What is always true about a line that slants downward from left to right?

Select all that apply.

A) The slope of the line is negative.

B) As the value of one variable increases, the value of the other variable decreases.

C) The slope of the line is a fraction.

D) The graph of the line has extremely small values.

Answer:

a. t = I/Pr

b. The value of t in the table is 3 years

Step-by-step explanation:

Solve for t in the formula.

I = Pr

~Divide pr to both sides

I/Pr = t

Using the formula above, we can solve for t.

75/(500)(0.05) = t

75/25 = t

3 = t

Best of Luck!

Step-by-step explanation:

There are 12 children tickets did the group buy.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The group bought 20 admission tickets for $340.

And, Adult tickets cost $20, and children’s tickets cost $15.

Let number of children = x

And, Number of adult = y

Hence, We get;

The system of equations are,

x + y = 20  

y = 20 - x .. (i)

And, 15x + 20y = 340

3x + 4y = 68 .. (ii)

Substitute the value of y from (i) in (ii);

3x + 4(20 - x) = 68

3x + 80 - 4x = 68

80 - 68 = x

x = 12

Thus, There are 12 children tickets did the group buy.

Answer:

I am not sure because this is just an expression but I have a feeling I know where your teacher is going with this.

Step-by-step explanation:

She is saying the variable B stands for 14 feet and the variable C is 20 feet.

The statements that are true are;

Function 2 has a greater rate of change than function 1.

Function 2 has a greater y-intercept than function 1.

Step-by-step explanation:

Given that function 1 has the table;

x  y

0 -2

2  0

3   1

5   3

Finding the slope of the linear function gives the rate of change of the function. In this case,

m=Δy/Δx

m=3-1/5-3 = 2/2 =1

The equation of the linear function is given as;

m=Δy/Δx

y-3/x-5= 1

y-3=x-5

y=x-5+3

y=x-2

y-intercept is -2

In function 2, the line passes through points (-2,0) and (0,4)

Finding the slope of the line,

m₁=Δy/Δx

m₁=4-0/0--2

m₁= 4/2 =2

Rate of change is 2

Finding the equation of the line

y-4/x-0 = 2

y-4=2(x-0)

y-4 =2x

y=2x+4

The y-intercept is 4

The statements that are true are;

Function 2 has a greater rate of change than function 1.

Function 2 has a greater y-intercept than function 1.

Answer: The drawing in the attached figure

Step-by-step explanation: we know that

An isosceles triangle, has two equal sides and two equal interior angles

In this problem, the floor of the entryway to an office building is in the shape of an isosceles triangle

step 1

Find the measure of the vertex angle

Remember that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

Let

x ---> the measure of the vertex angle of triangle

step 2

Find the length of the congruent sides of triangle

Applying the law of sines

Let

c ----> the length of one congruent side

we have

substitute

solve for b

step 2

Make a scale drawing of the entryway

The scale drawing is 1 cm : 2 cm

That means

1 cm in the drawing represent 2 cm in the actual

or

1 cm in the drawing represent 0.02 m in the actual

Find the dimensions in the drawing

For a=8 m

For b=5.22 m

step 3

Draw the triangle

Answer:

Step-by-step explanation:

Since this is a test, I'll give a hint.

This problem can be a little confusing, but thats ok! The problem is trying to make two models, (each model is a number) and asking you to find what the addition sentence is.

If that makes you confused, then that's probably the right response! The first thing you would need to know is what are they dividing the whole circles of? Thirds? Seconds? Sixths?

You would then need to know how many whole numbers are there. "Whole numbers" are basscially fully shaded circles.

Hope this helps!

Answer:

1152 ft^2

Step-by-step explanation:

There are 7 faces on this solid.

I will label the faces and will calculate each area with an explanation.

Faces 1 and 2:

The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.

Each face is a rectangle and a triangle.

area = area of rectangle + area of triangle

area = LW + bh/2

area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2

This is area of of face 1, the front face. Face 2, the rear face has the same area.

A1 = 126 ft^2

A2 = 126 ft^2

Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft

area = LW

area = 9 ft * 20 ft = 180 ft^2

A3 = 180 ft^2

Faces 4 and 5:

The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.

area = LW

area = 12 ft * 20 ft = 240 ft^2

A4 = 240 ft^2

A5 = 240 ft^2

Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.

area = LW

area = 6 ft * 20 ft = 120 ft^2

We need 2 of these area.

A6 = 120 ft^2

A7 = 120 ft^2

total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7

total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 +  120 ft^2 + 120 ft^2

total surface area = 1152 ft^2
