Step-by-step explanation:

They are trying to be tricky  :DDD  but we got this.

they give you the outside angle at H, but  you know both of those two angle also add to 180

180= 131 +∠h

I'm noting that we're solving for the minor angle H of the triangle,  the inside angle

49° = ∠h

we also , know that  H and J are equal,  b/c it's got the red marks , telling us the angles are the same.

use that same strategy to solve,  

180 = 2*49 + p

180-98 = p

82 = p

Do you see where I get the equation from? ( 180 = 2*49 + p )  ?

Answer:

C. 3

Step-by-step explanation:

First, use the distributive property. Multiply 4x and 1 each by 2.

This gives us the equation 50 + 8x - 2 = 72.

Next, subtract 2 from 50 to get 48. Subtract 2 from 2 to cancel it out.

Then, we have 48 + 8x = 72.

Subtract 48 from both sides. This leaves 8x = 24.

Divide both sides by 8 to get x = 3.

The required number of phones and accessories sold are x = 12, y = 5,

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Let the number of phones sold be x and the number of accessories sold be y.
According to the question,
He sold a total of 27 phones and accessories,
x + y = 27 - - - - -(1)

And, made a total of $180 in commission,
10x + 4y = 180 - - - - -(2)

Graph both the equation,
From the graph, the solution of the system of equations is given as,
x = 12, y = 5,

Since, when two intersect each other, is the point of a solution of the system of equation.

Thus, the solutions gives the number of phones and accessories sold as x = 12, and y = 5.

Answer: D. 3/8

Step-by-step explanation:

The rate of change or slope is rise/run

We see that the y decreases by 9 and the x decreases by 24, so our slope is -9/-24 = 3/8 because negative and negative will be positive.

So the answer is D

Answer:

C. -3/8

Step-by-step explanation:

To find the rate of change is the same as finding the slope. To find the slope between two points you'd use the slope formula, which is y2-y1 over x2-x1.

You'd get -8-1 over -8-16. -8-1 is -9. -8-16 is -24 so you'd get -9/-24.

Because that isn't one of the answer choices you have to simplify it. To simplify it you would divide both numbers by the same number. A common number they both share is 3. So then you'd divide -9 by 3 and you'd divide -24 by 3. -9 divided by 3 is -3. -24 divided by 3 is -8 so you'd get -3/-8. Which should be C. -3/8. Because both numbers are negative the answer should have a negative sign so you'd cross b and d out. And a isn't right because the 8 is supposed to be in the denominator and not in the numerator.

1.5i^- 3j^ is the perpendicular vector to the vector 3.0i^+1.5j^

Whenever there is a 90 degree angle between two vectors, they are said to be perpendicular.  Two perpendicular vectors dot product is zero. and dot product is scaler product of 2 vectors.

Let  b = xi^+ yj^ be the perpendicular vector to a vector

and we know that 2 vectors are perpendicular if thier dot product is 0

so it implies that

b.a(dot product) =0

=> (3i^+1.5j^) . (xi^+yj^)=0

=> 3xi^.i^+ 3y i^.j^ +1.5xj^.i^+1.5yj^j^=0

=>3x+1.5y=0  ----(i)

becaus i^.j^=0 and j^.i^0

=> x= 1.5 and y=-3 satisfies equation (i).

The perimeter of the irregular shape would be 34 cm.

What is the perimeter of any shape?

In geometry, the perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape.

By using the definition of the perimeter we can compute,

Perimeter = 4 + 2 + 2 + 3 + 3 + 6 + 9 + 5

The values of P and a that will make f(x)=Pa^x to be an exponential growth function is; A P = 1²; a = 2

The general formula for exponential growth function is;

y = a(b)ˣ

When a is a positive value and 'b' is the base greater than 1,

In order to represent exponential growth, a must be a positive number larger than 1.  If a is a fraction less than 1, we are basically taking a percent (less than 100) of the number and this will make it smaller, which would the become a decay function.  If a is a negative, the values would alternate between positive and negative.

