extends from G to infinity as well.
Therefore, the name of the ray shown would be: C. ray AG.

Answers
Answer:
150
Step-by-step explanation:
The question is unclear. Do they want an angle that is under 180 (to your left) or over 180 (to your right)? I'm guessing that it is just under 180.
Each hour on a clock takes up 30 degrees. Each 5 minutes hand sweep out out 5/60 * 360 = 30 degrees as well. This angle looks like it is 5 minutes to seven if it was on a clock.
So the large angle from 12 oclock would sweep out 210 degrees and that would mean that the left angle would be 150. But the time is not quite 7 o,clock.
My guess would be 150. Remember, this is an estimate. You can't use a protractor on the question.
A bank offers an annual simple interest rate of 9% on home improvement
loans. Tobias borrowed $20,000 over a period of 4 years. How much did
he repay altogether?
Answers
Answer:
Tobias repayed a total of $7,200.
Step-by-step explanation:
If Tobias borrowed $20,000, and the annual interest rate is 9% of this per year, then we need to find 9% of 20,000.
20,000 x 0.09 = 1,800
Therefore, the yearly interest rate is $1,800. Now, we need to multiply this by 4.
1,800 x 4 = 7,200
Therefore, Tobias repayed a total of $7,200.
Hope this helps! :D

Answers
Probability that [tex]x^2+y^2+z^2\leq 1[/tex] is 0.523
Given that a point (x, y, z) is in space which is randomly selected as
[tex]-1\le x \le 1$,$-1\le y \le 1$,$-1\le z \le 1$[/tex]
These three equations represents a cube in space.
Length of each side of the cube = 1 - -1 = 2
Now [tex]x^2+y^2+z^2\leq 1[/tex] represents a sphere with center (0, 0, 0) and of radius less than or equal to 1.
So we can imagine that this sphere is inside the cube.
So the probability that [tex]x^2+y^2+z^2\leq 1[/tex] = Volume of the sphere/Volume of the cube
Volume of sphere with radius 1 = [tex]\frac{4}{3} \pi r^3=\frac{4}{3} \pi \times 1 = \frac{4}{3}\times 3.14 = 4.186[/tex] cubic unit
Volume of the cube of length 2 = [tex]2^3 = 8[/tex] cubic units
So the probability that [tex]x^2+y^2+z^2\leq 1[/tex] = 4.186/8 = 0.523

Answers
The value of the logarithmic expression log(10³ x) is 3 + log(x).
The opposite of exponential functions is logarithmic functions. The exponential function y = aˣ has the inverse, [tex]x=a^{y}[/tex]. The exponential equation [tex]x=a^{y}[/tex] is defined as being identical to the logarithmic function y = logₐ x.
The properties of logarithm are:
Product rule: logₐ (mn) = logₐ m + logₐ n
Quotient rule: logₐ (m/n) = logₐ m – logₐ n
Power rule: logₐ (mn) = n( logₐ m )
Consider the logarithmic expression,
a = log ( 10³ x )
Using the property of logarithm:
logₐ ( mn ) = logₐ m + logₐ n
Then,
a = log( 10³ x )
a = log( 10³ × x)
a = log( 10³ ) + log( x )
By using the property of logarithm:
logₐ mⁿ = n( logₐ m )
So,
a = 3( log 10 ) + log( x )
a = 3 + log ( x )
Therefore, log( 10³ x ) = 3 + log ( x ).

Answers
Answer
The slope-intercept form of the equation of the line with a slope of 1/4 and y-intercept at the origin:
[tex]y=\frac{1}{4}x[/tex]
Step-by-step explanation:
Given
The slope = m = 1/4The y-intercept is (0, 0)We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
substituting the values m=1/4 and the y-intercept b=0 to determine the equation in slope-intercept form
[tex]y=mx+b[/tex]
[tex]y=\frac{1}{4}x+0[/tex]
[tex]y=\frac{1}{4}x[/tex]
Thus, the slope-intercept form of the equation of the line with a slope of 1/4 and y-intercept at the origin:

Step-by-step explanation:
Andre wants to purchase some onions and tomatoes to make tomato soup. The recipe states that four times the number of tomatoes, , plus five times the number of onions, x, should produce 56 bowls of tomato soup. A different recipe states that two times the number of tomatoes used minus the number of onions used should produce 21 bowls of tomato soup. What is the resulting recipe for the number or tomatoes and onions used in the soup when Andre adds the two recipes together?
Let
Tomatoes = x
Onions = y
Recipe 1:
4x + 5y = 56
Recipe 2:
2x - y = 21
4x + 5y = 56 (1)
2x - y = 21 (2)
Multiply (2) by 5
4x + 5y = 56 (1)
10x - 5y = 105 (3)
Add
10x + 4x = 105 + 56
14x = 161
x = 161 / 14
= 11.5
Substitute x =11.5 into
2x - y = 21
2(11.5) - y = 21
23 - y = 21
-y = 21 - 23
-y = -2
y = 2
Tomatoes = 11.5
