Answer: $18.17

Step 1: Subtract 1 dollar.

$20 - $1 = $19

Step 2: Subtract 83 cents.

$19.00 - $0.83 = $18.17

Answer = $18.17

Answer: 6 trombones

Step-by-step explanation:

We can set up a proportion.

Let x be the number of trombones there are.

[tex]\frac{4 trombones}{6violas} = \frac{x trombones}{9 violas}[/tex]

We can cross multiply:

4*9 = 6x

6x = 36

Divide both sides by 6:

x = 6

Answer:

m∠CBD = m∠CDB ⇒ proved

Step-by-step explanation:

Let us solve the question

∵ AB ⊥ BD ⇒ given

→ That means m∠ABD = 90°

∴ m∠ABD = 90° ⇒ proved

∵ ED ⊥ BD ⇒ given

→ That means m∠EDB = 90°

∴ m∠EDB = 90° ⇒ proved

∵ ∠ABD and ∠EDB have the same measure 90°

∴ m∠ABD = m∠EDB ⇒ proved

∵ m∠ABD = m∠ABC + m∠CBD

∵ m∠EDB = m∠EDC + m∠CDB

→ Equate the two right sides

∴ m∠ABC + m∠CBD = m∠EDC + m∠CDB

∵ m∠ABC = m∠EDC ⇒ given

→ That means 1 angle on the left side = 1 angle on the right side, then

   the other two angles must be equal in measures

∴ m∠CBD = m∠CDB ⇒ proved

Answer:

After a 13-year span, the money in the account would be  $11.038.4.

As mentioned in the question,
Aubree invested $8,300 in an account paying an interest rate of 2.2% compounded quarterly.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Here,
principal(P) = 8300
rate(r) = 2.2% = 0.022
Time(a) = 13 years,
n = 4
Apply compound interest identity,
Amount = principal[1 + r/n]ⁿᵃ
Amount = 8300[ 1 + 0.022/4]⁴ˣ¹³
Amount = $11.038.4

Thus, After a 13-year span, the money in the account would be  $11.038.4.

Answer:

  15.07 hours

Step-by-step explanation:

The given relationship lets us write an equation in that uses rates in terms of tasks per hour. Let 'a' represent the number of hours it takes the assistant to grade exams alone. Then (a-2) is the number of hours it takes the experienced teacher. Working together, their total rate is ...

  1/a + 1/(a-2) = 1/7 . . . . . . . tasks per hour

  7(a -2) +7(a) = a(a -2) . . . . . multiply by 7a(a -2)

  14a -14 = a^2 -2a . . . . . . . eliminate parentheses

  a^2 -16a = -14 . . . . . . . . . subtract 14a

  a^2 -16a +65 = 50 . . . . add 64 to complete the square

  (a -8)^2 = 50 . . . . . . . write as a square

  a -8 = ±5√2 . . . . . . take the square root

  a = 8 +5√2 ≈ 15.072

It would take the teaching assistant about 15.07 hours to grade the exams alone.

Additional comment

The quadratic also gives an extraneous solution of about 0.93 hours. This results in a negative task time for the experienced teacher. That solution makes no sense in the given scenario, so we ignored it.

Answer:

20 yd^2.

Step-by-step explanation:

Area of base = 2^2 = 4 yd^2.

It has  4 side faces so:

Area of each triangular side = 1/2 * 2 * 4 = 4 yd^2

Total surface area = 4 + 4(4).

The aquarium would have a volume of 103950 cubic inches. Its dimensions are shown  in the image attached.

An aquarium is a container, often made of glass or acrylic, in which aquatic plants and animals are kept for display or research purposes. It can also be a building or room that houses such tanks.

We have been told that the volume of the water that can be held by the aquarium is 450 gallons of water. If we convert the gallons to cubic inches we would obtain 103950 cubic inches. The dimensions of the aquarium must therefore be such that it would a volume of 103950 cubic inches.

Answer:

The third one would be the option.

Step-by-step explanation:

If the tree is already at 18 inches on the 2nd year, then it would be at 9 inches on the first year, and at 27 on the third year. And so on.

Graph [3] represents the growth of the tree in inches per year.

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. Mathematically, direct proportionality is represented by a straight line and it equation is of the form -

y = kx

k = y/x

where [k] is the constant

Given is a tree in Dante's neighborhood grew 18 inches in the first 2 years after it was planted. The tree continues to grow at this same rate.

Since the tree grew 18 inches in the first 2 years and continues at the same rate, then it will grew by (18/2) or 9 inches per year. The equation that will represent this relation between growth [y] and time [x] is given by -

y = 9x

Graph number [3] represents the relation.

Therefore, graph [3] represents the growth of the tree in inches per year

90 : 54 : 36

Step-by-step explanation:

Add the ratios:  5 + 3 + 2 = 10

Divide 180 kg by 10:  180 ÷ 10 = 18

Multiply each number of the ratio by 18:

5 × 18 : 3 × 18 : 2 × 18

⇒ 90 : 54 : 36

Angles 2·x + 2, and x + 50, formed by the transversal are alternate

exterior angles, which gives, x = 48°, the correct option is therefore;

A) 48

From the position of the angles image showing two parallel lines having

a common transversal we have;

Angle 2·x + 2 and angle x + 50 are alternate exterior angles

The alternate exterior angles formed by two parallel lines that have a

common transversal are equal, therefore;

2·x + 2 = x + 50

Which gives;

2·x - x = 50 - 2 = 48

x = 48°

Brianna's car

Step-by-step explanation:

Looking at the first equation the car decreases by 15% each year.

So our depreciation rate is 15%

The second equation represents an exponential depreciation with a depreciation rate given by;

1-0.9=0.1×100=10%

So our depreciation rate is 10%

Of course Brianna's car is decreasing in value quicker, since the car loses more value as the depreciation rate is higher.

Answer:

D

Step-by-step explanation:

Letter D is the only answer that gets the transformation of triangle ABC correct, since it is the only answer that describes a reflection across line p.

Letter A describes a reflection across the y-axis, which is incorrect because the triangle on the right is farther away from the y-axis than the triangle on the left.

Letter B describes a reflection across the x-axis, which is incorrect because the topmost triangle is farther away from the x-axis than the bottommost triangle.

Letter C once again describes a reflection across the y-axis, which is incorrect for the same reason as to why letter A is incorrect.

Therefore, the answer must be letter D.

Answer:

9

Step-by-step explanation:

Jumping = 36/4 = 9

Lifting weights = 36/2 = 18

Running = 36-(9+18) = 9

Answer:

9 people

Step-by-step explanation:

First, we need to find out what fraction of the class is running. If 1/4 of the class is jumping, and 1/2 of the class are lifting weights, and the remaining people are running, this can be written like this. 4/4 - 1/4 - 2/4 = 1/4

1/4 of the class is running. Now we need to find out how many students is 1/4 of the class. To find this, we need to divide 36 by 4, which is 9. This means 9 people are running in gym.

I hope this helps :)
