Answer:

$=75$ $ft^{2}$

Step-by-step explanation:

Area is found by mulitplying width and height.

$A=7.5(5)\\$

$A=37.5\\$ in

The ratio is 0.5in : 1ft, so if you multiply that ratio to the answer, you should get the answer in feet.

$37.5$ in x $\frac{1ft}{0.5in}$ $=75$ $ft^{2}$

A truck left a station at 6:00am traveling at a rate of 45km/h. A van left the same place 2 hours later heading in the same dire

OverLord2011 [107]

The Van would catch up with the truck at 6:00 pm

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

Let us say the van catch up with the truck after t hours at a distance d.

For the truck:

45 = d/t

d = 45t

For the Van:

54 = d / (t - 2)

d = 54t - 108

45t = 54t - 108

9t = 108

t = 12 hours

The Van would catch up with the truck at 6:00 pm

Based on a kc value of 0.210 and the data table given, what are the equilibrium concentrations of xy, x, and y, respectively?

Geometry PLS HELP due soon

Answer:

(3) $x = 7.5$ and $y = 51$

(4) $x = 6$

Step-by-step explanation:

Question 3

Required

Solve for x and y

We have:

$16x - 18 + 10x +3 = 180$ --- angle on a straight line

Collect like terms

$16x + 10x = 180 + 18 - 3$

$26x = 195$

Solve for x

$x = 195/26$

$x = 7.5$

Also:

$16x - 18 = 2y$ ---- opposite angles

So, we have:

$16 * 7.5 - 18 = 2y$

$120 - 18 = 2y$

$102 = 2y$

Divide by 2

$51 = y$

$y = 51$

Question 4:

Required

Solve for x

We have:

$11x - 2 + 5x - 4 = 90$ ---- angle at right-angled

Collect like terms

$11x + 5x = 90 +2 + 4$

$16x = 96$

Divide by 16

$x = 6$

Michelle plans on raising $80 for her softball team. To raise the money, she is selling team shirts for $10 each.

8_murik_8 [283]

Given:

Michelle plans on raising $80.

Selling price of each shirt = $10

So far she has raised $20.

To find:

The number of more shirts she needs to sell.

Solution:

Let x be the number of more shirts she needs to sell.

Selling price of one shirt = $10

Selling price of x shirt = $10x

Total raising amount = $(10x + 20)

Michelle plans on raising $80. So,

$10x+20=80$

Subtract both sides by 20.

$10x=80-20$

$10x=60$

Divide both sides by 10.

$x=\dfrac{60}{10}$

$x=6$

So, the required equation is $10x+20=80$

Therefore, the correct option is A.
