Answer:

Let x = amount in low risk account, then 10000-x is amount invested in high risk account. To earn 10% of 10000:

(.10)(10000) = (.055)x + .12(10000-x)

1000 = 1200 -.045x

x = 4444.44 in low risk and 5555.56 in high risk

They can use counters or their fingers, but they can also use doubles facts. If they know 5 + 5 = 10, they know that the sum of 5 + 6 will be one more.

One of the four fundamental mathematical operations, along with addition, subtraction, multiplication, and division, is addition.

The sum of 5 + 6.

They can utilize counters or their fingers, but they can even utilize doubles facts. If they understand 5 + 5 = 10, they know that the sum of 5 + 6 will be one more.

Therefore, 5 + 6 = 11.

Estimating other doubles-plus-one facts together, such as 3 + 4, 7 + 8, and 9 + 8.

Repeat the doubles facts so they can use them to solve equations.

They can also use doubles-minus-one facts to enable them solve equations.

Write down 9 + 10 and have your children find the sum.

If they know that 10 + 10 = 20, they know that the sum of 9 + 10 will be one less. Therefore, 9 + 10 = 19.

Practice solving different number sentences together.

Therefore, they can utilize counters or their fingers, but they can even utilize doubles facts. If they understand 5 + 5 = 10, they know that the sum of 5 + 6 will be one more.

Therefore, the correct answer is option A 5 + 5 = 10.

The complete question is:

The answer to the given expression is 2

To "solve" or "isolate" a variable is to place it on its own side of the equation.

All other variables or constants should be moved to the opposite side of the equation using inverse operations. The operations must be applied to both sides of the equation in order to maintain the equation's balance.

Let's start by completing the first table.

The questions gives the depth in two times:

- 2 hours after start -> 64 inches of water

- 4 hours after start -> 48 inches of water

From this, we can identifythe units:

- for time, we will use hours

- for depth, we will use inches

The first given values are:

- for time, 2

- for depth, 64

The second given valuesa are:

- for time, 4

- for depth, 48

So, the table is:

Quantity Name | Time | Depth of Pool

Unit | hour | inch

Given Value 1 | 2 | 64

Given Value 2 | 4 | 48

Now, we need to calculate the slope, which can be done using the given points and the equation:

So, the slope is -8 inches per hour.

The interceptwe the b in the equation:

Where y is the depth and x is the time. So, using the first given values and the slope, we can find b:

Thus, the intercept is 80 inches.

So, the formula we have for the pump is:

Using it, we can answer questions 1 and 2:

1. After 6 hours means x = 6, so:

So, y = 32, thus, the depth of the water will be 32 inches.

2. The level 24 inches mean y = 24, so:

Thus, x = 7, and the water will be at 24 inches after 7 hours.

Measure of ∠B = 16°

∠A and ∠B are Vertical angles with ∠A = x+12° and ∠B = 6x-8°.

Vertical angles are angles formed between two lines at the intersection of them and are opposite to each other.

Also measures of Vertical angles are equal.

Now to find the measure of ∠B, we need to find x.

So here,  ∠A = ∠B

⇒ x+12° = 6x-8°

⇒ 6x - x = 12 + 8

⇒ 5x = 20

⇒ x = 4

Hence, ∠B = 6x-8° = 6 x 4 -8 = 16°

So measure of ∠B = 16°

Step-by-step explanation:

Hello!

A simple way to find if the number is a multiple of 9 is if the sum of the digits in the number is a multiple of 9, then the number itself is a multiple of 9.

So that means: 7 + 2 + b + 3 + 8 + 4 is a multiple of 9

If we add it up we should get: 24 + b

The multiples of 9 include 9,18,27,36,45,54....., and the closest multiple of 9 to 24 is 27. Therefore, the missing digit should be 3, as 27 - 24 is 3.

The next closest numbers would be 18 and 36, but you would need to add a negative number to get 18, and a two-digit number to get 36.

-When y = 0 :

10*x -8*0 = 16 (Replacing y=0)

10x = 16 (Multiplying)

x = 16/10 (Dividing on both sides of the equation by 10)

x= 8/5 (Simplifying)

- When x= 0:

10*0 -8*y = 16 (Replacing x=0)

-8y = 16 (Multiplying)

y= 16/(-8) (Dividing on both sides of the equation by -8)

y= -2 (Dividing)

- When x= 2

10*2 -8*y = 16 (Replacing x=2)

20 - 8y = 16 (Multiplying)

20 = 16 + 8y (Adding 8y to both sides of the equation)

20 - 16 = 8y (Subtracting 16 from both sides of the equation)

4 = 8y (Subtracting)

4/8 = y (Dividing on both sides of the equation by 8)

1/2 = y (Simplifying)

- When y= 4

10*x -8*4 = 16 (Replacing y=4)

10 x - 32 = 16 (Multiplying)

10x = 32 + 16 (Adding 32 to both sides of the equation)

10x=48 (Adding)

x = 48/10 (Dividing on both sides of the equation by 10)

x=24/5 (Simplifying)

Explanation: First of all we need to know if our triangle is a right triangle (has one 90° inner angle) to be able to use the law of sines to calculate the distance between Amanda and the helicopter.

Step 1: Once we know that the sum of all inner angles of a triangle is equal to 180° we can calculate the unknown angle as follows

As we can see above the missing inner angle is 90° which means it is a right triangle.

Step 2: Now we can use the law of sines as follows

once sin (90°) = 1 and sin (30°) = 0.5, let's calculate "x" below

Final answer: As we can see above, the final answer is 2000 ft

1) Solving that linear system using the elimination method, we'll proceed this way.

1.1 Choose one variable to be canceled out firstly. Let's choose the x variable:

6x + 5y = -15

-2x -3y= 17 Multiply this whole equation by 3

6x + 5y = -15

-6x -9y= 51 Add both equations

----------------------

0 -4y =36 Divide both sides by -4

y = -9

2) Now let's plug into any equation, usually the one with smaller numbers y= -9

-2x -3(-9) = 17

-2x +27 = 17 Subtract 17 from both sides

-2x =17-27

-2x = -10 Divide both sides by -2

x= 5

3) So the solution is (5, -9)

From the given question, we have the following parameters

Cost of a small greeting card = $1.60

The cost of a large greeting card = $4.05.

Cost of 5 small greeting cards = 5(1.60)

Cost of 5 small greeting cards = $8.00

Cost of 4 large greeting cards = 4(4.05)

Cost of 4 large greeting cards = $16.2

Cost of 5 small and 4 large = $8.00 + $16.2

Cost of 5 small and 4 large $24.2

Hence it would cost $24.2 to get 5 small greeting cards and 4 large greeting cards

Similarly;

Cost of x small greeting cards = 1.60x

Cost of y large greeting cards = 4.05y

Cost of small greeting cards and y large greeting cards = 1.60x + 4.05y

Hence it would cost $(1.60x + 4.05y) to get x small greeting cards and y large greeting cards

The most appropriate choice for supplementary angle will be given by-

x = 25.2°

∠AFB = 158.4°

∠RST = 21.6°

What is supplementary angle?

Angle is formed when two straight lines meet at a common point.

The common point is the vertex of the angle and the lines are called the arms of the angle.

Two angles are said to be supplementary if their sum is 180°

Here,

∠AFB = 7x - 18

∠RST = 72 - 2x

Sum = 7x - 18 + 72 - 2x

        = 5x + 54

By the problem,

[tex]5x +54=180\\5x = 180-54\\5x =126\\x= \frac{126}{5}\\x = 25.2[/tex]

∠AFB = [tex]7 \times 25.2 -18\\[/tex]

          = [tex]176.4 - 18\\[/tex]

What are Fractions?

Fractions are referred to as the components of a whole in mathematics. A single thing or a collection of objects might be entire. When we cut a slice of cake in real life from the entire cake, the part represents the percent of the cake. The word "fraction" is derived from Latin. "Fractus" means "broken" in Latin. The fraction was expressed verbally in earlier times. It was afterward presented in numerical form.

A piece or sector of any quantity is another name for the fraction. It is indicated by the sign "/," such as a/b. For instance, in the fraction 2/4, the bottom part represents the denominator, and the top part the numerator. This article's focus is on going to learn the meaning of fractions in mathematics, different sorts of fractions, how to convert fractions to decimals, and a ton of problems that have been solved and well explained.
