PLEASE HELP

Derek received a baseball card on his 10th birthday with a value of $25. It is predicted to increase in value by 2% per year. Derek sketches a graph of the value of his card over time.

Which statements are true about Derek's sketch?

Select each correct answer.




The graph curves upward.

The graph curves downward.

The x-intercept is at (25, 0).

The y-intercept is at (0, 25).

The graph is in the first and fourth quadrants.

The graph is in the first quadrant.

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

Answer:

Hexagon

Step-by-step explanation:

If in a regular polygon, each interior angle = 120 deg, then each exterior angle = 180–120 = 60 deg. So the polygon has 360 deg/60 deg = 6 sides. The figure is a regular hexagon.

Answer:

94600

Step-by-step explanation:

A hundred has 2 zeroes. To round a number to the nearest hundreds, just look at the last 2 digits (84). If it is 5 or bigger, add 1 digit (as I did in this exercise) and so it becomes 94600.

7, 24, 25

Step-by-step explanation:

Answer:  [tex]7, 24, 25[/tex]

Step-by-step explanation:

Hi there!

We can solve this using the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, a^2 + b^2 = c^2. We can plug each set of numbers into the equation, one by one, to see if the set of numbers is true in the equation. One thing to note is that the largest number out of the set is always the hypotenuse, or c. The other numbers are the legs (a and b.)

a^2 + b^2 = c^2

(5)^2 + (11)^2 = (13)^2

25 + 121 = 169

146 ≠ 169

Since 146 doesn't equal 169, this is NOT a right triangle

Since 657 doesn't equal 625, this is NOT a right triangle

This equation is true, because 625 = 625. Therefore this IS a right triangle.

Answer:

X∈∅

Step-by-step explanation:

4x + 5 = 6(x + 3) - 20 - 2x

distribute the 6

4x+5=6x+18-20-2x

collect like terms

4x+5=4x+18-20

4x+5=4x-2

cancel equal terms

5=-2

statment is false for any value of x

X∈∅

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]

Step-by-step explanation:

Answer:

x=50

Step-by-step explanation:

Answer:

x = 50

Step-by-step explanation:

So the equation is 2x+25=125. you first subtract the 25 from the 125 which you'll get 100 and then divided by 2 which leaves the x alone and so 100/2 = 50 so x= 50

Answer:

P = 9000000 × 6 100 = 9000000 × 0.06 = 540000 (answer) Therefore, the answer is 540000 is 6 percent of 9000000. Solution for '6 is what percent of 9000000?' The following question is of the type "P is what percent of W,” where W is the whole amount and P is the portion amount".

Answer:

75%

Step-by-step explanation:

I subtracted 6,750,000 from 9,000,000 and got 2,250,000.

I realized that that 2,250,000 is 25% of 9,000,000 so that leaves the remaining 6,750,000 to be 75%.

i am sorry if this doesn't make sense but that is how i figured it out.

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).

Answer

Just remember to divide the diameter by two to get the radius.

Step-by-step explanation:

If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation
