Put the given numbers into the given formula. It can be simplified a little bit.

Formula:

  V(t) = P(1 + r)^t

Coin A

  P = 25, r = .07

  V(t) = 25(1.07^t)

Coin B

  P = 40, r = 0.05

  V(t) = 40(1.05^t)

Answer:

He spent 11.25 minutes running

Step-by-step explanation:

Mr. Boyd completed a 3.19 mile walk/ run.

For every 5 minutes of walking, he ran for 1.5 minutes.

He completed his workout in 48.52 minutes.

Hence, we have the equation:

1.5x + 5x = 48.52 minutes

6.5x = 48.52 minutes

x = 48.52/6.5

x = 7.4646153846

Approximately = 7.5 minutes

Therefore the time spent running = 1.5 × 7.5 minutes

= 11.25 mimutes

Answer: Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage. For example, if your product costs $50 to make and the selling price is $75, then the markup percentage would be 50%.

Step-by-step explanation:

Answer:

hope this helps!

Step-by-step explanation:

Divide the amount added to the price by the amount the item costs you to buy to find the markup rate expressed as a decimal. In this example, you would divide $2 by $6 to get 0.3333. Convert the markup rate expressed as a decimal to a markup rate expressed as a percentage by multiplying it by 100.

Answer:

−18x+4

Step-by-step explanation:

Answer:

I looked online to find the equation well written, but i could not find it, so i will guess that the equation is:

[tex]\frac{3*a^{-2} - 2*b^{-6}*e^{-2}}{2*a^{-1}*b^{5}}[/tex]

Now we want to find the value of this equation when:

a = 3 and b = -2

So we can just replace these values in the equation, each a is replaced by a 3, and each b is replaced by a -2.

The equation becomes.

[tex]\frac{3*3^{-2} - 2*(-2)^{-6}*e^{-2}}{2*3^{-1}*(-2)^{5}} = 44.3[/tex]

Answer:

Step-by-step explanation:

For one flower, the following shapes are used;

6 yellow hexagons, 2 red trapezoids and 9 green triangles

If we are given 30 yellow hexagons 50 red trapezoids and 60 green triangles, to get the number of flowers we can make, we will find the greatest common factor of 30, 50 and 60

30 = 6*5

50 = (2*5)+40

60 = (9*5)+15

We can see that 5 is common to all the factors. This means that we can make 5 flowers if they were changed to 30 yellow hexagons 50 red trapezoids and 60 green triangles.

Since there are 40 trapezoids left and 15 green triangles left, hence the shape that would have n as left over most is trapezoid (40 left over)

Answer:

the answer is B

Step-by-step explanation:

here's why.... 2 times 4 plus 1 is 9 so ... 2 1/4 turns into 9/4 and 3 times 3 is 9 so if u place x with 3 it will be 9/4 therefore the fractions are equal.

Answer:

A

Step-by-step explanation:

Since the 2 legs are congruent then the triangle is isosceles and therefore the base angles are congruent, that is

∠ 2 = [tex]\frac{180-120}{2}[/tex] = [tex]\frac{60}{2}[/tex] = 30° , thus

3x - 6 = 30 ( add 6 to both sides )

3x = 36 ( divide both sides by 3 )

x = 12 → A

The second picture represents the addition of two vectors u and v by the parallelogram method for vector addition.

It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.

We have:

Two vectors u and v

The resultant vector will be u + v

As we know, in the parallelogram method for vector addition

We have to place two vectors at the same starting point.

Then complete the parallelogram.

The diagonal of the parallelogram represents the addition of the vector.

Thus, the second picture represents the addition of two vectors u and v by the parallelogram method for vector addition.

V = 288 cm³

Step-by-step explanation:

Given that,

The area of the base of a rectangular prism is 24 square centimeters and the height is 12 centimeters.

We need to find the volume of the rectangular prism. For a rectangular prism, the volume is given by :

V = lbh

Since, lb = A, area of the prism

V = Ah

V = 24 × 12

= 288 cm³

So, the volume of the rectangular prism is 288 cm³.
