Answer:

Step-by-step explanation:

Answer is C because if swimmer A does 14 laps to start an 3 laps every day after that and on the chart swimmer B does 11 laps to start and 2 laps every day after that you would compare.

on day 3 swimmer B has 17 (shown on chart)

on day 3 swimmer A has 23 (14, 17, 20, 23)

if you would want it to complicate it 14:3 and 11:2

14 ÷ 14 is 1

3 ÷ 14 is .214

11 ÷ 11 is 1

2 ÷ 11 is .181

Sophie is training for a triathlon by running, biking, and swimming. last week, she ran, biked, and swam 104 miles altogether. s

72 miles Sophie bike last week. we get the answer by making and solving equation.

Let's take x miles, Sophie swam

from the question we get,

she runs ⇒3 × x = 3x miles

she biked ⇒ 3 × 3x = 9x miles

Then by solving, ⇒3x + 9x + x = 104

⇒ 13x = 104

⇒ x = 8

therefore, we get

9x = 9 × 8

= 72 miles

lastly, we get that she biked 72 miles last week.

There are two types of equations: identities and constraints. The ID applies to all values of the variable. Constraint expressions apply only to specific values of variables. Equations are written as two expressions joined by an equal sign.

There are three main forms of linear equations. Point-slope format, standard format, and slope-intercept format.

A person is strolling along a moving walkway at a constant velocity of +1.00 m/s with respect to the walkway, which moves at a c

Bezzdna [24]

Refer to the diagram shown below.

The velocity of the person on the walkway relative to the ground is the velocity of the walkway (relative to the ground) plus the velocity of the person relative to the walkway.
It is
1.0 + 0.5 = 1.5 m/s

The person on the ground moves at - 0.2 m/s, which is in the opposite direction to that of the walkway and the person on the walkway.
Therefore the velocity of the person on the walkway relative to the person on the ground is
105 - (-0.2) = 1.7 m/s

Answer: 1.7 m/s
