$5.40+$8.70+$6.30


plz help this is fifth grade math and it is using compensations and it is hard​

The final amount of money was $50, they spent half of what they collected on canned foods, so 50 x 2 = 100.

They collected a total of $100.

Let the amount Eric collected = X

Charlotte collected 3 times as much minus $20, writing this as an equation you get 3x-20.

Now you have Eric plus Charlotte = $100:

x + 3x-20 = 100

Combine like terms:

4x-20 = 100

Add 20 to both sides:

4x = 120

Divide both sides by 4:

x = 120/4

x = 30

Eric = X = $30

Charlotte = 3x-20 = 3(30) - 20 = 90 -20 = $70

Answer:

40

Step-by-step explanation:

the the answer is 40 because if you do 40 * 3 to get 120 and if you minus 20 then you get a hundred in a hundred divided by 2 equals 50

what you do is you do 50 * 2 but you got to 100 then you add 20 which gives 220 then you ÷ by 3

Answer:

The area of the polygon is 64 units²

Step-by-step explanation:

* Lets explain how to solve the problem

- The polygon has 5 sides and 5 vertices

- To find its area by easy way split it into two trapezoid by a horizontal

  line y = 1

- The vertices of trapezoid (1) are (-5 , 1) , (4 , 1) , (-5 , 5) , (0 , 5)

- The vertices of one of the parallel bases are (-5 , 1) , (4 , 1)

- The length of this base = 4 - (-5) = 4 + 5 = 9 units

- The vertices of the other parallel bases are (-5 , 5) , (0 , 5)

- The length of this base = 0 - (-5) = 0 + 5 = 5 units

- The length of its height = 5 - 1 = 4 units

- The area of the trapezoid = 1/2 (b1 + b2) × h

∴ Area of trapezoid 1 = 1/2 (9 + 5) × 4 = 28 units²

- The vertices of trapezoid (2) are (4 , 1) , (-5 , 1) , (-5 , -5) , (-2 , -5)

- The vertices of one of the parallel bases are (4 , 1) , (-5 , 1)

- The length of this base = 4 - (-5) = 4 + 5 = 9 units

- The vertices of the other parallel bases are (-5 , -5) , (-2 , -5)

- The length of this base = (-2) - (-5) = -2 + 5 = 3 units

- The length of its height = 1 - (-5) = 1 + 5 = 6 units

∴ Area of trapezoid 1 = 1/2 (9 + 3) × 6 = 36 units²

∵ Area of the polygon = Area trapezoid (1) + Area trapezoid (2)

∵ Area trapezoid (1) = 28 units²

∵ Area trapezoid (2) = 36 units²

∴ Area of polygon = 28 + 36 = 64 units²

∴ The area of the polygon is 64 units²

Answer:

David would have to drive for 415 miles before he reaches his $200 budget.

Step-by-step explanation:

It cost $27.95 per day to rent a car and he is only renting it for 3 days. ($27.95 x 3 = $83.85 for all three days). When you subtract $83.85 from his $200 budget you get, $116.15. It is .28 cents for each mile. Next you divide $116.15 by .28 cents to equal 414.82 miles. Round the miles to a whole number to get 415 miles.

Answer:

[tex]7000\times 50 = 3,50,000 = 35\times 10^4[/tex]

Step-by-step explanation:

We have to find the product of 7,000 and 50 and express it in the form of product of a whole number and power of 10.

First, we will find the product.

[tex]7000\times 50 = 3,50,000[/tex]

Now, we have to express this product as a sum of whole number and power of 10.

3,50,000 can be written as:

[tex]3,50,000 = 35\times 10^4[/tex]

Here, 35 is our whole number and [tex]10^4[/tex] is required power of 10.

We used the rule of exponents to express the product in such manner.

The digit 6 in January represents 60,000 due to its position in the 'ten thousands' place, whereas in February's count, the digit 6 represents 600, due to its place in the 'hundreds' place.

The value of a digit in a number depends on its position within that number, otherwise known as its place value. In the number 160,341 (representing the number of boxes of paper in January), the 6 is in the 'ten thousands' place, making it worth 60,000. In contrast, the 6 in the number 32,698 (representing the number of boxes in February) is in the 'hundreds' place, making it worth 600. Therefore, the digit 6 in January has a larger value than the digit 6 in February.

Answer:

23

Step-by-step explanation:

Whenever you subtract a negative number, you treat it as if you're adding a positive number.

For example:

-5-(-5) becomes -5+5, which is 0.

So, 4-(-19) becomes 4+19, which is 23.

Answer:

27,000 times.

Step-by-step explanation:

We have been given that the mass of Earth’s Moon is about [tex]7\times 10^{22}[/tex] kilograms. The Mass of Jupiter is about [tex]1.89\times 10^{27}[/tex] kilograms.  

To solve our given problem, we will divide mass of Jupiter by mass of Earth's moon.

[tex]\frac{1.89\times 10^{27}}{7\times 10^{22}}[/tex]

Using property [tex]\frac{a^m}{a^n}=a^{m-n}[/tex], we will get:

[tex]\frac{1.89}{7}\times 10^{27-22}[/tex]

[tex]0.27\times 10^{5}[/tex]

[tex]0.27\times 100000[/tex]

[tex]27,000[/tex]

Therefore, the mass of Jupiter is 27,000 times the mass of Earth’s Moon.

The area of the regular hexagon is approximately 2.598 cm².

Finding the Area of a Regular Hexagon

To find the area of a regular hexagon with a side length of 1 cm, we can use the formula for the area of a regular polygon:

Area = (3√3 / 2) × s², where s is the side length.

Given that the side length ( extbf{s}) is 1 cm:

Square the side length: 1² = 1 cm²

Multiply by (3√3 / 2): (3√3 / 2) × 1 cm² ≈ 2.598 cm²

Thus, the area of the regular hexagon is approximately 2.598 cm².

square of 15 = 225

The Number must be between 14 and 16

Answer:

The number will lie between 14 and 16.

Step-by-step explanation:

If the square of a whole number is between 200 and 250 then the inequality formed will be

200 < x² < 250

where x is a whole number.

Now we will simplify this inequality.

[tex]\sqrt{200}<\sqrt{x^{2} } <\sqrt{250}[/tex]

14.14 < x < 15.81

By approximation, 14 < x < 16

Therefore, the number must lie between 14 and 16.

Answer:

18x²-45x

Step-by-step explanation:

Final answer:

To find the product of negative 9 and (5 minus 2x), use the distributive property, resulting in -45 + 18x.

Explanation:

The product of negative 9 and (5 minus 2x) can be found by applying the distributive property. This property states that a number multiplied by a sum or difference in parentheses is equivalent to the number multiplied by each term inside the parentheses separately, and then summing the results. So, the product will be:

Negative 9 multiplied by 5, which gives -45.

Negative 9 multiplied by -2x (note the two negatives make a positive), which gives 18x.

Combining these two products, we get the final answer, which is -45 + 18x.

Answer:

a.No b.No c.Yes d.No

Step-by-step explanation:

A. [tex]2^{2} + 3^{2} = 4^{2}[/tex]

4 + 9 = 16

13 [tex]\neq 16[/tex]

So for A a triangle cannot be drawn.

B. [tex]2^{2} + 3^{2} = 6^{2}[/tex]

[tex]2^{2} + 3^{2} = 6^{2}[/tex]

4 + 9 = 36

13 [tex]\neq 36[/tex]

So for B a triangle cannot be drawn

A triangle is equal to 180 degrees

C. 90 + 45 + 45 = 180
