The distance between R and S on the coordinate grid is ___ units. (Input whole numbers only.)

Answers

Answer:

The answer is 40.

Step-by-step explanation:

First you find the coordinates of both r and s. The coordinates are R coordinates. (-20 1/2 , 5) S coordinates (20,5). Since we have that written down next we have to add both -20 and 20. Before adding them you have to switch -20 to positive 20. Now you have 20 + 20. giving you 40. Since it says to put the whole number you put 40.

Which of the following is not another way of expressing 88 out of 100?

A) 22/25
B) 0.088
C) 88%
D) 0.88

Answers

The fraction 88/100 is equal to 88÷100 and can also be expressed as a decimal as 0.88 and expressed as a percentage as 88%.

Find the area of the hexagon

Answers

Answer:

The area is 78 square inches

Step-by-step explanation:

so you can split the hexagon into two trapezoids, and then find the area of one of those trapezoids, which is what I did. The area of a trapezoid I think is

a, b=base, h=height

A=a+b/2*h

is a really bad way of saying it, but that's how I know to do it.

So anyways I just substituted the numbers with their corresponding letters and solved. So the area of one trapezoid was 39, and since we have two 39's, you do 39*2 and you get 78.

Hope I helped

78 square inches I’m pretty sure

A fish is swimming at a constant rate toward the ocean floor. The equation
y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.
Which statement best describes the depth of the fish, given this equation?

A.From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.

B.From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.

C.From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

D.From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.

Answers

Answer:

explanation: if the fish is swimming towards the ocean floor it's descending 7 meter per second because -7x is the constant and 3 is the y-intercept or where the fish started

What is exponential growth factor?

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is and exponential growth equation

where x marks the temperature and y marks the number of people on the bench

From the graph , we can see that

As the temperature increases , the number of people at the bench increases

Hence , the exponential equation is solved

Answers

an isosceles triangle is when 2 angles are the same measure. an triangles angle equal to 180 degrees. therefore angle A is 80 degrees as well as angle B equals 80 degrees. since the angles of a triangle equal to 180 you subtract the two known angles to find angle C. So 180-80-80 which equals to 20.

Therefore angle C=20 degrees
