im new can anyone help

Answers

Answer:

We have the equation:

[tex]W = W_0*(\frac{1}{2})^{0.36*t}[/tex]

Where:

W₀ is the initial area of the wound, and t is the time in days.

Now, if we initially have a wound of 25 mm^2, then:

W₀ = 25mm^2

And we can replace it in the equation, then we get:

[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*t}[/tex]

We want to know the size of this wound after:

a) 1 day.

We know that t represents time in days, so here we just need to replace t by one, then:

[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*1} = 19.5 mm^2[/tex]

b) 1 week

Again, t represents the time in days, so we need to write this in days.

We know that:

1 week = 7 days.

then t = 7

The size of the wound after 7 days is:

[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*7} = 4.36 mm^2[/tex]

what is the height from the base of the statue to the tortch in inches

Answers

Answer: OK so I think Her Size (In a case like this it's ok to ask her size without getting in any trouble.): Her total overall height from the base of the pedestal foundation to the tip of the torch is 305 feet, 6 inches. Height of the Statue from her heel to the top of her head is 111 feet, 6 inches.

Step-by-step explanation:

This should be a simple problem, I think, simple calculate changing the feet to inches or yards, as the problem demands. I believe the height would be 1,813 inches (12 inches per foot), and the thickness of the arm would be 4 yards (3 feet per yard).

The two angles below are complementary angles. Find the value of a.

Answers

Answer: a = 43°

Step-by-step explanation: If two angles are complementary,

then the sum of their measures is 90 degrees.

So we can setup the equation 47 + a = 90.

Now subtract 47 from both sides to get a = 43°.

April and Bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars , while Bill bought 4 small chocolate bars and 3 large chocolate bars. If April paid $16.50 and Bill paid $11.25, what is the price of a single large chocolate bar?

Answers

Step-by-step explanation:

To  do this equation, we could put it in terms of algebra, lets say the large chocolate bars are represented by L and the small bars by S

April

4S + 6L = $16.50

Bill

4S + 3L = $11.25

Looking at this, we can see that the difference between the two purchases is that Bill bought three less large chocolate bars, this means the difference in total cost equals three large chocolate bars. Using this knowledge.

$16.50 minus $11.25 = $5.25

$5.25 = Three Large Bars

Divide this by three to get the cost of one large bar.

$1.75 is the cost of one single large bar.

Answer:

April: 4x+6y=16.5

Bill: 4x+3y=11.25

solving the two equations simultaneously will give you y=1.75
