Answer:

Step-by-step explanation:

The equation for the area of a triangle is base length (12) multiplied by the height length (10.4) divided by 2. Two of the same triangle create a rectangle, and by multiplying the base and the height you find this rectangle. To find the are of the triangle, you just need to remove the other triangle (divide by 2).

A=b*h/2

Answer:

t=v/dl

Step-by-step explanation:

v=dlt you want the t to be by itself on one side

t=v/dl so divide the other side by d and l

D. Add 3 positive and add 3 negative

B. -6

Step-by-step explanation:

The inverse of y=2/3x-5 is  3/2x + 15/2

An inverse is a function that serves to “undo” another function.

Given a function, y = 2/3x -5

Exchange x and y

x = 2/3y -5

Solve for y

Add 5 to each side

x+5 = 2/3y-5+5

x+5 = 2/3y

Multiply each side by 3/2

3/2(x+5) = 3/2*2/3y

3/2x + 15/2 =y

Hence, The inverse is 3/2x + 15/2

Answer:

-28

Step-by-step explanation:

The big thing to remember here is

Slope=Rise/Run

We can put x for the run and get this equation

21/x=-3/4

From here it gets really easy. To find the value of x we can change -3/4 into 21/-28 because in this case we need a common numerator. 21/x=21/-28 and it is obvious that x=-28

Hope this helped let me know if you have questions.

Maria : 18÷ 15= 1.2

Answer:

f⁻¹(x) = (x + 2)/3

Step-by-step explanation:

I'm going to assume the question is asking for the inverse. If that is the case, you want to switch x and y in the equation and solve for y.

f(x) = 3x - 2

x = 3f(x) - 2

x + 2 = 3f(x)

(x + 2)/3 = f⁻¹(x)

Therefore, the inverse is f⁻¹(x) = (x + 2)/3.

The percentage of numbers randomly generated by Taylor's computer that is less than 0.5 will be 12.5% .

A percentage is a minimum number or ratio that is measured by a fraction of 100.

A numerical distribution with continuous results is a density curve. A density curve is, in other terms, the graph of a continuous distribution. Which implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete).

Also the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).

The percentage of numbers randomly generated by Taylor's computer are less than 0.5 is;

P(0≤X≤0.5)

= 1/4 (0.5 - 0)

= 1/4 (0.5)

= 0.125

That is 12.5%

Hence, The percentage of numbers randomly generated by Taylor's computer that is less than 0.5 will be 12.5% .

Step-by-step explanation:

after 4 hours, the water level decreased by 8 feet

which is -8

Therefore -8/4 = -2 change in water level every hour

Answer:

The constant rate of change is 2 feet every hour.

Step-by-step explanation:

Since the level of the water was at 10 feet at 2 pm, and the water at 6 pm was at 2 feet, the water level dropped 8 feet in 4 hours.

With this information we can create the ratio 4:8 and when you simplify the ratio down to 1, you get 1:2

1 Representing 1 hour

2 Representing 2 feet

Every hour, the water level drops 2 feet.
