Answer:

$20

Step-by-step explanation:

let the regular price of the mirror be 'x'

x*25/100=5

25x/100=5

cross multiply

25x=500

divide both sides by 25

x=$20

A golf ball is hit off a tee at the edge of a cliff. Its x and y coordinates as functions of time are given by x = 18.1t and y =
Kitty [74]

Answer:

The vector for the ball’s position is \vec{r} = (18.1t)\hat{i} + (4.20t - 4.90t^2)\hat{j} \:m

Step-by-step explanation:

The position vector for a particle moving in the <em>x-y</em> plane can be written

\vec{r} = x\hat{i} + y\hat{j}

where x, y, and \vec{r} change with time as the particle moves while the unit vectors \hat{i} and \hat{j} remain constant.

We know that the x and y coordinates as functions of time are given by x = 18.1t and y = 4.20t - 4.90t^2, where <em>x </em>and<em> y</em> are in meters and <em>t</em> is in seconds.

Therefore, the vector for the ball’s position is \vec{r} = (18.1t)\hat{i} + (4.20t - 4.90t^2)\hat{j} \:m

Plzzz help plzzz I need help on both of them
Paul [167]
The answer to the first problem is G.

Since there are 3 boys and 9 girls who are left-handed, that makes 12 people in total in sixth grade who are left-handed. The total number of sixth graders at the middle school is 150 since there are 90 girls and 60 boys in that grade. Divide 150 from 12 to get 0.08. You change it to percentage form by multiplying 0.08 by 100 to get 8%.

The answer for the second problem is C. You change the percentage (in this case it is 76%) to decimal form by dividing by 100 to get 0.76. You then multiply 0.76 with 8,950 to get 6,802.

How to solve this problem pleas help
Jlenok [28]
The interior angles of a polygon add to 180°

3x - 11 + x - 8 + 2x + 7 + x + x + 8 = 180
8x - 4 = 180
8x = 184
x = 23
