Answer:

Tuesday

Step-by-step explanation:

Let the days of the week be numbered 1–7, starting with Monday and ending with Sunday. Let <em>t</em> represent today. We can equate the number of skirts finished by Friday (day 5) with the ones finished by Sunday (day 7) at the lower rate. (days × (skirts/day) = skirts)

... (5-t)×5 = (7-t)×3

... 25 -5t = 21 -3t . . . . . eliminate parentheses

... 4 = 2t . . . . . . . . . . . . add 5t-21

... 2 = t . . . . . . . . . . . . . divide by 2

Day 2 corresponds to Tuesday.

_____

<em>Check solution</em>

(5-2)·5 = 15 = (7-2)·3 skirts are being made.

Drag each value to the correct location on the equation. Each value can be used more than once, but not all values will be used.
MArishka [77]

Answer:

-303.11 -175

Step-by-step explanation:

The jet has a speed of magnitude 350 miles/hour and travelling in a direction of 210°. Hence the jet can be represented with |r| = 350, θ = 210°.

The component form of the vector has both the x component (horizontal component) and the y component (vertical component) Therefore:

The horizontal component = r_x=|r|cos\theta=350*cos(210^o)= -303.11

The vertical component = r_y=|r|sin\theta=350*sin(210^o)= -175

Valentin [98]
The bus drops Nigel off 64 miles away from the school.

Step by step Explanation:

An equation for this would be 312-14-234 (this was the equation I used. Since you would do left to write to solve the equation, you would do, 312-14 which equals 298. Then, the equation is left as 298-234, and when you solve that part to the equation, yoh would be getting 64. And that's how you would get the answer 64miles away from the school.
