The best estimate would be A)1.0 Here's why: If they all ate 0.32 of a pizza pie, you would do 0.32 x 3, which equals 0.92, to find out how much they ate altogether. 0.92 is closer to 1.0 than it is to 0.5 or 0.25

At a graduation ceremony, names were read at the rate of five names per minute. If the names had been read at the rate of seven
Alex Ar [27]

Answer:

<u>420 names were read</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Rate of names read per minute at the graduation ceremony = 5

2. If the names had been read at the rate of seven names per minute, the ceremony would have taken 24 minutes less. How many names were read?

x = Number of minutes it takes to read the names at the rate of seven names per minute

x + 24 = Number of minutes it takes to read the names at the rate of five names per minute

Solving for x:

5 * (x + 24) = 7x

5x + 120 = 7x

5x - 7x = -120 (Subtracting 120 and 7x at both sides)

-2x = -120

x = -120/-2

x = 60 ⇒ 7x = 420

<u>420 names were read</u>

Which equation satisfies all three pairs of a and b values listed in the table?
Tom [10]

Answer:

y = 3x -10

Step-by-step explanation:

The function seems to increase at a constant rate of 3 units. This means that the equation that satisfies these points could be that of a straight line.

We use the first two points to find the slope of the line.

(0, -10)

(1, -7)

(2, -4)

The equation of a line is:

y = mx + b

Where m is the slope of the line and b is the cutoff point with the y axis.

To find the slope of a line we use the following equation:

m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-7 - (- 10)}{1-0}

m = 3

So:

y = 3x + b

The cut point (b) is found by replacing in the previous equation, any of the three points provided and clearing b.

-7 = 3(1) + b

b = -10

Now we can write the equation of the line sought.

y = 3x -10

You can verify that the three points provided belong to this equation.
