Answer:
1. D
2. x=65
Step-by-step explanation:
Hi!
Your answer is D because 78 is 120% of x
120% in decimal point is 1.2.
So it's 1.2x is the same as 120% of x
For question 8:
1.2x=78
Isolate x by divide 1.2 on both sides
78/1.2=65

Answers
Answer:
c = -4 d = 6
Step-by-step explanation:
8 - 2d = c 4c + 3d = 2
4(8 - 2d) + 3d = 2
32 - 8d + 3d = 2
32 - 5d = 2

the rate of growth is 34%
B
there were 1125 cell phone users in 2000.
С
the rate of decay is 3.4%
D
In the year 2005, there were more than 1350 cell phone users.
Answers
Answer: B
there were 1125 cell phone users in 2000.
Step-by-step explanation:
The initial number of cell phone users is the front coefficient that is then multiplied by the growth factor.
So the initial number of cell phone users in 2000 was 1125.
Raul came home with $3.00 in his pocket. He had given Rene $1.50 on his way home. Pedro gave him $1.00 that he had borrowed last week. How much money did Raul have at the beginning of the day?
Answers
Answer: $3.50
Step-by-step explanation:
He came home with $3.00.
He gave Rene $1.50 which means that $1.50 was deducted from his money.
Pedro gave him $1.00 which added to his money.
Money he had therefore was:
= 3 + 1.50 - 1
= $3.50

What is the minimum value for the function shown in the graph?
Answers
Answer:
2.5
The lowest point on the graph, or the minimum is at f(x)= 2.5
The minimum value of the given periodic function is, 2.5
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
A periodic function,
Period = 3π
The value of the function is in the range of (2.5, 4.5)
So,
Maximum value = 4.5
Minimum value = 2.5
Thus, the minimum value is 2.5

Answer:
$25,689.775
Step-by-step explanation:
The interest has to be in decimal form. So 1.25/100=0.0125
Plug everything into the equation for compound equation [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex]
Which is A = 24750 [(1 + 0.0125/1)^(1)(3)]
Type them in a calculator and get A ≈ $25,689.775
***the question says "compounded annually" so the equation for compound interest [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex] should be used. Your provided formula of A = P(1 + R times T) shouldn't be used here, it is for simple interest but not compound.*** (^_^)

The Height of triangular face is 692.820 feet,
The height of Pyramid is 800 feet.
What is pyramid?A pyramid is a three-dimensional polyhedron with three or more faces that are triangle-shaped and meet above the base. Faces are the triangular sides, and the apex is the point above the base. A pyramid is made by interfacing the base to the peak. To differentiate them from the base, the triangular sides are sometimes referred to as lateral faces. Each edge of the base of a pyramid connects to the apex that makes up the triangular face.
Given to Draw a Pyramid, with square base
and triangular faces are Equilateral,
length of Square base = 800 feet
The Drawing of pyramid is attached,
which shows h = height of pyramid
S = height of Triangular face
And base = 800 feet
2: To find height of Triangular face
since triangular face are Equilateral
side of triangle = base of pyramid = 800 feet
and height of Equilateral triangle = √3/2 × a
where a is side of triangle
S = √3/2 × a = √3/2 × 800
S = 692.820 feet
3: As we have height of triangle so we can calculate the height of pyramid by relation between height of triangle and height of pyramid
h² = S² + (x/2)²
where x is the length of side of base,
x/2 = 800/2 = 400
substitute values of S and x/2
h² = (400√3)² + (400)²
h² = 480000 + 160000
h² = 640000
h = 800 feet
Hence, the height of triangular face is 692.820 feet,
and the height of Pyramid is 800 feet.
