what is the measurement of
Answer: Angle A = 120° and angle C = 45°
Step-by-step explanation: The first thing to note at the back of our minds is that the sum of the interior angles of a triangle equals 180°. Given that the three angle are available, we can start by adding them all together. Hence,
{12x + 12} + 15 + {3x + 18} = 180
12x + 12 + 15 + 3x + 18 = 180
By collecting like terms, we arrive at,
12x + 3x + 12 + 15 + 18 = 180
15x + 45 = 180
Subtract 45 from both sides of the equation
15x = 135
Divide both sides of the equation by 15
x = 9
At this point, we can now substitute for the value of x = 9 in the expressions representing angles A and C.
Angle A = 12x + 12
= 12(9) + 12
= 108 + 12
= 120
Angle A = 120°
Angle C = 3x + 18
= 3(9) + 18
= 27 + 18
= 45
Angle C = 45°
How to solve systems using elimination
See explanations below on solving simultaneous equations by elimination.
Step-by-step explanation:
In solving simultaneous equations by elimination, you make one side of the variables equal and eliminate that side by either addition or subtraction, then solve the remaining variable whose value is then used in one of the equations to find the other variable. For example;
(i) 4x - 2y= 10
(ii) x+ y =4
Making the x variable part equal to eliminate x
1(4x-2y=10)--------multiply by 1
4(x+y=4) ---------multiply by 4
4x -2y =10
4x+4y=16
Apply subtraction to eliminate the x variables
0 +6y =6
6y=6
y=6/6 = 1
Use the value of y =1 in the equation x+y= 4
x+y=4
x+1=4
x=4-1 = 3
x= 3, and y=1

Rewrite the following in the form log(c).
log(6) – log(2)
Answer:
Step-by-step explanation:
㏒(6)-㏒(2)=㏒(6/2)=㏒ 3
The expression log(6) – log(2) in form of log(c) is log(12).
What is Logarithm?Logarithms are another way of writing exponents in mathematics. A number's logarithm with a base equals another number. Exponentiation is the inverse function of logarithm.
A logarithm is defined as the number of powers to which a number must be increased in order to obtain some other numbers. It is the simplest way to express enormous numbers.
We have to write the expression log(6) – log(2) in form of log(c).
Using product property for logarithms
log a + log b= log (ab)
Here, a= 6 and b= 2 then
ab = 6 . 2= 12
Thus, the required form of log(6) – log(2) is log(12).

A 500-kilogram horse runs at 5 meters/second. The horse’s kinetic energy is (blank)joulese g = 9.8 N/kg.)
Answer:
KE = 6250 Joule.
Step-by-step explanation:
Every moving body has kinetic energy and it is given by the expression
[tex]KE = \frac{1}{2}mv^{2}[/tex]
where the moving body has m as the mass and v as the velocity.
If m is in Kg and v is in meter/sec, then KE will be expressed in Joule.
Now, in this case, m = 500 and v = 5 meter/sec.
So, [tex]KE = \frac{1}{2} \times 500 \times (5)^{2} = 6250[/tex] Joule. (Answer)
An object is launched from a platform.
Its height (in meters), x seconds after the launch, is modeled by:
h(x)=-5x2verb +20x+60
What is the height of the object at the time of launch?
Answer:
60 feet
Step-by-step explanation:
The height, h (in meters), of the object launched from a platform is represented by the equation
[tex]h=h(x)=-5x^2+20x+60[/tex]
where x is the time (in seconds) passed after the launch.
The time of launch is [tex]x=0[/tex] (0 seconds passed after the launch)
Substitute [tex]x=0[/tex] to find the height:
[tex]h=h(0)=-5\cdot 0^2+20\cdot 0+60=60\ feet[/tex]

Answer:
Step-by-step explanation:
50
The ratio of the whole numbers in its lowest term is ratio $2 to $3 i.e. [tex]\mathbf{\dfrac{2}{3}}[/tex]
A ratio of two integers a and b can be represented into a fraction as numerators and denominators.
[tex]\mathbf{\dfrac{a \to numerator}{b \to denominator}}[/tex]
To recognize and determine the ratio of the whole numbers in their lowest terms, we will multiply both the numerator and the denominator by 10.
i.e.
[tex]\mathbf{=\dfrac{1.00}{1.50}}[/tex]
[tex]\mathbf{=\dfrac{1.00\times 10}{1.50 \times 10}}[/tex]
[tex]\mathbf{=\dfrac{10}{15}}[/tex]
DIvide both the numerator and denominator by 5;
[tex]\mathbf{=\dfrac{2}{3}}[/tex]
Therefore, we can conclude that the ratio of the whole numbers in its lowest term is ratio $2 to $3 i.e. [tex]\mathbf{\dfrac{2}{3}}[/tex]

