Which answer correct estimates the product of 3.09 × 304.87

miv72 [106K]

The answer is 942.05. You get it by multiplying the two numbers together which should give you the product of 942.0483, since the 0 is not the number 5 or more ( which is the rule to round to a higher number) then you go to the hundredths place value which will be underlined for you... 942.0<u>4</u>83 and look to the right and since 8 is higher than 5, you change the four to a five, thus giving you your answer 942.05

Selena was comparing the flying speeds of different birds in science class. Which of the three birds flies fastest? Why?

Mashcka [7]

Answer:

Option C. The robin flies fastest because its rate is 15 m/s

Step-by-step explanation:

Let

x -----> the time in seconds

y ----> the distance in meters

The speed is equal to divide the distance by the time

In this problem, the slope or unit rate of the linear equation is the same that the speed

<em>Robin's Flight</em>

<em>Find the slope</em>

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take two points from the table

(2,30) and (3,45)

substitute in the formula

$m=\frac{45-30}{3-2}$

$m=\frac{15}{1}$

$m=15\frac{m}{sec}$

<em>Cardinal's Flight</em>

$y=10x$

$m=10\frac{m}{sec}$

<em>Blue Jay's Flight</em>

take two points from the graph

(0,0) and (2,20)

substitute in the formula

$m=\frac{20-0}{2-0}$

$m=\frac{20}{2}$

$m=10\frac{m}{sec}$

Compare

The robin flies fastest because its rate is 15 m/s

The image below shows two parallel lines cut by a transversal. What is the value of x?

Nina [5.8K]

Since the two lines are parallel and it is cut by a transversal,
75+X+5=180
=>80+X=180
=>X=180-80
==>X=100
Hope this helps u...!!!!!

PLEASE HELP ME. I know I ask a lot, but I don’t know what I should come up with

Artemon [7]

Answer:

equation :

1. b + 5 = 3

2. 3b = - 6

3. 10b = -20

1. b = 3 - 5 = - 2

2. 3b/3 = - 6/3 = - 2

3. 10b / 10 = - 20 / 10 = - 2