I got this equation because the initial height is the starting so that would be the y-int which comes after the slope, the slope is 32 because it says that the plant has grown that amount of centimeters each day, and each day should refer to the rate meaning slope. That would be the equation that you would use to find the plant's height after a given number of days,

For example..

y=32(5) + 14

I plugged in a 5 for x meaning 5 days. so you'd multiply 32 by 5 which is 160 and then you'd add 14 and you'd get 174. Meaning that after 5 days the plant has grown 174 cm...

The numbers x and y values are the integer x = 29,288 and y = 713.

What is a linear equation?

Ax+By=C represents a two-variable linear equation in its standard form.

A linear equation with one variable has the conventional form Ax + B = 0. x is a variable, A is a coefficient, and B is constant in this situation.

An equation is used to show the relationship between variables, and numbers.

Let's call the two numbers x and y, where x is the first number and y is the second number. We are given that x + y = 30,000 and that 0.07x + 0.1y = 2,400.

Using substitution, we can solve for one variable in terms of the other and then substitute this expression into the other equation.
From the first equation, we can solve for y: y = 30,000 - x
Substituting this expression into the second equation, we get:
0.07x + 0.1(30,000 - x) = 2,400
0.07x + 3,000 - 0.1x = 2,400
Combining like terms, we get:
-0.03x = -600
Dividing both sides by -0.03, we get:
x = 20,000
Substituting this value back into the first equation, we can solve for y:
y = 30,000 - x
y = 30,000 - 20,000
y = 10,000
Therefore, the two numbers are x = 20,000 and y = 10,000.
Alternatively, we could have used elimination to solve the system. We can do this by adding the two equations together:
x + y = 30,000
0.07x + 0.1y = 2,400
0.07x + 0.1y + x + y = 30,000 + 2,400
0.17x + 1.1y = 32,400
Dividing both sides by 0.17, we get:
x + 6.47y = 190,588
Multiplying both sides of the first equation by 6.47, we get:
6.47x + 6.47y = 194,490
Subtracting the second equation from the first, we get:
5.47y = 3,902
Dividing both sides by 5.47, we get:
y = 712.5
Substituting this value back into the first equation, we can solve for x:
x = 30,000 - y
x = 30,000 - 712.5
x = 29,287.5

Since x and y must be positive integers, we can round these values to the nearest integer to get x = 29,288 and y = 713. These values are very close to the actual solution, which is x = 20,000 and y = 10,000. This is because we introduced some error when we divided both sides of the equation 0.17x + 1.1y = 32,400 by 0.17.
Hence, the numbers x and y values are the integer x = 29,288 and y = 713.

The graph of g is the graph of f translated 3 units right. Option C is the answer

In geometry, a translation is a type of transformation that involves moving a geometric figure from one location to another without changing its size, shape, or orientation.

Remember, in the cartesian plane or graph, the movement in x-axis is either to the left (negative) or right (positive).

Since f(x) = 2x + 1, looking at g(x) = 2(x + 3) + 1, you will notice that 3 is added to the value x. This is a movement in the positive x-axis (right translation) and the translation is by 3 units.

And we need to find the the standard deviation of this sample proportion

Let us assume the expected population standard deviation to be 10, and employing t-distribution to estimate sample size, the study would require a sample size of: 44 to estimate a mean with 67% confidence and a precision of 1.5.

Carly will have to attend school for 8 weeks before she takes a total of 24 quizzes.

Step-by-step explanation:

To determine the number of weeks Carly will have to attend school before she takes a total of 24 quizzes, we need to first calculate the proportion of quizzes taken to weeks attended by dividing the number of quizzes taken by the number of weeks attended:

Proportion = Number of quizzes taken / Number of weeks attended

Proportion = 15 quizzes / 5 weeks

Proportion = 3 quizzes / week

Next, we can use this proportion to calculate the number of weeks Carly will have to attend school before she takes 24 quizzes by multiplying the number of quizzes Carly wants to take by the reciprocal of the proportion:

Number of weeks = Number of quizzes / Proportion

Number of weeks = 24 quizzes / 3 quizzes/week

Number of weeks = 8 weeks

Therefore, Carly will have to attend school for 8 weeks before she takes a total of 24 quizzes.