Skyler is 104 miles away from Marcus. They are traveling towards each other. If Marcus travels 8 mph faster than skyler and they meet after 4 hours, how fast was each traveling?
Speed of skyler is 204 mph and speed of marcus is 212 mph
Solution:
Skyler is 104 miles away from Marcus
Therefore,
Distance = 104 miles
They meet after 4 hours
Time taken = 4 hours
Let "x" be the speed of sklyer
Marcus travels 8 mph faster than skyler
Therefore,
Speed of marcus = 8 + x
They are traveling towards each other
Since they are traveling towards each other, we can add up their speeds
Speed = x + 8 + x = 2x + 8
The distance is given by formula:
[tex]distance = \frac{speed}{time\ taken}\\\\104 = \frac{8+2x}{4}\\\\104 \times 4 = 8 + 2x\\\\8 + 2x = 416\\\\2x = 416-8\\\\2x = 408\\\\x = 204[/tex]
Thus speed of skyler = x = 204 mph
Speed of marcus = 8 + x = 8 + 204 = 212 mph
Thus speed of skyler is 204 mph and speed of marcus is 212 mph
There are two functions that can be used to describe the percent of people 25 years and older who have completed at least high school. For both functions f(x)=0.44x + 87.5 and g(x)=0.008x^2 + 0.42x + 87.5 is the number of years since 2008, and any y (or f(x) or g(x)) is the percent of people 25 and older completing at least high school. Assume that the trend of g(x) continues. Find g(15) and describe in words what this means.
g(15)=
Answer:
[tex]g(15)=93.8\%[/tex]
see the explanation
Step-by-step explanation:
Let
x ----> the number of years since 2008,
g(x) ----> the percent of people 25 years and older who have completed at least high school
we know that
[tex]g(x)=0.008x^2+0.42x+87.5[/tex]
so
For x=15 years since 2008
substitute
[tex]g(15)=0.008(15)^2+0.42(15)+87.5=93.8\%[/tex]
That means
In the year 2023 (2008+15) the percent of people 25 and older completing at least high school will be 93.8%
Final answer:
To find g(15), we substitute x with 15 in the function g(x) = [tex]0.008x^2 + 0.42x + 87.5[/tex], yielding g(15) = 95.6%. This means that in 2023, it's projected that 95.6% of people 25 and older will have completed high school according to the given quadratic trend.
Explanation:
The student is asking for the evaluation of the function g(x) = [tex]0.008x^2[/tex] + 0.42x + 87.5 at x = 15, which represents the number of years since 2008. To find g(15), we need to substitute x with 15 in the given function:
g(15) = 0.008(15)2 + 0.42(15) + 87.5
Calculating the value step by step:
152 = 225
0.008 × 225 = 1.8
0.42 × 15 = 6.3
1.8 + 6.3 + 87.5 = 95.6
Therefore, g(15) = 95.6.
In words, this means that if the trend described by function g(x) continues, then in the year 2023 (15 years after 2008), 95.6% of people aged 25 and older will have completed at least a high school education. This is a projection of graduation rates over time.

The Outstanding O's cereal box has been redesigned with the new size and shape
The new dimensions are,
L=20 cm
W=8 cm
H=30 cm
To get the required material, the surface area of the box with new dimensions is to be calculated.
So,
S.A=2(LW + WH + LH)

F is directly proportional to a.
If F = 24 when a = 8 find,
a when F = 18
Answer:
K = 3
a = 6
Step-by-step explanation:
F is directly proportional to a
That’s F = Ka
K is the constant
Divide both sides by a to get the constant k
K = F/a
When F = 24 and a =8
K = 24/8
= 3
When F = 18
a = ?
F = Ka
18 = 3 x a
18 = 3 x a
Divide both sides by 3
18/3 = 3 x a /3
6 = a

of a pizza. How much pizza
did they eat altogether?
Answer:
They ate 7/8 of a pizza altogether.
Step-by-step explanation:
So, you know Mrs. Rivera ate 3/8 of a pizza and Ms. Carter ate 4/8 of a pizza.
You add 3/8 + 4/8 and you get 7/8.
The ate 7/8 of a pizza altogether.
The quantity of pizza that Mrs. Rivera and Ms. Carter ate altogether is equal to [tex]\frac{7}{8}[/tex]
Given the following data:
Fraction Rivera ate = [tex]\frac{3}{8}[/tex]Fraction Carter ate = [tex]\frac{4}{8}[/tex]To calculate how much (quantity) pizza they ate altogether:
A fraction can be defined as a numerical quantity that isn't a whole number.

To find the x- intercepts let f(x) = 0, that is
(x - 8)(x + 9) = 0
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x - 8 = 0 ⇒ x = 8
The x- intercepts are x = - 9 and x = 8
